This invention relates to the art of surgical operating tables .andin particular hasreference to'an operating table that includes a support base that is interchangeably useable with a plurality of separate body supporting tops, with individual tops being provided to provide anatomically contoured supportf-or a human body in the prone, supine. and unilateral positions. I
In the past, operating tables have: been made up, in general, of. a plurality of support surfacesarranged contiguously to-each other in. articulated fashion so as to provide adjustable supportfor ahuman body in various in supine position, there are, nonetheless, occasions where prone or unilateral patient position isrequired for the.
purpose of proper surgical operating approach.
In the past, operatingtables have beenc-ompromisedin design, with the thought in mind of accommodating a patient in all positions, with no provision being made for theuse of separate interchangeable tops thatwould support the patient in the various requisite operating positions.
Additionally, and because of the limitation that the prior art operating table must support a patient inall operating positions, it has been necessary in the past to make the operating.tableofsuflicint width tosupport a patient in the various positions required for surgical operations. As a result ofv this fact, tables of the prior art have been rather large intransverse dimensions so as to limit the approach available to the operating surgeon.
Ithas been discovered that greatly improved results can be achieved by providing individual operating tops that are respectively and anatomically contoured to firmly support a patient in prone, supine and-unilateral position, with the tops being interchangeably engageable with a common pedestal base that serves to move the articulated components of the. individualized tops. In basic essence, it is preferred to have each topinclude an articulated twopiece torso support that is connected in articulatedfashion to appropriate leg supports, arm supports anda head support. i
The net eflect of such contouringof the patientsupports is to provide a more even distribution of I a patients weight over a greater surface area.
Thus, on a flat top type of table, there. would be no. support for the small of thejpatients. back and other regions, whereas in use of contoured support elements,
support for such areas in provided.
Further, it is preferredthat thetorso supporting portion of each top be connected to two adjustment control means provided on the pedestal base, with the preferred 3,227,449 Patented Jan. .4, 1966 It has been further discovered that such individualized construction further enhancesthe surgeons accessibility to the operative area, with the utilization of the three tops eliminating the engineering compromises that were inherent in the single top designs of the prior art and with the three tops being designed to provide maximum accessibility to an infinite number of surgical positions.
As a practical matter, forming of the supporting sections to body conforming contour, is possible because the science of human engineering reveals that the torso dimension of individuals varies only slightly notwithstanding rather considerable differences in height. Thus, the various torsosof persons having various heights can be comfortably supported on the same torso supporting portion of the top with the result thatdiflerent size table tops are not required for different height individuals.
A combination of this contour supporting with the flexing at the hinge point of the human torso has the further advantage of providing amore comfortable type of patient support during periods when the torso is in flexed condition; Thus, in the contoured flexing arrangement of the instant invention, the hip portion is firmly supported with respect to the legs while the back portion of the torso is flexed by the adjustable back support for example.
By way of contrast, in the. prior art, both portions of the torso .Would be moved relatively of the limbs of the patient to accordingly cause a greater degree of strain on the patient duringv the operation. By use of the improved. principle herein involved, it has been found that such undue strains are materially reduced.
Production of an improved operating. table having the above characteristics becomes the principal objectof this invention, with other objectsthereof becoming more apparent upon a reading of the. following brief specification, considered and interpreted in the light of the accompanying drawings.
By way of general. introduction to the drawings, the same illustrate the pedestal base being respectively connected to the supine, prone and unilateral tops, with FIG- URES 1 to 8 being directed to the use of the supine top,
while FIGURES 9 to 15 are directed'to the description of the prone top. FIGURES 16 through 24 are similarly directed tothe description of-the unilateral top, while FIGURES 25 through 31' are" detailed with respect to the construction of the pedestal base per se.

For the purpose of clarifying the description of the improved operating table, it is felt that the best approach can be made by describing the individual tops per se, followed by a detailed description of the pedestal base that is interchangeably associated with all of the tops shown in the preferred form of the invention. Accordingly, a separate description will be undertaken with respect to each of the tops, as well as the pedestal base.
Accordingly, the operating table, generally indicated by the numeral 10, includes a base 11 that is selectively engageable with either a supine top 100, a prone top 200 or a unilateral top 300, depending upon the operation to be performed, with the tops 100, 200 and 300 each being of articulated construction and each having the position of the torso supporting portions thereof controlled by the operating mechanism of the pedestal base 11, as will be subsequently described.
THE SUPINE TOP Referring first to FIGURES 1 through 8 of the draw ings, the supine top, which has been generally designated by the numeral 100, includes, as best shown in FIGURES 1, 4 and 5, a back support 101 that is connected, in articulated fashion, to a hip support 102, with leg supports 103, 103 being pivotally connected to the hip support 102, while arm supports 104, 104 are connected to the back support 101 for the purpose of supporting the patients arms. A head support 105 projects from one end of the back support 101 for the purpose of supporting the patients head during the operation.
In this fashion, and as will be described, the operating top 100 is accordingly made up of articulated members 101, 102, 103, 104 and 105 that have been just described.
With regard to the just described components, it should be first noted that the same are anatomically contoured in configuration so as to provide a form fitting type of support for the patient. Thus, and as shown in FIG- URE 4, the hip portion 102 is dished to conform to the normal hip contour, while the back support 101 is contoured to a lesser extent to appropriately support the normal back of a patient. Similar contouring of the leg supporting members 103, 103, the arm supporting members 104, 104 and the head supporting member 105 has been provided for as shown best in the perspective illustration of FIGURE 1.
In this fashion, the patient will be comfortably supported on his back, with the individual components of this supine top being contoured so as to snugly envelope the supported areas of the patient in form fitting relationship therewith, thus providing support against transverse shifting which frequently occurs in instances of supporting a patient on a flat top type of table.
Referring now to further details of construction with regard to the just described components, it will first be noted that the hip support 102 includes a contoured body portion 109 that is secured to a supporting casting 110 so as to define the hip support that has been generally designated by the numeral 102.
For the purpose of coaction with the leg supports 103', 103, the casting 110 includes opposed support bosses 111, 111 (FIGURE 5), with these bosses being intended to pivotally support the leg supports 103, 103 so that the same may be moved through the approximate plane of the hip support 102 between full and chain-dotted line positions, as shown in FIGURE 4. Referring now to FIGURE 2 for a detailed consideration of the boss members 111, 111, it will be noted that the same include a cylindrical projection 112 that is provided with a bore 113 within which a support shaft 114 may be appropriately journaled. Positioned within the lower portion of the bore 113 is a gear 115 that is preferably fixed with respect to the cylindrical portion 112 and that is further provided with an aperture 116 within which the lower end of the shaft 114 may be slidably received, with the upper end of the shaft 114 also being journaled within a sleeve or bushing 117 so as to make the shaft 114 slidable axially with respect to the boss 111.
For the purpose of connecting with the leg supports, each boss 111 further includes a slot 118 within which the bifurcated end 121 of the support arm 120 may be inserted, with the end 121 being pinned, as by pin 122, to the shaft 114. The lower portion (FIGURE 2) of the bifurcated end is undercut to receive a rack insert 123, with the teeth of the rack insert 123 being designed to mesh with the gear 115, as best shown in FIGURE 3 of the drawings. In this fashion, when the leg support is in the position of FIGURE 2, the teeth of the gear 115 and the rack 123 are meshed so that rotational movement of the shaft 114 with respect to the boss 111 is prevented. However, when it is desired to rotate the leg support 103, it is merely necessary that the same be lifted to elevate the shaft 114 with respect to the boss 111 and at this time the teeth of the gear 115 and the rack 123 become disengaged so as to allow rotational movement of the leg supports 103, 103 between the full and chain-dotted line positions of FIGURE 4.
In addition to the bosses 111, 111, the support plate 110 further includes a pair of wedge blocks 130, that converge towards each other for the purpose of becoming interlockingly engaged with a keystone type of key alignment that is provided on the pedestal base 11, with these wedge blocks 130, 130 having tapered edges 130a, 130a (FIGURE 8) so as to prevent vertical (FIG- URE 1) disengagement when the same have been locked in place as will be described.
To the end of effectuating articulated connection, with the back support 101, the supporting casting 110 further includes projecting arms 131, 131 (FIGURES 5 and 8) that are provided with a notch type of recess 132, with the notch 132 serving to limit rotational movement between the members 101 and 102.
Considering next the detailed construction of the back support 101, it will first be noted that the same is again of conventional construction so as to include a contoured and/or laminated body portion 135 that is bonded or otherwise secured to a rigid support casting or plate 136 that is appropriately contoured for articulated connection with respect to the component parts 102, 103, 104 and 105.
To this end and referring first to FIGURE 8, articulated connection with respect to the hip support 102 is effectuated through the use of depending support arms 136a,
through the medium of a pin 137.; An arm,138 of'generally U-shaped configuration has the free ends ofthe' leg portions thereof pivotally connected to the outermost arm members 136a, 136a so as to extendtransversely over the arms 131,13;1-,with the. base portion. of the member 138 being intended to be positionablein the slot 132 during periods of top storage so as to lock themem-- bers 101 and 102 against inadvertent pivotal movement with respect toeach other, with springi139 urging the 1 member 138 towards the chain-dotted line position of:
FIGURE 8 by virtue of its biased connection between the members 136a and 138. In this fashion, the .base of.
the locking member 138 willnormally ride on the top face of the arm 131 so as to permit controlled articulation between the members 101and 102, but will snap.
into locked position upon mere lifting of the member 101 into the chain-dotted line position of FIGURE 8.
For the purpose of achieving articulated connection with respect to the head support 6, to provide a support boss 140 that serves asa pivotal support for 1) both thesupport-castingor plate 14-2 and (2) a control arm 143, with the boss 140being slotted, as at 144 and 145, for this purpose. In this regard,-the walls of the. slot 144support a pin 146 about which the support plate 14-2 can be journaled, while a second pin 147' is carried in the slot 145 for the purpose ofbeing journaled within the eyelet end 143a of the support arm 143 as shown in FIGURE 6.
The remaining support components of the support plate 136 includeopposedbosseslSO, 150 that serve, in general, to provide pivotal support for the arm. supports 1 104, 104. with this pivotal connection being best shown in FIGURES and 7 of the drawings.
Accordingly, and as shown in FIGURE. 7, -the1bossesu 1,50, 150 are each provided with afixed gear element 152, while a similar fixed gear element 158is provided on each support plate 159 of the arm supports 104, 1041 An. elongate armlS-l pivotally interconnects the plate 136 with the plate 159 by having its ends provided with gears 153 and 157 that are intended to respectively mesh with gears 152 and 158, with'bolt 154 pivotally journallingt.
one end 151a of the arm 151 with respect toboss 150, While bolt 160 journals the remaining end-15-1b of arm 151 with respect to support plate 151 by virtue of the threaded end 160a of bolt 160 beingreceived ina tapped opening in plate 159. A spring 155 normally urges the gears 152 and 153 intoregistry as shown in FIGURE '7.
In this fashion, while the gear members 152 and-153 are normallyurged into registry by spring 155, but the same can be separated .by liftingthe arm end 151a withinthe confines of the slot 156 that is provided in eachboss member 150, as clearlyshown in FIGURE 7 of the drawings.
and the plate 159, with this detail being shown best in the right-hand portion of FIGURE 7 ofthe drawings where gear elements 157 and 158 are shown gravitationally engaged in registry, with the gear element 157 being fixed with respect to the armend"151b, while gear 158-isfixed with respect to support plate, 159. To facilitate rotational adjustment at this point, clearance is providedbetween includes a fiat area generallydesignated bythe numeral P 162 (FIGURE 5), with this fiat area being intended to engage with an appropriate roller element of thepedestal base and thus provide a support surfacefor controlling v 105, the support'plate 136 is further contoured, as shown in FIGURES 5. and" A similar type of connection is effectuated between the remaining opposed end 1515 of each arm 15L 6" the articulated connection between these just described components.
With regard to the detailed construction of the individual leg supports 103-, 103, it has been previously indicated that the same are pivotally connected with respect to thehip support102 through the medium of the pivotal arms 120, -and if reference will be made to FIGURE 2, it will be noted that the arm 120 connects to a support casting or plate 163 that, in turn, is connected to the contoured body support portion 164 that defines each leg support 103.
Similarly, the head support 105 has been indicated as including a support casting or plate 142- that is pivotally mounted with respect to the support casting or plate 136.
With regard to the details of such construction and referring to FIGURE6, it will be noted that the support plate 142 connects toa contoured body portion 166 that provides support for the patients head as previously noted. Additionally, the plate 142 further includes a boss 167 that isprovided with a slot 168 having a tooth 169 provided therein, with the tooth 169 being adapted to be selectively engaged with the teeth 170 that are provided on the arm-143 with spring 169a urging the tooth 169 into registry with teeth 170. Thus, the head support 105, can be retained in any condition of pivotal relationship with respect to the back support 101 by mere manipulation of the arm 143 by its, handle portion 1415b:
With regard to the detailed construction of the arm' portions are preferably formed from plastic material reinforced with fiberglass or other equivalent material that is in turn reinforced by the support plates to provide a rigid support. For patients comfort, flexible pads may be provided over the various body portions, with a pad coveringthe support members 101, 102'and 105, while pads 1-81, 181 cover the leg supports 103, 103. Pads 18-2, 182 similarly cover the body portion of the arm supports 104, 104.
THE PRONE TOP- 200 The prone top 200 is shown in FIGURES 9 through 15 of the drawings and is provided for the purpose of supporting a patient in-prone or face down position, with two alternate positions of patient support being provided in this regard in connection with the prone top 200. On this point,FIGURE 9 indicates the option of a prone top wherein the patient -is, in effect, in prone kneeling position; In FIGURE 10, alternate leg supports are provided to position the patient in substantially flat prone position. Itfollows that theone-leg support of each type'could be used so that one leg would be in kneeling position while the other would be in straight or extended position.
Referring first to FIGURES 11, 12 and 13, the prone top 200, in general, includes a chest support 201, an abdominal support 202,-arm-supports 203, 203,21. face support 204, andyleg supports 205, 205 (FIGURES 9, 11, 12
. and 14) or 206, 206 (FIGURES 10, 13 and-15) with the aforesaid components being joined together in articulated fashion to define the top 200 as will now be de scribed.
Accordingly, and; considering first the abdominal sup.-
port 202, the same is shown asincluding ananatomically pose of pivotally connecting the leg supports 206, 206 with respect to the support plate 211, as will be described.
With reference to the detailed construction of plate 211, it will be first noted that the same is of box like construction so as to have its lower face 211a provided with tapering guide blocks 216, 216 that complementally engage a tapered block provided on the pedestal base, with each block 216 having a tapered surface 216a so as to obviate the possibility of disengagement between the top and the base when the same are positioned in interlocking relationship as shown in FIGURE 9.
The support plate 211 further has projecting spaced support arms 218, 218 that are appropriately bored to receive the connector pin of any of the leg supporting elements 205, 205 or 206, 206. Additionally, the support plate 211 further includes a pair of parallel projecting arms 219, 219 that receive therebetween a boss portion 220a that is defined by the support casting or plate 221 of the chest supporting element 201, with these members 219 and 220a being rotatably connected by pin 221:: as shown best in FIGURES 14 and 15 of the drawings.
Referring next to FIGURE 12, the support plate 221 further includes bosses 222, 222 that pivotally support arms 223, 223, with arms 223, 223 in turn being pivotally attached to support castings or plates 224, 224 that serve to reinforce the contoured body portion 224a of each arm support 203.
In this regard, the articulated connection of each arm 223 with respect to each boss 222 and each support plate 224 conforms preferably to the type of articulated connection shown in connection with the prone top and previously described in connection with FIGURES 1 through 7 of the drawings. Accordingly, redescription of the component elements will not be undertaken at this point, with it sufiicing to say that the arm 223 pivots relatively of both the boss 222 and the support plate 224 so as to be positionable in an infinite number of supporting positions.
By like token, the head support 204 has a support casting or plate 225 that is pivotally connected to the support plate 221 in the exact same fashion as was the case in connection with the head support 105 previously described in FIGURES 5 and 6 of the drawings with a contoured body portion 225a being secured to the plate 225 as was previously the case. It sufiices here to say that movement of the handle 226 facilitates pivotal movement of the head support 204 relatively of the chest support 201, with the handle serving to lock the head support 204 in any desired position of pivotal relationship with respect to chest support 201. A flat surface 229 (FIGURE 12) is provided for enga ement with control elements of the pedestal base as will be described.
Turning next to a detailed description of the leg supports 205, 205 that are shown in FIGURES 9, 11, 12 and 14 of the drawings, it will first be noted that each leg support includes an elongated arm 230 that has an enlarged end 231 within which a pin 232 is fixed, with the pin 232 having its ends receivable in the apertures provided in the support arms 218, 218.
The elongate arm 230 further has an elongate groove 230a (FIGURES 14 and 14A) that is provided with a plurality of teeth 230b, 2301), that extend longitudinally of the slot 230a as shown in the drawings. The contoured body portion 235 of the knee supporting member has a rigid housing 236 secured thereto and projecting from the frontal edge thereof as shown in FIGURE 14, with this housing 236 being of appropriate size and configuration so as to telescopically encircle the arm 230 and thus be slidable relatively thereof in an axial direction, with locking of the unit in place being effectuated by the use of a spring loaded dog member 237 that is pivotally secured to the housing 236 as clearly shown in FIGURE 14 of the drawings.
Thus, the patients knee can be positioned on the pad 238 of the contoured body support 235 and properly adjusted relatively of the arm 230 by merely sliding the same upwardly until the proper position is reached with locking in place of the unit automatically occurring by virtue of the connection of the end of dog member 237 with the teeth 23015.
With regard to the detailed construction of the leg supports 206, 206 that are shown in FIGURES 10, 13 and 15, it has been previously noted that each includes an elongate arm 213 that has a pin 246 secured therewith so as to be insertable in the openings provided in the support arms 218, 218. The arm 213 further connects to a support plate 247 that, in turn, provides reinforcing for the elongate contoured leg supporting body portion 248.
With regard to the insertion and removal of any of the leg supporting members above described, it has been previously indicated that each such element includes a pin member, with the pin 232 being described in connection with each leg 205, while a pin 246 is shown for each leg support 206. It will be noted that clearance is provided in each instance between the arm and further that the pin in question projects beyond both faces of the supporting arm 230 or 213.
In this fashion, the main arm of either leg support can be lifted and one end of the pin disengaged, followed by removal of the other end of the pin, with the parts normally being retained in place by gravity and patient weight when positioned as shown in FIGURES 14 and 15.
THE UNILATERAL TOP 300 The unilateral top 300 shown in FIGURES 16 through 24, is designed for the purpose of supporting the patient on either side and, accordingly, the drawings have been made with the purpose in mind of illustrating how the unilateral top 300 can be used to support the patient on either the right or left side, depending upon the operative site in question.
Accordingly, and referring to FIGURE 16, the unilateral top 300 is shown aranged to support a patient on his or her left side, while in FIGURE 17 the top 300 is arranged opposite hand so as to support a patient on the right side.
With regard to the general construction of the unilateral top 300, it will be first noted that the same is made of articulated construction so as to include a hip support 301, a chest or upper side support 302, an arm support 303 and a leg support 304 with the arm support 303 and leg support 304 being reversible in position so as to support the patient on either side as desired.
Referring first to FIGURES 18, 19 and 20, the hip support 301 is shown as including a fabricated support casting or frame 310 that connects to the contoured body portion 311 so as to provide support for the hips of the patient during positioning on the top 300. The support frame 310 includes, as before tapering guide ways 312, 312 that have tapered faces 312a, 312a (FIGURE 17) for engagement with a component of the pedestal base in interlocking relationship therewith. Further, the supporting member 310 includes projecting, rigidly mounted support arms 314, 314 that are preferably T-shaped crosssectional configuration (FIGURE 23) so as to releasably support the leg supporting element 304, as will be described.
For the purpose of connection with the arm support 302, one leg portion 315a of a hinge 315 is shown connected to the frame 310 as shown in FIGURE 22 with the remaining leg portion 315b of hinge 315 being secured to the frame 320, of support 302 so as to effectuate a hinged connection between these components as shown in FIGURE 22.
Referring next to FIGURES 16, 17, 18 and 22 for a detailed description of the leg support 304, it will be first noted that the same is somewhat V-shaped in plan and is designed to have either of its opposed ends 304a and 304b connected to the hip support 301, with end 30% being connected in FIGURE 16, while end 304a is connected to hip support 301 in FIGURE 17 of the drawings.
In construction, the leg support 304 is reinforced throughout a substantial portion of its longitudinal extent by a U-shaped support channel321 (FIGURE 23) that connects with end plates 322 and 323, with end plates 322 and 323 being identical but being disposed adjacent the leg support ends 304a and 304b respectively. Accordingly, and to facilitate mounting, each end plate 322 and 323 includes a pair of substantially T-shaped slots 324, 324, with the outline configuration of the slots 324, 324 being best shown in FIGURE 23 of the drawings, and with the slots 324, 324 being best shown in FIGURE 23 of the drawings. For the purpose of preventing longitudinal movement of the leg support 304 relatively of arms 314, 314, transversely extending U-shaped channels 325, 325 are preferably connected with regard to frame 321 at a point spaced inwardly from each end of the leg support 304, with the channels 325, 325 being intended to receive the head 326a of a bolt 326 that is carried by the projecting end of the arm 314, with this locked condition being best shown in FIGURES 23 and 24 of the drawings.
Accordingly, when it is desired to disengage the leg support 304, it is merely necessary to lift the same so that the head 326a becomes disengaged from the channel 325, at which time the same can be longitudinally removed with respect to the T-shaped support arms 314, 314 that pass freely through the slots 324, 324.
In the unilateral top 300, the preferred embodiment shown does not envision the use of an adjustable head support and, accordingly, the member 302, which has been described as the chest or upper side support, in reality includes a head supporting portion that is integral therewith. Accordingly, and for the purpose of providing such support the frame 320 is connected to a contour body support 327 that is shown contoured to receive either side of the head, shoulders and upper side portion of the patient, while leg support 304 and arm support 303 may be selectively positioned to support the arms and legs of the patient on either side.
To this end, the support member 302 further includes a support casting or plate 330 (FIGURES 18, 19 and 20), with this support plate being designed to pivotally support the arm support 303, as well as toprovide support for the body portion 320 thereof. A wear plate 331 is also provided for the purpose of coacting with components of the pedestal base as will be described.
Referring next to FIGURES 20 and 21 for a detailed description of the manner in which the arm support 303 is connected with regard to the chest and head support 302, it will be first noted that the boss 330 is tapped to receive a bolt 335, with the bolt 335 being keyed or otherwise fixedly secured to a gear 336. An arm 340 has opposed ends 341 and 342 with end 342 being bored to be pivotally journaled around the shaft portion of bolt 335 as clearly shown in FIGURE 20 of the drawings. Additionally, the arm 340 has trunions 344 and 345 within which contoured control rods 346 and 347 may be slidably supported, with the end of rod 346 being formed to be engageable with the teeth of gear 336 as shown in FIGURE 21.
In this regard, the rods 346 and 347 are connected with respect to eccentric points on the control lever 348 through the medium of springs 350 and 351, respectively, with these springs tending to normally urge the control element and rods 346 and 347 to the position of FIG- URE 21 where the end of the rod 346 is shown being in engagement with the teeth of the gear 336. In this fashion, when the control lever 348 is moved to the chaindotted line position, the rod 346 will have its end portion retracted from meshing engagement with the gear 336, at which time the arm 340 will be free to rotate around its. point of pivotal connection with respect to bolt or shaft 335. A similar type of connection is utilized between the end 341 and the support casting or plate 355 that is associated with the arm support 303. In this regard, a shaft or bolt 356 is connected to the support 355 and supports a fixed gear 357 that is designed to be engaged by the projecting end of the rod 347. Accordingly, and as before, when the control lever 348 is moved to the chain-dotted line position, the end of rod 347 will be disengaged from the gear 357, thus permitting rotation of the arm support 303 with respect to the end 341 of arm 340. V
The practical result of the structure just described is to facilitate swinging of movement of the arm support between the positions of FIGURES 16 and 17 or any infinite number of positions intermediate thereto.
With reference to the structure of the arm support 303, the same includes a U-shaped body portion 360, with the lower wall portion 361 thereof being connected to the support casting or plate 355, while the upper wall portion 362 is spaced therefrom in parallelism as shown in the drawings.
The remaining components of the top 300 relate to the covering pads that are provided for patient comfort and from an examination of FIGURES 16 and 17, it will be noted that a pad 370 is provided for use on the leg support 364, while pad 371 is provided in covering relationship to the hip support 301, as well as the chest and head support 302. Pads 372 and 373 are provided on the body portions 361 and 362 respectively for the purpose of providing a cushioned surface for the supported arms of the patient.
The unilateral top shown in FIGURES 16 through 24 inclusive, further includes a deformable loop member 380 that serves to support an ether or patient screen with the member 330 being connected at its opposed ends to the support member 302. Similar provisions have been made in the tops and 200 for use of such a flexible loop member which can be deformed by the surgon to the proper position for either screening the operative site from the patients view or for providing a sterile zone in the appropriate location.
THE PEDESTAL BASE 11 The pedestal base 11 is designed to be interchangeably used with any one of the three operating tops previously described, and accordingly the same will be described in detail at this point to show the characteristics of the operating components thereof so as to preface the description of the overall operation of the improved operating table 10.
Accordingly, and referring to FIGURE 25, the pedestal base is generally T -shaped in plan for maximum access by the surgeon. The T-shaped base housing 20 generally supports wheels 21, 21 that make the table shiftable over a surface area with locking of the wheels against movement being effectuated by foot control lever 22, while raising or lowering of the pedestal base 11 is effectuated by foot controls 23 and 24, with member 23 preferably being employed to elevate the unit while lever 24 is a release for returning the -unit to its normal height. Projecting upwardly from the T-shaped housing 20 is a main support column 25 that is telescopically received within an upper tubular column 26 to which the adaptor base is connected, with the member 26 being shifted relatively of the support column 25 by the known use of hydraulic pressure applied through the medium of the foot lever 23.
The adaptor .unit will be generally designated by the numeral 30 in connection with the ensuing description, and in this regard and referring to FIGURES 28 and 29, it will be noted that the adaptor 30, in fact, includes a fabricated housing or base portion 31 that is bored, as at 32, so as to be concentrically positioned over the projecting support shaft 33 that projects from the upper end 11 of the member 26, (FIGURE 29). In this fashion, the adaptor unit 30 can rotate relatively of the member 26 so as to, in effect, enable a full 360-degree turning action to be etfectuated by any operating top with respect to the base 11.
Control of the just described rotation is effectuated by the use of a locking shaft 34 that is threaded into a tapped bore 35 so as to have its projecting end 35a engageable with a reduced portion of shaft 33 to thereby eliminate rotational movement between the base 31 and the shaft 33 with conventional ball bearings 36, 36 facilitating the movement just described.
Projecting upwardly from the base portion 31 are main support arms 38 and 39 that are arranged in yoke-like fashion so as to support that portion of the adaptor 39 that is shiftable with respect to base 31 as will be de scribed. Accordingly, and referring again to FIGURES 28 and 29, it will be noted that the arms 38 and 39 serve to journal the opposed ends of a support shaft 43, with the support shaft 40, in turn, being journaled with the support arms 41, 42 and 43 that depend downwardly from the main support plate 44 that serves as the main point of connection with the individual tops 100, 200 and 300. In this regard and referring to FIGURE 29, the plate 44 further includes a wedge plate 45 that has tapered sides 45a and 45b that complementally engage the various tapered slides that have been previously described in connection with the individual tops 10%, 200 and 306.
Retention of the individual top in place on plate 45, is effectuated by the use of a locking pin 46 that is provided with a projecting pin 46a (FIGURES 28 and 31) that rides in a spiral groove 47a of a cylindrical housing 47, with housing 47 being carried by plate 44 in depending relationship and with pin 46 being eccentrically journalled in housing 47 so as to effectuate a camming action during movement to extended position. As shown in the drawings, the projecting end of the locking pin 46 is movable from a position beneath the surface of the plate 44- as shown in full lines in FIGURES 28 and 31, or to the elevated position shown in chain-dotted lines in FIGURE 31 with such shifting occurring upon rotation of the locking pin 46 by handle 46!). In this regard, it is to be understood that each top has an appropriate aperture for receiving the extended end of the locking pin 46 so as to effectuate locking of the top against transverse movement with respect to the mounting plate 44, with the camming action of the pin 46 serving to urge the top in question tighter into tighter contact with plate 45.
For the purpose of effectuating changes in elevation of the mounting plate 30, the depending arms 41 and 42 are shown apertured at their lower ends to receive opposed pins Stl, 50 that extend in opposed directions from a control block 51, with the control block 51 being threaded for engagement on a threaded shaft 52 and with the shaft 52 being rotatably supported by the base 31, as shown in FIGURE 28. The shaft 52 is connected by a universal coupling 53 to a turning shaft 54, with the turning shaft 54 being appropriately supported by a contoured extension 44a of the support plate 44 and with the shaft 54 further having its rotation controlled by an exposed control handle 55. As a result of the above structure, the support plate 44 which is pivotally supported on the support shaft 40 can be pivoted around this support shaft 40 upon rotation of the handle 55, with the pivoting movement, in fact, resulting from the shifting of the block 51 axially of the threaded shaft 52. Such movement controls the plane within which the support plate 44 lies so that Tredelenberg positioning can be achieved.
The extension 44a of support plate 44 further serves to support an auxiliary adjustment means generally indicated by the numeral 60, with the detailed construction of this control element being best shown and described in FIGURES 23 and 30 of the drawings.
Accordingly, and referring to FIGURE 30 first, the
appropriately contoured extension 44a includes a depending boss 61 that is bored and counter-bored as at 62 and 62 for the purpose of adjustably supporting an elongate shaft 64 that is intended to shift axially of the bore 62 as shown in FIGURE 30.
The shaft 64 is threaded as at 64:: and is further provided with an elongate slot 641) with these components being provided for the purpose of shifting the shaft 64 axially of the bore 62 as will now be described. To this end, a bevel gear 66 is shown positioned in surrounding relationship to the shaft 64 with the bevel gear being internally threaded for engagement with the thread 64:: of shaft 60, and with the bevel gear 66 being mounted on bearings 67 so as to be rotatably supported for meshing engagement with the bevel gear 68. The bevel gear 68 is mounted on a shaft 68a that is journalled with respect to the extension 44:: by bearings 68!), 68b with the rotation to the shaft 63:: being accomplished by handle 69. Rollers 78-, 76 are provided on the bevel gear support member '71 that is secured to the upper end of the shaft 64 while the boss 61 further includes a pin (not shown) that rides in the elongate groove 64/) of the shaft 64.
In this fashion, rotation of the handle 69 will cause a rotation of the bevel gears 68 and 66, with the rotation of the bevel gear 66 effectuating axially shifting of the shaft 64 due to the threaded engagement thereof with the thread 64a, with rotation of the shaft 64 being prevented by engagement of the pin (not shown) in slot 641).
Accordingly, the rollers 70, 70 can in effect, be freely moved upwardly and downwardly by merely rotating the handle 69.
Thus, from the foregoing, it will be seen that the handle 55 serves to control angular inclination of the supporting plate 44 with respect to the base housing 20 while the handle 69 serves to pivot the back chest or upper support portions relatively of the hip, abdomen, and lower side supports.
In this fashion, the upper and lower torso supports of any top can be moved relatively of each other or can be moved as a unit relatively of base housing 20.
As an accessory, FIGURE 1 also illustrates certain leg support elements that can be used in cases of obstetrical surgery.
In essence, these identical supports 190, 190, each include a block 191 having one end of a curved arm 192 attached thereto as by welding, with the free end of arm supporting a strap 193 that can be adjusted to receive the patients feet.
The blocks 191, 191 are each apertured as at 194, 194 so as to receive one or more attaching bolts 195, 195 that thread into tapped apertures 196, 196 provided on base 31 (see FIGURE 1) when the blocks 191, 191 are secured to opposite sides of the base 31 by bolts 196, 196 as described, the straps 193, 193 will accordingly receive the patients feet in such a fashion as to elevate the legs in the spread apart required for such operation. In such instance, the leg supports 103, 103 are normally swung apart to their condition of maximum separation.
OPERATION OF THE DEVICE While the overall operation of the device is believed somewhat apparent from the preceding detailed description, it is felt in order to undertake a short description with respect to the operation of the device in connection with each of the three operating tops above described.
Accordingly, the description of the operation will be undertaken with respect to the operation of the device when an individual top is positioned thereon.
A.Operatf0n during use of the supine top The operation of the device with the supine top 100 in position will be best understood from an examination of FIGURES 1 through 8 of the drawings, and in this regard, it will first be assumed that the top 100 has been operatively positioned with respect to the pedestal base by inserting the wedge block or plate 45 between the divergent guide blocks 130, 130 followed by locking of the 138 may be manually disengaged from the slot 132. At
this time, the flat surface 162 (FIGURE of the support plate 136 will come in contact with the rollers 70, 70 so that the articulated portions of the torso supports 301, .302 are now firmly positioned with respect to the pedestalbase 11. With preliminary positioning so achieved, the handle 55 may be operated to move the mounting plate .44 into a substantially horizontal plane and the handle 69 may also be manipulated so as to bring the back support 101 into preliminary relationship with the hip support 102. Additionally, the handle 14% may be manipulated so as to approximately locate the head support 105 in proper position.
When this initial adjustment has been accomplished, the patient may be transferred to the supine top 100, whereupon the leg supports 103, 103 as well as the arm supports 104, 104 may be preliminarily positioned so as to provide complete support for the patient. With the patient thus positioned, the surgeon may direct adjustment of the top 100 to the exact position required for the surgery involved. For example, the top 100 may first be positioned in either Tredelenberg or reverse Tredelenberg position if required by merely manipulating the handle 55.
In the event of an abdominal operation, the handle 69 may be manipulated to lower the back support 101 and thus, in effect, stretch the stomach by virtue of the pivotal movement of the back support 101 with respect to the -hip support 102. In the event of an obstetrical or gynecology operation, the leg supports 103, 103 may be moved around their pivot points (shaft 14) so as to be in the divergent position shown in chain-dotted lines in FIGURE 4 of the drawings, with this adjustment being elfectuated by mere lifting of the arm 120, followed by rotation of ber 151 relatively of either the back support 101 or the arm support 104, with this adjustment of the arm 151 being facilitated by dis-engagement of the teeth elements 153 and 157 thereof, with either of the teeth elements 152 or 158 (see FIGURE 7). The ether screen 180 may then be deformed to the appropriate position, with it being noted that the ether screen .is carried by appropriate apertures (not shown) that are provided preferably in the support plate 136.
The entire table top can be then rotated around the axis of member 26 by a mere backing off of thelocking member 3 as described in connection with FIGURE 29 so-that the patient may be positioned to give the op- ..erating surgeon maximum-accessibility to the operative :site.
It will be seen that the aforementioned adjustment features permit the patient to be positioned on his back so B.Operati0n during use of the prone top 200 The operation of the prone top200 will be best understood from an examination of FIGURES 9 through 15 of the drawings, and in this regard, attention is again directed to the fact that the prone position has two different types of leg supports that are capable of interchangeable use with regard to the abdominal support member 202.
Accordingly, and first assuming that the tapered ways 216, 216 have been secured in locked relationship with regard to the wedge plate of the pedestal base following by locking in place with shot pin 46, and further assuming that the handle and 69 have been operated to position the unit in the position of FIGURE 9, it is merely necessary that the patient be positioned on the top 200 in face down position, with the patient normally being initially positioned on the abdominal support 202 and the chest support 201, followed by adjustment of the leg supports 205, 205 to properly elevate the knees and accordingly relieve pressure that would otherwise be present on the abdomen. It further follows that the arm supports 203, 203 may be adjusted as shown in FIGURE 7 to properly support the patients arms and a similar adjustment may also be made of the head support 204 for the purpose of comfortably positioning the patients head.
At this point, in the case of rectal operations, the patients head can be lowered by use of handle 55 and the patients legs can then be moved outwardly apart so as to effectuate maximum exposure of the posterior area in the region of the operative site.
In instances where the leg supports 206, 206 are employed, it is merely necessary that these supports be inserted through the medium of having their pins 246, 246
inserted in the openings of the support arms 218, 218 with this condition of attachment being best shown in FIGURE 15 of the drawings.
Again and by manipulating either of the levers 55 or 69 and by further adjustment of the arm, leg and head supports, it will be seen that an infinite number of operative positions can be achieved with respect to a patient supported on the top in prone or facedown position.
Removal of the top 200 merely involves the unlocking of shot pin 46 followed by the sliding movement described previously to release the top 200 with respect to wedge plate 45.
It is contemplated that the head support 204 can be made integral with chest support 203 instead of being adjustable as described.
C.-Operati0n during use of the unilateral top 300 Referring now to FIGURES 16 through 24*for a description of the operation of the device with the unilateral .top 300 in position, it will first again be assumed that the hip support 301 has been operatively locked in mechanical engagement with the wedge plate 45 and shot pin 46 so as to have the top 300 operatively associated with the pedestal base 11 as shown in FIGURE 16 of the drawings, with it being noted that the rollers 70, 700i the control unit are .in engagement with the wear plate 331 so as to have the upper chest and head support 302 positioned as shown in FIGURES l8 and 19 of the drawings.
In the event that the patient will be lying on his left side, the arm supports 303 and leg support 304 will be positioned as shown in FIGURE 16. Conversely, if the patient to be operated upon is to lie on his right side, the arm support 303 and the leg support 304 will be positioned as shown in FIGURE 17.
In this regard, positioning of the arm support 303, 303 is facilitated by operation of the control lever .348 so as to permitrotationa'l'movement of the ends of the arm 340 with respect to support plates 330 and 356, with this con- :dition being shown and described in connection with FIGURES 20 and 21 of the drawings.
By like token, selective positioning of the leg supports 304, 304 is achieved merely bypassing the slots 324, 324 of the appropriate end plate 322 or 323 over the projecting T-shaped support arms 314, followed by engagement of the bolt head 326:: in cross channel 325, as shown in FIGURE 22 of the drawings.
Again and with reference to the operation of the unilateral top 300, the patients body can be elevated or lowcred at the head portion by use of handle 55, while the chest or upper side area can be adjusted with respect to the hip or lower torso area merely by movement of the handle 69 which effectuates relative pivotal movement between the members 301 and 302. Thus the torso support members 301 and 302 moved in unison by handle 55 or relatively of each othher by handle 69 as required.
It is, of course, to be understood that if desired, an adjustable head portion could be provided in lieu of the integral head support provided by the member 302.
Accordingly, it will be noted that an infinite number of operative positions is again achieved during use of the unilateral top 300 attached to the pedestal base shown and described above.
Removal of top 300 again merely necessitates unlocking of shot pin 46 followed by disengagement of ways 312, 312 from plate 45 by relative sliding movement therebetween.
CONCLUSION It will be seen from the foregoing that there has been provided a new and novel type of operating table that is characterized by the use of a plurailty of individual body supports that are respectively anatomically contoured to provide a contoured form fitting type of support for a human body in prone, supine and unilateral positions, with these individual body supports being selectively utilized on a common pedestal base 11 that will serve to position each top in an infinite number of operative positions.
It will be seen how the use of a plurality of tops assures the operating surgeon of a surgical posture that is unexcelled in safety, comfort and approach and further how the use of the individualized, anatomically designed tops eliminates the need for engineering compromises that were inherent in the single top operating tables of the prior art.
Further it has been shown how this concept has the additional advantage of providing maximum comfort to the patient during the operation so as to minimize postoperative effects from the operation that would otherwise be present during the recouperation period following the operation.
It has also been shown how the use of the principle of flexing an articulated contoured torso support serves to provide maximum patient comfort during the operative period, with undue strains on the supported torso being obviated as a result of the contoured support thereof together with minimal flexure that results from use of the proper anatomically designed top.
Further, and with regard to the preferred material to be employed, it is preferred that the tops be made of electically conductive plastic reinforced with fiberglass and contoured to anatomically support the various portions of the body, with the fiberglass being bonded or otherwise secured to light-weight castings such as aluminum, so as to provide a top of great strength and light weight. In practice, it has been found that individual tops made as above described normally weigh less than 30 pounds per top, so that the same are readily capable of being handled by a nurse in preparing for the operation in question.
It does follow, however, that the individual supporting elements of the top could be formed of reinforced metal that were either covered or padded with foam or other soft material so as to provide a contour type of support for the patient that would be substantially the equivalent of the contoured support described in connection with the preferred embodimenut of the invention.
Similarly, while a pedestal base of the type shown and described above is preferably employed in normal instances, it follows that the contoured tops could be utilized with other types of supporting elements that were either adjustable or fixed, depending upon the conditions involved, For example, in connection with field use by the armed services, it is contemplated that a tripod type of base could be provided for attachment to the guide means of the individual tops above described. Simple ratchet and pawl types of arrangement could be employed in this regard to effectuate an adjustment that would be effective in the field although not possessed of the same ease of operation as is present in connection with the preferred embodiment of the invention.
While a full and complete description of the invention has been set forth in accordance with the dictates of the patent statutes, it is to be understood that the invention is not intended to be limited to the specific embodiment herein shown.
Thus, while the preferred embodiment of the invention utilizes three tops, each made of fiberglass and aluminum castings and each designed for a specific position, it is to be understood that a greater or lesser number of tops made of different material and contoured for different operating positions could be employed.
Accordingly, modifications of the invention, such as change of material and contour, may be resorted to without departing from the spirit hereof or the scope of the appended claims.
