3,055,344- Patenteel Nov. 20, 1962 hee 3,065,344 SURGICAL OPERATING TABLES George It. Chervenka, St. Louis, Mo., assignor to Shampaineludustries, Inc., a corporation of Missouri Filed Oct. 12, 1959, Ser. No. 345,675 6 Claims. (Cl. 250-58) This invention relates in general to certain new and useful improvements in surgical operating tables and, more particularly, to an accessory top which can be utilized for adapting surgical operating tables for roentgenographic pictures.

Most surgical operating tables currently in use in hospitals, medical clinics, and the like, comprise a patientsupporting top member which consists of three transversely articulated sections commonly referred to as the backsection, seat-section, and leg-section. In addition, it is usual practice to supply such operating tables with a removable and transversely articulated head-rest. These various sections ordinarily are employed to support the patient in a prone position. Thus, the patients head is usually supported by the head-rest, the patients shoulders and chest are usually supported by the back-section, tne lower portion of the patients abdomen, including the hips and buttocks, are usually supported by the seat-section, and the lower portion of the patients body, including the thighs, knees, legs, and feet, are usually supported by the leg-section. Moreover, during the course of most types of surgical procedure, these various sections are positioned at different angles, so that the various portions of the patients body will be held in some prescribed relationship which is most suited to the particular surgical procedure contemplated. In addition to this, it is often necessary, during the course of a surgical operation, to change these various positions. For these reasons, the articulation of the various sections forming the top of the surgical table is an important aspect of the mechanism and cannot be impeded in any way by accessory devices.

On the other hand, it is often necessary, during the course of a surgical procedure, to take an Xray photograph of some particular portion of the patients body. For example, in an exploratory operation for the location and removal of a foreign object, the surgeon might find it desirable to have an X-ray photograph if the object has shifted its position since the pre-operative photographs were taken. Similarly, in orthopedic surgery it is often convenient to be able to take an X-ray photograph during the course of the operation. There are many other situations of similar nature.

In small-er institutions, such as medical clinics, small hospitals, and the like, a great deal of the equipment must have a very broad range of utility, inasmuch as such institutions do not have the space or funds for a large number of highly specialized pieces of equipment. In such instances, it is sometimes desirable to use the operating table for taking X-rays. Even in large institutions which have extensive radiological facilities, there are occasions when the radiologist would like to take a particular diagnostic X-ray with the patients body held in some particular position or positions, and such positions can best be obtained on a surgical operating table.

It is, therefore, the primary object of the present invention to provide means by which it becomes possible to take X-ray pictures of any portion of a patients body while the patient is supported upon a surgical operating table.

It is another object of the present invention to provide auxiliary or accessory means for fitting up a surgical operating table so that X-ray pictures may be taken thereon whenever need arises, either during the course of a surgical operation or when the particular X-ray photograph requires that the various part of a patients body be held in some predetermined relative position.

It is also an object of the present invention to provide accessory means of the type stated which are economical in construction, but are nevertheless rugged and durable.

It is a further object of the present invention to provide accessory means of the type stated which can be applied to, and removed from, a surgical operating table very quickly, without the use of tools, and without requiring the services of a skilled mechanic or specially trained technician.

With the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combination of parts presently described and pointed out in the claims.

Referring now in more detail and by reference characters to the drawings, which illustrate a preferred embodiment of the present invention, A generally designates a surgical operating table which includes a hydraulic pistontype pedestal 1 and top 2 provided with transversely articulated leg, seat, and back sections 3, a, 5, respectively. Removably mounted upon the head-end of the back-section 5 is an articulated head-rest 6. The legsection 3 is conventionally provided along both of its lat eral margins with side rails 7, which are held in place by rather large-diameter horizontal studs 8, 9. The seatsection 4 is simifarly provided along both of its lateral margins with side rails 10, which are held in place by large-diameter horizontal studs 11, 12. Finally, the baclo section is provided along both of its lateral margins with side rails 13, which are held in place by large-diameter horizontal studs 14, 15. The top 2 is provided with rearwardly extending arms 16, 17, which operatively contain the manipulative control handles l8, 19, respectively, by which the various movements and positions of the table can be achieved. Although the present invention is ap- 3 plicable to any type of surgical operating table, the ticular table which is schematically shown in the drawings is of the type more fully described in United States Letters latent No. 2,416,410 and United States Letters Patout No. 2,647,026, respectively issued February 27, 1947, and luly 28, 1953, to R. Shampaine, and is, therefore, only described herein in general terms.

Provided for removable disposition upon the leg-section 3 is an accesory top member T which consists of a substantially rectilinear top plate 2% fabricated from a strong, heavy sheet of X-ray permeable .lnctcullcil. A number of materials, such as three-quarter inch plywood, pressed cellulosic hardboard, resin-bonded fabrics, and the like, have been found satisfactory for purposes of the present invention. Preferably, though not necessarily, the corners of the top plate it; are rounded for reasons of convenience and safety. Bolted upon u er of the top plate Ell adjacent the four corner thereof are four short leg members 21, each of which is provided in one of its outwardly presented faces with a female snap-fastener element or so-called dot for engagement with companion-shaped male snap-fastener elements 23 which are rigidly mounted in the lower ends of attachment straps 2d stitched upon or otherwise secured to the under face of a resilient pad 25. The pad is conventionally constructed with an outerenvelope or covering made of suitable synthetic sheeting, rubber sheeting, or similar water-proof sterilizab re material and is, therefore, not described in specific detail herein.

Also bolted or otherwise rigidly secured upon and de pending from the under face of the top plate 259 adjacent the forward two corners thereof are depending attachment brackets 26 formed preferably of metal bar-stock and having a transverse thickness slightly smaller than the transverse distance between the lateral faces of the leg section 3 and the inwardly presented faces of the side rails 7 so as to fit easily therebetween. On their downwardly presented margins, the attachment brackets 26 are provided with upwardly extending slots 2J7 having semicircular top margins 23 and vertical side in 'ns 2% spaced so as to lit snugly, but, nevertheless upon, and embracingly around, the studs 8.

A second accesory top member T is also provided which is identical in every respect with the previously described accessory top member T and is adapted for similar disposition upon the back-section Provided for removable disposition upon the seat-section 2 is an accessory top member T which consists of a rectilinear top plate 36 likewise fabricated from a strong, heavy sheet of Xray permeable material. Preferably, though not necessarily, the corners of the top plate 38 are also rounded for reasons of convenience and safety. Bolted upon the under face of the top plate Sil adjacent the four corners thereof are four short leg members 31, each of which is provided in one of its outwardly presented faces with a female snap-fastener element or socalled dot 32 for engagement with companion-shaped male snap-fastener elements 33 which are r' idly mounted in the lower ends of attachment straps stitched upon or otherwise secured to the underface of a resilient pad 35. The pad 35 is conventionally constructed with an outer envelope or covering made of suitable synthetic sheeting, rubber sheeting, or similar water-proof sterilizable material and is, therefore, not described in specific detail herein.

Also bolted or otherwise rigidly secured upon and depending from the underface of the top plate 38' adjacent the forward two corners thereof are depending attachment brackets 36 formed preferably of Metal bar-stock and having a transverse thickness slightly smaller than the transverse distance between the lateral faces of the seatsection 4 and the inwardly presented faces of the side rails ill so as to fit easily therebetween. The attachment brackets 36 are integrally provided with extension por- 4 tions 37 which project in direction of the head-end of the table A so as to give the attachment brackets 36 substantially greater width in this direction. Formed in extending upwardly from the downwardly presented margins of the attachment brackets 36 and the integral extension portions 37 two upwardly extending slots 33, haying semi-circular top margins as, at, and side margins 42, 4:3, 44, 45, respectively. The margins 42, 43, and 45, are respectively spaced such a manner as y it snugly, but, nevertheless removably, down upon the studs ll. it should be noted in this connection that by ionally engaging either the slots 38, or in the studs 1., it is possible to vary the position of the top member T lengthwise with respect to the seat-section 4.

Provided for disposition upon the head-rest section is accessory top member T co uprising an X-ray permetop plate 46 of suitable rectilinear shape and size. olted or otherwise rigidly mounted upon the under face of the top plate 46 along the forward and rearward transverse margins thereof are depending hanger frames d7, each including inwardly turned horizontal top lips 4-3, depending vertical legs 4-9, and a relatively long horizontal bight member 5b. Rigidly secured to, and supported by, the hanger frames d7 is a bolt plate 51 integrally provided at its opposite transverse margins with depending vertical side plates 52., 53, which are, in turn, integrally provided at their lower margins with horizontal slideforming flanges d4, 55, which are, in turn, integrally provided with short upstanding vertical lips 56, 57, all of which are sized and spaced by slidably fitting around the lateral margins of the head-rest 6. Furthermore, the side plates 52, 53 are provided With female snap-fastener elements 53 for engagement with matching male snapfastener elements 59, which are mounted in the lower ends of attachment straps 6b which are stitched or otherwise suitably secured upon the under faces of pads 61, the latter being substantially similar in construction and function with the previously described pads 25, 35.

Also provided for use with the accessory top members T T T T is a cassette handling-frame F consisting of a plate-like sheet 62 of metal or other suitable ri,.id material of generally rectilinear configuration having three rectilinearly intersecting margins 63, 64, 65, and being diagonally cropped across two outer corners in the provision of angular margins 66, 67, and a short cross margin 63. Formed integrally with and extending upwardly from the three rectilinearly intersecting margins 63, M, and 65, are three connected flanges 69, '70, and '71. Similarly formed with and extending upwardly from the cross margin 63 is a short separate flange 72, all as best seen in FIG. 7. Centrally secured to flange 70 and extending outwardly therefrom is a handle h provided on its upper surface with a suitable series of graduations of a type conventionally used by X-ray technicians in connection with the placement of a cassette in proper position beneath the patient. The frame F is of such shape and proportion as to fit conformably around a standard X-ray cassette and is of such vertical height and width as to slide between the under faces of the top plates Ztl, 3d, and 46, as the case may be. Moreover, the frame F can be slid in transversely from either the right or the lefthand side of the operating table or can be slid in longitudinally from either end to place an X-ray cassette beneath either one of the accessory top members T T T T The frame also may be slipped longitudinally in from the head-end of the head-rest 6 so as to position an X- ray cassette beneath the top plate as of the accessory top member T In setting up the surgical operating table A for any sort of surgical procedure wherein an X-ray might possibly be desirable or necessary, the several accessory top members T T T T can be quickly and conveniently installed either with or without pads 25, 35, 61, as may be desired, and the surgical operating table A may then be draped in the usual manner. If, during the course of the surgical procedure, it may be desirable or necessary to have an X-ray of any particular portion of the patients body, an X-ray cassette can be placed within the frame F and slipped into the desired position without disturbing the patient or otherwise interfering with the position of the surgical operating table A. A portable X-ray unit of any conventional type can then be moved into position above the patient and the X-ray exposure made in the usual manner. Once the X-ray plate within the cassette has been exposed, it can be quickly and conveniently removed and taken to a development laboratory, again without disturbing the patient or the position of the surgical operating table A.

It should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the surgical operating tables may be made and substituted for those herein shown and de scribed without departing from the nature and principle of my invention.
