TABLE SUPPORTED ABDOMINAL RETRACTOR Filed April 29, 1950 3 Sheets-Sheet 3 4 INVENTOR. DAV/0 PSM/TH ATTX Patented Apr. 22, 1952 OFFICE TABLE SUPPORTED ABDOMINAL RETRACTOR David P. Smith, Meriden, Conn. Application April 29, 1950, Serial No. 158,981 c Claims. (o1.12s-20) This invention relates to surgical retractors and more particularly to an abdominal retractor which comprises means for firmly supporting a plurality of independently adjustable retracting elements above an operating table so as to hold the edges of a wound and the viscera or other organs away from the field of operation.
One object of this invention is to provide a retractor ofthe above nature in which the retracting elements do not depend upon each other or upon their engagement with the patient for their proper support, thus avoiding movement of the retracting elements which might cause shock tothe patient and which would be a source of annoyance to the surgeon.
Another object is to provide a retractor of the above nature which may be employed to retract any part of the wound or the organs therein in one direction without requiring the retraction of another part in the opposite direction.
Another object is to provide a retractor of the above nature in which, if desired, the retracting elements may all be adjusted as a unit in both horizontal and vertical directions.
Another object is to provide a retractor of the above nature in which each of the retracting elements may be easily adjusted either radially or circumferentially of the wound at any time without disturbing the positions of any of the other retracting elements.
Another object is to provide a retractor of the above nature which may be readily installed, adjusted, and removed, and which will not be likely to change its adjustment accidentally, whereby the retractor will require a minimum of attention from the operating surgeon and the minimum number of assistants will be required.
A further object is to provide a retractor of the above nature which will be simple in construction, inexpensive to manufacture, easy to install and manipulate having universal adjustment, and very efficient and durable in use.
With these and other objects in view there has been illustrated on the accompanying drawing one form in which the invention may conveniently be embodied in practice. e
The invention herein disclosed constitutes an improvement in the retractor disclosed in my copending application entitled Self-Supporting Surgical Retractor, S. N 92,602, now Patent Number 2,586,488 granted February 19, 1952, filed May 11, 1949, in respect to the hinged side supporting arms and the circumferential adjustability of the retractor elements, not shown in said copending application.
In the drawing,
Fig. 1 is a perspective view of the improved retractor.
Fig. 2 is a plan view of the same as it would appear when attached to the side rails of an operating table.
Fig. 3 is a front view of the same, showing the retractor as it would appear when the retracting elements are removed, and showing the side rail clamps in cross-section.
Fig. 4 is a fragmentary view, on an enlarged scale, taken on the line 4-4 of Fig. 2, showing the manner in which the side arms are connected to the ring.
V Fig. 5 is a partial perspective view showing an end portion of one of the side arms and the pivot pin therein.
Fig. 6 is a cross-sectional view on an enlarged scale, taken substantially on the line 66 of Fig. 2, showing the manner in which the retracting elements are attached to the supporting ring.
- Fig. '7 is a fragmentary perspective view of the same.
Fig. 8 is a perspective view showing one of the slotted brackets for attaching the clamping elements to the supporting ring.
Referring now to the drawing, in which like reference numerals denote corresponding parts throughout the several views, the improved retractor comprises a supporting ring [0 which is of flat circular shape and of uniform rectangular cross-section. In order to support the ring I0, provision is made of a pair of outwardly-extending side arms ll, I2, the inner end of each of said side arms being formed with a notch l3 in which the enlarged flat-sided base M of a pivot pin [5 is swingably secured by means of a horizontal cross pin it.
The lower surface of the supporting ring II] is provided at diametrically opposite points with a pair of lugs I! which are apertured in a direction radially of said ring and attached thereto by means of rivets Hi. The lugs l! are adapted to receive the pivot pins l5 which may be firmly secured therein by thumb screws [8. l
The side arms II l 2 are curved outwardly and downwardly from the pivot pins l5 and are adapted to be attached to the side rails 20, 2| of an operating table 22 by means of a pair of C-shaped clamps 23, 24. The clamps 23 24 are so shaped as to be freely slidable in a longitudinal direction upon the side rails 20, 2| and are vertically apertured in such a manner that the side arms ll, l2 may be adjustably held therein and securely clamped against the outer faces of the side rails 20, 2| by thumb screws 25.
In order to hold a wound open and retain the internal organs of the body away from the field of operation, provision is made of a plurality of angular retracting elements 26, each of which comprises a longitudinally slotted horizontal upper base portion or arm 21, and a depending concave hook portion 28 at one end of said arm. Each of the retracting elements 26 is provided with a U-shaped bracket 29 in the form of a flat rectangular block having a deep rectangular slot 30 in one edge thereof, and athreaded stud 3| attached to its upper surface.
The stud 3| extends upwardly through the slot in the retractor arm 21 and is provided with a knurled thumb nut 32, whereby each of the retracting elements 26 may be adjustably clamped to its respective U-shaped bracket 29.
The slots 30 are adaptedto receive the outer edge of the ring H] and are so proportioned that the brackets 29 will be slidable circumferentially on said ring. Further, the slots 36 have divergent outer end surfaces 33 which will facilitate the application of the brackets to said ring Ill.
In order to prevent any substantial turning movement of the U-shaped brackets with respect to the retracting elements 26, the upper surface of each of said brackets is provided with a short upstanding pin 34 engaged in the slot of the arm 27 adjacent the threaded stud 3|.
Manner of use In use, the retractor herein disclosed will be applied to the operating table 22 after the patient P has first been prepared for the operation and is resting on said table in the position indicated in dotted lines in Fig. 3.
The first step in applying the retractor will be to insert the lower ends of the pair of side arms I, I2 into the C-shaped clamps 23, 24 which embrace the side rails 26, 2|, after which the thumbscrews 25 will be tightened so as to clamp said side arms securely against said rails.
It will be noted that the curvature of the side arms |2 will permit the supporting ring ||l to be swung either to the right or to the left prior to the tightening of the thumb screws 25, this movement being obtained by inserting the side arms l2 through the clamps 23, 24 in varying degrees.
Moreover, the vertical apertures in the clamps 23, 24 provide sufiicient clearance to permit the curved side arms I I, I2 to be slid equal distances therein for adjusting the supporting ring In in a vertical direction, after which the thumb screws 25 may be tightened so as to hold the retractor securely at the desired elevated position. Lateral tilting adjustment of the supporting ring l may, of course, be obtained by moving either one of the side arms l2 vertically in its respective clamp 23 or 24, whereas tilting of the ring II] in a direction longitudinally of the table 22 may be permitted by the manipulation of the thumb screws I9.-
Thus, the supporting ring In may be easily adjusted laterally, longitudinally, and vertically, and tilted either laterally or longitudinally so that it will occupy the precise position desired by the surgeon, in which position it will be firmly held by the thumb screws I9 and 25.
After an incision or opening has been made in the patients body, the retracting elements 26 will be inserted in the wound and applied to the ring H1 in the positions desired, the brackets 29 being slipped over the outer edge of the ring l6 so that the arms 21 of said retracting elements are disposed above said ring. The slotted formation of the retracting element arms 2'! will now permit each element to be slid outwardly so as to provide the desired degree of retraction, after which the respective thumb nuts 32 will be tightened.
The upstanding pins 34 on the brackets 29 will, of course, prevent undesirable rotation of said brackets during manipulation of the thumb nuts 32, and will aid in maintaining the slotted arms 21 and brackets 29 in proper relationship at all times.
Inasmuch as the brackets 29 are slidable around the periphery of the supporting ring H), the retracting elements 26 may be adjusted laterally in order to afford the desired support to the organs or to the edges of the open wound.
It will be understood that any of the retracting elements 26 may be applied, removed, or adjusted at any time during the course of the operation, and if desired, may be replaced with retracting elements which are longer or shorter, or of a different type, thus filling the needs of the moment.
It will be noted that the invention herein disclosed provides a means whereby each of the retracting elements may be independently adjusted and held in a definite position withv relation to the operation table. Further, the retracting elements cannot accidentally change their positions and the force exerted by one retracting element will be independent of the force exerted by any of the other retracting elements. Moreover, the patient will be spared the shocks which might be caused by accidental movement of a retractor in contact with the peritoneum which frequently occurred when the retracting elements were held by an assistant.
One advantage of the invention herein disclosed is that each of the retracting elements may have a substantially universal adjustment with respect to the operating table, while avoiding any changes of position or adjustment excepting as desired by the surgeon.
When the retractor is no longer needed, it may be readily removed from the clamps 23, 24 after first loosening the thumbscrews 25. The side arms |2 may then be swung about the crosspins I6 and folded under the supporting ring |0 so that the retractor will have a compact form which may be readily inserted into an autoclave for sterilization.
Inasmuch as the retractor may be compactly folded, it will ordinarily be unnecessary to detach the side arms I I, I2 from the supporting ring H1, or to loosen the thumbscrews l9 excepting for purposes of adjustment. While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosure but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims.
Having thus fully described the invention, what is claimed as new and for which it is desired to secure Letters Patent, is:
1. In a surgical retractor, a continuous, integral, circular supporting ring, a plurality of retracting elements movably mounted upon said ring, a pair of side arms attached by fiexible joints to opposite portions of said ring, anda pair of adjustable clamps on said side arms for securing said side arms to a support.
