E. N. TURKUS RETRACTOR FOR AMPUTATION PURPOSES Filed April 9, 1924 INVENTOR B N. Tbrkps Patented Aug. 18, 1925.

UNITED STATES EDWARD NEWTON TUEKUS, OF BROOKLYN, NEW YORK.

BETRACTOR FOR AMIUTA'IION PURPOSES.

Application filed April 9,

To all whom it may concern:

Be it known that I, EDWARD NEWTON TURKUS, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Retractors for Amputation Purposes, of which the following is a specification.

This invention relates to surgical retracrtors adapted particularly for use in the amputation of the legs or arms of the body, an object of the invention being to provide an improved instrument of this character which will 'be relatively simple in construc tion, easily and conveniently manipulated by the surgeon, readily adjusted over the bone of the member to be amputated, and which may be employed to effectually retract or hold back the flesh from the point where the bone is to be sawed.

A further object of this invention is to provide an improved retractor for amputation purposes comprising a pair of relatively swinging plates or jaws correspondingly notched at adjacent edges thereof and so constructed that they may be swung into position to embrace the bone, readily adjusted to conform to the size of the bone, or to embrace the bones of the forearm, and wherein the device is provided with handles so constructed in an improved manner as to enable the instrument to be manipulated readily and efliciently.

Other objects of this invention will appear in the following description and appended claims thereof, reference bein had to the accompanying drawings forming a part of this specification wherein like ref erence characters indicate correspondingparts in the several views and wherein Fig. 1 is a plan view illustrating an embodiment of my invention; Fig. 2 is a side view of the construction shown in Fig. 1; Fig. 3 is a view illustrating the device in operative position; Fig. 1- is a perspective view of one of the pivoted jaws; and Fig. 5 is a fragmentary section of the jaw shown in Fig. 4, illustrating the fastening devices.

Before explaining in detail the present improvement and mode of operation thereof it is desired to have it understood that the invention is not limited to the details of construction and arrangement of parts which are illustrated in the accompanying drawings, since the invention is capable of 1924. Serial No. 705,207.

other embodiments, and that the phraseology which is employed is for the purpose of description and not of limitation.

In its present preferred form herein shown and described the present invention comprises a pair of metal plates or members 9 and 10 which are swingingly connected together in overlapping relation and so constructed that they may be swung into position to embrace the bone of the limb to be amputated. As illustrated each of the members or plates 9 and 10 may be correspondingly semi-circular in shape, forming when pivoted together at one end, an elongated or substantially semi-circular opening 11 for the reception of the bone. These plates are thus substantially U-shaped in construction, and owing to their overlapping meeting ends the bone-receivingopening can be varied in its diameter to fit different sizes of limb bones.

The plates 9 and 10 are pivotally connected together in overlapping relation, one end 13 of the plate 10 being superimposed upon the corresponding end 14 of the plate 9, and pivoted together at 15. The plates 9 and 10 are thus constructed to form swinging jaws which may be readily swung toward and from each other. It will be seen that when the plates are shifted together, the end 16 of the plate 10 will be shifted to overlap the end 17 of the plate 9, and in the present construction means is provided for adjusting the ends 16 and 17 together in different positions. A curved open slot 18 is formed in the free end 16 of the plate or jaw 10, and the plate 9 is provided adjacent to the free end thereof with a projecting pin 19 which is threaded to receive a wing nut 20 which is preferably held in position against removal from the pin 19 by upsetting the outer end of the pin. The free end 17 of the plate or jaw 9 is also provided with a pin 21 having a squared portion 21 and a relatively wide flat head 22. From this construction it will be seen that upon swinging the jaws 9 and 10 together, the pin 19 and the squared portion 21 of the pin 21 will travel into the curved slot- 18, the head 22 of the pin 21 overlapping the edges of the slot and bearing thereagainst.

The pins 19 and 21 may be held in different positions within the slot 18 by screwing down the wing nut- 20 against the edges AU jLlLLL may by inse 20. The hanele is thus L e plate or 9 and may be swung in 01 posite directions either side of the plate or w. A similar handle bent to f -n on .y resilie t or desired they may be gr and the intermidiate por ti gether or contracted when grn Jen erecy 1 L prevent'ng the hands from sl'pp'ng when pulling on the handles.

In the operation of the present invention is vill be understood that the usual incisions are made in the flesh of the limb to be ainputated so as to expose the bone as shown diagrammatically in Fig. 3, and permit the flesh to be laid back away from the point where the saw cut is to be made. The handles 2e and 28 are thereupon grasped after loosening the wing nut 20, and the jaws 9 and 10 swung apart sufficiently to permit the same to be inserted over the bone 39. By manipulating the handles the jaws are swung together to cause the pin 19 and the headed pin 21 to pass into the slot 18. The jaws are swung together in overlapping relation until the communicating notches 11 and 12 conform loosely to the shape of the bone. Thereupon the wing nut 20 is tightened so as to clamp the ends 16 and 17 of the jaws firmly together in fixed position. The handles 24: and 28 are then grasped by the surgeon and by pulling rearwardly onthese handles the flesh, as indicated at 30. is retracted or held back from the point 31 where thebone is to be sawed. It will be noted that the plates 9 and 10 are concave on the inside, which construction enables the flesh to be retracted more readily. By virtue of the elongated slots or recesses 11 or 12 and the overlapping of one plate 9 upon the other, it is possible to adjust the retractor to any size bone. Furthermore where amputation of the forearm is to be effected the jaws may be readily adjustedto permit the communicating notches or recesses 11 and 12 to embrace both bones of the forearm. The

adjustment of the free ends of the jaws by means of the pin and slot connection is particularly advantageous since the entire device may be controlled merely by grasping and manipulating the handles 2 1 and 28., with the exception of tightening or loosening the wing nut 20 which is in such position exteriorly of the retractor as to permit it to be conveniently and quickly manipulated by the surgeon. Furthermore it will be observed that by virtue of the fact that the exterior face of the retractor is convex in shape the projecting wing nut 20 will be located entirely out of the way of the saw wnen making the saw cut close to the central part of the retractor as indicated in Fig. 3.

As hereinbefore stated the retractor is preferably formed from metallic plates, and

in order to reduce materially the weight of the device these plates are preferably provideo. with perforations 32. It will be also noted from the foregoing construction'that connecting together the jaws9 and 10 in ex rlapping relation, and by releasably connecting the free ends of the jaws at two points by means of the headed pin 21 and the wing nut 20, the resistance strength of the retractor is considerably increased, and

any tendency of the jaws to separate where considerable leverage is placed thereon is prevented.

it is to be understood that by describing in detail herein any particular form, structure or arrangement, it is not intended to limit the invention beyond the terms ofthe several claims or the requirements of the prior art.
