9 Claims. (01. 128-346) My invention relates to a new and useful improvement in a surgical instrument adapted for use particularly in circumcising.

This application constitutes a continuation of my application Serial Number 727,103 filed February 7, 1947, now abandoned.

It is an object of the present invention to provide in instruments of this class whereby a surgeon may easily and quickly clamp the foreskin in position for performing the operation.

Another object of the invention is the provision of a device of this class whereby the foreskin will remain clamped after the operation to prevent excessive bleeding.

Another object of the invention is the provision of a clamping mechanism in a device of this class which may be easily and quickly moved into position for clamping the foreskin after the proper adjustments of the instrument with the foreskin located thereon have been made and whereby the clamp having the foreskin located thereon is held to prevent rotation.

Another object of the invention is the provision of a device of this class which will be simpl in structure, economical of manufacture, durable, light, compact, and easily and quickly operated.

Other objects will appear hereinafter.

It is recognized that various modifications and changes may be made in the detail of structure illustrated without departing from the invention itself and it is intended that such shall be embraced within the scope of the claims which form a part hereof.

Forming a part of this specification are drawings in which:

Fig. 1 is a top plan view of the invention,

Fig. 2 is a side elevational view of the invention with parts broken away and parts shown in section,

Fig. 3 is an enlarged cross-sectional view taken on line 33 of Fig. 2,

Fig. 4 is a sectional view taken on line 4-4 of Fig. 3,

Fig. 5 is a sectional view taken on line 5-5 of Fig. 3,

Fig. 6 is a side elevational view of the invention in collapsed form and slightly reduced in size.

As shown in the drawings, the invention comprises a base l2 projecting diametrically outwardly from which at opposite sides thereof are the arms l3 and I4 whose ends are turned upwardly as at l5. The base I2 is formed circular and has a threaded hole l6 therethrough. Adapted to seat upon the face of the base I: is a disc 2 I8 having the downwardly extended neck H for threading into the threaded hole IS. A tapered opening I9 is formed through the neck l1. At the narrowest diameter of the opening IS the sides flare outwardly to provide a seat 20 on the face of the disc l8.

Legs 2| and 21a are pivotally secured at one of their ends to the up-turned ends ,I 5 by means of a screw 2|b. The opposite ends of these legs 2| and 2|a are connected by the cross-head 23. Fixedly secured in the cross-head 23 is a sleeve 24. Threaded through the sleeve 24 is a screw 25 having the knurled knob 26 on its upper end and provided on its lower end with the cavity 2'! in which the end ofthe clamping rod 28 may engage. The lower end of the rod 28 is flared outwardly, as at 29, to form a head about which the foreskin 3| is drawn upwardly to embrace the lower end of the rod 28. The rod 28 is provided with a passage 32 which communicates with the lateral passage 33 which, in turn, communicates with the recess 34 formed in the end of the rod. The rod 28 is provided with flat sides 35 adapted to engage in the pocket 36 formed in the cross-member 31 which is secured between and to the legs 2| and 2 la.

Pivotally secured by screws 38 adjacent the upper end of the legs 2| and 2|a are the arms 39 and 40 of the channel link 4|. The end of the channel link 4| is pivotally connected by pin 43 to one end of the toggle link 42, its opposite end connected by pin 44 to the lugs 45 secured on the plate 46 that extends rearwardly of the arms I3 and I4. Carried by the channel link 4| is the pin 48 against which is adapted to rest the band 41 which, when moved against the pin 43, serves to lock the toggle link 42 with the channel link 4| against pivotal movement.

In the use of the instrument, the legs 12: and 2|a would be moved to the position shown in Fig. 6. The surgeon would then draw the foreskin 3| through the opening l9 so as to embrace the lower end of the rod 28 which would be seated upon the seat 20 so that the foreskin is pressed by the end 30 against the edges of the opening. The legs 2| and 2|a would then be swung upwardly and the toggle links 4| and 42 when straightened out and locked in alignment by the [band 41 would locate the head 23 directly over the upper end of the rod 28. As the legs 2| and 2 la are swung upwardly, the rod 20 would enter into the pocket 36 to further locate its alignment with the screw 25. The flat sides 35 of the rod engaging the straight sides of the pocket 36 will prevent the rod from rotating as the surgeon, upon rotating the screw 25, would force the rod 28 downwardly so as to tightly clamp the foreskin between the end it and the seat 20. By holding the rod 28 against rotation, the foreskin 3| will not become displaced on the stem nor twisted thereon. The cutting instrument-isrested upon the face'of thedisc and broughtinto contact with the foreskin to effect the necessary severing, as the foreskin is not twisted or bunched, there will be effected a clean, even cutting. After the circumcision has been effected the remaining foreskin would still remain clamped tightly by the end of-therod 23 upon the seat 28 so that bleeding wouldbe practically eliminated. After the-'operatiom the surh geon would unthread the screw '2-5untilth'e stem 28 was disengaged whereupon the structure may be collapsed into the position shown in Fig. 6, and the rod 28 easily removed.

Experience has shownthat with-a clamping device 'of this typ'eg'the" operation may be. quickly an'd'ea'sily performed in a'mo'st efficient manner with .a minimuma'mount of bleeding. Experience hasalso shown that by having the parts swingablyoonnec'ted, as indicated, the operator,

when beginning the operation, may-move quickly as all of the' parts'arereadyfor movement into operativezposition.

Further, by having the'disc i8 threadably attachedinto the base' I2 it can easily and readily be changedwith a 'disclhaving a larger or smaller diameter bore 19- so-that the device is quickly altered and readied for useto provide the proper and requisite bore diameter necessary for drawing the foreskin of aperson to be circumcised. This disc l-8 may-be said to'be a presser. plate which is detachably mounted in the'threaded opening of the base.
