SURGICAL INSTRUMENT Filed June 7, 1946 l/YIC Yfd? aw/y at IMP/ye? Patented Oct. 11, 1949 UNITED STATES ATENT QFFiCE 4 Claims. I

My invention relates to a new and useful improvement in a surgical instrument adapted for use particularly in circumcising.

It is an object of the present invention to provide an instrument 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 in 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.

Another object of the invention is the provision of a device of this class which will be simple in structure, economical to manufacture, durable, light, compact and easily and quickl 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 a part broken away and a part shown in section,

Fig. 3 is a front elevational view of the invention with parts broken away and parts shown in section,

Fig. 4 is a view taken on line 44 of Fig. 3,

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

Fig. 6 is a fragmentary sectional view taken on line E5 of Fig. 2,

Fig. '7 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. The base 12 is formed cupshaped to provide the recess l5, the face thereof having the inclined surface IS on its inner side and the inclined surface I! on its outer side and provided with an opening [8 formed therethrough.

Secured at one of their ends are the trunnions l3 and I4 and projecting outwardly therefrom are the rods 19 and 20 which are secured at their opposite ends to the block 2|. Projecting upwardly from this block 21 is a lug 22 to which is pivotally connected one end of the toggle link 24 the opposite end of which engages in the channel link 25 and is pivotally connected thereto. The upper end of the channel link 25 is pivotally connected to a tongue 26 projecting outwardly from a cross-head 30. This link 25 is cut away as at 2'! so that the device may be collapsed from the position shown in Fig. 2, to the position shown in Fig. 7. Secured to the crosshead so at one of their ends are the legs 28 and 29 the lower ends of which are pivotally connected by means of the screw 3! to the arms l3 and It.

Threaded through the cross-head 30 is the screw 32having the knurled knob 33 on its upper end and provided on its lower end with the cavity 34 in which the end of the clamping rod 35 may engage. Formed on the rod 35 adjacent its lower end is a peripheral head or projection 36 which provides a head about which the foreskin 3? is drawn to embrace the lower end of the r0d'35. This rod 35 is provided with a passage 38 com" municating with the lateral passage 39 which in turn communicates with the recess All formed in the end of the rod.

In the use of the instrument the legs 28 and 29 would be moved to the position shown in Fig. 7. The surgeon would then draw the foreskin 3! through the opening 1'8 so as to embrace the lower end of the rod 35 which would be projected through the opening I8 so as to press the foreskin against the edges of the opening H3. The legs 28 and 29 would then be swung upwardly and the toggle links 25 and 24, when straightened out would locate the head 38 directly over the upper end of the rod 35. The surgeon then by rotating the screw 32 would force the rod 35 downwardly so as to tightly clamp the foreskin between the edge of the opening l8 and the rib or bead 36. The cutting instrument would then be rested upon the inclined surface I! and brought into contact with the foreskin to effect the necessary severing. After the circumcision has been effected the remaining foreskin would still remain clamped tightly between the edge of the opening it and the bead or rib 36 so that bleeding would be practically eliminated. By having the surface I? inclined upwardly towards the center the cutting operation is considerably facilitated. After the operation the surgeon would unthread the screw or stud 32 until the stem 35 was disengaged whereupon the structure may be collapsed into the position shown in Fig. 7 and the rod 35 easily removed.

Experience has shown that with a clamping device of this type the operation may be quickly and easily performed in a most eflicient manner with a minimum amount of bleeding. Experience 'has also shown that by having the parts swingably connected as indicated the operator, when beginning the operation, may move quickly as all of the parts are ready for movement into operative position.

The subject matter of this application, substantially, is disclosed in my copending later filed application, Serial Number 727,013, filed February '7, 1947. However, said later application discloses and claims improvements relating to the locking of the rod and of the toggle links, not disclosed herein.

What I claim as new is:

1. A device of the class described comprising: a base-having a central opening formed therethrough; a rod having a peripheral bead formed adjacent one end, said end being insertable into said opening, and said bead being larger than said opening for clamping an objecta-gainst the edges of said opening; a threaded pres-sure exerting mechanism for, upon being threaded in one direction, exerting pressure on said rod longitudinally thereof for pressing said bead towards said base; and means for swingably mounting said pressure mechanism on said base.

2. A device of the class described comprising: a base formed cup-shaped on its under side to provide an inverted cup-shaped portion, the inner surface of the bottom of this cup-shaped porticn being upwardly inclined from the outer edges thereoflsaid bottom having a central opening formed therethrough and the outer surface of said bottom being upwardly inclined from the outer edges thereof towards said opening; a pair of arms each projecting outwardly from opposite sides of said base in diame-trical alignment with each other diametrically of said opening; a pair of legs hingedly connected at their lower ends to said arms; a cross-head carried on the upper end of i said legs and having a threaded opening formed therethrough; a screw threaded through said threaded opening; a rigid connecting member extending outwardly from said base at an angle to said arms; a toggle link; means for connecting one end of said toggle link ot the outer end of said rigid connection; means for connecting the opposite end of said toggl link to said cross-head, said toggle link being of such length that when extended said screw will be maintained in longitudinal alignment with the opening in said base; a presser rod; a circumferential bead on said rod adjacent the lower end thereof, said lower end being adapted for being embraced by the foreskin of a person to be circumcised, and said lower end of said rod being projectable through said opening, said bead being larger than said opening for clamping the foreskin against the edges of said opening, said screw being so located relatively to said rod as to exert pressure upon the same into clam-ping relation upon the threading of said screw in one direction.

3. A device of the class described comprising: a base having a central opening formed therethrough; a cross-head; supporting means rigidly connected at their upper ends to said cross head and swingably connected at their lower ends to said base for maintaining, upon swinging of said supporting means into upright position, said cross-head in elevated spaced relation to said base; a toggle mechanism for maintaining said supporting means in upright position; a rod; a peripheral projection on said rod inwardly from one end, said end being projectable through said opening and said end being adapted for being embraced by the foreskin of a person itO be circumcised, said peripheral projection being larger than said opening; and pressure exerting means carried by said cross-head for engaging said rod and forcing the same downwardly for clamping the foreskin between said projection and the edges of said opening.

4. A device of the class described, comprising: a base having a central opening formed therethrough; a rod having a peripheral bead formed adjacent one end, said end being insertible into said opening, and said bead being larger than said opening for clamping an object against the edges of said opening; a threaded pressure exerting mechanism for, upon being threaded in one direction, exerting pressure on said rod longitudinally thereof for pressing said ibead towards said base; means for swingably mounting said pressure mechanism on said base, the pressure exerting mechanism being swingable to operative and inoperative position relatively to said base; and means connected to said base and said pressure operating mechanism for maintaining said pressure operating mechanism in fixed relation to said base when swung to operative position.
