13 Claims.

My invention relates to an instrument adapted to facilitate the making of closures or jointures, especially in operations upon lthe intestine, and the process of using the same.

The object of my invention is to provide an apparatus and process of using the same, whereby jointures or closures generally may be readily made and whereby especially operations upon the intestine may be carried out more expeditiously and with greater certainty and uniformity in results. A further object is to more effectively prevent the escape of any contents, as, for instance, intestinal contents and at the same time prevent bleeding during the operation. Further objects of my invention will appearrfrom the detailed description of the same hereinafter'.`

While my invention is capable of being carried out in many different ways, for the purpose of illustration I have shown only one embodiment of the apparatus involved therein, in the accompanying drawings, in which- Fig. 1 is a side elevation of an apparatus;

Fig. 2 is a perspective view of the same;

Fig. 3 is a plan view of a portion of the gripping jaws, enlarged;

Fig. 4 is a perspective View of one set of gripping teeth;

Fig. 5 is a longitudinal section of a protector used on the end of the pin;

Fig. 6 is a diagrammatic section showing the way used for closing the end of the intestine;

Fig. 7 is a diagrammatic elevation showing the initial step of clamping two ends of intestines together where two ends are to be joined;

Fig. 8 is a similar View showing the way of Sewing the two ends together;

Fig. 9 is a diagrammatic View showing the end of an intestine about to be joined to the side of an intestine;

Fig. l0 is an elevation showing the step of clamping the end to the yside of the intestine; and

Fig. 11 shows them as finally joined together.

In the accompanying drawings, I have shown an operating instrument comprising a clamp-like apparatus which comprises two jaws 1 and 2, pivoted together by means of a pivot pin 3 and having handles 4 and 5, respectively, one of Said handles 4, having a screw-threaded arm 6 secured in a slot 7 so as to be inserted and withdrawn from a slot 8 in the handle 5. A thumb-screw 9 on the arm 6 enables the clamping jaws to be tightly held together. The jaw 1 is provided withl a sinuous jaw surface 10 to intert with a similar surface 11 on the jaw 2, of such a shape that when the intestine is inserted betweenthe .jaws there will be formed a channel 12 of approximately the width of the intestine clamped together throughout the length of the channel 12. In this way it will be noted that rounded teeth'13 and 14 60 are formed on the jaws 1 and 2, respectively, and that in said teeth 13 and 14 there are provided notches 15 which, inthe clamping position of the instrument with the intestine l'clamped in place, that is to say, when the channel 12 is approxi- 65 mately of equal width throughout, there will be just sufficient room in the notches 15, between the teeth 13 and 14, tofprovide v,room for receiving a pin 16 having a knurled handle 17, on the end of whiehthere is adapted to be placed a guard 18 to prevent theoperator from being injured or becoming infected from the point of the pin 16; 'I'he guard 18 is comprised of a pear-shaped housing 19 having a tapered forward end 20 with an opening 21 to receive the end of the pin and a 75 rearward opening 22 to receive a tubular plunger 23 which has longitudinal slits 24 at the forward end to provide clamping fingers 25 which become wedged around the pin near the opening 21 due to the tapered end of the housing 19. The plunger, furthermore, has a shoulder 26 to receive a coil spring 27 which normally forces the plunger 23 towards the opening 21. The rear of the plunger has a knob 28 permitting the same to be withdrawn to release the pin and a closure 29 to pre- 35 vent the point of the pin from projecting through the end of the plunger 23. It will be noted that the clamping jaws 1 and 2 are outwardly curved so as yto permit the guard 18 to be placed over the end of the pin 16. v

In carrying out my invention, it will be understood that theapparatus described may be used in joiningportions of the'intestine or other tissues,`in many dii'erentw'ays. However, for example, it may be used particularly for closing the end of an intestine or joining two ends thereof together, or joining an end to .a side of the intestine.

In the case where the end of the intestine is to be closed, the end of the intestine is inserted between the clamping jaws 1 and 2 and the jaws clamped together with the thumb-screw 9, after which the pin 16 is then inserted vand the guard 18 is placed over the end of the same. The clamping device is then removed and the end of the intestine is then sewed together by cross-stitches 30 of catgut, so that the free ends of the intestine are then directed inwardly, as shown in Fig. 6. After the stitching is completed the pin 16 can be removed. If desired, an additional sewing 110 the latter.

Where two ends 31 and 32 of the intestine arel to be attached together, these are first clamped between the clamping jaws 1 and 2 as shown in Fig. 7, the pin 16 is then inserted and the guard 18 applied thereto, whereupon the excess ends of the intestine are cut off, the clamp is removed and the intestine stitched all around the outside of the intestine, as shown in Fig. 8. Thereafter the pin 16 is removed. Y

In the case where an end 33 of, the intestine is to be attached to the side of an intestine 34, the procedure is similar tothat where the two ends of the intestine are to be joined together, in that the side 34 of the intestine is clampedbetween the. jaws 1 and 2 together1 `with the end 33 of the intestine. At this time a slice can be taken from the clamped fold of the sideof the intestine. The Yclamp is then removed and the stitching with catgut is applied all around the ladjacent surfaces of the intestine 33 and the intestine 34, so that the joined end to side appear as in Fig. 11 'after thepin 16 has been removed.

While I have described my invention above in A, detail I wish it to be understood that many changes may be made without departing from the spirit of the same., 1
