Abstract

The invention relates to medical technology, namely to surgical suturing apparatus for applying anastomoses. The purpose of the invention is to increase the constancy of the anastomosis by uniformly distributing compressive forces over the surface of the connecting rings. The surgical stapler contains a connecting ring 5 and a connecting ring 6 with an annular cavity. Compressing the intestinal walls, the connecting ring 6 due to its softness and elasticity, obtained from the annular cavity, contacts all the irregularities of the intestinal walls and ensures a uniform distribution of the compressive forces over the entire surface, compensating for possible unevenness of the connected tissues. 1 hp ff. 2 Il.

FIG.

The invention relates to a medical elevation, in particular to surgical stitching apparatus for the application of anastomoses.

The purpose of the invention is to increase the constancy of the anastomosis by uniformly distributing the squeezing forces over the surface of the connecting rings.

FIG. 1 shows schematically the working part of the apparatus, a section; in fig. 2 - the same, after the formation of the anastomosis.

The surgical stapler comprises a housing 1, a stop head 2, a movable rim 3 with locking needles 4, an intermediate ring 5 and a connecting ring 6 with an inner annular cavity 7 and holes 8 for passing the locking needles 4, a knife 9.

.The surgical fusion apparatus works as follows.

To form an anastomosis in the distal parts of the rectum after the affected part of the intestine has been removed, pouch sutures are put on both stumps. After that, the device with the installed connecting rings 5 and 6 is inserted into the intestinal lumen through the anal canal. When the stop head of apparatus 2 is shown from the stump of the rectum, the device is diluted and the purse string is sutured between the diluted rings 5 and 6. Next, the head of apparatus 2 is inserted into the lumen of the colon and the second string suture is tightened on the stem of the apparatus head 2 with a ring 5. Parts of the device with suction sections of the intestine bring together and produce tissue stitching with simultaneous circular cut of tissues with a knife 9. Movable crown 3 with locking needles 4 finally fix the connecting rings 5 and 6, 1 rpchem needle easily pass through the coaxial through holes 8 and also pierce the ring 5 easily. The cylindrical knife 9 cuts off along with the purse-string suture and excess # /

Kami intestinal walls and waste of the cut ring 5, which are removed together with the head of the apparatus 2. Rings 5 and 6 compress the tissue of the intestinal walls. The rubber connecting ring 6 has, due to the cavity 7, a greater degree of deformation. Compressing the intestinal walls due to its softness and elasticity, it comes into contact with all the irregularities of the intestinal steioc and ensures an even distribution of the pressure across the entire surface, compensating for possible unevenness of the connective tissues. The apparatus is removed, and the squeezing elements remain.

Thus, the 4 soft elastic connecting ring 6, which interacts with the locking needles, fills all the irregularities of the stitched intestinal walls, cushions and creates uniform distribution of pressure and soft tissue contact along the entire perimeter in the zone of healing, which makes it possible to bias the compression ring 5 safely.

Claims (2)

1. A surgical stapler comprising a tubular body, a stop head, a movable rim with locking needles and connecting rings of elastic material, the first of which is mounted on the stop head, and the second with openings for passing the locking needles on the casing, distinguished by that, in order to increase the consistency of the anastomosis by uniformly distributing compressive forces over the surface of the connecting rings, the second connecting ring is made with an internal annular cavity and Leno such a way that its end-face end of the housing for the stands. 2. The apparatus according to claim 1, wherein the second ring is made of rubber.
