(57) Abstract:

Usage: medicine for the imposition of esophago-intestinal anastomosis. The inventive elastic ring presses the intestine wall and the wall of the esophagus to the narrowed part of the sleeve, after which the rod sever and remove part of the device through the mouth and the auxiliary hole. 2 C.p. f-crystals, 9 Il.

The invention relates to medical equipment and can be used to overlay the esophago-intestinal anastomosis.

The closest to the invention is apparatus for blending esophago-intestinal anastomosis, containing made thicker rod mounted on the rod sleeve with the outer surface in the form of truncated cones, which are oriented towards each other with smaller bases, mounted on a rod movable auxiliary tube telescopically related inner and outer cups, placed on the inner glass movable elastic ring, a handle, a tubular housing connected to the outer Cup and connected with the bottom of the inner glass rod placed with the opportunity to interact with the handle of the latch.

A disadvantage of the known apparatus is slegna tissue folds may be of different thickness, and the axis of the bushings located on the flexible traction, immersion may shift, resulting in the postoperative period will be impaired patency of the anastomosis. In addition, the flexible traction on the esophagus into the mouth associated with the trauma and inconvenience of the manipulation.

The proposed device solves the problem of increasing the reliability of the anastomosis when the relief operation.

In Fig.1 - shows a General view of the apparatus; Fig.2-7 - stages overlay anastomosis; Fig.8 is a section along a-a in Fig.1; Fig.9 - section b-B in Fig.1.

The proposed device contains made thicker 1 rod 2 mounted on the rod sleeve 3 with the outer surface in the form of truncated cones, which are oriented towards each other with smaller bases installed on the mobile terminal 2 auxiliary tube 4, telescopically related inner and outer 5 to 6 cups placed on the inner glass 6 movable elastic ring 7, arm 8 and the tubular body 9. The rod 10 is connected with the outer Cup 5 and the bottom of the inner Cup 6. The latch 11 is placed with the opportunity to interact with the handle 8. The apparatus additionally introduced rigidly coupled to the housing 9, the stop 12, and the rod 1 with the inner glass figure 6 surface with flats 13 and a rectangular hole 14. The latch 11 is made in the form housed in the handle 8 spring-loaded valve that is installed with the ability to communicate with the terminal 2 and the stop 12. The cones of the outer surface of the sleeve 3 is oriented toward its center. Terminal 2 is movable with a shortened 15 working part. Thickening 1 rod 2 made in the form of the end surface at the inner surface of the sleeve 3, and the rod 15 is provided with an additional thickening 16 with a spherical surface at the esophageal probe 17.

The device works as follows.

At the end rugged in total gastroektomii esophagus impose a purse string suture 18. The working end of the probe 17, wound through the mouth into the esophagus, through the slot 19 is connected with a spherical thickening 16. Plunging shortened part 15 of the rod together with put on him the auxiliary tube 4 in the lumen of the esophagus, tighten and fasten purse string suture 18 to the auxiliary tube 4. Then the auxiliary tube is removed from the shortened part 15 and make it to the end of the crossing of the small intestine with a pre-imposed purse string suture 20, which tighten and fasten the tube 4. In the intestine through the auxiliary hole is slid apparatus. The end of the elongated portion 21 steroi part. Holding the shortened part 15 of the rod of the surgical clip, connect the two parts of the rod. Elongated portion 21 of the rod being located in the extended part 22 of the fork, made in the valve 11, holds the latter in cooperation with the projecting part of the stop 12, which in turn keeps the body 9 with an outer Cup 5 in a stationary position. In this case, valve 11 compresses the spring 23. Gently pull the rod out of the machine and formed on the shorter part of the flats 13 is installed in the rectangular hole 14 made in the bottom of the inner Cup 6. When the circular groove 24 of the rod reaches the level of the narrowed part of the plug valve 11, the spring 23 pushes the valve, Sasakawa groove 24 in the tapered part of the plug. This is achieved by fixing the rod in the position in which the cone sleeve 3 is located in the middle part on the level of the inner end of the Cup 6. Simultaneously, the protruding portion of the stop 12 is released from the relationship with the valve 11, is released from the slot 25 of the handle 8, allowing free longitudinal movement of the housing 9 is connected to it the outer Cup 5 relative to the tube 10 and the inner Cup 6 bearing elastic ring 7. This PE is with elastic ring 7 with the inner Cup 6 accurately narrowed in place of the sleeve 3. Elastic ring 7 from the lumen of the intestine pushes the intestine wall and the wall of the esophagus to the tapered portion of the sleeve 3. The rotating rod for thickening 27, divide both parts of the rod. The device is removed from the intestine, and sew the auxiliary hole. A shortened portion of the rod is removed along with the probe 17 through the mouth.

Thus, the proposed device provides a reliable anastomosis and its patency after the operation. The device is simple and convenient in operation.

SUBSTANCE: method involves creating central end-to-end anastomosis of blood vessel and synthetic prosthesis. Porous titanium nickelide device of 50-65% porosity and pore size of 50-200 mcm, is conducted through peripheral vascular prosthesis end. The cylindrical device is not shorter as 25 mm and has longitudinal slit. The device is set in a way that the slit and anastomosis line are overlapped with the cylinder at distance not shorter than by 5 mm and aorta segment adjacent to the prosthesis at 25 mm long distance. The longitudinal slit is arranged on blood vessel wall with slightest deviation and fixed on both sides with 2-3 sutures.

SUBSTANCE: one should suture both adducting and abducting intestinal parts with separate sutures without any primary fixation of esophagus to an abducting intestine. Then one should apply esophagointestinal anastomosis. Moreover, by applying external suture of anastomosis' anterior wall one should suture serous-muscular layer of adducting intestine, esophageal muscular layer and serous-muscular layer of abducting intestine. After covering internal anterior row of sutures and nearing the walls of abducting and adducting intestinal loops one should apply 2-3 serous-muscular sutures on them at the top. On should finish the development of a cuff due to both adducting and abducting part of small intestine. The suggested method enables to decrease intraluminal pressure in duodenum, decrease the risk of duodenal stump's failure, and obtain antireflux-type mechanism of anastomosis.

EFFECT: more simplified and shortened terms for applying the anastomosis.

SUBSTANCE: one should isolate cavitary neoplasm of abdominal cavity, apply anastomosis between adducting and abducting loops, cut a strip of 5-7 mm width and length up to 100 mm out of vascular prosthesis to apply it through mesentery of adducting loop being 20-30 mm against interintestinal anastomosis, suture free ends of this strip at intestinal serosa to form a ring. Ring's diameter should be determined by the following formula: where D2 - desired diameter, D1 - diameter of small intestine, d - thickness of small-intestinal wall. The ring should be peritonized with sutures. The innovation enables to exclude pressing of intestinal tissues and eliminate anatomical intestinal permeability in area of the closure suggested above.

SUBSTANCE: the present innovation could be applied for treating patients with the tumor of pancreatic caput. One should cross right-hand gastro-omental vessels at the level of duodenal crossing, dissect gastric body along the greater curvature by locating incision line being parallel to the lesser curvature and at not less than 5 cm against pylorus being proximally regarding the stomach. Then one should suture anterior and posterior gastric walls, suture in pancreatic section into posterior wall of the greater curvature being proximally against incision line antiperistaltically. The method enables to isolate pancreatic stump against gastric content at keeping its pyloric department in case of pancreatoduodenal resection.

EFFECT: higher efficiency.
