Abstract

The invention is intended for surgery. The purpose of the invention is to reduce the trauma when a purse-string suture is applied to the intestine or esophagus in hard to reach places. The tool contains branches 1 and 2 with working jaws 3 and 4 having transverse corrugations on the inner surfaces. The working jaws are fixed on the branches with the help of hinges 5 and 6 with the possibility of turning them in a plane perpendicular to the branch plane on the BWO. Two pins 7 are fixedly fixed on the sponge 4, and sponges 8 are respectively fixed on the sponge 3, respectively. The longitudinal groove on the working jaws 3 and 4, which holds the thread through the corrugated fabric to lead the needle, has a diamond-shaped cross-section. 3 il.

The invention relates to medical technology, namely, instruments for applying a purse string to the organs of the digestive tract. :

The purpose of the invention is to reduce the trauma when a purse-string suture is applied to the intestine or esophagus in hard-to-reach areas of the small pelvis or under the diaphragm, as well as to simplify the technology of manufacturing the longitudinal groove.

Figure 1 presents the tool, a general view; in FIG. 2, the location of the pins and sockets on the working jaws} in FIG. 3 is view A in FIG. 2.

The instrument for putting the purse string suture contains the branches 1 and 2 with working jaws 3 and 4, which have transverse corrugations on the inner surfaces. The working jaws are fixed on the branches with the help of hinges 5 and 6 with the possibility of turning them in a plane perpendicular to the branch plane by 360. Two pins 7 are fixed on the sponge 4, and sockets 8 are made on the sponge 3, respectively, the pins m. A longitudinal groove on the working jaws 3 and 4, which serves to draw a needle with a thread through a corrugated fabric, has a diamond shape in cross section.

The tool works in the following way. . ,

Working tool sponge impose on the area of the intestine or esophagus, where it is necessary to impose a purse string. Working sponges szhimayt so that the pins of one sponge fell into the nest of another that. eliminates the displacement of one sponge relative to another when they are jointly rotated and contributes to a firm retention of the clamped tissue.

With this overlapping work sponge, the colon or esophagus is folded in half and crimped. Then a needle with a thread is inserted into the longitudinal groove of the most conveniently located end of one of the working jaws. However, it is often impossible to remove the needle from the opposite end of the indicated sponge during operations in the small pelvis or under the diaphragm, and in order to remove the needle and thread the needle through the second working sponge, it is necessary to turn the compressed sponge with a clamped cloth at an angle, sometimes up to 180, and after that it is easy and convenient to remove the needle and insert it into the longitudinal groove of the butt of the second jaw, i.e. complete the pouch suture.

The use of the instrument allows a purse-string suture to be applied to the intestine or esophagus in hard-to-reach areas of the pelvis or under the diaphragm.
