Abstract

Usage: in experimental medicine, upon receipt of standard sutured wounds of the hollow organs of the digestive tract. SUMMARY OF THE INVENTION: A tissue fixing clip is inserted through a slot in an organ wall, a shop is applied around the clip without being pulled in, the tissue is cut around the clip, the thread is pulled in as the fabric is removed along with the clip, which improves accuracy by dissection and suturing fixed fabric. 1 ill.

Description

with

The invention relates to experimental surgery, and in particular, to methods for applying standard sutured wounds to hollow organs, for example, the stomach.

The purpose of the invention is to increase accuracy by dissecting and suturing fixed tissue.

This goal is achieved by the fact that before applying the incision, one of the sponges of the surgical clamp is inserted through the cut into the organ cavity, the sponges are brought together and fixed with a cremalley mechanism, a suture thread is carried out under the sponge into the organ cavity along the length of the sponges, and the incision is made on both sides jaws and as the thread is tightened, the clamp is removed from its cavity along with the excised part of the organ.

By introducing one of the clamping jaws into the organ slot, then bringing the jaws together and fixing them, reliable fixing of the organ tissue before cutting is achieved. The uniform pressure of the sponges on the fabric allows for precise cutting.

By passing the suture thread under the jaw lips through the tissues on both sides of the jaws, which are the edges of the wound after cutting the organ and correspondingly making cuts on both sides of the jaw lips, it is possible to exclude the mucous membrane turning out, to precisely match the edges of the suture when suturing, which helps to eliminate errors experiment associated with inaccurate adaptation of the edges of the wound, and consequently, increased accuracy.

Due to the gradual tightening of individual or continuous sutures (previously applied to the organ tissue) along

as the clamp is removed, it is also possible to achieve the accuracy of standard wounds.

An example (Fig. 1). After opening the Oryus cavity in the acral part of the stomach, closer to the greater curvature, a through cut wound 1 5 mm long was applied. Through this wound, one of the sponges 2 or 3 of a long surgical clamp with flat elastic lips was held against the stop. After this jaw of the clamp, 2 m 3 were connected by engaging its handle. The clamp is clamped together. a portion of the wall was lifted and at a distance of 8 mm from each other (there are marks on the jaws of the clamp) by piercing the wall through all the layers, a continuous catgut thread 4 was passed, passing under the clamped jaws. The formed loops of the 5 catgug five shifted anteriorly. Then, using a puff probe, the inside of the stitch and the catgut yarn was lowered down about 1 cm into the organ sifted. This was done in order to protect the suture material from being damaged by the cutting tool. The tissue captured in the clamp was dissected with a blade 6 along the edge of the clamp, first on one side and then on the other side. After that, immediately ixa simultaneously pulled both ends of the catgut yarn until the edge was completely matched as the clamp jaws were removed from the organ cavity and tied into a knot. Nylon threads 8 were passed through a serous-muscular layer over a perpendicular row of sutures 7 at a distance of 5 mm to 6 mm from each other.

The proposed method does not exclude the use instead of continuous

catgut suture nodal. It is also possible suturing separately and on the mucous membrane. Only in this case, the serous membrane is dissected first.

along the edge of the outer jaw of the clamp, which then easily moves away from the jaw by about 5-7 mm. After that, a catgut thread is also preliminarily drawn, only through the mucous membrane, and after

exceptions and juxtaposition of edges impose nodular serous-muscular sutures. The experimental studies using this method on 96 rabbits revealed the following advantages:

allows to get standard sutured wounds in all animals; J Accurate and sutured wounds on hollow organs are achieved;

the method makes it possible to accurately match the opposite edges of the wound;

Claims (1)

the accuracy of experimental studies is improved. The claims A method of obtaining standard sutured experimental wounds of the hollow organs of the digestive tract, including carrying out an incision of a certain length and suturing with a continuous suture, characterized in that, in order to increase the accuracy by dissecting and suturing the fixed tissue, the clamp is fixed with jaws, one of which introduced into the lumen of the organ, the incision is performed according to the walls of the jaws after preliminary ligature is applied around them, and the thread is tightened as the fabric is removed along with the clamp. m-sh
