RU53135U1 - COMPRESSION DEVICE FOR FORMING AN INTESTINAL ANASTOMOSIS - Google Patents

Abstract

A compression device for the formation of an intestinal anastomosis, containing shapes made of a material with a “memory” effect, jaws connected together, one of which is curved at the end, reduces the time of rejection by increasing the pressure on the fixed tissue. This effect is achieved due to the fact that in the cross section the branches are teardrop-shaped and with pointed surfaces facing each other.

Description

A useful model - a compression device for the formation of an intestinal anastomosis - relates to medical equipment and can be used to form an intestinal anastomoses during surgical treatment of patients with diseases of the colon.

A compression device is known that contains molds made of a material having the “memory” effect and interconnected jaws, one of which has a bend at the end (Kecherukov A.I., Ziganshin R.V., Aliev F.Sh. Surgical treatment of hemorrhoids in the clinic // Surgery. - 1994. - No. 11. - P.26-29.).

However, this device used in the treatment of hemorrhoidal disease contains jaws having a rounded shape in cross section. During operation of the device, this reduces the pressure on the fixed tissue, prolongs the time of its rejection, and thereby limits the possibility of using this device in the formation of intestinal anastomoses.

The objective of the utility model is to develop a device for the formation of an intestinal anastomosis, which reduces the time of its rejection by increasing pressure on the fixed tissue.

This problem is solved by the fact that in the compression device for the formation of an intestinal anastomosis, containing shapes made of a material having the effect of "memory" and interconnected jaws, one of which is curved at the end, in the cross section the jaws are drop-shaped and the pointed surfaces face each other to a friend.

A utility model - a compression device for forming an intestinal anastomosis - is illustrated by the description and illustrative material, which shows:

Figure 1 - compression device for the formation of interintestinal anastomosis, General view;

Figure 2 is a cross section of the jaw of a compression device for forming an intestinal anastomosis.

A compression device for forming an inter-intestinal anastomosis (Fig. 1) contains interconnected branches 1 and 2 made of a material having the effect of a “shape memory", for example, nickel-titanium grade TN-10. In this case, branches 1 and 2 have a drop-shaped cross section and face with pointed surfaces 3 and 4 towards each other. At the same time, the end of the jaw 2 has a bend 5 in the direction of the jaw 1.

A compression device for forming an inter-intestinal anastomosis is used as follows.

During the operation, well-known techniques provide access to anastomosed portions of the intestine. Using a surgical clamp, jaws 1 and 2 of a pre-chilled device are bred at 15-30 ° and placed on a section of the intestine dissected to the mucous membrane. After that, the end of the jaw 1 start for bending 5 at the end of the jaw 2.

In the postoperative period, due to the “memory” effect, the shape of the material from which the device is made, branches 1 and 2 are compressed, thereby ensuring the intersection of the fixed part of the intestine. Due to the fact that the surfaces of branches 3 and 4 facing towards each other are made pointed, the intersection of intestinal tissues occurs faster, which leads to accelerated rejection of the device, which is naturally derived.

The use of the proposed device for the formation of inter-intestinal anastomosis showed that it provides a reduction in the time of its rejection by increasing pressure on the fixed tissue.
