Description

SURGICAL INSTRUMENT.

The useful model refers to the field of medicine, namely to surgical instruments designed to separate soft tissues used in normal, pathological and topographic anatomy, forensic medicine, etc.

When performing a number of operations on the organs of the abdominal and chest cavity, for example, during appendectomy, it is necessary to cut the skin into a strictly defined depth and width (5-7 mm) for passing through this hole, for example, a laparoscopic trocar, tubular drains, etc. .

For the separation of tissues, special surgical instruments are used, for example, scalpels, which differ both in overall dimensions and in the form of the cutting element (1).

Known surgical instrument containing a rod with a handle and a cutting element (2).

The disadvantage of this surgical instrument is the increased complexity and complexity of the tissue incision of a strictly defined depth and diameter.

A known surgical instrument containing a cutter, a blade with a cutting edge and a pick (3).

The disadvantage of this surgical instrument is the difficulty of using it to conduct tissue incision of a strictly specified depth and length.

A surgical instrument is also known, containing a shaft with a handle at one end and a cutting element at the other (4).

The disadvantage of this surgical instrument is the increased complexity of performing a tissue incision of a strictly specified depth and length, which is necessary, for example, when performing an appendectomy to install a laparoscopic instrument.

. Cl. A 61 at 17/32

The purpose of creating a utility model is to reduce the complexity of performing a soft tissue incision of a strictly specified depth and length.

This goal is achieved by the fact that a limiter of depth and length of penetration of the cutting element into the fabric equipped with a position lock and made in the form of a sleeve with a hole congruent with the cross section of the rod is mounted on the rod with the possibility of longitudinal movement and fixing in a predetermined position, wherein the position lock made in the form of a sleeve, equipped with a support flange.

Comparison of the claimed technical solution with other well-known solutions in this field of medicine showed its compliance with the criteria of a utility model.

The utility model is illustrated by graphic material. In FIG. 1 shows a General view of the proposed surgical instrument; in FIG. 2 is a section AA in FIG. 1.

The surgical instrument comprises a shaft 1 with a handle 2 at one end and a cutting element 3 at the other end. On the rod 1 is mounted with the possibility of longitudinal movement and fixing in a predetermined position, a limiter for the depth of penetration of the cutting element into the fabric, made in the form of a sleeve 4 with a hole 5 congruent to the cross section of the rod 1. The sleeve 4 is equipped with a position lock 6 on the rod 1, made, for example, in the form of a screw, and a supporting flange 7.

The surgical instrument is used as follows.

To install trocars for laparoscopic operations, for example, appendectomy, it is necessary to make an incision of the anterior abdominal wall deep and 5-7 mm long. The surgeon determines the required depth and length of the incision. Sets the limiter 4 in the required position and fixes this position with a screw 6, pierces the skin on

the required depth and length, introduces trocars, then they perform surgical intervention in the usual manner.

The use of the proposed surgical instrument during surgery, for example, appendectomy, made it possible to instantly cut the required diameter and depth for the introduction of trocars of a certain diameter, which in turn made it possible to improve the quality of the operation by reducing the time of the operation, improving the cosmetic effect and shortening the treatment time .
