UA66294A - Device for bipolar electrocoagulation of blood vessels of low and middle diameter - Google Patents

Abstract

The device for the bipolar electrocoagulation of the blood vessels of low and middle diameter represents the two-branch forceps. The operating parts of the branches are 3.8-4.0 mm in the width. The branches are coated with the insulating material throughout their length except for the planes 2 mm in diameter located internally in the operating ends of each branch intended for conducting the diathermic current used for electrocoagulation.

Description

The invention relates to medicine, namely to medical technology, and can be used in all sections of surgery, where hemostasis of vessels is performed during surgical interventions.

The closest to the claimed technical solution is tweezers consisting of two branches, the working ends of which have a width of 1.5-2 mm, and have an insulating coating only in the middle and near the junction of the branches.

The working ends of the branches are devoid of insulating material (1, 2).

The disadvantage is the limited possibilities of this coagulation of vessels with a diameter of up to 2 mm, the passage of current from the side of the branches, which leads to overheating of the surrounding tissues. The use of an instrument with a small contact area and the sharp edges of the branches lead to the crossing of the vessel wall. This is also facilitated by the boiling of blood between the branches during the passage of current.

The invention is based on the task of developing a device for performing bipolar electrocoagulation of vessels of small and medium diameter, in which, due to the presence of insulating material on the branches and the conduction of diathermic current through the areas of the working ends of the branches that are not covered with insulating material, it is possible to avoid damage to the surrounding tissues during electrocoagulation.

The task is solved by the fact that, according to the invention, the working ends of the branches have a width of 3.8-4.00 mm, and the branches themselves are covered with insulating material on all surfaces, except for the planes with a diameter of 2 mm, located on the inner surfaces of the working ends of each branch, through which it passes diathermic current during electrocoagulation.

Figure 1 shows a device for performing bipolar electrocoagulation of vessels of small and medium diameter, where: 1 - tweezers; 2 - branches covered with insulating material;

C - planes on the inner surfaces of the branches, free of insulating material.

The device is tweezers 1, which consists of two branches 2 covered with insulating material, the working ends of which have a width of 3.8-4.0 mm, and on the inner surface of each branch there is a plane 3 with a diameter of 2 mm, free of insulating material.

The device works as follows. During coagulation, with the help of tweezers, the vessel is grasped and compressed with moderate force along the length, i.e., proximal to the bleeding site. At the same time, a diathermic current is applied to the branch 2 of the tweezers, which passes through the planes 3 and the walls of the vessel located between the branches of the tweezers. This leads to coagulation of the vessel walls and the formation of a coagulation scab, which ensures reliable hemostasis.

In comparison with the prototype, the proposed device allows achieving stable and reliable hemostasis, as well as avoiding damage to surrounding tissues during electrocoagulation. Wide branches ensure displacement of blood from the vessel over a sufficient length of it, which eliminates the possibility of blood boiling during coagulation, and this, in turn, leads to the formation of a stable, well-fixed coagulation scab.
