(54) DEVICE FOR DIATERMOKOAGULATION

one

The invention relates to medical technology and can be used for surgical purposes.

A device for diathermocoagulation comprising tubular is known. conductive housing with a handle and a plug on the medial end mounted for movement in a guide tube made of a dielectric

However, this device does not provide reliable diathermocoagulation welding of the walls of the drained cavity, since, when pumping air from the cavity, it is not possible to achieve complete collapse of its walls.

The purpose of the invention is to improve the reliability of welding of the walls of the pathological cavity, which has drainage, bronchi.

The goal is achieved by the fact that a device for diathermocoagulation, comprising a tubular conductive body with a handle and a plug at the medial end, mounted for movement in a directional tube made of a dielectric, has four spring-loaded lobes mounted at the working end of the tubular body, as well as a metal rod with an insulating coating, which is mounted for movement inside the tubular body and provided with a screw at the working end and a fork at the opposite end.

FIG. 1 shows a device for diathermocoagulation, a general view} in FIG. 2 - the same, in working condition.

The device for diathermocoary contains a tubular body 1 rigidly fixed in a handle 2 made of a dielectric material. The tubular body 1 is connected by means of a conductor with a plug 3 located in the handle 2. On the opposite side is tubular, the body 1 ends with four identical spring elements 4, forming in

20 closed state truncated cone. A guide tube 5, made of a rigid dielectric, is fixed on the tubular body. At the base, the guide tube 5 terminates;

25 by a ring 6, and its end is sharpened under a cone 7. There is a longitudinal groove 8 in the wall of the guide tube 5. The guide tube 5 can be moved in the tubular body 1 within the limits of the longitudinal groove 8 and pin 30

VOLUME 9. In the extreme position, the guide tube 5 is secured with a spring retainer 10. Through the inner channel of the tubular body 1 and the hole in the handle 2 passes a metal rod 11 with an insulating coating 12. On one side, the metal rod 11 ends with a fork 13, and on the opposite - a screw 14.

The device is used as follows.

First, the instrument is prepared for a transthoracic puncture of a tuberculosis cavern. For this, the metal rod 11 is displaced so that the tip 15 of the screw 14 is at the level of the edges of the spring lobes 4. After that, the guide tube 5 is pushed to the extreme position and fixed with the spring lock 10, and the helix 16 of the screw 14 is clamped with the lips of the petals 4 , and its tip 15 becomes a continuation of the cone of closed spring petals 4,

In this position, the tool is inserted under control into the lung until the tips 15 contact the front wall 1 of the cavity 18. After that, the guide tube 5 is displaced until it contacts the handle 2, and the petals 4 are diverted,

Rotation of the metal rod 11 ensures that the screw 14 passes the front wall 17 of the cavity 18. After that, the rod 11 is displaced forward to screw the screw 14 into the rear wall 19 of the cavity 18.

Through wires 20 and 21, the device is connected to the terminals of the apparatus 22 for high-frequency diathermocoagulation.

After this, the metal rod 11, which is pushed, presses the back wall 19 of the cavity 18 to the front wall 17. In this position, the pedal 23 turns on the apparatus 22 for high-frequency diathermocoagulation. At the same time the walls 17 and 19 of the cavity 18 are welded

Thereafter, wires 20 and 21 are disconnected from the device and a screw 14 is pulled out of the fabric by rotating the metal rod 11. Next, the screw 14 is inserted into the tubular body 1, and

by displacing the tube 5, the petals 4 are closed. Only after this the instrument is removed from the body.

The device for diathermocoagulation ensures reliable wall welding.

pathological cavity with draining bronchi.
