Description

This invention relates to medicine and can be used to close cavities in the lung by diathermocoagulation.

The purpose of the invention is to reduce the healing time of the cavity and, in addition, to coagulate the draining bronchus and the wall of the non-falling cavity.

The drawing shows a device for diathermocoagulation of cavities.

The device consists of coaxially arranged electrically conductive elements 1 and 2 with a dielectric coating 3 and 4. The working part of the inner element 1 has a larger diameter with respect to the rest, which ensures a transition flush from the working part of element 1 to the dielectric coating 4.

At the opposite end of the inner

the element has a conical nest 5. A conic contact 6 is inserted into the nest 5 with a conductor from one of the bi-active outputs of the apparatus for high-frequency electrosurgery.

On the inner member 1 there is a limiter 7 indicating the distance between the working parts. On the inner element 1 there is a scale 8, according to which the degree of extension of the inner element 1 is established in each particular case, which is determined by the diameter of the cavity.

The outer member 2 is a needle with a standard sharpening angle. The inner diameter of the outer element is somewhat larger relative to the outer diameter of the inner element 1. The gap is necessary for aspiration of air from the cavity when the electrode is inserted (the cavity collapses) into the cavity and during diathermocoagulation to keep the cavity wall in the collapsed state. In the case of significant drainage of the cavity by the diverting bronchus, the inner member 1 rises to the upper position and the lumen of the outer member 2 increases significantly, which ensures the cavity to collapse at any degree of drainage.

The opposite end of the outer element 2 (relative to the working one) is closed by an elastic membrane 9. The inner element 1 is fixed by an elastic membrane 9 which fixes the inner electrode in a predetermined position and simultaneously seals the outer element 2 during air aspiration when the device is inserted into the cavity.

On the side, element 2 is connected to a pipe 10 which is connected to a source 11 of reduced pressure. A conductor is connected to the nozzle 10, connecting the outer electrode to another bi-active output of the apparatus.

The diathermocoagulation of the cavity walls is carried out as follows.

The limiter 7 is set so that when extending the inner element 1, the distance between the working parts of the inner and outer elements 1 and 2 corresponds to the diameter of the coagulable cavity. Due to this position of the electrodes, the entire thickness (entire volume) of the folds of the cavity wall is coagulated (Fig. 4). The end of the working part of the inner electrode is set at the level of the cut-off of the outer element 2 or rises to the membrane 9, depending on the degree of drainage of the cavity.

Under the electron-optical transducer (x-ray control), the location of the cavity is determined. The center of the cavity is aligned with the axis of the outer element 2. The skin of the chest is punctured. Includes aspirating at 0 soy. The outer element 1 advances in the tissues of the thorax and lung until the cavern collapses. The pump is temporarily turned off and the cavity is expanded. The inner member 1 extends to the limiting body 7. In so doing, the inner member 1 abuts against the wall of the cavity. The aspiration pump is turned on again, the cavity collapses and its wall fits tightly on the outer 2 and inner 1 elements. The device turns on for 20-40 seconds

0 and conducted Diathermocoaguli of the walls of the cavity.

In the event that the cavity is expanded (the device is not removed, only the pump is turned off), the procedure of volumetric diathermocoagulation is repeated. In this case, the direct internal element 1 together with the conical holder is removed, and in its place another internal element 1 is inserted, bent so that, when it is inserted into the cavity, the active part of the internal element 1 is in the area of the draining bronchus. In order for element 1 to retain its shape, it is made of stainless steel material. The diathermocoagulation is repeated.

The device allows to significantly reduce the time required to close the cavity with the scar, since the volumetric diathermocoagulation takes place during the treatment period and does not require additional time for

0 closing of the cavity after reaching the rehabilitation of the cavity from the tuberculosis pathogen. The total duration of treatment, including the closure of the cavity, is about 15 days.

A special case of application of the device consists in diathermocoagulins of the wall of a non-falling cavern. In this case, dia-thermocoagulation is carried out to enhance reparative changes in the wall of the cavity and accelerate the cleaning of the wall of the cavity from

pathogens. It is also possible to simulate directly

an increase in the frequency of cavern closure. The X-ray image shows that the bends of the internal catheters 20-45 ° are sure. For a cavern diameter of 4 cm in this

the active part of the electrode or, with some cases, will require only three catheters.
