Abstract

The invention relates to medical technology and can be used for high-quality endocardial electrosurgery in the treatment of patients with supraventricular arrhythmias. The aim of the invention is to reduce the morbidity of the operation by lowering the temperature in the area of the electrode. The contact element of the electrode is hollow, thin-walled, with openings in the wall on its working side for the flow of coolant, and on the non-working side is covered with a dielectric. -2 or less

Description

The invention relates to medical technology and can be used in medicine for high-quality endocardial electrosurgery in the treatment of patients with supraventricular arrhythmias.

The purpose of the invention is to reduce the trauma of the operation by lowering the temperature in the zone of action by the electrode.

Figure 1 shows the endocardial electrode: figure 2 - contact element, a section.

The electrode includes a housing 1 made of a thermoplastic insulating material, a conductor 2, inside which there is a channel 3 for introducing the stylet and supplying a coolant, a hollow thin-walled contact element 4. On the working side of which the perforation is made in the form of openings 5 for cooling fluid endocardium with high-frequency coagulation. The opposite side of the contact element is covered with dielectric.

The electrode is used as follows (for example, in the case of high-frequency electrical destruction of the atrial-ventricular junction in order to create an artificial AV blockade).

Electrode placed inside it. With the olive stylet, the puncture route (using the Seldinger technique) is inserted through the right femoral vein. After the stylet is removed from channel 3, the electrode is installed in the area of the atrioventricular junction. Then, through the channel 3 in the handle, the electrode is connected to the simtema for cooling and connected to a high-frequency apparatus. After it is turned on at the same time, through the channel 3 in the conductor 2, a cooling liquid is supplied, which flows out through the openings 5 from the working side of the contact element 4, cools

tissue during exposure to high frequency energy. At the same time, in the zone of action no tissue carbonation is formed and more deep-lying tissue sections coagulate more qualitatively. The liquid at the same time has room temperature. If the electrode is not immediately removed in the zone of the AV node, then through the channel 3 in the handle, the electrode is connected to the infusion system for cooling and connected to a high-frequency apparatus. After connecting the electrode, simultaneously through channel 3 in the conductor 2, in the zone of influence, coolant is supplied at a temperature of + 4 ° C, which, flowing through the holes 5 on the working side of the contact element, causes a short 0
