FIELD: medical engineering. ^ SUBSTANCE: device has hollow cylinder having conic sharp end at the working end and a handle on the opposite end. Cylinder surface has three zones of which two are conducting in the areas adjacent to the ends and the third one between them is insulated. A part of cylinder surface and the whole sharp end surface belong to conducting zone of a working end. Conducting zone of an end opposite to the working one serves for supplying electric current. The insulated zone has restricting member on the side opposite to the working end current amplitude; avoided burns and foreign chemical substances production in tissues under treatment. ^ EFFECT: enhanced operation reliability. ^ 6 cl, 3 dwg |
