Abstract

The invention relates to medical instruments. A device for plasma surgical treatment of biological tissues comprises an anode unit (1), a cathode unit (2), a switching holder (11) and a rod-shaped electrode (12) secured in the holder (11), as well as a chamber (17) for plasma generation between the end of the electrode (12) and the internal end face of an outlet channel (8). The device according to the invention is provided with a cylindrical bushing (3) coaxially mounted in the casing (4) of the anode unit (1) and secured between the anode and cathode units (1, 2) by means of inserts (20, 21) of an electroinsulating material. The cavity (15) of the bushing (3) is connected to the cavity of the cylindrical holder (11). The distance lK from the end of the electrode (12) to the internal end face of the outlet channel (8) is linked with diameter dK of the channel (16) of the bushing at this section by the following relationship: 2 « lK/dK « 6. The invention may be used in general surgery, urology, oncology.
