The electrosurgical instrument comprises a working part (1) provided with two annular electrodes (3, 4) which are separated from each other with a disk (2) made of an insulating material, a drive (an electric motor (5), which is connected with the rotation axis of the working part (1) through an output shaft (6) and a reduction gear (7)) for rotating the working part (1) and current collectors (10), each of them interacting with the appropriate annular electrode (3, 4). The cutting working part (1) is provided additionally with a blade (14), the cutting edge (15) of which is fabricated as a circle arc not exceeding 90<o> of an arc defined along an outer circumference of the working part (1). The cutting edge (15) may project beyond the limits of the outer circumference of the disk (2), or coincide therewith. The electrosurgical instrument is intended primarily for surgical operations on soft tissues: muscles, fasciae. |
