Abstract
An electrosurgical instrument comprises a cutting portion which incorporates two active electrodes made as similar disk cutters (2, 3) arranged coaxially and at a clearance with respect to each other, a power actuator to impart rotation to the cutters (2, 3), and current leads to supply a diathermic current to the electrodes. The cutting edges of the disk cutters (2, 3) are essentially regularly alternating toothed portions (4, 5) and toothless portions, the toothed portions (4) of the cutter (2) being arranged staggerwise with respect to the toothless portions of the cutter (3).
