Abstract
A drive unit for a rotatable high-frequency electrode of a medical resector for cutting, ablating, or coagulating human or animal tissue includes an engine device for generating a rotation movement and a coupling device for transmitting the rotation movement generated by the engine device to an axis coupled with the rotatable high-frequency electrode when the drive unit is coupled with the medical resector. The drive unit is configured to provide on the coupling device a rotation frequency in a range from 10 rpm to 200 rpm.
