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.
Claims10
A drive unit for a rotatable high-frequency electrode of a medical resector for cutting, ablating, or coagulating human or animal tissue, having:
- an engine device for generating a rotation movement;
- a coupling device for transmitting the rotation movement generated by the engine device to an axle coupled with a rotatable high-frequency electrode when the drive unit is coupled with a medical resector;
- and
- a locking device for locking the coupling device of the medical resector in the drive unit, wherein the locking device includes a spring-loaded bolt that is configured to engage in a groove in an axle of the medical resector,
- wherein the drive unit is configured to provide on the coupling device a rotation frequency in a range from 10 revolutions per minute to 200 rpm.
