Electric drive for tissue ablation device, has drive motor, where drive is completely integrated in closed housing, and electrical energy required for drive motor is inductively transferred via housing by transformer

摘要

The drive has a drive motor, where the drive is completely integrated in a closed housing. The electrical energy required for the drive motor is inductively transferred via the housing by a transformer. The movement that is produced by the drive motor is transferred to a cutting device by a magnetic coupling that is effective by a closed housing wall. The housing takes function of an ergonomic handle for a keyhole surgery instrument.
