Claims7
A surgical apparatus for facilitating testing nerves during high-frequency surgery, comprising:
- a high-frequency generator for generating a high-frequency treatment current,
- a converter for converting the high-frequency treatment current into a nerve stimulating current;
- connecting lines for feeding the high-frequency treatment current from the high-frequency generator to the converter;
- and
- a controllable selector switch for selectively feeding one of the high-frequency treatment current and the nerve stimulating current to a high-frequency electrosurgical instrument,
- wherein the converter comprises a rectifier circuit for generating a direct current as the nerve stimulating current.
