Abstract
Concepts presented herein relate to an interface module that can be electrically coupled to an electrical stimulation generator, a radio frequency generator and an instrument. A selection module is coupled to the interface module and operates in a first mode to deliver electrical stimulation signals from the electrical stimulation generator to the instrument and in a second mode to deliver radio frequency signals from the radio frequency generator to the instrument.
Claims8
A surgical system for use on tissue at a target site, the surgical system comprising:
- an instrument;
- an electrical stimulation generator configured to generate electrical stimulation signals;
- an electrosurgical unit configured to generate radio frequency signals;
- an interface module electrically coupled to the instrument, the electrical stimulation generator and the electrosurgical unit, the interface module configured to receive an indication of a bio-electric response caused by stimulation of the tissue from the electrical stimulation signals;
- a first circuit including the instrument, the electrical stimulation generator and the interface module;
- a second circuit including the instrument, the electrosurgical unit and the interface module;
- and
- a selection module electrically coupled to the interface module and utilizing an electronic switch configured to continuously complete the first circuit and selectively complete the second circuit;
- wherein upon receiving the indication, the interface module automatically disables the second circuit to prevent radio frequency signals from being sent to the instrument.
