ELECTROSURGICAL SYSTEM FOR REDUCING/REMOVING ESCHAR ACCUMULATIONS ON ELECTROSURGICAL INSTRUMENTS

摘要

An electrosurgical system is disclosed that applies electrical energy to obtain a predetermined surgical effect, while also reducing eschar deposits on a working surface of an electrosurgical instrument (4), producing an eschar deposit which is easily removed from the working surface, and/or facilitating removal of eschar deposits during a cleaning procedure. Such benefits may be realized by providing a negative bias on the working surface relative to a return path (7) to source (1) during electrosurgical procedures, and/or during a cleaning procedure which may include contacting the working surface with an electrically conductive liquid.
