1. An electrosurgical instrument having a plurality of operating modes, comprising:
- (a) a console unit having;
i) a monopolar output connector supplying monopolar electrosurgical currents when the unit is energized,ii) a bipolar output connector supplying bipolar electrosurgical currents when the unit is energized,(b) a handpiece connected to both the unit'"'"'s monopolar output connector and the unit'"'"'s bipolar output connector,(c) first means for selectively energizing the unit to activate the monopolar output connector or the bipolar output connector to supply monopolar or bipolar electrosurgical currents, respectively, to the handpiece,(d) an electrode mounted in the handpiece, the electrode having a first position configured to perform an electrosurgical cutting action when supplied with monopolar electrosurgical currents and a second position configured to perform a coagulation action when supplied with bipolar electrosurgical currents.

Abstract
An electrosurgical instrument with which a single handpiece can be connected that can be used for cutting and for coagulation without touching the instrument after the front panel settings have been made. The handpiece, of the extendable electrode type, comprises essentially two cables one terminating in a male connector configured to mate to the bipolar output connector of the electrosurgical unit, and a second terminating in a male connector configured to mate with the monopolar output connector of the electrosurgical unit. The output connectors can be selectively activated.

16. A method of operating electrosurgical apparatus comprising:
-
A. providing an electrosurgical instrument having a plurality of operating modes, comprising; (a) a console unit having; i) a monopolar output connector supplying monopolar RF electrosurgical currents when the unit is energized, ii) a bipolar output connector supplying bipolar RF electrosurgical currents when the unit is energized, (b) a single handpiece connected to both the unit'"'"'s monopolar output connector and the unit'"'"'s bipolar output connector, (c) first means for selectively energizing the unit to activate the monopolar output connector or the bipolar output connector to supply monopolar or bipolar electrosurgical currents, respectively, to the handpiece, comprising the steps; B. operating the first means to supply monopolar electrosurgical currents to the handpiece to perform a cutting action on tissue, C. then operating the first means to supply bipolar electrosurgical currents to the handpiece to perform with the same handpiece coagulation of tissue bleeders. - View Dependent Claims (17, 18)
