1. An electrosurgical device comprising:
a housing;
electrode tubing in said housing;
a port at a proximal end of said electrode tubing for connecting a channel in said electrode tubing to a source of pressurized inert gas;
a port at a distal end of said housing for discharging inert gas flowing through said channel;
an electrode extending through said housing;
a fiberglass plate in said housing;
an electrical connector connected to said electrode and said fiberglass plate, wherein said electrical connector is configured to connect to an electrosurgical generator;
controls in said housing for controlling application of electrical energy to said electrode and controlling a flow of gas into said channel from said source of pressurized inert gas, said controls comprising two buttons extending through a side of said housing; and
a sliding control member extending out of a slot in a side of said housing wherein said sliding control member is movable between a first position in which a distal end of said electrode is within a distal end of said housing and a second position in which said distal end of said electrode extends out of said distal end of said housing.
