Abstract
An electrosurgical instrument for providing pressurized ionized gas to a surgical site includes a hand-held applicator having proximal and distal ends, a gas delivery member adapted to deliver pressurized ionizable gas to the proximity of an electrode located adjacent the distal end of the hand-held applicator. A portable actuator assembly is included that is capable of receiving a source of pressurized ionizable gas therein. The actuator controls the delivery of the gas and energy to the hand-held applicator. A pressure safety connects to the portable actuator and to the hand-held applicator. A pressure safety system having two or more cascaded pressure change members connects between the input port and the output port, the pressure change members are configured to regulate pressurized gas into the environment until the portable actuator assembly exceeds a predetermined threshold.
