Gas-enhanced surgical instrument
First Claim
1. An electrosurgical instrument for providing pressurized ionized gas to a surgical site, comprising:
- 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 applicator, the electrode being adaptable to connect to a source of electrosurgical energy; and
a portable actuator assembly configured to selectively receive a source of pressurized ionizable gas therein and having at least one controller that controls the delivery of the gas from the supply of pressurized inert gas to the hand-held applicator and controls the delivery of electrosurgical energy to the hand-held applicator; and
wherein upon actuation of the at least one controller, gas from the source of pressurized inert gas is delivered to the proximity of the electrode through the gas delivery member and electrosurgical energy is delivered to the electrode, such that an ionized gas is emitted from the distal end of the hand-held applicator.

Abstract
A gas-enhanced electrosurgical instrument includes a hand-held applicator and a portable actuator assembly. The hand-held applicator has a gas delivery member adapted to deliver pressurized ionizable gas to the proximity of an electrode located adjacent a distal end of the applicator. The portable actuator assembly is capable of holding a source of pressurized ionizable gas, such as a cylinder or cartridge, and includes at least one controller to control the delivery of the gas from the source to the hand-held applicator and to control the delivery of electrosurgical energy to the hand-held applicator.
