Gas-Enhanced Surgical Instrument

An actuator assembly for providing pressurized gas to an electrosurgical instrument, the assembly comprising:

• a source of pressurized gas;
• a housing configured to receive the source of pressurized gas;
• an actuator pivotably secured to the housing;
• and
• at least one controller located within the housing and configured to be coupled to a source of pressurized gas, the at least one controller controlling the delivery of the gas from the supply of pressurized gas to the electrosurgical instrument, wherein the actuator is configured to engage the at least one controller upon actuation and the source of pressurized gas is visibly coded to indicate a characteristic of at least one of the type of gas in the supply of pressurized gas and the pressure of the pressurized gas.
