Inert gas-enhanced electrosurgical system

Definition

An assembly of devices that uses radio-frequency (RF) alternating current to develop heat directly within soft-tissue cells (thermodynamic) for cutting and coagulating tissue within a shield of an inert gas [e.g., argon (Ar), helium (He)] during surgery. It typically includes a generator, a single-use/reusable electrode handpiece with monopolar electrodes, connecting cables, foot-switch, and a gas supply system [housed in a separate trolley (cart) or incorporated into the system generator]. The current forms an ionized channel or arc within the gas shield which lessens the charring of tissue and provides rapid, uniform coagulation over large bleeding surfaces (e.g., capillary beds).
