Electrodes, Electrosurgical, Active
Definition : Electrosurgical electrodes designed to deliver radiofrequency (RF) electric current to the body tissues at the points where the current effect is required. Electrosurgical electrodes may be intended to apply monopolar or bipolar current. These electrodes deliver the RF energy through insulated cables from an RF generator located in the electrosurgical unit, they are usually a component of a handpiece (for monopolar units) or the distal tips of instruments (e.g., forceps, scissors) that are manipulated by the surgeon for bipolar surgery. The current circulation is controlled using hand or foot controllers (switches); some active electrode handpieces include mechanisms for smoke evacuation. Active electrosurgical unit electrodes are mostly used in procedures intended to cut tissues, stop bleeding, and/or for tissue fusion.
