ELECTROSURGICAL SYSTEM, ELECTROSURGICAL GENERATOR, AND METHOD OF OPERATING AN ELECTROSURGICAL SYSTEM

An electrosurgical system, including: an electrosurgical generator, and an electrosurgical instrument configured to connect to the electrosurgical generator through a three-pin connector; wherein the electrosurgical instrument includes an electrosurgical electrode connected to a first pin of the three-pin connector, and one of an activation switch circuit and an instrument identification circuit connected to a second pin and a third pin of the three-pin connector; wherein the electrosurgical generator is configured to detect, upon connection of the electrosurgical instrument to the electrosurgical generator, whether the electrosurgical instrument includes an activation switch circuit or an instrument identification circuit; and, if the electrosurgical instrument includes an activation switch circuit, connect the second and third pin of the three-pin connector to an activation switch unit, or, if the electrosurgical instrument includes an instrument identification circuit, connect the second and third pin of the three-pin connector to an instrument identification unit.
