US 12,685,579 B2 · Thermal management of an electrosurgical generator

Abstract

An electrosurgical generator for operating an electrosurgical instrument is characterized by a control device which is adapted to control a cooling device at least with a first control curve and a second control curve, wherein the first control curve is used to control the rotational speed of the cooling device depending on the monitored temperature during a first operating mode of the electrosurgical generator and the second curve is used to control the rotational speed of the cooling device depending on the monitored temperature during a second operating mode of the electrosurgical instrument, wherein the first control curve and the second control curve are different from each other. A method for operating an electrosurgical generator for operating an electrosurgical instrument and to an electrosurgical generator system includes an electrosurgical generator and an electrosurgical instrument.
