US 2022/0022934 A1 · ELECTROSURGICAL GENERATOR AND ELECTROSURGICAL SYSTEM WITH VARIABLE FREQUENCY OUTPUT

Abstract

The present invention provides an electrosurgical generator and an electrosurgical system with variable frequency output. The electrosurgical system with variable frequency output comprises: high frequency electrosurgical instruments and an ultrasonic surgical instrument and the electrosurgical generator, wherein the high frequency electrosurgical instruments and the ultrasonic surgical instrument share one energy output interface or respectively use different energy output interfaces. An energy switching system is further arranged in the electrosurgical generator, can switch an output energy type at any time according to needs, so as to avoid frequent changes of the surgical instruments.
