GENERATOR AND OPERATION METHOD THEREOF

Abstract: a generator that includes a drive circuit connected to a surgical instrument including a vibration system having a probe and an ultrasonic transducer, which supplies power to the ultrasonic transducer. the control circuit detects a first trigger causing the control circuit to perform a resonance-point search on the vibration system. upon detecting the first trigger, the control circuit determines a resonance point of a frequency of vibration of the probe by performing the resonance-point search, and upon determining the resonance point, causes the drive circuit to execute a standby operation. the control circuit then detects a second trigger causing the surgical instrument to treat the living tissue, and upon detecting the second trigger, causes the drive circuit to execute an actual output operation by increasing the supply of power to the surgical instrument such that the surgical instrument treats the living tissue.
