Abstract
A method for operating an electrosurgical system including an ultrasound generator and an ultrasonic instrument, includes the steps: determining an initial resonant frequency of the ultrasonic instrument by the ultrasound generator, energizing the ultrasonic instrument by the ultrasound generator with an operating amplitude and an operating frequency which correspond to the initial resonant frequency, tracking the operating frequency of the ultrasound generator with changes in the resonant frequency of the ultrasonic instrument, and terminating the energizing of the ultrasonic instrument by the ultrasound generator. A method terminates the energizing of the ultrasonic instrument by the ultrasound generator, in a decay phase the operating amplitude of the ultrasound generator is reduced to zero with a predefined or predefinable rate of change. An ultrasound generator is also presented.
