  • Publication number: 20230320774
    Abstract: A method for monitoring a high resistance condition at an instrument terminal of an electrosurgical generator, which includes current and voltage measuring devices for determining a current and a voltage at the terminal to determine the high resistance condition, and includes a calculation device connected to the measuring devices which is configured to evaluate the determined current and voltage, including: determining a crest factor value from the current and/or voltage, wherein the crest factor value describes a ratio of a peak value to an effective value of the current and/or voltage; comparing the determined crest factor value with a comparison value by means of a comparison device, wherein the comparison value is stored in a data storage device; and signaling a high resistance condition with a signaling device when the determined crest factor reaches or exceeds the predetermined crest factor comparison value. Also, an electrosurgical generator and electrosurgical generator system.

  • Publication number: 20210275242
    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.

  • Publication number: 20210228259
    Abstract: An electrosurgical system having an ultrasound generator, configured to emit a high-frequency electrical signal, and an ultrasound instrument, including an ultrasound transducer configured to convert the signal into an ultrasound oscillation, wherein the generator is further configured to determine a resonance frequency of the transducer and adapt a frequency of the signal to the resonance frequency, and wherein the generator is further configured to detect a phase position between the current and the voltage of the signal and based on the detected phase position to determine whether the frequency of the signal corresponds to the resonance frequency. To enable the resonance frequency of the transducer to be determined correctly irrespective of component tolerances, the electrosurgical system is characterized in that the generator is configured to consider, during determination of the phase position, correction values, which are or can be stored in a memory of the generator and/or of the instrument.

  • Publication number: 20170360496
    Abstract: A plasma surgery apparatus includes an HF generator for generating an HF activation signal, a gas source for providing a plasma gas, and a plasma applicator having a channel which opens out at a distal end of the applicator and through which the plasma gas can flow. The apparatus also includes an HF electrode that is electrically connected to the HF generator. When the HF electrode is supplied with the HF activation signal, a plasma is provided originating from the distal end of the applicator. The apparatus also includes a control unit and a flow regulator for regulating a flow rate the plasma gas in the channel. The control unit receives or requests an operating variable of the HF generator and, according to a saved functional relationship, controls the flow regulator so that the flow rate of the plasma gas is correlated with a detected value of the operating variable.
