SURGICAL GENERATOR FOR ULTRASONIC DEVICES AND FOR ELECTROSURGICAL DEVICES

SURGICAL GENERATOR FOR ULTRASONIC DEVICES AND FOR ELECTROSURGICAL DEVICES

A surgical generator (102) that may produce a drive signal or signals of particular voltages, currents and frequencies, e.g. 55,500 cycles per second (Hz). The drive signal or signals may be provided to an ultrasonic surgical device (104) and specifically to a transducer. In one embodiment, the gene...

Zusammenfassung:A surgical generator (102) that may produce a drive signal or signals of particular voltages, currents and frequencies, e.g. 55,500 cycles per second (Hz). The drive signal or signals may be provided to an ultrasonic surgical device (104) and specifically to a transducer. In one embodiment, the generator may be configured to produce a drive signal of a particular voltage, current and/or frequency that can be stepped with high resolution, accuracy and repeatability. Additionally, the surgical generator may generate a drive signal or signals with output power sufficient to perform bipolar electrosurgery using radio frequency (RF) energy. The drive signal may be provided, for example, to electrodes of the electrosurgical device (106). Accordingly, the generator may be configured for therapeutic purposes by applying electrical signals to an ultrasonic transducer or electrical energy to the tissue sufficient for treating the tissue (e.g., cutting, coagulation, cauterization, tissue welding).
