Abstract
A high-frequency surgical device having a high-frequency generator, which produces a high-frequency output signal for treating, in particular for cutting or coagulating, biological tissue, the high-frequency generator being designed in such a way that the output signal of the high-frequency generator has a predetermined fundamental frequency and a modulation apparatus being provided, which is used to modulate the output signal with a modulation frequency, the modulation frequency being smaller than the fundamental frequency. The high-frequency surgical device is characterized in that the modulation frequency is at least 100 kHz, and in that the output signal can be modulated in such a way that a crest factor of the modulated output signal suitable for a specific application of the high-frequency surgical device arises.
