Abstract
During the treatment of biological tissues by high-frequency surgery, contaminants, in particular smoke, are produced. In the present invention a suction device for removal of the contaminants is controlled in such a way that it becomes active only when a voltage sufficient to ignite an arc exists at an applicator of the HF-surgery device, and/or an arc is burning between the applicator and the treatment region, and/or the treatment region reaches a temperature at which smoke can be produced.
