Abstract
The invention concerns an endoscopic instrument for the high frequency surgical treatment of tissue in body cavities by using a liquid produced as a result of a wash penetrating the cavity. The instrument has a shaft which can be introduced into the cavity and by means of which an active electrode can be placed in the liquid volume. The instrument further has a neutral electrode and a high-frequency generator to which both electrodes are connected by insulated leads. The invention is characterized in that the neutral electrode is arranged at a distance from the active electrode in the liquid volume.
