Abstract

An accessory extends appts. for carrying out directed, tissue-protective, liq.-supported h.f. coagulation in endoscopes uses in medical operations. A pump aggregate with a reservoir is controllable in pressure and flow throughput. The reservoir can contain e.g. distilled, sterilised water. The pump aggregate is integrated into a h.f. surgical appts. so that the liq. can be conveyed to the coagulation electrode. The liq. leaves continuously from bores in the electrical contact surface. The tip of the coagulation electrode is slidable in an axial direction against the force of a suitably-adjusted spring in order to limit the contact pressure automatically.
