New models of forceps for bipolar coagulation

: Operations on the brain require an optimum coagulation effect to be produced by forceps for bipolar coagulation. New forceps models are described in which the elimination of heat from the operating ends is considerably improved by making the whole forceps of copper and providing intermittent supply of high-frequency current to it. As a result the coagulation effect is distinguished by slight necrosis of the tissues adjoining the ends of the forceps and no sticking of these tissues to these ends.
