ABSTRACT:
A bipolar medical coagulation and/or cauterizing instrument has two elongated electrodes with first end portions which constitute the working end of the instrument and second end portions which are connectable to different poles of a high-frequency generator. The intermediate portions of the electrodes are surrounded by deformable insulators which are shrunk onto the respective electrodes and are confined in a tubular member serving to prevent the electrodes from moving relative to each other. To this end, the intermediate portions have cross sections which are out-of-round and/or which vary in the longitudinal direction of the respective electrodes. The insulators closely follow the outlines of the respective intermediate portions, and the tubular member closely follows the outlines of the insulators.
