Abstract

An endoscope, particularly for coagulating or resectioning parts of the cartilage of the meniscus of the knee joint under application of a unipolar HF loop electrode that has a supply lead which extends, together with an optical system, through an endoscope tube for proximal connection to an HF generator. The endoscope tube is electrically insulated externally and is provided at its distal end with excisions at either side of its vertical axial plane to form apertures and a stem delimiting the electrode loop at the distal end is situated in the vertical axial plane in the area of the excisions within the tube.
