Endoscopes
First Claim
1. An endoscope for coagulating or resectioning damaged 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, wherein said endoscope tube is electrically insulated to prevent injury to adjacent areas of the knee joint anatomy and is provided at its distal end with distal delimiting excisions at either side of its vertical axial plane to form apertures in the sides of the tube for enflanking the damaged cartilage, said excisions having a geometry corresponding nearly to the cartilage to be enflanked, and wherein a stem delimiting said electrode loop at the distal end is situated in said vertical axial plane in the protected area of and between said excisions at the distal end of said tube.

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.
