Abstract

The present invention is directed to an endoscopic implant cutting and/or fragmenting apparatus of the bipolar type, operating on direct current, comprising an endoscope instrument having at least two opposing electrodes at its distal instrument head forming a cutting gap inbetween for receiving an electrically conductive implant or implant section to generate punctiform physical contact with the implant, and a DC-impulse generator connected to a control device adapted to generate a direct current in a pulsed way such that in a first phase of physical contact, the current pulse is adjusted to induce electric energy into the implant material being sufficient to melt the implant material exclusively in the area of the contact portion and in a second phase of physical noncontact, the current pulse is adjusted to generate an electric arc between at least one electrode and the melted implant material being sufficient to cut the melted implant material.
