Instrument for the endoscopically controlled shortening and / or fragmentation of stents located in the gastrointestinal tract, bronchotracheal system,

摘要

It is an instrument for the endoscopically controlled shortening and / or fragmentation of stents located in the gastrointestinal tract, bronchotracheal system, made of electrically conductive material. This comprises an electrode device, with an electrode for the introduction of a hf - current to flow into a wire of the stent as well as a protective device that is designed and is mechanically connected with the electrode device, that the wire during the introduction of the hf - current of tissue is separable.
