VORRICHTUNG ZUM DIATHERMISCHEN ABTRAGEN VON WUCHERUNGEN

The present apparatus is a so called polypectome for the diathermic removal of growths, such as polyps, especially from the intestinal tract, by means of a high frequency heated wire loop which is extended out of and pulled back into a flexible tubular member. A guide bushing for the wire loop is located at the outer end of the tubular member. The guide bushing comprises guide means therein which guides the loop so that it forms an oval in its extended position and substantially an eight in its retracted position. The wire loop has a bent tip having a diameter which is smaller than the inner diameter of the guide bushing to facilitate the controlled shaping of the loop.
