Abstract

PURPOSE:To prevent the relative rotation of an elastic plate and a flexible tube even when the elastic plate is bent in a direction reverse to a bending habit within the channel of an endoscope, by providing an elastic plate rotation preventing means to a part of the flexible tube. CONSTITUTION:An elastic plate 4 imparting a bending habit is inserted in a flexible tube 1 and an electric incising conductive wire 5 is also inserted therein in a freely advancing and retracting state. This conductive wire 5 is exposed to the outside of the flexible tube 1 between through-holes 2, 3. A rotation preventing part 16 for preventing the rotation of the elastic plate 4 by deforming the flexible tube 1 is formed to the flexible tube 1 within the range opposed to the incision part 5 on said flexible tube 1.
