<P>PROBLEM TO BE SOLVED: To provide a high frequency treatment device for an endoscope which is capable of performing the smooth and accurate incision treatment of a mucous membrane by arbitrarily changing the stiffness strength of the part of a distal tube provided with an exposed electrode responding to the hardness or the like of a mucous membrane being an incision target. <P>SOLUTION: The high frequency treatment device for an endoscope is constituted so that the exposed electrode 4 is exposed to the outside of the distal tube 3 between a pair of the electrode through holes 5 formed to the distal tube 3 and the distal tube 3 is rotated in the direction centering around an axial line with respect to a proximal side tube 1 by rotating a conductive wire in the direction centering around the axial line with respect to the proximal side tube 1 from the proximal end side of the proximal side tube 1, and provided with a movable reinforcing tube 8 for enhancing the stiffness strength of the distal tube 3 by the part which is inserted into and drawn out of the distal tube 3 from the inside of the proximal side tube 1 by the operation from the proximal end side of the proximal side tube 1 to be passed through the distal tube 3. <P>COPYRIGHT: (C)2010,JPO&INPIT |
