<P>PROBLEM TO BE SOLVED: To provide a beak shape treatment instrument for an endoscope which is provided with excellent durability, with which a spindle for supporting a beak shape treatment piece so as to be freely opening/closing is hardly separated from a support body when an external force is added to the spindle from any direction in the support body provided at the distal end of a sheath. <P>SOLUTION: The two spindles 5 for independently supporting the pair of beak shape treatment pieces 4 so as to be freely openable/closable in a slit 3 formed in the support body 2 provided at the distal end of the sheath 1 are put through holes 10a, 10b from mutually different directions, which are formed parallel in the support body 2 so as to cross the slit 3. The head parts 5a of the respective spindles 5 are formed to be too large to pass through the holes 10a, 10b, so that the distal end parts of the spindles 5 are respectively fixed to the support body 2 at each position for crossing the slit 3. <P>COPYRIGHT: (C)2004,JPO |
