- 摘要：
PROBLEM TO BE SOLVED: To provide a treatment instrument for an endoscope exerting an excellent treatment function by forming a distal treatment member into a length beyond the conventional common-sense length and being smoothly inserted/extracted with respect to the interior of a treatment instrument insertion channel of the endoscope.
SOLUTION: The distal treatment member 2 is formed of a plurality of divided pieces 2A to 2C serially continued in the longitudinal direction, connecting wire rods 3 formed by longitudinally staggering bendable sections 3C and non-bendable sections 3B are inserted into through-holes 4 longitudinally straightly formed in the whole bodies of the plurality of divided pieces 2A to 2C, and the connecting wire rods 3 are axially advanced/retracted from the proximal end side of a flexible sheath 1, so as to change over the distal treatment member 2 between a bendable state and a rigid state at the connecting portions between the plurality of divided pieces 2A to 2C.
