<P>PROBLEM TO BE SOLVED: To provide a treatment instrument for an endoscope, capable of correctly aligning a treatment function member with a desired direction by a simple operation of moving forward and backward a forward/backward moving member in an axial direction, thereby executing endoscopic treatment smoothly and rapidly. <P>SOLUTION: The treatment instrument for an endoscope includes: a treatment function member 15 rotatably supported on the distal end of a sheath 11; a forward/backward moving member 53 having one end fixed to the treatment function member 15; and a rotation control means 65 for changing the rotation position of the treatment function member 15 by the movement of the forward/backward moving member 53. The rotation control means 65 has a first engaging portion 67 formed integrally with the sheath 11, and has in the sheath 11 a drive member 51, a sliding member 71 having a second engaging member 69 to be engaged with the first engaging portion 67 and a guiding surface 73 sliding on the sliding member 71. In the instrument, the rotating member 75 supported by regulating the rotation of the forward/backward moving member 53 and an urging member 77 are coaxially disposed in this order. <P>COPYRIGHT: (C)2013,JPO&INPIT |
