<P>PROBLEM TO BE SOLVED: To appropriately adjust the direction of a treatment instrument with a simple operation without causing a rotational leap of a treatment section. <P>SOLUTION: This treatment instrument 1 for an endoscope includes a treatment section for treatment, an operation wire 3 connected to the treatment section, a coil sheath 9 into which the operation wire 3 is inserted, an insulating tube 10 into which the coil sheath 9 is inserted, and an operation section 4 for operating the treatment section. The operation section 4 includes a slider 15 rotatably connected with the operation wire 3, a body 13 to which the slider 15 is mounted movably forward and backward, and a rotational operation section 14 which is so mounted as to be rotatable with respect to the body 13 and has the coil sheath 9 so mounted thereto as to be not rotatable. The distal end of the insulating tube 10 is mounted rotatably and movably forward and backward to the distal end of the coil sheath 9. The side of the proximal end 10A of the insulating tube 10 is separated in a manner so that the proximal end side is relatively movable in an axial direction with respect to the coil sheath 9 and covered with the operation section 4 so as not to be exposed even when the coil sheath 9 curves. <P>COPYRIGHT: (C)2010,JPO&INPIT |
