<P>PROBLEM TO BE SOLVED: To provide a projecting/retracting treatment implement for an endoscope facilitating an appropriate and precise endoscopic treatment so as to be desired by an operator by arbitrarily adjusting and retaining the projecting length of a distal end treatment piece from the distal end of a flexible sheath and arbitrarily adjusting and retaining its rotating direction around the axis. <P>SOLUTION: At least a part adjacent to the distal end of the flexible sheath 1 is formed of a flexible tube, and a wide width portion 3c, which is formed into a shape expanding from the distal end treatment piece 3 to the radial direction of the flexible tube and radially expanding the flexible tube, is formed adjacent to the proximal part of the distal treatment piece 3. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
