<P>PROBLEM TO BE SOLVED: To provide an endoscopic treatment tool whose protrusive length of a tip treatment segment from a flexible sheath is made in a simple and highly practicable structure at a low cost so as to be stably adjusted and maintained at a predetermined length while used over a long time. <P>SOLUTION: An elastic friction drag applying member 4 is pressed into a region around the tip of the flexible sheath 1 with crushed and elastically deformed by an internal surface of the flexible sheath 1 and the outer surface of an operation wire 2 so that the friction drag caused acts respectively between the operation wire 2, the friction drag applying member 4, and the flexible sheath 1 in response to a movement of the operation wire 2. <P>COPYRIGHT: (C)2008,JPO&INPIT |
