<P>PROBLEM TO BE SOLVED: To provide an endoscopic treatment tool capable of storing by coiling an insertion member and operating a treatment part under conditions where the insertion member is small coiled. <P>SOLUTION: An endoscopic treatment tool 1 has an insertion member 3 of which the short sheath 20 and the long sheath 21 are connected serially, and the long sheath 21 is formed by loosely jointing a plurality of joint pieces 22 with ligature wire. A storing device 4 includes a sheath coiling member 42 for coiling the long sheath 21 and a wire coiling member 43 for coiling an operating wire, which drives a treatment part 2, separately from the long sheath 21. The wire coiling member 43 can rotate under conditions of the fixed sheath coiling member 42, and the operating wire can be moved forward and backward toward the long sheath 21 when the wire coiling member 43 is rotated under conditions where the long sheath 21 and the operating wire are coiled. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
