<P>PROBLEM TO BE SOLVED: To enable a guide wire to be fixed at the end of the endoscope insertion tube with simple operation, and to fully ensure the fixing strength. <P>SOLUTION: An operating tool raising base 27 is provided with a guide wire fixing groove 72 that fixes only the guide wire 20 on a side 71 of an operating tool guiding surface 29. Further, the operating tool raising base 27 is provided with a wire fixing hole 73 to fix a means of pulling the operating tool raising base 27, and with a rotating shaft hole 74 at a position where it serves as the axis for the rotation. The height and the position of the guide wire fixing groove 72 are determined so that the thin guide wire may be pinched and fixed between the guide wire fixing groove 72 and the storage chamber side wall at the distal end of the endoscope when the operating tool raising base 27 is raised. <P>COPYRIGHT: (C)2004,JPO |
