<P>PROBLEM TO BE SOLVED: To provide a medical mechanism for controlling forward/backward movement which can control the forward/backward movement of an endoscope tool within a tool channel to regulate easily the projection, and facilitates the determination of an early position; and a medical method for controlling forward/backward movement. <P>SOLUTION: The medical mechanism for controlling forward/backward movement 50 includes a controller 60 mounted detachably to an insertion hole 40, and an abutment 80 mounted to a bendable tube 210. The end surfaces 65a, 66a of the controller 60 makes the abutment 80 abut against the end surfaces 65a, 66a when the endoscope tool 200 (the bendable tube 210) moves forward/backward within the tool channel 39, thereby regulating the forward/backward shift of the endoscope tool 200. The abutment 80 abuts against the end surface 65a to regulate the projection of a curve 211 projecting from the tool channel 39, while the abutment 80 abuts against the end surface 66a to regulate the backward movement of a tip 212, and determines the early position of the tip 212 within the tool channel 39. <P>COPYRIGHT: (C)2010,JPO&INPIT |
