<P>PROBLEM TO BE SOLVED: To provide an endoscope simplifying a structure compared with electrically driving a treatment instrument, suppressing the buckling of the treatment instrument in the middle of inserting/drawing it into/from the channel compared with a case of manually inserting/drawing, facilitating the replacement of the treatment instrument, and shortening and facilitating the manual operation. <P>SOLUTION: This endoscope is provided with a flexible insertion tube 2 to be inserted in the body cavity, an operating section 3 connected to the proximal end of the insertion tube 2, a channel 5 communicating the insides of the insertion tube 2 and the operating part 3, an inserting/drawing mechanism driving the treatment instrument 6 inserted in the channel 5 at a predetermined inserting/drawing driving force, a manual operation part 8 connected to the inserting/drawing mechanism 7 and manually supplying the inserting/drawing driving force to the inserting/drawing mechanism 7, and a storage part 10 having its inside communicated with the channel 5, connected to the proximal end, and storing the treatment instrument 6. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
