<P>PROBLEM TO BE SOLVED: To provide an endoscope suction pipeline changeover device capable of efficiently performing suction operation without being affected by slide resistance and dispensing with processing of high precision. <P>SOLUTION: The endoscope suction pipeline changeover device 30 includes a pipeline member 31 and a suction switch 69a being a cap-shaped operation part. The pipeline member 31 has the first pipeline part 33 communicating with the suction channel 69d arranged on the side of an insertion part 10 and the second pipeline part 35 communicating with the suction device 73 connected to an endoscope 1. The suction switch 69a is movable to the pipeline member 31 with respect to the axial direction of the pipeline member 31 and performs suction changeover operation by movement. The suction switch 69a is movable to either one of a first position where the second pipeline part 35 is allowed to communicate with the outside of the endoscope 1 and a second position where the communication of the second pipeline part 35 with the outside is cut off and the first pipeline part 33 is allowed to communicate with the second pipeline part 35. <P>COPYRIGHT: (C)2012,JPO&INPIT |
