A wire section ( 1 ) inserted into a patient includes a wire ( 4 ) connected with a snare ( 3 ) at the front end thereof, and an outer tube ( 8 ) which retractably passes the wire ( 4 ) and the snare ( 3 ) therein. A remote control section ( 2 ) not inserted into the patient's body includes a bar-like main body ( 9 ) with a hollow inside; an operating member ( 11 ) connected to the main body ( 9 ) so as to be slidable in L and R direction and sled to enter or exit the snare ( 3 ) into and from the outer tube ( 8 ); and a pinching mechanism ( 15 ) built in the main body ( 9 ) and connected to the operating member ( 11 ) for detachably pinching the pipe ( 6 ) connected to the rear end of the wire ( 4 ). The wire section ( 1 ) and the remote control section ( 2 ) are connected when the pipe ( 6 ) is pinched by the pinching mechanism ( 15 ), and the wire section ( 1 ) and the remote control section ( 2 ) are separated when the pipe ( 6 ) is released from the pinching mechanism ( 15 ). |
