る。As described above, the mucus collecting apparatus for an endoscope according to the present invention has a mucus-absorbing property at the distal end of an operation wire inserted in a flexible sheath inserted into a body cavity so as to be able to advance and retreat. A liquid is provided so that the mucus-absorbing liquid-absorbing liquid can be protruded and retracted as needed through the opening of the distal end of the flexible sheath by advancing and retracting the operation wire, thereby preventing contamination when collecting mucus. I can do things. Further, there is a special effect that the outer diameter of the flexible sheath is small and the flexibility of the flexible sheath can be easily improved.
