ABSTRACT:
A suction operating apparatus in an endoscope consisting of an outer cylinder connected to a sucking channel of the endoscope, an inner cylinder removably fitted to this outer cylinder and having a sucking hole on the side, a valve body made of an elastic material and having a slit in a closing part provided in the lower end part of this inner cylinder and closing a lower end opening of the inner cylinder, an operating member provided so as to be free to advance and retreat within the inner cylinder, and to be pushed into the slit of the valve body to open and close this slit, thus forming a fluid flow path communicating with the sucking hole in the axial direction, and an elastic cover for elastically returning the operating member to the fixed position from the pushed-in position.
