ABSTRACT:
A sliding tube is disposed within a cylindrical insertion pipe. Around the insertion pipe there is provided a surrounding wall member defining a space with the pipe, said space communicating with a suction instrument via a suction pipe and simultaneously with the interior hole of the insertion pipe via a communicating port. The opening planes of the respective upper end opening portions of the insertion pipe and space are rendered substantially flush with each other, each of said upper end opening portions having a size large enough to permit it to be closed by the operator's finger. When an injection instrument is fitted into the upper end opening of the insertion pipe, the sliding tube is lowered to close said communicating port. The surrounding wall member is detachably fitted to a receiving member secured to an endoscope body.
