By the way, since the conventional conduit for raising the forceps is designed so that both the conduit on the distal end side and the operating part side communicate with the outside air, when it is inserted into the body cavity for inspection. Since a pressure difference is generated between the pressure inside the body and the pressure outside the body, the filth inside the body cavity enters deep inside the duct to cause contamination of the endoscope. For this reason, the pipe is capped during the inspection, and the cap is removed only when the pipe is washed to send the washing liquid.
However, since the cap is frequently removed and attached, the cap may be removed or the endoscope may be inspected with the cap left unattached, so that the filth is often inserted deep inside the tube.

Therefore, as shown in FIGS. 6 and 7, the outlet 52 of the conduit 51 on the operating portion side of the endoscope is provided in the air / water feeding cylinder 53 or the suction cylinder 54, and the air / water feeding button is used. 55 so that the outlet 52 is sealed when the 55 or suction button 56 is provided.
