Endoscope having auxiliary hole

摘要

An endoscope which is capable of appropriately sucking air in the stomach in endoscopic retrograde cholangiopancreatography, and which is capable of feeding and sucking a liquid and air at a portion other than the end portion. The endoscope comprises: an end portion which is also used as a suction hole and which is provided with a forceps insertion; a bendable flexible portion; and an auxiliary hole disposed in an outer peripheral groove formed in the middle of the flexible portion separately from the forceps insertion hole. An auxiliary receiving portion at the operating portion is connected to the auxiliary portion through a supply pipe. It is possible to feed or suck water or air from the flexible portion by mounting a syringe or the like in the auxiliary receiving hole. Since the auxiliary hole is disposed in the outer peripheral groove, sucking or feeding is not obstructed by a wall or the like in the body under observation.
