ABSTRACT:
A passage structure of an endoscope which facilitates the passage washing operation by enabling all the passages to be washed with a washing brush passed through from the operating portion. A passage unit is removably attached to the operating portion, and the passages are exposed to a return portion provided at the rear end portion of the operating portion. The passage unit is provided with an auxiliary tube for, for example, flushing the lens surface, and an injection hole member having an injection hole and a replaceable check valve is removably connected thereto, thereby enabling washing of the tubes from the operating portion of the endoscope. A tight spring is fitted over a soft tube which is disposed in a straight line in the operating portion, and a tape is wound around the soft tube placed along a hard tube such as a suction tube. An adapter having a washing water injection hole is provided on the receiving portion of the operating portion which is connected to the passage unit, thereby facilitating a liquid chemical or the like to be injected to a fine tube.
