Claims

[Scope of utility model registration request]

comprising a switching valve provided in the operating section of the endoscope and connected to the suction means and the water supply means, and one channel that opens at the distal end of the insertion section and whose proximal end is connected to the switching valve, In the pipe switching device for an endoscope that allows selective suction or water supply from the distal end of the insertion section through the single channel, the switching valve is provided with an operation button that can be rotated and pushed. , an endoscope characterized in that when the operating button is pushed in at the first rotational position, water is fed through the channel, and when the operating button is pushed in at the second rotational position, suction is performed. Mirror pipe switching device.
