The invention discloses an intracavity
endoscope cleaning and
smoke discharging device which comprises an outer sleeve, a locking fixing base, a self-debugging sealing cap, a first cover body, a second cover body, an inner core
pipe, a first
choke valve and a second
choke valve. The camera is replaced, placed in the device, penetrates through the inner core
pipe and ejects the second
choke valve at the bottom of the inner core
pipe, at the moment, the second
choke valve is opened, in the observation process, if the camera is polluted, the camera is pulled into the inner core pipe, at the moment, the second
choke valve is closed, the camera is located in the second
choke valve, and a water inlet and suction switch is turned on; water flows into the inner core tube from the inside of the outer sleeve, then the water outlet and inlet suction switch is turned on, the water flows are sucked out through large
suction force, meanwhile, pollutants are brought out of the inner core tube, the purpose of cleaning the camera is achieved, operation is easy, the learning cost is extremely low, and the working efficiency of doctors is improved.
