The working principle is as follows: when in use, medical staff can tightly hold the laparoscope introduction auxiliary pipe 1 with one hand and stir the third flow regulating valve 13 through fingers, clean water can be supplemented into the water storage electric heating box 16, the water storage electric heating box 16 can heat the inflowing clean water, the heating temperature is consistent with the body temperature of a patient, the endoscope 15 is heated by the clean water, mist generation on the surface of the endoscope 15 is effectively avoided, the heating is uniform, the heat preservation effect can be achieved, the endoscope 15 is prevented from being deformed due to more concentrated heating surface, the water pressure in the water storage electric heating box 16 is increased, the first one-way valve pipe 18 is opened, on one hand, the surface of the endoscope 15 can be washed, pollutants such as tissue fluid, dirty blood and the like adhered on the surface of the endoscope 15 are removed, on the other hand, the washing requirement can be provided for abdominal cavity surgery, the second flow regulating valve 11 is stirred through finger belly, and gaseous carbon dioxide can be introduced into the water storage electric heating box 16, gaseous carbon dioxide can be wetted after entering the water storage electric heating box 16, and can be heated, so that water shortage of focus tissues can be avoided after the gaseous carbon dioxide enters the abdominal cavity of a patient, adverse reaction of the focus tissues can be avoided due to temperature difference, after the air pressure in the water storage electric heating box 16 is increased, the gas separation membrane has selective permeability, the clean water can be prevented from leaking out through the second one-way valve tube 19, the gaseous carbon dioxide in the water storage electric heating box 16 is not blocked from entering the abdominal cavity of the patient, the air pressure required by the abdominal cavity of the patient can be ensured, the first flow regulating valve 9 can be pushed by finger belly, negative pressure can be generated in the smoke drainage channel 4, under the drainage effect of the negative pressure, smoke generated in the abdominal cavity of the patient sequentially flows through the drainage port 25, the through hole 223 and the branch pipe 26 and then enters the smoke drainage channel 4, when the internal tissues of the abdominal cavity of the patient are blocked on the drainage port 25 under the action of negative pressure, the negative pressure in the drainage cavity 20 is gradually increased, the piston valve 22 moves towards the bearing rod 24, the sealing plug 28 is immersed in the through hole 223, at the moment, the air pressure between the drainage port 25 and the piston valve 22 leaks through the pressure relief port 21, in the process, the residual drainage port 25 is not hindered from conducting negative pressure drainage smoke, after the internal tissues of the abdominal cavity are separated from the drainage port 25, the piston valve 22 is reset under the action of the elastic force of the spring 23, and the whole smoke negative pressure drainage process is good in drainage effect through multi-azimuth drainage and cannot hurt the internal tissues of the abdominal cavity of the patient due to the action of the negative pressure.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
