Wherein, the common laparoscope and the robot-assisted laparoscopic surgery have the advantages of small wound, quick recovery and the like. Laparoscopic surgery allows for an adequate surgical space and field of view by injecting CO2 to expand the natural or artificial cavities of the body. The electrosurgical generator can be used for cauterizing pathological tissues by using energy systems such as a high-frequency electrotome, an ultrasonic scalpel and the like in the operation process, the local generated ultrahigh temperature can exceed 2000 ℃ when the electrosurgical generator works, and smoke can be generated when organic matters such as proteins, adipose tissues, body fluid and the like are cauterized, and the smoke contains a large amount of toxic and harmful chemical substances and pollutes CO2 injected into a body cavity. The smoke generated by the carbonization of the histiocyte can lead to the fuzzy visual field of the operation, cause the pollution of the endoscope body, increase the times of endoscope wiping, prolong the operation time and easily cause the operation complication. To avoid smoke remaining in the patient's body cavity, the use of an aspirator to evacuate the contaminated gas is required, which can present two new problems: firstly, the discharge of the polluted gas can affect the air pressure fluctuation in the body cavity of the patient, influence the hemodynamics and influence the continuous implementation of the operation; secondly, the polluted gas is diffused in the operating room after being exhausted, and indoor air pollution is formed. Research proves that 95% of smoke aerosol particles are distributed in 0.3-2.5 micrometers (PM 0.3-PM 2.5) during electric cutting and electrocoagulation, the concentration of the smoke aerosol particles close to the mouth and the nose of medical staff is up to 3.6 hundred million/cubic meter, and the smoke aerosol particles damage the health of the medical staff.
