Laparoscopic surgery relies on injecting carbon dioxide gas through a pneumoperitoneum device to create a volume of the abdominal cavity, providing a visual operating environment for the physician. The performance of the pneumoperitoneum system is critical to maintain pressure stability during surgery, prevent abdominal collapse and maintain a clear view. However, during surgery, a great deal of smoke is generated due to the operation such as electrocoagulation, electrotomy and the like, and the smoke is accumulated in the surgical field to seriously influence the operation of doctors, so that the operation precision is reduced, the key tissue structure is possibly covered, and the surgical risk is increased. Most of the existing pneumoperitoneum equipment adopts a manual smoke discharging operation mode, and an intelligent recognition and active cleaning mechanism is lacked. Pressure regulation of a traditional pneumoperitoneum system depends on a medical staff to adjust an air inlet valve according to experience, the pressure change of an abdominal cavity cannot be responded in real time, and in the smoke removal process, the pressure control is unstable.
