The specific process of the surgery is as follows: a cold light source is used to provide illumination, a laparoscope lens (3-10 mm in diameter) is inserted into the abdominal cavity, digital camera technology is used to make the image captured by the laparoscope lens transmitted to a background signal processing system through optical fibers, and the image is displayed on a special monitor in real time, then medical staff analyzes and judges the patient's condition by the images of the patient's organs in different angles displayed on the monitor screen, and performs surgery by using special laparoscopic instruments. The laparoscopic surgery is usually performed by 2-4 hole operation method, one of which is opened on the navel of the human body to avoid leaving a long scar on the abdominal cavity of the patient, and after recovery, only 1-3 linear scars of 0.5-1 cm are left on the abdominal cavity, which can be said to be a surgery with small wound and little pain. The multi-channel single-hole laparoscope puncture device is commonly used in minimally invasive laparoscopic surgery. The multi-channel single-hole laparoscope puncture device improves the previous 3-4 hole instrument introduction into one hole multi-instrument introduction, which not only reduces the trauma of the patient, but also produces the effect of no scar on the incision, and is deeply welcomed by doctors and patients. The multi-channel single-hole laparoscope puncture device mainly comprises a multi-hole operation platform and a channel pipe (incision protection sleeve) connected with the multi-hole operation platform, and the multi-hole operation platform and the channel pipe are connected through a sealing structure.

[0003] At present, the multi-channel single-hole laparoscope puncture device on the market is only provided with a gas input pipe on the multi-operation platform for inputting surgical gas, but during the surgery in the human body by using surgical instruments by medical staff, burning smoke and other harmful gases are generated, which affects the picture captured by the laparoscope lens and the observation angle of the medical staff, some companies consider this problem and simultaneously provide a gas output pipe on the multi-operation platform to exhaust the burning smoke and other harmful gases in the incision protection sleeve, but the effect on the harmful gases escaping to the outside of the incision protection sleeve is limited, and the harmful gases in this part will be in the patient's body, which will have a potential impact on the patient's health.

[0004] After retrieval, China invention patent: single hole multi-channel laparoscopic surgery device (publication number: CN111839617A, publication date: 2020.08.25), the application includes a multi-channel surgery operating table and a incision protection sleeve, the multi-channel surgery operating table includes: a flexible body with an outlet, the outlet end of the flexible body is sealingly connected with the inlet end of the incision protection sleeve, a taking port and an air inlet / outlet are provided on the side wall of the flexible body; a plurality of introduction channels, the plurality of introduction channels are arranged on the flexible body and are in communication with the inside of the flexible body, and the plurality of introduction channels are arranged at intervals; a taking bag, which is accommodated in the taking port, and the inlet end of which is sealingly connected with the taking port; a locking cover, which is detachably connected with the taking port, for closing the taking port. The scheme sets an air inlet / outlet for inputting surgical gas and discharging burning smoke and other harmful gases generated in the incision protection sleeve during surgery, but does not consider how the burning smoke and other harmful gases escaping from the incision protection sleeve are discharged, in addition, the burning smoke and other harmful gases discharged through the air inlet / outlet are directly discharged into the air outside the operating room, which affects the sterile environment of the operating room and the health of medical staff.
