In recent years, with the rapid advancement of medical device technology and the continuous progress of surgical concept, the proportion of laparoscopic surgery accounts for more than half of the surgical operation. In general, almost all general surgical operations, such as operations on liver, gall bladder, pancreas, spleen, gastrointestinal tumors, abdominal hernia repair, etc., and various operations on the urogenital system, such as operations on kidney, prostate, bladder tumors, hysterectomy, etc., can be performed laparoscopically; the principle is that a plurality of operation holes are established through the abdominal wall of a patient, a laparoscope lens with cold light source illumination and a long rod-shaped laparoscope operation instrument rod are placed after an artificial pneumoperitoneum is established, an operator operates the instrument rod outside the patient body to perform various operation operations in a closed abdominal space by observing real-time pictures transmitted to a display by the laparoscope lens, and the aim of minimally invasive treatment is fulfilled by 'precise dissection' under an enlarged visual field; the laparoscopic surgery is becoming the development direction of the surgery field with its rapid trend because of its numerous advantages of small trauma, fast postoperative recovery, short hospitalization time, less pain to the patient, etc. However, the specific implementation of the laparoscopic surgery at present has an unavoidable problem, which is that a large amount of water vapor or smoke is generated when various energy platforms (such as electrocoagulation, ultrasonic knife, etc.) are used for tissue cutting and coagulation in the surgery, so that the lens is easily blurred, a light person needs to pause the surgery until the lens naturally recovers to be clear, a heavy person needs to completely withdraw the lens from the abdominal cavity, and the lens is placed again after being cleaned and wiped outside the body, so that the operation is interrupted and the surgery time is prolonged. Clinically, this type of condition occurs commonly, especially more frequently for inexperienced handpieces, and not only affects the continuity of the surgery, but also the safety of the surgery due to the unclear field of vision of the operator. The only coping method at present is that a common suction apparatus used by an operator or an assistant is put in through an abdominal wall operation hole to suck away smoke, but the suction apparatus needs to occupy one operation hole, so that the surgical instrument rod and the suction apparatus are frequently alternated in the operation hole, the time is delayed, and the ideal operation field exposure cannot be achieved.
