Description

Fume extractor and drainage equipment of laparoscopic surgery Technical Field The utility model relates to the technical field of medical consumables, in particular to a smoke exhausting device and drainage equipment for endoscopic surgery. Background In recent years, with the rapid development of medical technology, modern surgical tools such as electrosurgical devices, laser cutters, and ultrasonic surgical cutters are widely used in clinical practice, greatly improving the operation accuracy and efficiency of surgical operations. However, these advances have hidden a non-negligible problem in that the potential threat to health of medical personnel by surgical smoke generated during the surgical procedure is becoming increasingly pronounced. The surgical smoke is mainly composed of 95% water or water vapor and 5% cell debris in the form of particles, and the 5% particle components include blood and tissue debris, harmful chemical components, active viruses, active cells, inactive particles, mutation-inducing substances, etc., seriously threaten physical and mental health of doctors and patients, and affect the surgical field of doctors. The protection of the prior art to the operation smog mainly has three kinds: Firstly, a smoke-removing electric knife pen is used, and is characterized in that an air suction device is integrated on an electric knife head, so that generated smoke can be immediately sucked in the operation process, and the influence of the smoke on the environment is reduced; Secondly, an operating room ventilation system is applied, and an efficient air purifier is usually required to ensure the air quality in an operating room, and the system depends on a smoke absorbing and discharging system arranged in the operating room, and the system discharges waste gas outside the operating room through an exhaust pipeline arranged in the operating room, but the method is high in cost and complex in installation process, and can only realize the discharge of the waste gas in the air in the operating room, so that smoke in the abdominal cavity of a patient cannot be immediately removed, further the view of an operation is blocked, and the operation flow is influenced; Thirdly, by means of personal protection of medical staff, for example, wearing a protective mask, smoke can be reduced to be inhaled into a human body, harm to the human body is reduced, but the protective effect of the method is limited, smoke in an operating room, particularly in the abdominal cavity of a patient, cannot be effectively removed, and accordingly the operation vision is adversely affected. In summary, how to solve the problem of interference of surgical smoke to the surgical procedure in different surgical procedures is a urgent problem for those skilled in the art.
