Abstract

The invention discloses a smog removal device for laparoscopic surgery. The device comprises filtering and drying equipment and pumping equipment, wherein an exhaust port of one trocar is connected with the filtering and drying equipment and then connected with the pumping equipment, the exhaust equipment is then connected with an exhaust port of the other trocar, the pumping equipment is started to pump out gas in an abdominal cavity, and the gas is delivered back to the abdominal cavity after being filtered, dried and sterilized. By means of the device, toxic and harmful particles and components such as cell debris, impurities, aerosol, vapor and the like in surgery smog can be effectively removed, carbon dioxide in bodies is not absorbed, the gas purification rate is approximately 100%, so that the clear field of view can be kept for the surgery, the surgery can be conducted smoothly, the surgery time is effectively shortened, surgery risks are reduced, and the safety of patients is guaranteed; the gas in the abdominal cavity is recycled, pressure in the abdominal cavity is guaranteed, the smog in the abdominal cavity can be removed under the condition that the surgery is not stopped, the surgery time is shortened, and the surgery is conducted smoothly.

Description

technical field [0001] The invention belongs to the field of medical auxiliary equipment, in particular to a smoke purification and removal device in laparoscopic surgery. Background technique [0002] Laparoscopy is an instrument with a miniature camera. Laparoscopic surgery is performed using a laparoscope and related instruments: using a cold light source to provide illumination, inserting a laparoscopic lens (3-10 mm in diameter) into the abdominal cavity, and using a digital The camera technology enables the images captured by the laparoscopic lens to be transmitted to the post-stage signal processing system through the optical fiber, and displayed on the dedicated monitor in real time. Then the doctor analyzes and judges the patient's condition through the images of different angles of the patient's organs displayed on the monitor screen, and uses special laparoscopic instruments to perform the operation. [0003] Laparoscopic surgery mostly uses 2 to 4 holes, one of ...
