Technical Field
[0001] The present invention relates to the technical field of medical devices, in particular to a laparoscopic double-lumen aspirator. Background Art
[0002] A laparoscope is similar to an electronic gastroscope and is a medical device equipped with a miniature camera. Laparoscopic surgery is performed using a laparoscope and its related instruments. It consists of five basic systems: a laparoscopic video surveillance system, a CO2 pneumoperitoneum system, an electrocuting system, an irrigation-suction system, and surgical instruments. The laparoscopic video surveillance system includes a laparoscope, a light source and optical path, a miniature camera, a camera converter, a monitor (TV), an automatic cold light source, and a video recorder. Laparoscopes commonly have 0° and 30° viewing angles. During laparoscopic surgery, the laparoscopes commonly used are single-channel, meaning that the electrocoagulation knife and the suction device act separately. The laparoscopes need to be operated separately, which greatly affects the efficiency of the surgery. To this end, we propose a laparoscopic double-lumen suction device. Summary of the Invention
