Abstract

The invention relates to the field of medical suction or drawing instruments, and particularly discloses an exhaust device for endoscopic surgery. The exhaust device comprises a body, wherein a partition plate is arranged in the middle of the body, the partition plate divides the internal space of the body into a first cavity and a second cavity which are mutually independent, the top end of the first cavity is provided with a first pipe body and a second pipe body, the top end of the second cavity is provided with a third pipe body and a fourth pipe body, one end of the first pipe body and one end of the third pipe body both extend to the bottom end of the body, one end of the second pipe body and one end of the fourth pipe body both extend to the top end of the body, the second pipe body is connected with the third pipe body, and a filter element is arranged in the second cavity. The invention further discloses an exhaust method for the endoscopic surgery. According to the invention, a filter element can filter harmful smoke containing particulate matters such as PM2.5 and PM10 in gas, meanwhile, peculiar smell can be removed, and the healthy environment of the medical staff in the surgery process is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical suction or pumping instruments, in particular to an exhaust device for laparoscopic surgery. Background technique [0002] Laparoscopic surgery has the advantages of small trauma, quick recovery, safety, and beauty. It has been widely used in clinics. The operation needs to form enough space through artificial pneumoperitoneum to facilitate peeping and operation. Carbon dioxide is commonly used in laparoscopic surgery to establish pneumoperitoneum. For example, in endoscopic full-thickness resection (EFTR), the endoscope sends gas through the carbon dioxide gas pump during diagnosis and treatment, so that the intragastric pressure is greater than the intraperitoneal pressure, stretching the gastric wall structure, providing Good surgical field of view and operating space, resection through endoscope and surgical instruments. During the operation, the endoscopist needs to continuously send air thr...
