Anti-backflow laparoscope washing aspirator

Abstract

The invention discloses an anti-backflow laparoscope flushing aspirator which comprises a flushing connector, an aspiration connector, a control valve and a connecting pipe; the connecting pipe comprises an outer pipe, an inner pipe and an anti-backflow device, and the anti-backflow device comprises a bottom ring, a sliding block, a connecting component, an elastic component and a baffle; a suction hole is formed in the end, close to the backflow preventing device, of the outer pipe; the baffle is arranged in an inner hole of the bottom ring and comprises two semicircular baffle bodies; a baffle groove is formed in the inner side wall of the bottom ring; two sliding block holes are further formed in the inner side wall of the bottom ring, and communicating strip holes are formed between the sliding block holes and the baffle grooves; and sliding blocks and elastic components are arranged in the two sliding block holes. According to the technical scheme, after flushing is completed, the sliding block and the baffles are pushed to the inner hole under the action of the elastic force of the elastic component, the two semicircular baffles are spliced to seal the inner hole, liquid in the inner tube cannot flow out, and therefore the situation that residual liquid in the inner tube flows out and influences the surgical field is prevented.

Description

technical field [0001] The invention relates to the technical field of laparoscopic flushing and suction equipment, in particular to a laparoscopic flushing suction device for preventing reflux. Background technique [0002] With the advancement of science and technology, laparoscopic surgery has developed greatly, and laparoscopy with minimally invasive effects plays an important role in the treatment and diagnosis of celiac diseases. Laparoscopic surgery is popular among patients because of its advantages of small incision, less pain, faster recovery, and less postoperative scar. In laparoscopic surgery, medical personnel have to complete a series of actions, including cutting and stripping, electrocoagulation to stop bleeding, flushing, blood sucking, etc. Among them, peritoneal washing must be performed during the operation, and then the lotion is sucked away. [0003] However, in the prior art, the water pipe (suction tube and / or flushing tube) of the laparoscopic flus...
