Description

Colonoscope specimen collector

Technical Field

The utility model relates to the technical field of medical treatment, concretely relates to colonoscope sample collector.

Background

Colonoscopy is an important examination mode for screening colorectal cancer, and pathological results obtained by endoscopic extraction of polyps are important links. Currently, there are two methods for obtaining polyp specimens under a colonoscope clinically: (1) for large polyps of more than 1cm, a snare can be used for looping and taking out along with a scope; (2) small polyps below 1cm are difficult to use with a snare, and are clinically removed by covering the colonoscope external port with wet gauze and suction under negative pressure. The existing polyp specimen acquisition mode has certain defects: (1) in the process of sucking tissues to the wet gauze through negative pressure suction, the condition that the specimen is sucked into the suction bottle to cause difficulty in collecting the specimen often occurs; (2) for polyps with larger volume and far away from the anal edge, the snare can not sleeve the polyps out integrally; the polyp is sucked into the wet gauze by negative pressure after being crushed for several times, the gauze needs to be replaced for several times, and the endoscope treatment time is prolonged. How to improve the specimen acquisition mode in the colonoscope has very important significance on shortening the operation time and improving the detection rate.
