Collector of polyp removing gastrointestinal endoscope

Abstract

The invention discloses a collector of a polyp removing gastrointestinal endoscope. The collector of the polyp removing gastrointestinal endoscope comprises a suction main pipe (1) and a recovery bottle (2). One end of the suction main pipe (1) is connected with a port of a gastrointestinal endoscope host suction pipe and the other end of the suction main pipe (1) is connected with the recovery bottle (2). The recovery bottle (2) is further connected with a negative pressure suction pipe (3). The collector of the polyp removing gastrointestinal endoscope is characterized in that the suction main pipe (1) is connected with a branch suction pipe (4) provided with a bypass shunt. The inlet end (41) of the branch suction pipe (4) is provided with a three-way valve (5). The outlet end (42) of the branch suction pipe (4) is provided with a filtering net (6). The collector of the polyp removing gastrointestinal endoscope is simple in structure, low in manufacturing cost, convenient to install and use, capable of rapidly taking out a polyp, short in full-process operation time, needless of plugging and unplugging the endoscope by many times, capable of effectively relieving pain of patients and capable of ensuring integrity of a polyp sample and does not affect the operation of removing the polyp.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a polyp collector for gastrointestinal endoscopy, which is mainly used for gastrointestinal endoscopic interventional treatment in internal medicine of gastroenterology and endoscopic gastrointestinal polypectomy. Background technique [0002] For patients with gastrointestinal polyps, under gastroscopy or colonoscopy, the polyps need to be removed for pathological biopsy after the polyps are removed by high-frequency electrocuffs. Before the present invention was made, in the prior art, the endoscope main unit was usually connected with the aspirator, and when the gastroenteroscope was operated, the water and mucus in the cavity entered the aspirator through the suction hole. When the gastrointestinal endoscope removes polyps, it needs to be taken out by special grasping forceps or sucked on the mirror surface by negative pressure, and withdrawn with the gast...

Problems solved by technology

Chinese Utility Model Patent (Patent No. 02264531.4) discloses a polyp collector, which solves the above problems by placing a filter in the recovery bottle body. Although this patented technology solves the problem of repeatedly collecting specimens, it still has the following defects : The existence of the filter screen will affect the suction efficiency, and the filter screen continues to exist in this method, which affects the operation of removing polyps, and cannot be clinically promoted; the filter screen is continuously placed in the recovery bottle, and the polyps adsorbed on the filter screen will be attracted by the mucus , water, pollutants, etc. damage, affecting the final pathological evaluation; because the recovery bottle is often placed on the ground, it is difficult to conveniently determine whether the polyp has been successfully collected
