Description

Multiple polyp collector

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a multiple polyp collector.

Background

Polypoid lesions of the digestive tract refer to neoplasms growing on the inner surface of the digestive tract of a human body, and the common properties are hyperplasia, inflammation, hamartoma, adenomatosis, tumorous and the like. Polyps are mostly one of benign tumors, and clinically manifest inflammatory polyps, adenomatous polyps and certain gastrointestinal polyp syndromes, but these lesions are benign, some of which have a tendency to malignant changes. The medical science generally names the site of occurrence. Such as those growing on the stomach wall are called "gastric polyps", those in the intestinal lumen are called "intestinal polyps", and if there are more than two polyps at a certain location, they are also called "polyps with multiple properties".

The endoscopic (gastroscope, enteroscope) resection of polyps in the digestive tract is a very effective measure for preventing canceration, and a polyp collector is an instrument for collecting removed polyps during rectal examination and polyp examination. A multiple polyp enteroscopy suction collector disclosed in Chinese patent publication No. CN216090436U is used for collecting polyps found and removed in operation or enteroscopy, and uniformly transmitting the polyps to a slicing test after the detection is completed. By dividing the interior of the device into a plurality of cavities, each cavity can be used as a separate containment compartment for collecting a plurality of polyps. When the device is used, one end of the collector is connected with the negative pressure suction equipment, the other end of the collector is connected with the suction port of the endoscope which leads to the body, when the polyp needs to be recovered, the polyp is resected, then the negative pressure suction equipment is opened, and the resected polyp is sucked into the collector through the pipeline of the suction port of the endoscope. When a plurality of samples are required to be collected, the inner cavity can be driven to rotate to a designated position only by rotating the cup cover so as to collect polyps for a plurality of times.

Through clinical feedback, currently mainstream polyp collectors suffer from certain drawbacks: firstly, the structure is complex, after polyps are collected to the accommodating grid, the accommodating grid can be taken out only after the polyp collector is completely disassembled, and the structure is complex and the manufacturing cost is high; secondly, in the operation process, a doctor needs to look over the service condition of the collector accommodating grid at a low head in addition to observing the operation process, and the cup cover is rotated in time to switch the accommodating grid, so that the operation steps are complicated.
