Collection device for resected specimen under digestive endoscopy

Abstract

The invention provides a device for collecting resected specimens under a digestive endoscopy, and relates to the technical field of medical apparatuses and instruments. The invention discloses a device for collecting resected specimens under a digestive endoscope. The device comprises a stretching assembly, a cutting assembly and a collecting assembly, the cutting assembly includes an inner mounting ring, an outer mounting ring, and a plurality of cutting blades. And the multiple cutting blades are rotationally arranged on the inner mounting ring, and the multiple cutting blades form an iris flower structure. The outer mounting ring and the inner mounting ring are located on the same plane, and the inner mounting ring is located in the outer mounting ring. The cutting blade and the outer mounting ring are both provided with arc-shaped connecting rods, one ends of the arc-shaped connecting rods are rotationally connected with the outer mounting ring, and the other ends of the arc-shaped connecting rods are rotationally connected with the cutting blade. The collecting assembly is arranged on the inner mounting ring; the stretching-in assembly is connected with the cutting assembly. According to the invention, the cutting of the focus can be accurately and rapidly completed at one time, and the focus is collected.

Description

technical field [0001] The invention relates to the technical field of medical devices, and in particular, to a collection device for excision specimens under digestive endoscope. Background technique [0002] Endoscopic treatment technology involves the early resection of superficial malignant tumors of the gastrointestinal tract and the debulking treatment of some advanced malignant tumors, as well as the tissue of gastrointestinal lesions that cannot be clearly diagnosed by endoscopic biopsy, etc. Most of the endoscopic specimens are recovered. The device is very simple. For example, gauze is used to block the suction hole of the endoscope. After negative pressure suction, the specimen will stay on the gauze and then be recovered. The patent name is: a patent for a device for collecting specimens for excision under digestive endoscope (CN201910473626.7), which discloses a device for collecting specimens for excision under digestive endoscope, which includes a handle and a...

AI Technical Summary

Problems solved by technology

The combined cutting effect of the four cutting rods is not good, which may easily lead to the inability to effectively cut the lesion at one time during the cutting process

As a result, it is easy to cause part of the lesion to be connected with the human body after cutting, and it is necessary to control the four cutting rods to close together for continuous extrusion and excision, which may easily lead to poor excision effect
