Collection device for resected specimen under digestive endoscopy

Abstract

The invention relates to the technical field of medical instruments, and discloses a digestive endoscopy resection specimen collecting device. The device comprises an insertion tube, an outer cylinder is fixedly mounted at the tail end of the insertion tube, one end of the outer cylinder is open, and a connecting plate is slidably arranged on the inner wall of the open end of the outer cylinder; a first sliding plate and a second sliding plate are fixedly mounted at the left and right ends of the right side of the connecting plate; after the first clamping block gradually gets close to the second clamping block and cuts off the specimen tissue, the first clamping block is continuously controlled to move rightwards, at the moment, the first clamping block also pushes the second clamping block to move rightwards, the second clamping block moves rightwards and can push the piston to move rightwards through the push rod, the piston moves rightwards to push and extrude the RNAlater solution in the storage cavity, the RNAlater solution is extruded and can be conveyed into the collecting bag through the conveying pipe, the first one-way valve and the connecting hose, so that the specimen tissue is soaked, the activity of the specimen tissue is guaranteed, the storage time of the specimen tissue is prolonged, and the storage quality of the specimen tissue is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for collecting resection specimens under digestive endoscopy. Background technique [0002] Endoscopic treatment techniques involve early resection of superficial digestive tract malignant tumors under endoscopy, debulking treatment of some advanced malignant tumors, and gastrointestinal lesions that cannot be clearly diagnosed by endoscopic biopsy. With the development of science and technology, digestive endoscopy technology has made great progress, and the design of the specimen recovery device under digestive endoscopy is becoming more and more ingenious, and its functions are becoming more and more abundant; [0003] For example, the Chinese patent announcement number is: CN108403155A invention patent, which just provides a kind of resection specimen collection device under digestive endoscopy, including a base, the left side of the base is rotatably connect...

AI Technical Summary

Problems solved by technology

[0005] When the above-mentioned sample collection device collects the sample tissue by using negative pressure, the sample tissue is easily damaged when it moves under the action of negative pressure, thereby affecting the later pathological analysis. At the same time, the above-mentioned sample collection device cannot effectively collect the sample tissue. Preservation cannot guarantee the activity of the specimen tissue, which affects the storage time and quality of the specimen tissue;
