Polyp pathology sample intercepting device

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a polyp pathological specimen interception device.

Background

Polyps are neoplasms that grow on the surface of human tissue, and modern medicine generally refers to neoplasms that grow on the surface of human mucosa as polyps. Including proliferative, inflammatory, hamartoma, adenoma, and other tumors. Polyps are one of benign tumors, and are clinically manifested by inflammatory polyps, adenomatous polyps, and certain gastrointestinal polyp syndromes, some of which are benign but have a propensity to malignant lesions. To exclude if a malignant lesion has occurred, a biopsy needs to be taken in time.

In the prior art, endoscopic polyp removal is a common treatment means in digestive endoscopy diagnosis and treatment, and in the surgical process of removing a plurality of polyps, nurses are required to cooperate to intercept the polyps so as to carry out biopsy on the polyps. However, in actual operation, there may be a problem that a nurse cannot match the negative pressure suction bag in place, and directly sucks the specimen into the negative pressure suction bag, so that the specimen is lost, and adverse events occur. At present, a common specimen interception mode is to place a non-spinning cloth in front of a negative pressure connection suction port of the front section of an endoscope light guide insertion part, and then connect a negative pressure connecting pipe with the suction port, if interception is successful, then the negative pressure connecting pipe needs to be separated, an acquired specimen on gauze is taken down, and then a negative pressure pipeline is reconnected, so that the operation process is extremely inconvenient and the operation is inconvenient to smoothly carry out. For polyp extraction at a plurality of positions or large polyp extraction which needs to be cut for a plurality of times, the negative pressure connecting pipe needs to be frequently pulled out, the sucked polyp is taken down, the position of the gauze is adjusted, and then the negative pressure connecting pipe is connected, so that the whole process is troublesome to operate.
