Technical Field
The invention relates to the technical field of medical equipment, in particular to resection equipment for application of polyps in intestinal tracts of patients.
Background
Polyps refer to neoplasms growing on the surface of human tissue, and modern medicine generally refers to neoplasms growing on the surface of human mucosa as polyps, including hyperplastic, inflammatory, hamartoma, adenomas and other tumors. Polyps are one of the benign tumors, and inflammatory polyps, adenomatous polyps and certain gastrointestinal polyp syndromes are frequently observed in clinical manifestations, and although these lesions belong to benign, part of them have a malignant tendency. Cysts that grow under the skin, lipomas in adipose tissue, intramuscular myomas, etc., can also cause elevations in the body surface, but are not in the polyp category. It is generally medically named by the site of occurrence. For example, the term "vocal cord polyp" is grown on the vocal cords, the term "gastric polyp" is found on the stomach wall, the term "intestinal polyp" is found in the intestinal lumen, and so on. If there are more than two polyps in a certain part, it is also called "multiple polyps". At present, when polyps in intestinal tracts are cut off, the polyps in the intestinal tracts cannot be cut off quickly by a traditional polyp cutting tool because the intestinal tracts wriggle and the inner layer is of a fold structure.
