Abstract

The invention discloses an excision device for intestinal polyps. The excision device comprises an intubation tube, wherein a first endoscope body is arranged at the tail end of the intubation tube, afirst air tube is arranged on the intubation tube in a sleeving manner, a fixed block of a cylindrical structure is arranged at one end of the first air tube, a cavity is formed in the fixed block, two circular cone rods are both located in the cavity of the fixed block, a fixed plate is arranged between the two circular cone rods, and telescopic tubes are arranged on two sides of the fixed plate; internal supporting assemblies with arc-shaped structures are arranged on two sides of the fixed block; a cutting assembly is further arranged on the fixed block, and a second endoscope body is further arranged on the cutting assembly; a second arc-shaped plate is arranged between the two circular cone rods on the first air tube, two ends of the second arc-shaped plate are connected with the twocircular cone rods respectively, the central position of the second arc-shaped plate is further connected with the cutting assembly, and when the two circular cone rods are close in the direction ofthe fixed plate, the second arc-shaped plate can push the cutting assembly to extend out in the radial direction of the fixed block.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a resection device based on intestinal polyps. Background technique [0002] Polyps refer to the growths on the surface of human tissues. Modern medicine usually refers to the growths on the surface of human mucous membranes as polyps, including hyperplastic, inflammatory, hamartoma, adenoma and other tumors. Polyps are a kind of benign tumors. The clinical manifestations are mostly inflammatory polyps, adenomatous polyps and some gastrointestinal polyp syndromes. Although these lesions are benign, some of them have a tendency to become malignant. Those cysts that grow under the skin, lipomas in adipose tissue, and fibroids in muscles can also cause bulges on the body surface, but they do not belong to the category of polyps. In medicine, it is generally named according to the part where it appears. For example, those that grow on the vocal cords are called "vocal cor...
