Ligation device and closing device for digestive endoscope

Abstract

The invention provides a ligator for a digestive endoscope and a closing device, and relates to the technical field of medical equipment. A rope body placing tube is arranged in the ligation adsorption tube head, and a searchlighting end is further arranged in the ligation adsorption tube head; the device has the effect of adsorbing and positioning a polyp, the polyp is adsorbed and positioned and then is matched with a ligation ring to act, so that the ligation ring can be more accurately connected to the bottom of the polyp in a sleeving mode, and the probability that the polyp moves in the sleeving process, so that positioning of the ligation ring is affected is reduced; according to the ligation device, the length of the ring body can be automatically shortened, the ring body is not prone to falling off, and the problems that for an existing traditional ligation device for the digestive endoscope, a ligation ring is inconvenient to position on a polyp, the polyp is prone to moving, a certain obstacle is caused to the ring sleeving action of the ligation ring, operation is inconvenient, and the ligation ring lacks an anti-skid and fastening structure and is prone to falling off are solved. And the treatment effect is easily affected due to the fact that the ligation ring is too long.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a ligation device and a closing device for digestive endoscopy. Background technique [0002] Among digestive tract tumors, gastric cancer and colorectal cancer rank the second and fourth in the incidence rate of tumors in my country. Some early gastric cancer and colorectal cancer can be treated by endoscopy in early treatment, which has the advantages of small wound surface. In the non-exposure full-thickness resection, when the superficial lesions are removed, there is currently a closure device, namely the Olympus ligation ring, which is made of nylon material, which can achieve the closure of the superficial lesions. [0003] However, as far as the current traditional ligation device for digestive endoscopy is concerned, the positioning of the ligation ring on the polyp is inconvenient, and the polyp is easy to move, which causes certain obstacles to the snare actio...

Problems solved by technology

[0003] However, as far as the current traditional ligature device for digestive endoscopy is concerned, it is inconvenient for the ligature ring to be positioned on the polyp. Solid structure, easy to fall off, if the ligation ring is too long, it may affect the treatment effect
