Problems solved by technology

The traditional single-shot ligation device at home and abroad usually uses silk thread to pull the inner cylinder of the ligation to retract and release the ligation ring. Although the structure is simple, it needs to repeatedly assemble the matching ring by hand, and the operation is complicated. The use efficiency is low, and a thicker traction wire needs to be used to pass through the endoscopic biopsy channel, which directly affects the negative pressure attraction and therapeutic effect during treatment
In addition, because this kind of wire traction ligation device still needs to be pulled hard to make the front ligation inner cylinder retreat back into the outer cylinder until the ligation ring is detached, the wire will slip when pulling, and the front end of the endoscope is at 180° It is difficult to operate in the flipped state, so it cannot be applied to the ligation treatment of gastric varicose veins, and the treatment range is limited, so it has been eliminated at present
Although the multi-shot continuous ligation device produced in the United States

Abstract

The invention discloses an air bag driving sleeving and binding device and relates to a medical appliance. The device is provided with a sleeving and binding inner pipe, a sleeving and binding outer pipe, a connecting catheter, an injector interface, a sleeving and binding ring, a sleeving and binding ring bracket barrel, a sleeving and binding ring mounting plate, an injector and an endoscope, wherein the sleeving and binding ring sleeves the outermost side of the front part of the sleeving and binding inner pipe; the sleeving and binding outer pipe wraps the outer side surface of the sleeving and binding inner pipe; the front part of the sleeving and binding outer pipe is thin and normally in a contracted state; the sleeving and binding outer pipe is tightly attached to the outer side surface of the sleeving and binding inner pipe; the front end of the sleeving and binding outer pipe is open or closed; the rear end of the sleeving and binding outer pipe is continuously thickened to form a connecting pipe which can sleeve the front end of the endoscope; the sleeving and binding outer pipe is communicated with an injector interface of the injector through the connecting catheter; the sleeving and binding ring bracket barrel is placed in a circle hole in the sleeving and binding mounting plate, the sleeving and binding ring bracket barrel can freely slide up and down in the circle hole. Efficient, convenient, safe and rapid sleeving and binding treatment on various digestive tract diseases with adaptive symptoms can be achieved. The structure is simpler, the processing and the manufacturing are easier, and the operation is easier and simpler.

Description

technical field [0001] The invention relates to a medical device, in particular to an air bag-driven ligation device used under direct vision of an endoscope. Background technique [0002] Ligation of esophageal and gastric varices under direct vision under endoscopy is one of the most efficient and preferred treatment methods recognized worldwide. The traditional single-shot ligation device at home and abroad usually uses silk thread to pull the inner cylinder of the ligation to retract and release the ligation ring. Although the structure is simple, it needs to repeatedly assemble the matching ring by hand, and the operation is complicated. The use efficiency is low, and a relatively thick traction wire needs to be used to pass through the endoscopic biopsy channel, which directly affects the negative pressure attraction and therapeutic effect during treatment. In addition, because this kind of wire traction ligation device still needs to be pulled hard to make the front ...
