Technical Field

[0001] The utility model relates to an endoscopic ligation device and belongs to the technical field of medical equipment. Background Art

[0002] Esophageal varices are usually treated with endoscopic esophageal variceal ligation (EVL), which has the advantages of high safety, low risk, few postoperative complications, and simple operation. The common ligation device on the market consists of a control handle, a loading catheter (with a pull wire inside), a flushing connector, a cannula, a trigger pull box and a ferrule. The operation process is cumbersome and requires the coordinated operation of multiple operators. In addition, during the ligation process, if there is venous rupture and bleeding, accessories need to be replaced to stop bleeding, and the treatment process is slow. For this reason, the utility model is proposed. Summary of the invention

[0003] In view of the deficiencies in the prior art, the utility model provides an endoscopic ligation device, in which an airbag is connected to a syringe through a first cavity, the gas in the syringe is pushed into the airbag, and the ring at the front end of the airbag is pushed out, thereby completing the ligation operation; if venous rupture and bleeding occur during the ligation process, the connecting plug of the second cavity is connected to a water injection pump to realize the water injection function, and the third cavity is connected to a negative pressure suction device to realize the suction function.

[0004] The technical solution of the utility model is as follows:

[0005] An endoscopic ligation device comprises a transparent cap, an airbag, a ring, a first cavity, a second cavity and a third cavity. The transparent cap is in a hollow columnar shape and is made of transparent silicone, which is convenient for assembly with an endoscope and for observation. The second cavity and the third cavity are fixedly arranged on the transparent cap. The second cavity, the third cavity and the outer side of the transparent cap are interference-fitted with the ring. The airbag is fixedly arranged on the transparent cap inside the ring, and the airbag is connected to the first cavity.

[0006] Preferably, according to the utility model, the ends of the first cavity, the second cavity and the third cavity are respectively provided with a first connection port, a second connection port and a third connection port, and the first connection port, the second connection port and the third connection port adopt Luer connectors, which are convenient for corresponding connection to syringes, water injection pumps and negative pressure aspirators.

[0007] When in use, the head end of the endoscope is inserted into the transparent cap and fixed by interference fit, and the first cavity, the second cavity and the third cavity are firmly attached to the endoscope body with medical tape, and the syringe is filled with air and assembled with the first connecting port at the tail of the first cavity, and the water injection pump is connected to the second connecting port at the tail of the second cavity, and the negative pressure suction device is connected to the third connecting port at the tail of the third cavity, and then the endoscope is introduced into the esophagus, the selected varicose vein is observed, and it is sucked into the transparent cap through the suction of the endoscope, and the suction process is maintained, and the air in the syringe is pushed into the airbag. During the inflation process of the airbag, the ring is pushed to be released from the transparent cap, thereby completing the ligation of the varicose vein;

[0008] If the vein ruptures and bleeds during the observation process or the suction process, use the water injection function to find the bleeding point, and then use the negative pressure suction device to extract the blood and water mixture, aim the transparent cap at the vein at the bleeding point, and suck it into the transparent cap. Maintain the suction process, push the air in the syringe into the airbag, and push the loop to release from the transparent cap during the inflation of the airbag, thereby completing the ligation of the varicose vein bleeding site.

[0009] The beneficial effects of the utility model are:

[0010] The utility model has a simple structure and is easy to operate, reduces the number of operators, optimizes the operating steps, and the auxiliary cavity meets the suction and water injection requirements in an emergency state. BRIEF DESCRIPTION OF THE DRAWINGS
