Minimally invasive-type automatic ligation device for hemorrhoids

Abstract

The invention relates to a minimally invasive-type automatic ligation device for hemorrhoids. The main body of the ligation device takes the shape of a gun; the ligation device comprises a gun housing, a connecting mouth (1), a negative pressure suction pipe (2), a movable pushing pipe (3), a pushing block (4), a pushing sleeve fixing seat (7), a suction nozzle fixing seat (8), a pushing sleeve (11), a suction nozzle (12), a negative pressure air cylinder, a negative pressure handle (18), a pushing handle (19) and a release valve (23); two negative pressure connecting pipes (14) are arranged on the cylinder body (16) of the negative pressure air cylinder; the release valve (23) arranged in the handle of the gun-shaped ligation device comprises a valve body; a release valve first connecting pipe (21) and a release valve second connecting pipe (22) are arranged on the valve body; the connecting mouth (1) is connected with the release valve second connecting pipe (22); the release valve first connecting pipe (21) is connected with one negative pressure connecting pipe (14) through a check valve; and the other negative pressure connecting pipe (14) is connected with another check valve. The automatic ligation device realizes the continuous negative pressure, and has a negative pressure eliminating device, so that the use is convenient, safe and reliable.

Description

Technical field: [0001] The invention relates to a hemorrhoid ligation device, in particular to a minimally invasive automatic hemorrhoid ligation device. It belongs to the technical field of medical equipment. Background technique: [0002] Existing treatment of hemorrhoids, especially for the treatment of internal hemorrhoids, mostly adopts the treatment method of surgical excision, which is expensive, and the postoperative wound surface is relatively large, which increases the pain of the patient and increases its psychological burden. In order to overcome the above-mentioned defects, hemorrhoid ligation devices have been used clinically. The hemorrhoid ligation device absorbs the hemorrhoid lesion tissue through negative pressure, and then ligates it with a rubber ring. The tissue under the rubber ring will gradually fall off due to lack of blood circulation, and will be excreted through the stool. [0003] Most of the hemorrhoid ligation devices currently in use are s...

Problems solved by technology

[0004] First of all, when the trigger is pulled, the negative pressure is once to the end, and the negative pressure cannot be sustained. Once the hemorrhoid lesion is not completely sucked into the suction nozzle at one time, it needs to be re-operated, which increases the pain of the patient. For some larger hemorrhoid lesions, it is very difficult It is difficult to inhale at one time, and surgical resection is bound to be performed, which will increase the patient's pain and increase their psychological burden

[0005] Secondly, after the hemorrhoid ligation device is ligated, there is a lack of negative pressure elimination facilities, so that the device and the diseased tissue cannot be separated by themselves, and it needs to be separated by artificial force, which will cause varying degrees of damage to the surrounding and rectal mucosal tissue, and is prone to Hazards of bleeding, infection and postoperative complications

[0006] Third, the traditional hemorrhoid ligation device does not have its own light source, and it needs to be equipped with other light sources during the operation, which is cumbersome to operate
