Description

Technical Field

[0001] The utility model relates to the technical field of anorectal matching appliances, and in particular to an adjustable anorectal ligation device. Background Art

[0002] Hemorrhoid ligation is a common method for treating hemorrhoids, using a ligation device to block blood circulation to the excess foreskin, causing it to atrophy and necrotize, allowing the wound to heal on its own, thereby achieving the surgical goal of removing the excess foreskin. It has a very good therapeutic effect on common hemorrhoids. However, hemorrhoid ligation, currently performed clinically, is typically performed manually by the surgeon under local or other anesthesia. This is not only time-consuming and laborious, but also difficult to expose, and can easily cause bleeding and pain. To alleviate patient pain and surgical difficulty, various improvements have been developed, such as the negative pressure suction ligation method, which consists of a negative pressure nozzle, a negative pressure generator, and a connecting tube. The negative pressure generator draws the hemorrhoid into the nozzle while simultaneously placing a rubber ring around the base of the hemorrhoid, blocking blood flow and causing the hemorrhoid to necrotize and fall off due to ischemia. However, the negative pressure generator used in the current negative pressure suction ligation method is external.

[0003] However, the following problems exist during specific use: 1. The cover needs to be put on manually during use. Since sterile gloves are worn during the operation, it is difficult to put on the cover and the operation is inconvenient; 2. The excess parts need to be discarded and recycled as a whole after use.
