Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and in particular to an anorectal ligation device which is easy to operate. Background Art

[0002] Band ligation, developed from traditional Chinese medicine ligation therapy, involves placing a specially designed rubber band around the base of the hemorrhoid or the mucosa above it, 1.5 to 3 cm above the dentate line. The band tightens and strangles the hemorrhoid, blocking its blood supply or reducing venous reflux. This reduces congestion, hypertrophy, or blood stasis, leading to ischemia, atrophy, and necrosis. The banded tissue gradually falls off, allowing the wound to heal and heal. It is one of the most effective non-surgical treatments.

[0003] The conical portion of the existing anorectal ligation device that is easy to operate is usually sleeved inside the ligation port to prevent external dust, viruses and dirt from entering the ligation port when the ligation device is not in use. However, this sleeve connection method is relatively compact, which is not conducive to the user to quickly remove the conical portion from the ligation port, thereby slowing down the ligation work efficiency. In addition, they all adopt a horizontal and vertical structure, which is not convenient for multi-angle operation. Utility Model Content
