Ligature forceps for hemorrhoid operation

Technical Field

The present disclosure relates to the technical field of medical instruments, and in particular, to ligature forceps for hemorrhoid surgery.

Background

Hemorrhoids are a common anorectal disease including internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids. For severe internal hemorrhoids, surgical treatment is often performed by ligation, i.e. by blocking the blood supply to the base of the hemorrhoid by ligating it, which causes anoxic necrosis of the hemorrhoid. The hemorrhoid is removed and the wound surface basal part is repaired simultaneously, and when the hemorrhoid is removed, new granulation tissues rapidly fill the wound surface to achieve the cure purpose.

In the ligation operation process, the hemorrhoid is sleeved by an operation wire, but the internal hemorrhoid is inconvenient to use and easy to fall off due to the deeper growth position of the internal hemorrhoid, the operation field is often required to be enlarged, pain is caused to a patient, and the postoperative recovery time is prolonged.
