Description

Hemorrhoid surgical instrument assembly

Technical Field

The present disclosure relates to the technical field of medical devices, and in particular, to a hemorrhoid surgical device assembly.

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, the operation field is often required to be enlarged, pain is caused to a patient and the postoperative recovery time is prolonged, when the operation field is enlarged by using the existing dilator, the existing dilator is often automatically displaced under the influence of muscle movement of the patient, and the internal hemorrhoid is required to be held and fixed by a doctor, so that inconvenience is brought to the operation.
