AI Technical Summary
In high-level anal fistula surgery, removing the fistula requires removing the muscles of the puborectal ring, which can lead to fecal incontinence and anal displacement. Traditional rubber bands tightening the puborectal ring can generate centripetal cutting force, resulting in postoperative keyhole-like anal deformity.
Design an adjustable continuous traction hanging device for high-level anal fistula, including a fixing belt, an adjusting belt, a fitting seat and a traction unit. The traction force of the rubber band can be adjusted by the adjusting knob and traction hook on the traction unit, converting the centripetal cutting force into unidirectional downward cutting. The tension is displayed by a scale groove to achieve continuous traction.
It reduces the probability of postoperative keyhole anal deformity, promotes wound healing, and allows patients to wear it continuously without affecting daily life and defecation. The traction force can be controlled by scales, avoiding the pain of traditional surgical adjustments.
