ELASTIC BAND LIGATION DEVICE AND METHOD FOR TREATMENT OF HEMORRHOIDS

摘要

An elastic band ligation device for treatment of hemorrhoids and method of treating hemorrhoidal tissue are provided including a plastic inner tubular member for retaining a stretched elastic band over the front end thereof. The inner tubular member has an arcuate configuration extending along at least a portion of the length thereof for a sufficient distance for insertion into the rectum of a patient. A plunger is provided in the tubular member with a handle to allow the operator to pull the plunger and generate a suction for drawing hemorrhoidal tissue into the inner tubular member through the opening at the front end. A plastic outer tubular pusher sleeve is provided having an arcuate configuration corresponding to the arcuate configuration of the inner tubular member to provide a limited friction fit over the inner tubular member. The pusher sleeve is provided with a thumb pusher for the operator to push the outer tubular pusher sleeve towards the front end of the inner tubular member and release the elastic band from the front end of the inner tubular member to engage hemorrhoidal tissue extending through the opening in the inner tubular member. The invention also provides a method of treating hemorrhoidal tissue and an elastic band fabricated from a non-latex material.
