ELASTIC BAND LIGATION DEVICE WITH ANTI-PINCH FEATURE AND METHOD FOR TREATMENT OF HEMORRHOIDS |
摘要 |
An elastic band ligation device for treatment of hemorrhoids including an inner tubular member for retaining a stretched elastic band over the front end thereof, a plunger in the tubular member with a handle extending away from the front end of the inner tubular member, the handle for sliding the plunger away from the rear end of the inner tubular member to provide a suction for drawing hemorrhoidal tissue into the inner tubular member through the opening at the front end. An obturator is disposed within the inner tubular member having a rounded end, the end of the obturator and the inner surface of the inner tubular member defining an anti-pinch structure. An outer tubular pusher sleeve is configured to provide a limited friction fit over the inner tubular member, with an external end of the outer tubular pusher sleeve adjacent the stretched elastic band. |
