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.

Elastic band ligation device with anti-pinch feature and method for treatment of hemorrhoids

Elastic band ligation device for treating hemorrhoidal tissue, including an inner tube for retaining an elastic band, a plunger in the inner tube for drawing hemorrhoidal tissue into the inner tube, and an outer tube pusher sleeve disposed over the inner tube. A thumb pusher on the sleeve allows the operator to push the sleeve towards the front of the inner tube to deploy the elastic band from the front end of the inner tube onto hemorrhoidal tissue drawn into the inner tube. The sleeve has a locking mechanism including a tab for locking the sleeve to the inner tube to prevent relative movement of the sleeve and inner tube until the sleeve is unlocked by the user, thereby preventing premature deployment of an elastic band.

Elastic band ligation device with locking mechanism and method for treatment of hemorrhoids

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 inner tubular member with a handle for sliding the plunger to generate a suction for drawing hemorrhoidal tissue into the inner tubular member. An obturator connected to the plunger is provided within the inner tubular member. An outer tubular pusher sleeve with a limited friction fit is provided over the inner tubular member, the end of outer tubular pusher sleeve being adjacent the stretched elastic band. The outer pusher sleeve has a thumb pusher to allow the operator to push the outer pusher sleeve towards the front end of the inner tubular member or to secure the outer pusher sleeve and withdraw the inner tubular member, which deploys the elastic band on the hemorrhoidal tissue.
