Abstract: An anoscope for use with a medical instrument insertable within the interior of the anoscope. The anoscope comprises a tubular member having a longitudinal axis with a proximal end and a distal end. The distal end is insertable into the rectum of a patient while the proximal end remains outside the body. A first longitudinal slot extends from the distal end toward the proximal end, and a second longitudinal slot extends from the proximal end toward the distal end. The first and second longitudinal slots are separated by about 180° on the surface of the tubular member. The first longitudinal slot is adapted to permit access to a site to be treated within the rectum and the second longitudinal slot is adapted to accommodate pivoting of the medical instrument at an angle to the longitudinal axis of the tubular member to improve access to the site to be treated.

Abstract: An elastic band ligation device for treatment of hemorrhoids permits a doctor to band hemorrhoidal tissue without an assistant and does not have to be attached to an aspirator. The device has the capability of suctioning tissue into a tubular member before banding. A plastic inner tubular member retains a stretched elastic band over a front end of an inner tubular member which extends for a sufficient length for insertion into the rectum of a patient. A plunger in the tubular member may be slid backwards to draw a suction in the tubular member to draw tissue in through the front end. A plastic outer pusher sleeve fits over the tubular member and is adapted to push the elastic band off the front end of the tubular member to capture the hemorrhoidal tissue drawn into the tubular member.
