ABSTRACT:
A ligator is provided for pinching off hemorrhoids and similar body tissues, comprising, in combination, a tubular housing; a suction tube fixedly mounted on the housing; and an actuator sleeve slidably mounted for reciprocable movement within the housing along the suction tube; a suction cup defining an open suction cavity facing outwardly and fixedly attached to and in flow communication with the suction tube for sucking a hemorrhoid into the suction cavity, the suction cup having means for receiving an elastic ring about the periphery of the open suction cavity; and means for ejecting said ring from the cup and onto the body portion link of a hemorrhoid sucked into the suction cavity and projecting from the cavity; said ejecting means being movable by reciprocation of the actuator tube between nonactuated passive and actuated ring-ejecting positions.
