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.

A ligator for pinching off hemorrhoids and similar body tissues at a body link portion thereof, 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 having a volume approximating the size of the hemorrhoid to be pinched off and facing outwardly and to one side, 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 link portion 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; the outer end of the actuator sleeve having fixed thereto a bifurcated support attached at its base end to the sleeve for reciprocable movement therewith, and with an inclined slot in each bifurcation, the slots capturing projections on the external periphery of the ejecting means slidably mounting the ejector on the support.
