Abstract: The invention relates to a surgical instrument for ligation of internal tissues, such as hemorrhoids, in a cavity of the body by means of an elastic cord. The instrument comprises an inner front-cylinder (1) with the elastic cord (2) strained around its front end and a displaceable outer discharge-cylinder (3) arranged on the front-cylinder (1). At displacement the elastic cord (2) is pushed beyond the front-cylinder (1) and ligates the stem of a tissue (12) inserted in the front-cylinder (1). One of the two cylinders (1;3) is connected to a profiled tube (4) and the other cylinder (3;1) is connected to one end of a relatively stiff strip (5), which constitutes the actuating means (6) for the relative displacement of the cylinders. The strip is preferably formed into an actuating loop and the displacement is attained by pressing the actuating loop (6) towards the tube (4).

Abstract: The present invention is a medical device for inverting diverticulum and closing such diverticulum in the inverted position. The apparatus includes a reciprocating vacuum tube for inverting the diverticulum and a caliper for placing a fastening device such as an elastic band around the base of the diverticulum.

Abstract: An elastic ligature applicator device including a central member for storing a plurality of unexpanded elastic ligatures in series fashion, a conical expander and a ligature dilator for pushing a ligature over the expander and onto grasped anatomical tissue. An optional applicator manipulation facilitating assembly may be provided to ease use of the applicator device during a surgical procedure. Components are readily disassembled to load a series of unexpanded elastic ligatures onto the applicator device.

Abstract: Device for applying elastic ligatures to an orthodontic bracket, which includes jaw elements spreadable for stretching an elastic ligature and for dispensing the ligature directly onto an orthodontic bracket in an orthodontic system so as to attach an archwire to a bracket. The device may be in the form of a gun which can be used first to load a ligature from a dispenser and then to unload the ligature around and onto a bracket.
