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 rigid 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).
