Abstract
A surgical instrument for ligating internal tissue of a cavity in the human body by means of an elastic cord is disclosed. The instrument comprises an inner tube, having a distal and a proximal part, with the distal part having a distal end adapted to carry an elastic cord strained around it and with the proximal part arranged to be connected to a vacuum source, wherein at least one tube bend is formed between the distal and proximal part. Further, an outer discharge member is provided to push said elastic cord beyond the distal end of said tube to close around the stem of a tissue when inserted in the tube, the discharge member comprising an outer discharge part displaceably arranged around the distal part, an actuating part displaceably arranged around the proximal part, and a flexible connection part following said tube bend and arranged to transfer a movement of the actuating part to the discharge part.
