This is a laparoscopic instrument for facilitating intra-corporeal tying of knots. The shafts of two small diameter laparoscopic graspers are combined within a common external sheath. One grasper has a regular scissors handle, is stationary, and acts as a recipient grasper, while the other has no handle, but is rotatable and slidable, and acts as a donor grasper. It enables the head end of a suture to be actively passed from the jaws of the donor grasper to the jaws of the adjacent recipient grasper, after passing behind and around the tail strand, thus forming a knot. The current version of this instrument introduces two additional features, one being the passive production of the rotation by the straight sliding mechanism, the other being the use of free-wheeling levers allowing rotation of the shaft of the donor grasper, without rotating the attached levers in the slots.
