Abstract:
This instrument is intended to facilitate intra-corporeal laparoscopic tying of knots. The shafts of two small diameter laparoscopic graspers are combined within a common external sheath, and both are joined to a common handle, to be used by one hand. One grasper has no handle, but is able to rotate, and acts as a donor grasper, whilst the other has a regular scissors type of handle, is stationary, and acts as a recipient grasper. The instrument enables the head end of a suture to be passed from a donor grasper to an adjacent recipient grasper, passing behind and around its tail strand, forming the knot, in the same manner as the tying of shoe-laces.

Claim (Index 2):
A method of tying a knot in a free length of suture laparoscopically with the instrument of  claim 1 , wherein the head end of a suture is passed behind and around its tail strand from a donor grasper to an adjacent recipient grasper thus encircling the said tail strand forming a knot, and comprising the steps of:\n (1) grasping the head end of a suture with the jaws of the said donor grasper and pulling it back over the said tail strand; (2) advancing the said instrument forwards to trap the said tail strand in the slot between the tips of the two said graspers, with the said donor grasper under the said tail strand; (3) rotating the said donor grasper and its jaws 90 degrees clockwise, thus placing the head end of the said suture on top of the straight lower jaw of the said recipient grasper; (4) closing down the upper jaw of the said recipient grasper, taking over the said head end of the said suture, and pulling away forming the knot.
