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 1):
An instrument for tying a knot in a suture laparoscopically, involving passing the head end of a suture from a donor grasper to an adjacent recipient grasper behind and around the tail end of the same said suture, comprising:\n the shafts of two small diameter laparoscopic graspers housed within a common external sheath, with one being a regular grasper having a customary scissors type of handle, and acting as a recipient grasper; and a second grasper without a handle but rotatable, and acting as a donor grasper, and further comprising: having a narrow gap between the tips of the said two graspers for trapping the tail strand of the said suture; the said donor grasper having a non-movable inner/lower jaw enabling its rotation; the said recipient grasper having both a straight lower jaw and a single acting 90 degree movable upper jaw providing a platform for reception of the passing suture; having the jaws of the said donor grasper in the vertical plane in the resting state and able to rotate through 90 degrees after grasping the head end of the suture in it's jaws; having a compression spring holding closed the upper jaw of the said donor grasper; and having a compression spring holding open to 90 degrees the upper jaw of the said recipient grasper.
