There are many methods of tying a knot in a surgical suture. One method is to form a loop in the suture and then pull the other end of the suture through the loop. To do this laparoscopically is the object of the present invention. The finger loop handles of two small diameter laparoscopic graspers are sacrificed, and their shafts are then placed within a single common sheath, using also a single common in-line handle. The jaws of the graspers are operated by spring loaded push knobs on the handle. A loop is formed by grasping the same suture at two points a short distance apart simultaneously with the two graspers, and then bringing them together. The present invention is capable of doing this by virtue of one of the two graspers being slide-able, extendable and retractable.
