Abstract
A surgical instrument facilitates tying of a knot in a length of suture material at a remote surgical location. The instrument is comprised of an inner rod having a length of suture wrapped over the rod in a particular pattern. A needle may be secured to a free end of the suture and the pattern of wrapping the suture on the rod enables loops of suture to move off the rod end and over the needle to form a knot in the suture. The inner rod is received in an interior bore of an outer rod for manually controlled reciprocating movement therein. The inner rod is manually retracted into the interior bore of the outer rod to cause the outer rod to move the loops of suture off the inner rod end and over the needle in forming a knot in the suture.
