1. A surgical instrument for tying a knot in a length of suture, the instrument comprising:
- a rod having a longitudinal length with opposite first and second ends and an exterior surface extending between the first and second ends;
a length of suture having opposite first and second ends, the first end of the suture being secured to a needle and the second end of the suture being positioned adjacent the second end of the rod, the length of suture extending from its second to its first end along the rod from the rod second end to the rod first end with at least one loop being formed in the suture and wrapped laterally around the exterior surface of the rod;
a plurality of loops are formed in the suture and are each wrapped laterally around the exterior surface of the rod; and
,the plurality of loops are formed in the suture by the length of suture extending longitudinally along the rod from the rod second end toward the rod first end with a first bend being formed in the suture and the suture extending laterally from the first bend making at least one revolution around the exterior surface of the rod back to the first bend, a second bend being formed in the suture around the first bend and the suture extending longitudinally from the second bend toward the rod first end.

Abstract
A surgical instrument and its method of use facilitate tying of a knot in a length of suture material at a remote surgical location. The instrument is comprised of a rod having a length of suture wrapped over the rod in a particular pattern. A needle is 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 and suture to form a knot in the suture.

9. A surgical instrument for tying a knot in a length of suture, the instrument comprising:
-
a rod having a longitudinal length with opposite first and second ends and a exterior surface extending between the first and second ends; a length of suture having opposite first and second ends, the first end of the suture being secured to a needle and the second end of the suture being positioned adjacent the second end of the rod, the length of suture having at least one loop formed therein, the loop being wrapped at least one revolution around the exterior surface of the rod; means provided on the rod for enabling the needle to be passed through the loop wrapped around the rod pulling the first end of the suture through the loop; a plurality of loops are formed in the suture and wrapped around the exterior surface of the rod; and
,the plurality of loops are formed in the suture by the length of suture extending longitudinally along the rod from the rod second end toward the rod first end, a first bend being formed in the suture adjacent the rod first end, the suture from the first bend being wrapped laterally around the exterior surface of the rod, then a second bend is formed in the suture around the first bend and the suture extends longitudinally toward the rod first end from the second bend. - View Dependent Claims (10, 11, 12, 13, 14)
