Surgical instrument for tying a knot in a length of suture at a remote location
First Claim
1. A method of tying a surgical knot in a length of suture at a remote surgery location using a surgical instrument comprising a rod having opposite first and second ends with a slot formed in the first end, and a length of suture with opposite first and second ends wrapped in a plurality of loops around the first end of the rod, the second end of the suture extending to adjacent the second end of the rod and the first end of the suture having a needle secured thereto, the method comprising the steps of:
- positioning the rod first end and the needle proximate to the surgery location by manual manipulation of the second end of the rod;
passing the needle and the attached first end of the suture through the surgery location and thereby forming a stitch through the location;
passing the needle and the attached first end of the suture into the slot in the rod first end and beneath a first loop of suture on the rod;
pulling the needle and the attached first end of the suture out of the slot and away from the rod first end, thereby causing the first loop to be pulled off the rod first end and forming a first throw of a knot in the suture at the stitch;
passing the needle and the attached first end of the suture into the slot in the rod first end and beneath a second loop of suture on the rod; and
pulling the needle and the attached first end of the suture out of the slot and away from the rod first end, thereby causing the second loop to be pulled off the rod first end and forming a second throw of a know in the suture at the stitch.

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 slot at one end and a length of suture wrapped over the rod and slot 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 to form a throw of a knot in the suture.

5. 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 slot formed in the first end of the rod; 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 and over the slot formed in the first end of the rod, the loop is formed, in the suture by the suture extending longitudinally along the rod from the rod second end toward the rod first end to a first bend formed in the suture intermediate the rod first and second ends and adjacent the slot, the suture next extending laterally relative to the rod from the first bend and wrapping laterally at least one complete revolution around the exterior surface of the rod and over the slot to a second bend formed in the suture engaging around the first bend, and then the suture extending longitudinally relative to the rod from the second bend toward the rod first end and to the needle secured to the suture first end with a sufficient length of the suture provided between the second bend and the needle enabling the needle to pass through a tissue to be ligated and then through the loop formed in the suture thereby tying a knot in the suture. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)

15. 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 having at least one loop formed therein, the loop is formed in the suture by the suture extending longitudinally along the rod from the rod second end toward the rod first end to a first bend formed in the suture intermediate the rod first and second ends, the suture next extending laterally relative to the rod from the first bend and wrapping laterally at least one complete revolution around the exterior surface of the rod to a second bend formed in the suture engaging around the first bend, and then the suture extending longitudinally relative to the rod from the second bend toward the rod first end and to the needle secure to the suture first end with a sufficient length of the suture provided between the second bend and the needle enabling the needle to pass through a tissue to be ligated and then through the loop formed in the suture thereby tying a knot in the suture; and means provided on the rod for enabling the needle to be passed beneath the loop wrapped around the rod pulling the first end of the suture beneath the loop. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
