Abstract
A surgical knot tier instrument (10) for use in conjunction with a needle (29) connected to suture thread (13) and a pair of surgical forceps (31), for placing a knot (11) in a wound (15) in body tissue (17), is described. The knot tier instrument is comprised of an elongate rod member (19) having a relatively small circular cross-section along a longitudinal axis A--A of the rod. This allows the rod to be introduced into a body cavity through an entry puncture wound for helping a physician or surgeon to close the wound in the body tissue without having to completely open up the body cavity. A proximal, working end (21) of the rod is provided with a notch (25), formed diametrically across an end face (23) of the rod, and a slot (27), which is provided diametrically across the face, offset 90.degree. from the notch. During the surgery procedure, the forceps are used to manipulate the needle connected to the suture thread to pull the needle with the suture thread through the wound. The slot in the rod which is magnetized then acts to receive and hold the needle to free up the forceps. The forceps can now be manipulated to regrasp the needle to form the knot in the suture thread. The notch is then mounted on the knot with the opposed ends of the suture thread extending from the opposed ends of the notch. The notch is used in conjunction with the forceps to tighten and center the suture on the wound. That way, the suture knot helps to draw the tissue on either side of the wound together in a uniform manner.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
