  • Patent number: 5971447
    Abstract: A hand held knot tying device used for tying fishermen's knots, such as nail knots, which are used to tie monofilament segments to fishing line segments. The device has a straight portion that extends approximately one-half of its length at which point the other half tapers down to a diameter that is small relative to the straight portion. The grooves run the length of the straight portion but run out in the tapered portion due to the taper going below the depth of the grooves. To tie a knot with the device, the fisherman lays the fishing line in the widest groove, then, coming from the opposite direction, he lays the monofilament in one of the other grooves. Next, and having provided enough slack to do so, he wraps the monofilament back upon itself and the fly line, so as to form multiple coils, and then tunnels the free end of the monofilament back beneath the coils, using the third groove as a tunneling means. He then tightens the coils to form a knot around the straight portion.

  • Patent number: 5728109
    Abstract: An improved method of forming a non-slip surgical knot for fastening tissue, and the knot prepared by the improved method, are disclosed. A partially tied knot which has a first loop and knot loops formed about the first loop to create a common loop core receiving the first loop is initially provided. The distal end of the suture filament from which the partially tied knot is made is passed through the tissue, and it is then fed through the first loop to form a tissue-fastening loop. The improvement involves pulling the first loop and a portion of the suture filament through the common loop core, thus eliminating the first loop and forming a distal loop positioned adjacent the common loop core. When this improved method is used to form the non-slip knot, a knot with a consistently high knot security can be formed without the need to provide a tension on the suture filament which exceeds the breaking strength of the suture.

  • Patent number: 5562684
    Abstract: A surgical knot pusher device comprises a thick-walled cannula or tube having a beveled elliptical face and a central channel for slidably receiving one end of a suture. The other end of the suture is slidably inserted in one of a pair of longitudinal grooves formed on the outer surface of the cannula which intersect the elliptical face at the opposite ends of its major axis. One of the longitudinal grooves extends along the longest portion of the cannula and the other longitudinal groove extends along the shortest portion of the of the cannula. As the knot pusher device is inserted into a surgical port, a knot formed in the suture is engaged by the beveled face and advanced toward a surgical site. A notch is formed at the proximal end of the cannula for receiving the end of the suture threaded into the central channel. A threading element comprising an elongated rod with a deformable loop is provided to thread the suture into the central channel of the cannula.

  • Patent number: 5536273
    Abstract: A suture applier instrument for tying suture and loop ligatures in laparoscopic excisional procedures such as LAVH, tubal ligation, salpingectomy, cophorectomy and appendectomy; in the repair of the fallopian tubes, uterus and ovaries; and in retropubic colposuspension using locking slip knots; and an efficient extracorporeal method to effectively lock them. The slip knot is held at the tip of the suture applier instrument and is kept in position on the target tissues while its two suture strands are operated extracorporeally, tying the loop ligature with one of the strands and locking or tightening the knot itself with the other. Additional hitch knots may be introduced and tied after the slip knot has been applied, using the same instrument. New knots, spool for pretied knot sutures and knot tying techniques for use with the suture applier are presented.

  • Patent number: 5536051
    Abstract: A knotting tool includes an elongate handle with a cord support projecting from the handle. The cord support includes walls about which the cord being knotted is wound. A guideway along the cord support receives cord segments with one of the segments being inserted through multiple windings formed on the cord support. A cord lock is insertable through an aperture in the cord support to temporarily bind a cord segment in place and may be in the form of a paper clip. A notched end of the cord support retains a reversed cord segment in place during knot formation. A deflector in the guideway acts on an inserted end of a cord segment to divert same out of the guideway to facilitate grasping. A method of forming a knot is disclosed using the present tool.

  • Patent number: 5454821
    Abstract: A system for the application of knots in surgical suture material consists of a pre-knotted surgical suture means (1) and a surgical knot applicator. The pre-knotted surgical suture means (1) has a sleeve (10) open at both ends (12, 13) and a surgical suture material (15) such as thread, cord, etc., which suture material is tied around the sleeve (10) to produce a pre-knotted displaceable knot (18) and has a free end (16). The surgical knot applicator contains a shaft, whose distal end-zone comprises an opening corresponding to the diameter of the sleeve (10). The sleeve (10) inserted with its proximal zone (12) into this opening is pulled back into the interior space of the shaft with a pulling-in device. The suture and the knot (18) are pulled tight by moving the free end (16) of the surgical suture material (15) guided through the sleeve (10) in proximal direction (arrow) with a pulling device.

  • Patent number: 5447512
    Abstract: A controller for an intracorporeal knot tying device including a hollow handle housing and a slider operator captured in the handle for linear motion between proximal and distal positions. The slider attaches to an elongated, tubular member formed of a shape memory material for carrying a suture thread through an internal passage and a bight formed in the tube. An outer sheath extends from the handle and supports the remaining length of the tube. When a knot is to be formed, a free end of the suture is pulled through tubular member by means of an introducer. A physician advances the operator to displace the distal end of the tubular member to form the bight. Subsequently, the physician retracts the operator to a proximal position to straighten the bight and throw off a knot in the suture thread for subsequent tightening. The operator includes means for grasping the suture.
