Anchor/Suture Used for Medical Procedures

摘要

For suture tying in a medical procedure including the use of an anchor that includes a suture locking device that includes a sliding pin guided by axial side slots formed in the locking device that forces the suture where the two ends thereof are inserted into the interior of the suture locking mechanism to drive the captured suture and pin to fit into a recess on the top of the suture locking mechanism such that the top of the pin binds the suture against the upper inner surface of the recess. The recess can be serrated to enhance the locking capability and the pin is polygonal shaped to provide side surfaces that run parallel to the wall of the recess to assure that the side portion of the pin does not fracture the suture and cause it to weaken. The locking of the suture is automatic upon the deployment of the anchor which actuates the pin into the locking position, thus eliminating the necessity of manually knotting the suture and improving the cinching of the tissue to the bone. The suture locking mechanism is usable for attaching tissue to the bone, tying tissue to tissue and the like. The disclosure also includes the method of deploying the combined anchor and suture locking device in a medical procedure.

主权项

1. A suture locking device for securing and locking the ends of suture,
said suture locking device having a cylindrical shaped body having a wall defining a cavity, a top portion and a side portion, a pin laterally disposed in said cavity, said wall defining a recess formed in said body adjacent to the top portion and being in axial alignment with said pin, openings formed in said side wall portion in said suture locking device for accepting reaches of said suture intended to be tied so as to extend said suture intended to be tied laterally in said cavity to lie between said pin and said recess wall, said suture reaches in said cavity being urged against said recess wall and said pin upon deployment of said suture locking device whereby said suture is locked in place owing to the squeezing force exerted on said suture reaches by said pin against said recess wall.
