Brief Patent Description - Full Patent Description - Patent Application Claims
FIELD OF THE INVENTION [0001] The invention relates to methods and devices and more specifically relates to the arthroscopic fixation of tissue to bone using sutures. BACKGROUND OF THE INVENTION [0002] Invasive and open surgery methods of attachment of tissue to bone to repair tissue is known and used. An example of this method is rotator cuff surgery. In some processes, foreign objects, such as suture anchors, staples or screws, are implanted and used to connect tissue to bone. SUMMARY OF THE INVENTION [0003] The present invention overcomes the invasive nature of tissue repairs by open surgical processes, and reduces the reliance on implants associated with arthroscopic repairs. The invention uses the bone constructs of the patient to attach sutures to torn or dysfunctional tissue. Suture is passed through intersecting tunnels formed in the bone. An end of the suture extends from each of the tunnels, and the ends are used to secure the tissue to the bone, such as by arthroscopic tying of the ends, and pulling the tissue against the bone. DESCRIPTION OF THE DRAWINGS [0004] FIG. 1 illustrates a rotator cuff drill guide in place with a trephine piercing a torn rotator cuff. A single stand of suture is shown passing through the drill guide, rotator cuff tissue, into and out of the humeral head, and exiting the central lumen of the trephine. [0005] FIG. 2 illustrates three arthroscopic simple stitches, a repaired rotator cuff, and two lateral vertical portals. [0006] FIG. 3 illustrates two arthroscopic mattress stitches where the initial suture in the center bone tunnel was used to pass two sutures. [0007] FIG. 4A is the drill guide assembly having an arcuate drill guide, a straight drill guide and a handle. [0008] FIG. 4B is the stylus for the arcuate drill guide lumen. [0009] FIG. 4C is the trephine guide pin that will fit into the straight drill guide lumen with enough clearance for the trephine. [0010] FIG. 4D is the arthroscopic trephine. [0011] FIG. 4E is an offset hook probe that will pass into the trephine. [0012] FIG. 4F is a suture stylus with suture loosely attached. [0013] FIG. 5 illustrates insertion of the arcuate lumen rotator cuff drill guide leading with the stylus. [0014] FIG. 6 illustrates the stylus that has been passed through the straight drill guide lumen. [0015] FIG. 7 illustrates the trephine inserted to a calibration point that advances the tip past the bone void left by the stylus. [0016] FIG. 8 illustrates the trephine partially retracted to a second calibration mark, the suture stylus with suture being advanced and the hook probe in a readied position. [0017] FIG. 9 illustrates the suture lodged in the bone void left by the stylus after being left behind by the suture stylus, and the hook probe which has been passed through the trephine to capture the suture. [0018] FIG. 10 demonstrates an embodiment of the device using straight, but non-parallel drill guides. [0019] FIG. 11 demonstrates an embodiment of the device showing an additional configuration of an arcuate drill guide.
