Abstract
A method and a tool for tying a stitch knot. The tool comprises a first elongated member and a grasping member. The first elongated member includes a helix on one end. The helix has a filament extending from the first end, and a threading device is attached to the free end of the filament. The grasping member is separate and apart from the first elongated member, and includes an elongated shaft. A grasper is mounted on the first end of the shaft, and a portion of the shaft near the grasper is sized to reside within the helix for axial movement therewith. The method for tying the stitch knot involves positioning the shaft within the helix. The grasper is used to insert the threading device and pull the free end of the filament through an area to be stitched, and then to grasp the free end of the filament near the threading device. The grasping member is removed from the inner space of the helix, thus drawing the free end of the filament through the helix. When the grasping member and helix are moved apart from each other and the filament is removed from the helix, a loop for the stitch knot is formed. Moving the grasping member and helix further apart tightens the loop to the area to be stitched.
