ABSTRACT:
An instrument for surgical suturing includes a shaft, and a needle disposed slidably for longitudinal travel with respect to the shaft. A prong formed on one end of the shaft projects across a longitudinal axis of the needle and has an opening formed through the prong that provides a clearance through which a tip portion of the needle passes when it is advanced. Slots formed on a surface of the prong facing the shaft releasably hold suture across the opening. The suture is held in the slots by passing the suture strands separately back around the sides of the prong, then together up through a channel formed on the prong above the slots, and securing the strands in a pinch slot formed in a handle of the instrument. Advancing the needle through the clearance allows a hook formed on the tip of the needle to capture the suture. Once withdrawn, the needle draws the suture back through tissue pierced during advancement. The suture is released from the slots and drawn back through the tissue for further knot tying and suturing to effect the tissue repairs.
