摘要：
A suture manipulating instrument for passing and retrieving suture through a tissue includes a handle mechanism, an elongate shaft extending from the handle, and a working distal end. The working distal end includes a needle body, a lumen defined by the needle body, a tissue penetrating distal tip, and a lateral slot. A preformed inner member is movably disposed within the lumen of the needle. The handle mechanism is used to extend the wire from the lateral slot of the needle, and to retract the wire into the lateral slot, allowing the working end of the instrument to grasp and manipulate suture by pinning and/or trapping the suture against the needle. In embodiments the inner member is further retracted within the needle lumen, drawing a length of suture into the needle lumen. The suture is subsequently ejected from the needle lumen to form a suture loop.
