A suture passing device includes a grasping mechanism and cannula having a sharp edge on a distal end. The grasper mechanism includes a hollow shaft slidably disposed within the cannula, with a first jaw fixedly secured thereto, and a second jaw pivotally coupled thereto, to pivot between a closed position wherein the second jaw engages the first jaw, and an open position. The slidable shaft permits the jaws to occupy a retracted position within the cannula, and an extended position. A plunger is slidably disposed within the hollow shaft, and pivotally coupled to the second jaw. A first handle is secured to the shaft, while a second handle is secured to the plunger, for jaw engagement/disengagement. The device also include means for locking sliding travel of the shaft relative to the cannula, after a full cycle of the slidable travel of the jaws between the extended and retracted positions has occurred.
