A hand instrument for retrieving suture and advancing a suture knot within a patient. The instrument has a shaft with proximal and distal ends. A hinged jaw in the form of a crabclaw disposed on the distal end of the shaft captures suture within a closed aperture formed by the jaws or is used to pinch the suture between the jaws. A hand mechanism disposed on the proximal end of the shaft opens and closes the jaw.
