An instrument for use in minimally-invasive procedures generally including a pair of coaxially arranged shafts, an end-effector at the distal ends of the shafts, and an actuator at the proximal ends of the shafts. The end-effector is in the form of a suture holder which includes a first, fixed arm at a distal end of a first, fixed outer shaft, and a second, movable arm at a distal end of a second, movable inner shaft. The fixed arm includes a u-shaped end, which defines an opening adapted to receive a portion of an elongate flexible suture material. A closure pin fixed at an end of the movable arm moves back and forth, opening and closing the opening in the u-shaped end of the fixed arm. The closure pin extends from the movable arm into a pin guide opening through one leg of the u-shaped end of the fixed arm. |
