1. A surgical knot pusher and suture cutter apparatus, the apparatus comprising:
a handle;
an elongate holding tube attached to the handle, the elongate holding tube including a slot opening from a distal end of the holding tube and configured to allow a suture to pass therethrough;
an inner mandrel within the holding tube, the inner mandrel having a D-shaped cross-section forming a notch extending proximally from a distal end of the inner mandrel along a side region of the inner mandrel, the notch defining a suture receiving region, the notch being alignable with the slot such that the suture can pass through the slot into the suture receiving region, wherein the inner mandrel is rotatably movable relative to the holding tube, and wherein rotation of the inner mandrel moves the notch out of alignment with the slot such that the suture received in the suture receiving region can be captured between the inner mandrel and the holding tube; and
a tubular cutter around the holding tube, the tubular cutter configured to be axially movable relative to the holding tube to cut the suture when extended distally.
