1. A spinal disc preparation tool, comprising:
an elongate shaft having an inner lumen extending therethrough along a longitudinal axis between proximal and distal ends thereof; a lower jaw located on a distal end of the elongate shaft for receiving tissue and delivering tissue to the inner lumen; an upper jaw pivotally movable relative to the lower jaw; and a handle coupled to a proximal end of the elongate shaft, the handle having formed therein an aspiration hole in fluid communication with the inner lumen; wherein the aspiration hole is positioned such that the aspiration hole is blocked by a portion of a monolithic actuator handle when the actuator handle is actuated, the actuator handle being pivotally coupled to an actuator shaft coupled to the upper jaw for pivoting the upper jaw relative to the lower jaw; and wherein the upper jaw includes one or more holes formed in a top surface thereof and the lower jaw includes one or more holes formed in a bottom surface thereof, the holes in the upper and lower jaws allowing gas to pass therethrough to aid in aspiration of cut tissue through the inner lumen.
