1. A pedicle punch for establishing pilot holes in vertebra pedicles when deployed thereon during pedicle screw insertion processes, said punch comprising:

  • a proximal end and a distal end;

    a shaft distally projecting from generally about said proximal end and terminating in a truncated conical spike at said distal end;

    a lip outwardly projecting from and fixedly connected to said shaft, adjacent to said sharp conical spike and concentric thereto;

    a radiation opaque center core running longitudinally along the entire length of the pedicle punch, from said proximal end, through said shaft and lip outwardly projecting therefrom, to the very tip of said distal end;

    said radiation opaque center core having an orifice extending through said core from said proximal end to said truncated conical spike and;

    a radiation translucent outer layer concentrically surrounding and encasing said radiation opaque center core, running along the entire length of the pedicle punch but stopping short a short distance from the very tip of said distal end to allow said radiation opaque center core to extend sufficiently beyond the distal edge of said radiation translucent outer layer and form the bottom of said truncated conical spike of said shaft.
