Abstract:
1. A hemostatic pedicle punch for establishing a hole in a vertebra pedicle when deployed thereon during pedicle screw insertion processes, said hemostatic punch comprising: a shaft, said shaft having a length formed by a proximal end and a distal end; said shaft flaring outwardly between said proximal end and said distal end to form an annular lip at said distal end; a truncated spike, said truncated spike projecting from said distal end of said shaft; said hemostatic pedicle punch being formed of a radiation translucent material except for a radiation opaque center core, said radiation opaque center core running longitudinally along at least part of said length of said pedicle punch, beginning from said proximal end an orifice running through said hemostatic pedicle punch, said orifice beginning at said proximal end of said shaft and running through said central core to said truncated spike; two or more mini-protrusions protruding from said distal end and terminating in a sharp point, said two or more mini-protrusions working in combination with said lip to stabilize said pedicle punch to provide hemostatic penetration of said pedicle; and a cannula, said cannula comprising a plastic tube, said tube having an inner surface and an outer surface, and first and second ends adapted to receive and transport a pedicle probe; said cannula being disposed in said orifice of said pedicle punch until said second end contacts said truncated spike; said cannula second end comprising a truncated conical shape for punching through said pedicle.
