Spinal surgery punches designed to excise small segments of tissue (typically in the form of a thin disc several millimeters in diameter) from the posterior arch of a vertebra (i.e., laminectomy). These punches are typically handheld, manual instruments with a cutting mechanism (e.g., movable, two-part) at the distal end with a size appropriate to perform the procedure and are operated by grasping an articulated handle. Laminectomy punches are available with working ends designed for straight, downward, or upward cutting.
