Ferris Smith Kerrison punch 3x5mm up ward

Clinical Application

This up‑biting Kerrison punch is intended for precise resection of small bone and ligamentous tissue during spinal and neurosurgical decompression procedures (for example laminotomy/laminectomy and foraminotomy). The upward‑directed bite is useful when working on the superior aspect of a lamina or when approaching a lesion from below, permitting controlled removal of bone while preserving adjacent dura and neural elements. The 3 x 5 mm bite size supports incremental bone removal in confined working corridors.

Design & Configuration

An up‑biting Kerrison geometry orients the cutting jaw to bite toward the surgeon when the instrument shaft is directed away from the surgeon. This configuration improves visibility of the cutting plane and facilitates small, controlled bites in narrow posterior spinal corridors. The Ferris‑Smith variant is a recognized pattern for robust bite mechanics in neurosurgical and spine settings; the smaller 3 x 5 mm window favors stepwise resection over large bulk removal, reducing the risk of over‑resection in delicate anatomy.
