Ferris Smith Kerrison Punch up 4mm 18cm 40

Clinical Application

This up‑biting Ferris‑Smith Kerrison punch is designed for controlled en bloc removal of bone, lamina, ligamentum flavum and small soft‑tissue fragments during decompression procedures. It is commonly used in lumbar and cervical laminotomy/laminectomy, foraminotomy and other spinal and neurosurgical exposures where a superior‑directed bite is advantageous. The 4 mm bite size provides a balance between tissue capture and precision for work in confined spinal canal and foraminal spaces.

Design & Configuration

The up‑bite orientation directs the cutting surface toward the instrument’s dorsal side, allowing the surgeon to take bites from inferior to superior or to remove bone lying above the working channel without repositioning the instrument tip. The 18 cm shaft length gives reach into deep operative corridors while maintaining tactile feedback at the jaw. A moderate 4 mm bite diameter supports incremental, controlled bone resection to minimize risk to adjacent neural structures.
