Ferris-Smith-Kerrison Punch down 5mm, 18cm

Clinical Application

This down-biting Kerrison punch is engineered for controlled resection of small amounts of bone and ligament in confined operative corridors. The 5 mm bite size provides measured, focal removal during laminectomy, foraminotomy, microdiscectomy and comparable neurosurgical and ENT procedures. The down-oriented jaw is particularly useful when working on the inferior aspect of a lamina or when a downward bite improves visualization and access in tight spaces.

Design & Configuration

The punch-down geometry places the cutting edge on the inferior-facing surface of the jaw, allowing the surgeon to approach bone or ligament from above while delivering a predictable, forward-to-downward bite. The 18 cm overall length balances in-field reach with tactile feedback, permitting access into posterior cervical, thoracic and lumbar corridors without excessive shaft flex. A 5 mm distal bite size supports precise, incremental bone removal to minimize collateral disruption of adjacent neural tissue.
