Ferris-Smith-Kerrison Punch up 5mm 18cm 40

Clinical Application

This up-biting Kerrison rongeur is designed for controlled, incremental removal of cortical and cancellous bone and ligamentous tissue in confined surgical corridors. Its 5 mm bite size enables precise nibbling during posterior spinal decompression (laminotomy, laminectomy, discectomy) and cranial or otolaryngology procedures where small, accurate bone bites near neural elements are required. The up-biting tip orientation allows the surgeon to elevate and resect bone toward the operative field while minimizing downward force on the dura.

Design & Configuration

An up-biting geometry places the working jaw to remove bone toward the instrument shaft, improving visibility and control when working beneath lamina or around the thecal sac. The Ferris-Smith-Kerrison pattern combines a strong jaw profile with a shaft length that balances reach and tactile feedback; the 18 cm length is suited for standard posterior approaches where access depth and hand clearance are factors. The 5 mm bite promotes staged bone removal for fine control and reduced risk of inadvertent large defects.
