Ferris Smith Kerrison Punch up 1mm, 18cm

Clinical Application

This up-biting Kerrison punch is configured for precise removal of small bone and ligament fragments in confined spinal and cranial surgical corridors. The 1 mm bite size enables incremental tissue resection during posterior decompression procedures such as laminectomy, laminotomy, foraminotomy and microdiscectomy, as well as delicate bone work in select neurosurgical exposures where controlled, minimal bites reduce the risk of excess bone removal.

Design & Configuration

An upward-oriented cutting tip allows the surgeon to approach tissue from inferior to superior angles and to work beneath overlying structures without excessive shaft-to-line-of-sight interference. The 18 cm overall length provides reach into deeper operative fields while preserving tactile feedback. Finger-ring handles give controlled, reproducible bites and facilitate fine adjustments in bite depth and orientation—important when operating near neural elements.
