Ferris Smith Kerrison punch down 5x5mm 18cm

Clinical Application

This down-biting Kerrison punch is designed for controlled resection of small bone and ligamentous tissue during spinal and neurosurgical decompression procedures, including laminectomy, foraminotomy, and limited laminotomies. The 5 x 5 mm bite size offers predictable, incremental bone removal suitable for work around neural elements and within narrow operative corridors. The 18 cm overall length provides reach for standard posterior approaches and tubular retractor systems without sacrificing tactile control.

Design & Configuration

The Ferris-Smith down-biting configuration orients the cutting tip toward the shaft axis, which facilitates working on the ventral aspect of posterior elements or under the lamina while minimizing instrument interference. A box-lock hinge with single-action punch mechanics delivers a firm, controlled bite and consistent jaw alignment. The 5 x 5 mm jaw geometry balances removal volume per bite with precision, helping surgeons avoid excessive bone take while maintaining efficient progress. The shaft length provides access to deeper exposures common in lumbar and thoracic cases.
