Clinical Application
This up-biting Kerrison is designed for controlled removal of small bone and ligamentous tissue during spinal and cranial procedures. The upward-directed bite is especially useful in posterior decompression procedures—laminotomy, foraminotomy and focal bone resection—where working beneath an overhanging edge or superior lamina requires a superiorly directed cutting action. The 6 mm bite allows incremental, precise tissue removal to minimize collateral soft-tissue trauma and help preserve bony landmarks.
Design & Configuration
The Ferris-Smith up-biting geometry positions the jaw so that each squeeze produces a superior-directed bite, which improves access beneath ledges and undercuts commonly encountered in posterior spinal corridors. At 18 cm overall length, the instrument balances reach into deeper operative fields with tactile control at the handle, supporting precise, single-handed control for serial bites. The 6 mm bite size provides a predictable working volume per bite, facilitating controlled bone removal in narrow exposures.
