undefined Ceramic Cut Micro Kerrison Detachable Rongeurs feature a swing style shaft which opens up to allow easy cleaning of the shaft interior. Once the thumb release lever above the handle is depressed, the top portion of the cutting shaft unlocks and is able to be swung open, though it remains hinged. This prevents the risk of loss through separate parts. This model also features a black ceramic surface treatment which provides unparalleled hardness and durability. The black ceramic coating is designed to reduce the friction between metal surfaces, providing surgeons with a smooth, steady gliding action and a longer-lasting rongeur. The dark finish also reduces glare under operating room lights. The rongeur is a specialized instrument ideally suited for use in laminectomy procedures. It features small handles and thin footplate and is 40 degrees up which allows it to comfortably maneuver in the narrow spaces in and around the vertebral column. Laminectomies are performed for a number of reasons.
