The Neurosurgery Rotating Kerrison Shaft 6″ Bayonet 1mm 90° Up is a precision-engineered modular neurosurgical instrument developed for extremely delicate bone removal during advanced spinal, cranial, and microsurgical procedures. Designed specifically for compatibility with the 70-2390 Micro Handle, this detachable rotating shaft provides exceptional cutting accuracy, outstanding maneuverability, and dependable durability for demanding surgical environments. It is an essential instrument for neurosurgeons and spine specialists performing procedures where maximum precision is required to protect surrounding neurological structures.

The instrument features a 6-inch (150mm) Bayonet shaft, offering superior access and excellent visualization in deep operative fields. The Bayonet configuration positions the surgeon’s hand away from the direct surgical line of sight, providing an unobstructed view when working under an operating microscope or surgical loupes. This ergonomic design improves instrument control, enhances precision, and allows comfortable handling during prolonged microsurgical procedures performed through narrow anatomical corridors.

Equipped with a 1mm footplate, this Kerrison shaft is specifically designed for the most delicate bone removal applications. The ultra-fine bite size allows surgeons to remove extremely small sections of cortical and cancellous bone with exceptional control while preserving surrounding neural tissue, blood vessels, and soft tissue structures. The 1mm footplate is particularly valuable during microsurgical decompression where gradual bone removal is necessary to maintain surgical safety and achieve optimal clinical outcomes.

The 90° up-biting jaw provides direct upward access beneath the lamina and adjacent bony anatomy, enabling efficient removal of bone from difficult-to-reach areas. This configuration is ideal for procedures requiring direct upward cutting beneath overlying structures while maintaining excellent visibility of the operative field. The upward jaw orientation supports precise decompression during cervical, thoracic, and lumbar spine surgery, allowing surgeons to work confidently around sensitive neurological anatomy.

One of the most significant features of this instrument is its 360° rotating shaft mechanism, allowing the working tip to rotate independently while the handle remains stationary. This innovative design enables surgeons to precisely orient the cutting jaw without changing hand position, improving ergonomics and facilitating access to challenging anatomical angles. The rotating mechanism minimizes wrist fatigue during lengthy procedures while increasing efficiency and precision throughout the operation.

Manufactured from premium surgical-grade stainless steel, the Rotating Kerrison Shaft provides exceptional durability, corrosion resistance, and long-term clinical reliability. Precision manufacturing ensures accurate jaw alignment, smooth rotational performance, and consistent cutting action throughout repeated surgical use. The polished stainless steel finish supports efficient cleaning and complies with modern hospital sterilization and infection control protocols.

The shaft is specifically engineered for seamless compatibility with the 70-2390 Micro Handle, creating a secure modular connection that allows rapid attachment and removal during surgery. This interchangeable modular system enables surgeons to utilize multiple shaft lengths, bite sizes, and jaw configurations with a single handle, improving workflow efficiency while reducing overall instrument inventory.

The Neurosurgery Surgical Rotating Kerrison Shaft is widely used during laminectomy, laminotomy, spinal decompression, cervical spine surgery, thoracic spine surgery, lumbar spine surgery, foraminotomy, microdiscectomy, minimally invasive spine surgery, cranial bone removal, and skull base procedures. The 1mm, 90° up-biting jaw is particularly valuable for microsurgical decompression requiring exceptionally delicate bone removal around critical neural and vascular structures.

As a reusable surgical instrument, the Rotating Kerrison Shaft is fully compatible with standard hospital sterilization methods, including steam autoclaving. Its premium stainless steel construction ensures reliable long-term performance while maintaining precise cutting capability and smooth mechanical function after repeated cleaning and sterilization cycles.

The Neurosurgery Surgical Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 1mm, 90° Up, Stainless Steel, Requires 70-2390 Micro combines advanced engineering, ergonomic Bayonet design, modular compatibility, and unmatched cutting precision. It is a trusted choice for neurosurgeons and spine surgeons performing highly delicate spinal and cranial procedures where surgical accuracy and reliability are of the utmost importance.
