The Neurosurgery Rotating Kerrison Shaft 6″ Bayonet 2mm 90° Up is a precision-engineered modular neurosurgical instrument specifically designed for meticulous bone removal during advanced spinal, cranial, and microsurgical procedures. Manufactured for seamless compatibility with the 70-2390 Micro Handle, this detachable rotating shaft offers exceptional cutting accuracy, ergonomic control, and outstanding durability. It is an indispensable instrument for neurosurgeons and spine specialists who require delicate bone excision while safeguarding surrounding neural structures and soft tissues.

The instrument features a 6-inch (150mm) Bayonet shaft, providing excellent maneuverability and unobstructed visualization in deep surgical fields. The Bayonet profile positions the surgeon’s hand away from the operative site, ensuring a clear line of sight when working under surgical microscopes or magnification systems. This ergonomic design significantly improves precision and control during complex neurosurgical procedures, particularly in narrow anatomical corridors where visibility is essential.

Equipped with a 2mm footplate, this Kerrison shaft is ideal for highly delicate bone removal. The fine bite size enables surgeons to remove very small portions of cortical and cancellous bone with exceptional control, making it particularly suitable for procedures requiring meticulous decompression around sensitive neurological structures. The 2mm bite minimizes unnecessary bone removal while providing the accuracy required for microsurgical applications.

The 90° up-biting jaw is engineered to provide direct upward access beneath the lamina and surrounding bony anatomy. This configuration allows surgeons to remove bone efficiently from difficult-to-reach areas while maintaining excellent visualization and precise instrument control. The upward cutting action is especially valuable during laminectomy, laminotomy, foraminotomy, and other decompression procedures where complete access beneath overlying bone is required.

A defining feature of this instrument is its 360° rotating shaft mechanism, which allows the working tip to rotate smoothly while the handle remains stationary. This advanced rotational capability enables precise positioning of the cutting jaw without changing hand placement, improving ergonomics and reducing wrist fatigue during lengthy surgical procedures. The rotating design enhances access to challenging anatomical angles while increasing procedural efficiency and surgical accuracy.

Manufactured from premium surgical-grade stainless steel, the Rotating Kerrison Shaft delivers exceptional mechanical strength, corrosion resistance, and long-term clinical reliability. Precision machining ensures accurate jaw alignment, smooth rotational movement, and consistent cutting performance 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 designed for use with the 70-2390 Micro Handle, providing a secure modular locking mechanism that enables rapid attachment and removal during surgery. This interchangeable system allows surgeons to switch between different shaft lengths, bite sizes, and jaw configurations while using the same handle, improving workflow efficiency and increasing procedural versatility.

The Neurosurgery Surgical Rotating Kerrison Shaft is commonly 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 2mm, 90° up-biting jaw is particularly effective for precision decompression procedures where controlled bone removal around delicate neurological structures is essential.

Designed 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 dependable long-term performance while maintaining cutting precision and smooth mechanical operation after repeated cleaning and sterilization cycles.

The Neurosurgery Surgical Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 2mm, 90° Up, Stainless Steel, Requires 70-2390 Micro combines advanced engineering, ergonomic Bayonet design, modular compatibility, and exceptional cutting precision. It is an essential instrument for neurosurgeons and spine surgeons performing advanced spinal and cranial procedures where accuracy, reliability, and surgical control are critical.
