The Neurosurgery Rotating Kerrison Shaft 6″ Bayonet 3mm 90° Up is a precision-engineered modular neurosurgical instrument developed for controlled bone excision during complex spinal, cranial, and microsurgical procedures. Specifically designed for compatibility with the 70-2390 Micro Handle, this detachable rotating shaft provides exceptional cutting accuracy, ergonomic handling, and reliable long-term performance. It is an essential instrument for neurosurgeons and spine specialists who require meticulous bone removal while preserving delicate neural structures and surrounding soft tissues.

The instrument features a 6-inch (150mm) Bayonet shaft, offering excellent maneuverability and enhanced visualization in confined operative fields. The Bayonet design offsets the surgeon’s hand away from the direct line of sight, creating a clear view of the surgical site during microscope-assisted procedures. This ergonomic configuration improves precision, minimizes hand obstruction, and enhances control during delicate spinal and cranial surgeries performed through narrow surgical corridors.

Equipped with a 3mm footplate, this Kerrison shaft provides precise bone removal with an ideal balance between efficiency and accuracy. The 3mm bite size is particularly suited for controlled excision of cortical and cancellous bone during decompression procedures where preservation of surrounding anatomy is essential. It enables surgeons to remove bone incrementally while maintaining exceptional tactile feedback and surgical precision.

The 90° up-biting jaw is designed to provide direct upward access beneath the lamina and adjacent bony structures. This configuration allows efficient bone removal from areas that are difficult to access with conventional straight instruments, making it highly effective during laminectomy, laminotomy, and foraminotomy procedures. The upward cutting angle helps achieve adequate decompression while minimizing unnecessary manipulation of surrounding neurological tissues.

A distinguishing feature of this instrument is its 360° rotating shaft mechanism, allowing the working tip to rotate freely while the handle remains stationary. This rotating capability enables precise orientation of the cutting jaw without repositioning the surgeon’s hand, improving ergonomics and facilitating access to challenging anatomical angles. The rotating mechanism reduces wrist fatigue during prolonged procedures while enhancing overall surgical efficiency and control.

Manufactured from premium surgical-grade stainless steel, the Rotating Kerrison Shaft offers exceptional durability, corrosion resistance, and mechanical reliability. Precision machining ensures smooth rotational movement, accurate jaw alignment, and consistent cutting performance throughout repeated clinical use. The polished stainless steel finish supports easy 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 system that allows rapid attachment and removal during surgery. The interchangeable design enables surgeons to utilize multiple shaft lengths, bite sizes, and jaw configurations with a single handle, improving workflow efficiency and increasing procedural versatility while reducing instrument inventory.

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 3mm, 90° up-biting jaw provides exceptional precision for controlled bone excision while maintaining maximum protection of adjacent neural and vascular structures.

Designed as a reusable surgical instrument, the Rotating Kerrison Shaft is fully compatible with standard hospital sterilization procedures, including steam autoclaving. Its premium stainless steel construction ensures long-lasting clinical performance while maintaining precise cutting action and smooth mechanical operation after repeated cleaning and sterilization cycles.

The Neurosurgery Surgical Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 3mm, 90° Up, Stainless Steel, Requires 70-2390 Micro combines advanced engineering, ergonomic Bayonet design, modular compatibility, and precision cutting capability. It is an indispensable instrument for neurosurgeons and spine surgeons performing advanced spinal and cranial procedures requiring exceptional control and reliability.
