The Neurosurgery Rotating Kerrison Shaft 6″ Bayonet 1.5mm 90° Up is a precision-engineered modular neurosurgical instrument developed for controlled bone removal during complex spinal, cranial, and microsurgical procedures. Designed specifically for compatibility with the 70-2390 Micro Handle, this detachable rotating shaft delivers superior cutting accuracy, outstanding maneuverability, and long-lasting durability for demanding surgical environments. It is an essential instrument for neurosurgeons and spine specialists performing decompression procedures where meticulous bone excision is required while protecting delicate neural and vascular structures.

With an overall length of 6 inches (150mm), this Kerrison shaft provides excellent maneuverability in confined operative fields. The shorter shaft design offers enhanced tactile feedback and precise instrument control, making it ideal for cervical spine surgery, minimally invasive spinal procedures, skull base surgery, and other microsurgical interventions that require exceptional precision and stability.

The Bayonet shaft configuration is specifically designed to improve visualization by positioning the surgeon’s hand away from the operative field. This offset profile provides an unobstructed view under surgical microscopes and magnification loupes, allowing greater accuracy during delicate procedures. The ergonomic Bayonet design also reduces hand obstruction and enhances comfort during prolonged operations performed within narrow surgical corridors.

Equipped with a 1.5mm footplate, this Kerrison shaft is optimized for fine and controlled bone removal. The narrow bite size enables surgeons to excise small portions of cortical and cancellous bone with exceptional precision while preserving surrounding healthy tissue. The 1.5mm bite offers an ideal balance between delicate bone excision and procedural efficiency, making it highly suitable for microsurgical decompression around the spinal cord and nerve roots.

The 90° up-biting jaw provides direct upward access beneath the lamina and adjacent bony structures, allowing surgeons to remove bone efficiently from difficult-to-reach areas. This jaw configuration is particularly beneficial during laminectomy, laminotomy, foraminotomy, cervical decompression, lumbar decompression, and minimally invasive spinal surgery, where precise upward cutting is required to achieve adequate decompression while minimizing trauma to surrounding anatomical structures.

A key feature 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 precise orientation of the cutting jaw without changing hand position, improving ergonomics and facilitating access to challenging surgical angles. The rotating mechanism reduces surgeon fatigue while increasing procedural efficiency and maintaining consistent cutting accuracy throughout the operation.

Manufactured from premium surgical-grade stainless steel, the Rotating Kerrison Shaft provides outstanding strength, corrosion resistance, and long-term clinical reliability. Precision machining ensures smooth rotational movement, accurate jaw alignment, and dependable cutting performance after repeated use. The polished stainless steel finish supports efficient cleaning and complies with modern hospital sterilization and infection control standards.

The shaft is engineered exclusively for use with the 70-2390 Micro Handle, providing a secure modular locking mechanism for quick attachment and removal during surgery. This interchangeable system allows surgeons to utilize multiple shaft lengths, bite sizes, and jaw configurations with a single handle, improving operating room efficiency while reducing instrument inventory requirements.

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 1.5mm, 90° up-biting jaw provides exceptional precision for controlled decompression while preserving surrounding neurological structures and maintaining excellent surgical visibility.

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 reliable long-term performance while maintaining cutting precision, smooth mechanical operation, and structural integrity after repeated sterilization cycles.

The Neurosurgery Surgical Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 1.5mm, 90° Up, Stainless Steel, Requires 70-2390 Micro combines advanced engineering, ergonomic Bayonet design, modular compatibility, and exceptional cutting precision. It is a trusted choice for neurosurgeons and spine surgeons seeking reliable performance during advanced spinal and cranial procedures.
