The Neurosurgery Rotating Kerrison Shaft 6″ Bayonet 1mm 40° Up is a high-precision modular neurosurgical instrument designed for meticulous bone removal during advanced spinal, cranial, and microsurgical procedures. Engineered specifically for compatibility with the 70-2390 Micro Handle, this detachable rotating shaft delivers exceptional cutting accuracy, ergonomic handling, and dependable long-term performance. It is an indispensable instrument for neurosurgeons and spine surgeons who require precise bone excision while preserving delicate neural, vascular, and soft tissue structures.

Featuring an overall length of 6 inches (150mm), this Kerrison shaft is optimized for procedures requiring superior maneuverability in confined operative fields. The shorter shaft allows excellent tactile feedback and precise instrument control, making it particularly suitable for cervical spine surgery, minimally invasive spinal procedures, skull base surgery, and other microsurgical interventions where accuracy is critical.

The Bayonet shaft configuration enhances visualization by offsetting the surgeon’s hand away from the operative field. This ergonomic design creates a clear, unobstructed view when operating under a surgical microscope or magnification loupes, allowing improved access to deep anatomical structures without compromising visibility. The Bayonet profile also promotes a more comfortable hand position, reducing fatigue during prolonged surgical procedures.

Equipped with a 1mm footplate, this Kerrison shaft is designed for the most delicate bone removal applications. The ultra-fine bite enables incremental excision of cortical and cancellous bone while preserving surrounding anatomy. This small bite size is particularly valuable during microsurgical decompression procedures where maximum precision is required around the spinal cord, nerve roots, and other sensitive neurological structures.

The 40° up-biting jaw provides a gradual upward cutting angle, allowing controlled access beneath the lamina and adjacent bony structures. Compared to steeper jaw configurations, the 40° angle offers smoother engagement with bone surfaces and improved visualization during decompression procedures. This design is especially beneficial during laminectomy, laminotomy, foraminotomy, and minimally invasive spinal surgery where careful bone removal is essential for optimal clinical outcomes.

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 advanced rotating system enables precise orientation of the cutting jaw without requiring changes in hand position, improving ergonomics and facilitating access to difficult anatomical angles. The rotating mechanism enhances surgical efficiency, minimizes wrist strain, and provides greater control during intricate neurosurgical procedures.

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

The shaft is specifically engineered for seamless compatibility with the 70-2390 Micro Handle, providing a secure modular locking mechanism for quick attachment and removal during surgery. The interchangeable design 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 1mm, 40° up-biting jaw provides exceptional precision for delicate decompression procedures while protecting surrounding neurological structures and preserving healthy tissue.

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 precise cutting action, smooth mechanical operation, and structural integrity after repeated sterilization cycles.

The Neurosurgery Surgical Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 1mm, 40° Up, Stainless Steel, Requires 70-2390 Micro combines precision engineering, ergonomic Bayonet design, modular compatibility, and exceptional cutting accuracy. It is a trusted choice for neurosurgeons and spine specialists performing advanced spinal and cranial procedures where surgical precision and reliability are paramount.
