The Neurosurgery Rotating Kerrison Shaft 6″ Bayonet 1.5mm 40° Up is a high-precision modular neurosurgical instrument designed for controlled bone removal during complex spinal and cranial procedures. Engineered exclusively for compatibility with the 70-2390 Micro Handle, this detachable rotating shaft combines exceptional cutting accuracy, ergonomic handling, and superior durability to meet the rigorous demands of modern neurosurgery. It is an indispensable instrument for neurosurgeons and spine surgeons who require meticulous bone excision while protecting delicate neural structures and surrounding soft tissues.

With an overall length of 6 inches (150mm), this rotating Kerrison shaft provides outstanding maneuverability within confined operative fields. Its compact profile allows surgeons to maintain excellent tactile feedback and precise control when performing delicate procedures involving the cervical spine, thoracic spine, lumbar spine, and skull base. The shorter shaft length is particularly beneficial during minimally invasive procedures where accurate instrument handling is critical.

The Bayonet shaft configuration is specifically designed to improve visualization by positioning the surgeon’s hand away from the direct line of sight. This offset profile creates an unobstructed view of the operative field when working under an operating microscope or surgical loupes. Enhanced visibility allows more accurate bone removal while improving surgeon comfort and reducing hand obstruction during lengthy microsurgical procedures.

The instrument features a 1.5mm footplate, making it ideal for delicate bone excision requiring precise control. The narrow bite allows surgeons to remove small sections of cortical and cancellous bone incrementally, preserving healthy anatomical structures while achieving effective decompression. The 1.5mm bite size provides an excellent balance between precision and efficiency, making it suitable for procedures where gradual bone removal is essential to protect surrounding neurological tissues.

Its 40° up-biting jaw is engineered to provide a gradual upward cutting angle beneath the lamina and adjacent bony structures. Compared to steeper jaw configurations, the 40° angle offers smoother engagement with bone and excellent visualization throughout the cutting process. This design is particularly advantageous during laminectomy, laminotomy, foraminotomy, cervical decompression, lumbar decompression, microdiscectomy, and minimally invasive spinal surgery, allowing surgeons to perform controlled decompression while minimizing unnecessary tissue manipulation.

One of the defining features of this instrument is its 360° rotating shaft mechanism, enabling the working tip to rotate independently while the handle remains stationary. This advanced rotating capability allows precise positioning of the cutting jaw without requiring changes in hand position, improving ergonomics and facilitating access to difficult anatomical angles. The rotating design reduces surgeon fatigue during extended procedures while increasing overall surgical efficiency and precision.

Manufactured from premium surgical-grade stainless steel, the Rotating Kerrison Shaft provides excellent mechanical strength, corrosion resistance, and long-term clinical reliability. Precision manufacturing ensures smooth rotational movement, accurate jaw alignment, and dependable 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 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 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 1.5mm, 40° up-biting jaw provides exceptional control for delicate decompression procedures while preserving surrounding neurological structures and ensuring optimal surgical outcomes.

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

The Neurosurgery Surgical Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 1.5mm, 40° Up, Stainless Steel, Requires 70-2390 Micro combines precision engineering, ergonomic Bayonet design, modular compatibility, and exceptional cutting performance. It is a trusted instrument for neurosurgeons and spine specialists performing advanced spinal and cranial procedures where precision, reliability, and efficiency are essential.
