The Neurosurgery Rotating Kerrison Shaft 6″ Bayonet 5mm 90° Up is a high-precision modular neurosurgical instrument engineered for efficient bone removal during advanced spinal, cranial, and microsurgical procedures. Designed for seamless compatibility with the 70-2390 Micro Handle, this detachable rotating shaft delivers superior cutting accuracy, ergonomic control, and reliable durability for demanding surgical environments. It is an essential instrument for neurosurgeons and spine surgeons performing decompression procedures that require controlled bone excision while protecting delicate neural structures.

With an overall length of 6 inches (150mm), this Kerrison shaft is optimized for procedures requiring enhanced maneuverability in compact operative fields. The shorter shaft length offers outstanding control during microsurgical interventions, making it particularly suitable for cervical spine surgery, cranial procedures, and minimally invasive spinal techniques. Its compact design allows surgeons to maintain excellent tactile feedback while operating in confined anatomical spaces.

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 design provides an unobstructed view of the surgical field under an operating microscope or surgical loupes, enabling greater precision during delicate neurosurgical procedures. The ergonomic Bayonet profile also enhances instrument handling by reducing hand obstruction and improving access to deep surgical targets.

The instrument features a 5mm footplate combined with a 90° up-biting jaw, providing efficient removal of moderate to larger amounts of bone while maintaining excellent control. The wider 5mm bite allows surgeons to remove bone more efficiently during decompression procedures, reducing operative time without compromising precision. The 90° up-biting jaw is designed to remove bone directly beneath the lamina and surrounding anatomical structures, making it particularly valuable during laminectomy, laminotomy, and foraminotomy procedures.

A defining feature of this instrument is its 360° rotating shaft mechanism, allowing the cutting tip to rotate smoothly into the desired position while the handle remains stationary. This rotational capability enables precise jaw orientation without changing hand position, improving ergonomics and allowing surgeons to access difficult anatomical angles more efficiently. The rotating mechanism reduces wrist fatigue during lengthy procedures while enhancing surgical flexibility and precision.

Manufactured from premium surgical-grade stainless steel, the Rotating Kerrison Shaft provides exceptional strength, corrosion resistance, and long-term reliability. Precision machining ensures accurate jaw alignment, smooth rotational movement, and consistent cutting performance throughout repeated clinical use. The polished stainless steel finish facilitates cleaning and supports compliance with modern hospital sterilization protocols.

The shaft is specifically designed for use with the 70-2390 Micro Handle, creating a secure modular connection that enables rapid 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 workflow efficiency while reducing overall 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 spinal surgery, cranial bone removal, and skull base procedures. The 5mm, 90° up-biting jaw provides excellent cutting capacity for controlled decompression while preserving adjacent neural and soft tissue structures.

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 accuracy and smooth mechanical function after repeated cleaning and sterilization cycles.

The Neurosurgery Surgical Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 5mm, 90° Up, Stainless Steel, Requires 70-2390 Micro combines precision engineering, modular compatibility, ergonomic Bayonet design, and superior cutting performance. It is a trusted instrument for neurosurgeons and spine specialists seeking reliable bone removal during complex spinal and cranial procedures.
