The Neurosurgery Rotating Kerrison Shaft 6″ Bayonet 5mm 40° Up is a precision-engineered modular neurosurgical instrument developed for accurate bone removal during advanced spinal, cranial, and microsurgical procedures. Specifically designed for compatibility with the 70-2390 Micro Handle, this detachable rotating shaft provides outstanding cutting performance, ergonomic handling, and long-term reliability. It is an essential instrument for neurosurgeons and spine surgeons performing decompression procedures where controlled bone excision and preservation of surrounding neural structures are critical.

Featuring an overall length of 6 inches (150mm), this Kerrison shaft offers excellent maneuverability within compact operative fields. The shorter shaft length allows surgeons to maintain precise instrument control while working in confined anatomical spaces, making it especially beneficial for cervical spine procedures, cranial surgery, and minimally invasive spinal techniques. Its compact profile provides excellent tactile feedback and smooth instrument handling throughout delicate microsurgical procedures.

The Bayonet shaft configuration is specifically designed to enhance visualization by offsetting the surgeon’s hand from the operative field. This ergonomic design provides an unobstructed view of the surgical site when working under an operating microscope or surgical loupes. Improved visibility enables greater surgical precision, particularly during procedures involving delicate neural structures and limited surgical corridors.

The instrument features a 5mm footplate combined with a 40° up-biting jaw, offering an ideal balance between cutting efficiency and surgical precision. The 5mm bite allows effective removal of moderate amounts of cortical and cancellous bone while maintaining excellent control throughout the procedure. The 40° upward jaw angle provides a gradual approach for bone excision beneath the lamina and adjacent bony structures, allowing surgeons to perform decompression procedures with improved visibility and minimal disruption to surrounding soft tissue. This configuration is especially useful during laminectomy, laminotomy, foraminotomy, and other spinal decompression procedures requiring precise bone removal.

One of the instrument’s key features is its 360° rotating shaft mechanism, which allows the cutting jaw to rotate smoothly into the desired position without changing the surgeon’s hand position. This rotational capability improves access to difficult anatomical angles while reducing wrist movement and operator fatigue. The rotating design enhances surgical efficiency by enabling rapid jaw orientation adjustments during complex neurosurgical procedures.

Manufactured from premium surgical-grade stainless steel, the Rotating Kerrison Shaft provides 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 protocols.

The shaft is engineered exclusively for use with the 70-2390 Micro Handle, providing a secure modular locking mechanism that allows rapid attachment and removal during surgery. The interchangeable system enables surgeons to use 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 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 5mm, 40° up-biting jaw is particularly effective for controlled decompression and precise bone excision while protecting adjacent neurological 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 dependable long-term performance while maintaining cutting precision and smooth mechanical operation after repeated cleaning and sterilization cycles.

The Neurosurgery Surgical Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 5mm, 40° Up, Stainless Steel, Requires 70-2390 Micro combines advanced engineering, ergonomic Bayonet design, modular compatibility, and exceptional cutting accuracy. It is a trusted instrument for neurosurgeons and spine specialists performing complex spinal and cranial procedures where precision, visibility, and reliability are essential.
