The Neurosurgery Rotating Kerrison Shaft 6″ Bayonet 4mm 90° Up is a precision-engineered modular neurosurgical instrument developed for controlled bone removal during advanced spinal, cranial, and microsurgical procedures. Designed exclusively for compatibility with the 70-2390 Micro Handle, this detachable rotating shaft combines exceptional cutting accuracy, ergonomic handling, and long-term durability to meet the rigorous demands of modern neurosurgery. It is widely utilized by neurosurgeons and spine surgeons for delicate decompression procedures requiring meticulous bone excision while preserving surrounding neural structures.

With an overall length of 6 inches (150mm), this Kerrison shaft offers excellent maneuverability within compact surgical corridors. The shorter shaft design provides superior control and tactile feedback, making it particularly effective for microsurgical procedures performed in confined anatomical spaces. It is ideally suited for cervical spine surgery, cranial procedures, and minimally invasive spinal techniques where precision and instrument responsiveness are essential.

The Bayonet shaft configuration enhances the surgeon’s view by offsetting the hand away from the operative field. This ergonomic design provides a clear, unobstructed line of sight when operating under surgical microscopes or magnification systems, improving visualization of delicate anatomical structures. The Bayonet profile also facilitates comfortable instrument handling during lengthy procedures, reducing hand obstruction while enhancing surgical precision.

The instrument incorporates a 4mm footplate with a 90° up-biting jaw, providing an excellent combination of cutting efficiency and precise bone removal. The 4mm bite size allows surgeons to excise moderate amounts of cortical and cancellous bone with exceptional control, making it ideal for decompression procedures requiring accurate bone resection. The 90° up-biting jaw is specifically designed to remove bone directly beneath the lamina and adjacent structures, enabling effective decompression while minimizing unnecessary manipulation of surrounding soft tissues and neural elements.

A defining feature of this instrument is its 360° rotating shaft mechanism, which allows the working tip to rotate smoothly without repositioning the handle. This advanced rotational capability enables surgeons to precisely orient the cutting jaw to match the operative anatomy, improving access within narrow surgical corridors and reducing wrist movement during prolonged procedures. The result is enhanced surgical efficiency, improved ergonomics, and greater procedural accuracy.

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

This modular shaft is specifically engineered for use with the 70-2390 Micro Handle, creating a secure locking connection that enables quick attachment and removal during surgery. The interchangeable system allows 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 spinal surgery, cranial bone removal, and skull base procedures. The 4mm, 90° up-biting jaw provides excellent bone-cutting performance while maintaining precise control around delicate neurological structures.

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 and smooth mechanical function after repeated cleaning and sterilization cycles.

The Neurosurgery Surgical Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 4mm, 90° Up, Stainless Steel, Requires 70-2390 Micro combines advanced engineering, ergonomic Bayonet design, modular compatibility, and precision cutting performance. It is an indispensable instrument for neurosurgeons and spine specialists seeking dependable bone removal during complex spinal and cranial procedures.
