Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 2mm, 90° Up, Stainless Steel, Requires 70-2390 Micro

Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 2mm, 90° Up, Stainless Steel – Requires 70-2390 Micro Handle is a professional-grade modular surgical instrument engineered for highly precise spinal decompression, neurosurgical procedures, and orthopedic bone resection. Designed as a shaft-only component within a modular Kerrison Rongeur system, this instrument must be used with the compatible 70-2390 Micro Handle to create a complete and functional surgical instrument. The shaft features a 2mm bite size , making it ideal for delicate decompression procedures requiring precise and controlled bone removal. The smaller bite profile allows surgeons to excise bone and ligamentous tissue with exceptional accuracy while preserving surrounding anatomical structures and neural elements. Its 90° upward-facing footplate is specifically designed to facilitate controlled bone resection beneath overlying anatomical structures. This configuration provides excellent access to the spinal canal, neural foramina, and confined surgical spaces, enabling surgeons to perform precise decompression while maintaining optimal visualization. The specialized bayonet design offsets the working tip from the handle, keeping the surgeon’s hand outside the direct line of sight. This design significantly improves visualization of the operative field and is particularly advantageous during microscopic, minimally invasive, and complex spinal procedures where unobstructed viewing is critical. A key feature of this instrument is its rotating shaft mechanism , which enables surgeons to adjust the orientation of the cutting tip without repositioning the entire instrument. This capability improves maneuverability, facilitates access to difficult anatomical locations, and enhances procedural efficiency during intricate decompression surgeries. With a 6-inch (150mm) shaft length , the instrument offers excellent control and responsiveness while maintaining adequate reach for a variety of spinal procedures. The compact length is particularly beneficial when operating within narrow and confined surgical corridors requiring meticulous instrument handling. The Kerrison shaft is particularly effective for laminectomy, laminotomy, spinal decompression, foraminotomy, microdecompression, spinal stenosis surgery, cervical decompression, lumbar decompression, thoracic spine procedures, and neurosurgical interventions . It is commonly used for removing lamina, osteophytes, ligamentum flavum, hypertrophic bone, and other structures contributing to neural compression. The precision-engineered cutting mechanism provides smooth and controlled bone resection while delivering excellent tactile feedback. This allows surgeons to perform delicate decompression procedures confidently around the spinal cord, dura mater, and nerve roots. Manufactured from premium surgical-grade stainless steel , the shaft offers exceptional durability, corrosion resistance, and long-term clinical reliability. Precision manufacturing ensures smooth rotational performance, dependable cutting action, and consistent functionality through repeated sterilization cycles and routine surgical use. The polished surgical finish facilitates efficient cleaning and supports compatibility with standard hospital sterilization protocols. Fully reusable and autoclavable, the Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 2mm, 90° Up, Stainless Steel is suitable for hospitals, spine centers, orthopedic departments, neurosurgical facilities, and teaching institutions worldwide. Trusted by spine surgeons, orthopedic specialists, and neurosurgeons, this modular instrument component delivers precise bone removal, enhanced surgical visibility, and professional-grade clinical reliability for advanced spinal and neurosurgical procedures.

It is used for precise bone removal and spinal decompression during spine surgery, neurosurgery, and orthopedic procedures involving delicate anatomical structures. What advantage does the 2mm bite size provide? The 2mm bite size allows highly controlled and accurate bone resection, making it ideal for decompression procedures performed near critical neural tissues. What is the purpose of the 90° upward footplate? The 90° upward-facing footplate improves access beneath bony structures and facilitates precise decompression within confined spinal anatomical spaces. Why is the bayonet design beneficial? The bayonet configuration improves surgical visibility by keeping the surgeon’s hand outside the direct viewing path, providing a clearer and less obstructed view of the operative field. Why is the shaft rotatable? The rotating mechanism allows surgeons to adjust the orientation of the cutting tip without repositioning the entire instrument, improving maneuverability, flexibility, and surgical precision. Does this product include a handle? No. This is a shaft-only component and requires the compatible 70-2390 Micro Handle to function as a complete Kerrison Rongeur. Is the instrument reusable? Yes. The Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 2mm, 90° Up, Stainless Steel is fully reusable, autoclavable, and engineered to maintain precision, durability, and performance through repeated sterilization and long-term clinical use.
