Rotating Kerrison Shaft, 7″ (175mm) Bayonet, 1.5mm, 40° up Stainless Steel, Requires 70-2390 Micro

Rotating Kerrison Shaft, 7″ (175mm) Bayonet, 1.5mm, 40° Up, Stainless Steel – Requires 70-2390 Micro Handle is a professional-grade modular surgical instrument engineered for highly delicate 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 fully functional surgical instrument. The shaft features a 1.5mm bite size , making it ideal for microsurgical applications and decompression procedures requiring maximum precision. The fine bite profile enables surgeons to remove small amounts of bone and ligamentous tissue with exceptional control, helping preserve surrounding anatomical structures and sensitive neural elements. Its 40° upward-facing footplate is specifically designed to facilitate controlled bone resection beneath anatomical structures while providing a versatile working angle. This configuration enhances access to the spinal canal, neural foramina, and confined surgical corridors, allowing precise decompression with improved instrument positioning and visibility. The specialized bayonet design offsets the working tip from the handle, keeping the surgeon’s hand outside the direct line of sight. This significantly improves visualization of the operative field and is particularly beneficial during microscopic, minimally invasive, and complex spinal procedures where unobstructed viewing is essential. A key feature of this instrument is its rotating shaft mechanism , which allows surgeons to adjust the orientation of the cutting tip without repositioning the entire instrument. This capability improves maneuverability, facilitates access to difficult anatomical regions, and enhances efficiency during intricate decompression procedures. With a 7-inch (175mm) shaft length , the instrument provides an excellent balance between reach and precision. The extended working length allows access to deeper operative sites while maintaining exceptional control within confined anatomical spaces. The Kerrison shaft is particularly effective for laminectomy, laminotomy, spinal decompression, foraminotomy, microdiscectomy, spinal stenosis surgery, cervical decompression, lumbar decompression, thoracic spine procedures, and neurosurgical interventions . It is commonly used for the precise removal of lamina, osteophytes, ligamentum flavum, hypertrophic bone, and other structures contributing to neural compression. The precision-engineered cutting mechanism delivers smooth and controlled bone resection while providing excellent tactile feedback. This enables surgeons to perform delicate decompression procedures confidently around the spinal cord, nerve roots, and dura mater while minimizing unnecessary tissue disruption. Manufactured from premium surgical-grade stainless steel , the shaft offers outstanding 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, 7″ (175mm) Bayonet, 1.5mm, 40° 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 ultra-precise bone removal, enhanced surgical visibility, and professional-grade clinical reliability for advanced spinal and neurosurgical procedures.

It is used for ultra-precise bone removal and spinal decompression during spine surgery, neurosurgery, and orthopedic procedures involving delicate anatomical structures. What advantage does the 1.5mm bite size provide? The 1.5mm bite size allows highly controlled bone resection, making it ideal for microsurgical decompression and procedures performed near critical neural structures. What is the purpose of the 40° upward footplate? The 40° upward-facing footplate provides improved access to targeted anatomical structures and facilitates controlled decompression within confined surgical 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, 7″ (175mm) Bayonet, 1.5mm, 40° Up, Stainless Steel is fully reusable, autoclavable, and engineered to maintain precision, durability, and performance through repeated sterilization and long-term clinical use.
