Rotating Kerrison Shaft, 7″ (175mm) Bayonet, 1.5mm

Rotating Kerrison Shaft, 7″ (175mm) Bayonet, 1.5mm, 90° 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 paired with the compatible 70-2390 Micro Handle to create a complete and functional surgical instrument. The shaft features a 1.5mm bite size , making it ideal for microsurgical applications and decompression procedures that demand exceptional precision. The small bite profile allows surgeons to remove minimal amounts of bone and ligamentous tissue while maintaining maximum control around sensitive neural structures, including nerve roots, the spinal cord, and dura mater. Its 90° upward-facing footplate is specifically designed to provide optimal access beneath bony structures and within confined spinal anatomical spaces. This configuration allows controlled decompression of the spinal canal and neural foramina while preserving surrounding tissues and maintaining excellent visualization. The specialized bayonet design offsets the working tip from the handle, keeping the surgeon’s hand out of the direct line of sight. This improves visualization of the operative field and is particularly beneficial during microscopic, endoscopic, and minimally invasive 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 enhances maneuverability, improves access to difficult anatomical regions, and increases procedural efficiency during complex decompression procedures. With a 7-inch (175mm) shaft length , the instrument provides an ideal balance of reach and control. The length is particularly suited for cervical, thoracic, and lumbar spine procedures where precise bone removal is required within deep and confined operative 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, 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 with confidence and accuracy while minimizing unnecessary tissue disruption. 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, 7″ (175mm) Bayonet, 1.5mm, 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 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 tissues. What is the purpose of the 90° upward footplate? The 90° upward-facing footplate provides improved access beneath bony structures and facilitates precise decompression within narrow spinal anatomical spaces. Why is the bayonet design beneficial? The bayonet configuration improves visualization by keeping the surgeon’s hand outside the direct viewing path, allowing a clearer and less obstructed view of the operative field. Why is the shaft rotatable? The rotating mechanism enables adjustment of the cutting tip orientation 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, 90° Up, Stainless Steel is fully reusable, autoclavable, and engineered to maintain precision, durability, and performance through repeated sterilization and long-term clinical use.
