Rotating Kerrison Shaft, 7″ (175mm) Bayonet, 3mm, 90° Up, Stainless Steel, Requires 70-2390 Micro

Rotating Kerrison Shaft, 7″ (175mm) Bayonet, 3mm, 90° Up, Stainless Steel – Requires 70-2390 Micro Handle is a professional-grade modular surgical instrument engineered for advanced 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 3mm bite size , offering an excellent balance between precision and efficient tissue removal. This size allows surgeons to perform controlled bone resection while maintaining the accuracy required when operating near sensitive neural structures. It is particularly suitable for routine decompression procedures where both precision and procedural efficiency are essential. The instrument incorporates a 90° upward-facing footplate , specifically designed to facilitate access beneath bony structures and within confined spinal anatomical spaces. This configuration allows surgeons to perform controlled decompression of the spinal canal and neural foramina while maintaining excellent visualization of surrounding tissues. Its specialized bayonet design offsets the working end from the handle, improving visibility by keeping the surgeon’s hand outside the direct line of sight. This configuration is especially valuable during microscopic and minimally invasive spinal procedures where unobstructed visualization is critical. A key feature of this instrument is the rotating shaft mechanism , which allows surgeons to adjust the orientation of the cutting tip without repositioning the entire instrument. This enhanced maneuverability improves access to difficult anatomical locations and supports more efficient surgical workflow during complex decompression procedures. With a 7-inch (175mm) shaft length , the instrument offers an ideal combination of reach and control. The length is particularly well suited for cervical, thoracic, and lumbar spine procedures requiring precise bone removal within deep but confined operative fields. The Kerrison shaft is particularly effective for laminectomy, laminotomy, spinal decompression, foraminotomy, spinal stenosis surgery, cervical spine surgery, lumbar decompression, thoracic spine procedures, and neurosurgical interventions . It is commonly used for removing lamina, hypertrophic bone, osteophytes, ligamentum flavum, and other structures causing 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, nerve roots, and dura mater. 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, 3mm, 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, superior visibility, and professional-grade clinical reliability for advanced spinal and neurosurgical procedures.

It is used for controlled bone removal and spinal decompression during spine surgery, neurosurgery, and orthopedic procedures. What advantage does the 3mm bite size provide? The 3mm bite size offers an ideal balance between precision and efficiency, allowing controlled bone removal while maintaining excellent surgical accuracy. 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 confined spinal spaces. Why is the bayonet design beneficial? The bayonet configuration improves surgical visibility by keeping the surgeon’s hand out of the direct line of sight, allowing a clearer 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 and access during surgery. 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, 3mm, 90° Up, Stainless Steel is fully reusable, autoclavable, and designed to maintain precision, durability, and performance through repeated sterilization and long-term clinical use.
