Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 1mm, 90° Up, Stainless Steel – Requires 70-2390 Micro

Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 1mm, 90° Up, Stainless Steel – Requires 70-2390 Micro Handle is a professional-grade surgical instrument shaft engineered for highly precise bone resection and decompression procedures in spine surgery, neurosurgery, and orthopedic interventions. Designed as part of a modular Kerrison Rongeur system, this shaft must be used with the compatible 70-2390 Micro Handle to create a complete functional instrument. The instrument features a 1mm bite size , allowing surgeons to perform extremely delicate and controlled bone removal in anatomically sensitive areas. The small bite profile is particularly valuable when operating near neural structures where precision is critical and preservation of surrounding tissues is essential. The 90° upward-facing footplate provides enhanced access beneath bone structures and allows controlled resection in confined surgical corridors. This configuration is especially useful during spinal decompression procedures where bone must be removed while maintaining clear visualization of neural elements. The bayonet shaft design offsets the working end from the surgeon’s line of sight, improving visualization within the operative field. By positioning the handle away from the surgical target, the bayonet configuration helps maintain an unobstructed view during microscopic and minimally invasive spinal procedures. A key feature of this instrument is its rotating shaft mechanism , which allows surgeons to adjust the orientation of the cutting footplate 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 6-inch (150mm) shaft length , the instrument offers excellent reach while maintaining precise control. The length is suitable for both open and minimally invasive spine procedures requiring accurate bone removal within deep operative sites. The Kerrison shaft is particularly effective for laminectomy, laminotomy, spinal decompression, foraminotomy, spinal stenosis surgery, cervical spine surgery, thoracic spine surgery, lumbar spine surgery, and neurosurgical procedures . Its precision cutting mechanism enables controlled removal of lamina, ligamentous tissue, osteophytes, and other compressive structures. Manufactured from premium surgical-grade stainless steel , the shaft provides exceptional durability, corrosion resistance, and long-term clinical reliability. Precision engineering ensures smooth cutting action, consistent performance, and dependable functionality through repeated sterilization cycles and routine surgical use. The polished surgical finish facilitates thorough cleaning and supports compliance with standard hospital sterilization protocols. Fully reusable and autoclavable, the Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 1mm, 90° Up, Stainless Steel is suitable for hospitals, spine centers, neurosurgical facilities, orthopedic departments, and teaching institutions worldwide. Trusted by spine surgeons and neurosurgeons, this instrument component delivers precise bone removal, superior visibility, and professional-grade reliability for advanced spinal and neurosurgical procedures.
