Rotating Kerrison Shaft, 8″ (200mm) Straight, 4mm, 40° Up, Panther – Shaft Only – Requires 70-2390P Micro

Rotating Kerrison Shaft, 8″ (200mm) Straight, 4mm, 40° Up, Panther – Shaft Only – Requires 70-2390P Micro Handle is a professional-grade modular surgical instrument engineered for advanced spinal decompression, neurosurgery, and orthopedic bone resection procedures. Designed as a shaft-only component within a modular Kerrison Rongeur system, this instrument requires the compatible 70-2390P Micro Handle for complete assembly and operation. The shaft features a 4mm bite size , providing an ideal balance between precision and efficiency during bone removal. This size allows surgeons to perform controlled decompression while removing sufficient tissue volume to maintain procedural efficiency, making it suitable for both delicate and routine spinal procedures. Its 40° upward-facing footplate is specifically designed to facilitate access beneath bony structures and within confined anatomical spaces. This configuration allows controlled resection of lamina, osteophytes, and ligamentous tissue while maintaining clear visualization of surrounding neural structures. The straight shaft design provides direct instrument alignment and predictable handling characteristics. This configuration is particularly advantageous during open and minimally invasive spinal procedures where accurate instrument orientation and stable control are 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 enhanced maneuverability improves access to difficult anatomical regions and supports more efficient surgical workflow during decompression procedures. The instrument incorporates a Panther-style cutting configuration , known for its smooth cutting action, dependable performance, and efficient tissue resection capabilities. This design enables controlled bone removal while maintaining excellent tactile feedback and surgical precision. With an 8-inch (200mm) shaft length , the instrument provides extended reach for deep operative fields encountered in cervical, thoracic, and lumbar spine surgery. The longer shaft allows access to challenging anatomical locations while maintaining excellent control and visibility. The Kerrison shaft is particularly effective for laminectomy, laminotomy, spinal decompression, foraminotomy, spinal stenosis surgery, discectomy, cervical spine surgery, thoracic spine surgery, lumbar spine surgery, and neurosurgical procedures . It is commonly used for removing lamina, hypertrophic bone, ligamentum flavum, osteophytes, and other structures causing neural compression. Manufactured from premium surgical-grade stainless steel , the shaft offers exceptional durability, corrosion resistance, and long-term clinical reliability. Precision engineering ensures smooth cutting performance, dependable rotational operation, and consistent functionality through repeated sterilization cycles and routine surgical use. The polished surgical finish facilitates thorough cleaning and supports compatibility with standard hospital sterilization protocols. Fully reusable and autoclavable, the Rotating Kerrison Shaft, 8″ (200mm) Straight, 4mm, 40° Up, Panther 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 access, and professional-grade reliability for advanced spinal surgery.
