Rotating Kerrison Shaft, 8″ (200mm) Straight, 1.5mm, 40° Up Stainless Steel – Requires 70-2390 Micro

Rotating Kerrison Shaft, 8″ (200mm) Straight, 1.5mm, 40° Up Stainless Steel – Requires 70-2390 Micro Handle is a professional-grade modular surgical instrument engineered for highly precise spinal decompression, neurosurgery, and orthopedic procedures. 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 functional surgical instrument.

The shaft features a 1.5mm bite size, making it ideal for microsurgical and fine decompression procedures where controlled tissue removal and maximum precision are essential. The small bite profile allows surgeons to carefully remove bone and ligamentous tissue near critical neural structures while preserving surrounding anatomy.

Its 40° upward-facing footplate is specifically designed to facilitate controlled bone resection beneath overlying anatomical structures. This configuration provides improved access to confined surgical corridors and supports precise decompression of the spinal canal and neural foramina.

The straight shaft design offers direct instrument alignment and predictable handling characteristics. This configuration enables accurate instrument positioning and precise control during open 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 tip without repositioning the entire instrument. This enhanced maneuverability improves access to difficult anatomical locations and supports efficient decompression procedures in confined operative spaces.

With an 8-inch (200mm) shaft length, the instrument provides extended reach for deep surgical fields encountered during cervical, thoracic, and lumbar spine surgery. The longer shaft allows precise access to challenging anatomical regions while maintaining excellent control and visualization.

The Kerrison shaft is particularly effective for laminectomy, laminotomy, spinal decompression, foraminotomy, microdiscectomy, spinal stenosis surgery, cervical spine procedures, lumbar decompression, and neurosurgical interventions. Its precision cutting mechanism enables controlled removal of lamina, osteophytes, ligamentum flavum, and other structures contributing to neural compression.

The finely engineered cutting jaws provide smooth and accurate bone resection while delivering excellent tactile feedback. This allows surgeons to perform delicate decompression procedures with confidence, especially when operating near the spinal cord, dura, and nerve roots.

Manufactured from premium surgical-grade stainless steel, the shaft offers exceptional durability, corrosion resistance, and long-term clinical reliability. Precision manufacturing ensures smooth cutting action, dependable rotational performance, 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, 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 exceptional precision, enhanced surgical access, and professional-grade reliability for advanced spinal and neurosurgical procedures.

Specifications

Frequently Asked Questions

What is this Kerrison shaft used for?

It is used for delicate bone removal and spinal decompression during spine surgery, neurosurgery, and orthopedic procedures where high precision is required.

What advantage does the 1.5mm bite size provide?

The 1.5mm bite size allows extremely precise and controlled bone resection, making it ideal for microsurgical procedures and decompression near sensitive neural structures.

What is the purpose of the 40° upward footplate?

The 40° upward-facing footplate improves access beneath bony structures and facilitates controlled decompression within confined surgical spaces.

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 and surgical efficiency.

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, 8″ (200mm) Straight, 1.5mm, 40° Up Stainless Steel is fully reusable, autoclavable, and designed to maintain precision, durability, and performance through repeated sterilization and long-term clinical use.
