Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 5mm, 40° up, Stainless Steel, Requires 70-2390 Micro

Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 5mm, 40° Up, Stainless Steel – Requires 70-2390 Micro Handle is a professional-grade modular surgical instrument engineered for spinal decompression, neurosurgery, and orthopedic bone resection procedures. Designed as a shaft-only component within a modular Kerrison Rongeur system, this instrument must be used with the compatible 70-2390 Micro Handle to create a complete and fully functional surgical instrument.

The shaft features a 5mm bite size, allowing surgeons to efficiently remove larger amounts of bone, ligamentous tissue, and compressive structures during decompression procedures. The wider bite profile enhances procedural efficiency by reducing the number of instrument activations required while maintaining excellent surgical control.

Its 40° upward-facing footplate is specifically designed to facilitate controlled bone resection beneath anatomical structures while providing a versatile working angle for targeted decompression. The 40° configuration improves access to the spinal canal, neural foramina, and other difficult-to-reach anatomical areas while maintaining precise instrument positioning.

The specialized bayonet design offsets the working tip from the handle, keeping the surgeon’s hand outside the direct line of sight. This significantly improves visualization of the operative field and is particularly advantageous during microscopic, minimally invasive, and complex spinal procedures where unobstructed visibility is essential.

A key feature of this instrument is its rotating shaft mechanism, which enables surgeons to adjust the orientation of the cutting tip without repositioning the entire instrument. This capability enhances maneuverability, improves access to challenging anatomical regions, and increases efficiency during decompression and bone resection procedures.

With a 6-inch (150mm) shaft length, the instrument provides an excellent balance between reach and control. The compact length offers superior responsiveness and precise handling, making it especially suitable for procedures performed within confined operative spaces.

The Kerrison shaft is particularly effective for laminectomy, laminotomy, spinal decompression, foraminotomy, spinal stenosis surgery, cervical decompression, lumbar decompression, thoracic spine surgery, and neurosurgical interventions. It is commonly used for removing lamina, osteophytes, ligamentum flavum, hypertrophic bone, and other structures contributing to neural compression.

The precision-engineered cutting mechanism delivers smooth and controlled bone resection while providing excellent tactile feedback. This enables surgeons to perform decompression procedures confidently and accurately 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, 6″ (150mm) Bayonet, 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 efficient bone removal, enhanced surgical visibility, and professional-grade clinical reliability for advanced spinal and neurosurgical procedures.

Specifications

Frequently Asked Questions

What is this Kerrison shaft used for?

It is used for controlled bone removal and spinal decompression during spine surgery, neurosurgery, and orthopedic procedures.

What advantage does the 5mm bite size provide?

The 5mm bite size allows efficient removal of larger amounts of bone and tissue, improving procedural efficiency while maintaining precise surgical control.

What is the purpose of the 40° upward footplate?

The 40° upward-facing footplate provides improved access to targeted anatomical structures and facilitates controlled decompression in confined surgical spaces.

Why is the bayonet design beneficial?

The bayonet configuration improves surgical visibility by keeping the surgeon’s hand outside the direct viewing path, providing a clearer and less obstructed view of the operative field.

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, 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, 6″ (150mm) Bayonet, 5mm, 40° Up, Stainless Steel is fully reusable, autoclavable, and engineered to maintain precision, durability, and performance through repeated sterilization and long-term clinical use.
