Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 4mm, 40° up, Stainless Steel, Requires 70-2390 Micro

Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 4mm, 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 paired with the compatible 70-2390 Micro Handle to create a complete and functional surgical instrument.

The shaft features a 4mm bite size, providing an ideal balance between efficient tissue removal and precise surgical control. This bite profile enables surgeons to remove substantial amounts of bone and ligamentous tissue while maintaining accuracy around delicate anatomical structures and neural elements.

Its 40° upward-facing footplate is specifically designed to facilitate controlled bone resection beneath anatomical structures while offering a more versatile working angle than traditional 90° configurations. The 40° up design enhances access to targeted surgical areas and supports precise decompression within the spinal canal and neural foramina.

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

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 improves maneuverability, facilitates access to difficult anatomical locations, and enhances efficiency during decompression procedures.

With a 6-inch (150mm) shaft length, the instrument provides excellent control and responsiveness while maintaining sufficient reach for a variety of spinal procedures. The compact length is especially beneficial when operating within confined surgical corridors that require precise instrument handling.

The Kerrison shaft is particularly effective for laminectomy, laminotomy, spinal decompression, foraminotomy, spinal stenosis surgery, cervical decompression, lumbar decompression, thoracic spine procedures, 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 allows surgeons to perform decompression procedures confidently while minimizing unnecessary disruption to surrounding tissues.

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, 4mm, 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 precise 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 4mm bite size provide?

The 4mm bite size offers an excellent balance between precision and efficiency, allowing surgeons to remove larger amounts of bone while maintaining accurate control during decompression procedures.

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 while maintaining optimal instrument positioning.

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 procedural 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, 4mm, 40° Up, Stainless Steel is fully reusable, autoclavable, and engineered to maintain precision, durability, and performance through repeated sterilization and long-term clinical use.
