Rotating Kerrison Shaft, 7″ (175mm) Bayonet, 5mm, 40° up Panther Coat, Requires 70-2390P Micro

Rotating Kerrison Shaft, 7″ (175mm) Bayonet, 5mm, 40° Up, Panther Coat – Requires 70-2390P Micro Handle is a professional-grade modular surgical instrument engineered for spinal decompression, neurosurgical procedures, and orthopedic bone resection. Designed as a shaft-only component within a modular Kerrison Rongeur system, this instrument must be paired with the compatible 70-2390P 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 and ligamentous tissue during decompression procedures. The larger bite profile enhances procedural efficiency by reducing the number of instrument activations required while maintaining precise control and accuracy around critical anatomical structures.

Its 40° upward-facing footplate is specifically designed to facilitate controlled bone resection beneath anatomical structures while providing a versatile working angle. This configuration improves access to the spinal canal, neural foramina, and other confined operative spaces, enabling effective decompression with enhanced visibility and precise instrument positioning.

The specialized bayonet design offsets the working tip from the handle, positioning the surgeon’s hand away from the direct line of sight. This significantly improves visualization of the operative field and is especially beneficial during microscopic, minimally invasive, and complex spinal procedures where unobstructed viewing is essential.

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

The instrument incorporates a premium Panther Coat finish, engineered to enhance surface durability, reduce glare under surgical lighting, improve wear resistance, and support smooth instrument operation. The specialized coating contributes to long-term performance and reliability in demanding surgical environments.

With a 7-inch (175mm) shaft length, the instrument provides an ideal balance between reach and control. The extended working length allows access to deeper surgical fields while maintaining excellent instrument stability and handling precision.

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 enables surgeons to perform decompression procedures confidently and accurately while minimizing unnecessary tissue disruption.

Manufactured from premium surgical-grade stainless steel with a specialized Panther-coated finish, 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.

Fully reusable and autoclavable, the Rotating Kerrison Shaft, 7″ (175mm) Bayonet, 5mm, 40° Up, Panther Coat is suitable for hospitals, spine centers, orthopedic departments, neurosurgical facilities, and teaching institutions worldwide.

Trusted by spine surgeons and neurosurgical specialists, this modular instrument component delivers efficient bone removal, enhanced visualization, and professional-grade performance for advanced spinal and neurosurgical procedures.

Specifications

Frequently Asked Questions

What is this Kerrison shaft used for?

It is used for efficient 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 larger amounts of bone and tissue to be removed with each activation, improving procedural efficiency while maintaining excellent 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 within confined surgical spaces.

What is the benefit of the Panther Coat finish?

The Panther Coat finish enhances durability, reduces reflective glare under operating room lighting, improves wear resistance, and supports smooth instrument performance throughout repeated clinical use.

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 adjustment of the cutting tip orientation 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 70-2390P Micro Handle to function as a complete Kerrison Rongeur.

Is the instrument reusable?

Yes. The Rotating Kerrison Shaft, 7″ (175mm) Bayonet, 5mm, 40° Up, Panther Coat is fully reusable, autoclavable, and designed to maintain precision, durability, and performance through repeated sterilization and long-term clinical use.
