Rotating Kerrison Shaft, 7″ (175mm) Bayonet, 1mm, 40° up, Panther Coat, Requires 70-2390P Micro

Rotating Kerrison Shaft, 7″ (175mm) Bayonet, 1mm, 40° Up, Panther Coat – Requires 70-2390P Micro Handle is a professional-grade modular surgical instrument engineered for highly delicate spinal decompression, neurosurgical interventions, and orthopedic bone resection procedures. Designed as part of a modular Kerrison Rongeur system, this shaft must be paired with the compatible 70-2390P Micro Handle to create a complete and fully functional surgical instrument.

The shaft features an ultra-fine 1mm bite size, making it ideally suited for microsurgical applications requiring maximum precision. The small bite profile enables surgeons to remove minimal amounts of bone and ligamentous tissue while maintaining exceptional control around sensitive neural structures, including the spinal cord, nerve roots, and dura mater.

Its 40° upward-facing footplate provides improved access to anatomical structures located beneath bony surfaces while offering a versatile working angle for controlled decompression. The 40° configuration allows precise bone resection in confined surgical spaces and facilitates access to challenging anatomical regions within the spinal canal and neural foramina.

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

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 enhances maneuverability, improves access to difficult surgical targets, and increases procedural efficiency during intricate decompression 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 coated surface contributes to long-term performance and reliability in demanding surgical environments.

With a 7-inch (175mm) shaft length, the instrument offers an excellent balance between reach and control. The length is particularly suitable for cervical, thoracic, and lumbar spinal procedures requiring precise bone removal within deep but confined operative corridors.

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

The precision-engineered cutting mechanism provides smooth and controlled bone resection while delivering excellent tactile feedback. This enables surgeons to perform highly delicate 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 outstanding 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 instrument is fully reusable and autoclavable, making it suitable for hospitals, spine centers, orthopedic departments, neurosurgical facilities, and teaching institutions worldwide.

Trusted by spine surgeons and neurosurgical specialists, the Rotating Kerrison Shaft, 7″ (175mm) Bayonet, 1mm, 40° Up, Panther Coat delivers ultra-precise 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 ultra-precise bone removal and spinal decompression during spine surgery, neurosurgery, and orthopedic procedures involving delicate anatomical structures.

What advantage does the 1mm bite size provide?

The 1mm bite size allows extremely fine and controlled bone resection, making it ideal for microsurgical decompression procedures near critical neural tissues.

What is the benefit of the 40° upward footplate?

The 40° upward-facing footplate provides improved access to targeted anatomical structures while enabling controlled decompression and precise bone removal in confined surgical spaces.

What is the purpose of the Panther Coat finish?

The Panther Coat finish enhances durability, reduces reflective glare, 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 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, 1mm, 40° Up, Panther Coat is fully reusable, autoclavable, and designed to maintain precision, durability, and performance through repeated sterilization and long-term clinical use.
