The Rotating Kerrison Shaft 7″ Bayonet 3mm 90° Up Stainless Steel is a precision-engineered neurosurgical instrument developed to meet the demanding requirements of modern spinal and cranial microsurgery. Designed for surgeons performing delicate decompression procedures, this rotating Kerrison shaft delivers exceptional control, accuracy, and durability while providing excellent visibility in confined operative fields.

The instrument features a 7-inch (175mm) bayonet shaft, specifically designed to improve surgical visualization by positioning the handle away from the operative field. This offset configuration minimizes hand obstruction, allowing surgeons to maintain a clear view of the surgical site while performing precise bone removal. The bayonet design also enhances ergonomics, making the instrument easier to manipulate during lengthy and technically demanding procedures.

Equipped with a 3mm cutting jaw, this rotating Kerrison shaft offers an excellent balance between precision and cutting efficiency. The jaw size is well suited for controlled removal of lamina, small bone fragments, and hypertrophic bone during decompression procedures. Its precise cutting action allows surgeons to work safely around delicate neural structures while minimizing unnecessary trauma to surrounding tissues.

The 90° upward biting tip is engineered to improve access to difficult anatomical regions. This upward orientation allows surgeons to approach targeted bone structures from an optimal angle, particularly during cervical and lumbar spine surgery where instrument positioning is critical. The design promotes efficient decompression while maintaining excellent visibility and control throughout the procedure.

One of the key advantages of this instrument is its rotating shaft mechanism, which enables surgeons to rotate the cutting jaw without repositioning the entire instrument. This functionality improves workflow efficiency, allows easier access to multiple surgical angles, and reduces unnecessary hand movement during microsurgical procedures. The smooth rotation mechanism provides reliable operation and consistent jaw alignment throughout repeated use.

Manufactured from premium surgical-grade stainless steel, this Kerrison shaft offers exceptional resistance to corrosion, wear, and repeated sterilization. The robust construction ensures long-term durability while maintaining cutting precision and mechanical performance. It is designed to withstand the rigorous demands of hospital operating rooms, neurosurgical departments, and specialized spine surgery centres.

This rotating Kerrison shaft is specifically designed for compatibility with the 70-2390 Micro system, ensuring secure attachment and dependable performance during advanced microsurgical procedures. Precision manufacturing guarantees consistent functionality, allowing surgeons to perform complex procedures with confidence.

Common clinical applications include laminectomy, spinal decompression, cervical decompression, lumbar decompression, microdiscectomy, foraminotomy, cranial bone removal, and other neurosurgical procedures requiring controlled bone excision. The instrument is particularly valuable when working within narrow operative corridors where precise bone removal is essential.

The ergonomic bayonet configuration improves surgeon comfort and reduces fatigue during extended procedures. Its reusable design supports long-term cost efficiency while maintaining consistent performance when cleaned, inspected, and sterilized according to standard medical protocols.

The Neurosurgery Surgical Rotating Kerrison Shaft 7″ Bayonet 3mm 90° Up Stainless Steel combines precision engineering, durable construction, and advanced microsurgical functionality, making it an indispensable instrument for neurosurgeons and spine surgeons performing complex decompression procedures.
