The Rotating Kerrison Shaft 7″ Bayonet 4mm 90° Up Stainless Steel is a specialized neurosurgical instrument engineered for precision, flexibility, and dependable performance during advanced microsurgical procedures. Designed for use in spinal and cranial surgery, this rotating Kerrison shaft provides surgeons with enhanced access and controlled bone removal capabilities in areas where accuracy and visualization are critical.

The instrument features a 7-inch (175mm) bayonet shaft configuration, which provides improved working clearance and a more ergonomic approach compared with traditional straight shaft instruments. The bayonet design offsets the working tip from the handle, helping maintain a clear surgical field and improving visibility during deep or narrow operative approaches. This makes the instrument highly suitable for procedures requiring precise manipulation around delicate neurological structures.

With a 4mm bite size, this Kerrison shaft provides efficient and controlled removal of bone fragments, lamina, and other hard tissues during decompression procedures. The carefully engineered jaw size offers a balance between effective cutting performance and surgical precision, making it suitable for a variety of neurosurgical applications where controlled tissue removal is required.

The 90° upward angled tip allows surgeons to access challenging anatomical regions with improved positioning and visualization. The upward-facing jaw orientation supports accurate cutting angles during spinal decompression and cranial procedures, helping surgeons perform precise maneuvers while maintaining better instrument control.

The integrated rotating shaft mechanism enhances operational flexibility by allowing adjustment of the cutting orientation during surgery. This feature reduces the need for repeated instrument repositioning and enables surgeons to achieve optimal working angles within restricted surgical spaces. The smooth rotational movement improves efficiency and supports consistent performance throughout complex procedures.

Manufactured from high-quality surgical-grade stainless steel, this rotating Kerrison shaft delivers excellent strength, corrosion resistance, and long-lasting durability. The stainless steel construction is designed to withstand repeated cleaning and sterilization cycles while preserving the instrument’s precision, alignment, and functional integrity. It is suitable for professional medical environments including hospitals, neurosurgical centres, and specialized operating rooms.

This instrument is specifically designed to require the 70-2390 Micro system, ensuring compatibility with advanced microsurgical setups. The secure attachment system provides stable performance and reliable operation during demanding surgical procedures.

The Neurosurgery Rotating Kerrison Shaft is commonly utilized in procedures including spinal decompression, cervical and lumbar laminectomy, microdiscectomy, spinal canal surgery, and cranial microsurgery. Its precision 4mm jaw design assists surgeons in achieving effective decompression while maintaining control around sensitive neural anatomy.

The ergonomic bayonet profile improves surgeon comfort by supporting better hand positioning and reducing obstruction in deep operative fields. Its reusable design provides long-term value when properly maintained through recommended cleaning, inspection, and sterilization protocols.

The Neurosurgery Surgical Rotating Kerrison Shaft 7″ Bayonet 4mm 90° Up Stainless Steel represents a combination of advanced surgical engineering, precision manufacturing, and reliable durability, making it an essential instrument for modern neurosurgical and spinal procedures.
