The Rotating Kerrison Shaft 7″ Bayonet 1mm 90° Up Stainless Steel is a premium neurosurgical instrument developed to deliver exceptional precision during microsurgical spinal and cranial procedures. Designed for surgeons performing delicate decompression techniques, this rotating Kerrison shaft combines advanced engineering with ergonomic functionality to provide superior accuracy, control, and reliability. It is specifically manufactured for use with the 70-2390 Micro system, ensuring seamless integration into professional microsurgical instrument sets.

The instrument features a 7-inch (175mm) bayonet shaft, providing enhanced visibility during surgery by offsetting the handle from the working tip. This design allows surgeons to maintain a clear line of sight while working through surgical microscopes or magnification systems. The bayonet profile also minimizes hand obstruction within the operative field, making it particularly valuable during deep spinal and cranial procedures where visibility and precision are essential.

Equipped with a 1mm biting jaw, this rotating Kerrison shaft is designed for the most delicate bone removal applications. The ultra-fine jaw enables surgeons to perform highly controlled excision of lamina, osteophytes, and small bony structures while preserving surrounding neural tissues. The precision-machined cutting edges provide smooth, accurate cutting performance, making this instrument ideal for microsurgical decompression procedures requiring meticulous bone removal.

The 90° upward biting tip offers superior access to difficult anatomical structures. This configuration allows surgeons to approach bone from an optimal angle, improving visualization and facilitating precise decompression in confined operative spaces. The upward-facing jaw is particularly advantageous during cervical and lumbar spine surgery, where controlled access to superior anatomical structures is required.

A key feature of this instrument is its rotating shaft mechanism, which enables smooth adjustment of the cutting jaw without repositioning the entire instrument. This advanced functionality allows surgeons to rotate the jaw to the desired orientation quickly and efficiently, improving workflow while maintaining consistent cutting precision. The rotating mechanism enhances flexibility during complex microsurgical procedures and supports greater surgical efficiency.

Manufactured from premium surgical-grade stainless steel, this Kerrison shaft provides excellent corrosion resistance, mechanical strength, and long-term durability. The high-quality stainless steel construction withstands repeated autoclave sterilization and routine hospital reprocessing while maintaining precise jaw alignment and reliable cutting performance. This ensures dependable operation throughout years of clinical use.

Specifically designed to work with the 70-2390 Micro system, the instrument provides a secure connection and dependable performance during advanced neurosurgical procedures. Precision engineering ensures smooth articulation and consistent functionality, making it a trusted instrument for hospitals, spine centres, and neurosurgical operating theatres.

The Neurosurgery Surgical Rotating Kerrison Shaft is widely used during microdiscectomy, spinal decompression, laminectomy, laminotomy, cervical spine surgery, lumbar spine surgery, foraminotomy, and cranial microsurgical procedures. The fine 1mm jaw makes it particularly suitable for procedures requiring minimal bone removal and maximum preservation of surrounding anatomical structures.

Its ergonomic bayonet design reduces surgeon fatigue while improving comfort during extended procedures. As a reusable surgical instrument, it offers excellent long-term value when maintained according to established cleaning and sterilization protocols.

The Neurosurgery Surgical Rotating Kerrison Shaft 7″ Bayonet 1mm 90° Up Stainless Steel is an essential instrument for neurosurgeons seeking exceptional precision, durability, and performance in modern microsurgical practice.
