The Neurosurgery Rotating Kerrison Shaft 6″ Bayonet 2mm 40° Up is a precision-engineered modular neurosurgical instrument developed for meticulous bone removal during advanced spinal, cranial, and microsurgical procedures. Specifically designed for use with the 70-2390 Micro Handle, this detachable rotating shaft combines outstanding cutting precision, ergonomic handling, and long-lasting durability to meet the demanding standards of modern neurosurgery. It is an essential instrument for neurosurgeons and spine specialists performing delicate decompression procedures where precise bone excision is required while protecting surrounding neural and vascular structures.
The instrument features a 6-inch (150mm) Bayonet shaft, providing excellent maneuverability and superior visualization within deep and narrow surgical corridors. The Bayonet profile offsets the surgeon’s hand away from the operative field, creating an unobstructed view when working under an operating microscope or high-magnification surgical loupes. This ergonomic configuration improves surgical precision, enhances comfort during prolonged procedures, and allows accurate instrument positioning in confined anatomical spaces commonly encountered during spinal and cranial surgery.
Equipped with a 2mm footplate, this Kerrison shaft is designed for highly controlled bone removal in delicate operative environments. The narrow bite size enables surgeons to remove small portions of cortical and cancellous bone with exceptional precision, making it particularly suitable for microsurgical decompression where preservation of surrounding anatomy is essential. The 2mm bite offers outstanding tactile feedback and allows gradual enlargement of the surgical window while minimizing unnecessary bone removal.
The 40° up-biting jaw provides a controlled upward cutting angle that allows efficient access beneath the lamina and adjacent bony structures. Compared with a steeper jaw configuration, the 40° angle offers a more gradual approach to bone excision, improving visibility and facilitating smooth instrument movement within restricted operative fields. This design is especially effective during laminectomy, laminotomy, foraminotomy, and minimally invasive spinal procedures where accurate decompression is required while minimizing tissue manipulation.
One of the defining features of this instrument is its 360° rotating shaft mechanism, allowing the cutting tip to rotate freely while the handle remains stationary. This rotating capability enables precise orientation of the jaw without repositioning the surgeon’s hand, improving ergonomics and allowing easier access to difficult anatomical angles. The rotating mechanism reduces wrist fatigue during lengthy procedures and enhances overall surgical efficiency by providing continuous control throughout bone removal.
Manufactured from premium surgical-grade stainless steel, the Rotating Kerrison Shaft delivers outstanding mechanical strength, corrosion resistance, and long-term clinical reliability. Precision machining ensures smooth rotational movement, accurate jaw alignment, and consistent cutting performance throughout repeated surgical use. The polished stainless steel finish supports easy cleaning and complies with modern hospital sterilization and infection control protocols.
The shaft is specifically engineered for compatibility with the 70-2390 Micro Handle, providing a secure modular locking mechanism that enables rapid attachment and removal during surgery. The interchangeable modular design allows surgeons to utilize multiple shaft lengths, bite sizes, and jaw configurations using a single handle, improving operating room efficiency while reducing instrument inventory requirements.
The Neurosurgery Surgical Rotating Kerrison Shaft is widely used during laminectomy, laminotomy, spinal decompression, cervical spine surgery, thoracic spine surgery, lumbar spine surgery, foraminotomy, microdiscectomy, minimally invasive spine surgery, cranial bone removal, and skull base procedures. The 2mm, 40° up-biting jaw provides exceptional precision for controlled decompression while protecting adjacent neurological and soft tissue structures.
As a reusable surgical instrument, the Rotating Kerrison Shaft is fully compatible with standard hospital sterilization methods, including steam autoclaving. Its premium stainless steel construction ensures dependable long-term performance while maintaining cutting precision, smooth mechanical function, and structural integrity after repeated cleaning and sterilization cycles.
The Neurosurgery Surgical Rotating Kerrison Shaft, 6″ (150mm) Bayonet, 2mm, 40° Up, Stainless Steel, Requires 70-2390 Micro combines precision engineering, ergonomic Bayonet design, modular compatibility, and exceptional cutting accuracy. It is a trusted instrument for neurosurgeons and spine surgeons seeking reliable performance during advanced spinal and cranial procedures.
