The Neurosurgery Rotating Kerrison Shaft 8″ Straight 4mm 40° Up Panther is a precision-engineered modular neurosurgical instrument developed for controlled bone removal during advanced spinal and cranial procedures. Specifically designed for use with the 70-2390P Micro Handle, this detachable rotating shaft provides exceptional surgical precision, ergonomic handling, and long-term durability. It is an essential instrument for neurosurgeons and spine surgeons performing delicate decompression procedures where controlled bone excision is critical for protecting adjacent neural structures.
With an overall length of 8 inches (200mm), this rotating Kerrison shaft provides extended reach into deep operative fields while maintaining excellent balance and maneuverability. The straight shaft configuration allows direct access to the operative site, making it ideal for cervical, thoracic, and lumbar spine procedures. Its elongated design enables surgeons to work comfortably within deep anatomical spaces while maintaining optimal visualization and precise control throughout the procedure.
The instrument features a 4mm footplate combined with a 40° up-biting jaw, providing an ideal balance of precision and cutting efficiency. The 4mm bite is particularly well suited for controlled removal of moderate amounts of cortical and cancellous bone while preserving surrounding anatomical structures. The 40° upward jaw angle facilitates access beneath the lamina and adjacent bony anatomy, allowing surgeons to perform decompression procedures with improved visibility and minimal disruption to surrounding soft tissue.
A major advantage of this instrument is its 360° rotating shaft mechanism, which allows the cutting jaw to be positioned at virtually any angle without repositioning the surgeon’s hand. This rotating capability improves ergonomics, enhances access within narrow surgical corridors, and allows more efficient bone removal in confined operative fields. The result is greater procedural flexibility and improved precision during complex spinal surgery.
This model features an advanced Panther-coated shaft, engineered to provide enhanced surface hardness, superior wear resistance, and reduced glare under operating room lighting. The low-reflective Panther finish improves visual comfort during microscope-assisted procedures while helping preserve the instrument’s appearance and functionality through repeated clinical use. The coating also contributes to increased corrosion resistance and extended instrument life.
Manufactured from premium surgical-grade stainless steel, the Rotating Kerrison Shaft offers outstanding strength, corrosion resistance, and mechanical reliability. Precision machining ensures consistent jaw alignment, smooth rotational movement, and dependable cutting performance during demanding surgical procedures. The robust construction maintains structural integrity through repeated sterilization cycles, making it suitable for continuous use in high-volume neurosurgical operating theatres.
The shaft is specifically designed as a Shaft Only configuration and requires the 70-2390P Micro Handle for operation. The secure modular locking system allows rapid attachment and removal, enabling surgeons to interchange shaft sizes and jaw configurations efficiently while using a single Panther Micro Handle. This modular approach improves operating room workflow and provides greater procedural versatility.
The Neurosurgery Surgical Rotating Kerrison Shaft is widely used during laminectomy, laminotomy, spinal decompression, cervical spine surgery, thoracic spine surgery, lumbar spine surgery, foraminotomy, discectomy, minimally invasive spinal surgery, cranial bone removal, and other neurosurgical procedures. The 4mm, 40° up-biting jaw provides exceptional versatility for precise bone excision while minimizing trauma to surrounding neurological structures.
As a reusable surgical instrument, this rotating Kerrison shaft is fully compatible with standard hospital sterilization methods, including steam autoclaving. The combination of premium stainless steel construction and Panther coating ensures reliable long-term performance while maintaining precise cutting efficiency after repeated cleaning and sterilization.
The Neurosurgery Surgical Rotating Kerrison Shaft, 8″ (200mm) Straight, 4mm, 40° Up, Panther – Shaft Only – Requires 70-2390P Micro combines advanced engineering, modular compatibility, ergonomic performance, and precision cutting capability. It is an indispensable instrument for neurosurgeons and spine specialists seeking dependable bone removal during complex spinal and cranial procedures.
