The 8″ Panther Rotating Kerrison Shaft 4mm 40° Up combines an 8-inch overall length with a 4 mm bite and straight configuration.
Its defined working profile is intended for precise laminar and foraminal access in neurosurgical applications.

Design & Function

The Panther Rotating Kerrison Shaft features a straight working configuration designed to provide a specialized orientation during microsurgical procedures. The 40° upward angle can assist in positioning the working end according to the requirements of the operative field.

The 4 mm bite provides a defined cutting profile, while the 8-inch overall length allows controlled manual positioning. Together, these dimensions provide a practical configuration for neurosurgical procedures requiring a straight instrument type.

Surgical Applications

The 8″ Panther Rotating Kerrison Shaft 4mm 40° Up may be used for neurosurgical and spine surgery applications involving precise access to laminar and foraminal structures. Specific use depends on the surgical procedure, technique, anatomical site, and preference of the clinical team.

Handling & Instrument Care

Inspect the rotating Kerrison shaft before use, paying particular attention to the working end and alignment. Ensure the instrument is properly aligned and free from visible damage or wear before use.

After use, clean and process the instrument according to the manufacturer's validated instructions and the healthcare facility's established instrument-processing protocols. Store the rotating Kerrison shaft appropriately to protect its working end and prevent unnecessary contact with other instruments.
