Penfield Dura Dissector 29cm Fig.5

Clinical Application

Designed for delicate neurosurgical maneuvers, this instrument is used primarily for blunt dissection and controlled elevation of dura mater. It facilitates creation of dural flaps, separation of dura from underlying cortex or bone edges, and gentle mobilization of tissues in confined intracranial or spinal corridors under the operating microscope. The broad tip distributes contact pressure to reduce focal trauma when operating adjacent to neural tissue.

Design & Configuration

The flat, spatula-style tip and tapered profile provide a combination of surface area and a thin leading edge that enables both tissue separation and precise levering actions. The 29 cm shaft length offers extended reach for deeper cranial base and posterior fossa exposures while maintaining tactile feedback for controlled blunt dissection. The blunt, rounded tip geometry minimizes risk of cortical perforation and allows the surgeon to sweep and elevate dura in a gentle, atraumatic fashion.
