Dura mater knife

A dura mater knife is a hand-held surgical instrument used to cut or incise the dura mater — the tough outer membrane covering the brain and spinal cord — during neurosurgical procedures. Its design features a small, sharp, single-edged blade with a hooked distal end, allowing precise cutting while minimizing risk to underlying neural tissues.

This device is typically a reusable, one-piece instrument made of high-grade stainless steel, with a long slender shaft and a handle for manual control. As a reusable surgical tool, it is subject to cleaning, sterilization, and maintenance protocols in accordance with standard medical device regulations for reusable instruments.
