Which instrument is used to elevate the dura off the cranial bone during a craniotomy?

The Woodson is specifically designed for the delicate task of separating or elevating the dura mater from the cranial bone during a craniotomy. This instrument typically features a spatula-like tip that allows for gentle manipulation of the dura without damaging it, which is crucial in neurosurgical procedures. The curved design and shallow profile facilitate adequate lifting and retraction, ensuring that the surgical field is visible and allowing for safe access to the underlying structures of the brain.

In contrast, scalpels are primarily for cutting tissue rather than elevating or retracting layers. Forceps are generally used for grasping and holding tissues, and clamps are designed for occlusion or securing vessels, making them unsuitable for the specific requirement of elevating the dura. Thus, the Woodson is the appropriate instrument for this task in a craniotomy setup.
