Toennis Dura Knife 13cm

Clinical Application

Designed for controlled dural incisions, this precision knife is used to open and fashion the dura mater during cranial and selected spinal procedures. The instrument's compact length and refined cutting geometry facilitate delicate dissection in confined operative corridors, enabling accurate entry into the subdural space while minimizing collateral tissue trauma. It is appropriate for neurosurgeons and surgical teams performing craniotomy, decompression, and other procedures that require a reliable, fine cutting instrument for the dura.

Design & Configuration

The 13 cm overall length provides a balance between reach and tactile control—long enough to access deeper exposures while remaining short enough for precise, one-handed handling. The handheld form factor supports controlled linear incisions and fine directional changes common in dural work. A compact profile reduces obstruction of the surgical field and improves visualization when working through small craniotomy windows or retractor systems.
