Toennis Dura Knife 19cm

Clinical Application

Designed for controlled sharp incision of the dura mater during neurosurgical procedures. The instrument is intended for precise opening of the dura in cranial and spinal approaches where a narrow, sharp cutting profile and tactile feedback are required—for example, dural windows, durotomy during tumor resection, cerebrospinal fluid access, and spinal decompression procedures.

Design & Configuration

The long 19 cm overall length provides reach into deeper operative fields while keeping the surgeon's hand clear of the surgical site. A straight, slender shaft and a fine cutting edge concentrate force on a small contact area to enable controlled initial penetration and predictable extension of the incision. This geometry reduces the need for repeated passes and helps minimize trauma to adjacent neural and vascular structures.
