Yasargil Arachnoid Knife

Description

Yasargil Arachnoid Knife

The Yasargil arachnoid knife is a microsurgical knife for opening the arachnoid, the thin membrane over the brain. Surgeons use it under the microscope to open cisterns and free vessels and nerves.

A knife for fine membranes

The arachnoid is thin and lies close to delicate structures. Therefore, the surgeon needs a small, controlled cutting tip. The Yasargil arachnoid knife gives that control during microsurgical dissection.

Curved down

We sell this knife at 18 cm with a tip that curves down. The downward curve lets the surgeon hook and cut membranes while keeping the tip in view. Also, the 18 cm length suits deep microsurgical work.

Where it fits

A microneurosurgery set combines knives, dissectors, micro scissors and micro forceps. The arachnoid knife starts openings in membranes, then micro scissors extend them. As a result, many surgeons keep it within easy reach.

Choosing a microsurgical knife

If you already use Yasargil dissectors, this knife completes the set. However, if you need a different tip angle, contact us before ordering. We can check which patterns we have available.

Caring for your arachnoid knife

Protect the fine tip at every stage. First, rinse it gently after the case. Next, clean it with a soft cloth rather than a stiff brush. Then dry it and sterilize it in a padded micro tray.

Ordering the Yasargil arachnoid knife

If this knife develops a defect in workmanship, a three-year warranty covers it. Before shipping, someone in Atlanta checks the tip under magnification by hand. Our FAQ page covers order basics. For micro knives we reference ASTM F899, the surgical instrument steel standard. To extend the cut, consider the Toennis-Adson scissors. See other micro tools in the neurosurgery category page.

Please note: this knife suits professional users only. A short care resource explains why micro instruments can look different on screen and where nickel fits in; returns follow our return policy.
