A Dural Suturing Needle is a specialised neurosurgical needle designed for precise suturing of the dura mater — the tough, outermost membrane covering the brain and spinal cord. It features a fine, curved, or semicircular profile that enables delicate manipulation in restricted surgical spaces. Manufactured with high-strength stainless steel, the needle ensures smooth tissue penetration without tearing or causing unnecessary trauma. It is primarily used in neurosurgery, spinal surgery, and micro-suturing procedures where precision and safety are critical.

Q1. What is a Dural Suturing Needle?

A Dural Suturing Needle (DSN) is a micro-surgical needle used for suturing the dura mater in neurosurgical procedures.

Q2. What curvatures are commonly used?

3/8 Circle (3/8C) and 1/2 Circle (1/2C) are the most common.

Q3. Can it be reused?

Both Single-Use (SU) and Reusable (RU) types exist depending on the model.

Q4. Which sutures are compatible?

Typically Micro-Sutures (MS) such as 4-0, 5-0, or 6-0.

Q5. Is it used in veterinary neurology?

Yes — it is widely used in Veterinary Neurosurgery (VNS) for dural repair.
