Spinal Needle

1. Pencil point design (e.g., Whitacre or Sprotte) minimizes dural trauma and reduces the risk of post-dural puncture headache (PDPH) by separating dural fibers rather than cutting them. 2. Quincke type features a traditional cutting-bevel tip, which provides sharp penetration for easier insertion through the dura but may have a higher PDPH rate compared to pencil point needles. 3. Atraumatic and sharp tip options – Available in both pencil point (for reduced tissue disruption) and Quincke (for precise cutting), allowing clinicians to choose based on procedure requirements and patient risk factors.
