Feature & Benefit
Quincke (Cutting Tip): Features a sharp, beveled tip that cuts through tissue. It is often preferred for diagnostic lumbar punctures because it provides faster access and clear tactile feedback.
Pencil-Point (Atraumatic): Designs like Whitacre or Sprotte have a blunt, rounded tip that spreads tissue fibers rather than cutting them. This significantly reduces CSF leakage and the risk of postprocedure headaches.
