whitacre needle lumbar puncture
The Whitacre needle is a specialized medical device designed for performing lumbar punctures with enhanced safety and precision. This pencil-point spinal needle features a unique design with a closed, pencil-point tip and a side port for fluid collection. Unlike traditional Quincke needles, the Whitacre needle's distinctive tip configuration reduces the incidence of post-dural puncture headaches by minimizing trauma to the dural fibers. The needle separates rather than cuts through tissue layers, allowing for better healing and reduced complications. The side port location optimizes cerebrospinal fluid flow while maintaining structural integrity. Available in various gauge sizes, typically ranging from 22G to 27G, the Whitacre needle accommodates different clinical requirements and patient needs. The needle's construction typically involves high-grade stainless steel, ensuring durability and reliable performance during procedures. Medical professionals particularly value this needle for its improved safety profile in diagnostic and therapeutic procedures, including spinal anesthesia and cerebrospinal fluid collection. The design also incorporates clear depth markings and a comfortable hub for precise handling and optimal control during insertion.
