pencil point spinal needle types
Pencil point spinal needles represent a significant advancement in medical technology, specifically designed for precise and atraumatic spinal procedures. These specialized needles feature a unique non-cutting tip that separates rather than cuts through the dural fibers, significantly reducing the risk of post-dural puncture headaches. The design includes a solid, conical tip with a side port for medication administration, allowing for smooth penetration through tissue layers while maintaining structural integrity. Modern pencil point spinal needles come in various gauges, typically ranging from 22G to 27G, with lengths suitable for different patient populations. The needles incorporate clear depth markings and transparent hubs for easy CSF visualization. They're manufactured using high-grade medical stainless steel, ensuring optimal strength and flexibility while maintaining patient safety. These needles are extensively used in various medical procedures, including spinal anesthesia, diagnostic lumbar punctures, and therapeutic interventions. The design also features ergonomic handles for enhanced control and precision during procedures, making them particularly valuable in both routine and complex spinal procedures.
