A spinal needle is a specialized medical device used in spinal anesthesia and diagnostic lumbar puncture procedures. It is designed with a fine, sharp, and precise tip to safely penetrate the dura mater and access the spinal canal. Spinal needles are commonly made of high-quality stainless steel to ensure strength, flexibility, and corrosion resistance. They are available in various gauges and lengths to suit different patient needs and clinical requirements. The needle often includes a stylet to prevent tissue blockage during insertion. Spinal needles are widely used in surgeries for pain-free procedures and in collecting cerebrospinal fluid for diagnostic purposes.
