spinal introducer needle
A spinal introducer needle is a specialized medical device designed to facilitate safe and precise spinal procedures. This essential tool features a thin-walled, hollow tube with a precisely engineered tip that creates an initial pathway through tissue layers to access the spinal space. The needle is crafted from high-grade surgical steel, ensuring durability and maintaining structural integrity during procedures. Its design typically incorporates a beveled tip for optimal tissue separation and minimal trauma, while the hollow core allows for smooth insertion of smaller spinal needles. Modern spinal introducer needles often include depth markings along the shaft, enabling healthcare providers to monitor insertion depth accurately. The needle's hub is engineered for secure grip and control, featuring ergonomic designs that enhance handling during delicate procedures. These devices come in various gauges and lengths to accommodate different patient anatomies and specific procedural requirements. The introducer needle serves as a crucial component in spinal anesthesia, diagnostic procedures, and therapeutic interventions, providing a stable channel while protecting more delicate spinal needles from deflection or damage during insertion.
