epidural anaesthesia needle
An epidural anaesthesia needle is a specialized medical device designed for precise administration of anesthetic medications into the epidural space of the spine. This highly engineered instrument features a hollow bore needle with a distinctive curved tip, typically ranging from 16 to 18 gauge in size. The needle incorporates advanced safety features, including depth markings for accurate placement and a specialized Tuohy tip that helps guide the catheter while minimizing tissue trauma. Modern epidural needles are crafted from surgical-grade stainless steel, ensuring durability and biocompatibility. The needle's design includes a tight-fitting stylet that prevents tissue coring during insertion and a transparent hub that allows for immediate visualization of cerebrospinal fluid. The device is engineered with exact specifications to enable smooth catheter threading and optimal drug delivery while maintaining patient safety. These needles are extensively used in obstetric anesthesia, pain management procedures, and surgical operations requiring regional anesthesia. The design incorporates ergonomic features for enhanced physician control and includes clear calibration markers for precise depth measurement. Advanced models may include echogenic properties for ultrasound guidance, further improving placement accuracy and patient outcomes.
