Description
The BD Spinal Needle (405184) is a precision-engineered 18-gauge Quincke cutting-point needle intended for lumbar puncture and spinal anesthesia. The sharp Quincke bevel is designed to cut the dura mater efficiently, delivering excellent tactile feedback and facilitating accurate placement.
A translucent pink Luer hub provides a clear window for visual confirmation of cerebrospinal fluid (CSF) flashback, confirming correct needle positioning. The matched-ground bevel of the stylet and cannula helps minimize tissue coring and supports reliable performance during diagnostic and anesthetic procedures.
