Spinal needles have several important characteristics:
Needle Type: These are Quincke-type spinal needles used for spinal anesthesia or lumbar puncture.
Sterility and Single Use: They are sterile and designed for single use only to prevent infection.
Material and Design:
The needle barrel is made of thin-walled steel, facilitating the reflux of cerebrospinal fluid (CSF).
The needle hub is transparent to allow rapid visualization of CSF or blood reflux.
A notch or lug on the hub can indicate the bevel orientation.
Style:
The stylet fits snugly into the needle lumen to prevent coring and minimize tissue damage.
Its hub is colored differently depending on the needle’s outer diameter (standardized color coding).
