Spinal needle or lumbar puncture needle is a needle, provided with a stylet, for entering the spinal canal or cisterna magna, with a bore of at least 1 mm and 40mm or more in length. Spinal needles are used to inject analgesia and/or anaesthetic directly into the CSF usually at a point below the second lumbar vertebra. Spinal needles enter the cerebral spinal fluid (CSF) through the membranes surrounding the spinal cord.

Spinal needles (Lumbar puncture needles) vary in their design, usually regarding the tip geometry, but are fundamentally similar and usually come with a stylet and introducer needle. Larger spinal needles may not require an introducer.

Used for diagnostic sampling of cerebrospinal fluid and for the introduction of contrast medium for myelography.

They come in the following sizes:

18G, 20G,21G,22G,23G,24G,25G X 90mm
