Spinal Needles Needles for Spinal Anesthesia With Introducer

Sold by HISWAY SURGICALS · Dansoman

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. An introducer needle is used in some cases to stabilise the insertion of the needle and aid insertion through tough skin. The needle and stylet are advanced towards the dura in the intevertebral space (the stylet stops tissue blocking the needle during insertion). An introducer needle is used in some cases to stabilise the insertion of the needle. Once through the dura and in position, the introducer is removed and the removal of the stylet enables CSF to flow into the needle hub.
