Spinal needle, single-use

Definition

A sharp bevel-edged, hollow tubular instrument designed for short-term use to withdraw a sample of cerebrospinal fluid (CSF), assist introduction of a spinal guidewire or catheter (e.g., lumboperitoneal shunt, intrathecal catheter), and/or deliver contrast media and/or anaesthetic or analgesic agents intrathecally (subarachnoid) or into a vertebral disc, either directly or using the needle-through-needle technique. It is typically fenestrated, spring-tipped, and made of metal and/or plastic materials; some types may be semi-rigid and include a stylet for support during handling. This is a single-use device.
