Abstract
A spinal epidural needle assembly has a spinal needle assembly insertable in an epidural needle assembly. The spinal needle assembly has a rotatable cam lever on its hub, which engages a resilient tongue formed from the hub. The spinal needle assembly is locked with the epidural assembly by pushing in the cam lever, which displaces the tongue inwardly into frictional contact with the epidural needle hub.
