The invention relates to a needle for applying neuraxial anaesthesia, where said needle can act as both a spinal needle and an epidural needle, comprising: a first handle (6) holding a first cannula (7), said first handle (6) being covered, on the free end thereof, by a mandrel (8), such that the first handle (6) comprises, in an upper central part, a semi-spherical magnifying glass (9) which amplifies the field of vision, allowing the detection of the outflow of cerebrospinal liquid at a higher resolution, and a rear part of the mandrel (8) has a rounded shape so as to allow a better fit in the hand, and a slight upward incline to allow the user to pick the needle (1) up from a working table with just one hand. The ergonomic structure allows the needle to be guided with absolute precision and orientation over the puncture zone of the patient. Fins can also be coupled to the needle so as to allow the use thereof as an epidural needle.
