The combination needle is intended for peripheral nerve block. It comprises a plastic cannula (1) and an essentially cylindrical, solid steel mandrel (10), which is provided with a pricking tip, which is free from a cutting edge, and with a grip part (11), which has an electric plug contact (21) for the connection of an electrostimulator. The steel mandrel (10) can be introduced into the cannula (1) such that its pricking tip (42) protrudes from the front end of the cannula or is at least flush with same. It shall be achieved with the present invention that the two ["bei der die beiden" in German original should read "die beiden"-Tr.Ed.] electrodes necessary for the electrostimulation are located at a very short distance from one another and the electric effects of the stimulation is [sic-Tr.Ed.] limited to the body area where the stimulation shall take place. The steel mandrel (10) therefore has a two-pole design and is provided with a two-pole electric plug contact means (21, 37).
