Injection assembly for blocking peripheral nerves, for instance for plexus anaesthesia

摘要

An injection device is described for the blocking of peripheral nerves, e.g., for plexus anaesthesia. This injection device has an injection needle of metal which is provided at one end with a needle tip and at the opposite end with a base part for the connection of a syringe. In order in this injection device to largely eliminate the danger of damage to nerve fibers or injury to blood vessels by the injection needle and to permit an additional aid by the positive location of the plexus, the needle tip is formed by a ground surface inclined at an angle of 40. degree. to 60, preferably of 45 to 50, to the cannula axis.
