IMPROVED NEEDLE

摘要

An improved needle for use in ultrasound guided techniques and administration of regional and/or local anaesthetic is described. The improved needle has a substantially cylindrical shaft having a proximal and distal end, with the distal end being cut substantially perpendicular to the longitudinal axis. In one embodiment the improved needle is provided with an internal protrusion which deflects the path of a catheter inserted through the needle. A further embodiment is provided with wings which can be attached to a support member provided with the needle in alternative first and second directions. A further embodiment is provided with a blinder which protrudes at the distal end of the needle and is designed to assist puncturing of the tissue. Embodiments of the improved needle which are echogenically enhanced and a needle assembly are also described.
