Abstract:
A pudendal/paracervical block anesthesia needle assembly is provided. The assembly includes a needle guide which limits the extent to which a needle may be inserted within a patient. The needle guide includes a housing to which a cannula is secured. A needle assembly including a needle hub and needle are insertable within the guide such that the needle is positioned within the cannula and the needle hub within the guide housing. The needle guide housing includes a recess including two pairs of parallel walls. A pair of abutments, one positioned distal to the other, extend within the recess. The needle hub includes a contact surface which contacts one of the two abutments depending upon its rotational position. The extent to which the needle projects outside the cannula is determined by which abutment is engaged by the contact surface of the hub.
