ABSTRACT:
A needle guide is provided which includes a hub and a needle connected to the hub. A stylet may also be provided for insertion into the hollow interior of the needle to aid in the insertion of the needle through tissue. The needle has a transverse breaking section, preferably a groove, adjacent to the hub. The breaking section is configured so that the needle will break cleanly in two at the breaking section when the hub is bent back and forth relative to the portion of the needle distal to the breaking section. An alternative embodiment of the needle guide provides a handle which extends from the hub over the needle. A hinge is provided in alignment with the needle breaking section to permit the handle to be flexed relative to the hub when the hub is moved back and forth in the manner described.
