Abstract
A bone marrow needle has a cannula (12) connected to a cannula handle portion (18) extending equal distances from the axis of the cannula bore. A stylet (14) is slidably positioned into the cannula with its stylet handle (16) matingly receiving the proximal projections (18.4, 18.5) of the cannula handle portion into recess (16.6), thus preventing relative rotational movement of the cannula and stylus during use. Proximal projections (18.4, 18.5) define a space therebetween for a syringe connector (12.3) that enables aspiration through the cannula after insertion into the bone.
