Abstract
A bone needle assembly has a cannula and a stylet including a shaft received in a cannula shaft. A stylet safety shield is carried by the stylet to cover a sharp tip of the stylet shaft when removed from the cannula shaft after the bone is penetrated. The stylet includes a shield release device that moves the shield somewhat out of a handle member of the stylet when the stylet is released from the cannula, so that the safety shield can be more easily grasped.
