ABSTRACT:
A needle assembly is able to collect a sample of biological material in a needle of the assembly. The needle assembly has a safety shield capable of being moved on the needle assembly to cover a sharp tip of the needle assembly. The shield can be locked in place over the sharp tip by a locking mechanism. The assembly further includes an obturator that can be inserted into the needle to remove the sample from the needle. A reset member, which in some embodiments is associated with the obturator, is capable of operatively engaging the locking mechanism to release the locking mechanism and allow the shield to be moved away from the sharp tip.
