Abstract
A biopsy syringe for removing a specimen from a subject includes a tubular housing having a long hollow needle and two pistons. The first piston carries a mandrel received in the hollow needle. The second piston defines a chamber between it and the first piston enabling the syringe to be pre-loaded with a vacuum which is manually controllable so as to permit the first piston to be actuated to a retracted position in a smooth and simple manner while holding the biopsy syringe.
