A sterile, sharp bevel-edged, hollow tubular metal instrument designed to obtain a specimen of bone marrow percutaneously. The device is typically available in a variety of large bores, and is sufficiently robust to penetrate bone (usually the hip bone or posterior iliac crest) with the force of pressure and twisting manually applied to its proximal handgrip. The resultant specimen is typically used for the pathological analysis of the source of blood cellular elements. This is a single-use device that has previously been used on a patient and has been subjected to additional processing and manufacturing for an additional single-use patient application.
