Zusammenfassung:An apparatus for use with a biopsy device to position a needle of the biopsy device within breast tissue is described and claimed. The apparatus includes a cannula, an obturator; and an obturator actuation assembly, which is described as an "overshoot obturator". The overshoot obturator is designed to give the physician the ability to set the z-lock to the targeted depth, then move the obturator forward, relative to the sleeve to cut additional tissue. This reduces the tissue force which can push the obturator out of the desired biopsy location.
