Abstract

An automatic control system for a vacuum-assisted automatic core biopsy device (10) is provided, wherein the automatic core biopsy device (10) comprises a housing (12), out of which extends a needle assembly (14) including a hollow outer piercing needle (16), an inner cutter (18) having a lumen (20), a probe housing (22), and a tissue receiving notch (24). The automatic control system (92) is computerized to move the hollow outer piercing needle (16) automatically to the target tissue lesion, as was true in the prior art, but also is programmed to automatically control the rotational orientation of the piercing needle (16), and its associated tissue receiving notch (24), as well as the axial positioning and rotation of the cutting cannula (18). Consequently, a clinician user need only mark the desired locations within the target location from which tissue samples are desired and the automatic control system will operate the device to retrieve samples from the marked locations.
