摘要： A core needle biopsy device includes a needle assembly, a drive assembly, and a user interface. The needle assembly includes a piercer and a hollow cutter. The piercer includes a sharp distal tip and a notch proximal to the distal tip. The piercer is slidably disposed within the cutter to sever a tissue sample into the notch of the piercer. The drive assembly is configured to selectively move the piercer and the cutter. The user interface has a plurality of indicators. Each indicator of the plurality of indicators is configured to independently transition between a plurality of predetermined states to collectively define a plurality of predetermined status sequences that indicate movement of the piercer and the cutter via the drive mechanism.
