Embodiments of a needle biopsy device having a rotating needle mechanism to automatically cut sample tissue that can be operated remotely. A portable small biopsy robot can improve biopsy accuracy, reduce the pain and complications, and shorten the duration of the total biopsy time by using an automatic needle rotating mechanism and a needle localization system that allows a medical practitioner to perform the biopsy procedure from a remote distance. The needle biopsy device can include a cannula and a rotational biopsy needle with a blade the rotational biopsy needle axially and rotatably moveable within the cannula lumen, the blade configured to remove, cut, and/or separate a tissue sample from the target tissue site through rotation of the blade, and to hold the tissue sample in the rotational biopsy needle during proximal retraction from the patient.
