Abstract
A biopsy probe mechanism includes an elongate sample receiving member having a longitudinal axis and a sample receiving notch. A cutting cannula is arranged coaxially with the elongate sample receiving member. The elongate sample receiving member and the cutting cannula are movable relative to one another along the longitudinal axis between a first relative position and a second relative position. A plurality of echogenic features include a first echogenic feature established on the elongate sample receiving member and a second echogenic feature established on the cutting cannula. The first echogenic feature is in longitudinal alignment with the second echogenic feature when the elongate sample receiving member and the cutting cannula are in the first relative position. The first echogenic feature is out of longitudinal alignment with the second echogenic feature when the elongate sample receiving member and the cutting cannula are in the second relative position.
