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.

Biopsy probe mechanism having multiple echogenic features

A biopsy probe mechanism and method includes an elongate sample receiving member having a longitudinal axis and having a sample receiving notch. The elongate sample receiving member and a cutting cannula are movable relative to one another along a longitudinal axis. A first echogenic feature and a third echogenic feature are established on the elongate sample receiving member and a second echogenic feature and a fourth echogenic feature are established on the cutting cannula. The elongate sample receiving member and the cutting cannula have a first position in which the first echogenic feature is in longitudinal alignment with the second echogenic feature, and in which the third echogenic feature is in longitudinal alignment with the fourth echogenic feature.

A biopsy probe mechanism includes an elongate sample receiving member having a longitudinal axis and having a sample receiving notch. The elongate sample receiving member and a cutting cannula are movable relative to one another along a longitudinal axis. A first echogenic feature is established on the elongate sample receiving member and a second echogenic feature is established on the cutting cannula. The elongate sample receiving member and the cutting cannula are configured to have a first position in which the first echogenic feature is in longitudinal alignment with the second echogenic feature, and configured such that when the elongate sample receiving member and the cutting cannula are moved relative to one another from the first position, the first echogenic feature and the second echogenic feature are out of longitudinal alignment.
