Abstract
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.
