Abstract: A biopsy system includes a biopsy gun and a biopsy needle, the latter of which has an inner needle, also called a mandrel, and an outer tube, also called a cannula. The mandrel has a recess in the vicinity of its distal end which receives the tissue sample to be collected and has a first collecting element at its proximal end for connection with a slide of the biopsy gun. The cannula also has a connecting element at its proximal end for connection with another slide of the biopsy gun. The connecting elements each have an opening into which a pin provided on each of the respective slides can be inserted. In addition, at least one slide has a rib that extends in the lengthwise direction of the biopsy needle, the rib engaging a corresponding connecting element.
