<p>A biopsy instrument (40) includes a handle (1), and a disposable biopsy needle set or needle cartridge (20). The needle set includes a cannula (9) with a cannula hub (8), and a stylet (7) with a stylet hub (6). The needle set (20) is positionable within the handle (1), and actuatable thereby for purposes of taking a biopsy tissue sample. The needle set (20) and in particular the hubs (6, 8) in combination with the handle (1), perform the actuation sequence which allows the needle to be projected into the biopsy tissue, and the cannula to be subsequently urged over the needle to collect the tissue.</p> |
