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 tissue to be biopsied and the cannula to be subsequently urged over the needle to collect the tissue.
