A sampling device includes a cannula (10) having a first end (13), and a second end (25). The first end (13) has a beveled tip (22), and a threaded section (16) with a projecting helical rib (19). The second end (25) include s a handle (28). The cannula (10) further includes an axial channel (34) extending between the first, and second ends. The axial channel is configure d to receive a variety of medical devices including an axial channel (34), a stylet (37) having a sharpened point (43), and a core collector (58) in a co re biopsy procedure. The core collector (58) has an axial cavity (67) extending between a first end (61), and a second end (64) of the core collector (58). The first end (61) of the core collector (58) includes one or more teeth (70 ) extending into the axial cavity (67). The second end (64) of the core collector (58) includes a haft (73), and a connector device (76) for connecting the core collector (58) to the cannula (10).
