The invention refers to a puncturing device for generating a puncturing wound by means of a replaceable lancet that comprises a coupling element for transmitting a torque, whereby the puncturing device comprises a lancet drive which, for a puncture, transmits a torque to an inserted lancet that is coupled to the lancet drive by means of its coupling element such that the inserted lancet performs a puncturing motion in the form of a rotational motion about a geometric axis. According to embodiments of the invention, the geometric axis extends through the coupling element. The invention also refers to a lancet supply ribbon comprising lancets for such device and lancets comprising a lancet body having a lancet tip, whereby the lancet body, for coupling to a lancet drive of a puncturing device, comprises a coupling element by means of which the lancet can be made to perform a rotational motion and has a test field for assaying a body fluid sample to which a body fluid sample can be supplied only after the lancet tip has been pulled out of a puncturing wound that has been generated.
