The apparatus also includes a stylet 9 which is adapted to rest within the hollow needle such that the distal tip of the stylet 9 closes the piercing tip 2 of the needle 7. Also included is a method of use of the device, comprising the inserting the cannula 5 into a first puncture site, obtaining a first biopsy from a first site through the cannula 5, then changing the orientation of the cannula 5 within the first puncture site, with respect to the perineum and obtaining a biopsy from the second site.
