An automatic biopsy instrument includes a cannula 13 provided over a stylet 11. The stylet 11 directs the cannular 13 to a biopsy site. The instrument urges the cannula 13 past the stylet 11 in order to collect a tissue sample and simultaneously causes a vacuum to be communicated to said cannular 13 in order to assist the collection of the tissue sample by the cannula 13.
