Abstract
A device for taking tissue samples by means of a biopsy cannula comprising a needle element with a cavity in its distal terminal zone and an exterior tube surround the needle element, which cannula is inserted into the tissue to be sampled by means of an inserting unit. The inserting unit causes the needle element and the exterior tube to move together into a position inside the tissue in which the exterior tube is pushed over the cavity, the inserting unit retracts the exterior tube behind the cavity in the needle element after termination of the inserting operation, and subsequently pushes the exterior tube again over the needle element so as to cover the cavity.
