The device has a puncture cannula (2) tapering to a needle point, where proximal end of the puncture cannula is connected with a retrieving container for organic sample. A puncture area is formed in a connector in the needle point, and the puncture cannula runs in a flushing pipe. A flushing canal (13) is formed between an outer wall of the cannula and an inner wall of the flushing pipe. A distal end of the flushing canal has a transfer opening (14) in a vacuum channel (8) of the cannula. |
