Patent ID: 7871383

Claim:
Fine needle aspiration arrangement for taking a cell sample from a suspicious human or animal tissue lesion or a tumor, comprising: a hollow needle ( 2 ), a longitudinal movement means ( 6 ) adapted to apply an oscillating longitudinal movement ( 10 ) to the needle ( 2 ), a rotational movement means ( 8 ) adapted to apply a rotational movement ( 12 ) to the needle ( 2 ), when the needle is positioned inside the cell sample site, and a pressure regulating means ( 14 ) adapted to create under pressure in the hollow part ( 20 ) of said needle for taking the cell sample, wherein said rotational movement ( 12 ) and said longitudinal movement ( 10 ) are maneuvered independent from each other and wherein said longitudinal movement ( 10 ) is in the range of 30-300 Hz, wherein said rotational movement ( 12 ) is adapted to be applied to the needle ( 2 ) while the needle is in the longitudinal movement ( 10 ), and wherein the hollow part ( 20 ) of the needle ( 2 ) is filled with a liquid that prevents unwanted tissue from entering the hollow part of the needle when the needle is inserted into the cell sample site and wherein the pressure regulating means ( 14 ) is adapted to apply reduced pressure to the hollow part ( 20 ) of said needle in order to remove the liquid from the needle ( 2 ).
