Abstract
An arrangement for taking a sample of cells from a suspicious lesion or a tumor with the so called fine needle aspiration technique, provides a good penetration of tumors, especially small and/or hard fibrous tumors, and in the meantime yielding an increased amount of cells in the sample, by applying a longitudinal movement to the needle when the needle is penetrating the tumor and by applying both a rotational and a longitudinal movement to the needle when the needle is positioned inside the tumor. The arrangement is further provided with heat generating elements in order to apply a short pulse of heat to the needle in order to lower the risk for the tumor to spread.
