ARRANGEMENT FOR CELL SAMPLING

摘要

The present invention relates to an arrangement for taking a sample of cells from a suspicious lesion or a tumour with the so called fine needle aspiration technique, which arrangement provides a good penetration of tumours, especially small and/or hard fibrous tumours, 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 tumour and by applying both a rotational and a longitudinal movement to the needle when the needle is positioned inside the tumour. The arrangement is further provided with heat generating means in order to apply a short pulse of heat to the needle in order to lower the risk for the tumour to spread.
