Fine needle arrangement for taking a sample of cells from suspicious lesions by using fine needle aspiration (FNA) technique, comprising a tubular needle member (1), a storage compartment (2) enclosing a chamber, and a coupling (3) to which a connector may be attached. At least a part (8) of the surface of the needle member has a rougher surface compared to the rest of the needle member surface in order to increase the acoustic reflection of the needle. |
