Method for obtaining tissue and cells by fine needle aspiration for cytology/biopsy and kit relating to the same

摘要

The method involves obtaining tissue and cells for biopsy by fine needle aspiration comprising the steps of: (a) inserting one end of a fine, hollow needle into an area of body tissue; (b) inserting the protruding end of the fine, hollow needle into an evacuated container with a pre-established vacuum; (c) continuously suctioning tissue and cell samples through the fine, hollow needle into the container; (d) withdrawing the fine, hollow needle from the body tissue; and (e) preserving the tissue and cell samples in the container. A tissue needle aspiration biopsy kit is also disclosed having component parts capable of being assembled to provide means for aspiration biopsy of soft body tissue and cells, kit comprising a combination of (a) at least one fine, hollow needle having one end adapted for insertion into a vacuum container and the other end adapted for introduction into an area of the body; (b) at least one evacuated container adapted to be affixed to the hollow needle with a pre-established vacuum sufficient so as to cause a suction of the tissue and cells through the fine, hollow needle into the container; and (c) a physiological solution to preserve the tissue and cell samples collected in the container.
