A simple, inexpensive device for aspiration biopsy

A simple, inexpensive aspiration device for biopsy has been described. It can be assembled quickly from readily available parts. It was primarily intended for fine needle aspiration biopsy of the thyroid gland, but it has been successfully used in our institution for computed tomography guided pulmonary biopsy as well. In addition, it can be conveniently used with a Menghini or Jamshidi needle for aspiration biopsy of other tissues. Finally, since the syringe plunger throw is adjustable, the device can be used in a clinical laboratory for the repeated sampling of identical aliquots of fluid.
