Abstract
A biopsy device for harvesting at least one tissue sample from a human or animal body, e.g. in percutaneous aspiration biopsy, includes a hollow needle with a distal end portion adapted to be introduced into the body. A sample-receiving device with a cavity is movable in the hollow needle between a first extended and a second retracted position. A liquid supply unit comprising a flushing liquid, such as saline, is provided for ejecting the sample from the cavity, when the sample-receiving device is in the second retracted position. The liquid is conveyed form the liquid supply unit to a flushing chamber by an appropriate pump, such as a peristaltic pump.
