Abstract:
1. A self-contained hand-held biopsy device for acquiring at least one tissue sample from a body of a living being, comprising: a hollow needle having a distal end portion with a circumferential cutting edge configured to sever a tissue sample from body tissue; a sample-receiving device received in the hollow needle, the sample-receiving device having a cavity configured to receive the tissue sample, the sample-receiving device being configured to move in the hollow needle between a first extended position and a second retracted position; a transport device coupled to the sample-receiving device, the transport device being configured to move the sample-receiving device relative to the hollow needle; and a liquid supply unit configured to carry and supply a flushing liquid, the liquid supply unit being configured to operatively connect to the cavity of the sample-receiving device when the sample-receiving device is in the second retracted position and is configured to deliver a lateral flow of the flushing liquid to the cavity to facilitate a lateral tissue sample ejection from the cavity, and wherein the liquid supply unit is disconnected from the cavity of the sample-receiving device when the sample-receiving device is in the first extended position.
