A method for operating a biopsy device to acquire at least one tissue sample from a body of a living being, including retracting a sample-receiving device through a hollow needle to a sample removal position, a tissue sample being simultaneously transported to the sample removal position by the sample-receiving device; operatively connecting a liquid supply unit to a cavity of the sample-receiving device when the sample-receiving device is at the sample removal position; and delivering a lateral flow of a flushing liquid from the liquid supply unit to the cavity of the sample-receiving device to facilitate a lateral tissue sample ejection from the cavity.
1. A method for operating a biopsy device to acquire at least one tissue sample from a body of a living being, comprising: operating the biopsy device to position a hollow needle and a sample-receiving device at a target site in the body of the living being;positioning the sample-receiving device in
1. A method for operating a biopsy device to acquire at least one tissue sample from a body of a living being, comprising: operating the biopsy device to position a hollow needle and a sample-receiving device at a target site in the body of the living being;positioning the sample-receiving device in an extended position relative to the hollow needle, such that a cavity of the sample-receiving device extends from a distal end of the hollow needle so that tissue is received in the cavity;longitudinally displacing the hollow needle in a distal direction to sever the tissue received in the cavity from surrounding tissue to form a tissue sample in the cavity of the sample-receiving device;retracting the sample-receiving device through the hollow needle to a sample removal position, the tissue sample being simultaneously transported to the sample removal position by the sample-receiving device;operatively connecting a liquid supply unit to the cavity of the sample-receiving device when the sample-receiving device is at the sample removal position; anddelivering a lateral flow of a flushing liquid from the liquid supply unit to the cavity of the sample-receiving device to facilitate a lateral tissue sample ejection from the cavity. 2. The method of claim 1, wherein the liquid supply unit includes a pump for supplying the flushing liquid from the liquid supply unit under pressure to the cavity of the sample-receiving device. 3. The method of claim 2, wherein the pump is a peristaltic pump. 4. The method of claim 1, wherein the liquid supply unit includes a liquid supply chamber and a plunger movably disposed in the liquid supply chamber. 5. The method of claim 1, comprising releasably coupling a disposable unit to a handle unit, the disposable unit having the hollow needle and the sample-receiving device, the liquid supply unit being releasably mounted to one of the handle unit and the disposable unit. 6. The method of claim 1, comprising receiving the tissue sample ejected from the cavity of the sample-receiving device in a sample-collecting device. 7. The method of claim 6, wherein the sample-collecting device includes a plurality of receptacles configured to receive tissue samples, the method comprising selecting a respective receptacle of the plurality of receptacles to receive a respective tissue sample. 8. The method of claim 1, wherein the act of retracting the sample-receiving device is effected using a bendable elongate element. 9. The method of claim 1, wherein the sample-receiving device comprises a tube having a side port forming the cavity, the method further comprising applying a vacuum to the cavity. 10. The method of claim 1, comprising applying a vacuum to the cavity through a longitudinally extending passage in the sample-receiving device. 11. The method of claim 1, comprising: arresting the sample-receiving device in the sample removal position; anddetecting a distance between the extended position and the sample removal position. 12. A method for operating a biopsy device for acquiring at least one tissue sample from a body of a living being, comprising: (a) providing a disposable unit, including: a hollow needle having a distal end portion with a circumferential cutting edge;a sample-receiving device received in the hollow needle, the sample-receiving device having a tapered distal tip and a cavity configured to receive a tissue sample, the sample-receiving device being configured to move in the hollow needle between a first extended position and a second retracted position; anda 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(b) releasably mounting the disposable unit to a handle unit, the handle unit including: a drive unit configured to drive the transport device; anda 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. 13. The method of claim 12, wherein the liquid supply unit includes a pump for supplying the flushing liquid from the liquid supply unit under pressure to the cavity of the sample-receiving device. 14. The method of claim 12, comprising providing a sample-collecting device configured to receive the tissue sample ejected from the cavity of the sample-receiving device by the flushing liquid when the sample-receiving device is in the second retracted position. 15. The method of claim 12, comprising: operating a first user-operable firing mechanism to cause the hollow needle and the sample-receiving device to be longitudinally displaced in a distal direction, so as to penetrate body tissue; andoperating a second user-operable firing mechanism to cause the hollow needle to be longitudinally displaced in a distal direction from a first position, in which the sample-receiving device projects from the distal end portion of the hollow needle, to a second position, in which the hollow needle accommodates the cavity of the sample-receiving device, so as to sever the tissue sample from remaining body tissue at the body site. 16. The method of claim 12, comprising: arresting the sample-receiving device in the second retracted position; anddetecting a distance between the first extended position and the second retracted position. 17. A method for acquiring at least one tissue sample from a body of a living being, comprising: providing a hollow needle having a distal end portion with a cutting edge configured to sever a tissue sample from body tissue;providing 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;providing a transport device coupled to the sample-receiving device, the transport device moving the sample-receiving device relative to the hollow needle; andproviding a liquid supply unit for carrying and supplying 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. 18. The method of claim 17, comprising: providing a handle unit having a drive unit configured to drive the transport device;releasably coupling a disposable unit to the handle unit, the disposable unit including the transport device, the hollow needle and the sample-receiving device; andreleasably mounting the liquid supply unit to one of the handle unit and the disposable unit. 19. The method of claim 17, comprising selecting a respective receptacle of a plurality of receptacles to receive a respective ejected tissue sample. 20. The method of claim 17, wherein the transport device comprises a bendable elongate element.
