A disposable unit for a biopsy device includes a hollow needle configured to define a longitudinal path. A sample-receiving device having a cavity is configured to move in the hollow needle along the longitudinal path between an extended position and a retracted position. A transport device is configured to move the sample-receiving device in the hollow needle between the extended position and the retracted position. The transport device includes a bendable elongate element having a proximal portion and a distal end, the distal end being connected to the sample-receiving device. The bendable elongate element has a tooth surface that is engaged by a rotatable gear. A coiling device is configured to coil the proximal portion of the bendable elongate element as the sample-receiving device is moved linearly along the longitudinal path from the extended position to the retracted position by operation of the rotatable gear.

1. A disposable unit for a biopsy device, comprising: a hollow needle having a distal end portion having a cutting edge, and configured to define a longitudinal path;a sample-receiving device having a cavity configured to receive tissue, the sample-receiving device configured to move in the hollow needle along the longitudinal path between an extended position, in which the cavity of the sample-receiving device projects from the distal end portion of the hollow needle, and a retracted position, in which the cavity of the sample-receiving device is positioned proximal to the distal end portion of the hollow needle to facilitate removal of the tissue from the cavity; anda transport device configured to move the sample-receiving device in the hollow needle between the extended position and the retracted position, wherein the transport device includes: a bendable elongate element having a proximal portion and a distal end, the distal end being connected to the sample-receiving device, the bendable elongate element having a toothed surface;a rotatable gear engaged with the toothed surface of the bendable elongate element; anda coiling device configured to coil the proximal portion of the bendable elongate element as the sample-receiving device is moved linearly along the longitudinal path from the extended position to the retracted position by operation of the rotatable gear. 2. The disposable unit of claim 1, wherein the coiling device is arranged at a proximal end of the disposable unit at a location proximal to the retracted position. 3. The disposable unit of claim 1, wherein the bendable elongate element has a polygonal cross-section. 4. The disposable unit of claim 1, wherein the toothed surface of the bendable elongate element has a row of regularly spaced teeth. 5. The disposable unit of claim 1, comprising a swivel joint interposed in attachment to the sample-receiving device and the bendable elongate element to allow the sample-receiving device to rotate relative to the bendable elongate element. 6. The disposable unit of claim 1, comprising at least one support configured to support the bendable elongate element in a lateral direction to avoid flexing the bendable elongate element in the lateral direction. 7. The disposable unit of claim 6, wherein the at least one support comprises two opposing wall sections arranged with a mutual clearance corresponding to a thickness of the bendable elongate element, the bendable elongate element being free to slide in a longitudinal direction between the two opposing wall sections. 8. The disposable unit of claim 6, wherein the at least one support comprises two opposing roller elements arranged with a mutual clearance corresponding to a thickness of the bendable elongate element, the bendable elongate element being free to slide in a longitudinal direction between the two opposing roller elements. 9. The disposable unit of claim 1, wherein the bendable elongate element is configured so that a longitudinal portion of the bendable elongate element does not flex outwardly from the longitudinal path when the sample-receiving device is pushed from the retracted position to the extended position. 10. The disposable unit of claim 1, comprising a physical non-transitory electronic memory device. 11. A biopsy device for removing at least one tissue sample from a body of a living being, the biopsy device comprising: a handle unit; anda disposable unit releasably attached to the handle unit, the disposable unit including: a hollow needle having a distal end portion having a cutting edge, and configured to define a longitudinal path;a sample-receiving device having a cavity configured to receive tissue, the sample-receiving device configured to move in the hollow needle along the longitudinal path between an extended position, in which the cavity of the sample-receiving device projects from the distal end portion of the hollow needle, and a retracted position, in which the cavity of the sample-receiving device is positioned proximal to the distal end portion of the hollow needle to facilitate removal of the tissue from the cavity; anda transport device configured to move the sample-receiving device in the hollow needle between the extended position and the retracted position, wherein the transport device includes: a bendable elongate element having a proximal portion and a distal end, the distal end being attached to the sample-receiving device, the bendable elongate element having a toothed surface;a rotatable gear engaged with the toothed surface of the bendable elongate element; anda coiling device configured to coil the proximal portion of the bendable elongate element as the sample-receiving device is moved linearly along the longitudinal path from the extended position to the retracted position by operation of the rotatable gear. 12. The biopsy device of claim 11, comprising a control system configured to control movement of the transport device to effect movement of the sample-receiving device between the extended position and the retracted position, and configured to control movement of the transport device to arrest the sample-receiving device in the retracted position. 13. The biopsy device of claim 12, wherein the control system is configured to automatically detect a distance of the movement between the extended position and the retracted position. 14. The biopsy device of claim 12, wherein the control system is configured to activate the transport device to retract the sample-receiving device toward the retracted position and to record as a proximal extremity a maximum retraction extent of the sample-receiving device, and the control system configured to utilize the recorded proximal extremity as a position reference point for a subsequent arresting of the sample-receiving device in the retracted position. 15. The biopsy device of claim 14, wherein the proximal extremity and the retracted position are at different longitudinal positions relative to the handle unit. 16. The biopsy device of claim 12, wherein the sample-receiving device has a pre-defined range of movement between a distal extremity and a proximal extremity, and wherein the control system comprises a sensor configured to detect when the sample-receiving device reaches the proximal extremity. 17. The biopsy device of claim 16, wherein the proximal extremity of the sample-receiving device is defined by a mechanical stop for the sample-receiving device, and wherein the proximal extremity and the retracted position are at different longitudinal positions relative to the handle unit. 18.
