Abstract:
1. A biopsy device for harvesting at least one tissue sample from a body of a living being, the device comprising: a hollow needle with a distal end portion having a cutting mechanism for severing the at least one tissue sample; a sample-receiving device with a cavity for receiving the at least one severed tissue sample, the sample-receiving device being received in the hollow needle and movable in the hollow needle; a drive mechanism configured to displace the hollow needle in a distal direction relative to the sample-receiving device to sever tissue received in the cavity of the sample-receiving device; a transport device including a bendable elongate element that is coupled to the sample-receiving device to move the sample-receiving device in the hollow needle, wherein the bendable elongate element is bendable away from the longitudinal direction of the hollow needle; and a spiral-shaped wall arranged at a proximal end of the transport device, the spiral-shaped wall defines a spiral-shaped cavity, the spiral-shaped cavity configured to receive the bendable elongate element as the sample-receiving device is retracted through the hollow needle so that each successive winding of the bendable elongate element is separated from one another.
