Abstract
A biopsy device for harvesting tissue samples from a body of a living being, e.g. in percutaneous aspiration biopsy, includes an outer needle and a sample-receiving device for receiving a severed tissue sample, the sample-receiving device being movable in the hollow needle. The device includes a transport device for moving the sample-receiving device in the hollow needle, the transport device comprising a bendable elongate element, such as a steel wire, a toothed wire made from e.g. a plastics material or a Bowden cable capable of pushing and pulling the sample-receiving device in distal and proximal directions, respectively. A coiling device is provided for the bendable elongate element. The bendable elongate element and the coiling device may be included in a disposable unit, which is attachable to a hand-held unit including a motor for driving the transport device. Orientation means are provided for appropriately orienting the sample-receiving device with respect to the hollow needle.
