Abstract
A biopsy device for harvesting tissue samples from a body of a living being, e.g. in percutaneous aspiration biopsy, includes a handle unit, a hollow needle comprised in a disposable unit, which is releasably attached to the handle unit, and a sample-receiving device, which is movable in the hollow needle between two positions. Tissue is severed when the sample-receiving device is in a first one of the positions, and the severed tissue sample is ejected from the sample-receiving device in a second one of the two positions. A control system is provided for controlling movement of the sample-receiving device and for arresting the sample-receiving device in the second position. The distance between the two positions and/or a length of the hollow needle may be detectable in a calibration cycle, which is automatically initiated upon attachment of the disposable unit to the handle unit. The disposable unit may include electronic memory means for communicating with the control system.
