More Information
Summary:This invention relates to a biopsy device consisting of an inner cannula (4) and an outer hollow tube (1), a handle (7) which may be removably attached to the outer hollow tube, a locking system to secure the inner cannula and/or the attenuator in the outer hollow tube, and characterized in that the tip of the outer hollow tube is ellipse shaped and extends beyond the inner cannula, the latter ending in a blunt edge. The blunted tip of the outer hollow tube together with the sharpened ending of the inner cannula determines the cutting edge of the device. In combination the distal ends of inner cannula and outer hollow tube determine the biopsy depth size and shape of the biopsy sample in a reproducible way. In one embodiment of the present invention, the length of the inner cannula can be controlled, allowing varying the aforementioned sample parameters as desired.
