ABSTRACT:
A biopsy device includes a cylindrical outer cannula with a proximal end and a distal end, has a handle in the region of its proximal end and a cutting rim in the region of its distal end. An intermediate cannula, with a proximal end and a distal end, is disposed inside the outer cannula. The proximal end of the intermediate cannula is fixed to the proximal end of the outer cannula. The distal end of the intermediate cannula is provided with elastic resection means having their free ends bent inward, when they are in non-operation condition. An inner cannula, of smaller diameter, is slidably located inside the intermediate cannula. The inner cannula can be moved axially with respect to the intermediate and outer cannulas between an advanced position, in which said cannula pushes the resection means keeping their free ends open, and a retracted position, in which these resection means are released, and the free ends of the are bent elastically.
