Tissue punch
 A tissue punch for removing tissue parts from the human or animal body is described, which comprises the actual operating instrument, as well as a separate driving unit, which is connected by means of a flexible force transmission member to the operating instrument. The operating instrument comprises a surgeon-guided outer tube and an inner tube slidably arranged therein having a cutting edge for separating the tissue parts. The inner tube is also supplied with a vacuum by means of a hose connection for removing a separated tissue part from said inner tube. The operation of the inner tube or the cutting edge connected thereto, as well as the suction are controlled by a separate control unit.
