Abstract:
1. A surgical hollow probe for minimally invasive tissue removal, comprising: an elongate hollow body, a distal opening in the region of the distal end of the hollow body for receiving tissue, and an electrically conductive ring-shaped or loop-shaped cutting element is adapted to be extended from the hollow body and is adapted to be applied to an HF-voltage source, for electrosurgically cutting out tissue in the area around the distal opening of the hollow body, characterised in that the cutting element is adapted to be extended from or pivoted out of the hollow body transversely with respect to the longitudinal axis of the hollow body and is then displaceable outside the hollow body along the hollow body; and characterized in that the cutting element is in the form of a wire loop whose both ends are secured to two separate guide elements which are guided slidably at the outside surface of the hollow body in longitudinal grooves parallel to the longitudinal axis of the hollow body.
