摘要： The present invention relates to a surgical cutting instrument for minimally invasive surgery comprising a gripping element, a hollow stem mounted as an extension of said gripping element along a longitudinal axis of the instrument; a tie rod housed in the hollow stem and having a proximal end coupled to a control lever in said gripping element and a distal end hinged to a blade element; a covering and guiding sheath for said blade element as an extension of said stem. The blade element has a fulcrum that is movable in said covering and guiding sheath and is configured to pass from an inactive position in which it is hidden housed in said covering sheath and an active position protruding outwardly through a window of said covering sheath and vice versa.
