<p>The surgical instrument (20) on a swing axis (16) at the end of a shaft, e.g. as an endoscope, is given a swing movement by a force transfer unit (53) through a control curve (37). The control curve has a shape which gives an increasing torque to the swing movement of the instrument, as the force transfer unit is moved to give a stronger cutting action or grip on the organ tissue.</p> |
