1. A medical instrument for manipulating internal organs of a body, comprising;

  • a rod, having a retractor body arranged at a distal end of the rod and a handle at a proximal end of the rod;

    a rigid flexion resisting shaft, having a proximal end and a distal end, for guiding said rod, said rod being movable with respect to the shaft in an axial direction of said rod;

    wherein said retractor body comprises a multi-joint lever system of articulated arms connected to one another to be pivotably movable, which can be brought into an open position by movement of the rod in a first direction with respect to the shaft, and can be brought into a closed position by movement of the rod in a second direction with respect to the shaft;

    wherein said multi-joint lever system comprises two pairs of articulated arms, each pair having a proximal end, a distal end and a central joint where two articulated arms are joined by a hinge, each pair being assigned to an opposite side of said rod guided by said shaft, said distal end of each pair being pivotally connected to said distal end of said rod and said proximal end of each pair being pivotally connected to said distal end of said shaft.
