1. A microsurgical tool, comprising:

  • an elongated body having a distal end;

    a platform moveably coupled to the distal end of the elongated body; and

    a linkage coupling the distal end of the elongated body to the platform to allow the platform to move relative thereto, wherein the linkage comprises;

    a first arm directly operatively coupled to the distal end of the elongated body at a first proximal hinge and to the platform at a first distal hinge, the first arm having a first redirect surface,a first force transfer element disposed around the first redirect surface before terminating at the first arm such that pulling the first force transfer element pivots the first arm about the first proximal hinge with a first amplified range of motion,a second arm directly operatively coupled to the distal end of the elongated body at a second proximal hinge and to the platform at a second distal hinge, the second arm having a second redirect surface, anda second force transfer element disposed around the second redirect surface before terminating at the second arm such that pulling the second force transfer element pivots the second arm about the second proximal hinge with a second amplified range of motion.
