A surgical instrument having a distally located surgical or diagnostic tool, a plurality of links proximal of the surgical or diagnostic tool, with at least two or more adjacent links being moveable relative to one another; and a joint assembly proximal of the plurality of links, with the joint assembly connected to a manually moveable handle extending proximally of the joint assembly. The links are operably connected to the joint assembly by cables such that manual movement of the handle causes a corresponding movement of the two or more adjacent links. |
