Claim:
1. A surgical instrument comprising: a mount body having a top portion, a distal end, a proximal end and a bottom portion wherein the bottom portion comprises a mounting mechanism configured to reversibly clamp the surgical instrument to a retractor system; an actuator mounted to the mount body at a proximal end region of the mount body; a joint member pivotally mounted at a distal end portion of the mount body to allow positioning of a proximal portion of an arm extending distally from the joint member from a left distal region of the mount body to a right distal region of the mount body and vice versa without causing movement of the actuator, the joint member configured to at least partially constrain movement of the proximal portion of the arm to a plane, wherein a proximal link of the arm immediately adjacent to the joint member is pivotable to a substantially perpendicular position with respect to the mount body; and a working end mounted to a distal end portion of the arm, wherein the actuator is rotatably mounted to the mount body at the proximal end of the mount body, wherein the actuator is configured to change a state of the arm from a flexible state to a rigid state by rotation of the actuator in a first rotational direction, and from the rigid state to the flexible state by rotation of the actuator in a counter-rotational direction.
