Abstract
A surgical laser backstop instrument comprising a rod, a backstop pivotally mounted to one end of the rod, and a backstop adjustment mechanism mounted to the other end of the rod. The backstop is comprised of a non-reflective material. The backstop adjustment mechanism controls the movement of the backstop. The backstop is a flat section of titanium-coated material and is movable between a position longitudinally aligned with the axis of the rod and a position transverse to the axis of the rod. The backstop adjustment mechanism comprises a body connected to the other end of the rod, a line fastened at one end to the backstop and extending through the rod, and a movement actuator mechanism connected to the other end of the line for controlling the pivotal movement of the backstop. This movement actuator mechanism includes a knob rotatably mounted to the body, a rack assembly placed within the body and connected to the end of the line, and a pinion gear engaging the rack assembly and connected to the knob such that rotational movement of the knob causes movement of the rack assembly.
