Abstract
A rod bender includes a first handle arm and a second handle arm coupled to a first pivot point. A body portion of the rod bender is coupled to the first handle arm at a second pivot point and the second handle arm is coupled to the body portion at a third pivot point. The body portion also includes first and second distal arms configured with first and second rolling elements and navigation arrays coupled to distal ends of the first and second distal arms. A barrel is provided on the body portion which is positioned on a center area of the body portion. The navigation arrays have optical markers that are tracked by camera. A three-dimensional reconstruction of a rod bent by the rod bender is created using tracked position of the optical markers during bending.
