Abstract
A compound rod bender includes a first distal arm, a second distal arm, a rotating and translating barrel, and a compound hinge. The barrel includes a plurality of bending surfaces configured to be selectively positioned to contour a rod. The barrel is positioned on a pivot point between the first and second distal arms. The compound hinge includes at least one additional pivot point configured to increase a bending force when the rod is contoured.
