ABSTRACT:
An instrument and method for bending a surgical implant, such as a spinal rod, includes a lever pivotally connected to a handle through a movable linkage system. The movable linkage system includes one or more bearing surfaces for applying a force to a first portion of the surgical implant while a rod seat connected to the handle holds an adjacent second portion of the surgical implant in a fixed position, thereby causing the surgical implant to bend between the first and second portion. The instrument can be easily operated using a single hand, is easy to control and requires a relatively small amount of force to bend a surgical implant. The instrument can include an automatic advancement means for advancing the surgical implant after bending to bend another portion of the surgical implant by a selected amount. The instrument can also be used for bending spinal rods having a non-circular cross-section in multiple planes.
