1. A medical bending system comprising:
an object to be bent;
a bending apparatus with which the object to be bent is bendable; and
a navigation device with a detection unit and a data processing unit,
the object to be bent comprising first markings arranged or formed on a surface of the object to be bent, and the bending apparatus comprising second markings that are arranged or formed on the bending apparatus,
said first and second markings being optically detectable by the detection unit,
the data processing unit being configured to determine at least one bending parameter during a bending operation based on information from the detection unit relating to the first and second markings,
wherein at least one of the following applies:
the first markings are integrated into or formed on said surface of the object to be bent by anodic oxidation, a shape-changing exposure method or water print coating; and
the second markings are integrated into or formed on said surface of the bending apparatus by anodic oxidation, a shape-changing exposure method or water print coating.
