The disclosed technology relates to a rod bending machine for use with a robotic surgical system in an operating room. The system which is capable to bend rods for surgeries directly in the operating room. The rigidity of the rods is such that the robotic arm alone would have to be huge to provide sufficient forces and torques. This invention introduces bending module integrated into robotic system which allows free bending of rods within limits required for surgeries.

A handle includes handle grips and a handle pipe including an attachment portion, a first grip portion, a second grip portion, a first bent portion between the attachment portion and the first grip portion, and a second bent portion between the attachment portion and the second grip portion. The first grip portion includes a first overlapping region overlapping a first handle grip and a first non-overlapping region not overlapping the first handle grip. The second grip portion includes a second overlapping region overlapping a second handle grip and a second non-overlapping region not overlapping the second handle grip. The first and second non-overlapping regions each include a thick portion having a thickness larger than, or equal to, a thickness of the attachment portion. The first and second overlapping regions each include a thin portion having a thickness smaller than the thickness of the thick portion.
