Rod insertion navigation system

A real-time simu lation-based rod insertion navigation system comprising:

• a camera;
• a plurality of pedicle screws inserted and fixed into pedicles;
• a first marker attached to an upper portion of each of the plurality of pedicle screws;
• a rod insertion device equipped with a rod inserted into a side of heads of the plurality of pedicle screws and fixed to the heads of the pedicle screws;
• a second marker attached to the rod insertion device;
• and
• a control unit configured to, when the rod is inserted into the heads of the pedicle screws by the rod insertion device, determine a position and angle change of the pedicle screws and the rod insertion device equipped with the rod using an image captured by the camera of the first marker and the second marker, and display a real-time simulation image by synthesizing in real time an image reflecting the position and angle changes of the pedicle screws and the rod insertion device equipped with the rod.
