This project is India's first robotic system for spinal surgery, an image guided robotic system for minimally invasive and open spine surgeries that are less painful and more affordable. The workflow starts by registering the robot, patient and other external tool trackers using IR camera (NDI). The surgical points are registered using surface registration technique which is followed by the robot’s movement. The trajectory and path of the robot are computed according to the surgical points to orient the robot. A calibration step will be performed for the external tracker to align the world coordinates to the 3D model and robot coordinate. Once calibrated, any movement of the tracker can be extrapolated on to the 3D model and the surgery plan. The complete workflow for pedicle screw insertion is shown in the video.
