Abstract
A 2D image-guided surgical robot system for drilling operations includes surgical image acquisition equipment, robot positioning and drilling equipment, and a remote operation workstation. To perform a drilling operation, images of the surgery area are acquired with the image acquisition equipment and are registered to the robot, and a distortion correction is performed. A drilling path is assigned by a doctor through the GUI of the remote operation workstation, and the remote operation workstation calculates the robot motion quantity using a position-based method and moves the robot accordingly. Based on the relative position of the surgical tool and drilling path in the images, the remote operation workstation calculates a motion quantity using image feedback and controls the robot to make further fine adjustments to the drilling path. The robot then performs the drilling operation with an electric drill or holds a drill guide for doctors to perform the drilling manually.
