Abstract
A 2D image-guided surgical robot system for distal locking operations includes surgical image acquisition equipment, a robot arm, a robot end effector attached to the robot arm, and a remote operation workstation. To perform a distal locking operation, the position of the image acquisition device is adjusted to obtain a round outline of a lockhole in the image. A distortion correction is performed. The position of the target lockhole is assigned by a user through the GUI of the remote operation workstation, and the remote operation workstation calculates a robot motion quantity using image feedback control law and moves the robot accordingly. The “image-and-move” procedure is repeated several times until the drill guide is accurately aligned to the lockhole, then the distal locking operation is accomplished by first drilling a guide hole using a guide wire through the drill guide, and then screwing a locking screw through the guide hole.
