  • Publication number: 20220031398
    Abstract: A surface tracking-based surgical robot system for drilling operations includes surface scanning equipment, a robot arm, and a workstation. To perform a drilling operation, surface information for the target surgery area and the surgical tool held by the robot arm is simultaneously collected with the same surface scanning equipment. A preoperative 3D image of a surgical area and a CAD model of the surgical tool are registered to the collected surface information, through which the relative position between a surgical path and the surgical tool is obtained. Using this relative position, the robot arm aligns to the predefined surgical path using a feedback control method running on a workstation. The drilling operation is then autonomously executed by the robot arm or manually performed under the guidance of the surgical tool held by the robot arm.

  • Publication number: 20210259711
    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.

  • Publication number: 20210128261
    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.
