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.

Abstract: An insulation pressure-resistant cylinder body of submarine (undersea) cable equipment, submarine cable equipment, and a manufacturing method are provided. The insulation pressure-resistant cylinder body includes: an installation cylinder, an insulation layer, and a pressure-resistant cylinder, disposed sequentially from inside to outside, where a first groove is opened on an outer surface of the installation cylinder, and a second groove is opened on an inner surface of the pressure-resistant cylinder, the second groove is interlaced with the first groove, and the insulation layer is closely adhered to the outer surface of the installation cylinder and the inner surface of the pressure-resistant cylinder.
