Abstract: A control method for an arthroplasty surgical robot includes: capturing a bone image, transmitting the image to a computer system, and acquiring image data of a bone; selecting a suitable prosthesis model and placing it on a diseased joint for matching, wherein the overlapping part between the model and the bone is the part that needs to be removed and replaced; mounting signal sources; capturing a bone image again, including the signal sources and the joint part; establishing a coordinate system using the signal sources as the origin, and calculating and memorizing an interface between the model and the bone overlapping part and the coordinates of the interface in the coordinate system; and receiving the coordinates by a surgical robot, and obtaining the positional coordinates by the surgical robot of a part of the diseased joint that needs to be removed, and performing a surgical operation by the surgical robot.

Abstract: A kind of bone plate gimbal lock pressure device. The body of the bone plate (1) has a microscler slippery hole (2), in which there has a locking slider (3); on the slider (3) there is a cone-shaped screw hole (3-3) with a cone-head screw (4) inside. The shapes at two inside sides of the microscler slippery hole (2) cross section are internal arc-shaped, and the shapes of the two sides of the locking slider (3) are correspondingly external arc (3-1); in the middle of the locking slider (3) there is a notch (3-2). The locking slider (3) can slide in the microscler slippery hole (2) to meet the pressure requirement, and also can sway from side to side to adjust the direction of the cone-head screw (4) according to the requirement. The two sides of the locking slider (3) are arc; after tightening the screw (4), the arc contact will make the locking slider (3) not take off.
