  • Publication number: 20220346001
    Abstract: A cell dwelling method, a terminal, and a non-transitory storage medium. The method includes searching for frequency points of pre-stored cells, and determining first-type cells from the pre-stored cells, the pre-stored cells and the first-type cells being preset anchor cells configured to access a first network, and the first-type cells being the preset anchor cells determined by performing a frequency-scanning process for the pre-stored cells; performing another frequency-scanning process and obtaining frequency-scanning cells, and adding the frequency-scanning cells to a list of candidate cells; the frequency-scanning cells including the first-type cells, and the frequency-scanning cells in the list of the candidate cells being sorted based on a preset sorting rule; and increasing priorities of the first-type cells in the list of the candidate cells, selecting a target cell of the first-type cells from the list of the candidate cells based on the priorities, and dwelling on the target cell.

  • Patent number: 10441373
    Abstract: A master-slave same structure teleoperation fracture reduction mechanism includes a frame assembly, two parallel platform assemblies, a top platform connecting plate (9), an operating handle assembly, two fixing assemblies, a controller (15), six movement assemblies and 24 hydraulic pipes (26). The operating handle assembly is located in the middle of the upper platform (5), and the two fixing assemblies are located on the top of the parallel platform assembly. The two parallel platform assemblies are disposed on the frame assembly; the controller (15) and the six movement assemblies are disposed on the frame assembly; A top platform connecting plate (9) is connected to the fixing assembly parallel platform assembly. The hydraulic pipes (26) is in communication with motion hydraulic cylinders (7a) and the other end of the hydraulic pipes is in communication with one of platform hydraulic cylinders (7b). The invention assists a doctor to achieve fracture reduction.

  • Publication number: 20180042622
    Abstract: The present disclosure relates to an anatomical locking guide steel plate for a complicated acetabulum fracture, an anatomical locking guide apparatus and matched guide sleeve apparatus. The inner side of said anatomical locking guide steel plate contacts with a face of the acetabulum, said anatomical locking guide steel plate includes three portions, a head of the steel plate, a body of the steel plate and a tail of the steel plate, said head of the steel plate, said body of the steel plate and said tail of the steel plate are jointed seamlessly. Using the steel plate provided by the present disclosure can reposition and fix the complicated acetabulum fracture efficiently. It can avoid shaping the steel plate in the surgery, so the operative time may be shortened, and the difficulty of the surgery may be lower. The surgical trauma is small, and the surgical bleeding is slight.

  • Patent number: 9610101
    Abstract: A long-bone fracture-reduction robot is provided, and includes a machine base; a support slidably connected onto the machine base and able to move up and down; a plurality of electro-hydraulic drivers; and a six-degrees-of-freedom parallel robot arranged on the support, with the motion of the robot in six degrees of freedom hydraulically controllable using the plurality of electro-hydraulic drivers. The long-bone fracture-reduction robot includes two long-bone-fixing frames, one frame being coupled to the support and other being coupled to the six-degree-of-freedom parallel robot. The two long-bone-fixing frames are arranged to be side by side. Each of the two long-bone-fixing frames is fixedly connected to a corresponding mounting-and fixing plate.
