  • Patent number: 10813726
    Abstract: A periosteal elevator applied to comb and elongate a subcutaneous fibrous tissue includes a stem bar, a first spoon end, and a plurality of hook-shaped comblike structures separated to each other. The first spoon end, fixed to a first end portion of the stem bar, further has a spoon-end edge. The plurality of hook-shaped comblike structures, fixed to the spoon-end edge, further have an extension portion and a hook-like comb portion. The extension portion is extended from the spoon-end edge, and the hook-like comb portion is extended from the extension portion. When the subcutaneous fibrous tissue is cut and separated from a bone tissue, the plurality of hook-shaped comblike structures can comb and elongate the subcutaneous fibrous tissue. In addition, a comb surface of the hook-like comb portion and an inner-side extension surface of the extension portion are together to form an angle within a range of 60 and 100 degrees.

  • Patent number: 10753442
    Abstract: A dustproofing device for use with a linear module includes a dustproofing band disposed around a first pulley pivotally connected to a first end unit and a second pulley pivotally connected to a second end unit. Two ends of the dustproofing band fixedly connect to a fixing platform. The fixing platform fixedly connects to a moving platform of the linear module. A top lid is fixedly disposed on the first end unit and the second end unit and covers the fixing platform, so as for the dustproofing device to be mounted on the linear module. Since the linear module is covered with the first end unit, a first lateral lid, the second end unit and the top lid, not only is the linear module rendered dustproof, but it also takes less time than before to mount the dustproofing device in place.

  • Patent number: 10642322
    Abstract: A heat dissipation module suitable for an electronic device is provided. The electronic device has a heat source. The heat dissipation module includes an evaporator and a pipe assembly. An internal space of the evaporator is divided into a first space and a second space, and the heat source is thermally contacted with the second space. The pipe assembly is connected to the evaporator to form a loop. A working fluid is filled in the loop. The working fluid in liquid receiving heat from the heat source is transformed into vapor and flows to the pipe assembly. Then, the working fluid in vapor is transformed into liquid by dissipating heat in the pipe assembly and flows to the first space of the evaporator. The working fluid in liquid is stored in the first space and is used for supplying to the second space.
