  • Patent number: 12213254
    Abstract: A multi-layer printed circuit board includes a base-layer metal, multiple middle metal layers and a top-layer metal. The middle metal layers are stacked on the base-layer metal sequentially. The top-layer metal is disposed on the middle metal layers. The base-layer metal, each middle metal layer and the top-layer metal are formed with multiple through holes respectively. Part of the middle metal layers are separately formed with multiple hole groups corresponding to the through holes. Each hole group includes multiple passing holes. The passing holes jointly surround a corresponding one of the through holes to form multiple connecting channels. Therefore, the multi-layer printed circuit board may reduce the cooling speed of the through holes to avoid an excessively low temperature of a pad to affect the soldering efficiency with keeping the high-frequency transmission and the signal isolation.

  • Patent number: 11950771
    Abstract: The present invention provides a supporting hook structure, comprising a sleeve, a fixing rod, a first limit unit, a hook and a fixing device. The fixing rod is connected to the side surface of the sleeve. The hook body is connected to one end of the sleeve. The first limit unit is arranged on the side surface of the sleeve and adjacent to the hook body. The first limit unit makes the hook body rotates with the axis direction of the sleeve as a rotation axis. The fixing device is connected to the other end of the sleeve to fix the rotating position of the hook body. Through the above, the hook part enters the proximal thigh from a surgical entrance and the hook part rotates to make the hook part abut against the proximal femur to complete the positioning and fixation of the femur hook structure to the femur.
