    • An anti-subsidence dynamic hip screw comprises of a barrel having a connection portion and a tube-type extending portion angled a predetermined angle with the connection portion, and a first long groove and a first limit portion disposed at the inner wall of the extending portion respectively; a lag screw having an inside end disposed threading screw at its outer edge and a outside end with a predetermined length passed through in the extending portion by the way of reciprocation; a second long groove and a second limit portion disposed at the lag screw respectively related to the first long groove and the first limit portion, each first limit portion and second limit portion used for preventing the lag screw from rotating inside the extending portion; a blade piece with a predetermined length simultaneously passed through and retained in the first long groove and the related second long groove; a compressing screw having an inside end screwed with the outside end of the lag screw and an outside end retained in the outside end of the extending portion. The above structure is not only easy to assembly, especially for the effect of decreasing the subsidence of the femoral head, but also makes the effect more obvious when using for the hip fracture of the osteoporosis body.
    • 一种防沉降动力髋螺钉包括具有连接部分的筒体和与连接部分成一定角度的管状延伸部分,以及设置在延伸部分的内壁处的第一长槽和第一限位部分 分别; 具有内端的拉杆螺钉,其内端在其外缘设置有螺纹螺钉,并且具有预定长度的外端通过往复运动在所述延伸部分中穿过; 分别与所述第一长槽和所述第一限制部分相关联地设置在所述拉力螺钉上的第二长槽和第二限制部,用于防止所述拉力螺钉在所述延伸部内部旋转的第一限制部和第二限制部; 具有预定长度的刀片同时通过并保持在第一长槽和相关的第二长槽中; 压缩螺钉的内端与拉伸螺钉的外端螺合,外端保持在延伸部的外端。 上述结构不仅容易组装,特别是对于降低股骨头下沉的效果,而且当用于骨质疏松症的髋骨骨折时,效果也更加明显。

    • A displacement leaf spring and an artificial intervertebral disc containing the same, particularly about the artificial intervertebral disc using the displacement leaf spring to cushion axial compression, wherein the artificial intervertebral disc includes a displacement leaf spring and the displacement leaf spring further includes an upper plate, an inclined plate, and a lower plate. The upper plate has a first breach, and the inclined plate has a first connecting side which connects to one side of the first breach. There is an angle between the inclined plate and the upper plate. The inclined plate has a second breach, and the lower plate has a second connecting side which connects to one side of the second breach. There is an angle between the lower plate and the inclined plate, and the lower plate parallels the upper plate. The artificial intervertebral disc equipped with the displacement leaf spring further comprises a top plate, a bottom plate, a core structure, and a socket structure. The top and bottom plate connect to the bottom of the upper vertebral body and the top of the lower vertebral body respectively. The form of the core structure fits in the socket structure. The core structure and the socket structure are installed between the top and bottom plate to make the artificial intervertebral disc have a wide range of activity angle and capability to cushion the axial compression.
    • 位移板簧和包含其的人造椎间盘,特别是关于使用位移板簧缓冲轴向压缩的人造椎间盘,其中人造椎间盘包括位移板簧,并且位移板簧还包括上板, 倾斜板和下板。 上板具有第一突出部,并且倾斜板具有连接到第一突出部的一侧的第一连接侧。 倾斜板和上板之间有一个角度。 倾斜板具有第二突破,下板具有连接到第二突破的一侧的第二连接侧。 下板与倾斜板之间有一角度,下板与上板平行。 配备有位移板簧的人造椎间盘还包括顶板,底板,芯结构和插座结构。 顶板和底板分别连接到上椎体的底部和下椎体的顶部。 核心结构的形式适合插座结构。 核心结构和插座结构安装在顶板和底板之间,使得人造椎间盘具有宽范围的活动角度和缓冲轴向压缩的能力。
