    • A total wrist prosthesis which has a metacarpal component and a radial component having ellipsoidal articulating surfaces. The metacarpal component and the radial component each have a fixation stem for insertion into the third metacarpal and the radius respectively. The fixation stem of the metacarpal component is curved dorsally to volarly so as to approximate the natural curvature of the third metacarpal and capitate of the human hand. The fixation stem of the metacarpal component has a center line which attaches to the head of the metacarpal component which contains the articulating surface dorsally from the minor axis of the ellipsoidal articulating surface. The fixation stem and the head of the metacarpal component have a plurality of wings attached thereto and a spur to prevent rotation of the device once inserted into the metacarpal. Also, the surface area of the metacarpal component proximal to the ellipsoidal articulating surface is coated with porous coating to aid in cement fixation.The radial component of the wrist prosthesis also has a fixation stem which is fixedly attached to a holder which receives a bearing member that defines a concave ellipsoidal articulating surface which is complimentary to the convex articulating surface of the metacarpal component. The center line of the fixation stem of the radial component is displaced dorsally from the minor axis of the concave articulating surface and also radially from the minor axis. A porous coating is also present about the base of the holder and the fixation stem. The curvature of the metacarpal fixation stem and the displacement of the center lines of both fixation stems relative to the minor axis of the ellipsoidal surfaces to which they are attached cause the center of rotation and flexion-extension motion and radial-ulnar-deviation to approximate the natural centers of rotation of flexion-extension motion and radial-ulnar-deviation.
    • 具有掌骨部件和具有椭圆形关节表面的径向部件的总腕部假体。 掌骨部件和径向部件各自具有分别用于插入第三掌骨和半径的固定杆。 掌骨部件的固定柄部向右弯曲,以接近人的手掌的第三掌骨和头皮的自然曲率。 掌骨部件的固定柄具有中心线,该中心线从椭圆形关节表面的短轴向背侧附着到掌骨部件的头部,该头骨部分包含铰接表面。 固定杆和掌骨部件的头部具有附接到其上的多个翼片,并且一旦插入到掌骨中则防止装置旋转。 此外,靠近椭圆形关节表面的掌骨部件的表面积涂覆有多孔涂层以帮助水泥固定。 腕部假体的径向部件还具有固定连接到保持器的固定杆,所述保持器容纳限定与掌骨部件的凸形关节表面互补的凹形椭圆形关节表面的轴承部件。 径向部件的固定杆的中心线从凹形铰接表面的短轴向后偏移并且从短轴径向偏移。 围绕保持器和固定杆的基部也存在多孔涂层。 掌骨固定杆的曲率和两根固定杆的中心线相对于它们所连接的椭圆形表面的短轴的位移导致旋转中心和屈曲伸展运动和径向尺度偏差近似 屈曲伸展运动和径向尺骨偏离的自然旋转中心。

    • Picture or Plaque Hanging Aid comprising: a length of stretchable elastic band, a rigid hook fixedly attached to each end of said band, and a bead frictionally mounted to said elastic band so that said bead can be slid to any portion of said band and remain in place when released. A preferred embodiment includes wherein a plurality of beads are frictionally mounted to said elastic band for marking a plurality of anchor placing locations. The user hooks the elastic band to the back of the plaque or picture, slides the ball to the anchor fastening location, places a transferrable mark on the bead with an ink pen so that when the picture or plaque is placed in the desired location on a wall, the mark is transferred to the wall thereby indicating the spot where a picture or plaque hanging anchor is to be fastened to the wall.
    • 图像或匾悬挂辅助装置包括:长度可伸缩的弹性带,固定在所述带的每个端部的刚性钩和摩擦地安装到所述弹性带上的珠,使得所述珠能够滑动到所述带的任何部分并保持 释放时就位。 一个优选实施例包括其中多个珠子摩擦地安装到所述弹性带上以标记多个锚定位置。 使用者将弹性带钩到斑块或图片的背面,将球滑动到锚定固定位置,用墨水笔将可转印标记放置在珠子上,使得当图像或斑块放置在所需位置时 墙壁,标记被转移到墙壁,从而指示将图片或匾挂锚固定在墙上的位置。
