    • A screw insertion/extraction device is disclosed that is useful as a tool for screw insertion and extraction procedures. The device includes a shaft sleeve that is formed to define a passage for accommodating the shaft of a wrench. In an exemplary embodiment, the shaft sleeve has a proximal portion and a distal portion interposed by an intermediate portion, where the proximal and distal portions extend along opposite sides of a central axis of the wrench shaft passage and the intermediate portion extends both along and about the central axis to connect the proximal and distal portions. A shoulder portion extends inwardly from the distal end of the shaft sleeve for engaging the base of a screw head such that the screw head can be captured between the distal end of a wrench and the shoulder portion of the shaft sleeve.
    • 公开了一种螺钉插入/提取装置,其可用作用于螺钉插入和提取程序的工具。 该装置包括轴套,其形成为限定用于容纳扳手的轴的通道。 在一个示例性实施例中,轴套具有一个中间部分插入的近端部分和远端部分,其中近端部分和远端部分沿着扳手轴通道的中心轴线的相对侧延伸,并且中间部分沿着和围绕 连接近端和远端部分的中心轴线。 肩部从轴套的远端向内延伸,用于接合螺钉头的底部,使得螺钉头可以在扳手的远端和轴套的肩部之间被捕获。
