    • An assembly for deploying a stranded support structure implant within a bone cavity to support the bone which defines the cavity comprises a support structure implant and an insertion tool. The support structure implant is formed from interlaced wires which extend from a first end of the structure towards an opposite second end. The structure flares outwardly from the first end to a maximum transverse dimension at a wide point between the first and second ends, and tapers inwardly between the wide point and the second end to a constant cross-section throat portion at the second end. The structure includes (i) a clip for controlling the spacing between the wires at the first end of the structure, in which the clip carries one of a spigot and a socket, and (ii) a ring clamp at the second end to retain the wires at the second end, in which the ring clamp has at least one clamp engagement formation. The insertion tool includes a probe end which carries the other of a spigot and a socket, so that the probe end and the clip can engage one another by means of the cooperating spigot and socket. An actuator moves the probe end relative to the tool engagement portion to cause the length of the implant to increase and its width to decrease.
    • 用于在骨腔内展开绞合的支撑结构植入物以支撑限定腔的骨的组件包括支撑结构植入物和插入工具。 支撑结构植入物由从结构的第一端向相对的第二端延伸的隔行线形成。 该结构在第一端部和第二端部之间的宽点处从第一端部向外突出到最大横向尺寸,并且在第二端部之间的宽点和第二端部之间向内逐渐变细到恒定的横截面的喉部分。 该结构包括(i)用于控制在结构的第一端处的线之间的间隔的夹子,其中夹子承载插口和插座中的一个,以及(ii)在第二端处的环夹具以保持 在第二端的线,其中环夹具具有至少一个夹紧接合结构。 该插入工具包括一个探针端,该探针端承载另一个插口和插座,以便探针端和夹可以通过协作的插口和插座彼此接合。 致动器相对于工具接合部移动探头端部,使得植入物的长度增加并且其宽度减小。

    • A cutting guide instrument for use in a cutting step in an orthopaedic surgical procedure comprises a reference component comprising a first element (26) which can be attached or otherwise aligned relative to the bone in a predetermined arrangement and a locator arm (30) . The invention further comprises a cutting block (28) comprising a reference surface (34) which can be engaged by a cutting tool to define the location and orientation of the tool during the cutting step. The cutting block further comprises at least one fixation bore (33) for receiving a fixation pin to fix the cutting block to the bone . The locator arm can be fitted against the reference surface so that the reference component and cutting block are arranged in a predetermined manner .
    • 用于整形外科手术的切割步骤中的切割导向仪器包括参考部件,该参考部件包括第一元件(26),该第一元件可相对于骨头以预定布置被附接或以其它方式对准,以及定位臂(30)。 本发明还包括切割块(28),其包括参考表面(34),所述参考表面可被切割工具接合以在切割步骤期间限定所述工具的位置和取向。 切割块还包括至少一个用于接收固定销以将切割块固定到骨上的固定孔(33)。 定位臂可以安装在参考表面上,使得参考部件和切割块以预定方式布置。
