    • A surgical spacer comprising first and second hollow support members, a flexible container, and a compressible material disposed in the container is disclosed. The first and second support members each have an exterior and an interior cavity. The exteriors of the first and second support members are affixed together and the interior cavities of the first and second support members are connected via a connecting opening. The container is disposed in the interior cavities and extends through the connecting opening. In addition, the container is substantially impermeable to the compressible material. The first and second support members are more rigid than the flexible container. A combination of the first and second support members controls the shape of the flexible container, with the compressible material disposed therein, in response to a compressive load applied to an exterior of the spacer.
    • 公开了一种包括第一和第二中空支撑构件的外科间隔件,柔性容器和设置在容器中的可压缩材料。 第一和第二支撑构件各自具有外部和内部空腔。 第一和第二支撑构件的外部固定在一起,并且第一和第二支撑构件的内部空腔经由连接开口连接。 容器设置在内部空腔中并延伸穿过连接开口。 此外,容器基本上不可渗透到可压缩材料。 第一和第二支撑构件比柔性容器更刚性。 响应于施加到间隔件的外部的压缩载荷,第一和第二支撑构件的组合控制柔性容器的形状,其中可压缩材料设置在其中。
