    Abstract: A fail-safe attachment is provided for coupling an exoskeletal prosthesis to a patient limb having a bone anchored mounting post with an external fixation structure (1). The fail-safe attachment comprises a first component (2) adapted for connection to the fixation structure, and a second component (3) adapted for connection to the prosthesis. A safety release mechanism is provided normally retaining the prosthesis in a rigid substantially motion-free interconnected relation to the fixation structure, said safety release mechanism responding to a force overload condition to permit relative movement between the prosthesis and the fixation structure. The safety release mechanism comprises a bending force release mechanism responsive to a bending force overload condition to permit the separation of the second component (3) relative to said first component (2). The bending force release mechanism comprises a plurality of spring loaded jaws (37) adapted to engage a complementary portion (12) of the other component, the jaws (37) being pivotable in an over-centre spring configuration between a first position in which they engage the complementary portion (12) to secure the first and second components one to the other, and a second position in which the first and second components are able to separate.

    Abstract translation: 提供故障安全附件,用于将外骨骼假体联接到具有骨锚固安装柱的患者肢体与外部固定结构(1)。 故障安全附件包括适于连接到固定结构的第一部件(2)和适于连接到假体的第二部件(3)。 提供了一种安全释放机构,其通常将假体保持在与固定结构相关联的刚性基本上无运动的互连关系中,所述安全释放机构响应于力过载状态以允许假体和固定结构之间的相对运动。 安全释放机构包括响应于弯曲力过载状态以允许第二部件(3)相对于所述第一部件(2)分离的弯曲力释放机构。 弯曲力释放机构包括适于接合另一部件的互补部分(12)的多个弹簧加载的夹爪(37),所述夹爪(37)可以以中心以上的弹簧构型在第一位置之间枢转,在第一位置 接合所述互补部分(12)以将所述第一和第二部件固定到另一个部分,以及第二部件和第二部件能够分离的第二位置。
