Abstract

An external fixation component includes two capture members adapted to capture independently a first and a second element of an external fixation system. A rotation member is provided between the two capture members, coupled to both capture members such that the coupling allows the two capture members to rotate about three axes relative to each other. Each capture member comprises a central locking screw extending therethrough and defining a longitudinal axis of the associated capture member. The rotation member comprises two rotation blockers, each blocker providing one interface surface adapted to be in contact with a complementary interface surface of one of the capture members, each blocker further provides a surface opposite to the interface surface comprising an inner cylindrical surface. The rotation member comprises a central disc element forming a rolling surface as complementary surface to the inner cylindrical surface of the corresponding rotation blocker. The rotation member comprises two nuts, wherein each nut is associated to one locking screw of a corresponding capture member. Each locking screw of a capture member extends through the corresponding rotation blocker a…
