Abstract:
1. A fastener that can be delivered through a tube for fixing a planar prosthetic component to an anatomical support, comprising: a single-piece structure that can be obtained by molding of a plastics material, and having at least one anchoring element adapted to engage the anatomical support, at least one immobilizing element that engages the planar prosthetic component to be fixed, and a linking rod that flexibly engages a zone of connection of the anchoring element located in approximately a middle of a length of the anchoring element and that flexibly engages a zone of connection of the immobilizing element located in approximately a middle of a length of the immobilizing element and the linking rod having a bulge located in the center of the linking rod separating an end that engages the zone of connection of the anchoring element and an end that engages the zone of connection of the immobilizing element; the linking rod being rectilinear and the zones of connection allowing the fastener to adopt at least three distinct configurations: a non-stressed mold-release configuration in which respective directions of an axis of the immobilizing element and of an axis of the anchoring element form between them, in the same plane having an axis of the linking rod, an internal angle of at least 90°; a configuration of maximum stress, doubled back on itself, by complete insertion of said fastener into the tube, in which the configurations of the anchoring element and the immobilizing element are folded toward the linking rod and toward one another; and are arranged end-to-end, and the linking rod axis extends parallel to the direction of the anchoring element axis and the immobilizing element axis, and a configuration of minimum stress in which the respective axes of the immobilizing element and the anchoring element form between them, in the same plane, an angle not greater than 90°.
