  • Patent number: 11364090
    Abstract: A reusable flexible arm stabilizes tissues during surgical procedures. The stabilizer arm switches between a flexible state for conforming to a desired curvature and a rigid state for maintain a desired positioning. A suspension length provided by the stabilizer arm is also adjustable. The arm has an articulating portion with successive articulating links each having a central passage. A length adjustable portion has successive length-adjustable links each having a central passage. A tension cable extends through the central passages between a proximal one of the length-adjustable links and a distal one of the articulating links. A base member captures the length-adjustable links at a position corresponding to a desired extension length of the arm. A control mechanism is movable between a retracted position and an extended position to selectably separate the captured length-adjustable links, thereby adjusting a tension in the tension cable and a rigidity of the stabilizer arm.
