Patent number: 11364090Abstract: 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.Type: GrantFiled: March 23, 2020Date of Patent: June 21, 2022Assignee: TERUMO CARDIOV ASCULAR SYSTEMS CORPORATIONInventor: Takeshi Tsubouchi

Patent number: 11351003Abstract: A head frame apparatus is secured to a human head during maxillofacial surgery and includes devices to easily position and secure an endotracheal (breathing) tube and an anesthesia delivery circuit for the patient that reduces the likelihood that the flow of oxygen through the tube is restricted thereby reducing the risk of severe injury or death. The head frame apparatus also includes a removable reference indicator, which may be easily attached and removed while identifying a reference point of the patient's face. Also the reference indicator includes a universal joint and pointer with an attached ruler. A transport apparatus positions multiple preset reference indicators and allows for preoperative transportation and removal, while protecting the preset reference indicators from inadvertent adjustment. A bendable reference indicator used in an articulator for preoperative modeling allows for easily identifying reference points in a cast model.Type: GrantFiled: July 1, 2016Date of Patent: June 7, 2022Inventor: Martin Chin
