Abstract

JUNçãO DINáMICA COMO PARTE DE UM SISTEMA DE ESTABILIZAçãO DA COLUNA; MéTODO PARA EXECUçãO DO SISTEMA; PARAFUSO DE PENDICULO E SISTEMA DINáMICO DE ESTABILIZAçãO DA COLUNA Dispositivos, sistemas e métodos de estabilização da coluna são providos de moda a incluir pelo menos um parafuso de pedículo, e pelo menos um mecanismo que suporte três níveis de autonomia rotacional com relação ao parafuso do pedículo . O mecanismo pode incluir um mecanismo universal de junção ou um mecanismo de junta articulada. O mecanismo dinâmico de junção é vantajosamente incorporado em um sistema de estabilização da coluna que inclui parafuso(s) adicional de pedículo, elementos esféricos e membros de soquete. Os parafusos de pedículo são revelados de modo a incluir um aro estendendo-se para cima, O aro pode incluir ranhuras que se estendem para baixo de modo a definir segmentos desviáveis entre as mesmas. O parafuso de pedículo pode incluir um conjunto de parafuso pré-carregados que está mantido em posição por interferência o que é vantajosamente formado em um conjunto de parafuso para prevenir o deslocamento do mesmo, por exemplo, durante o carregamento árido ou a colocação clinica do parafuso de pedículo. Quando um elemento esférico ou outra estrutura, por exemplo, um elemento de estabilização não-dinâmica, é posicionado ao redor do aro, a introdução de um conjunto de parafuso faz com que o desvio para o exterior dos segmentos que vão para cima dentro da engrenagem com o elemento esférico. Um anel de ruptura pode ser interposto entre o aro e o elemento esférico para facilitar o posicionamento entre os mesmos. Em uma configuração alternativa, um aro sem ranhura é empregado. Membros-guia afilados são revelados para o posicionamento adjacente para/ou em justaposição com a cabeça de um parafuso de pedículo. Um componente, por exemplo, um elemento esférico, pode ser avançado para dentro de um aro que se estende para cima a partir da cabeça de um parafuso de pedículo usando o membro-guia. Um arame-guia também pode ser empregado para guiar componentes ao parafuso de pedículo e/ou guiar o arame-guia dentro da posição. Os mecanismos de comunicação revelados podem incluir uma bainha de revestimento posicionada ao redor dos mesmos. A bainha de revestimento é fabricada a partir de um material que se adapta com relação aos movimentos dos membros de contato e apoio, enquanto apresenta um comportamento substancialmente inerte com relação ao contorno das estruturas anatómicas.DYNAMIC JOINT AS PART OF A COLUMN STABILIZATION SYSTEM; Method for the implementation of the system; PENDICULAR SCREW AND DYNAMIC COLUMN STABILIZATION SYSTEM Column stabilization devices, systems and methods are provided to include at least one pedicle screw, and at least one mechanism that supports three levels of rotational autonomy with respect to the pedicle screw. . The mechanism may include a universal joint mechanism or a pivot joint mechanism. The dynamic joining mechanism is advantageously incorporated into a column stabilization system that includes additional pedicle screw (s), ball elements and socket members. The pedicle screws are developed to include an upwardly extending rim. The rim may include downwardly extending grooves to define offset segments between them. The pedicle screw may include a preloaded screw assembly that is held in position by interference which is advantageously formed into a screw assembly to prevent displacement thereof, for example during arid loading or clinical screw placement. pedicle When a spherical element or other structure, such as a non-dynamic stabilizing element, is positioned around the rim, the introduction of a bolt assembly causes the outward deviation of the upward segments inside the gear with the spherical element. A snap ring may be interposed between the rim and the spherical element to facilitate positioning therebetween. In an alternative embodiment, a non-slotted rim is employed. Tapered guide members are revealed for adjacent positioning for / or juxtaposing with the head of a pedicle screw. A component, for example a spherical member, may be advanced into an upwardly extending rim from the head of a pedicle screw using the guide member. A guidewire may also be employed to guide components to the pedicle screw and / or guide the guidewire into position. The disclosed communication mechanisms may include a sheath sheath positioned around them. The sheath is made of a material that conforms to the movements of the contact and support members, while exhibiting substantially inert behavior with respect to the contour of the anatomical structures.
