Abstract

REFORÇO DE FIXAÇÃO EXTERNA APERFEIÇOADO. A presente revelação refere-se a um reforço de fixação externa aperfeiçoado que compreende: - um corpo alongado que compreende um primeiro e um segundo eixo tubular vazado; - conectores opostos respectivamente acoplados a uma porção de extremidade do primeiro ou do segundo eixo e cada um incluindo uma articulação esférica; - um eixo tendo um diâmetro interno que seja ligeiramente maior que o diâmetro externo do outro eixo para hospedar internamente o outro eixo em uma maneira deslizante e telescópica; - os ditos primeiro e segundo eixos do reforço sendo concebidos por um material plástico radiolucente sintético; - um elemento de fita proporcionado em proximidade às extremidades opostas do primeiro e segundo eixos para proporcionar uma ação de preensão rápida que interrompe o deslizamento telescópico de um eixo dentro do outro eixo; - um elemento de fixação manualmente operado atuando no elemento de fita para exercer a dita ação de preensão rápida ? uma manga proporcionada ao redor da porção central do reforço onde o primeiro e o segundo eixos se sobrepõem; - uma banda de fita ao redor da dita manga e incluindo porções de preensão opostas e viradas, sendo que as ditas porções de preensão são conectadas por um conector roscado. Revela-se, também, um sistema de fixação incluindo pelo menos um primeiro e um segundo anel de fixação e/ou pelo menos um arco de fixação interconectado por ao menos um dos reforços de fixação anteriores.
