Abstract

"GUIA CONJUGADO DE OSTEOTOMIA PARA ARTROPLASTIA TOTAL DE JOELHO". Caracterizado por ser por ser constituído de diversos instrumentos conjugados de modo a acoplar ou conjugar em um mesmo conjunto, o guia de corte tibial à porção femoral (distrator femoral), a qual se apóia sobre a superfície de corte dos cóndilos distais do fêmur, o guia de corte tibial, uma vez acoplado ao distrator, não apresenta movimentos laterais, mas sim somente movimentos axiais, garantindo assim um corte tibial perfeitamente paralelo ao corte dos condilos femorais distais e garantindo também um espaço de extensão retangular, ainda pode-se acoplar ou conjugar à porção femoral do guia, distratores articulares que permitem um perfeito balanço ligamentar, simultaneamente ao posicionamento adequado no membro inferior, no eixo mecânico, além de manter uma escala de leitura no suporte do guia de corte tibial, que permite a mensuração do espaço de extensão, feita já com o joelho balanceado e com superfícies de corte femoral e tibial rigorosamente paralelos, ainda, em um mesmo conjunto, a bandeja tibial (que se apóia sobre a superfície de corte tibial) ao suporte do guia de cortes femorais múltiplos, o suporte do guia de cortes femorais múltiplos, uma vez acoplado à bandeja tibial, não apresenta movimentos laterais, mas sim somente movimentos axiais, garantindo assim um corte dos cóndilos posteriores e anteriores do fêmur, perfeitamente paralelo ao corte da tíbia proximal, e garantindo assim um espaço de flexão retangular e também uma rotação externa do fêmur própria para o joelho em questão e não com valores fixos de rotação externa ou por estimativas a olho nu como ocorre nos sistemas convencionais, por fim acopla-se à porção tibial (bandeja tibial) do guia, distratores articulares que permitem um perfeito balanço ligamentar, simultaneamente ao posicionamento adequado no membro inferior, além de manter uma escala de leitura ao suporte do guia de corte tibial, que permite a mensuração do espaço de flexão e que permite calibrar o espaço de flexão para que tenha o mesmo valor do espaço de extensão, o que garante um espaço de flexão e extensão de mesma magnitude feita já com o joelho balanceado e de superfícies de corte femoral e tibial rigorosamente paralelos."JOINT OSTEOTOMY GUIDE FOR TOTAL KNEE ARTHROPLASTY". It is characterized by being composed of several instruments conjugated in order to couple or conjugate in the same set, the tibial cutting guide to the femoral portion (femoral distractor), which rests on the cutting surface of the distal condyles of the femur. The tibial section guide, once coupled to the distractor, has no lateral movements, but only axial movements, thus ensuring a tibial section perfectly parallel to the cut of the distal femoral condyles and also ensuring a rectangular extension space, can still be coupled or conjugate to the femoral portion of the guide, articular distractors that allow a perfect ligament balance, simultaneously with proper positioning in the lower limb, on the mechanical axis, besides maintaining a reading scale in the support of the tibial section guide, which allows the measurement of the already done with the knee balanced and with strictly parallel femoral and tibial Since the tibial tray (which rests on the tibial cutting surface) to the multiple femoral section guide holder, the multiple femoral section guide holder, once coupled to the tibial tray, has no lateral movements. but only axial movements, thus ensuring a cut of the posterior and anterior condyles of the femur, perfectly parallel to the cut of the proximal tibia, thus ensuring a rectangular flexion space and also an external rotation of the femur suitable for the knee in question and not with fixed values of external rotation or by estimates with the naked eye as in conventional systems, finally couplers to the tibial portion (tibial tray) of the guide, articular distractors that allow a perfect ligament balance, simultaneously with proper positioning in the lower limb, besides maintaining a reading scale to the tibial section guide support, which allows the measurement of the flexion space and that allows It allows to calibrate the flexion space to the same value as the extension space, which guarantees a flexion and extension space of the same magnitude already done with the knee balanced and of strictly parallel femoral and tibial cutting surfaces.
