Abstract

"ENDOPRóTESE NãO CONVENCIONAL PROXIMAL DE TìBIA COM COMPONENTE INTERCONDILIANO DE RESSECçãO MìNIMA COM ROTAçãO NA TìBIA". Refere-se a presente Patente de Invenção a Endoprótese Não Convencional Proximal de Tíbia Com Componente Intercondiliano De Ressecção Mínima Com Rotação Na Tíbia, (1), caracterizada por ser constituída por uma prótese em base a três componentes, o inferior (2) com as funções de rotação, um intermediário (3) com as funções de rotação na parte inferior e de articulação na parte superior e o componente superior (4) que permite a articulação por meio de dobradiça com haste intracondiliano, o componente inferior (2) é formado por um corpo (5) de poliuretano, possui na sua base, uma haste (6) metálica com ranhuras longitudinais e na parte superior uma placa (7) com dois pinos que permitem e limitam a rotação, a qual é realizada pelo pino de maior tamanho (8) e a limitação é conseguida por meio pelo pino de menor tamanho (9), o componente intermediário (3) é formado por um corpo de poliuretano que penetra e encaixa, dada a existência de orifício localizado na base, no pino de maior tamanho (8) e efetua a rotação prevista, limitada pelo pino de menor tamanho (9), dispõe de bloco (10) com orifício (11) transversal para permitir a passagem de uma haste (12) que fixará o componente superior (4) ao componente intermediário (3), o componente superior (4) é formado por uma peça metálica tipo alavanca com à parte inferior formando uma dobradiça (13) que encaixará no bloco (10) e será prendido pela haste (12) e seguro pelo pino (14) colocado sob pressão numa das laterais, a parte superior deste componente (4) possui formato de asa com ponta arredondada."NON-CONVENTIONAL TYBIA ENDOPROSTHESIS WITH INTERCONDILE COMPONENT WITH MINIMUM RESICTION WITH ROTATION IN TIBIA". The present Invention Patent refers to the Non-Conventional Proximal Tibial Endoprosthesis With Intercondylar Component With Minimum Resection With Rotation In The Tibia, (1), characterized by consisting of a prosthesis based on three components, the lower (2) with the rotation functions, an intermediate (3) with the rotation functions at the bottom and articulation at the top and the upper component (4) that allows articulation by means of a hinge with an intracondylar stem, the lower component (2) is formed by a polyurethane body (5), it has, at its base, a metal rod (6) with longitudinal grooves and at the top a plate (7) with two pins that allow and limit the rotation, which is performed by the largest pin size (8) and the limitation is achieved by means of the smallest pin (9), the intermediate component (3) is formed by a polyurethane body that penetrates and fits, given the existence of a localized hole at the base, on the largest pin (8) and performs the predicted rotation, limited by the smallest pin (9), it has a block (10) with a transverse hole (11) to allow the passage of a rod (12) that will fix the upper component (4) to the intermediate component (3), the upper component (4) is formed by a lever-type metal part with the lower part forming a hinge (13) that will fit in the block (10) and will be secured by the rod (12) and secured by the pin (14) placed under pressure on one of the sides, the upper part of this component (4) has a wing shape with a rounded tip.
