Abstract

"SISTEMA DE FIXAçãO ESPINHAL". Um sistema de fixação espinhal é provido, o qual, em um caso, inclui um membro de acoplamento tendo um membro de trava de came que é fixado contra translação ao longo do mesmo quando ele é girado com o giro do membro de trava de came, fazendo com que um membro alongado, como uma haste espinhal, seja empurrada descendentemente no membro de acoplamento para fixar a haste no mesmo. Em um outro aspecto, a haste é fixada contra um inserto de perfil baixo que se assenta em um recesso formado na cabeça de um membro de ancoragem se projetando do membro de acoplamento. O inserto tem uma superfície superior contra a qual a haste é fixada e que, em uma forma, é plana, para prover contato de linha contra a haste de modo a minimizar dano a mesma. Em uma outra forma, o membro de trava de came atua em came contra um membro de sujeição, acionando o mesmo descendentemente no membro de acoplamento para fixa a haste no mesmo.
