Summary:abstract a length-adjustable im nail system includes a telescoping im nail with proximal and distal bodies. an inner magnet within the proximal body is connected to a threaded rod which, in turn, is connected to the distal body. the threaded rod passes through a threaded block which is connected to the proximal body. the position of the distal end of the threaded rod is fixed with respect to the distal body, but may rotate freely within this fixed position. an actuator is also disclosed that includes a pair of rotating magnets disposed in an angular relationship with each other and the axis of the im nail and the patient's limb. rotation of these outer magnets in the same direction results in rotation of the inner magnet and threaded rod and a telescoping axial movement of the threaded block and proximal body with respect to the distal body. tradução resumo patente de invenção: "prego im telescópico e mecanismo de atuação". trata-se de um sistema de prego im de comprimento ajustável inclui um prego im telescópico com corpos proximal e distal. um ímã interno no corpo proximal é conectado a um bastão rosqueado que, por sua vez, é conectado ao corpo distal. o bastão rosqueado passa através de um bloco rosqueado que é conectado ao corpo proximal. a posição da extremidade distal do bastão rosqueado é fixada em relação ao corpo distal, mas pode girar livremente nessa posição fixada. um atuador também é apresentado, o qual includes um par de ímãs giratórios dispostos em uma relação angular um em relação ao outro e o eixo geométrico do prego im e o membro do paciente. a rotação desses ímã externos na mesma direção resulta na rotação do ímã interno e do bastão rosqueado e um movimento axial telescópico do bloco rosqueado e corpo proximal em relação ao corpo distal. 19757931v1 19757931v1 A length-adjustable IM nail system includes a telescoping IM nail with proximal and distal bodies.
