Abstract

<B>"SISTEMA MICRO-MECâNICO"<D>. é construído um sistema micro-mecânico para procedimentos médicos na forma básica de um catéter (103), possuindo uma extremidade distal, para inserção e manipulação dentro de um corpo, e uma extremidade proximal, permitindo a um usuário controlar a manipulação da extremidade distal dentro do corpo. Um cabo de fibra-ótica é posicionado dentro do catéter, possuindo uma extremidade distal adjacente à extremidade distal do catéter, e uma extremidade proximal para acoplamento externo de energia luminosa laser. Uma micro-garra (70) é conectada à extremidade distal do catéter, proporcionando capturar ou liberar um objeto dentro do corpo. Um conversor de luz laser em potência mecânica está conectado para receber luz laser da extremidade distal do cabo de fibra ótica e para atuar mecanicamente na micro-garra.
