Abstract

SE PRESENTA UN APARATO AUXILIAR ELECTROMAGNETICO PARA TRATAMIENTO TERMICO DESTINADO A SU USO CON UN ENDOSCOPIO, PARA DOTAR A ESTE DE LA CAPACIDAD DE TRATAMIENTO TERMICO ELECTROMAGNETICO. EL APARATO AUXILIAR COMPRENDE UNA PARTE DE MANGO Y UNA PARTE ALARGADA CONECTADA A ELLA Y DIMENSIONADA PARA QUE SE INSERTE AL MENOS PARCIALMENTE EN EL CANAL DE TRABAJO DE UN ENDOSCOPIO. LA PARTE ALARGADA INCLUYE AL MENOS UN TUBO DE SUMINISTRO QUE TIENE UNA PARTE DE MEMORIA QUE COMPRENDE UN MATERIAL CON PROPIEDADES DE MEMORIA DE LA FORMA Y QUE DEFINE NORMALMENTE UNA CONFIGURACION CURVADA. EL TUBO DE SUMINISTRO ES LONGITUDINALMENTE MOVIL CON RELACION A LA PARTE DEL MANGO PARA EXTENDER LA PARTE DE MEMORIA MAS ALLA DEL CANAL DE TRABAJO DEL ENDOSCOPIO, DE MANERA QUE LA PARTE DE MEMORIA ASUMA LA CONFIGURACION NORMAL CURVADA DE LA MISMA. DENTRO DEL TUBO DE SUMINISTRO SE DISPONE UNA SONDA ELECTROMAGNETICA, LA CUAL PUEDE MOVERSE LONGITUDINALMENTE CON RELACION A ESTE PARA EXTENDERSE MAS ALLA DEL TUBO DE SUMINISTRO HASTA EL INTERIOR DEL TEJIDO. LA SONDA ELECTROMAGNETICA ESTA ADAPTADA PARA SEGUIR LA CONFIGURACION CURVADA DE LA PARTE DE MEMORIA DEL TUBO DE SUMINISTRO, A FIN DE DESPLEGARSE ANGULARMENTE CON RESPECTO AL ENDOSCOPIO. SE MONTA EN LA PARTE DEL MANGO UN MIEMBRO DE CONTROL GIRATORIO QUE SE CONECTA OPERATIVAMENTE CON EL TUBO DE SUMINISTRO. ESTE MIEMBRO DE CONTROL ES GIRATORIO PARA MOVER EL TUBO DE SUMINISTRO ENTRE UNA PRIMERA POSICION CONTRAIDA Y UNA SEGUNDA POSICION AVANZADA. TAMBIEN SE MONTA EN LA PARTE DEL MANGO UN DISPOSITIVO DE ACCIONAMIENTO QUE SE CONECTA OPERATIVAMENTE CON LA SONDA ELECTROMAGNETICA. EL DISPOSITIVO DE ACCIONAMIENTO SE MUEVE PARA EXTENDER LA PARTE DEL EXTREMO DE LA SONDA MAS ALLA DEL TUBO DE SUMINISTRO. LA INVENCION TAMBIEN SE REFIERE A UNA COMBINACION DE UN ENDOSCOPIO Y UN DISPOSITIVO DE TRATAMIENTO TERMICO AUXILIAR. SE PRESENTA ASIMISMO UN METODO PARA EL TRATAMIENTO TERMICO DE LOS TEJIDOS.
