Abstract

LA PROTESIS DE VASO EFECTUADA EN LA UNION DE CADENAS TIENE LA FORMA DE UN TUBO FLEXIBLE RECTO O RAMIFICADO CON UNA SUPERFICIE LISA O A MODO DE LAZOS EN UNA O AMBAS PARTES. LA PROTESIS SE REALIZA DE FIBRAS SINTETICAS, POR EJEMPLO POLIESTER. SEGUN LA CONSTRUCCION SE COMPONE LA PROTESIS DE VASO DE DOS PARES DE SEGMENTOS DE LAS MISMAS LONGITUDES (1) DE FORMA CUADRADA, QUE POR UNA PARTE ESTAN FORMADOS DE HILOS LISOS Y / O TEXTURADOS EN EL SISTEMA BASICO CON UN ELEVADO EFECTO DE CONTRACCION Y POR OTRA PARTE DE HILOS LISOS Y / O TEXTURADOS DEL SISTEMA DE COMPRESION CON UN BAJO EFECTO DE CONTRATACION, CON LO QUE LOS HILOS DEL SISTEMA DE BASE UNEN EN TRICOT Y LOS HILOS DEL SISTEMA DE COMPRENSION EN TEJIDO. LOS DOS PARES DADOS DE SEGMENTOS (1) LONGITUDINALES, QUE SE REPRESENTAN EN LAS FIG. 2 DE MODO SE SITUAN DOS SEGMENTOS (1) UNO JUNTO A OTRO Y BAJO ESTOS SEGMENTOS (1) SE LLEVA EL SEGUNDO PAR DE SEGMENTOS LONGITUDINALES (1), ESTAN CONECTADOS UNO CON OTRO LOS SEGMENTOS DE TAL MODO QUE RESPECTA A LAUNION, QUE SE FORMA UNA PROTESIS DE VASO QUE SE DISTRIBUYE EN DOS RAMAS. LA UNION DE AMBOS PARES DE SEGMENTOS LONGITUDINALES (1) SE LLEVA A CABO MEDIANTE PIES DE MALLA (2) ENTRECRUZADOS CONTRAPUESTOS QUE SE PRODUCEN DE TRES HILOS LISOS Y/O TEXTURADOS DEL SISTEMA DE CONEXION, CON LO QUE PARA LA CONEXION SIMULTANEAMENTE SEGUN LA FIG. 2 EN EL SEGMENTO DE LAS DOS RAMAS DE PROSTESIS SE UTILIZAN DOS VARILLAS DE RED DE BORDE DE CADA SEGMENTO (1) LONGITUDINAL Y EN EL SEGMENTO DEL DIAMETRO TOTAL DE PROTESIS LAS TRES VARILLAS DE RED DE BORDE DE CADA SEGMENTO LONGITUDINAL (1). LOS SISTEMAS DE HILOS DE UNION CONTIENEN CON VENTAJA MENOS HILOS PARCIALES DEL SISTEMA DE BASE Y/O CONTRACCION.
