Con el fin de resolver los problemas técnicos existentes anteriormente, la invención proporciona un hueso artificial como se reivindica en la reivindicación 1.
Otras mejoras opcionales se establecen en las reivindicaciones 2 a 5.
Resultado ventajoso de la invención
En comparación con las tecnologías existentes, el resultado ventajoso de la invención es: utilizar hueso artificial para reemplazar el hueso original, establecer un pilar de soporte y una estructura de armazón porosa en 3D mientras tanto, el pilar de soporte se acopla al extremo que se conecta al hueso original para funcionar como soporte y fijación. Establecer la estructura de armazón porosa en 3D en la periferia del extremo de acoplamiento que se conecta al hueso original, para proporcionar espacio para la adhesión y el crecimiento de las células óseas, y para que la conexión entre el hueso artificial y el hueso original sea más estable.

Descripción detallada de la Invención
A continuación, se describe más detalladamente la invención en combinación con los dibujos y la realización.
Como se muestra en las Figs. 1 -3, un hueso artificial, que comprende hueso biónico, pilar de soporte y estructura de armazón porosa en 3D; el pilar de soporte y la estructura de armazón porosa en 3D están conectados al hueso biónico, la estructura de armazón porosa 3D se establece para cubrir el pilar de soporte. Se utiliza del hueso artificial para reemplazar el hueso original, a la vez que, se establece el pilar de soporte y la estructura de armazón porosa en 3D para fortalecer la conexión entre el hueso artificial y el hueso original y promover el crecimiento posterior de las células óseas.
El pilar de soporte del modelo de utilidad son dos columnas y el prisma entre dos columnas, la sección transversal de dicho prisma es rectangular, puede ser la parte de fijación al bruñir, moler o pulir el hueso biónico, también evita la rotación y el desplazamiento entre el pilar de soporte y el hueso original. Específicamente, el área de la sección transversal del prisma es menor que el área de la sección transversal de la columna. Dicho pilar de soporte puede entrar en el extremo de acoplamiento que se conecta al hueso original, la estructura de armazón porosa en 3D se establece para cubrir el extremo de acoplamiento que se conecta al hueso original.
La forma y el tamaño del poro de dicha estructura de armazón poroso en 3D en el modelo de utilidad se cambian según la necesidad real o la situación real del paciente.
El hueso biónico en el modelo de utilidad se fabrica de acuerdo con los datos en 3D del hueso original reemplazado, el pilar de soporte se fabrica de acuerdo con la inclinación del hueso original. Hay varios métodos de fabricación de hueso artificial: en el primer método, el hueso biónico, el pilar de soporte y la estructura de armazón porosa en 3D son una estructura integral. La estructura integral se imprime directamente mediante una impresora de metal 3D utilizando aleación de cobalto-cromo o aleación de titanio. En el segundo método, el hueso biónico, el pilar de soporte y la estructura de armazón porosa en 3D son una estructura integral, que se imprime directamente con una impresora de metal 3D utilizando una aleación de titanio y después se recubre con una aleación de cobalto-cromo en la superficie. En el tercer método, el pilar de soporte y la estructura de armazón porosa en 3D se conectan al hueso biónico respectivamente a través de una rosca de tornillo, es decir, primero se utiliza una aleación de cobalto-cromo para imprimir el hueso biónico mediante una impresora de metal 3D, después se utiliza una aleación de titanio para imprimir el pilar de soporte y la estructura de armazón porosa en 3D mediante una impresora de metal 3D, después se ensambla el pilar de soporte y la estructura de armazón porosa en 3D con hueso biónico respectivamente a través de una conexión roscada. En el cuarto método, el pilar de soporte y la estructura de armazón porosa en 3D se conectan al hueso biónico mediante sinterización, es decir, primero se utiliza una aleación de cobalto-cromo para imprimir el hueso biónico mediante una impresora de metal 3D, después se utiliza una aleación de titanio para imprimir el pilar de soporte y la estructura de armazón porosa en 3D mediante una impresora de metal 3D, luego se sinteriza el pilar de soporte y la estructura de armazón porosa en 3D en hueso biónico respectivamente.
Lo anterior es la descripción más detallada de la invención que se combina con la realización preferida, pero la invención no se limita únicamente a estas.
