ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
En la actualidad la principal causa de amputaciones de miembros inferiores es la diabetes mellitus, así como accidentes en trenes, automovilísticos, en fabricas ó con maquinaría agrícola, en el caso de la diabetes mellitus a pesar de los grandes avances en la fisiopatología de esta enfermedad, los índices de amputación permanecen elevados.At present, the main cause of lower limb amputations is diabetes mellitus, as well as accidents in trains, cars, factories or with agricultural machinery, in the case of diabetes mellitus despite the great advances in the pathophysiology of this disease. , amputation rates remain high.
Por lo tanto cuando a una persona se le amputa un miembro es practica común instalar un miembro artificial, los hay de muchos tipos, siendo la gran mayoría, miembros externos que se aplican sobre un muñón previamente cicatrizado y que se forma cuando se realiza la amputación con piel de la misma persona a la que se le realizó la amputación, incluso se manejan niveles de amputación no estandarizados y cobertura del muñón con colgajos libres, el fin de usar una prótesis en una extremidad superior ó inferior amputada es la de conservar la mayor estabilidad y función de dicho miembro en lo que sea posible con el uso de la prótesis y disminuir al máximo el trabajo físico necesario para la deambulación e incorporación a una vida "normal".Therefore, when a person is amputated a member it is common practice to install an artificial limb, there are many types, the vast majority, external members that are applied on a previously healed stump and that is formed when the amputation is performed With skin of the same person who had the amputation performed, even standardized amputation levels and coverage of the stump with free flaps are managed, the purpose of using a prosthesis on an amputated upper or lower limb is to preserve the largest stability and function of said member as far as possible with the use of the prosthesis and minimize the physical work necessary for ambulation and incorporation into a "normal" life.
Como se dijo anteriormente uno de los principales problemas es el acoplamiento de la prótesis en el muñón practicado en dicho miembro amputado, en donde los métodos de acoplamiento son por los general unidades plásticas diseñadas para cubrir el muñón y posteriormente reforzarse en el miembro en donde se coloca dicha prótesis, este método comúnmente usado provoca serias repercusiones para el portador, tanto físicas como psicológicas. El problema aquí presentado es precisamente en las repercusiones tanto físicas como psicológicas que provoca el uso de una prótesis como las mencionadas anteriormente, ya es un aparato que puede provocar diversos malestares tales como heridas, llagas, etc., además de proporcionar un sentimiento de desconfianza en el portador entre otras cosas.As previously stated, one of the main problems is the coupling of the prosthesis in the stump practiced in said amputated limb, where the coupling methods are by the general plastic units designed to cover the stump and subsequently reinforce in the limb where place said prosthesis, this commonly used method causes serious repercussions for the wearer, both physical and psychological. The problem presented here is precisely in the physical and psychological repercussions caused by the use of a prosthesis such as those mentioned above, it is already a device that can cause various discomforts such as wounds, sores, etc., in addition to providing a feeling of distrust in the carrier among other things.
Con la finalidad de suprimir estos y inconvenientes sé pensó en el desarrollo de la invención "Prótesis con Punto de Apoyo Esquelético para Extremidades Superiores e Inferiores" que se pretende proteger por medio de la presente solicitud, pues se trata de una prótesis que usa como apoyo los huesos de la extremidad amputada, brindando con ello una disminución considerable de los problemas físicos ó psicológicos ocasionados por el uso de las prótesis convencionales.In order to eliminate these and inconveniences, the development of the invention "Prosthetic Skeletal Support Point for Upper and Lower Extremities" was intended to be protected by means of the present application, since it is a prosthesis used as support the bones of the amputated limb, thereby providing a considerable decrease in physical or psychological problems caused by the use of conventional prostheses.

Como se ha dicho anteriormente esta "Prótesis con Punto de Apoyo Esquelético para Extremidades Superiores e Inferiores" basa su funcionamiento en que el tornillo de inserción (1.1) una vez que la extremidad superior ó inferior ha sido amputada durante la cirugía, se procede a maquinar el hueso por su parte central formándole la rosca que recibirá al tornillo de inserción (1.1) una vez que la rosca esta formada se introduce algún material que puede ser grasa inerte (2.4) ó materiales adecuados para este hecho de manera que la medula (2.3) no se mezcle con el tomillo de inserción (1.1), una vez instalado el tomillo de inserción (1.1) la prótesis se complementa con los dispositivos existentes tal como se muestra en la fig. 4, que se conforman mediante un soporte (4.2) con rosca (4.3) que recibe al tomillo de inserción (1.1), un extensor (4.1) para ajustar la altura necesaria de la prótesis, un soporte (4.4) asegurado al extensor (4.1) mediante un tornillo (4.5) y en dicho soporte (4.4) se incorpora en este caso de presentación el pie artificial, que si fuera colocada esta prótesis en una extremidad superior sería una mano artificial.(1.3) welded together and the thread can be made in a single body and machined to receive the insertion screw (1.1), in this nut a thread (1.31) has been made that receives an alien type screw (1.6) that secures the insertion screw (1.1), in correspondence with the lower part of the nut (1.3) a stop washer (1.4) has been incorporated to support the stump (fig. 3 and 3.2) that is formed with the soft tissue (3.1 ) of the limb (fig. 3), likewise a plastic cover (3.3) has been added as a support for the stump, said cover (3.3) is positioned by a nut (3.4) secured by a screw (3.5). As previously stated, this "Skeletal Support Point Prosthesis for Upper and Lower Extremities" bases its operation on the fact that the insertion screw (1.1) once the upper or lower limb has been amputated during surgery, it is then machined the bone through its central part forming the thread that will receive the insertion screw (1.1) once the thread is formed, some material that can be inert grease (2.4) or materials suitable for this fact is introduced so that it is medulled (2.3 ) Do not mix with the insertion thyme (1.1), once the insertion thyme (1.1) is installed, the prosthesis is complemented with the existing devices as shown in fig. 4, which are formed by a support (4.2) with thread (4.3) that receives to the insertion thyme (1.1), an extender (4.1) to adjust the necessary height of the prosthesis, a support (4.4) secured to the extender (4.1 ) by means of a screw (4.5) and in this support (4.4) the artificial foot is incorporated in this case, which if this prosthesis were placed in an upper limb would be an artificial hand.
Por todo lo dicho anteriormente se puede afirmar que estas y otras características no han sido logradas por ninguna otra prótesis y reúne en si las características de tener su apoyo en la estructura ósea evitando con ello la gran cantidad de problemas por el uso de las prótesis convencionales. For all the above, it can be affirmed that these and other characteristics have not been achieved by any other prosthesis and brings together the characteristics of having their support in the bone structure, thereby avoiding the large number of problems due to the use of conventional prostheses. .
