Abstract

Implante médico (1) destinado a permitir la fusión ósea entre un primer hueso (P2) y un segundo hueso (P1), dicho implante comprendiendo una primera parte (20), de forma globalmente alargada y que presenta un eje longitudinal A, destinada a ser introducida en el interior del primer hueso y que comprende primeros medios de fijación (24) de dicho implante en el interior de dicho primer hueso, y una segunda parte (30), de forma igualmente globalmente alargada y que presenta un eje longitudinal B, destinada a ser introducida en el interior del segundo hueso y que comprende segundos medios de fijación (34) de dicho implante en el interior de dicho segundo hueso, dichas partes primera y segunda (20, 30) estando unidas entre ellas por un núcleo central (40), caracterizado por que dicho núcleo central es un sólido macizo cuya sección en corte por un plano perpendicular a dicho eje longitudinal A presenta sensiblemente una forma de estrella de por lo menos tres brazos (41, 42, 43), dicha primera parte presentando por lo menos tres patillas (21, 22, 23), cada patilla extendiéndose sensiblemente según dicho eje longitudinal A, a partir del extremo libre (41a, 42a, 43a) de uno de los tres brazos de dicho núcleo central.

destinada a ser introducida por ejemplo en el interior del canal medular de una primera falange y la segunda parte, igualmente de forma alargada, del implante según la invención, está destinada a ser introducida en el interior del canal medular de la segunda falange, adyacente a la primera. Gracias a su estructura específica, en particular gracias a la presencia de tres patillas en la primera parte del implante, cada una de ellas extendiéndose a partir de un brazo del núcleo central macizo, el implante según la invención asegura una estabilidad perfecta en las tres direcciones del espacio, del conjunto de la primera falange, la segunda falange y el implante y esto en la posición deseada por el cirujano en el momento de la implantación. Además, el núcleo central sólido macizo del implante según la invención asegura a la vez una rigidez y una flexibilidad del implante, que permite una colocación fácil del implante en su sitio y un mantenimiento fiable del conjunto del primer hueso, el segundo hueso y el implante en una posición determinada.
Según la presente solicitud, se entiende por "forma de estrella de por lo menos tres brazos", una forma que tiene un punto de unión a partir del cual se extienden, sensiblemente radialmente, por lo menos tres brazos, dichos brazos estando separados unos de los otros por ángulos regulares o no. Por ejemplo, en una forma de realización, dicha sección en corte de dicho núcleo central presenta una forma en T: en un caso de este tipo, los tres brazos de la T están separados entre ellos ángulos diferentes, a saber dos ángulos de 90° y un ángulo de 180°. En otra forma de realización, dicha sección en corte de dicho núcleo central presenta una forma en Y. En otras formas de realización, la sección en corte del núcleo central presenta una forma de estrella de más de tres brazos, por ejemplo de cuatro o de cinco brazos.
El núcleo central del implante según la invención es un sólido macizo: así, el punto de unión de la estrella está constituido por material. En una forma de realización, dicho implante es mono bloque. El implante según la invención puede estar formado de un material escogido entre las poliéter éter cetonas (PEEK), el titanio, el acero inoxidable, los ácidos polilácticos y sus mezclas. Por ejemplo, el implante según la invención puede ser reabsorbible biológicamente o no.
El implante según la invención por ejemplo pueden estar realizado por moldeo por inyección o incluso por mecanización.
En una forma de realización, dichas patillas presentan globalmente la forma de un paralelepípedo alargado, por lo menos una patilla presenta una sección transversal reducida al nivel de su unión con el núcleo central. De preferencia, las tres patillas presentan, cada una, una sección transversal reducida al nivel de su unión con el núcleo central. Una forma de este tipo de realización permite conferir al implante una elasticidad y una flexibilidad que le permiten colocarlo fácilmente en su sito. Además, por el hecho de la estructura maciza del núcleo central, el implante conserva una rigidez que le permite asegurar una buena estabilidad del conjunto del primer hueso, el segundo hueso y el implante en el lugar de implantación.
En una forma de realización, dicha segunda parte presenta por lo menos dos patas que se extienden según el eje longitudinal B a partir de dicho núcleo central. Alternativamente, dicha segunda parte presenta tres patas que se extienden según el eje longitudinal B a partir de dicho núcleo central.
En una forma de realización, la sección en corte de dicho núcleo central por un plano perpendicular a dicho eje longitudinal B presenta sensiblemente dicha forma de estrella de por lo menos tres brazos, cada una de dichas patas extendiéndose sensiblemente según dicho eje longitudinal B a partir del extremo libre de uno de los brazos de dicho núcleo central.
Una forma de realización de este tipo permite reforzar la estabilidad en las tres direcciones del espacio del conjunto del primer hueso, el segundo hueso y el implante, en la posición deseada por el cirujano, una vez que el implante según la invención está implantado y que los dos huesos que se van a soldar están reunidos uno al otro.
En una forma de realización, dichas patas presenta globalmente la forma de un paralelepípedo alargado, cada pata presenta una sección transversal reducida al nivel de su unión con el núcleo central. Como se ha visto anteriormente, una forma de realización de este tipo permite conferir al implante una elasticidad y una flexibilidad que permiten colocarla fácilmente en su sitio. Además, por el hecho de la estructura maciza del núcleo central, el implante conserva una rigidez que le permite asegurar una buena estabilidad del conjunto del primer hueso, el segundo hueso y el implante en el lugar de implantación.
En una forma de realización, dichos primeros medios de fijación comprenden muescas de anclaje situadas sobre dichas patillas. Por ejemplo, estas muescas de anclaje están situadas sobre las caras exteriores de los paralelepípedos que forman estas patillas, a fin de que estas últimas se fijen en el interior del hueso en el cual están introducidas. Igualmente, los segundos medios de fijación pueden comprender muescas de anclaje situadas sobre dichas patas, por ejemplo sobre las caras exteriores de los paralelepípedos que forman dichas patas a fin de que estas últimas se fijen en el interior del hueso en el cual se introducen. Las muescas de anclaje presentan de preferencia aristas dirigidas hacia el núcleo central a fin de comprimir cada hueso en dirección al otro hueso, contra el cual está reunido, en el momento en el que el implante según la invención se implanta.
