Claims (12)
- REIVINDICAÇÕES1. Componente de endoprótese que compreende um corpo (23) predefinindo a forma do componente de endoprótese (17) e no qual, nas porções de superfície (22) com as quais o componente de endoprótese no estado implantado fica em contato com o tecido humano, o corpo (23) é coberto com uma camada externa (25) que compreende um nitreto, um oxinitreto ou um óxido com base em um metal refratário, a camada externa (25) contendo prata e/ou cobre caracterizado pelo fato de que uma camada intermediária (24) é disposta entre a camada externa (25) e o corpo (23) e sendo que partes da camada intermediária (24) ficam acessíveis a partir do exterior.
- 2. Componente de endoprótese de acordo com a reivindicação 1, caracterizado pelo fato de que a camada intermediária (24) é composta de prata, cobre e/ou ouro.
- 3. Componente de endoprótese de acordo com a reivindicação 1 ou 2, caracterizado pelo fato de que a camada externa (25) é interrompida, e sendo que as interrupções ocupam uma proporção da área de superfície de pelo menos 20%, de preferência de pelo menos 40%, mais preferivelmente de pelo menos 60%.
- 4. Componente de endoprótese de acordo com qualquer uma das reivindicações 1 a 3, caracterizado pelo fato de que a camada externa (25) é porosa.
- 5. Componente de endoprótese de acordo com qualquer uma das reivindicações 1 a 4, caracterizado pelo fato de que a camada externa (25) tem uma microestrutura ou nanoestrutura com picos distintos (26).
- 6. Método para a produção de um componente de endoprótese (17), caracterizado pelo fato de que compreende as seguintes etapas:a. tornar disponível um corpo (23) que predefine a forma do componente de endoprótese, porções de superfície (22) do corpo (23), que são planejadas para uma conexão com o tecido humano, sendo munidas com uma camada intermediária (24);Petição 870190005249, de 17/01/2019, pág. 5/11b. tornar disponível um metal refratário e também prata e/ou cobre na forma de um ou mais alvos; c. liberar íons do metal refratário e também íons de prata e/ou cobre do um ou mais alvos;d. conduzir os íons, junto com um gás reativo, sobre porções de superfície (22) do corpo (23) cobertas com a camada intermediária (24), de modo que uma camada externa (25) se forma através da qual a camada intermediária (24) fica acessível.
- 7. Método, de acordo com a reivindicação 6, caracterizado pelo fato de que os íons são liberados do um ou mais alvos por meio de um arco elétrico.
- 8. Método, de acordo com a reivindicação 6, caracterizado pelo fato de que os íons são liberados do um ou mais alvos por meio de laser.
- 9. Método, de acordo com a reivindicação 6, caracterizado pelo fato de que os íons são liberados do um ou mais alvos por meio de um feixe eletrônico.
- 10. Método, de acordo com qualquer uma das reivindicações 6 a8, caracterizado pelo fato de que, na etapa a), um corpo (23) fica disponível no qual a camada intermediária (24) consiste de prata, ouro e/ou cobre.
- 11. Método, de acordo com qualquer uma das reivindicações 6 a9, caracterizado pelo fato de que, na etapa c), fragmentos com um diâmetro maior do que 20 pm são adicionalmente liberados do alvo e sendo que, na etapa d), os fragmentos são conduzidos sobre o corpo (23).
- 12. Método, de acordo com qualquer uma das reivindicações 6 a10, caracterizado pelo fato de que, antes da etapa d), a porção da superfície do corpo a ser revestida é coberta com uma máscara feita de um material de temperatura estável.
