Abstract

본 발명은 인접하는 척추체 사이에 삽입되어 척추체 유합에 사용되는 케이지 및 그 제조방법에 대한 것으로, 더욱 상세하게는 비다공성의 인서트와; 상기 인서트의 외면을 에워싸는 다공성의 구조체;를 포함하며, 상기 인서트는 상기 케이지의 조작을 위해 사용되는 수술기구와 연결되는 접속부와 상기 접속부의 상면에서 돌출되어 상기 케이지의 길이방향으로 일정 길이 연장되는 연장부를 포함하고, 상기 구조체는 상기 접속부의 상면 및 연장부의 외면에 접하도록 형성되어, 다공성을 가지면서 동시에 강도가 보강된 척추체간 유합술용 다공성 케이지 및 그 제조방법에 대한 것이다.
