The present invention provides a medical implant, which comprises an inner layer body and at least one layer of outer layer body to compose a structure with required shape for implanting. The inner layer body is made of any non-medical grade material (such as non-medical grade materials of metals, polymers, ceramics, and inorganic substances), and the at least one layer of outer layer body is made of any indecomposable medical material (such as indecomposable medical grade materials of metals, polymers, ceramics and inorganic substances), so as to ensure the outer layer body completely encloses the inner layer body. The thicknesses of the inner layer body and the outer layer body may be set according to the requirements for supporting. Thus, the non-medical grade material that has a better structural strength and a lower price may replace a portion of the high-priced medical grade material, whereby the cost for medical implant can be reduced and a reinforced structural support can be formed, which may achieve the multiple improvements of both economical benefits and better durability.本發明係為一種醫療用植入物,係包含一內層體與至少一層的外層體組成植入需求形狀的結構體,該內層體為任何非醫療級材料製成(如金屬、高分子材料、陶瓷、無機物等非醫療級材料),至少一層的外層體為任何不可分解醫療級材料製成(如金屬、高分子材料、陶瓷、無機物等不可分解醫療級材料),以確保外層體完整的保覆內層體,該內層體與外層體可依支撐需求設定厚度;俾以較佳結構強度而低價的非醫療級材料取代部份高價醫療級材料,除可降低醫療用植入物之成本又可形成結構之補強支撐,兼經濟效益及具較佳耐久使用之多重進步性達成者。10...醫療用植入物11...內層體12...外層體
