Abrégé
(EN) The invention provides a personalized 3D printing porous titanium-based tantalum metal-coating bone fracture plate with osteoinductive activity. The plate is prepared by taking titanium metal powder or titanium alloy metal powder as a base material, and forming a tantalum coating on the surface of a porous titanium-based bone fracture plate which is prepared by 3D printing processing and has a void structure. The porous titanium-based tantalum metal-coating bone fracture plate has the porosity of 50-80%, the bending strength of 50-150 MPa, the elastic modulus of 2-30 GPa, the void diameter of200-800 [mu]m and the tantalum coating thickness of 30-60 [mu]m, and has sufficient strength and good osteoinductive performance. The implanted bone fracture plate conforming to the anatomical structure of the fracture part can form excellent bone integration with bone tissues, and the problem that a conventional bone fracture plate easily gets loosened and breaks after being implanted into a bodyfor a long time is avoided, so that permanent biological internal fixation is achieved.
(ZH) 本发明提供一种具有骨诱导活性的个性化3D打印多孔钛基钽金属涂层接骨板,其以钛金属粉末或钛合金金属粉末为基材,通过3D打印加工制作的具有空隙结构的多孔钛基接骨板的表面形成钽涂层而制备得到,所述多孔钛基钽金属涂层接骨板的孔隙率为50%~80%,抗弯强度为50MPa~150MPa,弹性模量为2GPa~30GPa,所述空隙的直径为200μm~800μm,所述钽涂层的厚度为30~60μm,具备足够的强度,同时具有良好的骨诱导性能。本发明的接骨板与骨折处解剖结构相符合地植入接骨板,可与骨组织形成优良的骨整合,避免了现有接骨板长期植入体内后存在容易松动和断裂,从而达到永久性生物内固定。
