Abstract

The invention discloses an osteogenesis promoting rubidium-titanium-tantalum-containing composite material, a preparation method thereof and an application of the composite material. According to themethod, sand blasting, acid treatment and alkali heat treatment of a titanium tantalum composite material synthesized by plasma activated sintering are implemented, so that the surface of the titaniumtantalum composite material is modified, rubidium salt penetrates the titanium tantalum composite material with the modified surface through ion exchange, and the material is calcined at high temperature to prepare the osteogenesis promoting rubidium-titanium-tantalum-containing composite material. The composite material has good biocompatibility, does not have cytotoxicity, facilitates cell proliferation and effectively induces pre-osteoblasts to achieve osteoblast differentiation. The material can effectively solve the problems of poor compatibility of bone repairing materials and a human body when the bone repairing materials are clinically applied and the like, and the material has a wide application prospect in clinical bone repairing.

Description

technical field [0001] The invention belongs to the field of biomedical materials, and in particular relates to a composite material containing rubidium, titanium and tantalum for bone formation and its preparation method and application. Background technique [0002] Knee osteoarthritis, hip fractures, and spinal degenerative diseases are all orthopedic diseases with a high incidence rate, and with the aging of the population, the incidence rate of the disease is increasing and younger. Titanium-tantalum composite materials are widely used in the field of clinical orthopedics because of their good mechanical properties, excellent biocompatibility and low cost. For example, joint replacement, spinal internal fixation and other common fracture treatment methods require the use of titanium-tantalum composite materials. material as a bone replacement material. However, since the titanium-tantalum composite material is a biologically inert material, the combination with the hum...
