红网时刻新闻9月13日讯(通讯员 何吉云)“医生,我母亲突发意识不清,怀疑急性脑梗,需要做核磁共振来明确病情,但是她身上装了心脏起搏器,究竟能不能做这个检查呢?”放射影像科的医生常常遇到类似的问题,比如:体内有心脏、血管支架,心脏起搏器,关节置换等金属物,是否可以做核磁共振?
近日,发表于增材制造顶刊《Additive Manufacturing》的综述文章“Magnesium role in additive manufacturing of biomedical implants – Challenges and opportunities”强调了与镁合金AM相关的问题,讨论了基于PBF的AM工艺用于制造镁基植入物,并与其他AM工艺比较,突出其优势。
中新网黑龙江新闻1月3日电(高军震 周芷含)近日,哈尔滨市第五医院手外科团队运用3D打印钽金属假体植入手术,为一名18岁少年成功修复了长达7公分的胫骨骨缺损,使其行动自如。这项技术的成功应用,标志着3D打印钽金属假体置换术在黑龙江省的应用取得新突破。
Biomedical magnesium alloys have garnered significant attention because of their unique biodegradability, favorable biocompatibility, and suitable mechanical properties. The incorporation of rare earth elements, with their distinct physical and chemical properties, has greatly contributed to enhancing the mechanical performance, degradation behavior, and biological performance of biomedical Mg alloys. Currently, a series of RE-Mg alloys are being designed and investigated for orthopedic implants and cardiovascular stents, achieving substantial and encouraging research progress. In this work, a comprehensive summary of the state-of-the-art in biomedical RE-Mg alloys is provided. The physiological effects and design standards of RE elements in biomedical Mg alloys are discussed. Particularly, the degradation behavior and mechanical properties, including their underlying action are studied in-depth. Furthermore, the preparation techniques and current application status of RE-Mg alloys are reviewed. Finally, we address the ongoing challenges and propose future prospects to guide the development of high-performance biomedical Mg-RE alloys.
