In the first surgery of its kind worldwide, an 84-year-old Chinese man has received knee surgery using 三维 printing technology to fill large bone defects with tantalum, a rare metal, at a hospital in Chongqing Municipality, reported cqnews.net.据重庆新闻网报导,在重庆的一家医院门诊,一名84岁的我国小伙拒不接受了运用三维打印机技术的膝关节手术,该技术是将罕见的金属材料钽来垫块整修巨大骨缺损。它是全世界第一例该种类的手术。As the incidence of arthritis among people aged from 50 to 59 has reached 62 percent, the first hospital affiliated to AMU (southwest hospital) now performs about 400 knee replacement surgeries annually, according to reports.据报导,在五十岁至59岁的群体中,风湿病患病率早就超出了62%,代表着在西北第一医院骨节普外,每一年就需要进行大概400例的膝关节挪动手术。

Total knee replacement is the most effective way to treat late-stage knee diseases, as it can reduce the pain for patients and improve their quality of life, said Yang Liu, a professor at the hospital.贵院的垂柳专家教授答复:“仅有膝关节融合术是放化疗终未期膝关节病症的最有效地的方式,可缓解痛疼,提高病人生活品质。”However, bone defects may occur around the joint due to post-operative infections or other reasons.可是,因为手术后病毒性感染及其别的缘故,通常不容易造成 骨节周边骨缺损。

The shape of the bone defects varies greatly, and existing modular metal cannot correct the defects.骨缺损的形状各有不同,目前的模块化设计金属材料垫块没法充份铺满。Tantalum is used in dental and surgical implants; however, titanium alloy is more commonly used as the high melting point of tantalum exceeds the limit of most 三维 printers available.钽被作为口腔科及其普外嵌入;殊不知,因为钽金属熔点十分低,高达了现阶段大多数三维打印机的无穷大,因此 现阶段多次重复使用物皆以钛金属占多数。

Porous tantalum has been developed to solve the technical problem. Tantalum pads are individually designed for patients by computer-aided design and precise 三维-printing technology.多孔结构钽的产品研发解决困难了这一技术难题。钽垫块是根据辅助设计设计方案和精确3d复印技术,为患者量身定做自定的。The surgery is greatly simplified, avoiding many possible risks.该手术的步骤大大简化,避免了很多有可能经常会出现的风险性。
