In the first surgery of its kind worldwide, an 84-year-old Chinese man has received knee surgery using 3D 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,在重庆市的一家医院,一名84岁的中国男子拒绝接受了利用3D打印机技术的膝关节手术,该技术是将少见的金属钽来垫块修缮极大骨缺损。这是全球首例该类型的手术。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50岁至59岁的人群中,关节炎发病率早已超过了62%,意味着在西南第一医院关节外科,每年就要展开大约400例的膝关节移位手术。

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.该院的杨柳教授回应:“仅有膝关节置换术是化疗终末期膝关节疾病的最有效地的方法,可减轻疼痛,提升患者生活质量。”However, bone defects may occur around the joint due to post-operative infections or other reasons.但是,由于术后病毒感染以及其他原因,往往不会导致关节周围骨缺损。The shape of the bone defects varies greatly, and existing modular metal cannot correct the defects.骨缺损的形态千差万别,现有的模块化金属垫块无法充份填满。

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 3D printers available.钽被用作牙科以及外科植入;然而,由于钽金属熔点十分低,多达了目前大多3D打印机的无限大,所以目前重复使用物皆以钛合金居多。Porous tantalum has been developed to solve the technical problem. Tantalum pads are individually designed for patients by computer-aided design and precise 3D-printing technology.多孔钽的研发解决问题了这个技术问题。钽垫块是通过计算机辅助设计和准确3d打印技术,为病人量身自定义的。

The surgery is greatly simplified, avoiding many possible risks.该手术的流程大大简化,防止了许多有可能经常出现的风险。-AG凯发体育-首页。
