Professor Liu Zhongjun, the chief surgeon and head of the 3D printed artificial vertebral research team, said that the artificial vertebral body produced by 3D printing technology is reconstructed and fixed according to the patient's anatomy. With such an artificial spine that is similar in shape to function from the original anatomy of the human body, the patient can live and work like a normal person. It is understood that in the past, the titanium mesh was used to fill the autologous or allogeneic bone as the interbody support device, but once the titanium mesh was displaced and the spinal cord was compressed, the patient would be paralyzed.
It is reported that in 2009, Peking University Third Hospital introduced 3D printing technology into the field of orthopedics. After interdisciplinary and cross-disciplinary cooperation, after years of research and clinical observation, on May 6 this year, the world's first metal 3D printed human implant - artificial vertebral body was born and approved by the State Food and Drug Administration, marking the In the field of 3D printed implants, China has already taken the lead in the world, and Chinese manufacturing will benefit more patients. After the localization of the products, it will also break the monopoly of foreign products on the high-end market, significantly reduce the price, save large medical expenses for patients, and have a milestone significance for promoting the development of the entire 3D printing industry chain.
The registered artificial vertebral body products belong to the three types of orthopedic implants directly implanted into the human body, and are the medical equipment products with the highest supervision level in China. The product was developed by Liu Zhongjun, Cai Hong, and Beijing Aikang Yicheng Medical Equipment Co., Ltd., an orthopaedic surgeon at Peking University Third Hospital. The 3D printed artificial hip joint product developed by the team was approved as the first 3D printed human implant approved by CFDA in China in 2015, which means that the 3D printed implant is recognized.
