Chinanews Client Beijing, February 10th. On the 8th, the signing ceremony of the "GPS Universal Pelvic Ring Reconstruction System" technology transformation project of the team of Professor Guo Wei from the Department of Orthopedic Oncology, Peking University People's Hospital was held in Beijing.
According to reports, the "3D printed pelvic prosthesis" technology successfully developed by the Chinese scientific research team will not only benefit more patients, but will also break the monopoly of imported products and reduce public medical expenditures.

Clinically, sacrum and pelvic tumors are often very large because they are not easy to find.
For a long time, the pelvis has been regarded as a restricted area for bone tumor surgery.
In particular, combined anterior and posterior resection of sacral tumors was once called "unresectable surgery" in the industry.
Many patients develop paraplegia due to the rapid progress of local tumors. The severe pain makes the patients uncomfortable. For this reason, once discovered, the only treatment is amputation.
In recent years, with the development of 3D printing technology and its continuous expansion in the medical field, the application of this innovative technology in the field of orthopedics has emerged.
In 2015, Guo Wei's team developed a full range of 3D printed pelvic ring artificial prostheses (GPS universal pelvic ring reconstruction system) such as sacral restorations, iliac restorations and acetabular defect reconstruction prostheses. The research results have successively obtained national scientific and technological progress. Second prize, the first prize of China Medical Science and Technology Progress Award, and the second prize of Beijing Science and Technology Progress Award.
According to reports, the "3D printed modular artificial half pelvic prosthesis" (Globle Pelvic System, referred to as GPS) was designed in 2015 to further improve the "artificial half pelvic prosthesis" designed in 2002 for the reconstruction of pelvic tumor limb salvage surgery. "Prosthesis" to further optimize the mechanical design of the semipelvic prosthesis and increase the bone ingrowth function of the prosthesis. Through research, it has been found that the prosthesis can perfectly fuse with the patient's autologous bone.
So far, more than 300 cases have been used clinically, and good clinical results have been achieved, with greatly reduced complications.
GPS consists of four parts, which respectively perform different functions, replacing the removed pelvis, sacrum, hip joints, etc., and helping patients to stand up again and walk normally.
On the 8th, the signing ceremony of the "GPS Universal Pelvic Ring Reconstruction System" technology transformation project was held in Beijing.
"From scientific ideas, to laboratory results, to mature products, the road to industrialization is difficult and long, but it will undoubtedly promote medical progress and benefit more patients." Jiang Baoguo, Dean of Peking University People's Hospital Said.
It is reported that the implementation of this project has achieved the goal of China's independent research and development of artificial prostheses for pelvic tumors, which will break the monopoly of imported products and reduce public medical expenditures. (Finish)
