China-Singapore Online, May 8 (Chen Jing, Xu Ying) Malignant tumors have become a serious problem that threatens human health and life, and the treatment of tumors in the pelvis, hips, knees, shoulders, ankles, wrists and other bones and joints is even more important. It is recognized as a worldwide problem.

  Shanghai Jiaotong University School of Medicine Ninth People's Hospital disclosed on the 8th that during the prevention and control of the new coronary pneumonia epidemic, professor Hao Yongqiang of the hospital's orthopaedic expert successfully removed a huge right pelvic tumor on the right side of a 53-year-old man from Taizhou, Zhejiang, and used 3D Printing technology "tailor-made" personalized surgical plan, implant prosthesis for patients. Currently, the patient is recovering well.

  It is reported that led by Academician Dai Kerong of the Chinese Academy of Engineering and led by the Shanghai Orthopedics Department of the Ninth Hospital, medical and industrial cooperation, the first in the world to introduce 3D printing technology into the development of personalized reconstruction prostheses, created 3D printed personalized lesion models, reconstructed prostheses, etc. Treatment mode. This means that there are new treatments for serious orthopedic diseases such as bone tumors that could not be treated in the past. Hao Yongqiang said that the personalized medical model based on 3D printing technology is a life-saving "send charcoal" for some diseases.

  It is reported that this patient was found to have a pelvic tumor in mid-March. During the period of prevention and control of the new coronary pneumonia epidemic, the patient's tumors are increasing, pain is unbearable, and symptoms such as constipation and swelling of the right lower limb gradually appear. Professor Hao Yongqiang's team prepared a 3D printed pelvic tumor model, 3D printed personalized surgical assistant guide, and 3D printed personalized pelvic reconstruction prosthesis in a short time.

  How to solve the worldwide problem of complex revision after artificial joint failure? In the interview, Professor Hao Yongqiang introduced: "The hip joint is the largest and most important weight-bearing joint of the human body, and it is an important anatomical part connecting the trunk and lower limbs. Whether its function is normal or not is vital to people's walking movement and quality of life." At the time of revision, how to reconstruct the anatomy, mechanics and motor function of the hip joint is an internationally recognized difficulty in reoperation (revision) after the artificial joint fails.

  It is understood that in the 1980s, Professor Dai Kerong cooperated with Professor Wang Chengtao of the School of Mechanical and Power Engineering, Shanghai Jiaotong University to apply 3D printing technology to assist in the design of custom-made revision prostheses, making China become the world in the field of personalized custom artificial joints. Leading level. In recent years, Academician Dai Kerong and Professor Hao Yongqiang took the lead in introducing metal 3D printing into the medical field, which has been used to reconstruct severe trauma, tumors, congenital malformations, revision of prostheses, and complex bone and joint defects. The field ranks in the world's leading level. (Finish)
