  Yesterday, the 2018 China Hospital Innovation Development Summit and the 60th Anniversary of the Founding of Peking University Third Hospital opened in Beijing.The reporter learned that the Peking University Third Hospital has developed all three orthopedic 3D printed human implants in China, and hundreds of patients benefit from it .Experts revealed that there are still vacancies in relevant standards and regulations in this field, and relevant departments are studying and formulating.

  Hundreds of patients benefit from orthopedic 3D printing

  3D printing technology has been widely used in various industries in recent years, and it has its unique strengths in the medical field.The Department of Orthopaedics of Peking University Third Hospital is a national key clinical construction project and the first to eat crabs.3D printing technology was introduced as early as 2009, and it took 3 years to develop China's first 3D printed artificial hip joint product.

  At the seminar, Liu Zhongjun, director of the major surgery department of Peking University Third Hospital, introduced. Internal medicine is an indispensable material in orthopedic treatment, and 3D printing fits well with this demand.Let the internal plants not stop at the level of the regular body, and can also print out personalized and shaped internal plants according to the situation of different patients. Such advantages have made the treatment of the spine tumor, severe trauma and other serious diseases have a breakthrough.Taking spinal tumors as an example, after the patient's spine is “eaten” by the tumor, it needs to be resected, but then the bone filling problem is beyond the reach of traditional treatment methods, and 3D printing can make up for this defect.In addition, the 3D printed inner plant can make a fine microporous structure, allowing the inner plant to fuse with the adjacent structure to achieve bone healing.

  At present, Peking University Third Hospital has developed 3D printing products in all three orthopedic fields in China and applied it to clinical surgery. In the past four years, hundreds of patients benefit from it, many of whom are in critically ill patients.A patient admitted to hospital for spinal tumors was implanted with a 19-centimetre 3D printed matter, and the patient has now returned to normal life. According to reports, some of the hundreds of operations have created the "first case" of the history of spinal surgery in the world, and have not been broken.

  3D printing medical device standard to be released

  Liu Zhongjun also introduced that in addition to solving difficult and serious diseases, the development of 3D printing technology is also conducive to solving the problem of "expensive medical treatment.""Why is the medical treatment so expensive? Medical equipment is a large part. In orthopedic surgery, the cost of equipment should be 2/3. In order to ensure the efficacy, the spinal surgery in the top three hospitals in China basically uses imported equipment.”He said that there is indeed a gap between the quality of domestic products and imported products, but the new technology of 3D printing is standing at the same starting line. Who start firstly will lead it.If the technology is vigorously developed, it will help to seize the high point, and at the same time promote the development of related industries and reduce equipment costs.

  At present, 3D printed medical devices still face problems such as related standard blanks. Liu Zhongjun pointed out that many 3D printing instruments should be customized according to the symptoms of different patients, and China still lacks relevant regulations.He revealed that the relevant departments are currently formulating relevant standards, and will also organize the establishment of expert committees to help participate in the evaluation and approval of subsequent 3D printing equipment.
