3D printing is undoubtedly a disruptive technology that is expected to not only change industrial production and daily life, but also enter the field of medical surgery. According to the famous market research institute LuxR esearch, with the rapid adoption of 3D printing technology in the medical industry , it is predicted that the market size will reach 1.9 billion US dollars in 2025, equivalent to more than 10 billion yuan. However, quite different from the market application, China has not yet approved the listing of such medical devices. where is the problem? To what extent can 3D printing technology bring health to all kinds of patients? ã€application】 3D printing has "sneaked into" Guangdong Hospital Recently, Zhujiang Hospital of Southern Medical University used 3D printing technology to successfully print a three-dimensional model of liver simulation of patients with huge complex liver cancer, and successfully guided the completion of complex liver tumor resection. This is the successful application of 3D printing technology disclosed in the capital of the top three hospitals in Guangdong Province. But this is not the first application in the hospital industry. Xu Guisheng, an orthopaedic surgeon who graduated from Shantou University Medical College, told the Southern Reporter that the application in this area has already begun quietly in several large hospitals in Shenzhen. "The current application of 3D printing in Shenzhen Grand Hospital is as a clinical teaching model, and the second is as a simulated organ to optimize the surgical path, thereby improving the accuracy of the operation, reducing the operation time and reducing the risk of anesthesia. Shenzhen Second People's Hospital That is, the first successful use of 3D printing technology, the titanium shoulder scapula prosthesis is accurately produced for patients with scapular tumors, and the prosthesis is implanted after the tumor is removed." A more typical success story is the victim of a meat grinder in Guangdong two years ago. A 5-year-old boy recently made a prosthetic limb by 3D printing technology. The pinch function. "The reason why 3D technology is the first to make progress in orthopedics and stomatology is because orthopedics have their own particularity. There are obvious differences between bones and surrounding tissues. CT, nuclear magnetic and other technologies can be used to scan more accurate graphic data and print accordingly. The 3D model has higher accuracy." Zhang Wei, chief physician of the Department of Urology, Peking University International Hospital, said in an interview with Nandu. According to public information, the application of 3D printing technology in the medical field is mostly focused on printing bone models, tooth models, Artificial joints and other aspects. ã€technology】 Difficulties in the internal organs However, there is another side to the coin. In the soft, full-filled internal organs, 3D printing is also faced with many difficulties such as easy distortion of data and difficulty in increasing surgical accuracy and success rate. According to Zhang Wei, in the medical field involving internal organs, the application of 3D printing technology mainly has two levels, anatomical printing and biological printing. The former refers to the use of 3D printing technology to imitate organs in advance during anatomical surgery, to make stereoscopic and accurate models, to help doctors better plan the operation before surgery, and to guide the surgical process during the operation. The latter is the need to use active cell materials to print living organs with biological activity and body compatibility. "It can be said that anatomical printing is mainly to accurately replicate organs, and cell printing is a regenerative organ. The former is the technical basis of the latter, and the latter is the ultimate vision of the former. But compared with the bones, it penetrates the internal organs of the human body and the surrounding blood vessels, Soft tissue and other differences are difficult to identify effectively, and it is easy to cause data distortion," Zhang said.
