According to Japanese media reports on March 12, 3D printing technology is currently being used in a large number of surgical operations. Since the fall of 2013, the Joint School of Medicine, Nagoya University School of Medicine in Japan has jointly produced a model of the internal organs that accurately displays the blood vessels and lesions inside the body, and put them into the use of simulated surgery. In early March, three doctors in the operating room of Nagoya University conducted a simulation experiment on a liver model that was only 70% in size. Because the day was a liver tumor resection for a male patient in his 70s, and in order to successfully remove a tumor with a diameter of only a few millimeters, the doctors repeatedly tested the model on the liver against the solid liver to determine the location and operation of the tumor. Method of development. It is understood that because the liver is brown and opaque, its internal blood vessels are complicated in layout, so it is a huge problem to remove small tumors accurately. Since the fall of 2013, Nagoya University's Oncology Surgery has begun to use this model for tumors that are difficult to identify in previous physical examinations and for difficult operations. A doctor in the department said that using the model allows the doctor to correctly grasp the relevant position and help the doctors communicate with each other, which makes the operation safer. According to the professor of the engineering team who made the model, they used the CT image to set up the program and computerized the 3D data of the internal organs. Then the data is input into the 3D printer, and then two kinds of acrylic resins for making the internal organs and the internal blood vessels thereof are respectively placed, and the finished product having a thickness of only 0.02 mm is finally formed by repeated application, and the remaining resin is used to polish the surface of the model. . According to the report, the technology is still in the research stage, and the cost is 50,000 yen (about 2,900 yuan). The professor said that he hopes to put the model into insurance application as soon as possible, and will use engineering technology to provide more considerate services for doctors and patients in the future. It is reported that since 2000, the three-dimensional model printed by 3D printer has been officially used in the operation of the surgery, and the bone model used for plastic surgery was also put into insurance application in 2008.
