3D printing "skeleton" knee surgery and other operations can also be customized By relying on the "advance intervention" of 3D printing technology, the skeleton model is printed, and the orthopedic surgery can be "privately customized". Recently, from the Department of Orthopaedics of the First People's Hospital of Qujing City, the department introduced a pre-operative 3D printer, which was the first to apply 3D printing technology to orthopedic surgery such as knee joints and hip joints. Using 3D printing technology, the hospital has successfully performed surgery on five patients. It is understood that the hospital has become the first hospital in Yunnan Province and even the southwest region to introduce 3D printing technology in orthopedic surgery. 1:1 print out the skeleton model "In the past, when a patient had a trauma such as a fracture, the doctor could only perform surgical typing according to the patient's X-ray film, but the X-ray film was mainly due to its planarization, so it is often necessary for the doctor to have a three-dimensional imagination. In order to pave the way for the next operation," said Zhang Yong, director of the Department of Bone, Second People's Hospital of Qujing City. With 3D printing technology, the hospital can advance the CT scan data of the patient to the computer in advance, and print a model 1:1 through the advanced 3D printer to truly realize personal customization. Surgery "personalized", more accurate and forward-looking. Doctors can use this model to achieve simulated surgery. In which part of the operation should be installed steel plate, the curvature of the steel plate, all the problems encountered during the operation can be drilled in advance, and finally completed accurately and quickly during the operation, greatly reduced Steps to reduce trauma and take less than half the time. a few hours to play the skeleton model The 3D printer is nearly 2 meters long and has a liquid crystal display and many buttons next to it, like a large oven with a small door that can be opened. Before the operation, the doctor reconstructed the CT scan data through software to form a three-dimensional image, and injected the printed material into the machine, melting, forming, solidifying and cooling at a high temperature. After a few hours, the hospital will get the printed product. With the bone model of the patient printed in advance, the doctor can perform advanced exercises on the complex relationship of human tissues, blood vessels and nerves that should be avoided during the operation to ensure more stable and accurate operation. On the other hand, this also greatly reduces the incidence of complications such as intraoperative discomfort and postoperative infection. Future or printable human organs What is the magic of 3D printing technology? According to reports, compared with the traditional technology, its biggest advantage is that the bones of what shape you want to do can be. In other words, patients can rely on this technology to achieve "private customization", which is more suitable for the patient himself. The currently applied 3D printing technology is still in its infancy, but it can help patients design surgery in advance and reduce the difficulty of surgery. Zhang Yong said that 3D printing technology is expected to implement the operation of bone internal filling and other operations in the future. For example, if a part of the patient's bone is broken, then a "bone" can be printed. In the future, with the support of biotechnology, 3D printers can print human organs and print out the personalized “components†of the human body. One-stop solution, one machine multi-test
