At the Digital Orthopaedic Center of Shenzhen Medical College of Southern Medical University, through scanning techniques such as CT and MRI, the deformed or defective bone joints are scanned layer by layer, and then the acquired data is converted into a stereo by using analysis software on the computer. Model and then connect the 3D printer. By setting the appropriate program, the 3D printer will print out a realistic physical model of the bones.
Nowadays, in Shenzhen, the technology of 3D printing patient organ model has been widely used in the surgical planning of departments such as orthopedics, cardiac surgery and neurosurgery. The 1:1 organ model clearly presents the patient's anatomy to the doctor. To a certain extent, help doctors to improve the success rate of complex surgery and reduce the risk of surgery.
Although industry insiders said that at present, China's medical 3D printing technology is almost in sync with foreign countries, and individual fields may exceed them. However, from the current research and clinical application, China's medical 3D printing is still in the process of printing inanimate organ models and bone plant stages, and 3D bioprinting human tissues and organs still have a long way to go.
On August 14, Guangdong Medical 3D Printing Application Transformation Engineering Technology Research Center settled in Shenzhen Medical University of Southern Medical University and established a clinical base, which means that the clinical application of 3D printing technology is rapidly developing. In Shenzhen, what are the new developments in clinical and R&D in 3D printing? What other shortcomings are there? Recently, the reporter walked into hospitals and enterprises, and discussed the future development of Shenzhen medical 3D printing with industry insiders.

3D printing helps doctors break through medical exclusion zones
Into the "Digital Surgery 3D Printing Center" of Shenzhen Medical University, Southern Medical University, three small but powerful 3D printers are neatly arranged on the table, alongside a number of printed samples of bone physical models. Sang Hongxun, director of the Department of Orthopaedics of Shenzhen Medical University, through the printed physical model, to achieve a clear grasp of the damaged parts, displacement and direction of the bones, to understand the patient's condition, and to plan the surgical plan, thus to 3D printing technology Successfully applied to fractures, orthopedics and deformity correction surgery.
"If the patient's bones and joints are seriously deficient, according to the previous method, there may be no way to operate or to replace all the joints. But now with the help of 3D printing technology, you can achieve the number of defects, how much to transplant, achieve accurate medical treatment , you can also Reduce the risk of accidents during surgery." Sang Hongxun told reporters. With the help of 3D printing technology, the team has completed more than 700 orthopedic operations, one-fifth of which are difficult cases, including high-risk cervical, thoracic diseases and congenital spinal deformities.
Preoperative planning is very important for high-risk surgery. Traditionally, obtaining real data of patients through imaging equipment such as CT and magnetic resonance imaging (MRI) is the basis of doctor's surgical planning, but the medical images obtained are two-dimensional. Nowadays, using analysis software, you can turn 2D data into realistic 3D data. 3D printer can directly print 3D models, which can help doctors to carry out accurate surgical planning, improve the success rate of surgery, and facilitate doctors and patients to perform surgery. The program communicates intuitively. In addition, 3D printing can provide a traceable basis for both doctors and patients even after treatment failure.
In July this year, Sang Hongxun received a 70-year-old Mr. Zhang Lao. Because of the severe pain in the cervical vertebrae, Mr. Zhang Lao couldn't even do things like eating, brushing his teeth, and he couldn't walk the road. He could only use a wheelchair. CT showed that Mr. Zhang had severe stenosis of the spinal canal. Six cervical vertebrae in 7 cervical vertebrae had lesions, and spinal stenosis compressed carotid stenosis, which led to his loss of normal mobility. "Traditional methods can choose the way of anterior or posterior approach, but how to expand the narrowed spinal canal during surgery, how to expand, can only rely on the experience of the surgeon, even assistants, nurses, etc. Knowing how to do this operation, the patient will not be very clear about the doctor's surgical plan and effect." Sang Hongxun said. When doing surgery for Mr. Zhang Lao, he first used the 3D printing technology to play the patient's 1:1 cervical vertebra model. Through the model, he clearly knew the degree of the patient's spinal stenosis, and then worked with the surgical team members to develop a surgical plan. The scope of the expansion of the spinal canal, the location and location of the expansion, and the direction and location of the screw to be implanted are planned. The navigation plate is then used for operation, and the operation is very successful. One week after the operation, Mr. Zhang Lao can stand up.
Sang Hongxun, who has more than 20 years of clinical experience in spinal surgery and pioneered spine robotic surgery and digital orthopedic surgery in China, is very optimistic about the broad application prospects of 3D printing technology in orthopedics and other surgical fields. “3D printing plays an important role in preoperative planning, preoperative teaching, intraoperative navigation and guides, and postoperative evaluation.†Sang Hongxun said that 3D printing and clinical integration make clinical surgery more precise, tailored, and tailored. Customized to solve many clinical problems.
At present, in clinical practice, many hospitals in Shenzhen have applied or are conducting clinical trials including 3D printing of physiological and pathological models, personalized navigation guide 3D printing, and personalized implant printing. Among them, Shenzhen Aike Sailong Technology Co., Ltd. independently developed the personalized navigation guide 3D printing has passed the approval of the three types of clinical medical device access in Guangdong Province, which is the first 3D printing personalized navigation guide plate approved by China for clinical application. Further promoted the clinical application of 3D printing technology.
