Suzhou Hospital keeps pace with 3D printing and reconstructs the spine to "test the knife"
OFweek 3D Printing Network: Yesterday morning, the 12th National Spinal Cord Academic Conference was held by the First Affiliated Hospital of Su Da. This conference is the largest professional conference on spinal surgery in the country. The elites of spine surgery at home and abroad gather in Suzhou to discuss the hottest and focus of the most cutting-edge.
3D printing has been popular for many years and has been used in many fields. At yesterday's conference, the application of 3D printing technology in orthopedic clinics has also become the focus of attention of experts and scholars. Many academic seminars at the conference have made 3D printing the theme.
Professor Liu Zhongjun, the chairman of the conference and the chairman of the Spinal Cord Spinal Committee of the Chinese Rehabilitation Medicine Association, successfully completed the world's first artificially customized axe with 3D printing as a spine surgery plant and stable reconstruction after spinal tumor treatment. Liu Zhongjun said that after the tumor on the spine is removed, the inner part of the plant should be used to fill the missing part. In the past, the metal substitute "titanium cage" was used, but the fixation strength was not ideal. The patient should wear the external fixator after operation. Wearing a steel ring on the head and wearing an "iron vest" on the body, the patient is very painful and there is still no guarantee of safety. “Every person and every vertebra is different. The vertebral body is a special-shaped anatomical structure. There is no way to create the same substitute for traditional techniques. The advantage of 3D printing is that it can make any shape of the inner plant. We can pass CT. The scanned data is converted and printed with a shape and size of the vertebral body. The stability and safety are more guaranteed. The patient does not need to wear the iron shelf to restore more comfortable and safer." Liu Zhongjun said that following the first artificial pivot After the completion of the vertebral body implantation, 3 cases were successfully completed, and good results were obtained. Since China has not yet established regulations for customized medical plants, 3D printing vertebral body implantation is still in the medical exploration stage. In recent years, Liu Zhongjun has rushed to call for speeding up the approval process and applying this product to clinical treatment as soon as possible.
Suzhou is following the cutting edge of the industry and applying 3D printing technology to orthopedics. Yang Huilin, director of the Department of Orthopaedics of the First Affiliated Hospital of Su Da, said that the orthopaedic expert team of the hospital has been conducting orthopedic treatment with 3D printing technology for more than five years. At present, the 3D printed bone model has been successfully used for simulated surgery, which improves the accuracy of the operation. Yang Huilin expressed great expectations for the implantation of 3D printed vertebral bodies into the human body. He believes that this is the development direction of orthopedic spine treatment, and his team is actively participating in the exploration.

Thermoplastic elastomers have a variety of possible structures, the most fundamental of which is the need for at least two polymer phases that disperse from each other, one as fluid (so that the temperature is higher than its Tg-glassed temperature) and the other as a solid (so that the temperature is lower than its Tg or equal to Tg), and there is an interaction between the two phases. That is, at room temperature to show rubber elasticity, high temperature and plasticization of polymer materials, with rubber-like mechanics and use of performance, but also according to thermoplastics for processing and recycling, it builds a bridge between plastic and rubber. Therefore, thermoplastic elastomers can process rubber products as quickly, efficiently and economically as thermoplastics. In terms of processing, it is a plastic; Thermoplastic elastomers have many characteristics that are superior to thermoset rubber. At present, thermoplastic elastomers have no uniform name, used to use the acronym TPR to represent thermoplastic rubber, TPE means thermoplastic elastomers, both of which are used in related materials. For the sake of unity, it is called TPE or thermoplastic elastomers.
