Precision medicine, 3D printing into medical clinic

Release date: 2015-08-24

"After applying the technology of 3D printing, the preoperative doctor can simulate and then operate. For heart surgery, at least half of the time can be saved in the future. For children, the original heart surgery can not be too long, so that The success rate of surgery can be greatly increased." Liu Jin, the chief physician of the Department of Cardiothoracic Surgery, Shanghai Children's Medical Center, said in an interview with the reporter of China Business News.

Part of the "precision medicine", the medical application of 3D printing is no longer limited to simple bones and limb printing, complex heart and blood vessel printing gradually land, medical applications of 3D printing are gradually coming into reality from dreams, by medicine Beauty has entered clinical applications.

Recently, Shanghai Children's Medical Center announced that it will jointly establish the first “Pediatric 3D Digital Medical Research Center” with the world's 3D printing software service provider, Materialise, Belgium, to combine 3D digital medical research with 3D printing technology for pathological models. Production, play a role in clinical medical teaching and display, pathological mapping and the establishment of sample libraries.

Before surgery, the cardiothoracic surgeon can use the model to explain the surgical plan and risk to the patient, and the heart model in the hands of the doctor is exactly the same as the heart of the patient. Through this three-dimensional heart model, doctors can not only fully grasp the physiological anatomy, but also measure the blood flow of blood vessels at different locations, and perform sufficient surgical simulation before surgery to develop the most comprehensive surgical plan for patients.

"This will greatly improve the success rate of children with complicated congenital heart disease." Liu Jin told reporters that the current application of medical 3D printing is still in the "losing money" stage for hospitals. "Because there is no approval for clinical application, now we are Apply applications and fees to relevant departments to provide 3D printing services to patients in need."

In fact, Kim Francois, general manager of Materialise China, which has been exploring the Chinese market since 2005, told reporters that medical 3D printing service providers who are committed to the Chinese market like them are not rare. “Medical 3D printing involves living bodies and The combination of inanimate objects, hardness, flexibility, and added materials are more difficult than other industrial 3D printing. There are domestic and foreign suppliers to do this, but the first one to be announced recently has obtained CFDA ( China Food and Drug Administration) certified medical 3D printed device approvals from abroad."

In the domestic market, at present, domestic 3D printing dental and bone repair technologies have matured and are rapidly spreading in major orthopedic hospitals and stomatological hospitals; while 3D printing cells, soft tissues, organs and other technologies have been in the process of continuing research and development.

It is reported that 3D printing has two types of applications in the medical field, one is external medical equipment, including rehabilitation aids, prosthetics, medical models, medical equipment, etc.; second, partial treatment of medical implants, such as 3D printed bones, cartilage, joints, teeth and other products are surgically implanted into the body, but the latter is less applied.

In the domestic capital market, medical 3D printing has been inserted into the "precision medicine" and "China wisdom" wings, Deloitte data shows that the medical industry in the segmentation sector accounts for about 15% of the market share of the 3D printing market. Columns are the top three in the industry.

Previously, Guangyunda (300227.SZ) announced at the beginning of this year that it had established Shanghai Guangyunda Medical Digital Co., Ltd. in cooperation with Shanghai Jiaotong University, and officially cut into the field of medical 3D printing.

"At present, our short-term profitability is mainly through cooperation with hospitals to provide medical research, and entering the clinic is the next step, and large-scale profit may still have to wait for clinical release." Kim Francois told reporters.
