From small shoes to large villas, 3D printing is changing public life. This technology has entered the medical field, and the sparks are even more amazing – it can accurately print out the pills and privately-made “human bones” to help doctors break through the medical exclusion zone. “Complete surgery that I couldn’t think of in the past. ".

1:1 scale printing bone surgery for "private ordering"

The 3D printed prosthesis connects the lower limbs and the important hub of the foot, and such surgery has been in the theoretical stage of discussion worldwide. Recently, a hospital in western China successfully applied this medical concept to the clinic.

Mr. Fang, 27 years old, suffered a talus fracture after a fall two years ago, which led to collapse of the talus. On June 29, Mr. Fang was admitted to the Orthopaedic Sports Medicine Center of Southwest Hospital of Chongqing. I heard that the center produced a 3D printed biological function of the personalized talus prosthesis, which allowed him to regain the ability to walk normally. He decided to give it a try.

Director of the Center, Tang Kanglai, introduced that the center had prepared for 72 hours because of the need for 3D printing technology. At 8 am on July 4, the operation officially began. After 90 minutes, a 3D printed prosthesis was successfully connected to the patient's lower limbs and important foot hub, and the operation was successfully completed. At present, Mr. Fang has recovered well and will be able to walk down the ground after 6 weeks to 3 months.

Mr. Fang's 3D talus surgery is just a microcosm of China's use of 3D technology to speed up the realization of surgical "private custom".

At the 4th World 3D Printing Technology Industry Expo held in Shanghai last month, the world's first 3D biovascular printer independently developed by China allowed the audience to witness the charm of technology. It is reported that this technology has carried out clinical experiments on vascular bioprinting on animals. Tang Kang said that in the medical field, there are many applications for 3D printing medical model technology. For example, people can clearly see internal structures, nerves, lymph nodes, etc. through a 3D printed head model.

He said that the application of 3D printing technology is conducive to improve surgical accuracy and surgical success rate, and can optimize the surgical results. In addition, the local lesion model of 3D printing can be used for doctor-patient communication and reduce the difficulty of understanding patients.

The patient was told that the surgery was implanted with a biofunctional talus joint, and he did not understand the technique of 3D printed prosthesis. When Tang Kanglai took the 3D printed talus model, he realized it. "This is exactly the same as my own bones. It's amazing."

According to reports, in terms of support bearing, because the talus is the active joint, Tang Kanglai and his team completely print the talus in 3D according to the ratio of 1:1, and carry out the differential design. The inner material of the talus prosthesis is denser than the outer side, making the prosthesis more For flexibility.

There is no such thing. Earlier this year, the Department of Orthopaedics of Peking University International Hospital successfully completed a 3D printing technique to assist orthopedic surgery. The patient also developed lesions in the talus and involved the ankle joint surface. The lesion was removed + bone grafting. The orthopaedic team of the hospital used 3D printing technology to perform thin-layer CT scan on the patient's lesions, and then reconstructed the talus of the lesion by computer software to make a 1:1 lesion talus model.

Changsha City, Hunan Province, recently implemented surgery for children with “head deformity” in combination with 3D printing technology. This is the first time in the region that 3D printing technology has been used to achieve “private ordering” of surgery.

Tang Kang said that the previous surgical operation relied on the actual anatomy and practiced according to the actual situation. The effect can only be seen after the end of the operation and the suture. Now using 3D printing technology, the surgical site required by the patient is reproduced in a ratio of 1:1 before surgery. The physician imagines the cutting plan in the brain while drawing the surgical cutting line on the three-dimensional, real skull model.

“My team and I will tirelessly focus on the combination of 3D printing technology and orthopedic surgery.” Tang Kang said.
