Data show that a total of 18 people a day in the world are dying because they cannot find a suitable organ transplant. But the situation is expected to change, and in the future we may be able to get the right organs through 3D.
"Economic reference newspaper," The interview learned that the United States Organovo Company has been using 3D printing technology to develop human liver tissue for toxicological prediction and disease modelling, and plans to be formally commercial at the end of this year. With the increasingly mature technology, 3D printing will set off the industrial revolution of medical industry.
Application market will exceed billions
A special operation is underway at the orthopaedic office of the Nineth People's Hospital affiliated to Shanghai Jiaotong University School of Medicine.
This is a pelvic tumor patient, after the diagnosis and treatment of most of the pelvis was removed, faced with the risk of disability, the doctor is trying to get him to stand again walking.
Chinese Academy of Engineering, orthopedic director Dai Karki Rong Professor introduced, in accordance with the previous approach, is generally used to make a good "general-purpose" metal products or treated allogeneic bone repair bone huge defect, but poor matching, the effect is not good. Now they are trying to "print" a new pelvic for patients with a 3D print technique.
Before the surgery, they used CT scans and magnetic resonance imaging to collect complete pelvic and tumor data, and on this basis, a stereo image of the patient's pelvis was constructed in the computer, and the boundaries of the tumor and the scope of the surgical resection were given. At the same time, a complete pelvic model of the patient is printed out with a 3D printing device. After the model was simulated by the physician, according to the incomplete condition of the model, the artificial half pelvic prosthesis was manufactured and simulated, installed and modified on the model, and then the real pelvic prosthesis was printed with titanium alloy after the simulated installation. After surgical resection of the tumor, implants are implanted and are accurately connected with the residual pelvis. Customized pelvic surface can also be a special coating or micro-pore structure, conducive to surrounding tissues and false shape into one. The final operation was successful and the patient was able to stand and walk.
It is learned that from the late 80 's, Dai Karki's medical team began to use 3D printing technology, rapid prototyping technology in orthopaedics, has made use of 3D printing technology for nine homes and other hospitals in hundreds of cases of severe limbs and pelvic lesions of patients with different parts and shapes of individual bone joint repair prosthesis, and success.
