3D printing of teeth and bone repair technology has been relatively mature, but the technical maturity of 3D printing cells, soft tissues, organs, etc. may take 5-10 years. —— Luo Jun· Secretary General of the World 3D Printing Technology Industry Alliance
3D printing has quietly entered our lives. Photographs, cars, and aerospace parts can be printed out on the machine as long as the conditions are sufficient. In the medical field, 3D printing technology can make the operation more precise, and bring more hope for recovery.
Make surgery more precise
The Cardiovascular Surgery of Zhengzhou People's Hospital successfully used 3D printing technology, and successfully performed surgery for a child with complicated congenital heart disease of 1 year and 4 months ago. This is the first complex surgery performed in the hospital using 3D printing technology.
"The child is suffering from severe tetralogy of Fallot, and the left pulmonary artery is abnormally small, and the left ventricle is much smaller than normal. No matter which surgical method is adopted, the risk is very high." June 22, Zhengzhou People's Hospital Yang Zaizhen, director of cardiac surgery, told reporters.
Based on the CT data, they entered the patient's cardiac data into a computer and then printed the model in a 1:1 ratio, including bilateral lung arteries and all branches were fully simulated. “In the past, cardiac surgery usually had a certain degree of blindness. Many patients were unclear. Only when the chest was opened, the lesions could be accurately judged. Now we can analyze all the complicated situations before surgery, not only shortening the operation time, but also accurately. Sexuality has also been greatly improved." Yang Zaizhen introduced that in cardiac surgery, because the heart artery is blocked, the instrument is used to maintain blood supply, so the longer the opening time, the longer the blocking time, and the postoperative complications. The higher the probability. The application of 3D printing technology undoubtedly provides patients with more possibilities to restore health.
Not only is cardiac surgery, 3D printing technology is playing a role in all areas of medicine.
Freeze-dried powder is a sterile powder injection obtained by freezing the liquid medicine into a solid state in a sterile environment, and subliming and drying the water in a vacuum. Freeze-dried powder is composed of a bottle of high-purity and high-active biological protein freeze-dried powder and a high-purity liquid essence. When using, it needs to be connected with a patented vacuum to reconstitute the freeze-dried powder and the essence to activate the biological protein activity.
