[China Pharmaceutical Network Technology News] As long as you have raw materials and drawings, 3D printers can print them out. Now 3D printing has become popular all over the world, but when the trend of 3D printing turns to serious medical aspects, what will happen? What about the spark?
In the 1990s, the world's first 3D printer was introduced at the Massachusetts Institute of Technology, and then 3D printing became popular around the world. Aerospace defense, housing design, heritage protection, manufacturing, fashion design, and even the food industry can all see 3D printing. The figure.
Urbee is the world's first car to be produced using 3D printing technology. Manual assembly, body covering and other materials are made with 3D printers.
The principle of 3D printing technology is similar to that of ordinary printers. The printer is equipped with "printing materials" such as liquid or powder. After connecting with the computer, it is controlled by computer, and the printed materials are superimposed layer by layer by light curing river paper lamination technology. Become a real thing. In other words, as long as you have raw materials and drawings, 3D printers can print them out. Then, when the trend of 3D printing turns to a serious medical aspect, what kind of spark will it collide?
3D printing orthopedics
In 14 years, Wang Jincheng and the team of the Orthopaedic Hospital of the Second Hospital of Jilin University completed the world's 3D printing double elbow artificial joint and wrist joint replacement surgery.
Professor Wang Jincheng description: "The analogy, traditional production prosthesis is subtracted, the doctor uses a model casting prosthesis 'standard', according to the specific circumstances of the patient and which one does not need to cut off, and accurate 3D printing technology of up to 0.1 mm or even smaller, print out the prosthesis can be accurate to the patient native bone the same size, the surgery more personalized, precision of. "
"In addition, the porous structure of natural bone surface can easily be 3D printed" skeleton "copy, they can be like a sponge around the bones come to attract the firm to form one bone between true and false bone, help reduce recovery of patients. "
Since 3D printing is custom tailored for the patient, and can shorten the operation time, reduce the amount of bleeding, and, due to the high degree of simulation, doctors surgery can improve the accuracy and reduce the risk of surgery.
3D printing of surgical assists articles
For some extremely complicated operations, even a senior surgeon will feel pressure. Therefore, if you can prepare in advance before surgery, practicing the surgery on the model will undoubtedly improve the accuracy and success rate of the surgery.
Adanelie Gonzalez, a 4-year-old girl from the United States, has a complete venous ectopic connection (TAPVC) that introduces blood to heart problems due to problems with the veins, causing a series of conditions such as difficulty breathing, lethargy, and weakened immune system.
Due to time constraints and complicated procedures, doctors printed a 3D version of the heart of Gonzalez, and through practice, finally decided to save the Gonzalez before the valuable donation of heart surgery.
3D printing drug articles
In China, there are limited types of drugs for children. In many drug manuals, we can see the description: Children's medication is 1/2 for adults. Therefore, many parents have to take their own pills and measure their own medications. A lot of inconvenience, if you use 3D printing technology, you can give your child precise medication according to the age of the weight.
At the same time, some patients with dysfunction can also use 3D printing technology to print the drug into a porous shape, increase the absorption surface area, and dissolve more easily absorbed by the body.
3D printed organ articles
Since the application of 3D printing technology to medical treatment, the most infinitely desirable is organ printing. Every year, Wang Ping, the head of the China Red Cross Society's Relief and Rescue Department, has listed a very representative set of data: the number of patients who need organ transplants in China is about 1.5 million a year, and only about 10,000 of them can be transplanted. The gap in organ transplantation in China alone is so great, and the world is full of public opinion.
3D printing technology can print out organs only in a semi-successful state. 3D printing can print cells into the same shape as real organs, but its physiological functions are not perfectly replicated. Since most human organs are hollow inside, cells are not attached. It cannot be formed, and the technical problems of blood vessel feeding and formation have not been completely solved. Many 3D printing organs cultured in the laboratory cannot survive for a long time.
In this regard, Zhou Gongyao, vice chairman of China's 3D printing technology industry alliance, is still cautious about printing organs. "The human body system is very complicated. It is a last resort. Organs made of limited technology cannot be used to dock infinitely complex human systems. Life is the first major event. This is also the first difficulty in the development of 3D bio-printing. At present, 3D printing ears, bladder and heart are only in the laboratory. Before implanting the human body, a lot of experiments, accumulation and analysis of a large amount of data are needed, and continuous improvement is required. There are still many things to do."
Zhou Gongyao said, "But some forward-looking research and individual instances of 3D bioprinting are good things that will ultimately lead to the maturity of technology and products."
