In the past, before lung surgery, doctors usually only rely on CT data to understand the specific situation of the patient's body, so as to make the operation plan. Nowadays, with the help of 3D printing technology, more and more laboratories around the world have begun to study biological 3D printing technology.
A few years ago, scientists in the Czech Republic used technologies such as 3D printing to create a fully functional lung. They used sophisticated mechanical components and 3D printing models to create a fully functional lung. With this lung model, they can develop many new treatments for respiratory diseases.
Last year, scientists in the United States printed a complex tube of tissue similar to a human lung using food dyes. The team used hydrogels (a polymer gel) to print air sacs that mimic the lungs of human lungs and transmit oxygen to cells in nearby blood vessels. The false lung can beat normally without rupture. The team's research was published in science and on the cover. This study shows that smaller complex structures in the body, such as the intravascular valves of the heart and legs, can also be printed out.
It is understood that more and more 3D printing models are used in medical training and exploration. When it comes to preoperative preparation and analysis, medical students and surgeons can also have more time for detailed preparation. They can see the disease more clearly in the 3D printing model and make the best treatment plan.
