Imagine that there is a condition in an organ or tissue in your body. You are worried about finding a scarce donor organ. At this time, the hospital used a 3D printer to print a brand new organ transplant into your body, just like replacing it. The old parts on a machine are as simple...
With the development of technology, many scenes that appeared in science fiction movies in the past are no longer a fantasy. For example, the appearance of 3D printers makes it possible for organs to re-create.
In recent years, 3D bio-printing technology has developed rapidly at home and abroad, and surgical models printed using 3D printing technology have begun to be widely used in some hospitals. The use of 3D bioprinters to print in vivo implants that are compatible with the human body, and even the use of cells as "ink" to print out organs has continued to make breakthroughs.
At the end of 2016, Guangzhou Women and Children Medical Center received a patient with “Pierre Robin Syndromeâ€, a rare disease caused by congenital jaw deformity. Children are often difficult to feed, and serious can cause people. Death, so the operation is imminent.
To do this, you need to cut the patient's bone, then stretch it to return it to its normal position, where to cut it (the position of the osteotomy), and the extent to which it needs to be pulled (angle and distance) has precise requirements. It can be said that "the difference is a thousand miles, and it is a thousand miles."
In order to improve the surgical results, doctors used bio-3D printing technology to create a model of the patient's jaw, which effectively improved the efficiency of surgery and the accuracy of surgery.
Studies have shown that there are three main stages in the application of 3D bioprinting: in vitro surgical models, printing of organs and tissues that can be implanted into the human body, and printing of active organs and tissues using cells. The first two phases are currently implemented and are the most widely used phase, and the use of cells to print active organs and tissues is currently the most difficult.
