Nowadays, talking about 3D printing technology is nothing new. From toys and parts to exoskeletons and houses, nothing can’t be 3D printed.3D printing in modern timesmedicineIt also occupies an extremely important position. For example, 3D printed prostheses have brought the gospel to many disabled friends.But if it is said that 3D printing is powerful enough to print a heart, it is still a kind of flesh and blood, do you believe it?
Recently, researchers from Tel Aviv University in Israel announced that they used 3D printing technology to take the patient’s own human tissue and print the world’s first complete artificial heart.
This is the first in the world with cells andBlood vessel3D printed heart, its advent may become a huge breakthrough in the field of heart disease treatment.
The heart printed by the researchers in about 3 hours is about the size of a cherry, the size of a rabbit’s heart, but it has clear blood vessels.
At present, cardiovascular disease is the number one killer of humans, and heart transplantation is almost the only option for severely ill patients. Since there are no suitable organs for a long time, many patients can only wait to usher in the end of their lives.
The researchers collected adipose tissue from the patient and separated the cellular and non-cellular material in it.
The separated cells are then mixed with special printing materials to print out the heart tissue suitable for the patient, so that the printed heart will not produce immune rejection, reducing the possibility of many postoperative complications.
At present, the cells in this heart can contract on their own, but they cannot beat and pump blood like a normal heart, so this is the next step for researchers.
According to the plan, they want to start animal experiments in one year to study the feasibility of using this artificial heart for organ transplantation.
This is another perfect match between artificial intelligence and modern medicine, providing another way of thinking for humans to solve cardiovascular diseases.
