Vol 5 Chapter 2415: big change

"The other two are skin grafting, the difference is that they are divided into autografting and allografting."
"Autologous skin grafting, in simple terms, is to remove the patient's own intact skin and transplant it to the damaged part of the patient's skin. Where is the skin eligible and can be implanted into the patient's disfigured face? The answer is the patient's skin. Hips, butts."
Ha ha ha ha…
Hearing Wu Hao's words, everyone in the audience burst into laughter. They also did not expect that the face was damaged and needed to be repaired with the skin on the butt. Some of the female audience members under the stage did not have to turn red.
Wu Hao said with a smile: "Don't laugh, everyone, this has also been fully researched and practiced. Because this part of the human body is the most delicate and relatively useless, because it basically does not see light, the skin is relatively delicate and fair. And because it basically does not see much light, even if it is removed, outsiders cannot see it, and it will not be affected.
However, the desirable area of ​​skin on the buttocks is limited, and the skin on the buttocks is different from the skin on the face. It does not have the contour of the facial skin and cannot fit perfectly. Therefore, the skin implanted in this way can only play a role of concealing, and may lose the part of the function.
For example, this blushing feature, I am afraid there is no way to realize it on this piece of skin, and there are also some tiny expressions that cannot be realized.
On the other hand, after all, this has brought a certain amount of harm to the patient, and no one wants their to lose skin and become bumpy from now on.
So at this time, medical experts have researched and developed another skin grafting technique, that is, allografting. This skin grafting technique also has a louder name, face replacement.
That's right, it's the face-changing technique that is talked about in many movies and TV dramas.
The face swap is a simple procedure in which the donor's facial skin is removed and implanted into the damaged patient's face. Although it makes no sense that people's faces look different, these are determined by the internal musculoskeletal tissue, and the facial skin is a piece of skin.
So we can use this skin to repair the damaged facial parts of patients. The skin that is not much different in itself can perfectly fit the damaged face of the patient, and can perfectly connect with the surrounding intact skin.
The biggest advantage of this kind of surgery is that it can be tailored, how much is needed, how much is used, and it can be repaired perfectly, and the effect after repair is very good. In addition to some nerve tissue in the face, some damage may occur due to the problem of surgical precision, resulting in some dysfunction. Others can basically achieve the same curative effect as the original face.
However, this face replacement technique also has some disadvantages or side effects. The first is that it may involve some ethical and moral issues, which is similar to the face-changing plot in film and television, and will bring about a series of social problems.
On the other hand, there is a problem that comes with this technique, that is, allograft rejection. This also means that patients will have to reuse anti-rejection drugs for the rest of their lives, which is a burden and torture for patients.
Furthermore, there are very few such donors at present, so this technique is only suitable for a small number of people and cannot be popularized. "
Speaking of this, Wu Hao paused for a while, then changed his tone and said: "Our skin implantation has no such problems at all. First of all, it is printed from the patient's own somatic cells, so the source is not the same. There will be problems and there will be no rejection.
And we can also customize the printing according to the patient's face shape or even some of the patient's own requirements, so as to print a pair of skin that can completely fit the patient's face shape and is comparable to the original face.
Of course, due to technical reasons, we are currently unable to print the entire face at once. Not because of our technology, but because the skin tissue we print out is alive, and it needs to be kept alive in order to be implanted on the patient's face and survive.
Theoretically speaking, as soon as this skin is printed, it should be implanted on the patient's face as soon as possible. The shorter the time, the better the survival and recovery effect. If it exceeds a certain time limit, the survival effect will be very poor.
But as we all know, 3D printing is very slow, no matter what kind of printer it is, it needs to be printed little by little, which takes a long time.
Therefore, in order to keep the printed facial skin tissue fresh and ensure that it can survive transplantation, we can only reduce the printing area of ​​the skin. In this way, we need to print the skin in batches, and then transplant them in batches, or through Multiple printers print out these skin tissues, which are then spliced ​​and transplanted.
Despite this, the damaged face we repaired with this technology has a very good effect, basically reaching the level of the original patient's face.
After nearly a year of repair treatment, Zou Feifei was finally cured and discharged. Do you want to see what she looks like now? "
think!
Hearing Wu Hao's words, everyone in the audience shouted.
Okay, Wu Hao nodded with a smile, and then said to the crowd: "Let's welcome Zou Feifei with warm applause, and let her tell us about her heroic deeds and treatment experience."
clap clap clap...
In the warm applause, Zou Feifei appeared on the stage, and then walked towards the center of the round platform with confident steps.
At this moment, Feifei Zou lost the slump in the ward. Instead, she was dressed as a successful urban beauty. Her entire face was very delicate and fair, and she couldn't see any damage at all.
Zou Feifei walked to the round platform while waving her hand. As for Wu Hao, he took the opportunity to get off Wu Hao to rest. After such a long speech, my mouth is already dry and my throat is smoking.
"Thank you, Mr. Wu, for giving me such an opportunity to restore my face, and to stand on this stage to share with you my mental journey in this period of time..."
Zou Feifei started from saving people to being rescued, and then went to Anxi to receive treatment and talk a little bit. The big screen is some daily pictures she recorded with the camera. Especially after comparing the disfigured face and the current face, the audience burst into exclamations.
Everyone stared at Zou Feifei's face, and the camera also gave a close-up of her face. But no one could see that this delicate and fair face was once so tattered.
This is simply amazing, like a big change of life. And even more amazing, not only her delicate face, but also her piercing eyes, including the eyebrows and hair that had been completely burned out, all appeared miraculously.
Although the current Zou Feifei still has handsome short hair like a boy, but the hair is very thick and does not look like it has been burned at all.
