Military Technology

Hearing Qi Feng's words, Wu Hao shook his head with a smile: "I am not afraid of taking responsibility, nor am I afraid of worrying about this project. In fact, we are very willing to participate in this project of saving heroes.

In fact, what I was thinking about was how to treat this patient.

The patient Lv Feifei, before the disfigurement, was very beautiful, and her face with a little baby fat made her look very cute.

Compared with the disfigured face now, it is like the difference between clouds and mud. So how to restore her original appearance, in fact, there are many solutions, such as using the technology of allograft skin graft to continue the prosthetic skin from the patient's buttocks or thighs for treatment. In this way, rejection can be rarely avoided. And there are many cases of this type of surgery, and the risk should be minimal. And the related effects obtained are relatively ideal, and the patient's appearance can also be basically repaired.

This is the best way at present, but because the patient's ability to bear is limited, there are some rejections and concerns about this method.

So you can try the second method, which is the simultaneous grafting method. First, the skin is transplanted from the patient's buttocks and thighs to treat the patient's face and other exposed skin. Then, for the damaged buttocks and thighs where the skin has been transplanted, our bio-printed skin tissue is used for repair. In this way, it can also achieve the results that the patients are basically satisfied with, and it can be regarded as an explanation for the public. . "

After finishing speaking, Wu Hao glanced at everyone present, and then continued: "The second plan is to directly use our bio-printed skin tissue to transplant and repair the damaged appearance.

But as I said before, our current limit is twenty or thirty square centimeters, we can't give any more, and then we can fix it little by little. The entire repair time is relatively long, and all repairs are completed, it is estimated that it will take at least half a year.

At present, this technology has not entered clinical trials, and it has only been successful in laboratory and animal trials, so it is unknown whether it will be successful in clinical trials.

And there is another point that everyone should pay attention to, that is, the patient's face is damaged not only by the skin, but also by the nerve and muscle tissue. If this part cannot be repaired, then even if we complete the facial skin implantation, we will only implant a mask on the patient, and the patient cannot control it to smile, including some other facial movements, and may even suffer from eating. damage. We even found that there are several perforations in the patient's face and mouth, which are difficult to repair.

I don't know about this problem, have you considered it, and have any treatment and repair plans? "

Speaking of this, Wu Hao paused, glanced around at the crowd, and then continued: "Actually, I have a bolder plan here. I discussed it with our technical experts before, and I think this plan is a bit too much. It's been a risk, but if we succeed, then we might be able to create a miracle."

What plan? Hearing Wu Hao's words, everyone present became interested, and Zhang Qinghong, who had always been relatively calm, asked.

Wu Hao looked at the crowd and said with a smile: "This plan is actually not exactly a plan, but our experts are discussing how to restore the best appearance of this patient from a technical point of view.

There is no doubt that you are the best choice in exchange for the whole. Through face replacement surgery, we can directly clean up and remove the damaged face of the patient, and then replace it with a complete face, so that the patient can restore the appearance of a normal person. .

But in this way, the crux of the problem lies in this face. In addition to finding a donor, the most suitable and effective solution is to use the patient's own somatic cells to print out a face that belongs to the patient. .

But as we all know, with our current bio-3D printing technology, we can only print 20 to 30 square centimeters of skin at the limit, which is not enough to print the entire face.

Even if we print the entire face through the cooperation of multiple or multiple biological 3D printers, how to transplant this is a problem, we have to ensure that these blood vessels and neural networks on the face must be connected together.

Before that, we also have to ensure the integrity of the musculature under the skin of the patient's face.

Therefore, our experts believe that we can try three-dimensional repair, like building bricks, building and repairing little by little.

That is to say, the repair of facial muscles and nerves is carried out simultaneously with the repair of facial skin tissue, and the repair of facial muscles and nerves is performed first.

As for the nerves used for repair, we can extract them from the patient's body and then transplant them in a little bit.

Of course, we will also actively try to use 3D bioprinters to print these muscles and nerve tissues. If it is successful, then the patient will not have to suffer any more.

If the print fails, then we will have to extract these muscles and nerves from the patient's thigh. I believe patients should care more about their faces than their thighs. "

What you mean is to directly take out all these damaged parts of the patient's face, and then build and repair the patient's face step by step on a new basis to restore the patient's face.

Wu Hao smiled and nodded: "That's right, or the example I gave, before building a house, you must do a good foundation. If the foundation is unstable, then a better-built house will also shake or even sway because of the unstable foundation. Collapse, quality is worrying.

Instead of building on top of broken eaves and broken walls, it is better to flatten and build new ones. "

But facial revision surgery is not about building a house. If you do it like this, do you know how difficult the surgery is and how much risk you have to take? Zhang Qinghong frowned and said worriedly.

Wu Hao laughed when he heard the words: "I only said it from a technical point of view, if everyone thinks it is unreasonable, then it can be completely ignored, just follow the plan you said.

Change is our work and responsibility, we will do our best to cooperate, rest assured, we will never delay everyone's ability to show their talents. "

Hearing Wu Hao's words, Xu Shenghua reassured him and said, "Hey, Xiao Wu, see what you said, let's all find a way together, don't be so selfish.

The plan you mentioned is indeed creative and it is the most effective plan, but as Director Zhang worried, it is also the most risky plan.

So how to proceed, I think we still need to integrate the opinions of all parties, and then choose a plan that is not only effective, but also reliable and safe.

If we want to achieve such a goal, we must all work together, so that we can have the opportunity to create miracles. "
