Hearing Qi Feng's words, Wu Hao smiled and shook his head: "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, Lu Feifei, was very beautiful before she was disfigured, and her face with a little baby fat made her look very cute.

Compared with the disfigured face now, it's like a cloud and mud. So how to restore her to her original appearance, in fact, there are many options, such as the use of homologous skin grafting technology to continue the prosthetic skin from the patient's buttocks or thighs for treatment. In this way, rejection can be avoided very little. Moreover, there are many cases of this type of operation, and the risk should be minimal. And the relevant effects obtained are relatively ideal, and the patient's appearance can also be basically restored.

This is the best way at present, but the patient's ability to bear it is limited, and there is some rejection and concern about this method.

So you can try the second method, that is, the simultaneous transplantation method. First, the skin is transplanted from the patient's buttocks and thighs to treat and repair the patient's face and other exposed skin. Then, for the damaged buttocks and thighs of patients whose skin has been transplanted, we use our bio-3D printed skin tissue to repair. In this way, the results that basically satisfy the patients can be achieved, which is also an explanation for the public. . "

After speaking, Wu Hao glanced at everyone present, and then continued: "The second solution is to directly use our 3D bio-printed skin tissue for transplantation to repair the damaged appearance.

But as I said before, our current limit is 20 to 30 square centimeters, we can’t give more, and then we can repair it little by little. The entire repair time is relatively long, and it is estimated that it will take at least half a year to complete all repairs.

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

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

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

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

what plan? Hearing Wu Hao's words, everyone present became interested, and Zhang Qinghong, who has always been relatively calm, opened his mouth to ask.

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

There is no doubt that the overall exchange for you is the best choice. Through face transplant surgery, we can directly 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 up.

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

But everyone knows that with our current bio-3D printing technology, we can only print twenty to thirty centimeters of skin at its limit, which is not enough to print an entire face.

Even if we print out the whole face by batches or multiple biological 3D printers working together, how to transplant it is a problem. We have to ensure that the blood vessels and neural networks on the face must be connected together.

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

Therefore, our experts believe that we can try three-dimensional restoration, like laying bricks, and build and repair little by little.

That is to say, facial muscle nerve repair is carried out simultaneously with facial skin tissue repair, and facial muscle nerve repair is carried out first.

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

Of course, we will also actively try to use biological 3D printers to print these muscle and nerve tissues. If successful, patients will no longer have to suffer.

If the printing fails, then we can only extract these muscles and nerves from the patient's thigh. Compared with thighs, I believe patients should care more about their faces. "

What you mean is to directly remove all the damaged parts of the patient's face, and then build and repair them step by step on a new basis, so as to restore the patient's face again.

Wu Hao nodded with a smile: "That's right, it's the example I gave. Before building a house, you must have a good foundation. If the foundation is not stable, then the house that is built better will also shake or even shake because of the unstable foundation. Collapsed, poor quality.

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

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

Wu Hao laughed when he heard the words: "I'm only talking about it from a technical point of view~lightnovelpub.net~ If you think it's unreasonable, then you can completely ignore it and follow the plan you said.

Change is our job and responsibility, we will try our best to cooperate, don't worry, it will never delay everyone's ability to show their talents. "

Hearing Wu Hao's words, Xu Shenghua repeatedly comforted him and said, "Hey, Xiao Wu, look at what you said, let's find a way together, don't be so impulsive.

The plan you mentioned is indeed creative and the one with the best effect, but just as Director Zhang is worried, it is also the one with the greatest risk.

So how to proceed, I think we still need to comprehensively consider 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 have the opportunity to create miracles. "
