Hearing Qi Feng's words, Wu Hao smiled and shook his head: "I'm 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 to treat heroes.
In fact, what I was thinking about was how to treat this patient.
The patient, Lu Feifei, was very beautiful before her disfigurement, and her slightly baby-fat face made her look very cute.
Comparing her current disfigured face, it's almost like clouds and mud. So how to restore her original appearance, there are actually many options, such as using homologous skin grafting technology, and continuing the prosthetic skin from the patient's buttocks or thighs for treatment.
.In this case, rejection can be rarely avoided. Moreover, there are many cases of this type of surgery, and the risks should be minimal. Moreover, the related effects obtained are relatively ideal, and the patient's appearance can also be basically repaired.
This is currently the best method, but patients have limited affordability and are somewhat repelled and worried about this method.
Therefore, you can try the second method, which is the simultaneous transplantation method. First, transplant skin from the patient's buttocks and thighs to repair the patient's face and other exposed skin. Then target the damaged areas where the patient's skin has been transplanted.
The buttocks and thighs are repaired using our bio-3D printed skin tissue. In this way, we can achieve results that are basically satisfactory to the patients, which is also an explanation for the public."
After speaking, Wu Hao glanced at everyone present, and then continued: "The second option is to directly use our bio-3D printed skin tissue for transplantation to repair the damaged appearance.
But as I said before, our current limit is twenty or thirty square centimeters, and we cannot give any more, and then we will repair it bit by bit. 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 tests. Therefore, it is unknown whether it will be successful in clinical trials.
And there is another point that everyone should pay attention to, that is, not only the skin of the patient's face is damaged, but also the nerves and muscle tissue. If this part cannot be repaired, then even if we complete the facial skin implant, it will only be for the patient.
When a mask is implanted, the patient cannot control his smile, including some other facial movements, and may even be damaged when eating. We even found that the patient has several perforations on his face and mouth that he wants to repair.
It's difficult.
I don’t know if you have considered this issue, and do you have any treatment and repair plans?”
Speaking of this, Wu Hao paused, glanced around at everyone, and then continued: "Actually, I have a more bold plan here. I discussed it with our technical experts before and thought that although this plan is a bit too
It's a risk, but if we succeed, we may create a miracle."
What plan? After 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 smiled and said: "This plan is not actually a plan, but our experts are discussing how to restore this patient's best appearance from a technical perspective.
There is no doubt that replacing you as a whole is the best choice. Through face transplant surgery, we can directly clean and remove the patient's damaged face, and then replace it with a complete face, so that the patient can restore his normal appearance.
.
But in this case, the key to 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 as everyone knows, with our current bio-3D printing technology, we can only print 20 to 30 square centimeters of skin at the most extreme, which is not enough to print an entire face.
Even if we print the entire face through multi-step 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 repair, just like laying bricks, building and repairing it bit by bit.
That is to say, the facial muscle and nerve repair is carried out simultaneously with the facial skin tissue repair, and the facial muscle and 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 bio-3D printers to print these muscles and nerve tissues. If successful, patients will no longer have to suffer other pains.
If the printing fails, then we can only extract these muscles and nerves from the patient's thigh. Compared to the thigh, I believe the patient should care more about their face."
What you mean is to directly remove all the damaged parts of the patient's face, and then carry out step-by-step repairs on the new basis to repair the patient's face again.
Wu Hao smiled and nodded: "That's right, it's the example I gave. Before building a house, you must have a good foundation. If the foundation is unstable, then the house that is built better will shake or even shake because of the unstable foundation.
Collapse, quality is worrying.
Instead of building on the broken eaves and broken walls, it would be better to bulldoze and build a new one."
But facial repair surgery is not about building a house. If you do it this way, do you know how difficult the surgery is and how much risk you have to bear? Zhang Qinghong frowned and said with a worried look on his face.
Wu Hao laughed when he heard this: "I'm just saying this from a technical point of view. If you think it's unreasonable, you can completely ignore it and just follow the plan you mentioned.
It is our job and responsibility to make changes, and we will try our best to cooperate. Don’t worry, we will definitely not delay everyone from showing their talents.”
After hearing Wu Hao's words, Xu Shenghua comforted him and said: "Hey, Xiao Wu, what you said, let's all find a solution together, don't be so impulsive.
The plan you proposed is indeed creative and the most effective one, but as Director Zhang is worried, it is also the riskiest one.
So as to how to proceed, I think we still need to consider the opinions of all parties and then choose a solution that is both effective and 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."
