Chapter 1931 Face Changing Technique!

After speaking, Qi Feng looked at Wu Hao and several experts, and several experts looked at each other and looked at Wu Hao. Wu Hao did not answer immediately, but stared at the photo and thought.

Seeing that Wu Hao had not spoken for a long time, Wu Jiuzhi relieved the atmosphere and said with a smile: "Actually, there is still a way, and that is allogeneic face transplant surgery. If the face of the donor is replaced with the patient's face, all problems will be solved."

Face changing?

Not only Qi Feng, but also Xu Shenghua and Zhang Qinghong looked at him. Wu Hao also came back to his senses and looked at Wu Jiuzhi, obviously very interested in what he said.

"Actually, it's nothing new. This kind of surgery has been successfully performed in several cases in Europe and the United States." Wu Jiuzhi saw the interested looks from everyone, and then introduced with a smile.

"As early as the beginning of this century, some experts tried to perform face transplant surgery, but were blocked. Then in 2005, Laoguo performed the world's first "face transplant" surgery, successfully treating a man who was bitten by a dog and disfigured.

A woman's face was changed. The patient successfully woke up and regained consciousness one day after the operation. It is said that the patient recovered well after the operation and was able to open her mouth to eat strawberry chocolate, drink coffee, juice, etc.

This was the earliest recorded case of face transplant surgery. Later in 2009, American surgeon Semyonov also performed a face transplant on a human being and achieved success.

Semyonov has been working on face transplant surgery and conducted a lot of research on old books and cadavers. At the end of 2008, she used the muscles, bones, upper lip and nose of an anonymous donor to

A young woman had nearly 83 square inches of skin transplanted. Two months later, the patient, whose name and appearance did not want to be revealed, had regained some basic functions on her face, such as having a sense of smell and being able to drink from a cup.

Semyonov said at a later academic conference that the patient, who had no nose before, could not only eat hamburgers, but also taste and smell them.

In another five years, the University Medical Center of Milton held a press conference and announced that they had completed the most complex face transplant surgery to date. The patient of the surgery was a firefighter who fought in a fire at the beginning of the century.

The face was severely burned, and the eyelids, lips, ears, most of the nose, hair and eyebrows were burned. After more than 100 doctors, nurses and other staff worked hard for more than 20 hours, they finally completed the operation successfully.

.”

After hearing Wu Jiuzhi's introduction, Xu Shenghua couldn't help but touch his chin and said: "This case is worth learning from. Is there any more detailed information that can provide us with some inspiration and reference for treatment?"

Wu Jiuzhi nodded and said: "There should be some, but it has been a long time, and I don't know how many more can be collected. I will ask the students to sort them out and send them to everyone later."

As for Zhang Qinghong, Director Zhang shook his head slightly at this time and said: "I have heard of allogeneic facial transplantation, which is what we call face replacement surgery, but this surgery itself is extremely controversial.

First of all, as doctors, let’s talk about the technical aspects. The entire face must be completely removed from the donor’s head, and then the damaged face of the patient must be removed, and then the donor’s face can be transplanted. The purpose of this operation is

The difficulty of implementation can be imagined.

I'm not pouring cold water on this, but who among us can guarantee the success of this operation?"

As he spoke, Zhang Qinghong glanced at everyone, and then continued: "The face is also one of the more complex parts of the human body's nerves and muscles. There are many nerve tissues and blood vessel networks on it. How to achieve precise docking of these blood vessels, and how to complete the perfect allograft face shape

Fitting, these are all technical problems.

In addition, there is a physical issue. Who will agree to donate their own face or the face of a relative? Even if someone is willing, different people's face shapes are very different. To find a perfect match, family members must agree. This

I'm afraid it will be even more difficult.

Which family member would agree to have their relative's face grown on someone else, and how the patient with the implanted face should be identified, these are all questions.

Finally, there is the rejection reaction. As we all know, patients need to take different medications to resist the rejection reaction caused by the foreign organ. This process is also very painful."

After listening to Zhang Qinghong's words, everyone paused and remained silent for a long time.

Wu Hao, on the other hand, hesitated for a moment, and then said to everyone: "There shouldn't be any big problems with surgical technology. It can be solved by using our multi-tentacle surgical robot."

"Then the next step is this skin, or where the face comes from. Do we really need to find a face to put on the patient?"

Xu Shenghua asked everyone, then looked at Wu Hao and said, "Tell me about your bio-3D printed skin and how far you can achieve it."

Hearing what he said, everyone present looked at him. Wu Hao smiled bitterly upon seeing this, and then said to everyone: "The area of ​​​​the human face is about three hundred to four hundred square centimeters, and what we announced before

The current printing limit of this 3D bioprinter is 123 square centimeters.

Even if we use ten printers to print continuously, we can only obtain more than one hundred square meters of skin, which is still far from the entire face.

Moreover, these skins are relatively fragile, so implanting them on the patient’s face will create a broken face, which will be even more terrifying.”

Hearing Wu Hao's words, Xu Shenghua immediately waved his hand and said: "I don't want to hear your public data, I just want to know what you can actually achieve."

"Twenty or thirty square centimeters, this is our current limit." Wu Hao spread his hands and said helplessly.

That's enough. We need to prepare several more printers to print at the same time, so that we can obtain a very objective area of ​​skin. Moreover, the entire transplantation process does not need to be completed in one go. This is too risky and the operation is too difficult, so I still

It is preferred to use multiple transplants to gradually restore the patient's appearance.

After hearing what Xu Shenghua said, Wu Jiuzhi also said: "As for the scars at the splicing of different skins, this can also be solved. During the implantation process, medical and cosmetic experts will be involved to sew the skin and pre-treat the wounds.

, and then through later adjustments and repairs, these scars can be repaired without causing too obvious scars, or even completely eliminated."

Seeing that Xu Shenghua and Wu Jiuzhi had said so, Qi Feng also said to Wu Hao: "Mr. Wu, since the two experts have said so, I think it is better to just let this matter be settled. Anyway, the patients have already arrived.

Well, we can't let her leave disappointed again.

Many people are paying attention to us now, and if we can’t deliver a satisfactory answer, I’m afraid people won’t buy it easily.”

Speaking of this, Qi Feng patted Wu Hao on the shoulder and comforted him with a smile: "We all know your worries, but there is a first time for everything. Don't worry, we will bear it with you this time."
