Military Technology

Hearing Wu Hao's words, Zou Feifei nodded. After all, for her, only Wu Hao, Xu Shenghua and the others can be trusted now. If even they shook their heads and lost confidence, who could she turn to for help?

After comforting Zou Feifei, Wu Hao took a pair of medical rubber gloves from the doctor on the side and put them on, then slowly turned Zou Feifei's head to a more favorable angle, and then leaned in and looked carefully.

The large muscle groups on the face have been basically repaired. Judging from the current repair effect, it is still very ideal.

Hearing Wu Hao's words, everyone present nodded. They can see the changes in the damaged wounds on Zou Feifei's face. It can be said that today's achievements are indeed due to the 3D bioprinting technology supported by Wu Hao and the others.

"The next step is to repair some small muscle groups, nerve tissue, and subcutaneous capillaries. Although it seems to be some piecemeal work, the amount of work added together is still relatively large, and this is a delicate work, not blindly. Greed fast, have to take it slow.

Of course, in order to reduce the number of operations as much as possible, thereby reducing postoperative pain and a series of other problems for patients, my suggestion is to focus on repair, that is, to perform multiple rounds of repair operations in one operation. "

Hearing Wu Hao's words, Zhang Qinghong was a little worried: "This can indeed reduce the number of operations, but there is a problem that needs to be solved, that is, can we obtain enough repair materials at one time, that is, bio-3D printed tissue. You know, we The progress of the current repair work depends entirely on the efficiency of the 3D bioprinted tissue. Of course, it is good to perform multiple repairs at one time, but the efficiency of the 3D bioprinting cannot meet the demand.”

Zhang Qinghong's words naturally attracted everyone's approval. Indeed, it is not the hospital side that affects the progress of the patient's treatment, but Wu Hao's side. So when Wu Hao said this, Zhang Qinghong asked a question.

Regarding the problem mentioned by Zhang Qinghong, Wu Hao swept the crowd and shook his head with a smile: "This problem is not difficult to solve, first of all, because the following are some small muscle groups, nerve tissue, capillaries and other tissues. For organ transplantation and repair treatment, the biological 3D printing tissue required is relatively small, so the time required for printing is relatively short.

And because the volume is relatively small, the space required for printing is also relatively small, so in this way, we can completely print multiple groups of 3D bioprinted tissues at the same time. In this way, we can obtain a fairly objective 3D bioprinted tissue in one printing.

In this way, we can meet the needs of patients with repair surgery for facial injuries.

Secondly, we will also invest in two new biological 3D printers, both in terms of printing efficiency, printing quality, and precision, which are a great improvement over the previous ones. The two new 3D bioprinters will also be used for 3D bioprinting of some sophisticated tissues and organs. "

Really, that's great. Hearing Wu Hao's words, not only Zou Feifei, Xu Shenghua, Wu Jiuzhi and the others could not help but get excited. The reason why they are so excited is not only because Zou Feifei's treatment and recovery finally has the light of day. On the other hand, of course, I am also excited that the technology of 3D bioprinting is becoming more and more mature. As medical experts participating in the first clinical trial of this technology, they will definitely leave a strong mark in this field.

Even many people present are still figuring out that experts will publish several papers on 3D bioprinting and this case in time.

"If this is the case, then it is entirely possible to focus on using one or two operations to repair the damaged tissue on the patient's face.

After all these are repaired, we will begin to transplant and repair the damaged skin tissue of the patient. Because the damaged area is relatively large, the entire face is expected to undergo three to four operations before it can be completely repaired. "Wu Jiuzhi looked at the wound on Zou Feifei's face and said.

Xu Shenghua nodded and said: "Almost, the difficulty is mainly in the repair of the peripheral facial features, as well as the facial reconstruction surgery."

"Mr. Wu, do you have any ideas or suggestions for the restoration of the patient's damaged facial features?" Zhang Qinghong didn't follow suit, but asked Wu Hao.

Wu Hao didn't speak when he heard the words, but looked down at Zou Feifei's damaged face again, thought for a while, and then said: "First of all, let's talk about the nose, half of the patient's nose has been seriously damaged. It is repaired on the basis of the current damage, which is undoubtedly a rotten beam filled with new tiles, which is not useful.

So if you want to repair it completely, you need to remove the damaged part of the nose, even the good part, and then transplant the new nose printed out by bio-3D, and then transplant it on it, so that it is more intuitive and natural. "

You mean to remove the whole thing and replace it with a new one. This is too risky. Zhang Qinghong frowned upon hearing this.

Xu Shenghua also nodded and looked at Wu Hao and said, "Mr. Wu, the nose is an important respiratory organ. If the entire body is removed and then re-transplanted, is it not necessary? I mean let's be conservative and only damage the upper part of the nose. The parts can be repaired, and there is no need to take so many risks.

After all, the nose is connected to the lungs. If the wound is too large, it is easy to cause lung infection, which will bring life danger. "

Another point, Wu Jiuzhi said: "The overall change will definitely be more beautiful, but I mean to be cautious. After all, the nose is one of the most vulnerable organs on our face, and it is also the organ we often touch. UU Reading www.uukanshu.com

So whether the new nose created by 3D bioprinting can withstand the daily bumping hands, as well as the daily kneading of the patient himself. "

After listening to the words of several people, everyone present nodded.

As for Wu Hao, he did not continue to refute and explain, but looked at Zou Feifei's damaged nose again, and then said to her: "The reason why we talk about this in front of you is to let you have sufficient The right to know and the right to choose. So now the choice is in your hands, do you choose a more aggressive treatment plan or a more stable treatment plan?”

Hearing Wu Hao suddenly asking her, Zou Feifei was a little confused. Facing the crowd, Zou Feifei thought for a while, and then smiled at Wu Hao: "Mr. Wu, what are the advantages of each of these two treatment options, can you tell me? Can you introduce me?"

Hearing Zou Feifei's words, Wu Hao smiled at him and said, "Actually, we have talked too much about this before, so I won't repeat it.

Let me put it simply, choose a more risky and more radical treatment plan, which is to replace the nose as a whole. In this way, the integrity is better, there are no traces of repair and replacement, and you will be given a real nose, and even if you think your nose is too collapsed, you can ask us to print it more straight.

In other words, we can make it more perfect. "
