After hearing Wu Hao's words, Zou Feifei nodded. After all, the only ones she could trust now were Wu Hao, Xu Shenghua and the others. If even they shook their heads and lost confidence, then 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 an angle that was more conducive to attention, and then looked closer and looked at it carefully.
The repair of the large muscle groups on the face has been basically completed. Judging from the current repair effect, it is still very ideal.
After hearing Wu Hao's words, everyone present nodded. They saw the changes in the damaged wounds on Zou Feifei's face. It can be said that today's achievements are indeed due to the biological 3D printing provided by Wu Hao and others.
technology.
"The next step is to repair some small muscle groups, nerve tissue, and subcutaneous capillaries. Although it seems to be some piecemeal work, the total amount of work is still relatively large, and this is a delicate job that cannot be done blindly.
If you are greedy for speed, you must take your time.
Of course, in order to reduce the number of surgeries as much as possible, thereby reducing the patient's postoperative pain and a series of other problems, my suggestion is to focus on repairs, that is to say, perform multiple rounds of repair surgeries in one operation."
Hearing Wu Hao's words, Zhang Qinghong said with some concern: "This can indeed reduce the number of surgeries, 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 current progress of repair work completely depends on the efficiency of bio-3D printing tissue. It is good to perform multiple repairs at one time, but the efficiency of bio-3D printing cannot meet the demand."
Zhang Qinghong's words naturally attracted everyone's approval. Indeed, it is not the hospital that affects the progress of patient treatment, but Wu Hao and the others. That's why Zhang Qinghong asked questions after hearing what Wu Hao said.
Regarding the problem mentioned by Zhang Qinghong, Wu Hao glanced at the crowd and shook his head with a smile: "This problem is actually not difficult to solve, first of all, because the next ones are small muscle groups, nerve tissues, capillaries and other tissues.
For organ transplantation and repair treatment, the bio-3D printed tissues required are relatively small, so the time required for printing is relatively short.
And because the volume is relatively small, printing requires less space. In this way, we can print multiple sets of biological 3D printing tissues at the same time. In this way, we can obtain quite objective biological 3D printing tissues in one printing.
In this way, we can meet the needs of patients related to facial damage repair surgery.
Secondly, we will also invest in two new biological 3D printers, which will be greatly improved in terms of printing efficiency, printing quality and accuracy compared to the previous ones. These two new biological 3D printers will also be used for some precision
Bio-3D printing of tissues and organs.”
Really, that's great. After hearing Wu Hao's words, not only Zou Feifei, but also Xu Shenghua, Wu Jiuzhi and others couldn't help but become excited. The reason why they were so excited was not only because Zou Feifei's treatment and recovery finally had hope.
On the other hand, of course, I am also excited that the technology of bio-3D printing is becoming more and more mature. As medical experts who participated in the first clinical trial of this technology, they will definitely leave a mark in this field.
Many people present were even thinking about how many papers experts would publish on 3D biological printing and this case.
"If this is the case, then one or two surgeries can be used to repair the damaged tissue on the patient's face.
After these are repaired, we will start transplanting and repairing the patient's damaged skin tissue. Because the damaged area is relatively large, it is expected that the entire face will require three to four surgeries before it can be completely repaired."
Wu Jiuzhi looked at the wounds on Zou Feifei's face and said.
Xu Shenghua nodded and said: "It's almost the same. The main difficulty lies in the repair around the facial features and the surgery to reshape the facial features."
"Mr. Wu, do you have any ideas or suggestions regarding the repair of the patient's damaged facial features?" Zhang Qinghong did not follow, but looked at Wu Hao and asked.
Wu Hao did not speak when he heard this, but lowered his head again to look at Zou Feifei's damaged face, 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. If only one
It is to be repaired on the basis of the current damage. This is undoubtedly a rotten beam filled with new tiles, which is of no use.
Therefore, if you want to completely repair it, you need to remove the damaged parts of the nose, or even the good parts, and then transplant the new nose from the 3D bioprinting onto it, which will be more intuitive and natural."
Do you mean to remove the whole body and replace it with a new one? This is too risky. Zhang Qinghong frowned when he heard this.
Xu Shenghua also nodded and looked at Wu Hao and said: "Mr. Wu, the nose is an important respiratory organ. If it is completely removed and then re-transplanted, it is not necessary. What I mean is that we should be more conservative and only damage the upper part of the nose.
Just repair the parts, there is no need to take so many risks.
After all, the nose is connected to the lungs, so if the wound is too large, it can easily cause lung infection, which can be life-threatening."
Another point, Wu Jiuzhi said: "It will definitely look more beautiful if it is replaced as a whole, but I also mean it with caution. After all, the nose is one of the most fragile organs on our face, and it is also an organ that we often touch.
So whether the new nose that is bio-3D printed can withstand daily collisions on the hands, as well as daily kneading by the patient himself."
After listening to what a few people said, everyone present nodded.
As for Wu Hao, he did not continue to refute or explain. Instead, he looked at Zou Feifei's damaged nose again, and then said to her: "The reason why we are talking about this in front of you is to let you have full understanding."
The right to know and the right to choose. So now the choice is in your hands, should you choose a more radical treatment plan or a more stable treatment plan?"
Hearing Wu Hao suddenly ask her, Zou Feifei was a little confused. Facing the people who were looking around, Zou Feifei thought for a moment, then smiled at Wu Hao and said: "Mr. Wu, what are the advantages of these two treatment options? Can you
Can you introduce me to it?"
After 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 riskier and more radical treatment option, which is to replace the nose as a whole. This way, the integrity is better, no traces of repair and replacement can be seen, and you have a real nose, and even if you dislike your nose
If it's too flat, you can ask us to print it to make it stiffer.
In other words, we can make it a little more perfect."
