Chapter 700 Three-dimensional skin forming technology

On the first day after the operation, Yang Ping led everyone to round the ward in the general surgery ward.

Teacher Sun was wrapped in bandages except for his eyes and mouth. Of course, the excretion terminal was also wrapped.

Moreover, these bandages do not need to be replaced, and they have been wrapped for 12 days before they can be removed. Within 12 days, Mr. Sun can only urinate with a catheter; defecate with a bedpan on the bed; eat with feeding, and if necessary, a gastric tube may be used to grind and beat the food into a semi-liquid form, which is directly passed from the stomach. The tube is injected into the stomach. In short, eating and drinking can only be done in bed. This is the so-called "absolute bed rest".

Absolute bed rest, lying in bed every second, even getting out of bed once, is not considered absolute bed rest.

The transplanted skin graft needs 10-12 days to establish a blood supply relationship with the base. Within 10-12 days, it needs to rely on pressure to maintain the nutrient supply of the skin graft. After 10-12 days, the new blood vessels between the base and the skin graft are established. The graft will survive without external pressure, so the compression dressing can be removed at this point.

After these 12 days, Teacher Sun will be able to break out of the cocoon and become a butterfly.

In the ward, Mr. Sun's students are very enthusiastic. They take turns to take care of Mr. Sun, feeding porridge and water, carrying excrement and urine, and sharing their studies or work stories with Mr. Sun in their spare time.

"Ms. Sun, how is it? Does it hurt?" Yang Ping asked with concern.

Teacher Sun could only move his lips in a small area, and said vaguely: "I was skinned, why didn't I feel any pain?"

With the first experience, Tang Shun now has no doubt that the experiment will be successful.

Regarding pain, I did not pay much attention to it before, but now I attach great importance to it. Body temperature, heart rate, pulse, and respiratory rate are the four major vital signs, and pain is now listed as the fifth major vital sign.

"Thank you, everyone, Professor Yang, and Dr. Iwan!" Teacher Sun said gratefully.

This is true replication, and the innovation of this technology is very great.

However, there is no way for skin grafts to do this. For some three-dimensional parts, splicing can only be used to shape the three-dimensional shape of the package.

"Why is that?" Ivan pointed to the medium of the head model.

"It's custom made."

If it's a head, this kind of spherical shape cannot be formed at one time.

"So? This prefabricated skin graft method can be used for skin grafts with complex shapes such as hands and feet?" Ivan was very excited.

If Mr. Sun's surgery hadn't been supported by in vitro skin augmentation technology, there would be no way to obtain so many skin sources, nor would it be possible to obtain such high-quality skin sources, let alone obtain skin grafts with hair.

Ivan had to admire their ideas for solving problems, which were very thoughtful.

"Didn't you see that we are a pain-free ward, and there are signboards on the walls. If you cry out for pain, wouldn't you smash our signboard?" Yang Ping joked along with his words.

"It's very simple. There are only hair follicles. There is no reference to the density replication. It has randomness. We allow it to multiply. The hair of the multiplied skin can be sparse or dense. We can cut the skin according to the density. Take this The skin is used as a source of skin to grow again." Tang Shun explained clearly.

"Can the hairstyle be customized?"

In the past, he often used 3D printing technology to assist in plastic surgery, such as rhinoplasty, using 3D printing technology to print out the cartilage he wanted, and then implanted it into the patient to obtain the expected effect.

The harvest of this trip to China is really great, much bigger than expected.

Fatty Liang was helping Tang Shun in the laboratory as an assistant, but it was just doing odd jobs with him.

Being skinned, this metaphor image, I didn't expect Mr. Sun to be quite humorous, and this remark caused a burst of laughter.

When Mr. Sun performed the skin grafting operation, he had already removed some residual hair follicles from his head. These precious hair follicles were preserved like seeds, and then implanted into the skin in the laboratory. The skin is expanded, and the eyelashes are cultivated in the same way.

The teacher's eloquence is good, and he can still joke with the doctor when he becomes a mummy.

Tang Shun was doing it himself, putting a small piece of skin into the incubator. When he saw Yang Ping and everyone coming in, he immediately finished his work.

Ivan noticed that the shape of the medium used for the attachment of the skin flap during this culture period was not flat, but a spherical shape. If you look carefully, it is the shape of the head. If you look carefully, the attachment medium It is Mr. Sun's head model.

Teacher Sun knew that if it weren't for Yang Ping's face, how could this world-class plastic surgery master perform surgery on himself. I heard that he charges several million dollars for a surgery.

Tang Shun replied very positively: "That's right, that's it, magical, right? This principle is completely different from Professor Maninstein's technology. To be precise, he is amplification, and we are multiplication."

"How does one hair follicle control the density? Multiple hair follicles have their own density. To multiply, you only need to copy the original density. A hair follicle does not have density, so how to copy the density?" Ivan didn't understand the technique.

"How?" Yang Ping asked him.

As for the face can be shaped at one time, it is because the face is generally relatively flat.

He was lying on the bed, very excited, and hoped that the 12 days would pass quickly. He really wanted to see his new skin, his brand new self.

"This new multiplication technology, the amplified skin is a continuous copy of the original material? It has no hair, and the amplified large-scale skin has no hair; if it has hair or hair follicles, the amplified skin will also have no hair. Will it have hair or follicles with the same density as the source skin?" Ivan asked after listening to their conversation.

"Then you still need to pick it. It's thick and thick. If you come, you're welcome."

Teacher Sun immediately said: "Is the matter so serious? In this case, even if it hurts, I will endure it. I will not ask doctors and nurses to give painkillers. I must not do anything to ruin your brand."

"You have a good rest. Dr. Ivan will change your scalp, hair transplant, double eyelids and eyelashes for your next operation. I want to ask you now. Regarding your hair, you can choose - thick, thin and bald. , or other desired hairstyles?"

"You are wrong again. If you are in pain and call the nurse for pain relief injections, it means that our pain relief plan has failed. An excellent pain relief plan is not to give medicines on demand, but to give them regularly and quantitatively. It’s about giving medicine in advance to prevent you from having pain.” Yang Ping took the opportunity to give him a scientific introduction to the concept of pain relief.

Ivan took a deep breath and repeatedly pondered the word "copy" in his heart.

Tang Shun nodded with satisfaction: "I implanted hair follicles into the skin according to the experimental plan. Nine hair follicles were implanted at a time. The spacing is very dense. According to our technology, it can be replicated according to the density I have prefabricated."

Therefore, many places now promote pain-free wards and practice new pain-relieving concepts and solutions, but most pain-free wards are still pretending, and they are not really in place. This is the same as the packaging advertisement of beef noodles, and the pictures are just for reference.

"It's great! And it looks very comfortable." Ivan gave a thumbs up after listening to the explanation.

After chatting with Teacher Sun for a while, Yang Ping and everyone went to the laboratory to see the cultivation of new skin grafts.

Tang Shun knew that Yang Ping had no hidden intentions, so he also confessed: "Correct."

Tang Shun knew that this new technology was full of mysteries to Ivan, so he had to explain: "Don't you want to have a scalp transplant in your next operation? With this kind of attachment medium, the skin will grow along the model, and finally It forms a headgear-like shape. During the operation, you only need to cover the head with the headgear, and then evenly punch holes, pull the mesh slightly, and cooperate with VSD negative pressure suction, isn’t it a perfect scalp transplant?”

"So, as long as there is one hair follicle, you can duplicate a hair follicle?" Ivan broke the casserole and asked.

After checking the room, everyone came to the laboratory again.

"Okay! We have already cultivated the scalp with hair and the eyelid skin with eyelashes in the laboratory, and it will be almost ready for use when the surgery is performed."

"clever!"

"What's here?"

This principle is like not using cutting and splicing technology. A mask can be cut out with a piece of paper, but a pair of gloves cannot be cut out.

This skin forming technology is the real three-dimensional forming technology.

Technology is being discussed here.

On the other side, Song Zimo, Xu Zhiliang, August and Robert surrounded Fatty Liang to learn about his recent study experience with Tang Shun.
