On the first day after surgery, in the comprehensive surgical ward, Yang Ping took everyone on rounds.

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

And these bandages do not need to be replaced, they are wrapped for 12 days before they can be removed and bandaged. Within 12 days, Mr. Sun could only urinate by urinary catheter; Stool can only be solved by bedpan in bed; Eating can only be fed, and when necessary, it may also be put on the stomach tube, the food is ground and pulped, made into semi-liquid, and injected directly into the stomach from the stomach tube.

Absolutely bedridden, lying in bed every minute and every second, even if you get out of bed once, it is not considered absolute bedridden.

It takes 10-12 days for the transplanted skin to establish a vascularity relationship with the substrate, and within 10-12 days, it needs to rely on pressure to maintain the nutrient supply of the skin, and after 10-12 days, the new vascularization between the base and the skin can be established, even if there is no external pressure, the skin can still survive, so the compression dressing can be removed at this time.

After surviving these 12 days, Mr. Sun can break out of the cocoon and become a butterfly.

In the ward, Ms. Sun's students are very enthusiastic, they take turns to take care of Ms. Sun, feed porridge and water, serve feces and urine, and share their study or work stories with Ms. Sun in their spare time.

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

Mr. Sun's lips could only move in a small area, and he said a little indistinctly: "I was stripped of a layer of skin, why didn't I feel any pain?" ”

was stripped of a layer of skin, this is a metaphorical image, I didn't expect Mr. Sun to be quite humorous, and this caused a burst of laughter.

"Don't you see that we are a painless ward, and there are signboards hanging on the walls, if you cry out for pain, won't you smash our signboards?" Yang Ping joked along with his words.

Teacher Sun immediately said, "Is the matter so serious? In this case, even if it hurts, I will endure it, and I will never ask the doctors and nurses to give painkiller injections, and I will never do anything that smashes your signboard. ”

The teacher's eloquence is good, and he can still laugh with the doctor when he becomes Mumuyin.

"You're wrong again, if you call the nurse for painkiller injections in pain, it means that our pain-relieving program has failed, and the excellent pain-relieving program is not on-demand administration, but regular and quantitative administration, not to administer pain until you are already in pain, but to administer in advance to prevent you from pain." Yang Ping took the opportunity to give him the concept of pain relief.

Regarding pain, which was not taken seriously before, now it is very important, body temperature, heart rate, pulse, respiratory rate, which are the four major vital signs, and now pain is listed as the fifth vital sign.

Therefore, many places are now promoting pain-free wards and practicing new pain-relieving concepts and programs, but most pain-free wards are still pretending to be in place, and they are not really in place, which is the same as the packaging advertisement of beef noodles, and the pictures are just for reference.

"Thank you, thank you, Professor Yang, thank you Dr. Wan Yin!" Teacher Sun said gratefully.

He was lying on the bed, very excited, hoping that the 12 days would pass soon, and he wanted to see his whole body and new himself.

Mr. Sun knew that if it weren't for Yang Ping's face, how could this world-class plastic surgeon master perform surgery on himself, and I heard that people charge millions of dollars for an operation.

"You have a good rest, the next surgery Dr. Yin Wan will give you a scalp change, hair transplantation, double eyelids, eyelash implants, I want to ask you, about hair, can you choose --- thick, thin, bald, or other desired hairstyle?"

"Can you also customize your hairstyle?"

"It's customized."

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

"Good! We've been in the lab to help you grow scalp with hair and eyelid skin with eyelashes, and by the time the surgery comes, you'll be ready to use. ”

After chatting with Mr. Sun for a while, after checking the room, Yang Ping and everyone went to the laboratory to see how the new skin piece cultivation was carried out.

When Mr. Sun performed the skin graft surgery, he had already removed some residual hair follicles from his head, and these precious hair follicles were preserved like seeds, and then implanted into the skin film in the laboratory, and then used this skin piece to amplify, and the same method was used to cultivate eyelashes.

If it weren't for the technical support of in vitro augmentation of the skin, Mr. Sun's surgery would not have been able to obtain so many skin sources, nor would it be possible to obtain such high-quality skin sources, let alone skin sheets with hair.

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

Liang Fatzi helped in the laboratory and worked as an assistant to Tang Shun, but it was just to accompany the chatter and do chores.

Tang Shun was doing it himself, putting a small piece of skin into the cultivator, and when he saw Yang Ping and everyone coming in, he immediately ended the work in hand.

"How?" Yang Ping asked him.

Tang Shun nodded with satisfaction: "According to the experimental plan, I implanted hair follicles into the skin piece, nine hair follicles were implanted at a time, the spacing was very dense, and according to our technology multiplication, it can be replicated according to the density I have now prefabricated." ”

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

"This new multiplication technology, the expanded skin is a constant copy of the raw material? It has no hair, and the enlarged large skin patches are hairless; If it has hairs or follicles, the enlarged skin will also have hairs or follicles at the same density as the source skin? Yin Wan asked after listening to their conversation.

Tang Shun replied with great certainty: "That's right, that's it, magical, right?" This principle is completely different from Professor Maninstein's technique, to be precise, he is amplification, and we are multiplication. ”

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

It's a real replication, and it's a very innovative technology.

"So, as long as there is a hair follicle, you can make a copy of a hair follicle?" Yin Wan broke the casserole and asked to the end.

Tang Shun knew that Yang Ping had no intention of hiding, so he also said: "Correct." ”

"How do you control the density of a hair follicle? Multiple hair follicles have their own density, multiplication only needs to replicate the original density, one hair follicle does not have density, how to replicate density? Yin Wan didn't understand the trick.

"It's very simple, there are only hair follicles, there is no reference for the replication of density, he has randomness, we let it multiply, and the multiplied skin sheet hair is sparse and dense, we can cut off the skin piece according to the density demand, and take this skin piece as a skin source to cultivate again." Tang Shun explained clearly.

"Ingenious!"

Yin Wan had to admire their way of solving the problem, and they were very thoughtful.

"What is here?"

Yin Wan noticed that the shape of the medium used for skin attachment during this culture period was not plate-shaped, but a spherical shape, and if you looked closely, it was the shape of the head, and then if you looked closely, this attachment medium was Mr. Sun's head model.

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

Tang Shun knew that this new technology was a mystery to Yin Wan, so he had to explain: "Isn't your next surgery going to be a scalp implant?" During the operation, you only need to put the head covering the head, and then evenly punch the holes, pull the net slightly, and then cooperate with VSD negative pressure suction, isn't it a perfect scalp transplant? ”

"Excellent! And it looks very comfortable. Yin Wan gave a thumbs up after listening to the explanation.

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

"So? Can skin grafting in complex shapes such as hands and feet be used for this prefabricated skin grafting method? Yin Wan was very excited.

In the past, he used plastic surgery to use 3D printing technology to assist, such as rhinoplasty, using 3D printing technology to print out the cartilage he wanted, and then implant it into the patient's body to achieve the desired effect.

However, there is no way to transplant skin sheets, and for some three-dimensional parts, only the method of splicing can be used to shape the three-dimensional shape of the wrapping.

As for the fact that the face can be shaped in one go, it is because the face is still relatively flat in general.

If it's a head, it's spherical, and it can't be formed at once.

It's like cutting a mask out of a piece of paper, but not a pair of gloves.

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

We're talking about technology here.

On the other side, Song Zimo, Xu Zhiliang, Auguste and Robert surrounded Liang Fatzi to learn about his recent learning from Tang Shun.
