godfather of surgery

Boss Liao washed two apples, one for each of him and Mr. Sun.

"I especially admire you guys who are brave and brave. If it wasn't for a hero who saved my life when I was young, I would still be sitting here now. But until now, I don't know who saved me. Teacher Sun, you said that you were so Big fire, if I'm too scared to go in, why are you so courageous?" Boss Liao chatted while eating apples.

Teacher Sun smiled calmly: "I can't talk about any heroes. The situation was critical at the time, and I didn't think too much about it. I only knew that there were more than a dozen students inside. If I didn't go in and rescue them, the dozen or so dolls would be gone."

"My students must come here, some of them will arrive tomorrow." Teacher Sun thought of his students.

Some of these students have good academic performance and have been admitted to prestigious universities, while some have poor grades and go to work after graduating from high school.

No matter what they do after graduation, these students have always kept in touch with Mr. Sun, and they will organize a group to visit Mr. Sun with gifts every Spring Festival.

"Let them come, and they should come." Boss Liao said.

At this time, there was a knock on the door. Teacher Sun and Boss Liao saw that it was Professor Yang at the door.

Yang Ping has seen Mr. Sun many times, not only asked about the medical history repeatedly, but also checked the body many times to provide a basis for perfecting the operation plan.

"The small piece of skin we took from you has now expanded to two square meters, which is enough skin for surgery. I will take you to have a look when I have time?"

Yang Ping came in and told Teacher Sun.

"Just a piece of skin the size of a fingernail can become two square meters?"

Teacher Sun was very surprised. Is the technology so advanced now?
At the same time, Mr. Sun has a strong curiosity about this piece of skin. He heard Yang Ping say that he can go and have a look. Of course, he will not let go of this opportunity.

"You are the first patient of our new technology, so let you participate in the whole process and experience the whole process. You wait for our arrangement and let you go to the laboratory to see the skin." Yang Ping said.

Teacher Sun understands that Dr. Zhang Lin told him that this new technology cannot be done at any cost.

Teacher Sun's surgery plan, simply put, is to change the skin.

Cut off all the scars on the whole body and replace them with normal skin. This is a routine operation in the burn department.

The scars are inelastic and contracture, which limits the movement of the joint.

The scar is not resistant to friction, and it is easy to wear out and form ulcers at the site of repeated friction.

Scars have no pores and cannot perspire, which seriously affects the body's heat dissipation.

Of course, severe adverse appearance of the scar is also the purpose of surgery.

After human tissue is damaged, very few tissues can be repaired by the original tissue, such as fracture healing, which is completely repaired by bone tissue. This repair method is the most perfect.

However, the repair of most tissue damage is completed by a small amount of original tissue and most of the scar tissue, such as the repair of skin wounds.

For skin replacement surgery, there must be a donor area for skin grafts. The so-called donor area is the place where skin raw materials are provided.

If the area is not large, it’s okay, you can take the skin from the healthy part, and tear down the east wall to make up the west wall.

For extreme cases of full-body scar formation like Mr. Sun, the scalp is generally used as the donor site for raw materials.

The scalp has good blood circulation. After cutting the thin layer of skin, it can quickly return to its original state. In this way, when the scalp recovers, you can continue to cut it, just like cutting leeks. After falling off, it will grow taller next time, continue to cut, and can be cut repeatedly. In this way, the limited scalp becomes an unlimited supply area for skin raw materials.

Except for the scalp, there is no such good raw material supply area.

The skin in other parts is not as good as the scalp, the recovery is not as fast as the scalp, and it cannot be fully recovered like the scalp, so the effect of cutting leeks cannot be achieved.

In addition to skin replacement, Mr. Sun's surgery would be even better if plastic surgery was added to the burnt mouth, nose, and ears, and it would be even more perfect.

There is a very close relationship between plastic surgery and burns, and many plastic surgeons came from the burns department halfway through their careers.

Director Chi of the burn department worked very hard this time. He went to the General Surgery Department to help take care of the patients and prepare for the operation.

After all, he has a lot of experience, and he is much more sophisticated than those boys in general surgery.

In short, Director Chi wants to follow Gao Yuan's path completely.

"How big is the skin now?" Director Chi asked Zhang Lin.

"At least two square meters, the area has not been measured today." Zhang Lin was triumphant.

When Director Chi heard that the stem cell laboratory had successfully amplified the skin, he was very excited. With this technology alone, Sanbo's burn department could become a hit.

Since the experiment started, Director Chi has never gone in to see it.

Because after Tang Shun became the director, he introduced an advanced management model to the laboratory. Except for the researchers of the laboratory, other personnel must be approved for entry and exit.

This ensures that the experiment will not be disturbed, and it will prevent technology leakage.

The surface area of ​​ordinary human skin is only 1.5-2 square meters. This huge piece of skin is enough for surgery, and after a few days of expansion, there is still a lot of surplus.

Director Chi wanted to go to the laboratory to see this miraculous piece of skin, so he asked Zhang Lin: "Can I enter the laboratory to see this piece of skin?"

"It should be no problem to ask Dr. Tang about this. You are the director of this hospital, and the patient is also yours. You are also a member of the laboratory." Zhang Lin didn't dare to decide.

Hearing that he was also a member of the experiment, Director Chi immediately sat up straight, found a computer, and looked at Teacher Sun's preoperative examinations one by one like a resident doctor.

August, Robert, Director Chi, and Teacher Sun followed Yang Ping to the stem cell laboratory.

Tang Shun was leading a few graduate students to conduct experiments. Everyone was talking and laughing, and the atmosphere was not serious at all. It seemed that Tang Shun had adapted to this relaxed laboratory atmosphere and agreed with it.

The weather in the south is relatively hot. In this kind of weather, Tang Shun didn't bother to wear a suit and leather shoes. Instead, he wore a T-shirt, big shorts and slippers, which was much more relaxing.

Tang Shun asked Li Guodong to open the transparent incubator, put on gloves, fish out the skin inside, and spread it on the platform next to it.

The mouths of August and Robert opened into an O-shape. In just two weeks, a piece of skin of 1 square centimeter expanded to two square meters.

No wonder Professor Yang is not interested in Langerfer's surgery. It turns out that he has mastered the skin augmentation technique in vitro, and the quality of the expanded skin is no worse than Langerfer's technique.

August and Robert knew that Maninstein's induction formula was kept strictly confidential, and it was impossible for Yang Ping to obtain it. It must be Professor Yang's own formula. During this time, August and Robert had been by Yang Ping's side, I've never seen him experiment in this area.

Now, if you just take out an induction formula, you can actually succeed in one experiment.

This kind of miracle is always unacceptable, including Tang Shun.

Tang Shun is considered a top talent in the world, and he has never seen this kind of experiment succeed in one attempt.

There is only one explanation. Professor Yang has done experiments in this area before, and now this induction formula has been confirmed by many experiments.

Tang Shun calculated the time. Professor Yang is so young and has the technology of spinal external fixation before. It is impossible to produce so many world-class achievements in a short period of time.

Medical genius!

It can only be explained that way.

Teacher Sun couldn't believe it. This piece of skin was the size of a fingernail cut out of his own perineum. The two-square-meter piece of skin was spread on the platform, and it had a great visual impact.

is this my skin

Can all my scars be cut off in the future and replaced with this kind of skin?
Teacher Sun was so excited that he couldn't help crying.

"If you take a piece of scalp with hair and enlarge it like this, will the skin covered with scalp be enlarged and then transplanted to the head of the alopecia patient, will the effect be better than hair transplantation?" Zhang Lin said on the side.

"If Duan Baldhead is so stubborn, he will not be able to expand it even if he wants to." Xiao Wu continued.

Tang Shun looked at the skin and said, "You're right, one result can produce many results, and in the future, the formula can be induced to improve. Even if it's bald and bare, it can induce hair follicles and hair."

"If you launch this technology, you can directly use me as an experiment and push my hairline forward." Zhang Lin touched his forehead where the hairline was slightly higher.

Yang Ping said with a smile: "The further back the hairline is, the more knowledgeable you are, especially Mr. Zhang, who manages students without such a hairline, so you can't support your aura."

Seems to make sense.

Zhang Lin touched his forehead again.
