Allogeneic transplantation with anti-rejection genes is simply to induce the piglet, which has active piglets, to make it look like it has the genes of human skin, and then implant them into the human body, so that they can be perfectly combined with the human body.

In a simple sentence, Professor Li Housen and his team have been working hard for almost ten years, and when they returned from the United States, they began to start research. Surgery, he didn't do as well as his Korean-American brothers. However, his strength lies in research. Finally, it was a little eyebrow-raising, but the result could not be promoted clinically, really, Lao Li's heart was broken.

"Small curette, syringe. ”

At the beginning of facial rejuvenation, the originally slightly pale skin was gently scraped by Zhang Fan along the texture with a curette again, and his own mucosa and fat grafting must be carried out first.

The scald is so hateful, it's not like a knife and axe, straight to the point, but a very complex compound damage.

After the scalded tissue was removed, the wounded area was filled with craters of various sizes, like the ground on the battlefield that had been bombarded by artillery shells, and the wounded man's face was like this.

"Open your mouth. Lu Shuyan used the opener to open the patient's mouth without disorder. Zhang Fan has a syringe in his left hand and a scalpel in his right hand. While rinsing, use a scalpel to start selecting materials along the mouth.

The wounded man's face was badly damaged, but fortunately, his eyes and nose were saved, but his lips were burned like rotten plastic shrunken together.

If this place is not repaired, it will only shrink more and more in the future. Because the texture of the perioral muscles is a ring of muscles, in fact, to put it a little rougher, the structure of this place is similar to the structure of the anus. There is also a rosy lip.

If you want to do it, you will do your best, this is Zhang Fan's belief. The mucous membranes in the mouth are chosen to create a new rosy lip.

This mucosa must be provided autologously, and there are very few places to collect materials, only the oral cavity and the vaginal (a) tract can supply a limited amount of mucosa, so for male patients, it can only be done once, otherwise there is no place to collect materials.

"Hemostatic cotton. "The cheeks of the mouth were cut off with a scalpel by Zhang Fan a rectangular mucosa with a vascular pedicle. "Needle holder, absorbable thread. "Stitch up the mouth.

"Bao Yin, put the mucous membrane into the curved disc and pour in the physiological fluid. Zhang Fan explained.

"Good. ”

After the mucosa is placed, the fat is next. The best place for fat grafting is the fat in the abdomen, and the fat in other places is too dense and easy to liquefy and necrosis. It is too simple to take the fat, open the skin, cut it with a scalpel, and suture it directly after cutting.

Repair first, in fact, it is simply to dig the east wall and make up the west wall. Lu Shuyan was about to pinch her hands, and the girl couldn't see fat now, especially this kind of fat meat with a very fatty abdomen.

After preparing the materials, Zhang Fan began to repair the crater-like face, first filling it with fat, which is very peculiar, and the fat taken from the abdomen is put elsewhere and will be absorbed.

And the absorption is very strong, as if eaten by the body, it can reach almost 30% of the filling volume, so when filling, you can't fill the pit with as much fat as it gets, and it must be adjusted to prevent future absorption. The bigger the pit, the more it collapses.

Professor Li Housen and Professor Yan Dehua watched Zhang Fan carry out the operation in an orderly manner, and the heart that was originally lifted was slightly lowered.

Although the two did not speak, they looked at each other. The meaning is clear: "Judging from the current method, it is not a mallet!"

Fat grafting has a liquefaction process, the larger the fat area, the more serious the liquefaction, because the larger the area, the more broken fat cells, so it is best to extract the fat beads in the microscope, how big this thing is, 4-6mm. The first to use this was in the Korean beauty industry.

Fill the pits, fill them one by one with fat, and the face that was originally shaved by Zhang Fan was torn by blood, as if it was sticking to the cream of the birthday cake, piece by piece. It's really exactly the same, it's all white, it's all raised.

It's really like a person with a bloody face, and then it's pasted with a piece of birthday cake.

Once filled, begin to cover the allogeneic skin. The time has come to show the technology, especially Professor Li Housen, who is about to hold his breath.

In the large conference room outside the operating room, a group of leaders in the Northwest transplant community whispered in a low voice, and the leaders who were originally watching watched for a while and then left, it was too boring to understand!

"Lao Chen, it's okay, your undergraduates in Lan City are so awesome. It's only been a few years since I graduated, and I'm so skilled. ”

"Nonsense, what do you think. ”

"Shameless thing, like it's your student. "The other party can't chat, and the professor who spoke was a little angry, and he was full of slander.

In fact, his tone is a little despised for Lan City, after all, he is a little closer to the south.

"It's okay, it depends on the next step, this step can be done by any doctor in our department. A director of the army hospital said to the Air Force doctor next to him.

"Hmm!"

The pink pigskin, estimated to be a little pigskin that has not yet been confined, has been soaked in various potions and is a little swollen, curled together as if it is a fruit dan skin that has been soaked in water.

"Alice pliers, four. Director, come and help me pull it away, Lu Shuyan come, slowly stretch it out, don't use too much force. "The little pigskin with the blood vessel pedicle is too thin, and if you use too much force, you may be broken.

When he opened the pigskin, Professor Li Housen's heart was about to jump out of his throat. If you don't do this step well, you don't have to expect anything, let alone do it later.

The strength of the three people is equal, "Come, slowly down, come, slow, not in a hurry, come to the left, come, put." Zhang Fan is also nervous, he can do whatever the assistant in the system says, but not in reality.

"Ophthalmic forceps fixation, fast. "The location was good, it was completely covered in the face of the wounded. At this time, look down from the shadowless lamp. Just like a faceless man, his eyes, nose, and lips were all covered.

Fixing, Zhang Fan's movements are getting faster and faster, after the piglet's skin is separated from the physiological fluid, if it can't be quickly connected to the circulatory system, this thing will die.

Start the operation under the microscope and establish the channel first. Allogeneic transplantation cannot damage the inner layer of the human blood vessels, because after the injury, various signaling factors will burst out, and once the human body is exposed, it will become a battlefield.

Under the microscope, the hemostat and the hemostat are opposite, pinch the blood vessels of the human body, and pull off the outer mold of the blood vessels. The blood vessels of the human body can be roughly divided into three layers, the inner membrane is inhabited by a large number of factors, the middle layer is the muscle layer, and the outer layer.

The inner layer is the most sensitive, the middle layer is the most sluggish, the outer layer becomes sensitive, the inner layer can not be destroyed, once destroyed, it can release various factors, transfer all kinds of generals, the outer layer can be destroyed, pull off the outer layer of the interface.

Then stuff this blood vessel head without outer skin into the blood vessels of the piglet's skin, and the muscle layer of the human blood vessel is attached to the inner layer of the piglet's blood vessels, and the muscle layer doesn't matter, as long as there are clothes to wear.

Then there is the suture, the difficulty comes, at this time, the suture, not only to penetrate the blood vessels of the pig through the human blood vessel muscle layer, but not through the inner layer, is really a snail shell to do the dojo, there are no hundreds of times of tempering, there is no muscle memory, who dare? Who can?

A little bit of a sew, a little bit of forward. Zhang Fan breathed slowly, and the countless exercises in the system had already made him feel like he had broken through the blood vessels, which was exchanged for countless hypoglycemic symptoms, which was exchanged for various Xuantian dizziness.

Not to mention that the doctors who did the operation did not dare to come out, even Professor Li Housen and Professor Yan Dehua, who were watching from the side of the operation, did not dare to come out.

Although they couldn't see the specific operation, looking at Zhang Fan's super stable hands, Professor Li Housen's face turned red, and he kept shouting in his heart: "That's it, that's it." ”

"It's so stable!" the experts in the conference room saw one by one more poisonous, and when they began to stitch up, they could see it.

"yes, it's so stable, I just don't know how long it will last, and the time required for this operation is not an hour or two. Hey~!"

At this time, the blood vessels are like two intersecting rubber tubes, one is sleeved over the other, and the front side is sutured first, and then the other side is sutured over 180 degrees.

Zhang Fan lifted the adventitia of the blood vessel, and on the blood vessel with a diameter of no more than 1mm, if the fracture was calculated according to this clock face, it should be sutured at 12 o'clock first, and then sutured at 6 o'clock on the opposite side.

The third stitch at 2 o'clock, the fourth stitch at 4 o'clock, flip, the fifth stitch at 8 o'clock, and the last stitch at 10 o'clock. Each stitch has to go through the blood vessels twice, which is really difficult, just like smoking in a gas station, you can make an explosion in one breath and one exhale.

Every time I sew it, the sweat of the bean will come out once, and it is really difficult to control the force, to control the continuous output of the force, and the left and right hands must be quite cleverly coordinated, as crisp as the inner membrane of a raw egg. After sewing once, Zhang Fan had to stop wiping his sweat once to recover the energy of his muscles a little.

"Glucose!" Zhang Fan felt a little dizzy, and it took more than three hours for the skin on his face to reach the jaw. After taking a greedy sip of high-concentration glucose, he continued.

Small blood vessels, small nerves, microscopic lymphatic vessels, one more difficult to deal with, one more complex than the other. The blood vessels do not suture, the skin is not active, the nerves are not sutured for a little longer, the skin atrophies, and the lymph is not sutured in the later stage, which is never-ending swelling.

What else can I do, liver. Everyone inside and outside the operating room was worried. The more hopeful, the more worried. The better Zhang Fan performs, the more worried everyone is.

Repair and reconstruct the eye sockets, follow the texture of the nasal cavity, repair the lips, step by step. Slowly, the original bloody face became acceptable.

"Open the hemostat!" In an instant, the blood entered the allogeneic skin through the repair pipe, and the originally pale piglet's skin became bloody.

"How's it going?" Professor Li Housen's dry throat asked quietly, his heart clenched together, so uncomfortable.

"It should work. Zhang Fan looked at his masterpiece and said slowly, although he can't see a bright smile or a rich expression in the future. However, he can walk in the sun and face the world happily.
