Chapter 369: Walking in the sun

Chapter 369 Walking in the Sun
Allogeneic transplantation with an anti-rejection gene is simple. Piglet skin and piglet skin with activity are induced by implanting various factors to make it appear to have genes for human skin. The perfect combination of the human body.
In a simple sentence, Professor Li Housen and his team have been fighting for almost ten years. When they returned from the United States that year, they began to study. He didn't do as well as Korean-American brothers and sisters during surgery. However, his strength lies in research. Finally, I was a little bit brow, and the clinical promotion was not open. Really, Lao Li's heart was broken.
"Little curette, syringe."
Facial repair started, and the slightly pale skin was once again gently scraped along the texture with a spatula by Zhang Fan, and his own mucous membrane and fat transplantation must be performed first.
Scalding is too abominable. It is not like a knife and axe, it goes straight, but it is a very complex compound injury.
After removing the burned tissue, the wounded area was a lot of pits of different sizes, just like the ground on the battlefield bombarded by shells, as was the face of the wounded.
"Open the mouth." Lu Shuyan opened the patient's mouth with an opener without disorder. Zhang Fan left-handed syringe and right-handed scalpel. While rinsing, use a scalpel to start selecting materials along the mouth.
The wounded had serious facial injuries. Fortunately, the eyes and nose were preserved, but the lips were directly burnt like shrunken plastic.
This place is not repaired, it will only get tighter in the future. Because the texture of the muscle around the mouth is a ring-shaped muscle, in fact, it is rougher, and the structure of this place is similar to that of the anus. There is also a rosy lips.
Do what you do best, this is Zhang Fan's belief. The mucosa in the mouth was chosen to create a new rosy lips.
This mucosa must be provided by itself, and there are very few places to take materials. Only the oral cavity and the (a) can supply limited mucosa, so for male patients, it can only succeed once, otherwise there is no place to take materials.
"Trim hemostatic cotton." Zhang Fan cut a rectangle with a scalpel, carrying the mucous membrane of the vascular pedicle. "Needle holder to absorb the thread." Suture the mouth.
"Bao Yin, put the mucous membrane into the curved plate and pour the physiological fluid." Zhang Fan explained.
"it is good."
After the mucous membranes are placed, the fat is followed. The best place for fat transplantation is the fat in the abdomen. The fat in other places is too dense and easy to liquefy and necrosis. Taking fat is too easy. Open the skin and cut it with a scalpel. After cutting, suture directly.
Fix it first, in fact, simply dig the east wall to fill the west wall. Lu Shuyan was almost pinching her hands. The girl can't see fat now, especially this kind of very fat belly.
After preparing the materials, Zhang Fan began to repair the crater-like face, and filled it with fat first. Fat transplantation was very strange. The fat taken from the abdomen was put elsewhere and would be absorbed.
And the absorption is very powerful, as if it was eaten by the body, it can reach almost 30% of the filling volume, so when the filling is not too large, the fat must be filled, and it must be adjusted to prevent future absorption, without adjustment, etc. transplantation After the pig's skin, it collapsed. The bigger the pit, the worse the collapse.
Professor Li Hosen and Professor Yan Dehua watched Zhang Fan proceed in an orderly manner, and the originally raised heart was slightly lowered.
Although they did not speak, they glanced at each other. The meaning is clear: "From the current method, it is not a mallet!"
Fat transplantation has a liquefaction process. The larger the fat area, the more severe the liquefaction, because the larger the area, the more fat cells are broken. Therefore, it is best to extract the fat beads under the microscope, which is 4-6mm. The earliest use of this is the Korean beauty industry.
Fill the pits and fill them one by one with fat. The face that was originally torn by Zhang Fan's shaved blood seemed to stick to the cream of the birthday cake, piece by piece. It is exactly the same, all white and raised.
It's really like a person with blood on his face, and then he is covered with pieces of birthday cake.
After filling, begin to cover allogeneic skin. The time has come to show the technology, especially Professor Li Housen, almost holding his breath.
In the large conference room outside the operating room, a group of Da Na whispers in the Northwest transplantation community whispered. The leaders who had watched it for a while and left, too boring to read! These experts are left.
"Lao Chen, yes, your undergraduates in Lanzhou are so great. It's only a few years since I graduated, so skilled."
"Crap, what do you think."
"Shameless stuff, it's like your student." The other party couldn't chat. The professor who spoke was a little angry, and his belly was vilified.
In fact, his tone was a bit of contempt for Lan City, after all, he leaned more south.
"It's okay, just look at the next step. In this step, even a doctor in our department can do it." A director of the Army Hospital said to the Air Force doctor nearby.
"Ok!"
The pink pigskin, which is still unconceived, is a bit swollen after being soaked with various potions, and curls together as if it has been soaked in Guotan.
"Alice pliers, four. Director, come and help me pull it off, Lu Shuyan, slowly spread it out, don't use too much force." The pigskin with the vascular pedicle is too thin and said too hard May be broken.
When the pigskin was opened, Professor Li Housen's heart almost popped out of his throat. If this step is not done well, you don't need to expect anything, the latter will not do it.
The strength of the three people is equal. "Come, slowly go down, come, slow, not in a hurry, come to the left, come, let go." Zhang Fan is also nervous, the assistant in the system can do whatever you say, but Not in reality.
"The ophthalmic forceps are fast, fast." The position is good, completely covering the wounded's face. Look down from the shadowless lamp at this time. Just like a faceless person, his eyes, nose and lips are all covered.
Fixed, Zhang Fan moves faster and faster. After the pigskin is detached from the physiological fluid, if the circulatory system cannot be quickly connected, this thing will be necrotic.
To start the operation under the microscope, first establish a channel. Allogeneic transplantation cannot damage the inner layer of human blood vessels, because various signal factors will burst after injury, and once exposed to the human body, it will become a battlefield.
Under a microscope, the hemostat and the hemostat are opposed to each other, pinching the blood vessel of the human body, and pulling off the outer mold of the blood vessel. Human blood vessels can be roughly divided into three layers. The inner layer of the membrane is home to 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 dull, and the outer layer becomes sensitive again. The inner layer cannot be destroyed. Once it is destroyed, it can release various factors, transfer various soldiers, the outer layer can be destroyed, and the outer layer of the interface can be pulled away. .
Then insert this non-skinned blood vessel head into the blood vessels of the piglet's skin. The muscle layer of the human blood vessel is attached to the inner layer of the pig's blood vessel. The muscle layer does not matter, as long as there is clothing to wear.
Then there is suture. The difficulty comes. At this time, the suture must penetrate the pig's blood vessels through the vascular muscle layer of the human body, but cannot pass through the inner layer. It is really a snail shell to do the dojo. There are no hundreds. Thousands of times of training, when no muscle memory is developed, who dares? Who can? .
Click the seam, move forward a little bit. Zhang Fan's slow breathing and countless exercises in the system have already allowed him to have a feeling of breaking through the blood vessels. This was exchanged for countless hypoglycemia symptoms. Come.
Not to mention that the doctors who performed the operation were afraid to come out, even Professor Li Housen and Professor Yan Dehua who stood by the side of the operation did not dare.
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: "That's it, this is it."
"It's too stable!" The experts in the conference room saw the poison one by one, and they saw it when they started suture.
"Yeah, it's too stable, but I don't know how long it can last. The time required for this operation is not one or two hours. Hey ~!"
At this time, the blood vessels are like two intersecting rubber tubes, one over the other, and the front is sutured first, and then the other side is sutured over 180 degrees.
Zhang Fan lifted the adventitia of blood vessels. On a blood vessel with a diameter of less than 1mm, if the fracture is calculated according to this clock face, it should be stitched before 12 o'clock, and then stitched at the opposite 6 o'clock.
The third stitch is stitched at 2 o'clock, the fourth stitch is stitched at 4 o'clock, flipped, the fifth stitch is stitched at 8 o'clock, and the last stitch is stitched at 10 o'clock. Each suture has to go through the blood vessel twice, which is really difficult. It is just like smoking in a gas station. Suddenly it can explode.
Every time you sew, the bean sweat comes out once. It is really difficult to control the force and the continuous output force. The left and right hands must cooperate very cleverly. Once stitched, Zhang Fan had to stop rubbing his sweat once to allow the muscle energy to recover slightly.
"Dextrose!" Zhang Fan felt a little dizzy. It took more than three hours for the skin on the face to reach the lower jaw. After a greedy sip of high concentrations of glucose, continue.
Small blood vessels, small nerves, and microlymphatic vessels, one is more difficult to handle and the other is more complicated than one. The blood vessels do not sew the skin, the nerves do not sew for a long time, the skin atrophies, and the lymph is not sutured.
What else can you do, liver. Everyone inside and outside the operating room was worried. The more hopeful, the more worried. The better Zhang Fan performed, the more worried everyone became.
Repair and reconstruct the eye socket, apply the texture to the nasal cavity, repair the lips, step by step. Slowly the original face became acceptable.
"Open the hemostat!" Instantly, the blood entered the allogeneic skin through the repaired pipeline, and the original piglet skin became bloody.
"How's that?" Professor Li Hosen's dry throat asked quietly, and his heart was so uncomfortable.
"It should be possible." Zhang Fan looked at his masterpiece and said slowly, in the future, although he could not see a bright smile, he could not see any rich expressions. However, he can walk in the sun and face the world happily.
Ladies and gentlemen, not Lao Zang,
It ’s not short,
It's true that the liver is not moving!
I'm not watery, I'm not gibberish,
Just serious step by step.
