Chapter 368-Walking in the Sun
Allotransplantation implanted with anti-rejection genes is simply to introduce pig skins and active pig skins by implanting various factors to make it appear to have the genes of human skin, and then plant them on the human body to let them interact with The perfect combination of the human body.
In a single sentence, Professor Li Housen and his team have been struggling for almost ten years. They returned from the United States that year and began to study.He did not perform as well as the Korean-American brothers.However, his strength lies in research.Finally a bit of eyebrows, but the results can not be promoted clinically, really, Lao Li's heart is broken.
"Little curette, syringe."
Facial restoration began, and Zhang Fan's originally slightly pale skin was gently scraped along the texture with a curette again. The mucous membrane and fat transplantation must be performed first.
The scald is too hateful. It is not like a knife, chopping and axe, going straight forward, but a very complex compound injury.
After removing the scalded tissue, the wounded area is a lot of pits of different sizes, just like the ground bombed by shells on the battlefield, the wounded face is like this.
"Open the mouth." Lu Shuyan opened the patient's mouth with the mouthpiece without any disorder.Zhang Fan has a syringe in his left hand and a scalpel in his right hand.While rinsing, use a scalpel along the mouth to start selecting materials.
The wounded’s face was severely injured. Fortunately, his eyes and nose were preserved, but his lips were directly scalded like rotten plastic shrinking together.
If this place is not repaired, it will only become tighter in the future.Because the texture of the perioral muscles is a circle of circular muscles, in fact, it is rougher, the structure of this place is similar to the structure of the anus.There was also a rosy lips.
To do the best, this is Zhang Fan's belief.The mucous membrane in the mouth is chosen to create a new rosy lips.
This mucosa must be provided by the body, and there are very few places to collect materials. Only the oral cavity and vagina (a) can supply limited mucosa. Therefore, for male patients, it can only succeed once, otherwise there is no place to collect materials.
"Hemostatic cotton." Zhang Fan used a scalpel to cut off a rectangular mucosa with a vascular pedicle on the cheek of the mouth."Needle holder, absorbable thread." Suture the mouth.
"Baoyin, put the mucous membrane in the curved plate and pour the physiological fluid." Zhang Fan confessed.
"it is good."
After placing the mucous membrane, fat is next.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 die.It's too easy to take fat. Open the skin and cut it with a scalpel. After the cut, you can suture it directly.
Repair first. In fact, it simply means digging the east wall to make up the west wall.Lu Shuyan was about to pinch her hands green, and the girl couldn't see fat right now, especially this kind of very fatty belly.
After preparing the materials, Zhang Fan began to repair the crater-like face, filling it with fat first. Fat grafting is very strange. The fat taken from the abdomen is put in other places and it will be absorbed.
And the absorption is very strong, like being eaten by the body, it can almost reach 30% of the filling volume, so when filling, the pits that cannot be too large are filled with as much fat. It must be adjusted to prevent future absorption. No adjustments are made, waiting for transplantation. After the pig skin, it collapsed.The bigger the pit, the more it collapses.
Professor Li Housen and Professor Yan Dehua watched Zhang Fan orderly proceed with the operation, and the heart that had been raised was slightly lowered.
Although the two did not speak, they glanced at each other.The meaning is clear: "From the current approach, it's not a club!"
Fat transplantation has a liquefaction process. The larger the fat area, the more serious the liquefaction. Because the larger the area, the more fat cells will be damaged. Therefore, it is best to extract the fat beads under a microscope. The size is 4-6mm.The first use of this is the Korean beauty industry.
Filling the pits, filling them with fat one by one, the bloody and torn face originally scraped by Zhang Fan, seemed to be glued with the cream of a birthday cake, piece by piece.It's exactly the same, all white, all raised.
It's really like a person with blood on his face, and then he is battered with pieces of birthday cake.
After filling, begin to cover the foreign body skin.It's time to show off the technology, especially Professor Li Hoosen, almost holding his breath.
In the large conference room outside the operating room, a group of northwestern transplantation professionals whispered in whispers. The leader who originally watched it took a while and left. It was too boring to understand!These experts are left.
"Old Chen, it's okay, your undergraduates in Lanshi are so awesome. It's only a few years after graduation, so you're so skilled."
"Nonsense, what do you think."
"Shameless stuff, it's like your student." The other party can't talk, the professor who talks is a little angry, and scornful.
In fact, his tone is a bit look down on Lanshi, after all, he is a bit more southward.
"It's okay, just look at 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.
"Ok!"
The tender pig skin is probably still premature pig skin. It has been soaked in various medicines and is a little swollen. It is curled together as if the skin of fruit has been soaked in water.
"Alice pliers, four. Director, come and help me to open it, Lu Shuyan, slowly open it, don't use too much force." The pig skin with a vascular pedicle is too thin, and said too much force. Uncertainty will be broken.
When he opened the pigskin, Professor Li Housen's heart almost popped out of his throat.If you can't do this step well, you don't need to expect anything, and you won't be able to do the following.
The three of them were equally powerful, "Come, slowly down, come, slowly, 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.
"Fix the ophthalmic forceps, fast." The position is very good, completely covering the face of the wounded.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 separated from the physiological fluid, if it cannot quickly connect to the circulatory system, the thing will become necrotic.
Start the operation under the microscope, first establish the channel.Allogeneic transplantation cannot damage the inner layer of human blood vessels, because various signal factors will be exposed after injury, and once the human body is exposed, it will become a battlefield.
Under the microscope, the hemostatic forceps and the hemostatic forceps are facing each other, pinch the blood vessels of the human body, and pull off the blood vessel outer mold.The blood vessels of the human body can be roughly divided into three layers. The inner membrane contains 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 dullest, and the outer layer becomes more sensitive. The inner layer cannot be destroyed. Once it is destroyed, it can release various factors and call in various soldiers. The outer layer can be destroyed. Pull off the outer layer of the interface. .
Then put this skinless blood vessel head into the blood vessel of the piglet skin. The muscle layer of the human blood vessel is attached to the inner layer of the blood vessel of the piglet. The muscle layer does not matter, as long as you wear clothes.
Then there is suturing. The difficulty comes. At this time, suturing has to penetrate the blood vessels of the piglet through the vascular muscle layer of the human body, but not through the inner layer. It is really a dojo in a snail shell. Who dares to practice a thousand times without having muscle memory?Who can?.
Sew one by one, move forward a little bit.Zhang Fan breathed slowly, and countless exercises in the system had already given him a feeling of breaking through the blood vessels. This was exchanged with countless hypoglycemia symptoms, which was exchanged for various mysterious days. Come.
Not to mention that the surgeon who performed the operation did not dare to show up, not even Professor Li Hosen and Professor Yan Dehua who were watching by the side of the operation.
Although they couldn't see the specific operation, Professor Li Hoousen's face was flushed looking at Zhang Fan's super stable hands, and he kept shouting in his heart: "That's it, that's it."
"It's too stable!" The experts in the conference room looked at each other poisonously, and they saw it when they started stitching.
"Yeah, it's too stable. I just don't know how long it will 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 inside the other, the front side is sutured first, and then the other side is turned over 180 degrees.
Zhang Fan lifted the adventitia of the blood vessel, and on a blood vessel with a diameter of not more than 1mm, if the fracture was calculated according to this clock face, it should be sutured at 12 o'clock and then sutured at the opposite 6 o'clock.
Stitch the third stitch at 2 o'clock, stitch the fourth stitch at 4 o'clock, turn it over, stitch the fifth stitch at 8 o'clock, and sew the last stitch at 10 o'clock.Every suture has to go through the blood vessel twice. It's really difficult. It's just like smoking a cigarette in a gas station. It can explode with one breath and one breath.
Every time you sew, the bean's sweat will come out. It is really difficult to control the strength and the continuous output. The left and right hands must cooperate very cleverly. It is really difficult to be as crisp as the inner membrane of a raw egg.After sewing once, Zhang Fan had to stop and wipe the sweat once to restore the energy of the muscles.
"Glucose!" Zhang Fan felt a little dizzy. It took more than three hours for the facial skin to reach the jaw.After greedily taking a sip of high-concentration glucose, continue.
Small blood vessels, small nerves, and microscopic lymphatic vessels are more difficult to deal with, and more complicated than the other.If the blood vessels are not sewn, the skin will not live, the nerves will not be sewn for a little longer, the skin will shrink, and the lymph will be endlessly swollen in the later stage.
What else can I do, liver.The people inside and outside the operating room were all worried.The more hopeful, the more worried.The better Zhang Fan performed, the more worried everyone was.
Repair and rebuild the eye sockets, follow the texture and paste the nasal cavity, repair the lips, step by step.The bloody face gradually became acceptable.
"Open the hemostatic forceps!" In an instant, blood entered the foreign body's skin through the repaired pipe, and the pale pig skin became bloody.
"How is it?" Professor Li Housen asked quietly with a dry throat. The heart that was held together was very uncomfortable.
"It should be possible." Zhang Fan looked at his masterpiece and said slowly. Although he will not see a brilliant smile or rich expression in the future.However, he can walk in the sun and face the world happily.
