Chapter 381 The First Actual Use Of Artificial Cornea!
Tang Rongrong: "My superiors have asked me to find a volunteer who needs cornea replacement to try your artificial cornea. The project will be settled only if it succeeds."
Song He replied, "Okay, what day? I'll let the team prepare."
Tang Rongrong: "The sooner the better, what do you mean?"
"I need a fresh butt film. It doesn't need to be too thick, just half a centimeter." Song He thought about it and replied, "After the butt film is delivered, the artificial cornea can be made in 4 hours at the fastest. It needs to be transplanted immediately after it is done. The sooner the better! If it's convenient, we can do it today and tomorrow!"
Tang Rongrong was silent for a moment, probably consulting the surgeon.
After a while, an electronic file was delivered.
[Patiman, female, 37 years old, blinded by optic nerve atrophy in the right eye, two glaucoma surgeries in the left eye, recurrent blurred vision in the left eye 3 years ago, diagnosed with corneal endothelial decompensation in the left eye, recommended corneal transplant surgery]
Attached is a photo of the patient. She is a pretty beauty from the Western Region, but unfortunately she is blind in both eyes. The eyeball of her right eye is scrapped, and the cornea of her left eye is scrapped. The beauty's face is vaguely sad, and there is a knot between her brows that cannot be removed.
Tang Rongrong: "She is a volunteer. The superior's plan is to arrange a medical plane to fly her over. The surgeon team is on the plane and will cut the skin and send it to your laboratory immediately. After you have done the cornea, we will send someone to send it back immediately. The operation on the plane will take no more than ten minutes on the road.”
Song He thought for a while, "It's fast enough, but won't flying affect the intraocular pressure?"
Tang Rongrong: "Don't worry, the medical plane will stay in Ruoqiang for two days, waiting for her to remove the gauze before returning. If everything goes well, the gauze will be removed one day after the operation, and she will slowly recover with eye drops for a month, and her vision will gradually recover. "
Song He: "Okay, I'll send it to you. How long will it take to arrive?"
Tang Rongrong: "The plane is still being coordinated. I'll let you know when it sets off."
…
At one o'clock in the afternoon, a small white passenger plane landed at the Ruoqiang base airport with a crash.
The red cross painting on the tail of the plane is extremely rare. This is a rare medical plane. It flies around every day to transport all kinds of medical supplies with extremely short lifespan, such as fresh organs for transplantation, blood banks for emergency support, etc.
After the passenger plane taxied to a stop, an ambulance, which had been waiting for a long time, rushed over and waited silently under the plane.
At half past one, the plane door opened, and medical staff hurriedly got off the plane with a white biological sample box in their arms and handed it over to the medical staff standing next to the ambulance.
The doctors and nurses got into the car with the box in their hands. The ambulance rang the bell and left quickly, crossing the apron and speeding towards the Ruoqiang base in the distance!
In just five minutes, the ambulance rushed to the gate of Military Industry Town. Countless passers-by stopped curiously and talked about it along the way.
The sentry in Military Industry Town had already received the notice and raised the pole to let the ambulance pass in advance. They saluted and watched the ambulance pass by, secretly guessing what was in the car. The sentry thought about countless possibilities for a moment, but he did not guess that it was a small piece of buttocks.
After several consecutive left and right turns, the ambulance stopped at the entrance of a laboratory, arriving!
A few people in white coats were shivering from the cold at the door. When they saw the ambulance appearing, they rushed to greet it with shouts!
In the laboratory, Song He sat on the table with his arms folded, looking serious, like a general waiting for the battle to begin.
He was lowering his head in deep thought when he suddenly heard the sound of an ambulance coming from the door. He immediately raised his head and his eyes flashed sharply!
There are several experimental stations around, and dozens of people in white coats are waiting in full formation, and the atmosphere is tense!
There is no psychological burden in conducting experiments on monkeys. If something goes wrong, it will just change to another monkey. The fate of the experimental monkey is to devote itself to science and leave the data for history.
But the situation is different today. It is made with human skin, and there is absolutely no room for failure! Failure to do so means that the patient will suffer an additional penalty!
At the door, two men in white coats ran in carrying boxes, "Here they come!"
Song He clapped his hands and shouted, "Work! Keep your spirits up and don't make mistakes! Each team will make three corneas at the same time! Make sure the thickness of each layer is controlled, and the error with the original cornea of the human eye cannot exceed 5%!"
With one order, everyone moved!
The entire team is like a sophisticated machine, with gears, chains, and connecting rods. The box lifted in is like an inserted key, starting the machine instantly and making all parts work closely!
The work of each group is consistent with the research and development. Whoever should do the stromal layer will do the stromal layer, and whoever should do the front and back elastic layers will do the front and rear elastic layers. In fact, it is just a monkey's butt replaced by a human's butt, and the research and development process is repeated again.
Song He walked back and forth nervously, observing the progress of each group.
He had never been so nervous since he started doing scientific research, as if the Pattiman on the medical plane was his daughter.
"The front and back elastic layers are completed!" Fan Tao was the first to announce the good news.
"The matrix layer is completed!" Lou Jinghui announced the good news.
Song He returned to the experimental table and worked on his own part, making two types of cells: basal cells and flat cells.
Two different corneal differentiation fluids have been prepared long ago, and after a methodical operation, the basal cells were successfully completed!
A total of four pieces of flat cells were made, but one piece was inexplicably useless, making Song He sweat all over. Fortunately, the remaining three pieces were all successful, and there was no danger!
Ji Tian and his team quickly delivered the newly prepared wing cells and gathered all the cells in the epithelial cell layer!
After changing the solution, desmosomes quickly formed the plasma membrane, and the three types of cells were tightly combined!
"The epithelial cell layer is complete!" Song He and Ji Tianhe announced the good news at the same time.
Almost at the same time, Lu Chengen said, "Endothelial layer, completed!"
Morale boosted!
At this point, the five layers of the cornea are completed!
Each group put the completed corneal layers on an experimental table. Song He performed the surgery himself, poured in splicing fluid, and carefully began polishing!
Now comes the hardest part! !
Previously, when the monkey cornea was polished to a fixed thickness, a black technology blueprint would pop up.
But at this moment, Song He could only rely on machine data and his own touch to polish the cornea into the target shape!
The whole place was tense, with dozens of pairs of eyes staring at the boss, praying wildly in their hearts, asking for the blessings of the gods and Buddhas in the sky.
"The first one is broken!" Song He said suddenly.
There was silence all around, and there was faint sweat on the foreheads of dozens of people. It had been four hours since the box was brought in, and a total of three corneas had been made. One of them was broken now, and there were two chances left!
There was a long silence, only the humming sound of machines running.
"The second one... is defective!" Song He sweated on his forehead, "It's barely usable!"
Song He released the machine and asked team members to remove the second cornea.
Fan Tao, with quick eyes and quick hands, took a handkerchief and wiped the boss's sweat, carefully wiped off the fine sweat on his forehead, and squeezed his shoulders.
"Don't be nervous, boss! You can definitely do it! You are the best!" Fan Tao encouraged in a stereotypical line.
Song He nodded, took a deep breath, and leaned on the instrument again.
It was the last chance. This time, everyone simply didn't dare to breathe, and they all suppressed their breathing to the level of breathlessness.
However, Song He's operation took an extra long time this time. Everyone was collectively deprived of oxygen, like a breath-holding competition, and their faces were slightly abnormal, but everyone still persisted.
Many people don’t even realize they’re holding their breath, they’re just too nervous!
Finally, when some team members with small lung capacity were about to suffocate to death, Song He suddenly stood up from the machine!
