Zhang Fan looked at the severed ends of the two large intestines, which were like a chicken that had been hit by a lead ball and was bleeding from a tube to a flat object, and sighed deeply. This thing is too difficult to say and easy to say.
Suturing is relatively difficult. In the past, there were three difficulties.
The first difficulty is arterial suturing. In the early years, arterial suturing was more difficult. This task is short in time and requires high requirements. People who failed to sew three times died. Therefore, the requirements for doctors are relatively high.
The second difficulty is suturing nerves. In the past, the equipment was not good, so the difficulty of suturing was much lower than that of arteries. After all, nerves don’t bleed!
But it is different after suturing. You can see whether the blood vessels are leaking or not.
But the nerves are different. You have to wait for several months to recover before you can see them. Often the effects are gone, and they can grow into neuromas. The patient twitches in pain, just like Nicholas Zhao Si’s face. Same as pumping.
The third difficulty is suturing the gastrointestinal tract.
Now another facial stitch is added. In the past, facial sutures and other tasks could be left to apprentices to practice. Now it’s no longer possible. If the stitches can’t be stitched properly, the patient will have to fight the doctor with a knife.
Of course, this also reflects the progress of the country, otherwise the people would not have enough to eat, and who would worry about whether there are scars on their faces.
With the development of surgical equipment, especially the improvement of microscopic equipment, neurovascular suturing is no longer as difficult as before.
There is no need for doctors to grab a dog and break its leg, and then try to figure out how to sew it up. The yellow dogs on the street ran like crazy when they saw the man in the white coat.
Gastrointestinal suturing has not made much progress from thirty years ago to now.
Because the human body is a weird thing. For example, in the case of cancer, there is a saying that the outcome of inflammation is either cure or cancer.
And there is another type of cancer, which is metaplasia.
This thing, how to define it, is a kind of mature cell that wants to become another kind of mature cell.
And this change often occurs at the junction of two organs. To put it simply, it is like a man who has been raised as a girl since he was a child. When he grows up, he feels that he wants to change his shape, and then he undergoes surgery.
To be honest, this thing has everything it needs when it transforms. Guan Guan turns into a hole, but its life is consumed and its body is hollowed out. He was young and died early.
The same goes for cells, especially in organs and organ junctions. It's not just people who want to be another gender.
Same goes for cells.
But this kind of change is often determined by innate genes. If you want to change, you are going against the entire organism. You are rebelling.
Can your body organs let you go?
All kinds of immune cells come directly with guns and cannons. This is inflammation. As soon as I started fighting, I felt all kinds of aches and pains.
This kind of inflammation starts to become quite frequent when people are almost thirty years old. From time to time, ulcers or something like that appear inexplicably, such as oral ulcers.
Especially in certain age groups such as thirty-five, forty-nine, seventy-four, etc., outbreaks are particularly frequent.
According to the old folk saying, at seventy-four or eighty-five, the King of Hell will not ask you to go. In fact, the decline of human body functions does not decline linearly, but in a leap-forward manner. From thirty to thirty-five, the rate of decline is slightly faster than in the twenties.
But not much faster.
But when it reached thirty-five, it dropped off a cliff, then slowly dropped again, and when it reached seventy-five, it dropped off a cliff again. For example, when I was in my early thirties, I could have sex seven times a night. When I was thirty-five, I was chased all over the place by my young wife holding my pants.
Before the age of seventy, you can stand up to pee your shoes, but after seventy-five, it is often difficult to take it out. If you don't wet your crotch, you are already a hero!
This is a sign of significant decline in function.
A significant decline in human body functions often leads to a decline in the immune system.
Then the immune cells suddenly cannot defeat these rebels who want to rebel and become other cells.
At this time, the rebellious cells undergo metaplasia and transform into other cells.
As a result, the transformation failed and turned into cancer.
For example, portal cancer at the junction of the esophagus and stomach mostly occurs in people aged thirty-five.
For example, the connection between the cervix and the guide, cervical cancer.
Duodenal gastric cancer at the junction of the stomach and intestinal tract has a high incidence rate in people aged thirty-five.
There are also bone cancers caused by this kind of metaplasia where hard bone and cartilage are connected.
Therefore, most cancers, especially malignant cancers, often occur at the connections between organs.
If a person wants to change his gender, it is like a cell trying to metamorphose. The outcome will not be good.
Just like the taste of large intestine is obviously different from that of small intestine, meat and meat are different. It is too difficult to transform.
The same is true for intestinal suturing. If the suturing is not done well, the cells connecting the large intestine and the small intestine will be restless, and if the suturing technique is not good, the cancer will not escape.
Therefore, Zhang Fan had to take too many steps to sew up the intestines.
It starts with sanding.
That's right, it's just polishing, just like repairing a broken inner tube of a bicycle wheel. You need to polish the broken area first to roughen the edges of the rubber surface.
Only then can the stick be firmly attached.
The suturing between the intestines is actually similar.
Start by destroying the capillaries at both ends of the intestine, not the large blood vessels. The large blood vessels were damaged and the intestines were directly necrotic.
After the capillaries are destroyed, their tissue structure is destroyed.
They are then sutured, and as they heal, they consult with each other and finally reach an agreement to form unified cells and blood vessels.
If the microstructure is not destroyed.
After suturing, the small intestine grows into the small intestine, and the large intestine grows into the large intestine. Finally, two different cells appeared in the same place, and without even thinking about it, over time, this thing turned into metaplastic cancer.
Moreover, it is catalytic. Just like when you have an ulcer in your mouth, the doctor tells you not to smoke or drink alcohol.
The patient agreed in person and ignored her, saying that he should drink and smoke when he should. He also said that my grandfather smoked and drank for ninety-nine years.
Then, under the stimulation of tobacco and alcohol, the festering cells and blood vessels had no intention of metamorphosis, but they were suddenly seduced and transformed, and those who had no cows became cows and cows.
And suturing is another catalyst.
Therefore, this kind of suturing of the small intestine and large intestine requires considerable attention.
Like a craftsman, Zhang Fan rubbed between the two intestines for several minutes.
Zhao Yanfang almost went crazy.
Because Zhang Fan rubbed it a little too much.
Although she is not married, she has been in love.
Seeing Zhang Fan's technique, she seemed to remember something...
In fact, Zhang Fan was simulating it in the system in his mind.
"No, it's timed out!"
"No, my intestines are rotten!"
After trying again and again, Zhang Fan finally opened his eyes.
If it weren't for his shining eyes, Coach Zhao would really have thought that Zhang Fan had become a sage.
"Can you ensure that intestinal necrosis will not occur within three minutes of freezing, and can you ensure that the intestine can be extended?"
Zhang Fan stared at Zhao Yanfang, how could he be a sage? He was obviously looking like a tiger descending from the mountain, wanting to eat people.
Coach Zhao is usually relatively strong against Zhang Fan. Moreover, Zhang Fan knew that his scientific research was not very good, so he felt a bit shy about Coach Zhao.
But now, he has piercing big eyes and a strong male lion-like perseverance. It actually made Mr. Zhao stunned.
"Okay! But you have to be quick."
"Don't worry, I'm fast enough. Let's start!" Zhang Fan has successfully operated a suture method in the system.
Medical treatment actually has templates for common diseases. Every year, we compile medical guides for various departments compiled by major experts.
In fact, it means telling doctors what the latest and best treatments are for common diseases. You don’t have to figure it out on your own, I’ve told you all.
But at the high end, let alone guidelines, even if you bring in doctors to compile guidelines, you may not be able to have a unified treatment method.
Therefore, the more high-end a doctor is, the more he pays attention to individual treatment differentiation.
As soon as Zhang Fan spoke, Old Zhao and Zhao Jingjin grabbed Zhang Fan's sterile-gloved hand.
"You have to think twice. The time is too short and the difficulty is too high. Once you start this kind of cryo-suturing, there is no way back. If necrosis occurs, it will be troublesome."
"Yes, I understand!" Zhang Fan looked at Lao Zhao and nodded.
There was obvious disapproval on Lao Zhao's face.
Zhang Fan added, "Don't worry, I'm sure, you have to help me. Dr. Zhao is still a little lacking."
"Okay! Go all out!" Now that Zhang Fan has decided, even if Lao Zhao disagrees, he will still help.
This is the surgical team.
Zhao Yanfang wanted to speak, but didn't!
Heaven's way is so easy to reincarnate, who will God spare!
She used to despise Zhang Fan, but now she is despised by Zhang Fan, and she has no way to defend herself!
The patrol nurse took the frozen ice cubes and heated warm water to the operating table and handed them over to the instrument nurse without contact, just like handing over a bomb.
The freezing begins.
When the ice cube is placed in the small intestine, the warm water is close to the large intestine.
Zhang Fan and Zhao Jingjin were like Demacia hiding in the grass, waiting for the other party to hand over their skills and shout Hallelujah when they came out of the grass.
The frozen small intestine looks like a snake shedding its skin.
The outermost layer slowly shrinks, and the inner three layers slowly extend. If you fast forward this thing, it really looks like a engorged chicken, no exaggeration at all.
Under the application of warm water, the large intestine, which was originally cut off like a pocket, even expanded.
Even the tissue that was originally a little stiff due to lack of blood has become warmer, and its color has become pale and soft.
"start!"
Zhang Fan quickly polished the broken ends of the large and small intestines with gauze.
Instantly, the two broken ends looked like they had been rubbed red...
I'm starting to feel a little congested and edematous.
Microtissue destruction completed!
This is the effect you want.
The stitching begins!
Zhang Fan holds a needle in one hand and toothed tweezers in the other. The instrument nurse's tray is already filled with needle holders hung with sutures.
It is impossible to keep up with this kind of stitching, which is now worn and provided.
Zhang Fan's suturing was so fast that it felt like he was directly inserting the needle into the intestines.
And Lao Zhao, with his hands tied in knots, danced as if Jiumozhi was playing with the Six Meridians Divine Sword.
Zhao Zipeng took the scissors and cut the threads with a click.
At this time, no one can make mistakes.
The sutures of the intestines are sutured layer by layer from the inside out.
Once a mistake is made, the chance to sew again is often gone.
The four people on the operating table didn't even dare to breathe.
