Mu Tao stood beside Mr. Wu, as if he had ever been before.

In the operating room, Boss Zheng began to step on the line.

On the screen, the guidewire slowly moves forward and then rests on the end of the ocular artery after a few minutes.

Because the super choice should be close to the retinal capillary network as much as possible, Boss Zheng used the thinnest guidewire.

It is thinner than the guidewire for neurological interventional surgery, and is the kind of guidewire that specializes in the interventional surgery for babies.

This kind of guide wire is soft and cotton, and it is not enough to use any strength. The pleating process during the super selection process is particularly likely to cause the super selection failure.

However, seeing that the micro guidewire controlled by Boss Zheng was moving slowly, it made a mistake and did not operate again, Mu Tao felt emotion.

"Mu Tao, do you know Boss Zheng's method?" asked Mr. Wu.

"Teacher, I should have an understanding of the turbulence caused by the blood flow in the blood vessels." Mu Tao said, "Boss Zheng has a deep understanding of turbulence. I think this is because he did a particularly good job in the interventional surgery."

"Yes." Mr. Wu nodded.

Overcoming the influence of turbulence is the most profound interventional theory and technique. Mr. Wu has been undergoing interventional surgery for half his life and only vaguely realizes that the guide wire is flowing through the blood vessels, and blood flow will have a huge impact on it.

As for how to overcome it and increase the success rate of the surgery, Mr. Wu was dewy.

Boss Zheng has mastered the skills of dealing with turbulence at a young age, and Mr. Wu admires this very much.

This is a breakthrough at the technical level, but it is difficult to quantify and even more difficult to master.

The microcatheter enters, but does not reach its limit, but stops in the blood vessels and does not touch the surrounding blood vessel walls.

The imaging started, as Boss Zheng speculated, part of the retinal capillary network was blocked, which seriously affected the red blood cells carrying oxygen to provide "nutrients" to the retina.

After confirming the condition, the operation continued. Su Yun connected the syringe to the end of the catheter and began to inject normal saline with a small amount of contrast agent.

His movements are very slow, very careful and delicate.

After normal saline entered the retinal capillary network, Su Yun began to slightly increase the pressure.

The "viscous" dye macromolecules are "pushed" forward by the normal saline injected by the syringe.

Because there are gaps between the catheter and the surrounding blood vessel walls, Su Yun has been carefully controlling the intensity of his injection of normal saline, trying to avoid causing capillaries to rupture and bleeding.

This step requires great patience.

When it is time to get fast, Boss Zheng performs the surgery very quickly; when it is time to get slow, Boss Zheng is not in a hurry at all and is waiting quietly.

Time passes.

After 12 minutes, the blocked position begins to move. The macromolecules deform under pressure and are "pushed" away little by little according to the pressure of the capillary wall.

Mu Tao knew that this was the most difficult part of the surgery.

Here, we must constantly change the strength slightly so that the pressure can adapt to the elasticity of the capillaries.

Three minutes later, Su Yun stopped.

Mu Tao's heart moved and pressed the intercom. He didn't say anything, but listened to the conversation between Zheng Ren and Su Yun.

"Boss, I can't do it anymore." Su Yun rarely admits to his conscience. "The wall of the pipe is not in line with sexual feelings. If you push it down, I feel that the capillaries will be broken. The power is small and there is no effect yet."

"Oh, then I'll do it." Zheng Ren took the syringe, "It was a heart compression during liver transplantation. Your arm strain has not been cured yet."

"Lao Fan rubbed me with squirting wine for a few days, and it was much better. But it took a while for the too meticulous operation to be done. You said, how slow the surgery should be, it was an industrial injury!"

"Oh, okay, it's an industrial injury." Zheng Ren responded lightly, without saying anything.

"Slow down!" Su Yun still reminded him worriedly.

"It's okay, I know it." Zheng Ren said, "She is still young, the retinal capillaries are elastic. I can feel the changes in resistance. I will be very careful. Don't worry."

"Su Ya, you said how much trouble you have caused me." Su Yun began to nag in vain.

"Brother Yun, I'm sorry." Xu Suya said in a low voice, her voice trembling a little.

"Don't talk to the patient," Zheng Ren said, "The airflow changes during the speech lead to changes in the pressure of the capillary network."

"There are so many things." Su Yun said contemptly, "Actually, life is not as difficult as imagined. After encountering difficult things, list all the solutions, and then you find that you can't do anything and give up directly."

I don’t know if I was talking to Boss Zheng or Xu Suya.

Mu Tao was stunned when he heard this.

"Yes, Lao Mu." Su Yun asked later.

“…”

He knew that he was "eavesdropping" and turned out to be talking to him, and Mu Tao was speechless about it.

This is a criticism that I did not do well in the surgery, but I would not talk about anything else, I only talk about interventional surgery. Who can guarantee that my surgery can be better than Boss Zheng? Nonsense!

Not only Boss Zheng, he should not be able to compare with Su Yun.

Mu Tao smiled and pressed the intercom button again.

If you don't let them listen, then you won't listen.

Looking at the images on the screen, after Boss Zheng took over, the overall operation speed seemed to be no faster than when Su Yun did it.

Many blocked black dots moved slightly and could hardly be discovered.

But as time went by, 1 hour and 35 minutes later, Mu Tao called out the previous image and performed overlapping treatment.

This comparison is simple and more direct, and the black dots at many blocked points are still very obvious.

The operation is proceeding slowly.

No one spoke, Mr. Wu and Mu Tao were waiting quietly.

Boss Zheng didn't seem to be in a hurry. He was patient and felt the pressure transmitted from the syringe carefully, adjusting his strength at any time.

A surgery lasted 4 hours and 22 minutes.

The operation is countless times more difficult than destructive embolization surgery, which can be seen from time to time.

When the dark shadow finally disappeared and the entire retinal capillary network was covered with contrast agent, Mr. Wu's body "soft" a little, and then leaned on the back of the chair.

Those blood vessels covered with contrast agent, like the rhizomes of plants, transport sufficient nutrients to the retina, allowing patients to see the light again.

The operation was successful at this point. The teacher was too nervous, Mu Tao knew.

It is not difficult to see the operation, but only the retinal capillary network is opened. However, those who know it know the difficulty of this operation. If you are not careful and fail to take the operation, the patient may suffer permanent blindness.

However, this is just an eye.

"Boss Zheng, do you want to change your hands and take a break?" Mu Tao pressed the intercom and said.

"Su Yun, are you tired?"

“Not tired.”

"No need." Zheng Ren turned around, bent his eyes through the leaded glass, leaving Mu Tao with a smile.
