"Su Yun, record this location. Zheng Ren pointed to a branch of the superior bladder artery and said to Su Yun, who had been standing behind him.

Su Yun held a pen and paper in his hand and recorded the location that Zheng Ren said.

The recorded text is not in Chinese or English, but in some special symbols that only he can understand.

Although it is recorded in the simplest symbols, a piece of A4 paper is also full of writing, and it looks like it is about to change to the next page.

And on a similar piece of paper, three sheets have already been written.

"How's it going?" Su Yun noticed the slight change in Zheng Ren's expression, and it seemed that there was a breakthrough, so he asked.

"I should be able to give it a try. If there is a finer micro guidewire, the effect will be very good, and under the existing conditions, we can try the interventional guidewire of neurology as mentioned before to open the subtle branch artery. ”

In interventional neurology procedures, the diameter of the microguidewire is the shortest, thinner, and more difficult to manipulate.

Even so, it does not meet the needs of interventional surgery for the prostate.

But under the existing conditions, this is the only way to do it.

After the two exchanged a few words, they were busy again.

Zheng Ren was still rebuilding, and from time to time told Su Yun to record a certain location. The recorded anatomical locations are scattered and do not have a certain regularity at all.

Su Yun stood behind Zheng Ren very seriously, and for ten hours, he was almost motionless. At this moment, Su Yun is the most perfect assistant.

At 4:12 a.m., after constructing the capillary network of the last blood vessel branch, Zheng Ren let out a long breath, and a long-lost smile appeared on his face.

"It's finished?"

"Almost, the next step is to test the technical level of the two of us. Zheng Ren pointed to the screen and said, "The branch arteries branched out from the six large blood vessels evolved into a capillary network to supply blood to the prostate. ”

"Are you sure?" Su Yun didn't think that Zheng Ren could do it, those thin and dense capillary networks were difficult to achieve with the current level of technology to intervene in overselection and embolization.

"Not at all. Zheng Ren told the truth.

The 3D reconstruction of 64-slice CT is only the first step. Like a wartime military map, let yourself know what you need to do next.

The rest...... Jung In counted the time and experience points of the surgical training in the inventory.

Splurge? It seems like it's time to splurge.

There seems to be a golden treasure chest as well, can you have good luck? As soon as this thought came to mind, it was thrown out of the clouds by Zheng Ren.

Don't think about such a thing as luck.

A few hours earlier, Zheng Ren had made a preliminary surgical plan after making the capillary network constructed by the first branch artery.

Because the blood vessels are too thin, it is necessary to perform an operation similar to Lin Jiaojiao's opening of the ophthalmic artery - using a micro guide wire to pass through a blood vessel with a diameter thinner than the guide wire, and it cannot exceed the compliance of the blood vessel, resulting in secondary bleeding caused by the surgical operation.

This kind of unconventional operation is rarely done. Even if they do, most of them end in failure. If Zheng Ren hadn't succeeded once when he opened Lin Jiaojiao's ophthalmic artery, I'm afraid that Su Yun and Director Kong would have scoffed at this surgical plan.

But even if there is a successful precedent, the two are not optimistic about this surgical plan.

It is very difficult to do this, but after discussion, the weakness of the domestic micro guidewire has turned into an advantage in a specific period.

The domestic micro guidewire is relatively hard, and the difficulty coefficient of operation is one level higher than that of the imported guidewire.

A slightly stiffer guidewire is a disadvantage during normal surgery. But before Jung In's "opening technique", the disadvantage turned into an advantage. With a little care, the likelihood of success in theory increases dramatically.

Therefore, Director Kong went to inform Feng Xuhui to use their guidewire.

This kind of thing, and Feng Xuhui said, it is not good to say whether he can keep the fruits of his victory.

Director Kong also has a heart, and when he saw that Feng Xuhui was following Zheng Ren in the past few days, he made a down-to-earth favor and asked Feng Xuhui to inform the senior management of Changfeng Minimally Invasive to talk to him.

Zheng Ren didn't know these things, and he didn't want to know.

His whole mind was immersed in the idea of the operation, and he couldn't extricate himself.

If the operation is not done well, no matter how much else you get, it will be useless, Zheng Ren understands this truth.

"Take a break. Zheng Ren woke up Director Kong, who was already asleep in the chair, and whispered.

"Back to the interventional department, I'll sleep for a while. If you still have the energy, look at the surgery performed by Professor Rudolf Wagner of the University of Heidelberg and see if there is anything to learn from. Director Kong said.

Zheng Ren nodded.

For a body less than thirty years old, staying up all night is nothing. Especially for clinicians and emergency department inpatients, staying up late is a necessary skill. And the old directors, as they get older, the skill tree that stays up late is also withering.

This is an inevitable trend of human physiology.

A few people walked out of the CT room, Feng Xuhui did not wait outside the door this time, it is estimated that he went to the airport to pick up his big boss.

When he came to the demonstration classroom of the interventional department, Director Kong turned on the video, and he was already extremely sleepy, and went to his office to squint for a while.

I can't say anything about it today, but I can rest for a while.

Zheng Ren and Su Yun watched the recording of Professor Rudolf Wagner's surgery.

Just like the feeling of other professors watching the recording last night, the skillful technique and the micro-guidewire and microcatheter at hand jointly constructed a perfect operation.

Su Yun sighed in his heart, a little helpless.

In his opinion, Professor Rudolf Wagner's operation is slightly stronger than Zheng Ren's, and with the micro guide wire and micro catheter at hand, it can be said that this operation is beyond Zheng Ren's current operation.

It's not that hard to surpass.

Jung in is not yet thirty years old, and he will have five years at most...... No, maybe three years is enough, and Zheng Ren's level will definitely surpass Professor Rudolf Wagner.

But to say this now means that this scientific research has failed.

Success or failure, Su Yun doesn't care about the consequences. It's just that the flame of victory in his heart is burning, and he is not in a good mood if he does not cross the mountain of Professor Rudolf Wagner.

The operation was completed smoothly, and after removing the anterior and posterior perioperative operations, Professor Rudolf Wagner completed the entire process of prostate embolization in a little more than an hour.

Almost perfect.

"Boss, what do you think?" Su Yun caught a glimpse of Zheng Ren watching the video recording intently, and resumed his previous harsh way of speaking, asking with a playful voice.

"The surgery was rough. Zheng Rendao.

"......" Su Yun didn't expect Zheng Ren to answer like this, and for a moment, he was stunned, looking at Zheng Ren like a monster.

This guy, is there still a bit of pressure in his heart?
