"It's really simple and crude." Su Yun also whispered at a glance during the break: "You can't be more gentle to the world-renowned professor?"

"Hehe." Zheng Ren interrupted Su Yun with a boring hehe voice, then picked up the phone and called Xie Yiren, and Chu Yanran arranged the preparations before the operation.

After the fight, Zheng Ren called Feng Xuhui again, confirmed that there was a complete set of TIPS surgical equipment on the side, and urged him again to deliver it as soon as possible.

Finally, Zheng Ren called Director Pan to explain the situation.

After making all the calls, Zheng Ren and Su Yun had already arrived outside the operating room door.

Change clothes and remain silent.

Before the patient was sent over, Zheng Ren was not particularly anxious. Seeing that Su Yun had changed his isolation suit, he took out the cigarette box and said, "You go and help prepare, I'll smoke a cigarette."

Smoking a cigarette before the operation calms down, which is a common thing. Su Yun responded and went to the operating room.

Zheng Ren arrived at the small smoking room, lit a purple cloud, took a deep breath, and entered the system space.

Without hesitation, Zheng Ren exchanged all the reward time and experience values ​​for surgical training time.

The system operating room rose from the ground and the experiment was prepared.

Zheng Ren began training surgery.

Jugular vein puncture is not difficult.

The guidewire is not difficult to enter the heart through the jugular vein and then to the hepatic vein.

Compared with the capillary arteries with prostate hyperplasia, this vein is like eight lanes side by side with the rugged and muddy road in the countryside, not too spacious.

But the next step is the difficulty.

When the puncture needle enters, Zheng Ren estimates the length and distance, and then starts puncture.

fail……

Change position,

fail……

Change the position again,

fail……

After dozens of injections, there is no way to penetrate the hepatic vein and find the branch vein of the portal vein in the liver.

Very difficult...

It's really hard...

It is worthy of being the jewel in the crown...

After the forty-second failure, Zheng Ren stopped.

Although the surgical training time is precious, if you continue to do it blindly, the effect will be limited.

The portal vein is relatively wide, even branch veins are very wide.

However, it is not enough to accurately find the vein branch position of the portal vein in the liver and ensure the successful puncture.

But...what else is needed?

Zheng Ren quickly searched for various documents he had read in his memory.

The failure of dozens of needles will not lead to sudden death of the patient.

The puncture needle is not thick, the liver is a solid organ, and the damage caused by the needle can be quickly pressed and stopped bleeding with the pressure generated by the solid organ.

But no matter how many failures... I am afraid the liver will be pierced by the puncture needle...

The maximum tolerated failure is about 20-30 times.

In other words, there are up to 30 chances of trying luck with puncture needles. No wonder the average operation time in the world is 4 hours and 23 minutes, and everyone is trying luck.

If you are facing a patient, not a system operating room experimental subject, Zheng Ren would not dare to do it like this.

Let’s take a look at the information first and treat it as a sharpening knife.

After all, sharpening a knife will not delay the chopping of wood?

Zheng Ren left the system operating room and began to read various information in his mind.

The documents and materials I read in the library in the past are now extremely clear and effortless.

The master-level intervention level also played a great role in silent reading of literature. Many things that Zheng Ren could not understand before now seem simple and clear.

In addition to his rich experience in liver anatomy, Zheng Ren quickly gained a lot of experience in TIPS surgery.

And these experiences were made by our predecessors with failures and lives.

Despite this, the system operating room has several disadvantages.

That is, time is urgent, every minute and every second is obtained from doing tasks. Once time comes, the system will definitely kick Zheng Ren out, without even room for negotiation.

In addition, there is only Zheng Ren himself here, and there is no mature tutor to teach and impart experience.

Everything can only be explored by Zheng Ren's references and explored by himself. Many sensory experiences cannot be written into the literature, and Zheng Ren knows this.

Zheng Ren recorded all the experiences mentioned in the literature, whether successful or failed.

Then, Zheng Ren changed to an experimental subject.

After dozens of failures, the previous experiment was no longer useful.

The jugular vein puncture enters the hepatic vein and begins puncture needle.

fail……

fail……

fail……

Hold!

Zheng Ren almost went crazy.

Originally, he had a certain degree of confidence in his heart. After all, TIPS surgery was initially organized by the two departments of intervention and general surgery.

Zheng Ren himself, the level of master's intervention, master's general surgery level, and double-choice specialization are rare in the world.

Among them, especially with liver anatomy experience, it is equivalent to hundreds or thousands of general teachers being squandered by Zheng Ren alone. In the real world, this is simply impossible.

But... this doesn't work. How difficult is TIPS surgery?!

impossible!

Zheng Ren's first idea was to deny himself.

If I can't do it, no one will do it.

It should be time is tight and I took the wrong path.

What's wrong?

Zheng Ren waved his hand and the operating room disappeared.

The operation time is limited and he cannot waste it. However, the time outside... is even more limited, so the patient will be sent to the operating table immediately.

He sat quietly by the small pond, watching the lifelike little fox fall into deep thought, recalling every step he did during the operation, looking for the possibility of improvement.

After pondering for a few minutes, a sudden sensation of pain came.

Zheng Ren hurried out of the system operating room and threw away the cigarette butts burning in his hand to his fingers.

He thought about it and called Su Yun again, asking him to contact Feng Xuhui, asking Su Yun to receive consumables and not disturb him. When will the patient be sent, prepare to start the operation, and when will he call himself?

Su Yun didn't understand, but in the face of emergency surgery, he did not question Zheng Ren's decision.

Putting down the phone, Zheng Renzhen cherishes every minute and second before her and enters the system space again.

What's wrong?

Zheng Ren quickly sorted out the operation process, and there was only one difficulty, that is, the puncture needle was affected by blood flow in the portal vein, which interfered with his own judgment.

So what about starting with imaging?

CT?Nuclear Magnetic?

Zheng Ren suddenly remembered his passive ability after completing the second phase of the mission [First Show of Thrills] - Fusion.

Maybe that's the case?

He is going to give it a try.

The experimental subjects prepared by the system are very considerate and have various examinations.

Zheng Ren entered the surgical training room and did not rush to undergo surgery this time, but began to read the patient's CT and magnetic enhancement film.

The surgical training time passed by bit by bit, but Zheng Ren was not stingy.

Sharpening a knife will not delay chopping wood.
Chapter completed!
