Chapter 298： Constant failure (2/4)

"It's really simple and rude." Su Yun also saw the squirting of the needle during the interval: "For a world-renowned professor, you can't twirling?"

"Oh." Zheng Ren interrupted Su Yun's words with a boring voice, and then picked up the phone and called the Xie Yi and Chu Yuran to arrange for the surgery.

After the fight, Zheng Ren called Feng Xuhui again, confirming that there was a full set of TIPS surgical equipment, and urged it again and sent it as soon as possible.

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

After all the calls, Zheng Ren and Su Yun have come to the operating room.

Change clothes, silence.

The patient has not been sent, Zheng Ren is not particularly anxious, see Su Yun replaced the isolation suit, he took out the cigarette box, said: "You go to help prepare, I smoke."

It is common to smoke cigarettes and calm your emotions before surgery. Su Yun gave a cry and went to the operating room.

Zheng Ren went to 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 value into the training time.

The operating room of the system was raised and the experimental body was ready.

Zheng Ren began training surgery.

Jugular vein puncture, no difficulty.

It is also difficult for the guide wire to enter the heart through the jugular vein and then to the hepatic vein.

This vein is like the capillary artery of benign prostatic hyperplasia, like the side-by-side eight-lane road and the rugged road in the countryside. Don't be too spacious.

But the next step is difficult.

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

failure……

Change position,

failure……

Change position again,

failure……

Dozens of needles hit, there is no way to penetrate the hepatic vein, find the branch vein of the portal vein in the liver.

It’s hard...

It’s really hard...

It is the pearl of the crown...

After the 42nd failure, Zheng Ren stopped.

Although the training time is very valuable, but doing so blindly, the effect is limited.

The portal is wide, even in the case of branch veins.

However, it is not enough to accurately find the location of the portal vein in the hepatic vein and ensure the successful puncture.

But... what skills do you need?

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

Dozens of needles fail to puncture and do not cause sudden death.

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

But if there is more failure... I am afraid that the liver will be worn by the needle...

The upper limit of failure that can be tolerated is 20-30 times.

In other words, the impact has a chance of hitting up to 30 times. No wonder the average operating time in the world is 4 hours and 23 minutes. Everyone is taking a chance.

If you are facing the patient, not the experimental body of the system operating room, Zheng Ren can not do this.

Or take a look at the information first, as it is a sharpening.

After all, sharpening the knife does not mistake the woodworker.

Zheng Ren left the system operating room and began to look through various materials in his mind.

The documents and materials that I have seen in the library before are now clearly and unpredictably appearing with my thoughts, without any effort.

The level of intervention at the master level also played a significant role in the silent reading of the literature. Many places that Zheng Ren could not understand before, now it seems very simple and clear.

Coupled with his extensive experience in liver anatomy, Zheng Ren quickly gained a lot of experience in TIPS surgery.

And these experiences are all failed by the predecessors, and they are created with one life.

Despite this, the system operating room has several drawbacks.

That is the time is tight, every minute and every second is to do the task. When the time is up, the system will definitely kick out Zheng Ren, and there is no room for negotiation.

Then there is only Zheng Ren himself, there is no mature mentor to teach and impart experience.

Everything can only rely on Zheng Ren's reference and explore it on its own. A lot of sensory experience can't be written in the literature, Zheng Ren knows.

The fastest speed to integrate the whole process of TIPS surgery with liver anatomy, the various experiences mentioned in the literature, both success and failure, Zheng Ren has recorded.

Subsequently, Zheng Ren changed an experimental body.

After dozens of failures, the previous experimental body has no way to use it.

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

failure……

failure……

failure……

Fuck!

Zheng Ren almost went crazy.

This time, he already has a certain degree of certainty in his heart. After all, TIPS surgery was initially carried out in conjunction with the two departments.

And Zheng Ren itself, the level of intervention at the master level, the level of general surgery at the master level, and the dual specialization are rare in the world.

Among them, especially the experience of liver anatomy, equivalent to hundreds of thousands of general teachers were squandered by Zheng Ren alone. In the real world, this is simply not possible.

But... this will not work, to what extent is TIPS surgery difficult? !

impossible!

Zheng Ren’s first thought was to deny that he could not.

If you can't do it, no one can estimate it.

It should be time-critical and I am going the wrong way.

What is wrong with that?

Zheng Ren waved and the operating room disappeared.

The operation time is limited and he can't waste it. But outside time...more limited, the patient was immediately taken to the operating table.

He sat quietly beside the small pond, watching the lifelike little fox fall into meditation, recalling every step of his surgery, looking for the possibility of improvement.

After a few minutes of contemplation, a sudden pain came.

Zheng Ren quickly left the system operating room, throwing away the cigarette butts burning in his hands.

He thought about it and gave Su Yun a phone call to let him contact Feng Xuhui, let Su Yun accept consumables, and don't bother himself. When is the patient sent, ready to start surgery, and when to call yourself.

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

Putting down the phone, Zheng Renzhen cherished the moment in front of him and entered the system space again.

What is wrong with that?

Zheng Ren quickly swallowed the surgery process There is only one difficulty, that is, the puncture needle is affected by blood flow in the portal vein, and interferes with his own judgment.

So what about starting with imaging?

CT? Nuclear magnetic?

Zheng Ren suddenly remembered the passive ability after the completion of the second phase of the [First Debut] - fusion.

Maybe this is the case?

He is going to give it a try.

The experimental body prepared by the system is very intimate, and all kinds of examinations are available.

Zheng Ren entered the surgery training room. This time, he did not have an urgent operation, but began to read the patient's CT and nuclear magnetic enhancement films.

Surgical training time passed by, but Zheng Ren did not regret it.

Sharpening the knife does not mistake the woodworker.

A few hours passed, and Zheng Ren’s eyes flashed a glimpse of light.
