"It's really simple and crude. During the interval, Su Yun also saw the stitches spraying: "For world-renowned professors, you can't be tactful?"

"Huh. Zheng Ren interrupted Su Yun's words in a boring hehe sound, and then picked up the phone and called Xie Yiren and Chu Yanran to arrange the preoperative preparations for the operation.

After the fight, Zheng Ren called Feng Xuhui again to confirm that there was a set of tips surgical equipment, and urged him again to send 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 come to the door of the operating room.

Change of clothes, silence.

The patient hadn't been sent over yet, and Zheng Ren was not particularly anxious, seeing that Su Yun had finished changing into an isolation gown, he took out a cigarette case and said, "You go and help prepare, I'll smoke a cigarette." ”

It is common to smoke a cigarette before surgery to calm your mood. Su Yun answered 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, Jung in exchanged all the bonus time and experience points for surgical training time.

The operating room of the system rises from the ground, and the test subjects are ready.

Jung in began training for surgery.

Jugular venous puncture is not difficult.

The guidewire passes through the jugular vein to the heart and then to the hepatic vein.

Compared to the capillaries of prostatic hyperplasia, this vein is not too wide like eight lanes side by side and a rugged dirt road in the countryside.

But then came the difficulty.

The puncture needle entered, Zheng Ren estimated the length and distance, and then began the puncture.

Fail......

change position,

Fail......

Changing positions again,

Fail......

Dozens of injections were given, but there was no way to penetrate the hepatic vein and find the branch vein where the portal vein was in the liver.

It's so hard......

It's really hard......

It deserves to be the jewel in the crown......

After the forty-second defeat, Jung in stopped.

Although surgical training time is precious, the effect of doing it blindly is limited.

The portal vein is relatively wide, even if it is a branch vein.

However, in order to accurately find the location of the portal vein in the hepatic vein and ensure the success of the puncture, luck alone is not enough.

But...... What skills do you need?

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

Failure of puncture with dozens of stitches 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 path can quickly be compressed and stopped by the pressure generated by the solid organ.

But if there are more failures...... I'm afraid that the liver will be pierced by the puncture needle......

The upper limit of the approximate tolerable number of failures is 20-0.

That is, the impact has a maximum of 0 chances of luck. It's no wonder that the average surgery time in the world is 4 hours and 2 minutes, and everyone is trying their luck.

If he was facing a patient, not an experimental subject in the operating room of the system, Zheng Ren would not dare to fool around like this.

Let's take a look at the information first, as a sharpening knife.

After all, sharpening a knife is not a mistake for a woodcutter?

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

The documents and materials that I used to read in the library now appear with my thoughts with great clarity and effortlessness.

The level of intervention at the grandmaster level also played a great role in the silent reading of the literature. There are many things that Zheng Ren couldn't understand before, but now they seem to be 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 forged by predecessors with failures again and again, and with lives one by one.

That said, there are several drawbacks to the system operating room.

That is, time is pressing, every minute and every second is obtained by doing tasks, and when the time comes, the system will definitely kick Zheng Ren out, and there is no room for negotiation.

And then there is the fact that there is only Zheng Ren himself here, and there is no mature mentor to teach and impart experience.

Everything can only rely on Zheng Ren's references and explore on his own. A lot of sensory experiences can't be written into the literature, and Zheng Ren knows this.

The process of TIPS surgery and liver anatomy were integrated as quickly as possible, and Zheng Ren wrote down all the experiences mentioned in the literature, whether they were successful or unsuccessful.

Subsequently, Zheng Ren changed to an experimental subject.

After dozens of failures, the last test subject was no longer usable.

Jugular venipuncture, into the hepatic vein, begins needle puncture.

Fail......

Fail......

Fail......

Exercise!

Jung in almost went crazy.

Originally, this time, he already had a certain degree of certainty in his heart. After all, TIPS surgery was originally a joint effort between the two departments of interventional surgery and general surgery.

And Zheng Ren himself, the level of grandmaster-level intervention, the master-level level of general surgery, and the double specialization, are very rare in the world.

Among them, especially the experience of liver anatomy, it is equivalent to hundreds or thousands of general teachers being squandered by Zheng Ren alone. In the real world, this simply can't happen.

But...... This can't be done, how difficult is the TIPS surgery?!

No way!

Zheng Ren's first thought was to deny that he couldn't do it.

If you can't do it, I guess no one can.

It should be that time is pressed and I am on the wrong path.

What's wrong?

Zheng Ren waved his hand, and the operating room disappeared.

The operation time was limited and he could not afford to waste it. But outside the time...... More limited, the patient is immediately sent to the operating table.

He sat quietly by the small pond, watching the lifelike little fox fall into deep thought, thinking back to every step of his operation, looking for possibilities for improvement.

After pondering for a few minutes, a sudden pain came over me.

Zheng Ren hurriedly walked out of the operating room of the system and threw away the cigarette butt that burned to his fingers in his hand.

He thought about it for a while, and called Su Yun again, asking him to contact Feng Xuhui and ask Su Yun to accept the consumables and not disturb himself. When the patient arrives, is ready to start the surgery, and when is he or she calls himself.

Su Yun was a little incomprehensible, but in the face of emergency surgery, he did not question Zheng Ren's decision.

Putting down the phone, Zheng Ren cherished every minute and second in front of him and entered the system space again.

What's wrong?

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

So what about imaging?

NMR?

Zheng Ren suddenly remembered the passive ability after completing the second stage of the mission-fusion.

Perhaps?

He was ready to give it a try.

The test subjects prepared by the system are very caring, and various examinations are available.

Zheng Ren entered the operating training room, and this time he did not rush to do the operation, but began to read the patient's T, MRI-enhanced films.

The time for surgical training passed little by little, but Zheng Ren did not hesitate.

Sharpen the knife and do not mistake the woodcutter.

A few hours passed, and a glimmer of enlightenment flashed in Jung In's eyes.
