The rarer the blood vessels are, the thinner and more tortuous it will be, and the more difficult it will be to successfully select one-time.

Blood vessels such as hepatic arteries, uterine arteries, and renal arteries are straight and straight in front of Zheng Ren's blood vessels selected next.

The spinal cord feeding arteries are the most complex. Zheng Ren carefully calculated the dose of contrast agent. Like a miser, he used a careful analysis and calculation every time he injected the contrast agent.

I was afraid that after the contrast agent reached the maximum dose that the human body could bear, the operation would be unable to continue.

As for the amount of line that Director Pan is worried about, Zheng Ren is not worried.

The system is equipped with radiation ray energy-converting lead clothing, showing extremely powerful attributes. The longer you stand in the operating room, Zheng Ren not only does not feel tired, but instead becomes more and more energetic and the operation becomes more and more meticulous.

When he was watching Zheng Renchao select spinal cord and offering arteries, Professor Pei was stunned. As the super selection was successful, he sighed.

Director Pan was afraid that Zheng Ren had reached his physical limit, so he immediately asked: "Professor Pei, what's wrong?"

"Director Pan, your hospitalization officer is really amazing!"

"ah?"

"There is no monotonous anatomical structure of the spinal cord blood vessels, and almost everyone has a big difference. If I had done this surgery, I would never touch the spinal cord artery."

As he said that, he paused and pointed to the images on the big screen excitedly.

"If I did it, my body could no longer bear it. The movements would be a little bit distorted, and I couldn't be so accurate. Look at Mr. Zheng's technique, it gave me an illusion that it seemed to be getting better."

Director Pan was stunned.

I was undergoing surgery with dozens of kilograms of lead clothes. It has been nearly three hours, but I can still get better? Isn’t this a joke?

Ancient generals had all their armors and armor, so the time they could exert their strongest combat power was limited.

Is Zheng Ren possessed by Zhao Zilong, who was in and out of Changshan?

Super-selected spinal cord to provide artery for success, but the angiography is still not the one that supplies blood to the first half of the liver tumor.

While disappointed, the people in the operating room were a little grateful.

If it is this blood vessel, it means that the operation cannot continue.

For aortic angiography, Zheng Ren selected several suspected vascular superselected blood vessels, but none of them were tumor-providing arteries.

The stomach is short...intercostal...no signs of blood supplying tumors are found in each artery.

Just like looking for a needle in a haystack, Zheng Ren had no other way, he could only try it a little bit.

None of them...

Zheng Ren recalled carefully, searched and searched in the master-level intervention memory.

Or is it a phrenic artery? Not sure, the chance is very small, but you need to try it.

Just as the phrenic artery was about to be selected, a ding dong suddenly came from Zheng Ren's ears.

[The doctor's parents' heart (2) task time counts down.]

【ten……】

【Nine……】

Zheng Ren was stunned for a moment, and he forgot that he had another task.

I took a look at the task prompt in the upper right corner of the field of view and the completion rate is now 62%, which can be considered as a completion.

【five……】

【Four……】

If it ends now, you should be able to receive a reward. Whether it is skill points or experience points, they are all needed by Zheng Ren.

But he just hesitated for a moment and ignored the emotional fluctuation of the system's mechanical female voice, and began the super selection of the diaphragm artery stubbornly and stubbornly.

System tasks?

Let that big pig's hoof get out!

It's no big deal if a task is not completed.

After counting down the system mechanical female voice, it disappeared into the air. Zheng Ren didn't care about it at all, but carefully selected the diaphragmatic artery.

The micro guidewire super selected successfully...

Microcatheter enters...

The high-pressure syringe began to inject contrast agent, and the dose was controlled by Zheng Ren very finely.

As the contrast agent enters the diaphragmatic artery, after 1 second, the upper part of the liver tumor appeared half-hiddenly on the large screen in the catheter room operation room like a shy girl.

"Wow!" Chu Yan jumped up suddenly.

Chu Yanran let out a sigh of relief and put her body on the wall. She was too nervous before, and once she relaxed, her legs became weak.

Director Pan waved his fist with his right hand, as if he had watched the soldiers brave the enemy's dense artillery fire, climb to the main peak, start fighting for bayonets, and take down the position.

Professor Pei leaned back on the back of the wheelchair and closed his eyes slightly.

Next, there is no difficulty at all, and it is all routine operations.

This young man...

It's a must!

Ten minutes later, the operation ended.

Zheng Ren took a piece of sterile gauze and pressed the patient's femoral artery puncture point.

Su Yun lowered his head and walked in, pressed his hand on the gauze, and leaned Zheng Ren away with his shoulder without saying a word.

This guy was angry. Zheng Ren wanted to say something, but he was still stupid, so he finally held it back.

He tore off the sterile surgical gown and threw it into the contaminated bucket. Zheng Ren walked out of the operating room.

It was already dark outside, and time passed so quickly, Zheng Ren sighed.

A bottle of water appeared in front of her and it was Xie Yiren.

Zheng Ren smiled, thanking clumsyly.

"Mr. Zheng, thank you." Chang Yue expressed his most sincere gratitude deep in his heart with a little dullness.

"It should be." Zheng Ren took the pure water and took a big sip.

"Xiao Zheng, come here." Professor Pei smiled and waved to Zheng Ren.

Zheng Ren responded and walked over.

"Which hospital should you have studied your skills?" Professor Pei asked: "Or you have practiced with your tutor when you were in school."

Zheng Ren smiled and said nothing.

Professor Pei just expressed his appreciation and did not want to get an answer.

"After a while, we will hold a national annual meeting to participate in the subject. Are you interested in participating?" Professor Pei sent an invitation.

"Depending on the situation, I... I am actually a surgeon." Zheng Ren said.

"Um?"

"My doctor's certificate registration scope is general surgery," Zheng Ren explained. "Because I was transferred to the emergency department some time ago, I can also do related emergency surgery."

Seeing Zheng Ren anxiously explaining, Professor Pei smiled, "I'm not asking you this, what are you anxious about? His level is indeed good, his talent is very high, and he is very patient."

Seeing that Professor Pei praised him, Zheng Ren smiled shyly.

Director Pan asked with concern: "Are you tired? Do you want to go and have a rest?"

"Not tired." Zheng Ren stood upright, just right, and Director Pan made a punch and hit Zheng Ren's chest.

This is a habit in the army, which means praise or praise. But in the hospital, no one does this, especially Zheng Ren, who stood for four hours in the operation and was wearing a lead suit worth dozens of kilograms.

Director Pan immediately woke up and felt a little embarrassed.

Zheng Ren quickly hammered his chest with his fist, making a bang sound to show that he was fine, just like the orangutan climbing up the Empire State Building.

"Xiao Zheng, what is your education?" Professor Pei smiled.

"postgraduate."
