Zheng Ren was in the operating room, concentrating on the operation.

In the end, he figured it out and practiced the latest positioning methods. It's just that the patient in front of me has not done the corresponding examination, and the theories that he has figured out cannot be put into practice.

Although it is meaningless for the surgery in front of him, Zheng Ren's surgical experience has improved a lot.

In the operating room, he has controlled the number of punctures between the hepatic vein and the portal branch to less than 10 times.

In the later stage, a TIPS operation can be completed in less than 2 hours, and even Zheng Ren has also made improvements in the prevention of postoperative hepatic encephalopathy.

This research and study has been of great help to Zheng Ren.

Although all the surgical training time and experience points accumulated in the early stage were exhausted, Zheng Ren believes that it is worth it.

Not only for slow surgery, but even for emergency surgery, Zheng Ren is very sure to take it down.

The puncture needle was sent to the overlapping position of the image, and Zheng Ren said in a deep voice: "Prepare for puncture." ”

Su Yun understood, and the guidewire was held steadily in his hand, motionless.

At this time, you don't need to be fast, you just need to be stable.

Zheng Ren reversed the direction, made the final adjustment, and pulled the puncture needle button.

Not surprisingly, the piercing failed.

He was not disappointed, because Zheng Ren knew that the purpose of this piercing was positioning, not success.

This puncture is only to leave a mark on the image as a target for marking.

Zheng Ren looked at the image intently, and already had the three-dimensional pattern construction of the patient's hepatic vein and portal vein in his heart.

"1.5cm upward, 15 degrees to the right. Zheng Ren said as he moved the guidewire.

Su Yun was stunned for a moment, it is said that in the operation, Zheng Ren's own operation is enough, the previous operations were like this, why did he tell himself? And there is also a right deviation of 15 degrees, what does that mean?

After a little pondering, Su Yun quickly understood what Zheng Ren meant.

Because the hepatic vein is very thick, the guidewire is too wide in the hepatic vein, resulting in constant drifting.

Zheng Ren definitely operated the guidewire, walked along the blood vessel wall, and used the blood vessel wall to help fix the guidewire. It's not very useful, but it's much better than being empty all around.

The issue of surgical techniques involved here is the feeling of accumulation of experience, and Su Yun knows.

As for the right deviation of 15 degrees, it is the angle that tells yourself that the hand should be held when fixing the guidewire.

Su Yun thought disdainfully, fortunately because of his high IQ, he really couldn't match it with another person. It's nice to have met yourself.

Zheng Ren also knew this, but these were all learned in the system operating room before the operation, and there was no time to communicate and communicate.

[Ha, it's the first time!]

In the apricot grove garden, there began to be a barrage count.

After many live broadcasts, all the doctors who watched the operation online for the first time had the illusion that the surgeon never fails.

They seldom gloat, but happily count to see how many punctures the surgeon can successfully complete the operation.

[This needle is a little far away.] 】

[It's a little far away, I don't know the intention of the magician.] If it was a stroke of luck, his luck really wasn't very good. 】

[I don't believe that the surgeon will blindly perform the puncture, the last embolization caused intestinal necrosis, and then the necrotic intestine was used to mark the bleeding point, you remember. At that time, I was in a daze, I didn't expect the surgeon to really do it. 】

Soon, under the barrage, the surgeon began the second puncture.

The black image of the puncture needle was a black lightning bolt.

The images of the portal vein and the hepatic vein overlap, and the image of the puncture needle stops immediately after the appearance of the puncture needle, and it is difficult to distinguish between the overlapping images of the portal vein and the hepatic vein.

[Did it work?]

[I don't know, this needle is in a particularly good position, and I have a feeling that the puncture has been successful.] 】

[Look at the next step of the operator's operation.] 】

The doctors in Xinglinyuan felt as if they had entered the operating room and were doing the operation themselves, and their hearts were hanging in their throats.

At first, some people said that the position of the first stitch was a little far, which was deliberate by the operator, and some people did not think so. However, judging from the position of the second injection, it was said that the surgeon was blind without purpose, and the doctors who watched the live broadcast did not believe it.

Even if it doesn't work, everyone inexplicably believes that the next shot will definitely succeed!

This is the confidence that dozens of live broadcasts of surgery bring to everyone.

In the operating room, Zheng Ren shook his head, looked at the image intently, and said, "0.3cm back, 10 degrees to the right." ”

He is like the captain of a small boat in the middle of the sea, fearless in the face of wind and waves, constantly giving orders.

And his crew, firmly executed, believed that under the command of the captain, the ship would definitely be able to overcome the wind and waves and reach the other side.

The guidewire retreats slightly, and if you don't feel acute, you can't feel the guidewire wandering at all.

0.3cm distance...... It's really hard to quantify.

Su Yun could feel the change of the guidewire, and after Zheng Ren stepped back the guidewire by 0.3cm, he held the guidewire in his hand, deviated 10 degrees to the right, and tried to fix the guidewire as much as possible.

Zheng Ren glanced again, and he was full of confidence at this time.

It is completely different from the system operating room! Zheng Ren returned to reality and had an experience after two punctures.

The system task rewards, and the accumulated luck value has reached the level of +6.

Although I didn't know what luck was used for, when I was doing TIPS surgery, Zheng Ren was keenly aware of the difference between reality and systematic operating room training.

The second needle was originally a trial puncture, and the main purpose was to locate the other side, and then determine that the portal vein was in between.

This is the technique that Zheng Ren has mastered.

However, the second needle almost smoothly entered the portal branch, only a little bit. At that moment, Zheng Ren had a realization that if his luck value was even 1 point higher, this needle would be there!

At this time, Zheng Ren is full of confidence!

If there is no needle, the next needle will definitely be successful!

As Su Yun fixed the guidewire, Zheng Ren began to pierce.

His fingers twitched the keys firmly.

But at this moment, the patient suddenly vomited violently.

As soon as his body moved, the position of the puncture needle shook violently. In this case, the god of luck did not favor Zheng Ren, and the third shot failed.

In the live broadcast room of the operation, there was silence.

Many people feel that they have succeeded when the puncture needle is ready for the puncture point.

[It's a pity......]

After a long time, a barrage slowly flew by.

[It's okay, it's just an accident, the next shot, it will definitely be successful!]

[The next shot, it is estimated that it will be positioned, and if you want to succeed, it still depends on luck. 】

【…… I suddenly felt a sense of despair, as if I had cut open the McCeremonial dot and could not see the appendix. 】

【Sweat...... That's a horror movie or not, not to mention the fact that you can't see the appendix by cutting the McSs point. I had an appendectomy the other day and it took me 3 hours. The appendix was last found near the splenic fossa. 】

[Sympathy upstairs.] 】

[Sympathy Upstairs +1]
