Chapter 984 It Was Wrong From the Beginning

"It's different, the sympathetic nerve is not involved in heart transplantation." Su Yun replied.

He had a rare serious expression on his face, and when he talked about heart transplantation, he felt professional and confident.

"How much do you know about testing the nervous system?" Zheng Ren asked.

"I'll ask my friend who is doing research." Su Yun took out his mobile phone and began to look through the phone book.

Zheng Ren was very emotional. A sharp-tongued bitch like Su Yun has friends all over the world. When he came to the capital to participate in the prostate project before, Fang Lin and Zhao Yunlong heard the news and dragged him to drink.

Haicheng knew the little girl from Migou House, and she seemed to have a good relationship.

Now that he wants to ask about nervous system testing, he can also pick up his mobile phone and find someone for consultation.

Do people nowadays like sharp-tongued guys? Or is it that people with good looks are born to be loved by everyone?

But this is not important, Zheng Ren wants to know what equipment can detect nerves, and then see if the system space is available for sale.

You can’t just buy it blindly. The experience value can be regarded as a general point. You can buy equipment and surgery training time. This kind of thing is like money, who would think too much? Since I have the system, I don't seem to be interested in money, and it may also be because there is a better means of equivalent exchange than money.

Zheng Ren fell into deep thought without thinking, and his thoughts had already flown nine days away.

Soon, Su Yun got the news.

"Neural current sensors, domestic ones cost hundreds of thousands, and imported ones are more expensive. Boss, why do you want this thing?" Su Yun felt strange and asked.

"Patients with renal artery stenosis always feel that they need to be surgically stripped, but you know the nerves, you can't do it casually." Zheng Ren sighed, and at this point, no matter what Su Yun asked, he stopped talking.

If you say too much, you will lose. The ancients were sincere and did not deceive themselves.

As long as Su Yun is given a thread, he can find more things that need to be explained by himself. It's best not to talk about things involving the system.

Su Yun was just a little strange, and would never think of the big pig's hoof of the system anyway. Seeing that Zheng Ren was in a slightly weird mood, he guessed that the patient with renal artery stenosis had not made a breakthrough, so he comforted Zheng Ren a few words and went to rest.

Back in the system space, Zheng Ren opened the panel of the system mall and looked through the directories one by one.

Nerve current sensor... This kind of thing is generally used by people who do basic research, and it is basically not used in surgery.

After searching for 20 minutes, Zheng Ren discovered that there is indeed a medical nerve current sensor in the system mall at a very low position.

200,000 experience points...

Seeing this price, Zheng Ren almost spat out a mouthful of old blood.

One day's surgical training time is 86,400 experience points, and a neural current sensor is worth more than two days of surgical training time.

It's—what the hell.

Zheng Ren hesitated bitterly for a while, and finally clicked to buy. After all, this is considered an investment, and I look forward to a greater output. Moreover, Zheng Ren was also very curious about the side effects of radiofrequency ablation leading to the adhesion of blood vessels and nerves.

A small black thing that looked particularly textured appeared in front of Zheng Ren. Zheng Ren didn't appreciate the black technology of the system at all. He felt overwhelmed when he saw that he lost a lot of time for surgery training.

Along with the nerve current sensor, which fell into Zheng Ren's hands, there was also a user manual.

After Zheng Ren read the guide, he felt a little emotional about how difficult it is to do basic research. But now he didn't have the time to think too much about it. He spent a lot of money once, and the first thing he had to face was the lack of time for surgical training.

It's better to do more tasks. It seems wrong to ignore the task rewards. Zheng Ren corrected some of his behavior errors, re-entered the system operating room, and started another operation.

The test subject was still lying on its side, peeled off layer by layer, and saw the stenosis of the renal artery. Zheng Ren carefully separated the renal sympathetic nerve that fused with the blood vessels, and his technique was delicate and gentle, and he played 120% of the level.

After freeing a corner, Zheng Ren hooked up the wire of the neural current sensor.

According to the instructions for use, Zheng Ren adjusted the current and performed electrical stimulation on the renal sympathetic nerve.

However, Zheng Ren was dumbfounded.

The fusion point was stimulated by a weak bioelectricity, and the experimental subject did not respond at all.

The big pig's hoof is down? As soon as this idea appeared, Zheng Ren denied it.

impossible!

If it wasn't for this reason, could it be... Zheng Ren was stunned for a moment, and began to carefully observe the direction of the renal sympathetic nerve.

The life and death of the experimental subject is no longer important.

This operation is bound to fail. There was something wrong with the local dissection done before, and Zheng Ren quickly recognized this.

Sure enough, Zheng Ren's operation speeded up, and the test subject's blood pressure rose due to the stimulation of the renal sympathetic nerves, causing cerebral hemorrhage, and died immediately.

And Zheng Ren continued to do local dissection, starting from the initial segment of the renal sympathetic nerve, and searching for it bit by bit instead of retrograde. This is more troublesome, the scope to be stripped is larger, and the danger is also multiplied.

However, Zheng Ren had no choice.

Surgery under a microscope at 20X is very tiring. But Zheng Ren didn't dare to blink his eyes, for fear of missing something.

It took a long time before he finished dissecting the renal sympathetic nerve.

It turned out that everything was wrong before!

The fusion section of the renal artery and the renal sympathetic nerve looks like the section of the nerve, but it is not! That's a piece of connective tissue. It just looks thick and follows the shape of the renal sympathetic nerve, which is easily mistaken for the renal sympathetic nerve segment.

Whereas the true renal sympathetic nerves are buried underneath, nearly fused with the adventitia of the vessel.

Zheng Ren let out a long breath, and the difficulty of the operation was further increased. But it doesn't matter, if you find the reason for your repeated failures, then the next thing to do is simple.

After all, the level of surgery is here. If you find the problem, there is nothing special, just follow the steps.

Zheng Ren started a new operation.

It was cut open to find the stenotic segment of the renal artery, and the position that was previously thought to be the renal sympathetic nerve was directly severed, and the subject did not respond at all.

After layers of connective tissue less than 1mm were bluntly separated, Zheng Ren finally saw where the renal sympathetic nerves were located.

Under a 20X microscope, all operations will be magnified. He held his breath and concentrated, releasing the renal sympathetic nerves little by little.

This time the experimental subject did not die, and the state did not change.

Looking at the dissociated sympathetic nerves, Zheng Ren knew that the operation was basically a success!

Next comes interventional surgery.

Puncture, hyperselection, stent entry.

When the brace was opened, Zheng Ren's heartbeat seemed to have stopped.

The numbers displayed by the ECG monitor connected to the experiment body were very stable, without major fluctuations.

With the stent fully opened, the number of experimental subjects who died after a certain period of time did not appear.

Zheng Ren didn't celebrate, but started to flush and shut his abdomen.

After finishing the last stitch, he looked up.

The degree of completion of the operation - 97%!
