"It's different. Heart transplantation does not involve the sympathetic nervous system." Su Yun replied.
There was a rare serious expression on his face, and once he talked about heart transplantation, he felt professional and confident.
"How much do you know about nervous system testing?" Zheng Ren asked.
"Let me ask my friends who are doing research." Su Yun took out his cell phone and started flipping through the phone book.
Zheng Ren was very impressed that a sharp-tongued girl like Su Yun had friends all over the world. When he came to the imperial capital to participate in the prostate project, Fang Lin and Zhao Yunlong came after hearing the news and took him to drink.
Haicheng knows the little girl from Migou House, and seems to have a good relationship with her.
Now that he wants to ask about neurological testing, he can pick up his phone and ask someone for consultation.
Do people nowadays like sharp-tongued guys? Or is it that people with good looks are born to be favored by everyone
But this is not important. Zheng Ren wants to know what equipment can detect nerves, and then see if there is any for sale in the system space.
You can't buy it blindly. The experience value can be regarded as a general point. You can buy equipment and surgical training time. This kind of thing is just like money. Who can have too much? Ever since I established the system, I don’t seem to be interested in money anymore, maybe because there is a better means of equal exchange than money.
Zheng Ren was lost in thought, and his thoughts were nine days away.
Soon, Su Yun got the news.
"The domestically produced neural current sensor costs hundreds of thousands, and the imported one is even more expensive. Boss, what do you want this for?" Su Yun felt strange and asked.
"I always feel that patients with renal artery stenosis need surgical stripping, but as you know, the nerves cannot be removed casually." Zheng Ren sighed. At this point, he stopped talking no matter how Su Yun asked.
If you talk too much, you will be wrong. The ancients are sincere and I will not deceive them.
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 going to this big pig's hooves like the system. Seeing that Zheng Ren was in a strange mood, he guessed that the patient's condition might be due to renal artery stenosis and had not yet broken through. He comforted Zheng Ren with a few words and went to rest.
Returning to the system space, Zheng Ren opened the system mall panel and looked through the catalogs one by one.
Nerve current sensors... This kind of thing is generally used by people doing basic research, and is basically not used in surgery.
After searching for twenty minutes, Zheng Ren discovered that there was indeed a medical nerve current sensor in the system mall at a very low position.
200,000 experience points…
Seeing the price, Zheng Ren almost spit out his blood.
One day of surgical training time is worth 86,400 experience points, and a neural current sensor is actually worth more than two days of surgical training time.
What a special thing.
Zheng Ren hesitated bitterly for a long time, and finally clicked to buy. After all, this is considered investment, and we look forward to greater output. Moreover, Zheng Ren is also curious about the side effects of radiofrequency ablation that causes blood vessels and nerves to stick together.
A black, textured little thing appeared in front of Zheng Ren. Zheng Renze didn't appreciate the black technology of the system at all. He was heartbroken when he saw that a lot of surgical training time was suddenly lost.
Along with the nerve current sensor, there was also a user guide that fell into Zheng Ren's hands.
Zheng Ren read the guide and felt a little emotional about how difficult it is to do basic research. But now he doesn't have the time to think too much and spends lavishly. The first thing he has to face is the lack of time for surgical training.
It was better to do more tasks and ignore the task rewards. It seemed wrong. Zheng Ren corrected some of his behavioral errors and re-entered the system operating room to start another operation.
The experimental subject was still in the side-lying position, and was peeled off layer by layer to see the renal artery stenosis. Zheng Ren very carefully separated the renal sympathetic nerves that were fused with the blood vessels. His technique was delicate and gentle, and he performed at 120% of the level.
After freeing a corner, Zheng Ren connected the line of the nerve current sensor.
According to the instructions for use, Zheng Ren adjusted the current and electrically stimulated the renal sympathetic nerves.
However, Zheng Ren was confused.
The fusion point was stimulated by weak bioelectricity, and the experimental subject showed no reaction at all.
Big Pig Hoof is down? As soon as this idea came up, Zheng Ren rejected 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 nerves.
The life and death of the experimental subjects is no longer important.
This operation is bound to fail. There was something wrong with the local anatomy done before, and Zheng Ren quickly realized this.
Sure enough, Zheng Ren's operation speed was accelerated, and the experimental subject's blood pressure increased due to stimulation of the renal sympathetic nerve, cerebral hemorrhage occurred, and he died immediately.
Zheng Ren continued to perform local dissection, starting from the initial segment of the renal sympathetic nerve and searching bit by bit instead of going retrograde. This is more troublesome, the scope that needs to be stripped is larger, and the risk is doubled.
However, Zheng Ren had no choice.
Surgery under a 20x microscope is very tiring. But Zheng Ren didn't dare to blink, for fear of missing something.
It took a long time before he completed the anatomy of the renal sympathetic nerves.
It turns out that everything before was wrong!
The fusion section between the renal artery and the renal sympathetic nerve looks like a nerve section, but it’s not at all! That's a piece of connective tissue. It just looks thick and follows the shape of the renal sympathetic nerve, so it can easily be mistaken for the renal sympathetic nerve segment.
The real renal sympathetic nerves are buried underneath, almost fused with the adventitia of the blood vessels.
Zheng Ren let out a long breath, and the difficulty of the operation was further increased. But that's not important. If you find the reason for 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 do it step by step.
Zheng Ren starts a new operation.
After incision, the stenotic segment of the renal artery was found. The location previously thought to be the renal sympathetic nerve was directly severed, and the experimental subject showed no reaction at all.
After layers of connective tissue less than 1 mm 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, freeing the renal sympathetic nerves bit by bit.
This time the subject did not die, and his condition did not change.
Looking at the freed sympathetic nerves, Zheng Ren knew that this operation was basically a success!
Next comes interventional surgery.
Puncture, super selection, stent entry.
When the stent was opened, Zheng Ren's heartbeat seemed to have stopped.
The numbers displayed by the ECG monitor connected to the experimental subject were very stable, without major fluctuations.
With the stent fully opened, no experimental subjects died after a certain period of time.
Zheng Ren did not celebrate, but began to rinse and close his abdomen.
After finishing the last stitch, he looked up.
The operation completion rate is 97%!
