The top of the coronary plaque rotary grinding catheter was a metal stainless steel drill head with fine diamond particles.
The catheter entered the coronary artery blockage and Zheng Ren opened the drill head.
The drill head was welded to a long and soft spiral rotating catheter. It was driven by a gas turbine behind it to rotate at high speed. Its speed was 180000 to 200000 revolutions per minute.
When it rotated at high speed, it could grind the atherosclerotic plaque into fine debris and wash it to the distal end. The debris could pass through the capillary bed.
There was a cavity in the catheter for a 0.25cm, 300cm long guide wire to pass through.
The drive shaft was installed in a 4.3F polyethylene sheath tube. During operation, the sheath tube was pressurized by 40kPa and continuously rinsed with normal saline to cool and lubricate it.
The plaque was worn off bit by bit, but Zheng Ren's expression did not relax. His two thick eyebrows furrowed.
It was different from what he had imagined. Even with the level of a Legend in interventional surgery, it was still very difficult … to complete the surgery.
It seemed that he would have to spend more time on surgical training …
Although he had a huge sum of money, Zheng Ren still used every minute and second of surgical training time very carefully.
God knew when this training would come in handy.
No wonder the circulatory interventional doctors from the Karolin Medical and Surgical Research Institute in Stockholm did not dare to do it. He only realized how difficult it was when he started.
"Pa …" Zheng Ren seemed to hear a crisp sound.
The coronary artery had been worn out …
Blood instantly filled the pericardial cavity.
If this was outside, it would have been an emergency rescue. He would have opened the chest and solved the problem of cardiac tamponade.
With Dr. Mehar's physical condition, he could be declared clinically dead.
Sweat broke out on Zheng Ren's forehead.
The surgery failed.
Again!
Another surgery was declared a failure after five minutes.
Again!
Zheng Ren was in the operating theater of the System. He was focused on the surgery and did not notice the passage of time in the other dimension.
In the blink of an eye, 22 consecutive days of surgical training were over.
528 hours, 31680 minutes. The boring and tedious training was done in one go.
Zheng Ren was not tired. Instead, he was filled with a strange excitement.
Something that required great perseverance to do, Zheng Ren treated it as entertainment. It was like playing games all night. More than 30,000 minutes passed in the blink of an eye.
No eating,
No drinking,
No rest,
No sleep.
However, the surgery was still successful!
It was not an accidental success. Zheng Ren performed thirty consecutive coronary artery occlusion surgeries similar to Dr. Mehar's, and the completion rate of all the surgeries was 100%.
But this was not the end. This was just an accident, a beginning.
Because of Dr. Mehar's abnormal blood coagulation, opening the coronary arteries was far from enough.
Zheng Ren definitely did not want the surgery to be successful. A few months later, Dr. Mehar would have to face the same problem again.
Just because it could be opened this time didn't mean it could be opened next time.
No matter how skilled the surgeon was, the trauma from the surgery would be left behind. Moreover, Dr. Mehar was still aging and his body was gradually changing.
Next time, even Zheng Ren could not guarantee that the spinning grinding technique would be successful.
Even if it was successful, it could only prolong the patient's survival for a few months. After that, the patient would have to face the same situation endlessly.
Zheng Ren did not step down when the surgery was 100% complete. Instead, he took a recyclable stent and studied it.
This recyclable stent with membrane was the kind that was commonly used in clinical practice.
Zheng Ren considered it for a long time, which was rare for him. Only then did he place the recyclable stent in.
After opening the experimental subject's coronary artery, the remaining red color on the system panel quickly faded.
The surgery should be over at this point.
However, Zheng Ren did not move. He was a little worried. He was worried that the System would not understand his intentions.
However, his worries were unnecessary.
With a thought, the experimental subject lay motionless in the System's operating theater.
A few months seemed to have passed, and the stent was filled with blood clots.
This was what Zheng Ren was thinking about. Whether the patient could be considered a true success of the surgery or not would depend on this.
He carefully opened the balloon of the recyclable stent and put down an absorber. He turned the frequency to a certain range to absorb the blood clots that fell.
He removed the membrane stent bit by bit. He was very careful. It was still very difficult for a Legend-level surgeon to do it.
Unfortunately, as expected, there were still blood clots that fell off and flowed into other blood vessels, causing an arterial embolism.
It was reflected in the experimental subject, and the symptom was cerebral infarction.
Although the surgery had failed, Zheng Ren smiled.
This was the first time he smiled since entering the System's operating theater.
There was no problem with the idea, but the operation method still needed to be improved.
That was good. As long as there was no problem with the direction, everything would be fine.
It was another round of continuous surgical training. Even with Zheng Ren's Legend-level surgical skills, it was still very difficult.
This time, it did not take that long. After 21 hours and 44 minutes of surgical training, Zheng Ren was already able to skillfully remove the membrane stent that was full of blood clots. The next step was simple. He just needed to add a new stent.
The only problem with this new surgical method was that the cost of the patient was relatively high.
In a few months, the next stent would be needed, and the corresponding drugs would be taken orally for anticoagulation treatment.
But after all, there was a way, right?
It took Zheng Ren another 10 hours to familiarize himself with the two surgical methods. Only then did he leave the System space with a smile.

In the observation room of the Karolin Medical and Surgical Research Institute in Stockholm, Su Yun was still playing with his phone with his head down. No one knew which girl he was chatting with.
The professor still had not returned. A few doctors were still focused on recording every value and conducting professional analysis.
Zheng Ren knew that once there was a change in the condition, they would press the corresponding button and find the most professional doctor to deal with Dr. Mehar.
However, this had nothing to do with Zheng Ren. With a smile, he leaned back and leaned against the chair.
Seeing that Zheng Ren finally moved, Su Yun put down his phone.
"Boss, there's no problem, right?" Su Yun did not know where his confidence came from. He actually believed that Zheng Ren could do this kind of surgery that was very difficult even for a Legend-level surgeon.
"No problem," Zheng Ren said.
After a pause, Zheng Ren said with certainty, "There's no problem at all!"
"That's good." Su Yun smiled and blew. "I'll go help the professor in a while."
"Help him with what?" Zheng Ren was surprised.
"His mouth is even stupider than the waist of his cotton pants. Of course, he can't win an argument. I'll go help him argue and get this surgery, "Su Yun said with a smile. It seemed that he was in a good mood.
"Well, you're better at arguing. Go. I'll wait for your good news here," Zheng Ren said lazily as he stretched his back.
Su Yun's expression changed. Was Zheng Ren mocking him?
He was good at arguing but not good at surgery?!
However, looking at Zheng Ren, it did not seem like it.
Su Yun felt aggrieved … F * ck, he had to start a human heart transplant again and make this guy feel that his surgery was not good enough!
