The Surgeon's Studio

Chapter 621: Was Really Aggrieved

The top of the coronary artery plaque rotary grinding catheter was a metallic stainless steel drill head embedded with fine diamond particles. The catheter entered the blockage position of the coronary artery and Zheng Ren opened the drill head.

The drill head was welded to a long and soft spiral rotating catheter, driven by a gas turbine connected to it to rotate at a high speed of 180,000 to 200,000 rpm.

When the drill head rotated at high speed, it could grind the plaque into small debris and wash it to the far end. The debris could then pass through the capillary bed.

There was a cavity in the catheter to pass through a 300cm long guide wire as thin as 0.25cm.

The driving shaft was installed in the 4.3 F polyethylene sheath pipe. During operation, the sheath pipe was pressurized by 40 KPA and continuously washed with normal saline to cool and lubricate it.

The patches were being worn away bit by bit, but Zheng Ren’s expression did not relax. His two thick eyebrows were knitted together.

It was different from what he had imagined. Even with a Grandmaster level of interventional surgery, it was still very difficult to do it... However, he needed to be assured that he could complete the surgery.

It seemed that he would need to use more of his surgical training time...

Although he had plenty of time, Zheng Ren still used every minute and every second of his surgical training time very carefully.

Only God knew when these training sessions would be of great use.

No wonder the circulatory intervention doctors at the Karolin Medical and Surgical Research Institute in Stockholm did not dare to do it. It was really f*cking difficult to find head from tail.

Bang... Zheng Ren seemed to be able to hear a crisp sound.

The coronary artery had been worn out and fresh blood instantly filled the pericardial cavity.

If this was outside, the emergency department would have done a major rescue. They would open up the chest cavity to solve the problem of cardiac tamponade.

With Dr. Mehar’s physical condition, he would be declared clinically dead.

Zheng Ren’s forehead was sweating.

The operation failed.

Again!

Another operation. Failure five minutes later.

Again!

Zheng Ren was focused on the operation in the operating theater of the system. He did not notice the passage of time in reality.

In the blink of an eye, the 22 consecutive days of surgical training ended.

528 hours, 31,680 minutes. The boring and repetitive training was done in one go.

Zheng Ren was not tired. Instead, he was filled with a strange excitement.

Zheng Ren treated things that required great perseverance as entertainment. It was like playing games all night. More than 30,000 minutes had passed in the blink of an eye.

He did not eat, drink, rest, nor sleep. However, the surgery was finally a success!

It was not a random success. Zheng Ren performed thirty consecutive coronary artery occlusion surgeries similar to Dr. Mehar’s. The completion rate of the surgical progress bar was 100%.

However, it was not the end. It was just the beginning.

Because of Dr. Mehar’s abnormal blood clotting condition, just opening the coronary artery was far from enough.

Zheng Ren absolutely did not want the surgery to succeed. A few months later, Dr. Mehar would have to face the same problem again.

Just because he could open it this time did not mean that he could do it again.

The trauma of the surgery, no matter how high the level, 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 he would be able to successfully perform the rotary grinding technique again.

Even if he succeeded, he would only be able to extend the patient’s survival time by a few months. After that, he would have to face the same situation endlessly.

Zheng Ren did not step down when the surgical progress bar was 100% complete. Instead, he took out a recyclable stent and studied it.

This recyclable stent with a membrane was the kind that was commonly used in the clinic.

Zheng Ren thought for a long time, which was rare, before he finally put the recyclable stent in.

The simulation mannequin opened up the experimental subject’s coronary artery, and the red color on the experimental subject’s system panel quickly faded.

The surgery should be over by then.

However, Zheng Ren did not move. He was a little worried, worried that the System would not understand his intentions.

However, his worry was unnecessary.

With a thought, the experimental subject lay motionlessly in the operating theater of the system. The simulation mannequin did not move.

A few months seemed to have passed, and the stent was filled with blood clots.

It was what Zheng Ren was thinking about. Whether or not the patient’s surgery could be considered a true success depended on this.

He carefully opened the capsule of the recyclable stent and placed another absorber. He turned the frequency to a certain range and absorbed the blood clots that fell off.

He removed the membrane stent bit by bit. He was very careful. It was still very difficult to achieve a Legend-level surgery.

Unfortunately, if nothing unexpected happened, some blood clots still fell off and flowed into other blood vessels, causing an arterial embolism.

The simulation mannequin showed a cerebral infarction.

Although the surgery failed, Zheng Ren smiled.

It was the first time he smiled after entering the System’s operating theatre.

There was no problem with his train of thought, but his operating methods still needed to be improved.

That was good. As long as there was no problem with the direction, everything was fine.

It was another round of continuous surgical training. Even as a Grandmaster-level surgeon, Zheng Ren was still having a very difficult time.

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 covered stent that was full of blood clots. The next step was simple. He would just need to add a new stent.

The only problem with this new technique was that the cost on the patient was relatively high.

In a few months, the next stent would have to be taken, and the corresponding medicine would have to be taken orally for the anticoagulation treatment.

However, it was still a way, was it not?

After using nearly 10 hours, Zheng Ren familiarized himself with two more techniques before he left the System’s space with a smile.

..

In the observation room of the clinical decision unit at Karolin Medical and Surgical Research Institute in Stockholm, Su Yun was still fiddling with his phone with his head lowered, chatting with some unknown girl.

The professor was still not back yet. A few doctors were still concentrating on recording every value and performing professional analysis on the patient.

Zheng Ren knew that once the condition changed, they would press the corresponding button and find the most professional doctor to deal with Dr. Mehar.

However, none of that had anything to do with Zheng Ren. With a smile on his face, he leaned back against his 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 he got his confidence from. He actually believed that Zheng Ren could perform the kind of surgery that was difficult even for a Master-level surgeon.

“It’s not a 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 at his hair. “I’ll go help the professor in a while.”

“Help him with what?” Zheng Ren was surprised.

“His mouth is even dumber than the waistband of his cotton pants. Of course, he can’t win a quarrel. I’ll go help him argue and get this surgery,” Su Yun said with a smile. He seemed to be in a good mood.

“Well, you’re good at that stuff. Go ahead. I’ll wait for your good news here,” Zheng Ren stretched and said lazily.

Su Yun’s face changed. Was Zheng Ren insulting him?

He was good at talking but not in surgery?!

However, Zheng Ren was the opposite.

Su Yun felt wronged... F*ck, he had to carry out a human heart transplant surgery again so that Zheng Ren would not think that his surgery was not good enough!
