Back in 2002 as a doctor

Although this is not an epoch-making scene, it only belongs to the breakthrough evolution of a certain branch of interventional surgery, but it is enough!

After a long time, someone let out a soft cry.

The voice was very light, carrying the inexplicable emptiness of a sage's moments.

Surgery can still do this!

Different from the previous thrombectomy, the latter uses a machine. As long as the various values ​​are adjusted, the operation becomes very simple.

Those doctors who laughed at Olida before for finding a sky-defying magician knew that Olida had already developed an even more heaven-defying machine!

Chapter 0728 welcome their king

Professor Michael was standing behind Zhou Congwen in the operating room, staring at the mechanical thrombus suction device in a daze.

He doesn't understand how machines work.

But everything that Zhou Congwen showed showed him one thing—no matter how compliant and operable the suction catheter he made was, the moment this machine appeared, it was already out of date.

It can still be used, but who doesn't want to use this kind of mechanical suction?

Although thrombus aspiration is only a small branch of cardiac interventional surgery, it is a very important branch.

Professor Michael was fascinated by watching it, but at the same time lost his mind.

All of this was far beyond his understanding of interventional surgery, but only a little bit. Thinking about it carefully, Zhou Congwen's surgery was all reasonable.

Professor Michael felt that he could think of it and make it if he worked a little harder.

It's a pity that I don't have one.

"Zhou, how did you think of it?" Professor Michael asked in a daze.

"Heh." Zhou Congwen smiled, but did not answer Professor Michael's question.

He was absent-minded for a while before he asked this unanswerable question, although Zhou Congwen had the answer.

This was originally the routine operation of later generations, but it appeared about 10 years earlier.

Manual thrombus aspiration in patients undergoing direct percutaneous coronary intervention can improve TIMI blood flow and myocardial perfusion, reduce distal thromboembolism, and prevent no-reflow or slow blood flow.

However, based on clinical evidence based on a large-scale sample analysis in later generations, routine thrombus aspiration during direct percutaneous coronary intervention does not reduce the risk of death or reduce major adverse events, so routine use is not recommended.

Although this small machine has a limited audience, it has a relatively good effect on treating blood clots in the stent.

Zhou Congwen was too lazy to talk to Professor Michael, he just smiled and continued to complete the operation.

The next steps belong to the finishing work, simple and clear, and completed step by step.

"Shen Lang, you understand now."

Shen Lang nodded.

"Actually, it's not difficult, just go back and practice." Zhou Congwen said lightly, "However, you need to write down the surgical indications and possible side effects."

"En." Shen Lang's mind was full of the operation process, although it wasn't that complicated, it was not easy for a young doctor who just started.

"Zhou!" Professor Michael raised his voice behind him and asked.

"What's the matter, Professor Michael?"

"I feel that mechanical suction still has certain side effects." Professor Michael said in a low voice.

Zhou Congwen glanced back at him, knowing that the world's top surgeon was both unconvinced and academically researching, so he smiled, "I'll talk about the side effects of manual and mechanical suction when I go back later. "

Professor Michael did not expect Zhou Congwen's counterattack to be so quick and direct.

Manual aspiration of blood clots, I have studied for a long time, indeed there is a certain range of adaptation, but the side effects...

From the tone of the young man in front of him, it seemed that everything was under control.

why?

Professor Michael was a little confused.

This is not scientific at all.

"Doctor Zhou." A doctor in Cleveland said respectfully, "Are you really going to tell me?"

"Shouldn't everyone talk about it after the demonstration operation?" Zhou Congwen smiled slightly, "There is no such rule in Cleveland?"

The doctor was sweating profusely and shook his head again and again.

"Send the patient back. You may not be able to hear the lecture, but there should be a video." After Zhou Congwen finished speaking, he removed the sterile sheet and turned to leave.

Shen Lang followed behind Zhou Congwen, wanting to ask a lot, but he didn't know what to ask when the words came to his lips.

"Shen Lang, see everything clearly."

"See clearly." Shen Lang said in a low voice.

Zhou Congwen glanced at Shen Lang with a smile, "There are still many surgical methods, I hope you can get in touch with them within a year."

"Can I learn it?" Shen Lang had no confidence.

"Why can't you learn?" Zhou Congwen laughed, didn't continue to say anything, went to change clothes and left the locker room.

A group of people stood darkly at the door of the locker room, Shen Lang was dumbfounded.

This is……

"Thank you, Doctor Zhou." A bald, middle-aged man warmly walked up to him and extended his hand in greeting.

Zhou Congwen shook hands with him.

"I didn't expect this product display to be so successful."

"Dear Mr. Chairman, the product display is not over yet." Zhou Congwen said with a smile, "Prepare the courseware, and there will be a lecture next."

"Lecture?"

"There is an analysis of the advantages and disadvantages of manual and mechanical aspiration." Zhou Congwen said.

Olida's senior management was stunned.

In their view, this is no longer a tit-for-tat, but a vengeance and a never-ending death.

Lan Ke chased after Olida's new product, but it was a comparison, and the outcome was in the hearts of the doctors.

But Zhou Congwen wanted to make a comparison right away, and beat Lan Ke to death with a real hammer!

When Olida's executives thought about this level, some were excited, while others hesitated.

"Doctor Zhou, are you sure?" the man said hesitantly, "If there is a study on complications... I suggest waiting until there is a large-scale sample before doing it."

"Oh?" Zhou Congwen looked into his eyes, "I don't want Lanke's new products to be crucified in the coffin, but just for academic purposes. After this promotion, I believe that the new products will be released within 1-2 years." will spread all over the world.”

"The corresponding indications and complications must be told to the doctors present at the first time, so as to save a period of exploration."

Everyone in Olida fell silent.

What Zhou Congwen said is correct, and this is also one of the high-level propaganda of medical device companies.

but……

"Prepare the courseware." Zhou Congwen stopped talking to Olida's people, and said in an unquestionable tone.

The bald man had no choice but to explain to his assistant.

Ten minutes later, Zhou Congwen and Shen Lang returned to the exhibition hall.

The sound waves in the hall have turned into noise, echoing repeatedly, and the decibels are high.

But no one cared, the doctors discussed the details of the operation and its future application with red faces, and devoted themselves wholeheartedly.

After seeing how a blood clot was melted and witnessing the whole process, doctors from all over the world began to erupt after a brief silence.

They are excited, their minds are a little confused, and they feel uncomfortable if they don't say something.

When the people who saw Olida opened the door respectfully and stood on both sides bowed slightly, the boiling crowd realized that the magician who was like a god had returned.

They were stunned at the same time, and the crowd subconsciously separated, just like the myth recorded in Exodus.

meet their king.

follow their king.

To open up a whole new world.

Chapter 0729 Zhang You Every Second Wrong

When Shen Lang saw the crowd in front of him being separated by an invisible hand, and the top interventional cardiologists from all over the world greeted Zhou Congwen with the etiquette of their own country, the fire in his heart ignited.

Not the fire of gossip, but envy, even jealousy, an old saying rang in his ears.

Alas, a man should be like this!

Shen Lang hesitated for a moment, instead of following Zhou Congwen to accept the courtesy from doctors from all over the world, he walked around quietly and walked to Zhang You's side.

"Director Zhang, are you tired?" Shen Lang asked in a low voice.

Zhang You stared blankly at Zhou Congwen walking through the crowd, like a star, constantly shaking hands with those who extended his hand, and he didn't know what it was like.

"Director Zhang? How about I send you back to rest?" Seeing that Zhang You didn't speak, Shen Lang asked again.

"I..." Zhang You sighed, feeling inexplicably sad.

He never expected to reach Zhou Congwen's level, he didn't even dare to think about it, he couldn't even dream of it.

Seeing which one Zhou Congwen walked to the display stand, Zhang You asked in a daze, "Shen Lang, is the machine easy to use?"

"It's okay, but Congwen said there are certain indications, and the indications are very limited." Shen Lang replied truthfully.

Zhang You no longer has any delusions.

In the past, he would have hoped that since there are certain indications, it will prove that there are still many untreatable patients in cardiac interventional surgery, which means that cardiac surgery is necessary.

But now Zhang You doesn't have any unreasonable thoughts.

In the soil of Zhou Congwen's hometown last week, the schematic diagram of the operation drawn by Congwen silently told Zhang You that waiting is like boiling a frog in warm water, and it will die unconsciously.

When that day came, I didn't even have the strength to struggle.

In a daze, Zhou Congwen had already walked in front of the screen, calmly looked at the densely packed crowd, and said calmly, "Time is limited, so to make a long story short, let me talk about the complications related to thrombus aspiration."

A brand new machine appeared. After the successful operation, what the surgeon said was not the advantages of this machine, but the corresponding complications!

The faces of Olida's relevant personnel were dark and unsightly.

The doctors present also looked at Zhou Congwen dumbly, not understanding what he meant.

"First of all, the decrease in blood pressure and heart rate caused by manual aspiration of thrombus may be due to the following situations.

First, vascular occlusion or spasm;

Second, recanalization leads to reperfusion injury.

In either case, the operator should promptly withdraw the suction catheter and proceed accordingly. "

"Embolic shedding during thrombus suction and withdrawal can lead to complications such as non-infarction-related arterial embolism and cerebral embolism, which can be divided into the following points..."

Zhou Congwen talked eloquently, but Zhang You and Shen Lang couldn't understand what Zhou Congwen was talking about.

It's not because of professional barriers, but because Zhou Congwen's English level is too high, as proficient as his mother tongue, and he has a bit of an accent from the Great Lakes region.

Zhang You and Shen Lang looked at each other, feeling lonely.

"Oh." Zhang You sighed.

"Congwen told me before that he managed to pass CET-[-] before graduation. This kid is talking nonsense." Shen Lang looked at Zhou Congwen and said helplessly.

"Hehe." Zhang You smiled.

He wanted to say that Zhou Congwen had been hiding something.

But when the words came to his lips, he felt that this was not the case at all - Zhou Congwen could crush everything with his strength, so why bother to hide it.

"Director Zhang, you look tired, shall I take you back to the hotel?" Shen Lang asked.

"No need." Zhang You looked at Shen Lang's face, like a friend of his when he was young.

It's not that they look alike, but that their youthful and ignorant temperament is no different from that of their friends.

"Then you..."
