Wang Qingshan didn't know what others were saying about him, and even if he knew, he didn't care at all. In his opinion, people with black hair and yellow skin in the country are stupid.

Returning to the imperial capital and resting for one night, Wang Qingshan took Zheng Kaixuan to Pengcheng non-stop.

Although there was no preparation, Huaxia MicroPort still sent a car to pick up Wang Qingshan and his party after getting the news.

In any case, he is a powerful figure in cardiothoracic surgery in China, and he cannot be neglected. This is especially true for commercial companies like Huaxia MicroPort.

After eating early the next morning, Wang Qingshan did not go directly to the conference hall, but went back to the room and waited for a long time.

At ten o'clock at nine, after the start time of the meeting, Wang Qingshan took Zheng Kaixuan downstairs and walked to the conference hall with a swagger. Because he was not accompanied by a staff, Wang Qingshan was extremely dissatisfied, and his face seemed to have been gloomy since he went to Bajingzi.

At this time, his face was particularly gloomy.

"Xiao Zheng, tell me if Wu Mian doesn't have a little bit of pressure in his heart. Wang Qingshan said as he walked.

Zheng Kaixuan didn't speak, but followed half a step behind Wang Qingshan. Very cautious, he could feel Wang Qingshan's irritability.

"Occasionally, if you succeed in an operation, you really think you're awesome? You really think you can crush the world? Wang Qingshan didn't seem to want Zheng Kaixuan's answer, and said to himself, "How long has this technology been researched by Orchid? This man, why can't he clearly understand himself? ”

"Li Zhong, I've thought about it for the past two days, and I seem to be a little impressed. It was the poor boy from the north, the dark, sturdy doctor. I think it is more suitable for him to go to the orthopedic anti-thigh, and he can't do cardiothoracic surgery. ”

Listening to Wang Qingshan all the way, Zheng Kaixuan remained silent and didn't say a word.

Wang Qingshan muttered to himself as he strode towards the conference hall.

After many years of experience, Wang Qingshan was sure that there would not be many people coming, after all, the doctors in China were very busy, and when they suddenly announced that they were going to have a meeting, they rushed over?

Wu Mian really regarded himself as the leader of the martial arts alliance? Commanding the world, don't dare to disobey. I really don't know where his inexplicable confidence comes from, he thinks too highly of himself. I'm afraid that this heel will fall very hard today!

Wang Qingshan pondered in his heart, if there were few people, what would he say to ridicule Wu Mian after he went in?

But this can't be too straightforward, pointing at the nose and scolding the street, that's what the shrew does. But it can't be too subtle, otherwise Wu Mian can't understand this dog's pretend.

Hey, even if you hold an academic conference by yourself, you don't dare to hold it so big, at least one month's notice. At least 10 percent of the directors of cardiothoracic surgery in China have studied under him, just like Li Zhong.

That's it, I don't dare to hold it up, why is Wu Mian? Wang Qingshan thought in his heart.

Thinking of the empty venue, Wang Qingshan was very happy. Even if a few people came and saw them come in, they would stand up to greet them. When Wu Mian stands on it and talks about things, I'm afraid it will be very embarrassing.

All this is in Wang Qingshan's calculations, and he is ready to give Wu Mian a good look, so that this dog-day kid knows who is the boss.

Walking to the door of the conference room, Zheng Kaixuan took two quick steps, holding his hand on the doorknob.

Wang Qingshan stopped, straightened his suit and tie, and Zheng Kaixuan opened the door. Wang Qingshan saw that in the conference room, Wu Mian was standing on the podium, pointing at a PPT with a laser pointer, and saying something.

Striding in, Wang Qingshan looked at Wu Mian and coughed deliberately.

The other person was tall and loud, his voice was like a bell, and the coughing voice was not suppressed by Wu Mian's microphone voice, which successfully attracted the attention of the people around him.

Wang Qingshan could feel a lot of eyes projected on him, and he was a little proud and a little surprised.

I was surprised that the number of people seemed to be more than I expected, the conference room could seat about 100 people, although there were some empty seats, but there were not many, and the conference room was basically full.

Proudly...... didn't wait for him to be proud, and suddenly Wang Qingshan felt that something was wrong.

Turning his head to look around, Wang Qingshan was stunned to find that there were only a dozen doctors in China, and it was indeed like what he imagined, in the case of non-weekends and holidays, domestic directors had to have surgeries to do, and not so many people had time to listen to lectures.

But others...... They are all foreigners, foreigners of all kinds.

Judging from the superficial characteristics, Wang Qingshan could at least tell that people from four or five countries were sitting quietly below listening to Wu Mian's lectures.

"......" Wang Qingshan's heart tightened, and the pride in his heart was gone.

Isn't it too unqualified for him to come late and disturb the foreign doctors attending the class? Wang Qingshan hurriedly did self-examination, the gloom on his face disappeared, he hunched his waist, and found a place in the corner to sit down.

And Wu Mian, who was standing on the podium, seemed to have not seen Wang Qingshan come in at all, and continued to explain the operation intently.

"Previously, we fell into the misconception that minimally invasive surgery for the heart can only be done through interventional surgery, such as the closure of patent ductus arteriosus......"

Wu Mian stood on the podium and said loudly, Wang Qingshan pouted. It's all the basics, and he really thinks he's lecturing to medical students?

"Improving the technique, in fact, is very simple. A 2-3 cm surgical incision is made above the apex of the heart and opened directly to face the heart. In this way, the surgical path is shorter, and many difficulties can be easily solved. ”

"It's like this. ”

As he spoke, the laser pointer in Wu Mian's hand pointed to the projection of the PPT and said, "Here, the surgeon makes an arc-shaped incision from the rib space on the right side, passes through the skin → fat→ muscles→ pericardium→ left atrial wall layer by layer, and directly reaches the left atrium for mitral valve modification." ”

"The advantages are that the sternum is not damaged, the wound is significantly reduced, the skin surface incision is shortened to about 2-3 cm, and the wound is more likely to heal parallel to the skin texture. When you are not proficient in surgery, you can enlarge the incision to about 5cm, which is no problem. ”

"The disadvantage is that the surgical field is not as good as the median incision, the operation is more difficult, and only a relatively simple lesion can be treated;

"The surgeon cuts through the skin → fat → muscle layer by layer→ pericardium → the left ventricle, inserts a thin tube through the apex of the left ventricle, and feeds a mitral valve clamp through the thin tube. It should be noted here that ValveClamp is independently developed by Huaxia MicroPort. ”
