Wang Qingshan doesn''t know how others evaluate himself. Even if he knows, he doesn''t care at all. In his opinion, people with black hair and yellow skin in China are fools.


    Back in the imperial capital, Wang Qingshan took Zheng Kaixuan to Pengcheng for a night''s rest.


    Although there was no preparation, Huaxia minimally invasive sent a car to pick up Wang Qingshan and his party after receiving the news.


    In any case, he is an outstanding figure in cardiothoracic surgery in China and cannot be neglected. This is especially true for commercial companies such as Huaxia minimally invasive.


    After staying in the hotel, he slept heavily. After eating early the next morning, Wang Qingshan didn''t go directly to the conference hall, but went back to his room and waited for a long time.


    At 9:10, after the start of the meeting, Wang Qingshan took Zheng Kaixuan downstairs and swaggered to the conference hall. Wang Qingshan was extremely dissatisfied because he was not accompanied by staff. His face seemed to have been gloomy since he went to bajingzi.


    At this time, his face was very gloomy.


    "Xiao Zheng, can you tell me if Wu Mian''s goods are not worth counting?" Wang Qingshan said as he walked.


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


    "Once in a while, if you succeed in an operation, you really think you''re awesome? You really think you can crush the whole world? Bullshit! What''s on his mind? This is." Wang Qingshan didn''t seem to want Zheng Kaixuan''s answer, so he said to himself, "How long has LANCO studied this technology? More than ten years! You have also used LANCO''s consumables, which are much easier to use than domestic consumables. Why can''t you know yourself clearly?"


    "Li Zhong, I''ve been thinking for two days. I seem to have some impression. It''s the poor boy from the north, a dark and strong doctor. I think it''s more suitable for him to go to orthopedic department to resist thigh, but he can''t do cardiothoracic surgery."


    Listening to Wang Qingshan talking all the way, Zheng Kaixuan kept silent.


    Wang Qingshan strode to the conference hall while talking to himself.


    After years of experience, Wang Qingshan is sure that there will not be many people. After all, domestic doctors are very busy. When they suddenly notice that they want to have a meeting, they rush over. Isn''t this bullshit.


    Wu Mian really thinks of himself as the leader of the Wulin alliance? No one dares not to obey orders. I really don''t know where his inexplicable confidence comes from. He thinks too highly of himself. I''m afraid he will fall very hard today!


    Wang Qingshan thought to himself that if there were few people, what would he say to ridicule Wu Mian when he went in? He must say something to beat his arrogance.


    But this can''t be too straightforward, pointing to the nose and swearing. It''s a bitch''s job. But it can''t be too implicit, otherwise Wu Mian can''t understand what to do.


    Hey, even if you hold an academic meeting, you don''t dare to be so big. You should inform me at least one month in advance. What''s your status? At least 10% of the directors of cardiothoracic surgery in China have studied under their hands, just like Li Zhong.


    That''s it. I don''t dare to ask big. Why should Wu Mian?! Wang Qingshan thought to himself.


    Wang Qingshan was very happy at the thought that the venue was empty. Even if a few people came and saw themselves coming in, they would stand up to welcome them. At that time, Wu Mian would be very embarrassed to stand on it and talk.


    All this is in Wang Qingshan''s calculation. He is going to give Wu Mian a good look and let the dog day boy know who is the boss.


    Walking to the door of the conference room, Zheng Kaixuan took two steps and held his hand on the door handle.


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


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


    He was as loud as a bell. His cough was not suppressed by Wu Mian''s Mike, which successfully attracted the attention of the people around him.


    Wang Qingshan could feel a lot of eyes on himself. He was both proud and surprised.


    Surprisingly, the number of people seems to be more than expected. The conference room can seat about 100 people. Although there are some empty seats, there are not many. The conference room is basically full.


    He was proud... Before he was proud, Wang Qingshan suddenly felt something wrong.


    Looking around, Wang Qingshan was shocked to find that there were only a dozen doctors in China. It was really like what he imagined. In non weekends and holidays, domestic directors had surgery to do, and not so many people had time to attend classes.


    But others... Are foreigners, all kinds of foreigners.


    From the surface features, Wang Qingshan can at least see that people from four or five countries sit quietly below to listen to Wu Mian''s lecture.


    "..." Wang Qingshan was so worried that his pride disappeared.


    Wang Qingshan hurriedly made a self-examination. The gloom on his face disappeared. He arched his waist and sat down in the corner.


    Standing on the podium, Wu Mian seemed not to see Wang Qingshan come in at all, and continued to explain the operation attentively.


    "Before, we fell into a misunderstanding that minimally invasive heart surgery can only be completed through interventional surgery, such as the closure of patent ductus arteriosus..."


    Wu Mian stood on the platform and said in a loud voice. Wang Qingshan turned his mouth. These are the most basic things. Did he really think he was lecturing to medical students?


    "The improved operation is actually very simple. Take a 2-3cm surgical incision above the apical region and open it directly to the heart. In this way, the surgical path is shorter and the difficulties are solved."


    "Like this."


    Then, Wu Mian pointed the laser pen in his hand to the projection of the PPT and said, "here, the surgeon cut an arc incision from the right rib space, layer by layer through the skin → fat → muscle → pericardium → left atrial wall, and directly arrived at the left atrium for mitral valve repair."


    "The advantage is that the sternum is not damaged; the wound is significantly reduced, and the incision on the skin surface is shortened to about 2-3cm; and the wound is parallel to the skin texture, which is easier to heal. When the operation is not skilled, the incision can be expanded to about 5cm, which is no problem."


    "The disadvantage is that the surgical field of vision is not as good as the median incision, and the operation is more difficult. It can only deal with a relatively single and simple lesion; during the operation, single chamber ventilation is required to block the right lung, and only the left lung completes breathing, which has high requirements for lung function."


    "The surgeon cut the skin → fat → muscle → pericardium → left ventricle layer by layer, pierced a thin tube from the apex of the left ventricle, and sent it into the mitral valve clamp from the thin tube. Here, it is explained that valveclamp was independently developed by Huaxia minimally invasive."
