    Question?  He didn't dare.  He had misjudged the surgeon's mind once before.  It's no good that the surgeon didn't say thank you to the classmate right away.

    It can¡¯t be said that everyone can¡¯t figure out Xie¡¯s brain.  At least there is a person like Pan Shihua here who is best at exploring Xie's thinking.

    "I understand. What Yingying means is that if you pull two close points, the tension may explode, but they are the same plane after all. You can close them first to reduce the tension of the two close points.  Pull again." Classmate Pan Shihua said.

    ¡°It¡¯s over, after classmate Pan finished speaking, a lot of people found that they couldn¡¯t understand what it meant.

    Seeing this, Xie Wanying hurriedly added a few words to classmate Pan: "Surgical suturing is like sewing technology. You have to convert three-dimensional organs into a two-dimensional plane to suture. All suture planes can be simply regarded as cloth with a tension surface. Three-dimensional organs  The surface is just a piece of cloth wrapped around in a circle.¡±

    oh.  The medical students who were observing suddenly realized how big the gap was between themselves and their top students.

    Now we need to use all the tension of the "cloth" on the surface of the heart to reduce the tension at the two middle points.  How to do it can be done by pulling on the two fulcrums of the superior and inferior vena cava.  The superior vena cava will completely block the operating sight. Select the inferior vena cava as the focus point and sew a stitch to see how far it can be pulled to make up for this incomplete gap.

    You should pay special attention when pulling. What should you pay attention to?  It is also important to pay special attention to the maximum tension that the suture can withstand.  This corresponds to the suture tension principle that I spent time talking about earlier.  Otherwise, even if the tension is leveled out in this way, even if the anastomosis can be sutured upward, the pressure will be extremely high due to the entrance and exit blood vessels of the heart.  Once the suture tension limit is exceeded, the suture will easily collapse later.

    From this point of view, Xie¡¯s suggestion actually focuses on the calculation of the maximum tension of the two sutures in the latter sentence.

    How to test?  When calculating the maximum value in mathematics, physics and chemistry problems, should we directly give the maximum value?  No, I will give you the basic data to calculate.  The same principle applies here. There is no need to really pull the thread apart to check the limit value. You only need to measure other data to calculate the upper limit of the tension of the two sutures and find the upper limit that is suitable for the surgical technique.

    It makes sense in theory, it seems very simple, but people around you can actually understand half of it, which is great.  Next, let them do the math, and everyone decided that they would become a ball of brain muddle.

    Classmate Wei shouted in his heart to surrender, it was too difficult and he would rather continue to be a poor student.

    Doctor Cheng Yuchen was dumbfounded: As a senior, he could not use any adjectives to describe this student's brain, because he could not imagine how this person's brain worked.

    Other medical students standing in the operating room, including Dai Nanhui, could only guess: This classmate probably wanted to guess a random mathematical answer.

    Duan Sanbao thought that his two elder cousins ??both liked to touch Xie¡¯s brain, which meant that the Cao family¡¯s elders never thought that Xie would make random guesses.  Many of the Cao family members are good at neurosurgery and have a good understanding of how high the human brain can reach.

    Not surprisingly, the small whirlpools in Cao Zhao's dark eyes shone brightly under the magnifying glass during surgery. He looked at the student's brain and said, "You can sew this stitch faster." After that, he instructed the nurse to give her the instrument.

    Others gasped when they saw it: Boss, are you slapping yourself in the face by asking Xie directly for verification?

    This man is either a god or a devil.  Classmates Wei and Pan checked again in their minds.
