Question? He didn't dare. He had guessed wrongly about the surgeon's mind once before. Now the surgeon still didn't say thank you to his classmate immediately.
It cannot be said that everyone can't figure out Xie's brain. At least there is a person like Pan Shihua who is best at exploring Xie's thinking here.
"I understand. What Yingying means is that if you forcefully pull two close points apart, the tension may explode, but they are the same plane after all. You can close them together first to reduce the tension at 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 didn't understand what he 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 the 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. To do this, you can pull on the two fulcrums of the superior and inferior vena cava. The superior vena cava will completely block the operating sight.
, choose the inferior vena cava as the focus point, sew a stitch and pull it to see how far it can be pulled to make up for the gap.
When pulling, you need to pay special attention. What should you pay attention to? You also need 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, if the tension is evened out in this way, even the anastomosis will be
It can be sutured upward, but the pressure here is extremely high because of the entrance and exit blood vessels of the heart. Once the tension limit of the suture 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 measure? When calculating the maximum value in mathematics, physics and chemistry problems, do you need to give the maximum value directly? No, we give you the basic data to calculate. The same principle applies here. Needless to say, you really have to pull the line 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.
Theoretically it makes sense, it seems to be very simple, and it is good if the people around you can actually understand half of it. Then let them do the math, and everyone thinks that they will become a ball of brain muddle.
Student Wei cried out 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 when they didn't expect it: 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 never thought that Xie would guess and talk nonsense. Many of the Cao family members are good at neurosurgery, and how much knowledge can be gained about the human brain?
A highly cognitive one.
Not surprisingly, the small whirlpools in Cao Zhao's dark eyes shone brightly under the surgical magnifying glass. 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 instruments.
Others gasped when they saw it: Boss, are you slapping yourself in the face by directly asking Xie to verify?
This man is either a god or a devil. Classmates Wei and Pan checked again in their minds.
