Questioning? He didn't dare. He guessed wrongly that the main surgeon had once. The main surgeon didn't immediately say thank you for your classmates.

It cannot be said that everyone will definitely not touch the mind of Xie. At least there is a person like Pan Shihua who is the best at fumble on Xie’s thinking.

"I understand. Yingying means that if two close points are pulled, the tension will probably explode, but it is the same plane after all. You can close it first and reduce the tension of these two close points before pulling it." Student 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 helped Pan to add two sentences: "Surgery suture is like sewing technology, and you have to transform three-dimensional organs into two-dimensional planes to stitch. All suture planes can be simply regarded as cloth with a tension surface. The surface of the three-dimensional organ is just a piece of cloth wrapped around it."

Oh. The medical student who was listening suddenly realized how big the gap between himself and the top student was.

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? You can pull the two fulcrums of the upper and lower vena cava. The upper vena cava will completely obstruct the operating line of sight. Choose the inferior vena cava to stitch the focus point and see how much it can be pulled to make up for this inadequate gap.

Pay special attention when pulling, what should I 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 mentioned earlier. Otherwise, if the tension is flattened in this way, even if the anastomosis can be sutured, the pressure here is very high. Once the suture tension limit exceeds the suture tension limit, the suture will easily collapse later.

In this way, the suggestion made by Student Xie is actually focused on the later sentence calculating the maximum tension of the two sutures.

How to measure it? In mathematics, physics, chemistry and mathematics problems, should I calculate the maximum value directly? No, I will calculate the basic data for you. The same is true here, it goes without saying that I really pulled the line and checked the limit value. Just measure other data to calculate the upper tension limit of the two sutures and find the upper limit value suitable for the surgery.

In theory, it seems very simple. It is good for the people around you to understand half of it. Let them calculate it, and everyone will think they will become a mess of brain.

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

Dr. Cheng Yuchen was stunned: He, the senior, could not use any adjectives to describe the student's brain, because he could not imagine how this person's brain turned.

Other medical students standing in the operating room, including Dai Nanhui, could only guess: this student probably wanted to take a mathematical answer.

Duan Sanbao thought that his two cousins ​​liked to touch Xie's brains very much, which shows that the Cao family's boss never thought that Xie would guess and talk randomly. Many of the Cao family are good at neurosurgery, and they have a good understanding of what height the human brain can reach.

Not surprisingly, the small vortex in Mo's eyes under the magnifying glass of Cao Zhao's surgery was shining brightly. He looked at the student's mind and said, "You'll stitch this stitch faster." After that, he instructed the nurse to give her the equipment.

Others took a breath when they saw this: Boss is asking Student Xie to verify whether he was slapping himself in the face?
