Returning to ’90s, She Became Famous in Major Surgical Fields

   Chapter 2558 [2558] The point is here

   Question? He dared not. He had guessed the chief knife's brain wrong once before. The chief swordsman did not immediately say thank you to classmates now.

   It can’t be said that everyone can’t touch Xie’s brain. At least one student like Pan Shihua, who is best at exploring the thinking of classmate Xie, is here.

"I understand. What Yingying means is that if you deadlift two close points, the tension will explode, but it is the same plane after all. You can close it first to reduce the tension between the two close points. Pull again." Pan Shihua said.

After   , this classmate Pan finished speaking, and a lot of people found that they couldn't understand what it meant.

Seeing this, Xie Wanying hurriedly added another sentence to Pan: "Surgical stitching is like sewing technology, you have to convert three-dimensional organs into two-dimensional planes to sew them. All suture planes can be simply viewed as cloths with tension surfaces. Three-dimensional organs are The surface is nothing but a piece of cloth wrapped around it."

Oh. The medical students who were listening in came to a sudden realization, and suddenly realized how big the gap was between themselves and the academic masters.

   Now we need to use all the tension of the "cloth" on the surface of the heart to reduce the tension of the two middle points. How to do it, you can pull and pull on the two fulcrums of the superior and inferior vena cava. The superior vena cava will completely obstruct the sight of the operation. Select the inferior vena cava as the focal point to sew a stitch and pull it to see how much it can be pulled to make up the gap.

   Pay special attention when pulling, what do you pay attention to? Also pay special attention to the maximum tension the suture can withstand. This corresponds to the principle of suture tension that I spent time talking about earlier. Otherwise, the tension will be flattened out, even if the anastomosis can be sutured on top of each other, but here are the blood vessels at the entrances and exits of the heart, and the pressure is extremely high. Once the suture tension limit is exceeded, the suture can easily collapse in the future.

  In this way, Xie's suggestion actually focused on the latter sentence to measure the maximum tension of the two sutures.

  How to measure? Is it necessary to directly give the maximum value when calculating the maximum value in a mathematical problem? No, give the basic data for you to calculate. The same is true here. Needless to say, the thread is really pulled apart to check the limit value. It is only necessary to measure other data to calculate the upper limit of the tension of the two sutures and find the upper limit of the suitable technique for surgery.

   It makes sense in theory, it seems to be very simple, and people around you can actually understand half of it. Then let them do the math, and everyone thinks they're going to be a mess.

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

   Dr. Cheng Yuchen was dumbfounded: For this student's brain, his predecessor cannot use any adjectives to describe it, because he can't think of how this person's brain turns.

  The other medical students standing in the operating room, including Dai Nanhui, could only guess when he didn't expect it: This classmate probably wanted to bet on a math answer.

   Duan Sanbao thought that both of his two big cousins ​​liked to touch the brain of Xie, indicating that the Cao family never thought that Xie would guess and talk nonsense. Many of the Cao family members are good at neurosurgery, and they have a good understanding of how high the human brain can be.

  Not surprisingly, the small vortex in Cao Zhao's surgical magnifying glass was shining brightly. He looked at the student's brain and said, "You can sew this stitch faster." After speaking, he instructed the nurse to give her the equipment.

  Other people took a breath when they saw it: Big Brother, is this directly asking Xie to verify whether he is slapped in the face?

   This man is not a fairy but a devil. Wei and Pan checked again in their hearts.
