Chapter 2558: The Focus Is Here

Question him? He didn’t dare. He’d already guessed wrong about the Chief Surgeon’s thinking once. The Chief Surgeon likewise hadn’t immediately said that Student Xie’s idea wouldn’t work.

You couldn’t say absolutely nobody could get a feel for Student Xie’s mind. At least there was a classmate like Pan Shihua here, the one best at figuring out how Student Xie thought.

"I get it. Yingying means, if you forcibly pull two close points together, the tension might blow up, but in the end it’s still the same continuous plane. You can first bring it together a bit, reduce the tension at those two close points, and then pull," Student Pan said.

Great. As soon as Student Pan finished, a whole bunch of people realized they now understood even less.

Seeing this, Xie Wanying hurriedly added a couple of lines to help Student Pan: "Surgical suturing is like sewing. For a three?dimensional organ you still have to convert it into a two?dimensional planar view to suture. All suture planes can be simply regarded as a piece of fabric with tension on the surface. The three?dimensional organ surface is basically a piece of cloth wrapped around."

Oh. The medical students sitting in on the case suddenly saw the light, and at the same time realized just how huge the gap was between them and a top student.

Right now the goal is to use all the tension of this ’cloth’ on the heart’s surface to lower the tension between those two points in the middle. How to do that? You can pull a bit using the two support points of the superior and inferior vena cava. The superior vena cava would completely block the operative field, so they choose the inferior vena cava as the fulcrum, place one stitch there and pull to see how much can be brought over to make up for that shortfall in approximation.

When you pull you need to pay special attention. To what? You likewise have to pay special attention to the maximum tension the suture can bear. This corresponds to the suture?tension principle they spent time talking about earlier. Otherwise, after you’ve flattened and redistributed the tension like this, even if the anastomosis edges can be matched and sutured, these are the cardiac inlets and outlets for the great vessels, with extremely high pressure. Once you exceed the suture’s tension limit, the suture can just as easily snap later on.

Looked at this way, the real focus of Student Xie’s suggestion actually lies in that last part about calculating the maximum tension of the two suture materials.

How do you calculate it? In math and physics problems, when you have to find a maximum value, do they just hand you the maximum? No, they give you basic data for you to calculate. Same logic here: you don’t literally have to pull the suture until it breaks to find the limit. You only need to measure some other data, use that to deduce the upper tension limit of the two sutures, and thereby find the upper technical limit suitable for the operation.

Theoretically it makes sense and sounds simple; if the people around actually understand half of it that’s already pretty good. Next step is making them do the math—everyone is convinced their brains are about to turn into a mushy puddle.

Student Wei mentally threw up his hands in surrender. Way too hard, way too hard. He’d rather keep being a poor student.

Doctor Cheng Yuchen stared, dumbfounded: faced with this student’s mind, as a senior he couldn’t find a single adjective to describe it, because he literally couldn’t imagine how this person’s brain was turning.

The other medical students standing in the OR, including Dai Nanhui, could only guess when they couldn’t figure it out: this classmate probably wants to randomly throw out some math answer.

Duan Sanbao thought of his two Boss cousins who both loved to poke at Student Xie’s thinking. That showed the Cao Family bosses never believed Student Xie would just randomly guess or talk nonsense. Lots of Cao Family people are good at neurosurgery and have a sense of what heights the human brain can reach.

No surprise, under the surgical loupes, the little whirlpool of dark light in Cao Zhao’s eyes flashed brilliantly as he looked toward this student’s head and said, "You suture this stitch. It’ll be faster." With that, he instructed the nurse to hand her the instruments.

The others saw this and sucked in a breath: the Boss is straight up letting Student Xie test whether she’s about to slap her own face?

This man isn’t a god, he’s a devil. Student Wei and Student Pan once more confirmed that in their hearts.
