Chapter 322 Jigsaw Puzzle
"There is also a team at Southern Metropolis University of Technology that is researching brain-computer interface technology. I don't know how it is going. The members in charge of EEG signal research often ask me questions and invite me to participate." burst out again.

"Xu Zhiliang, you find them. If possible, we can cooperate. We will discuss this separately after the meeting."

Yang Ping already has a clear plan in mind. He wants to use the research of brain-computer interface to develop artificial transmission of nerve signals, and finally overcome the recovery of spinal cord injury.

In the system space, he has almost infinite time to read. This kind of massive reading makes Yang Ping's breadth and depth of professional skills beyond the reach of ordinary people.

"I can also help to contact ATR." Takahashi always wanted to do something.

He always hopes to do something meaningful, like casting a certificate of honor, to establish a stronger relationship with Yang Ping.

"Well, Takahashi, do you know more about their progress and technical route?"

Yang Ping appreciates Takahashi's transformation this time. This kind of learning spirit corresponds to an old Chinese saying that nothing is difficult in the world, as long as there is a heart.

After free discussion, everyone’s opinions were relatively consistent and clear. Yu Shuilian’s postoperative treatment is divided into three stages. The first step is to try to avoid infection and organ failure and pass the dangerous period; the second step is to reconstruct the anus and Urethra, to restore the function of defecation and urination; 3. The third step is to restore the ability to walk upright with the help of prostheses as much as possible. The task of each step is very arduous.

Yang Ping paused, and summarized what he just said: "Everyone's opinions are relatively clear. Our most urgent problem at present is to help patients successfully overcome the difficulties of infection and organ failure; then rebuild the anus and urethra, restore physiological excretion ability; finally restore The patient's ability to walk upright; during the whole process, psychological counseling should be provided to establish the patient's optimistic and positive mental state."

Song Zimo used a notebook to keep meeting minutes, and all of these had to be written into the course record, with a dedicated page for case discussions.

As for Dr. Yang, Dr. Yang hasn't expressed his opinion yet. Everyone is looking forward to Yang Ping's speech, especially those students, who are eagerly waiting for Yang Ping to speak.

Yang Ping knew that everyone was waiting, so he sorted it out a bit and said: "The patient's bladder is still there, and the sphincter function and urination reflex are preserved, and urination can be controlled, and urinary incontinence will not occur in the future; however, the anus, rectum and sigmoid colon are all The anus has been resected and the anus has been reconstructed. The biggest problem is before us, how to rebuild the original anal sphincter function and defecation reflex to avoid fecal incontinence.

Takahashi originally thought that the second-stage surgery would stay at the level of plastic surgery at most, just to establish excretory channels. Unexpectedly, Yang Ping would also rebuild the anal sphincter function and defecation reflex in pursuit of simulating normal functions.

Yes, why didn't I think of this, Takahashi immediately took out his notebook and recorded that Dr. Yang was far superior to himself in terms of surgical skills and surgical thinking. After only a few days, he felt that he had gained a lot.

"This is a brand new topic. The anal sphincter is the orbicularis muscle. There are very few parts of the human body that have the orbicularis muscle. Around the eyes, around the lips, and the neck of the bladder, these are all orbicularis muscles. It is impossible to use these as donors for reconstruction. Anal, right?" Takahashi relaxed a lot, and spoke freely like a young student.

"How does the mouth open and close? How do the eyes open and close? How does the bladder control urination? Any of them can't be used to replace the anal sphincter?"

Zhang Lin felt that this was a meeting of gods, and he couldn't get in. He was completely marginalized, and he had to say a few words whenever he got a chance.

"Is it possible to take a part as a donor? After all, muscle fibers and muscle strength have plasticity. Even if a part is cut away, can it be restored to its original shape and muscle strength through training?"

Xiao Wu finally caught up. With a group of talented people, he was most afraid of this kind of discussion, so he just chatted and chatted. From "Nature" to "Science", he was dizzy from shaking his head. It was hard to catch Hold the tail a little, and people flick it lightly, but the hair is not caught.

The eyes of the brothers and sisters in distress met, and there was an instant sympathy: Thank God, the tail of the discussion was caught.

"Not only is the replacement material for the sphincter muscle a problem, but also the reconstruction of the anal defecation reflex. In order to rebuild the bladder reflex for patients with spinal cord injuries, Professor Xiao Chuanguo of Wuhan Tongji Hospital created the Xiao's reflex arc, which has achieved certain success. We can learn from it." Song Zimo was silent for a while, then returned to the center of the discussion.

"This is definitely a difficult problem. How to reconstruct it is not discussed at this meeting. This is a homework for everyone. I hope that after two weeks, each person will come up with a specific operation plan. If you have no opinion, today's Is this the end of the case discussion?"

Everyone agrees that if the discussion continues, no specific plan will be produced even tomorrow.

Takahashi is very interested in this assignment. This is a case discussion in the department, and the assigned assignment is actually such a profound problem.

This kind of surgery, even if there are talents and plans to follow, the difficulty of the surgery itself is very high, requiring a combination of knowledge in orthopedic surgery, reconstructive surgery, plastic surgery, microsurgery, neurosurgery, gastrointestinal surgery, anorectal surgery, etc. to perform such an operation.

"Dr. Yang, can you tell us about Yu Shuilian's surgery, how your garbled code surgery was done, and why it was arranged this way?" Takahashi was afraid that Yang Ping would end the meeting.

Yang Ping told Gaoqiao that this operation method has no learning value, because it is too difficult for others to copy.

Takahashi also knew in his heart that he couldn't do it, but he didn't want to give up after all, even if he couldn't learn it, he still had to figure out the principle.

There are five large jigsaw puzzles on the table, which are the teaching aids prepared by Xiao Wu. Yang Ping got up, tore off the film of the five jigsaw puzzles, pulled out all the pieces that had been put together, poured them on the table, and rubbed them into a mess.

The background colors of these five puzzles are different, namely red, yellow, blue, green, and purple, but now they are all mixed together and become a messy pile.

"Everyone, please see clearly, I will demonstrate the method of conventional surgery first."

Yang Ping didn't explain too much, the movement in his hands was very fast, he sorted the pieces according to the background color first, picked out the same color and put them in a pile, and then in the order of red, yellow, blue, green, purple, piece by piece Each piece of the puzzle is assembled in the order of left, right, top, bottom.

As the pieces were pressed in one by one, soon, the five pieces of the puzzle were assembled in sequence, and everyone was amazed at his memory and puzzle ability.

Yang Ping has reshuffled the jigsaw puzzles, mixed them together, and made them into a pile, all kinds of colors mixed together, making a mess.

"Now, I will demonstrate another surgical method, which is the garbled code surgery you mentioned."

This time, Yang Ping did not classify the small pieces, but took them from the pile of pieces, no matter which piece of the puzzle, no matter where it was, put it directly in the original position.

Sometimes this piece of the puzzle is pasted, sometimes that piece of the puzzle is pasted, sometimes it is the center of the puzzle, and sometimes it is the edge of the puzzle. There is no order or structure, whichever piece is convenient, take that piece.

Slowly, there are fewer and fewer pieces on the table, and the picture of the puzzle is becoming more and more complete. When the last piece is pressed in, all the pieces of the puzzle are assembled, and one piece is not bad.

The language explanation was too strenuous, so Yang Ping used a puzzle to demonstrate his garbled operation in an easy-to-understand manner.

It's just that everyone looked like magic, and they were not ready yet. The jigsaw puzzle has been successfully put together twice with two methods.

Song Zimo, Xu Zhiliang and Gao Qiao all stood up and picked up a few puzzle pieces on the table to see that there were no mistakes at all.

Even the film of these jigsaw puzzles has just been torn apart, and Yang Ping only came into contact with it temporarily, so it is impossible to write it down in advance, and there is no need to play tricks on purpose for a demonstration.

What a powerful brain, what a powerful overall planning ability, is this a human brain?
The second jigsaw puzzle took much less time than the first jigsaw puzzle. If someone else puts it together in the second way, they will definitely fall into chaos.

Gao Qiao understood, this is why Yang Ping told him not to learn, because others couldn't do it at all.

The jigsaw puzzles were scattered on the conference table, and Takahashi kept fiddling with them, still wanting more.

Yu Shuilian's operation is a piece of the puzzle, and it is an emergency rescue operation. There is no time to familiarize yourself with the operation, so it is like a few brand-new jigsaw puzzles in front of you. There is no time to think, just start to put together, even the opportunity to hesitate nothing.

In this case, no one will choose the second method, as long as normal people will definitely choose the first method.

"Can you?" Xu Zhiliang asked Song Zimo.

Song Zimo shook his head: "Yes, but the speed will be slower than the first method, and it will take a certain amount of time to think and search."

"Me too. If it's a jigsaw puzzle competition, I dare not use the second method." Xu Zhiliang was convinced.

Takahashi fiddled with the jigsaw puzzle as if looking at a magic prop: "Mr. Wu, did you buy it new?"

Xiao Wu kneaded the film on the table into a ball: "The film is torn up freshly. Dr. Yang asked me to bring some puzzle pieces. I don't know what to do with them. I thought they were for Sisi to play with."

Takahashi gasped. At the academic conference, the Yang Ping who crushed him not only had the strongest hands, but also the strongest brain.

It is an honor to lose in his hands!
