Chapter 428 Serious Professor Liang
The difficulty of this case is that the deformity has not been finalized and is in dynamic change.

Ordinary osteotomy orthopedics only targets static deformities and cannot cope with future growth and development.

The osteotomy itself is disruptive and interferes with the development of the spine, which complicates matters.

If an external fixator can be used for orthopedic correction, all difficulties will be solved, but the design of this external fixator is not easy.

There is a huge distance between ideas becoming reality, especially in the medical field.

After returning to the doctor's office from the ward, Professor Liang sat down and asked, "What stage is your external fixator at?"

Medical devices and drugs have strict procedures from research and development to application. Compared with drugs, medical devices are much more relaxed.

"The design is mature, and now we are going to conduct animal experiments. We need a batch of juvenile monkey models with scoliosis deformity. We are contacting to buy experimental monkeys to find a way to make scoliosis models. The whole process will take a long time. We will let them The child will go back first, wait for a while, and then come." Yang Ping introduced the progress.

In fact, in the system space, Yang Ping completed the whole experiment process, but the system space is the system space, reality is reality, and the experiment must be repeated in reality.

For this child, Yang Ping has done countless research experiments in the system space, and has screened various technologies, such as epiphyseal blocking technology.

This technique selects some points on the epiphysis of the spine and blocks them to make it grow slowly, resulting in unbalanced growth and development of the various parts of the spine.

Scoliotic deformity is the result of growth and development imbalance, if the epiphyseal block is used to counteract this imbalance.

In theory, spinal deformities correct themselves during growth and development.

A simple curved model, where the convex side grows slower and the concave side grows faster, so that the two sides are unbalanced, and eventually, the bend straightens.

This hockey stick theory is also the theoretical basis for the application of epiphyseal block in orthopedic surgery.

This technique is currently used in orthopedics for simple deformities of children's joints.

For example, children's real X-shaped legs or O-shaped legs can use the epiphyses and growth plates at both ends of children's long bones, and the ideal orthopedic effect can be achieved through simple surgery to control the growth plates.

In this way, the trauma is small, the recovery is fast, and there is no need to break the bone; for adults, X-shaped or O-shaped leg surgery can only be performed by osteotomy.

This operation uses the principle of epiphyseal block, called temporary semi-epiphyseal block. Temporary means that the block produced by this operation has a time limit and is not permanent. To achieve the goal, the block must be canceled and the epiphysis Restoration of growth; semi-epiphyseal is when part of the epiphysis stops growing while the other part continues to grow.

Like a simple bending stick, for the knee joint, if the inner part is controlled, the outer part keeps growing, the inner side grows slowly, and the outer side grows faster, and the knee joint is bent inward, then the normal knee joint will become O-shaped, and vice versa Then it becomes X type.

If it is originally an O-shaped leg, the outer side is blocked, the inner side grows faster, the knee joint bends outward during the growth process, and the deformity is corrected, and the X-leg is just the opposite.

This technique works well for X or O-shaped legs at the knee joint because the deformity is as simple as bending inwards or outwards.

However, the spine is three-dimensional, and it is very difficult to find the control point. If you find the control point, the degree of blockage cannot be grasped. The result of this is that the spine changes from one deformity to another.

So Yang Ping gave up the application of epiphyseal block and chose Ilizarov's tension stress theory instead.

Yang Ping completed a large number of experiments in the system space and consumed a lot of points. Finally, he will obtain valuable data and improve the external fixator to a clinically practical level.

Yang Ping asked Song Zimo to take out the mobile hard disk and connect it to the computer, which contained detailed drawings of the design of the external fixation frame.

When Professor Liang heard that it was a detailed drawing, he waved his hand: "Just know that we have reached the stage of animal experiments, and I will not read the details."

Professor Liang is well-known in the academic circle for this. He did not play a key role in publishing the papers of his students. He will never be the first author. He will never add a name to those who have no real participation. Never plunder the scientific research achievements of students.

He also constantly reminded students that no matter how other people's achievements are obtained, when writing articles or citing them in public, they must indicate the source and indicate that they are citations.

As a member of the National Committee of the Chinese People's Political Consultative Conference, Professor Liang has a proposal to increase the punishment of intellectual property violations. If there is no punishment, the offenders are unscrupulous. Anyway, if you plagiarize your work, I will gain both fame and fortune. Even if you sue, I will pay you tens of thousands. matter, who is afraid of whom.This greatly kills the enthusiasm of the real original creators.

Yang Ping did not expect Professor Liang to be so serious about this matter, and immediately explained: "This is just a blueprint of the equipment, and it is only a part of the technology, which can be made public."

Since Yang Ping said that it can be made public, it's okay to have a look, Professor Liang nodded in agreement.

The drawings in the mobile hard disk are opened, very detailed, decomposed pictures, three-dimensional pictures, pictures of each part, and group pictures showing application principles.

Yang Ping explained the principle and some details of this set of equipment to the pictures.

This set of equipment is very mature from the theoretical basis to the mechanical design, and can be used in clinical experiments. Now there is only one animal experiment data to support it.

Yang Ping's scientific research talent is so high?An innovation can be so mature that it can be applied clinically immediately after animal experiments.

It takes several years for a complete team to go from idea to blueprint for this kind of thing, and it may not be successful.

Now that he has taken it out, he is already mature. Could it be that he studies this just after graduation.

In fact, Yang Ping didn't know how many times he failed in the system space before he succeeded. Millions of points were consumed. If he failed again, he would not dare to consume points to continue.

Professor Liang is not good at asking the bottom line, anyway, no matter what the reason is, the things are here, so he said: "Your equipment is very mature, and the animal experiment is missing. We have a cooperative laboratory with the Chinese University of Hong Kong. Among them is Using experimental monkeys as models to study scoliosis, this laboratory is located in Guilin, Guangxi, and has been in operation for three years, accumulating a lot of data, and now the data is open to you, Director Hu, how many baby monkeys are there in the existing model?"

"These experimental monkeys are all cynomolgus monkeys, so they should be very suitable for research. How old are the monkeys? Under six years old?" Professor Liang asked.

"Yes, that's great. I just want to take some time to go to Guangxi to see the experimental monkey base over there." Yang Ping knows that their laboratory is located in Guilin because it is convenient to obtain experimental monkeys. Guangxi has the largest laboratory in the country. Experimental monkey breeding base.

"I'll implement it later!" Director Hu wrote down Professor Liang's words.

Professor Liang was a little displeased: "Don't ask later, just now, for a few words, ask now."

"Okay, I'll be right away!" Director Hu was used to Professor Liang's style, but he was still a little embarrassed.

In front of everyone, Director Hu made a phone call to inquire about the situation of the Guilin laboratory. The personnel in the laboratory there, except for a few daily management staff, are sent by Xiehe and the Chinese University of Hong Kong in rotation.

For the scoliosis model of the experimental monkey, it is necessary to buy the experimental monkey and then make the scoliosis model by yourself, which requires a process. Therefore, if the experiment is launched soon, it is necessary to know whether the stock is enough.

"Yes! 34 baby monkeys! They have all completed the health quarantine and immunization plan, and can be put into the experiment at any time." Director Hu replied.

"34, that's enough!" Professor Liang did some calculations.

"All gather together to do experiments on Dr. Yang's subject. Xiao Yang, if you agree, we can cooperate on this point. We can help you complete your animal experiments. What do you think? We don't name the papers, and the first batch of experiments will be done at that time." Cases, let us give priority to observation." Professor Liang did not want to take advantage of young people, but sincerely wanted to use his own resources to help Yang Ping.

"Then thank you Professor Liang." Yang Ping agreed.

In fact, it is not an exaggeration to add a name, after all, he helped to complete the animal experiments, but Professor Liang's style is like this, so Yang Ping didn't mention it, and went along with him.

"Xiao Yang, you send over the detailed experiment plan, they will complete the animal experiments, and Director Hu will be in charge of the liaison on this project." Professor Liang said a few words, and the cooperation on this project was confirmed.

Cooperation on topics can drive everyone to make progress together, and more importantly, they don't work behind closed doors.

This is the same as enterprise production, master the core technology, and let upstream and downstream cooperative enterprises do other things, and do everything by yourself, which will reduce efficiency.

After visiting the ward and visiting the operating room, Professor Liang and Yang Ping had a lot to say, which prevented Director Han and Director Xia from getting in the conversation, and they just shook their heads and sighed.

In the evening, we had dinner together, accompanied by Professor Su, Dean Xia, Director Han, Director Tian, ​​several directors of the Department of Orthopedics, all the doctors of the Department of General Orthopedics, and the Xiehe training group.

When Professor Su saw Yang Ping, he was very kind. If it wasn't for the occasion, he would have pulled Yang Ping to sit beside him. Since Yang Ping came back from the United States, Professor Su has been looking for a chance to meet Yang Ping.

This time at the Golden Knife Award, Yang Ping won the championship, Su Yixuan won the Best Device Nurse, and both of them won awards. Professor Su and his wife often talked about this and laughed from ear to ear.

At the same time, the two couples were also anxious, why didn't this girl tell her family about her love affair, and why didn't she bring Yang Ping to meet her parents. They tried to urge her several times, but held back.

This time, Professor Su has also heard about the robbing war between Xiehe and 301. He has been paying attention to the trend, and he doesn't know which hospital Yang Ping will go to. pondering.

If it is said that the near-water towers come first, Nandu Fuyi has an advantage, but Professor Su is like a bright mirror in his heart.

Yang Ping is currently doing well in Sanbo, and there is no need to move places. Even if he moves, he really goes to Xiehe or 301, which is better than Nandu Fuyi.

Therefore, Professor Su is neither impatient nor impetuous. He is as stable as Mount Tai. He has already planned how to do it. He knows that neither Yang Ping nor his daughter want to develop under his wings, otherwise Su Yixuan would not be in Sanbo. Hospital work.

"Professor Su!" Yang Ping had already picked up the cup.

During the green dinner, everyone drank drinks, Professor Su hurriedly toasted: "Xiao Yang, this time the Golden Knife Award is very good, especially the one with scoliosis, I was terrified to see it."

"Professor Su's award, my method is a little improvement on the basis of my predecessors." Yang Ping should be humble in front of his father-in-law.

This child, Professor Su's heart is full of joy. He is humble when he should be humble, and proud when he should be proud. He likes this character.

"When will I come to Fu Yi to take a look, Nan Chen always mentions you." Professor Su put down his glass.

"Xiao Yang still has friendship with your young master?" Professor Liang was very surprised, but also puzzled, this Su Qingyun is also famous for his talent, why didn't he do anything to Yang Ping.

Su Nanchen graduated from Peking Union Medical College, and all clinical courses were completed in Union Medical College Hospital. Professor Liang is naturally familiar with it.

Looking at Professor Liang's puzzled eyes, Director Han understood, just smiled, Su Qingyun was so anxious, no matter where he went, he had to recognize him as the father-in-law.
