The Godfather of Surgery

The difficulty of this case is that the deformity has not yet been finalized and is in dynamic change.

Ordinary osteotomy is only for static deformities and cannot cope with future growth and development.

Osteotomy itself can cause damage and interfere with the development of the spine, which complicates the problem.

If the external fixator can be used for orthopedics, all the difficulties will be solved, but the design of this external fixator is easier said than done.

Ideas become reality, and the distance between them is very long, especially in the field of medicine.

Returning to the doctor's office from the ward, Professor Liang sat down and asked, Which 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 looser.

The design is mature, and now we are ready to carry out animal experiments. We need a batch of juvenile monkey models with scoliosis deformity. We are contacting the purchase of experimental monkeys and looking for a method to make a scoliosis model. The whole process will take a long time. We will make The child will go back first, wait for a while, and then come back. Yang Ping introduced the progress.

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

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

This technique selects some points on the epiphysis of the spine and blocks them, so that it grows slowly, resulting in uneven growth and development of various parts of the spine.

Scoliosis is the result of an imbalance in growth and development, and this imbalance is counteracted by epiphyseal blockade.

In theory, spinal deformities are automatically corrected during growth and development.

A simple bending model, the convex side grows slower and the concave side grows faster, so that the sides are not balanced, and eventually, the bend becomes straight.

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

This technique is currently used in simple deformity orthopedics in children.

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

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

This kind of operation uses the principle of epiphyseal block, which is called temporary hemi-epiphyseal block. Temporary means that the block produced by this operation is time-limited, not permanent. Restoring growth; hemi-epiphysis is where one part of the epiphysis stops growing while the other part continues to grow.

Like a simple bending stick, for the knee joint, if you control the inner part, the outer part keeps growing, the inner part grows slowly, the outer part grows fast, the knee joint is like an inward bending, then the normal knee joint will become an O shape, and vice versa. It becomes the X type.

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

This technique is fine for X- or O-shaped legs of the knee, as the deformity is simple, bending in or out.

But the spine is three-dimensional, it is very difficult to find the control point, and the degree of block cannot be grasped when finding the control point. The consequence of this is that the spine changes from one deformity to another deformity.

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

Yang Ping completed a large number of experiments in the system space, and also 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. Inside were the detailed drawings of the design of the external fixing frame.

When Professor Liang heard the detailed drawings, he waved his hand: It's enough to know that it's already at the stage of animal experimentation, and I won't look at the details.

Professor Liang is well-known in academic circles. He does not play a key role in publishing papers based on the results of his students. He will never be the first author. If he has no substantial participation, he will never add his name. Never rob students of their scientific research results.

He also constantly warned students that, no matter how the achievements of others 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 for intellectual property violations. If there is no punishment, the offenders are unscrupulous. Anyway, if I plagiarize you, I will gain both fame and fortune. Even if you sue, I will compensate you tens of thousands of dollars. matter, who is afraid of who. This greatly eliminates the enthusiasm of the true original creator.

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

Since Yang Ping said it could be made public, it would be okay to take 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 various parts, and group diagrams of application principle display.

Yang Ping explained the principle and some details of this device to the picture.

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

Yang Ping's scientific 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 of this kind of equipment to go from idea to drawing, and it is not necessarily successful.

Now that he has taken it out, he is already mature. Is it possible to study this just after graduation.

In fact, Yang Ping did not know how many times he failed in the system space before he succeeded, and the points consumed millions of points. If he failed again, he would not dare to consume points to continue.

Professor Liang is also not good at getting to the bottom of things. Anyway, no matter what the reason is, things are here, so he said: Your equipment is very mature, so you need animal experiments. We have a cooperative laboratory with the Chinese University of Hong Kong, which is Using experimental monkeys as a model to study scoliosis, this laboratory is located in Guilin, Guangxi. It has been in operation for three years and has accumulated a lot of data. Now the data is open to you, Director Hu, how many young monkeys are there in the existing model?

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

Yes, that's great. I was thinking of taking the time to go to Guangxi to see the experimental monkey base over there. Yang Ping knew that their laboratory was located in Guilin because of the convenience of obtaining experimental monkeys. Guangxi has the largest laboratory in the country. experimental monkey breeding base.

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

Professor Liang was a little unhappy: Don't wait, just now, just ask a few words now.

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

In front of everyone, Director Hu called to inquire about the situation of the Guilin Laboratory. Except for a few daily management personnel, the staff in the laboratory were all stationed by Concord and the Chinese University of Hong Kong in turn.

For the experimental monkey scoliosis model, you need to purchase the experimental monkey and then make the scoliosis model yourself, which requires a process. Therefore, if the experiment is launched soon, you must know whether there is enough stock.

Yes! Thirty-four baby monkeys! All have completed the health quarantine and immunization plan, and can be put into the experiment at any time. Director Hu replied.

Thirty-four, that's enough! Professor Liang calculated a little.

Let's all focus on doing experiments on Dr. Yang's topic. 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 paper, and the first batch of experiments will be done. Cases, let us observe first. Professor Liang did not want to take advantage of young people, but sincerely wanted to use his resources to help Yang Ping.

Thank you Professor Liang then. 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 was such that Yang Ping didn't mention it, he just followed his wishes.

Xiao Yang, you send the detailed experimental plan, they will complete the animal experiment, and Director Hu is responsible for the liaison on this topic. Professor Liang said a few words, and the cooperation on this topic was confirmed.

Cooperation on topics can drive everyone to make progress together, and more importantly, do not work behind closed doors.

This is the same as enterprise production. Mastering the core technology, the other can be done by upstream and downstream cooperative enterprises, and everything can be done by itself, which reduces efficiency.

After visiting the ward and visiting the operating room again, Professor Liang and Yang Ping had endless things to say, which made Director Han and Director Xia unable to intervene, and they just shook their heads and sighed.

In the evening, everyone had a meal together, accompanied by Professor Su, President Xia, Director Han, Director Tian, ​​several directors of the Department of Orthopedics, all doctors of the Department of Comprehensive Orthopedics, and the Union Advanced Study Group.

When Professor Su saw Yang Ping, he was very kind. If it weren't for the scene, he would pull 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.

In this Golden Knife Award, Yang Ping won the championship, Su Yixuan won the best equipment nurse, both of them won the award. Professor Su and his wife often chatted about this, and they laughed hard.

The two couples were also anxious, why didn't this girl tell her family about her love affairs, and she didn't bring Yang Ping to see her parents.

This time, Professor Su has also heard about the Xiehe and 301 robbing battle. He has been paying attention to the trend, and he does not know which hospital Yang Ping will go to. Based on his overall analysis, Yang Ping will probably stay put, but the mind of the young man is difficult. ponder.

In terms of getting the moon near the water, the Southern Metropolis Affiliated One is more advantageous, but Professor Su felt like a mirror in his heart.

Yang Ping is currently doing well in Sanbo, and he doesn't need to move the place. Even if he moves, if he really goes to Xiehe or 301, it will be better than Nandu Fuyi.

Therefore, Professor Su is neither in a hurry nor impetuous, as steady 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 wing, otherwise Su Yixuan will not be in Sanbo. Hospital work.

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

At a green dinner, everyone drank drinks, and Professor Su hurriedly raised his glass: Xiao Yang, this time the Golden Knife Award did a good job, especially the scoliosis machine, which made my heart skip a beat.

Professor Su has won the award. My method is a little improvement on the basis of my predecessors. Yang Ping should be humble in front of his old husband.

This child, Professor Su is happy in his heart. He should be humble when he should be humble, and proud when he should be proud. He likes this character.

When will you come to Fuyi, Nan Chen always mentions you. Professor Su put down the glass.

Xiao Yang and your son still have friendship? Professor Liang was surprised, and at the same time, he was also puzzled that Su Qingyun was also famous, so why didn't he do anything to Yang Ping.

Su Nanchen graduated from Union Medical College, and all clinical courses were completed at Union Medical College. Professor Liang was naturally familiar with it.

Looking at Professor Liang's puzzled eyes, Director Han understood. He just smiled. He Su Qingyun was in a hurry. No matter where he went, he had to recognize his old husband.
