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

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

The osteotomy itself can be destructive and interfere with the development of the spine, which can make the problem complicated.

If an external fixture can be used for orthopedics, all the difficulties will be solved, but the design of this external fixture is not easy to say.

Ideas become reality, and the distance between them is very far.

Returning to the doctor's office from the ward, Professor Liang sat down and asked, "What stage has your external fixator reached?" ”

Medical devices and drugs have strict processes from R&D to application, and medical devices are much more relaxed than drugs.

"The design has matured, and now we are ready to conduct animal experiments, and we need a batch of juvenile monkey models of scoliosis deformity, we are contacting to purchase experimental monkeys to find a way to make scoliosis models, the whole process will take a long time, we will let the children 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 countless research experiments in the system space, and has screened various techniques, such as epiphyseal blocking technology.

This technique selects points in the epiphysis of the spine and blocks it to slow down, causing imbalance in the growth and development of various parts of the spine.

Scoliosis deformity is the result of an imbalance in growth and development, which can be countered by epiphyseal blockade.

Theoretically, spinal deformities are automatically corrected during growth and development.

A simple curved model, the convex side growth slows down and the concave side grows faster, so that the two sides are unbalanced, 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 being used in the orthopedic treatment of simple joint deformities 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, X-leg or O-leg surgery can only be done with osteotomy and orthopedics.

This kind of surgery uses the principle of epiphyseal block, which is called temporary hemiepiphyseal block, which means that the block produced by this operation is time-limited, not permanent, and the block must be canceled to achieve the goal and let the epiphysis regrow; Hemiepiphysis is the process of causing one part of the epiphysis to stop growing while the other part continues to grow.

Like a simple bending stick, if the inner part is controlled, the outer part keeps growing, the medial part grows slowly, and the lateral part grows fast, and the knee joint is like an internal flexion, then the normal knee joint will become O-shaped, and vice versa, it will become X-shaped.

If it is an O-shaped leg and blocks the outside, the medial growth is fast, 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 for X- or O-shaped legs of the knee because the deformity is simple, that is, bending inward or outward.

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

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

Yang Ping completed a large number of experiments in the system space and consumed a lot of points, and finally obtained valuable data and improved the external fixator to the extent that it can be clinically practical.

Yang Ping asked Song Zimo to take out the mobile hard disk and connect it to the computer, which was a detailed drawing of the design of the external fixture.

When Professor Liang heard that it was a detailed drawing, he waved his hand: "I just know that it has reached the stage of animal experiments, and I won't look at the details." ”

Professor Liang is well-known in the academic circle, he does not play a key role in publishing papers on the achievements of his students, he will never be the first author, he will never add a name if he has not participated in the substance, the student is the student, and he will never plunder the student's scientific research results.

He also constantly admonishes students that the results of others, no matter how they are obtained, must be credited with the source when writing articles or citing them in public, indicating 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. This greatly obliterates the positivity of the true original.

Yang Ping didn't expect Professor Liang to be so serious about this matter, and immediately explained: "This is just a device drawing, just a part of the technology, and it can be made public." ”

Since Yang Ping said that it can be made public, then it doesn't hurt to see, and Professor Liang nodded in agreement.

The drawings in the mobile hard disk are opened, very detailed, decomposed pictures, three-dimensional pictures, pictures of individual parts, and group drawings of application principle display.

Yang Ping explained the principle and some details of this set of equipment in front of the picture.

This set of equipment is very mature from theoretical basis to mechanical design, and it can be fully used in clinical experiments, and now it is only supported by animal experimental data.

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

This kind of equipment goes from idea to drawing, bumps and bumps, and a whole team can take several years, and it may not be successful.

Now that he has taken it out, he is already mature, so can he study this just after graduation?

In fact, Yang Ping didn't know how many times he failed in the system space before he succeeded, and the points consumed millions of points, and if he didn't succeed, he didn't dare to consume the points to continue.

Professor Liang is not good at asking the bottom of the matter, anyway, for whatever reason, things are here, so he said: "Your set of equipment is very mature, just animal experiments, we have a cooperative laboratory with the Chinese University of Hong Kong, which is to study scoliosis with experimental monkeys as a model, this laboratory is located in Guilin, Guangxi, has been in operation for three years, has accumulated a lot of data, and now the data is open to you, Director Hu, ask how many young monkeys there are in the existing model?" ”

"These experimental monkeys are all cynomolgus monkeys, which should be very suitable for research, how old do you need to be monkeys? Less than six years?" Professor Liang asked.

"Yes, great, I'm just going to take a trip to Guangxi to see the experimental monkey base over there." Yang Ping knew that their laboratory was set up in Guilin because it was convenient to obtain experimental monkeys, and Guangxi had the largest experimental monkey breeding base in the country.

"I'll do it later!" Director Hu took note of Professor Liang's words.

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

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

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

Experimental monkey scoliosis model, you need to buy experimental monkeys and come back, and then make your own scoliosis model, which requires a process, so if the experiment is launched soon, you must understand whether the inventory is enough.

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

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

"All of them were concentrated to do experiments on Dr. Yang's topic. Xiao Yang, if you agree, we can cooperate at this point, and we can help you complete your animal experiments, what do you think? We will not name the paper, and when the first batch of experimental cases comes, let us give priority to observation. Professor Liang didn't 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 complete animal experiments, but Professor Liang's style is like this, so Yang Ping will not mention it, and go with his please.

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

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

This is the same as enterprise production, master the core technology, and the rest can be done by upstream and downstream cooperative enterprises, do everything by themselves, and reduce efficiency.

After visiting the ward, he visited the operating room again, and he had endless words with Yang Ping, which made Director Han and Dean Xia unable to interject, and the two just shook their heads and sighed.

In the evening, everyone had dinner together, accompanied by Professor Su, Dean Xia, Director Han, Director Tian, several directors of the Department of Orthopedics, all doctors of the Department of Comprehensive Orthopedics, and the Concord Training Group.

Professor Su saw Yang Ping, very cordial, if it wasn't for the scene, he would have pulled Yang Ping to sit next to him, since Yang Ping came back from the United States, Professor Su has always wanted to find a chance to meet Yang Ping.

This time, Yang Ping won the championship, Su Yixuan won the best instrument nurse, and both of them won the award.

The two couples were also anxious, why didn't this girl talk about love with her family, and didn't take Yang Ping to see her parents, she wanted to ask her several times, but she couldn't help it.

This time, Professor Su has also heard about the battle between Concord and 301, and has been paying attention to the trend, and he doesn't know which hospital Yang Ping will go to, with his overall analysis, Yang Ping is estimated to be in place, but the young man's mind is difficult to figure out.

If you want to say that the building near the water gets the moon first, the southern capital is more advantageous, but Professor Su is like a mirror in his heart.

Yang Ping is currently doing well in Sanbo, and there is no need to move the place, even if he moves, if he really goes to Xiehe or 301, it is stronger than Nandu Fuyi.

Therefore, Professor Su is neither impatient nor impatient, steady as Mount Tai, how to do it, he has already planned, he knows that neither Yang Ping nor his daughter wants to develop under his wing, otherwise Su Yixuan would not work in Sanbo Hospital.

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

At the green dinner, everyone drank drinks, and Professor Su hurriedly raised his glass: "Xiao Yang, this Golden Knife Award has performed well, especially the scoliosis, which makes me feel shocked." ”

"Professor Su has won the award, and my method is a little improvement on the basis of my predecessors." Yang Ping should be modest in front of his father-in-law.

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

"When you come to Attached One to take a look, Nanchen always mentions you." Professor Su put down his glass.

"Xiao Yang still has a friendship with your son-in-law?" Professor Liang was surprised, and at the same time puzzled, this Su Qingyun Aicai was also famous, why did he not make any action against Yang Ping.

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

Looking at Professor Liang's puzzled eyes, Director Han understood, he just smiled, what was he Su Qingyun anxious about, no matter where he went, he had to recognize him as an old man.
