After seeing off Professor Liang, Yang Ping returned to the hospital, sorted out the information, and brought it to the patient room for distribution.
Huang Jiacai is already waiting downstairs. They are going to the Digital Medicine Laboratory of Nandu Medical University.
This laboratory has been studying the "digital human" project, but due to financial constraints, it was difficult to continue the research.
Huang Jiacai took the initiative to find Professor He Jirong, the head of the laboratory, and proposed to establish a cooperation, with Ruixing Company providing continuous research funds.
At that time, Professor He was very skeptical. "Digital Human" was a basic medical research, and no company was willing to invest in it.
This kind of purely basic project cannot generate profits and the company has no interest in it.
Enterprises like short-term projects that can make money quickly.
At that time, Professor He suspected that Boss Huang had other intentions. When Huang Jiacai showed him the cooperation agreement, there were no terms requiring profit, but only the sharing of the results of the cooperation project.
The cautious Professor He took the agreement back and discussed it for several days before meeting Huang Jiacai again with the attitude of giving it a try, and the two signed the agreement.
After signing the agreement, Huang Jiacai made a phone call on the spot. He received the first scientific research fund from Ruixing Company---20 million in the Nandu Medical University account left by Professor He.
Twenty million!
Just give it as you say, Professor He was a little dazed at the time.
At that time, Professor He saw Huang Jiacai's sincerity and courage, and felt that his project had hope.
This is the first time Yang Ping has met Professor He, and it is also the first time to use Professor He's "Digital Human" technology.
Yang Ping wants to use "digital human" technology to establish a dynamic model of Fang Faquan's motion system.
Then use the computer to optimize the force line, calculate the location and direction of the osteotomy, determine the pinhole position of the external fixator, and dynamically simulate the correction process.
Yang Ping can perform these simulations using experimental bodies in the system space.
However, the experience gained in the system space can only serve as his personal surgical reference, and he is not satisfied with this.
He wants to elevate these experiences into science and technology that can promote medical progress.
Then, using computers for surgical simulation is the best choice.
If you can use the data you obtain in the system space for computer modeling, then computer simulation technology will become very accurate.
Professor He is already waiting at the door of the experimental building. There are many laboratories in this experimental building, and the digital medicine laboratory is just one of them.
Such respect for Huang Jiacai and Yang Ping is not because Professor He bows to his sponsor, but because Huang Jiacai, the boss with a high school education, is really far-sighted and has great respect for Professor He and researchers.
Professor He and Huang Jiacai have become close friends.
Huang Jiacai brought Yang Ping here today. He must take it very seriously.
Of course, he still doesn’t know the true relationship between Yang Ping and Huang Jiacai.
The Digital Medicine Laboratory only occupies half of the third floor. After introducing each other and exchanging pleasantries, Professor He brought Yang Ping and Huang Jiacai to their usual offices.
"If it's convenient, can we start modeling now?" Yang Ping proposed to start working as soon as he sat down.
"Okay, I'm ready. Mr. Huang said that Professor Yang needs to build a model of the walking function of the lower limbs this time. It just so happens that we have perfected the simulation of the lower limb function. There was no digital human function module before, and the construction of this model only took a few months.
Time will definitely not be enough to complete it. Now there are digital human lower limb function modules. On this basis, adding an external fixator module, the modeling can be completed in just a few days. In the future, when these modules are matched and mature, the modeling can be completed in a few hours." Professor He
I am very happy that someone is using his technology, which gives me a sense of accomplishment.
Huang Jiacai said to Professor He: "Professor He, just call me Xiao Huang, don't call me Mr. Huang, Mr. Huang, it will look awkward."
Professor He felt very good about this young man and immediately said: "We had just entered into the simulation of lower limb function before, and we had difficulties in funding. It happened that Xiao Huang was generous and gave 20 million. We worked hard and just completed the construction of lower limb walking function not long ago.
"Model."
At present, digital humans are still in the anatomical human stage, and only the lower limb motor functions have entered the functional human stage.
Professor He asked a graduate student to take Fang Faquan to the sports information collection room.
Professor He, Yang Ping, Huang Jiacai, and several graduate students are in the computer room next door.
The two rooms are separated by a glass wall and connected through a small door.
The graduate student told Fang Faquan to follow the instructions, explained each instruction clearly, and demonstrated to Fang Faquan.
The young man is quite smart and has good receptive ability. He quickly learned how to follow the instructions.
There are many sensors on the floor of the sports information collection room and all over Fangfa's body. There are high-definition high-speed cameras at different angles on the ceiling and walls to capture the motion status from different sides.
First, walk slowly, then run, then jump, stop suddenly, and turn.
Each movement state needs to capture a lot of dynamic pictures.
On the screen in the computer room, a model man was displayed, doing exactly the same movements as Fang Faquan.
This model human is a stripped-out human movement system, with only bones, joint capsules, ligaments, muscles and tendons, etc.
This image is composed of a three-dimensional reconstruction of bone CT and MRI of muscles and tendons, combined with a digital human module.
After collecting Fang Faquan's motion information, the screen was divided into two halves.
Half of the models are lame with complete atrial hair, and the other half are models with normal atrial hair.
The latter model is generated based on the modification of the previous model.
Then use animation to demonstrate the dynamic process from deformity to normality.
Yang Ping explained to Professor He and graduate students the methods of surgical intervention, the information that surgeons need to obtain, and how models can assist surgeons.
These people all have master's degrees and PhDs with high IQs, and are computer graduate students with medical backgrounds. They quickly understood what Yang Ping said.
During the orthopedic process, they added the influence of the external fixator model and found the best distraction core line, which is the osteotomy line.
Based on biomechanics, find the optimal distribution point of pinholes of the external fixator.
Then let the external fixator stretch to complete the deformation from the deformity to normal.
"Give us three days, and we will give you a satisfactory digital model." Professor He was very confident after hearing this.
The combination of digital technology and clinical practice exerts tremendous power.
"If we have an independent supercomputer in the future, this project will progress faster."
Owning a supercomputer is Professor He’s dream.
Huang Jiacai encouraged the professor: "Take your time. In the near future, we will have everything. Not to mention supercomputing, even supercomputing clusters will be realized."
This project is the most basic project in Huang Jiacai's plan, and he will pool funds to support this project.
The company is currently short of funds and can only provide so much. When it makes money in the future, it will continue to inject funds.
"If funds are sufficient, we can expand the research team and complete the modeling of the movement functions of the lower limbs, spine and upper limbs within one year. Among the three, the most complex is the function of the upper limbs, especially the hands, which takes a longer time.
"Professor He is full of confidence.
"Professor He, you can study with peace of mind in the future. If you have any difficulties, just tell me. We will continue to support this project." Huang Jiacai gave Professor He reassurance.
Professor He has no doubt about Boss Huang's strength at all: "Xiao Huang, I feel relieved because of your words. To tell you the truth, our basic project is most afraid of being half abandoned."
Computer assistance in medicine will play an important role in the future.
For this kind of orthopedic surgery, if you rely on experience to guide the surgery, it will be difficult to achieve the desired effect.
With computer simulation, everything becomes very easy.
In the system space, Yang Ping can rely on a large number of case simulations to achieve the best surgery. He has always hoped that he can achieve the best surgery without the system. This is what Yang Ping pursues.
The system is just a tool for him, and now he wants to make a system for every doctor.
Digital People can help Yang Ping achieve this goal.
If one day, digital humans can realistically simulate the human body in terms of anatomy and function, all patients can use digital humans to model and simulate surgeries, and then combine the data with surgical robots or computer-assisted equipment to make surgeries more convenient.
Easy and precise.
In the future, digital humans can be combined with virtual reality technology to develop a doctor training system so that doctors can repeatedly train certain surgeries.
With digital people as the core, many technologies can be developed.
In this way, every doctor has a powerful plug-in.
Yang Ping and Professor He continued to discuss the details of the whole lower limb functional modeling of atrial fibrillation.
Yang Ping stayed in the Digital Medicine Laboratory of Nandu Medical University all morning. At noon, Huang Jiacai hosted a dinner for Professor He and all the researchers in the laboratory.
Professor He was very excited at the dinner. This is what intellectuals pursue---focusing on down-to-earth scientific research.
Now some people are giving him investment funds, and they respect him very much, without making any demands or intervening in scientific research.
Isn’t that what people who do research dream about?
Professor He has decided to cooperate with them. There is no point in judging or winning awards.
As long as there are funds for scientific research, there is no harm in investing all his energy in this life.
