medical simulator

To be honest, this is a hard work in MRI reading in hand surgery. At present, there is no shortcut.

Zhou Cheng was able to help Wang Huan list out the approximate levels of the different levels, and it was already exhausting: "It depends on the shape of the nerves and blood vessels. Apart from the basic skills and anatomical knowledge of the specialist, it is also necessary to have a deep understanding of the basics of MRI. principle."

"We know that nuclear magnetic imaging mainly relies on the relaxation of HO..."

"Display characteristics of nerves in MRI: nerves usually appear as areas of high signal intensity, because the lipid myelin sheath around nerves has high repellency of water molecules, resulting in a lower signal in surrounding tissues than in nerves.

"The principle of imaging is: the display of nerves mainly depends on T2-weighted imaging, that is, under certain scanning parameters, the T2 value of nerve tissue is longer, so neural structures with high signal intensity will be displayed in T2-weighted imaging."

"Display characteristics of blood vessels: blood vessels usually appear as areas of low signal intensity, because oxyhemoglobin in the blood inhibits the generation of MRI signals, and the lipid myelin sheath around blood vessels also inhibits the generation of signals.

"Imaging principle: The display of blood vessels mainly depends on T1-weighted imaging, that is, under certain scanning parameters, oxyhemoglobin in blood has a longer T1 value, so blood vessel structures with low signal intensity will be displayed in T1-weighted imaging. It's different again."

"So we usually look at the nerves at the T2-weighted level, and the blood vessels at the T1-weighted level. This requires a lot of practice..."

"There is no shortcut to learning, but there are certain shortcuts. This is slightly related to the way we humans learn. You can form your own unique corresponding anchor points when reading films."

"Do you know what the learning anchor is? It is a tool for you to assist learning, just like the spatial memory method, the palace memory method, looking for a substitute——"

"For example, some people are great masters in the mathematics department, and some people are very sensitive to the three-dimensional structure of space, so they are very keen in learning number theory and virtual and real numbers!"

"There are also people who study fine arts, who have a three-dimensional sense..."

"There are also people who are sensitive to words..."

"There are also people who are very familiar with refining. They can quickly disassemble the key parts of a large article, and after one pass, they can restore the general meaning. This is their sensitivity to words."

"This kind of person is born with the advantage of learning. He can remember a lot of concepts and content, and when he masters them, he can write very well. This is organizational ability."

"Some people are sensitive to numbers. You may ask them to memorize some words alone, which is very difficult."

"But once they are linked with numbers, they will never forget them for life. Even when they speak, they may have to extract the numbers first."

"There are still some people who structure the knowledge system into a space structure, and place different things in different nodes."

"That's the anchor for learning."

"If you can list the nerves, blood vessels, muscles, and tendons as different objects in the process of reading the film, and find a relatively exaggerated pictogram or substitute, then when you read the film next time, you will see it again. These things will be more clearly highlighted in front of your eyes."

"For example, Wang Huan, you are afraid of mice, aren't you?"

Wang Huan was shocked when he heard the words, and shook his head violently, as if hearing this word, he formed a fear memory in his muscles, and his expression was terrifying.

Seeing this, Zhou Cheng said: "That's right, that's it. As long as it is a mouse, no matter it is a picture, a text, or a related word, its sound, etc., you can immediately respond to it. If you can read it Some parts of the film are supposed to be related to these, so when you read the film in the future, the first thing you find is these memorable things.”

"Master, can you not compare the nerves and blood vessels to the mouse?" Wang Huan himself didn't like to say this word, and he used English instead.

"Okay, you can replace it however you want, I'm just giving you an example."

"This, I asked Yang Yifeng specifically for you. That's how he learned it. His memory method is a compass, and of course it's not just a compass. He is very sensitive to the structure of the plane. He can even put a lot of Articles are stored in the memory in the form of multiple rings, which can be retrieved at any time."

"I never thought I could learn like this." Zhou Cheng smiled wryly.

There is a huge gap between a genius and an ordinary person. It can be said that Zhou Cheng has such a deep knowledge reserve. It can be said that it is not a coincidence, but the accumulation of time. Zhou Cheng has been immersed in the simulation world for many years, all by rote Hard back, relying on opening and hanging to complete the directional memory of some things.

But Yang Yifeng is different. His time is limited. Although his current knowledge reserve is not as good as Zhou Cheng's, his learning efficiency per unit time is not known to be how many times that of Zhou Cheng's.

And even though Zhou Cheng reproduced other people's talents, including An Ruo.

But they have only slightly improved their talents in recent years. People like Yang Yifeng have been like this before, so they have accumulated a lot of things, but you usually don’t know it when they don’t show it on weekdays.

"Thank you, master." Wang Huan also knew that the teacher had put a lot of effort into his studies.

"By the way, master, the two senior brothers and I have already downloaded the closed beta version of the app you asked us to download. The two senior brothers also gave some feedback. He said, if you want this game to be more interesting, you can Make a skills exchange system."

"For example, if a player has any skills, they can be packaged into skill scrolls and sold, so that other players can pass the level..."

When Zhou Cheng heard this, his expression was wonderful: "They really use this thing as a game, don't they?"

"I'm using it as a learning app, not a gaming app."

Wang Huan nodded again: "Yes, master, this is a learning app, but the two senior brothers said that if players can't kill monsters even though they have skills, it means they have a problem with their operation, so they are looking for ways to beat monsters." When killing monsters, look for the logic and principles behind the operation."

"This can stimulate the player's desire to learn even more. After all, in the game you developed, teacher, every surgical step has to be chosen, and the threshold mechanism is set in advance..."

"For example, joint replacement surgery cannot be performed before reaching the proficiency level, and it is actually a bit difficult to obtain such a skill scroll. It is better to let other players earn money, get game funds, and get more. Skill."

"At the same time, when other players have already acquired skills, they still can't pass the level, that is, they are too good. Brother Peng Lingli said that the word "vegetable" can stimulate the game players' desire to learn." Wang Huan relayed very seriously. .

Hearing this, Zhou Cheng was thoughtful.

To be honest, the game that Zhou Cheng liked to play before was StarCraft, the stand-alone computer version, Zhou Cheng could play seven in one.

But when you are playing against other people, that operation is really not something you can practice. Other people's APM can reach hundreds in one minute.And it's still an effective APM, how do you compare?

Even if you practice too many times, you will not be able to improve effectively. It requires talent, so it is difficult to get started.

But some of the games being developed now seem to be not like this.

Moreover, the mechanism proposed by Wang Huan and Peng Lingli is not difficult, so it seems to be feasible.

"Okay, I'll think about it." Zhou Cheng nodded back.

"There are more." Wang Huan continued.

"Brother Guo Lin has been involved in games a lot. He suggested that you, Master, change the name of the game during the public beta. Don't call it a doctor simulator. It is better to call it a medical persuasion game. It will attract some unique interests. players."

"Of course, if your position is not to make money, you can do this." Wang Huan said again.

Zhou Cheng was a little dumbfounded, what the hell is this Guo Lin, but their suggestion is indeed effective.

But in fact, Zhou Cheng's plan is not only that.

"You go back first and look for anchor points or substitutes for nerves and blood vessels when reading the films. I'll think about it later." Zhou Cheng said.

To be honest, the reason why Zhou Cheng wants to develop such an app is that Zhou Cheng’s purpose is to broadly improve the professional ability and level of relevant practitioners, and even through this game or app, it can objectively reflect the normal level of a doctor.

Of course, this ambition is a bit big.

If you want to take into account the ability to be interesting, then it is a bit of putting the cart before the horse, but if there is no certain amount of users, then the significance of designing this app is not so much.

In the current market, there are so many recreational games with only two elements of fighting monsters and skills, so it is difficult to attract people.

Moreover, this app is actually a bit boring from an objective point of view, and it is not particularly suitable for passing time. Therefore, it may be better to add some world view and story elements.

After all, a mature game should have a storyline inside.

Thinking of this, Zhou Chengcheng went to find Yang Yifeng again, and made a phone call: "Yifeng, how did you design the storyline of the doctor simulator? Don't worry, how you design, the game will be presented in the end, and It can be written and posted at the same time. It is better to be a little more detailed and attractive."

The plot of the game is an important part.

"Brother Zhou Cheng, don't worry about this. I'm better at writing games than you. I have prepared several sets of plots. The protagonists' initial backgrounds are different, so the plots of the stories they encounter will be different."

"Let me tell you, now I have listed a total of more than a dozen initial identities, and I have invited some other authors who can write stories about doctors to help write together."

"Probably there are old doctors from township health centers, with regular training, master's degree, and pharmaceutical agents who have changed their careers, etc."

"Speaking of this, I'm not bragging. I'm much more professional than you." Yang Yifeng should not be busy with experiments at the moment, so he is very interested.

"I believe this, thank you for your hard work, and I will settle it for you when the time comes." Zhou Cheng said.

The price he offered Yang Yifeng before was one hundred thousand words, which he thought should be high enough, but later he realized that if Yang Yifeng wrote more novels of his own, it would be much more than one hundred thousand words.

It's a pity that Zhou Cheng himself doesn't know much about this.

"It's enough for you to pay my friend some hard-earned money. After all, they used to major in medicine. Although they didn't make it to this point in the end, they actually hope that this industry will develop better and better."

"Okay, not much to say, I also called some people to conduct an internal test, and they will give me some feedback."

"However, Brother Zhou Cheng, one of the opinions I have already received is that this game, we'd better not make it difficult for the sake of embarrassment. It's best to set up a simple professional official forum, and release some strategies or documents in due course."

"It is convenient for communication between peers."

"In addition, one more thing is that you have to prepare Brother Quan. I guess the next one to ask him to develop a game like this may be the Department of Cardiology. Someone in this area has already asked me."

"What I think is that it would be very troublesome to add the modules of the Department of Cardiology, and the treatment principles, specialization, and different skill levels of different disciplines must be set by their specialists. Perfection, I don’t know how long it will take, and I don’t know if it will be successful.”

"So I think it's better to let them do it themselves, and it will affect the quality of our game." Yang Yifeng said somewhat hurt.

"Well, okay, we're just doing our orthopedics department, we don't care about other departments." Zhou Cheng replied with a smile.

I don't know how long it will take?I don't know if it will be successful.

Zhou Cheng is almost certain that it will be difficult to succeed, because as long as different skills are placed in different professors, they will have different understandings. As for the division of levels, it needs someone who has a very good grasp of skills to be able to clarify the levels inside.

Unless there are people in other departments who can perfect all the skills of common diseases and even define perfection, otherwise, this project will definitely not be able to be replicated.

Zhou Cheng can understand the workload.

Just dividing different levels of different skills, and re-setting the levels of clinical diseases, there are as many as tens of thousands of entries. The workload and complexity are just a joke...

Yang Yifeng then said: "Brother Zhou Cheng, can I ask you a question? You don't know all the common diseases of orthopedics and spine very deeply and thoroughly, do you?"

"Guess?" Zhou Cheng asked without answering.

"Beautiful! I accept."

"Stop talking, I have a call from here." Seeing Chen Tingye's call, Zhou Cheng quickly hung up.

"Professor Chen?"

"Xiao Zhou, can you spare time to come to the operating room in half an hour? We will transfer a patient to our hospital after amputation. Can you perform a limb salvage operation on him... "Chen Tingye's mouth was just a request, without any courtesy.

Chapter 469 You call this a stupid way?

"Ah? Professor Chen?" Zhou Cheng went down to the operating room, and after meeting with Chen Tingye, what Chen Tingye said made Zhou Cheng's steps stiffen and his expression complicated.

Finally, he stopped and looked at Professor Chen Tingye with a bitter face.

Chen Tingye is the Ward Director of the First Department of Orthopedics, and is currently the leader in the Hand Surgery Department of the Affiliated Hospital of Shonan University.He is also Associate Professor Ning Xihua's mentor and former superior doctor——

Chen Tingye may also feel that what he said to Zhou Cheng in person was inappropriate, so he eased his emotions and said: "Xiao Zhou, I am just explaining the situation calmly to you, and I am not blaming you. Right, you and I belong to the orthopedics family."

"I didn't treat you as an outsider, so I told you these things. If I saw an outsider, I could have kept it all a secret."

"It's not that when you were in Changshi, you taught Wei Hong from the Second Affiliated Hospital of Shonan University, which put a lot of pressure on Ning Xihua." Chen Tingye's tone was serious, and his explanation was very straightforward. .

Amputation of limbs to save life, and then replantation of limbs to restore limbs. This kind of surgery is a pioneering surgical concept. Zhou Cheng was the first to propose it. At that time, Zhou Cheng did not have much contact with the Affiliated Hospital of Shonan University. relation.

Although the creation of the concept of surgery is far less difficult than subverting the foundation, as the founder, Zhou Cheng has the deepest understanding.

When he was in the Orthopedics Department of Changshi Hospital of Traditional Chinese Medicine, Wei Hong, who was also the "inheritor" of the Hand Surgery Department of the Second Affiliated Hospital of Shonan University, went down to follow Zhou Cheng for a period of time, and now he is doing a good job in the Second Affiliated Hospital. It is equivalent to Zhou Cheng personally brought it...

As for Ning Xihua, also an associate professor, about the same age as Wei Hong, he saw that Wei Hong was doing so enthusiastically, and then the lower-level hospital called him to have a consultation operation, and Ning Xihua also went.

He also didn't want to fall behind others and embarrass Chen Tingye, so he was studying the replantation of severed limbs by himself.

But this thing—

Whether someone takes it or not is two different surgeries.

not to mention?

The person who took Wei Hong was still Zhou Cheng. Therefore, Wei Hong, as an associate professor, could carry out the work now. Ning Xihua felt that he would not be weaker than him, so he figured out the basic theories and so on, and started to be the chief surgeon.

The result now is that even though Chen Tingye went, he couldn't continue the severed limb. In fact, the places that should be sutured have already been sutured, but the sutures are not particularly good. It may be that the affected limbs, blood vessels, etc. are all lost. active.

Also, the time has passed...

The most difficult part of replantation after amputation is not the proximal stump of the amputation, but the distal end of the amputation. There is a time limit, that is, it must not exceed 24 hours.

After being away from the body for too long, it is difficult for the gods to be revived.

The problem now is that when the amputation was performed to save his life, he was out of blood for a while, and then Ning Xihua fiddled with it for a while, and then Chen Tingye fiddled with it, and now he was transferred to the Affiliated Hospital of Shonan University.

24 hours have passed.

"Professor Chen, that's not what I mean either." Zhou Cheng restrained his inner emotions.

How to put it, now it seems that the relationship between Ning Xihua and himself is naturally closer than that of Wei Hong, but when he and Wei Hong worked together, Zhou Chengcheng couldn't figure out who Ning Xihua was on duty.

How could he have thought of so much, and he never thought that he was just cooperating with others to do a new project at that time. At that time, Wei Hong took the initiative to come to the door, and it would bring such a big impact to Ning Xihua, whom he now knows and is familiar with. pressure.

"Professor Chen, at that time last year..." Zhou Cheng still had to explain a few words.

Chen Tingye didn't want to waste any more time: "The past has nothing to do with the present, Xiao Zhou, you must take a good look at it, if you can save it, that's the best, if you can't, then you can only go and get along with it." The patient talked with his family about re-amputation."

After the amputation, the severed limb was replanted, and now it is going to be amputated again.

Such a toss, what kind of family members will be angry?

However, this kind of thing has been discussed before, so I don't blame Ning Xihua.

At present, there are very few hospitals and doctors who can perform such operations. It is only natural that they are not successful, and it is only a miracle that they succeed.

However, before finally losing hope, anyone still hopes to have a chance.
