medical simulator

Liu Shiyu was a little puzzled, but An Ruo knew Fang Yun, after all, he lived in front of his house before: "Xiao Fang?"

"Teacher Yang, sister An Ruo, and this sister..." Fang Yun saluted one by one.

Yang Yifeng quit at that time and stood up: "I am 24 this year, and all three of them are 27!"

Yang Yifeng was telling the truth.

Among the people present, he was the smallest, but he looked the biggest, even An Ruo and Liu Shiyu were bigger than Yang Yifeng, and so was Fang Yun, who was 27 this year.

Yang Yifeng's words sounded okay, but Liu Shiyu quit, and age is generally a taboo for girls.

Hit Yang Yifeng: "Who are you calling old?"

"Everyone is old except you." Yang Yifeng's desire to survive was extremely strong.

Zhou Cheng immediately rolled his eyes, and patted Fang Yun who was at a loss: "He just likes to joke like that, so don't mind!"

"However, we are all the same age. From now on, you should address them as peers. Don't call me teacher, so as not to break the taboo!" Zhou Cheng confessed, bypassing the problem of addressing.

Yang Yifeng seemed to be joking, but in fact he was secretly happy.

After Zhou Cheng took his seat, he stared at Fang Yun calmly, and asked Zhou Cheng, "Brother, how did you manage to get such a general?"

Fang Yun's strength was recognized by Yang Yifeng, especially this awesome qualification, Yang Yifeng was surprised when he saw it.

How can there be such a person? After watching the operation, he knew that he was an orthopedic resident trainee, and also a BT version professional resident trainee similar to Zhou Cheng.

Let his eight-year Ph.D. be very embarrassing.

"Fang Yun came here by himself, maybe he wants to stay with us for a while. It's better this way. In the future, we can work three shifts." Zhou Cheng was secretly happy.

Fang Yun's strength has been raised to a very high level.

Hearing this, Liu Shiyu frowned, and looked at Fang Yun with burning eyes.

She knows Yang Yifeng's talent and strength best. On Zhou Cheng's side, Yang Yifeng has told her many times that he is too strong. This Fang Yun?

To be able to take turns on duty with Zhou Cheng and Yang Yifeng is definitely not to be underestimated.

"Does Xiao Fang have a girlfriend?" Liu Shiyu asked immediately.

When you are older and meet for the first time, it is correct to ask, but the main reason is that she wants to take advantage of her other best friend.

Fang Yun nodded: "Sister Shiyu, yes, she is also in Shashi now."

Hearing what Fang Yun said, Zhou Cheng had an idea and asked, "You came to Shashi, your girlfriend didn't ask for it, did you?"

Fang Yunqi shook his head: "No, my teacher arranged for me to come here. Teacher Zhou."

"Is your girlfriend in the same company?"

"It can be regarded as my colleague. She is now a graduate student in orthopedics..." Fang Yun said.

Chapter 445 The leader pk proceeds...!

"There's no emergency room now, right? So let's start with the class now?" After Yang Yifeng had dinner with Zhou Cheng and the others, An Ruo and Liu Shiyu made an appointment to go shopping together.

Zhou Chengcheng and Yang Yifeng came to the waiting room of the emergency department, and together with Fang Yun, it was an official meeting of the prototype of the team!

However, Yang Yifeng proposed a battle, that is, everyone is now an employee in the same unit, and when working in the future, they must work in the same environment.

It is no longer the kind of student stage before.

At this time, during the work period, in academic activities and in the experimental team, it is necessary to make a plan and agreement in advance as to who will take the lead.

The agreed method is very simple, that is to conduct face-to-face academic battles, and there is no time for preparation in advance.

Hearing this, Fang Yun hurriedly said: "Teacher Zhou, brother Yifeng, can you wait a moment, I'll find some paper and take some notes."

Fang Yun was afraid that he would not be able to keep up with Zhou Cheng and Yang Yifeng's thinking, and that he would be baffled by what he heard, so he could go back and practice for a while.

"Then tell me, how do we start, how do we determine a better direction for discussion?" Zhou Cheng thought Yang Yifeng's suggestion was good.

What's more, Zhou Cheng seldom confronted Yang Yifeng, Yang Yifeng had always followed him, but now Yang Yifeng wanted to stand up and call the shots, Zhou Cheng could understand.

Moreover, Zhou Cheng also supports the current method of 'chatting', which is to compete for knowledge reserves.

Indeed, asking Yang Yifeng to do things with him without evidence or proof doesn't seem like a name.

"You and I are both in trauma surgery. In trauma surgery, we won't discuss in detail about ankle, trauma, wrist, etc. We choose a topic of orthopedics other than trauma surgery."

"Total hip replacement is a relatively mature operation now, and there is a kind of MITHA in total hip replacement. I will ask you about your understanding of this operation, its development prospects, etc., and then you can ask me a similar question."

"Let Fang Yun be the judge. If you lose the game, you will assist me in my work in the future, whether it is clinical or scientific research. It's the same if I lose!"

"It's fair, it depends on the knowledge reserve." Yang Yifeng said very formally.

"Okay!" Zhou Cheng agreed without hesitation.

There was no time for Fang Yun to take notes at all. Fang Yun's knowledge reserve was relatively small. After a while, he realized what MITHA meant.

Minimally Invasive Total Hip Arthroplasty (MITHA)!

Fang Yun is a little nervous. This is a business that has not yet been launched in China, and he feels that it is of little significance, because total hip replacement surgery itself is already very mature.

Zhou Cheng thought for 15 seconds and organized his language a little: "MITHA is a new technology used in total hip replacement surgery. Minimally invasive is its concept. Compared with traditional surgical techniques, it can reduce postoperative Pain, shortened recovery period and reduced risk of complications."

"The main feature of MITHA is that the surgical incision is smaller and the tools and instruments used are more delicate. This results in less postoperative pain, faster recovery, and a shorter hospital stay. Since MITHA is less traumatic to soft tissues, it There are also smaller incisions and scars after surgery, which is also good for the patient's appearance and physical self-perception."

"The surgical instruments used by MITHA are more refined, the difficulty and risk of surgery will increase, and a higher level of technology and experience is required. In addition, the cost of MITHA is relatively high, which may increase the burden of medical expenses."

"Therefore, it is somewhat difficult to widely apply it in China." Zhou Cheng first started the topic from the perspective of overall planning.

Yang Yifeng is naturally dissatisfied with such depth: "You have to explain the challenges and limitations of MITHA clearly, and you can't get confused. And what are the basic skills of MITHA?!"

Although the question Yang Yifeng asked was vague, it was the most primitive part.

Zhou Cheng replied without hesitation: "Minimally invasive surgical instruments: including micro-hammer, drill, bone saw, bone forceps, bone drill, bone expander, etc. Stereotaxic system: used to accurately locate surgical instruments and surgical sites, improve surgical accuracy."

"Special hip replacement prosthesis. These are raw materials."

"MITHA usually operates through two smaller incisions. One of the incisions is used to place the stereotaxic system, and the other is used to place surgical instruments and prostheses." Zhou Cheng did not tell the whole operation process, that is Waste of everyone's time.

"Restrictions: The instruments of MITHA surgery are more refined, and the difficulty and risk of surgery will also increase. The learning cycle is longer, and it is difficult to get started without guidance.

"The incision is smaller and the surgical field of view is limited. This may affect the precision and safety of the procedure. Also, MITHA surgery may not be suitable for some patients, such as obese patients, elderly patients and osteoporosis patients etc.

"The cost is relatively high, and the cost of seeing a doctor for patients is relatively high."

Yang Yifeng nodded again, thought for a while about Zhou Cheng's answer and the omitted part, and felt that it was almost the same.But such an answer still did not meet Yang Yifeng's request to Zhou Cheng.

At least it didn't surprise him, it was just a simple conceptual understanding.

Fang Yun was a little confused, his eyes were bright and complicated, maybe he was excited because he felt that he could learn more, but he was also disappointed because he learned so little!

"The development history and current research progress of the MITHA positioning system? If it is to be widely used in China, how do you think to reduce the cost?"

Zhou Cheng frowned slightly, and began to quickly mobilize his knowledge reserves. If he hadn't gone through a long simulation, he might not be able to answer: "In the late 20s, computer navigation technology began to be used to assist hip replacement surgery. Early The current positioning system uses photoelectric probes for positioning, and its positioning accuracy and stability are poor.

"In the 90s, positioning systems using optical sensors for positioning appeared, and their accuracy and stability have been significantly improved.

"In the early 21st century, the magnetic positioning system began to be used in hip replacement surgery. The system uses magnetic sensors for positioning, and its accuracy and stability have been further improved.

"In recent years, some research institutions have begun to try to combine robotics with the MITHA positioning system, and developed some hip replacement robots with autonomous control functions. These robots can achieve more accurate hip replacement surgery, but their cost and technical difficulty are relatively high." High, still needs further research and improvement.

"Current research progress is mainly focused on further improving the accuracy and stability of the MITHA positioning system, exploring new materials and technologies for prosthesis design and implantation, and improving surgical procedures and safety."

Yang Yifeng shook his head: "The development process is detailed enough, but the research progress is not detailed enough."

"Accuracy and stability, you should explain separately." Yang Yifeng increased the difficulty.

Any problem, as long as it continues to deepen, will enter an unsolvable level. It is not necessarily unsolvable, but it can definitely touch the edge of the knowledge system!

This is academic battle!

"About precision!"

"Improvement of sensor accuracy: The sensor used in the MITHA positioning system is one of the key factors for positioning accuracy. By improving the design and manufacturing process of the sensor, the accuracy and stability of the sensor have been improved. For example, the new sensor uses ultrasonic waves for position measurement, Higher positioning accuracy can be achieved."

"Improvement of the positioning algorithm: The MITHA positioning system converts the data collected by the sensor into the position information required for surgery through algorithms. At present, researchers mainly improve the positioning algorithm to improve the positioning accuracy of the MITHA positioning system. For example, using neural network algorithms and depth learning algorithm, which can improve the recognition accuracy of pelvis and femur position."

"Application of [-]D reconstruction technology: [-]D reconstruction technology can reconstruct multiple [-]D images into a [-]D model to improve the recognition accuracy of the pelvis and femur during surgery. For example: apply [-]D reconstruction technology to the MITHA positioning system to improve positioning precision."

"Development of real-time positioning and navigation technology: Real-time positioning and navigation technology can track the patient's position and posture in real time during surgery, thereby improving positioning accuracy. Currently researching ways to combine with MITHA."

"About stability!"

"The improvement of robot control technology, adding algorithms, has been explained above."

"The hardware of the MITHA positioning system is one of the key factors for its stability. More advanced sensors and actuators need to be developed to improve the accuracy and stability of the MITHA positioning system."

"Improvement of the human-computer interface: The human-computer interface of the MITHA positioning system is one of the key factors for its stability."

"Application of simulation technology: Simulation technology can conduct virtual tests on the MITHA positioning system, so as to detect problems in advance and make improvements to improve its stability and accuracy."

Yang Yifeng glanced at Fang Yun, and found that Fang Yun was completely confused!

Fang Yun is not bad. The current surgical technique is excellent, but the knowledge reserve and scientific research ability are still a little lacking.

But the above is only the current research progress, not Zhou Cheng's own thinking.

"If it is to be widely used in clinical practice in my country, we must develop it ourselves. What do you think is the most likely indicator for the mature application of MITHA? How to develop it?" Yang Yifeng continued to ask.He didn't intend to let Zhou Cheng go.

"Robotics meets MITHA."

"Robot-assisted orthopedic surgery, the robot can automatically plan the surgical path based on the patient's CT image data, and perform precise navigation and positioning.

"The combination of MITHA positioning system and surgical robot technology can improve the accuracy of surgery. The robot can automatically plan the surgical path according to the pre-established bone model and CT image data, and perform precise navigation and positioning to avoid deviations during surgery and improve surgical precision and safety.”

"The combined use of the MITHA positioning system and surgical robot technology can simplify surgical operations. The robot can automatically perform some repetitive and tedious operations, such as cutting and smoothing bones, thereby reducing the workload of surgeons and improving the efficiency of surgery."

"Expansion of application range: The combined use of MITHA positioning system and surgical robot technology can expand its application range. For example, in complex orthopedic surgery, robots can help surgeons to complete more complex operations, such as three-dimensional reconstruction, bone cutting, internal Fixation, etc. This can expand the application range of orthopedic surgery and improve the success rate and safety of surgery.”

"Joint replacement surgery robot: Joint replacement is one of the most commonly used application fields of orthopedic surgery robot technology. The robot can automatically plan the surgical path according to the patient's CT image data, and perform precise navigation and positioning to help the surgeon complete the operation. At present A variety of joint replacement surgical robots have been developed with some success in clinical use."

"At present, if we want to develop and improve the accuracy and stability of MITHA by ourselves, it is impossible for our country to leap forward. In terms of algorithms, there are not so many, and we cannot find a suitable talent pool."

"Therefore, we can only consider such joint applications. Our computer field is still lacking."

"Secondly..."

Half an hour later, Zhou Cheng finished sharing his thoughts!

Yang Yifeng breathed out: "Fang Yun, what do you think of what Zhou Cheng said?"

After Zhou Cheng finished speaking, Fang Yunben let out a sigh of relief.Hearing this, Fang Yun immediately became nervous.at a loss.

However, Fang Yun knows a thing or two about all the technologies that are currently mature, but this thing does not exist in China. Where did Fang Yun know?

Not to mention listening to the heavenly scriptures, but at least they know too little and their knowledge is too narrow.

"Hehe." Fang Yun bluntly replied with a smile.

"I think it's pretty good. At least it clearly explains the limitations of this technology and the current development." Yang Yifeng nodded in approval.

But Zhou Cheng felt very sorry.

This minimally invasive total hip replacement and robot collaboration technology, if there are no talents in the computer field to stand up in advance, this technology will not be displayed. The current so-called minimally invasive total hip replacement is the youth version.

This is the limitation of the times. When Zhou Cheng was in Changshi, he discussed this topic with Director Zhang before, and they could only find a small angle to study it. If it really wants to be carried out on a large scale, it needs to be developed in the computer field. Especially mature things will do.

"Yi Feng, then let me ask you a question about joint surgery." After Zhou Cheng finished his reply, he was ready to reply!

Damn it, his brain was about to blow up during the brainstorm just now, how could Yang Yifeng?

Yang Yifeng was very straightforward: "Don't, brother Zhou Cheng, I admit defeat!"

"You're awesome, okay."

"I will admit defeat if you ask me anything." Yang Yifeng started to play a rogue.

Zhou Cheng looked at Yang Yifeng, a little angry, and wanted to hit someone.

Yang Yifeng accompanied the smiling face, taking off his previous haughty expression and contemptuous tone: "Brother Zhou Cheng, I have to make sure that you are capable of leading our team to prosperity."

"You are this!" Yang Yifeng gave a thumbs up.

There's no way, Zhou Cheng's knowledge reserve is too thick, and he couldn't find it even after searching for faults. If he is asked by Zhou Cheng, he will show his feet sooner or later, so it's better to admit defeat earlier.

Anyway, Yang Yifeng had already looked away and knew his future path.

It is a great fortune to have such a partner in life. It is only the first time that the two meet, and Zhou Cheng wins. In the future, when I really have a problem and need to communicate, I will be able to find someone.

It is a blessing in life to be able to find someone to talk to in an academic field!

So the team leader pk can't go on.
