Chapter 447 The leader pk is carried out...! (Please subscribe)
"There's no emergency now, right? Let's start with the class now?" After Yang Yifeng and Zhou Cheng had dinner, An Ruo and Liu Shiyu made an appointment to go shopping together.
Zhou Chengcheng and Yang Yifeng came to the lounge of the emergency department, and took Fang Yun with them to hold a formal meeting of the prototype team!
However, Yang Yifeng proposed a battle, that is, now everyone is an employee in the same unit, and when working in the future, they must also be in the same environment.
It is no longer the student stage it was before.
At this time, during work, academic activities and experimental teams, who will take the lead must be planned and agreed in advance.
The agreed method is very simple, that is, a face-to-face academic battle, with no preparation time in advance.
Hearing this, Fang Yun quickly said: "Teacher Zhou, Brother Yifeng, can you wait a moment while I find some paper and take notes?"
Fang Yun was afraid that he would not be able to keep up with Zhou Cheng and Yang Yifeng's thinking and would be confused when the time came, so he could go back and practice for a while.
"Then tell me, how do we start and how do we determine a better direction for discussion?" Zhou Cheng thought Yang Yifeng's suggestion was good.
Moreover, Zhou Cheng rarely went head-to-head with Yang Yifeng. In the past, Yang Yifeng always followed him. Now Yang Yifeng wants to stand up and take charge, which Zhou Cheng can understand.
Moreover, Zhou Cheng also supports the current method of ‘fighting’, which is to compete for knowledge reserves.
Indeed, asking Yang Yifeng to do things for him without any evidence is not a good idea.
"You and I are both trauma surgeons. We won't discuss foot and ankle, trauma, surgery, etc. in detail in trauma surgery. Let's choose an orthopedic topic other than trauma surgery."
"One of the more mature surgeries now is total hip replacement, and there is a kind of MITHA for total hip replacement. I will ask you about your understanding of this surgery, its development prospects, etc., and then you will ask me a similar question."
"Let Fang Yun be the judge. The decision is final. If you lose, you will assist me in my work in the future, whether it is clinical or scientific research. It will be the same if I lose!"
"That's fair, it just depends on the knowledge base." Yang Yifeng said very formally.
"Okay!" Zhou Cheng agreed without hesitation.
Fang Yun was not given time to take notes at all. Fang Yun's knowledge reserve was relatively small. It took him a while to realize 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 also feels that it is of little significance, because total hip replacement itself is already very mature.
Zhou Cheng thought for fifteen seconds and organized his words slightly: "MITHA is a new technology used in total hip replacement surgery. Minimally invasive is its concept. Compared with traditional surgical techniques, it can reduce the number of surgical procedures.
Post-operative pain, shortened recovery period and reduced risk of complications.”
"The main features of MITHA are smaller surgical incisions and more sophisticated tools and instruments. This results in patients having less postoperative pain, faster recovery, and requiring a shorter hospital stay. Since MITHA causes less trauma to soft tissues,
Postoperative incisions and scars are also smaller, which is also good for the patient’s appearance and how they feel about their body.”
"The surgical instruments used by MITHA are more sophisticated, and the difficulty and risk of the operation will increase, requiring a higher level of technology and experience. In addition, the cost of MITHA is relatively high, which may increase the burden of medical expenses."
"Therefore, it is somewhat difficult to apply it widely in China." Zhou Cheng first started the topic by looking at the overall situation.
Yang Yifeng was naturally dissatisfied with such depth: "You have to make it clear about MITHA's challenges and limitations, and you can't fool them. What are the basic skills of MITHA?!"
Although the questions Yang Yifeng gave are vague, they are the most primitive part.
Zhou Cheng answered without hesitation: "Minimally invasive surgical instruments: including micro hammers, drills, bone saws, rongeurs, bone drills, bone expanders, etc. Stereotaxic system: used to accurately position surgical instruments and surgical sites to improve surgery.
accuracy."
"Special hip replacement prostheses. These are original materials."
"MITHA usually performs surgery 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 entire surgical process.
Waste of everyone's time.
"Limitations: The instruments used in MITHA surgery are more sophisticated, and the difficulty and risk of the 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 will be limited. This may affect the accuracy and safety of the surgery. In addition, the 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 medical treatment for patients is relatively high."
Yang Yifeng nodded again, thought about Zhou Cheng's answer and the omitted parts for a while, and felt that it was almost enough. However, this answer still did not meet Yang Yifeng's requirements for Zhou Cheng.
At least it didn't surprise him, it was just a simple conceptual understanding.
Fang Yun was a little confused, with bright and complicated eyes. He might be excited because he felt that he could learn more, but he was also disappointed because he had learned less!
"What is 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 the cost can be reduced?"
Zhou Cheng frowned slightly and began to quickly mobilize his knowledge reserves. If he had not experienced simulations for a long time, he might not have been able to answer: "In the late 1980s, computer navigation technology began to be used to assist hip replacement surgeries. In the early days,
The positioning system uses photoelectric probes for positioning, but its positioning accuracy and stability are poor.
"In the 1990s, positioning systems using optical sensors for positioning appeared, and their accuracy and stability were significantly improved.
"At the beginning of the 21st century, magnetic positioning systems began to be used in hip replacement surgeries. 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 robotic technology with the MITHA positioning system and develop some hip replacement robots with autonomous control functions. These robots can achieve more precise hip replacement surgeries, but their cost and technical difficulty are relatively high.
High, further research and improvement are still needed.
"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."
"You should explain accuracy and stability separately." Yang Yifeng increased the difficulty.
As long as any problem continues to be deepened, it will enter an unsolvable level. It is not necessarily unsolvable, but it will definitely touch the edge of the knowledge system!
This is an academic battle!
"About accuracy!"
"Improvement of sensor accuracy: The sensor used in the MITHA positioning system is one of the key factors in positioning accuracy. By improving the design and manufacturing process of the sensor, the accuracy and stability of the sensor are improved. For example, new sensors use ultrasonic waves for position measurement,
Higher positioning accuracy can be achieved.”
"Improvement of positioning algorithm: The MITHA positioning system uses algorithms to convert data collected by sensors into position information required for surgery. Currently, researchers mainly improve the positioning accuracy of the MITHA positioning system by improving the positioning algorithm. For example, using neural network algorithms and depth
Learning algorithm can improve the accuracy of identifying the position of the pelvis and femur."
"Application of three-dimensional reconstruction technology: Three-dimensional reconstruction technology can reconstruct multiple two-dimensional images into a three-dimensional model, improving the accuracy of identifying the position of the pelvis and femur during surgery. For example: applying three-dimensional reconstruction technology to the MITHA positioning system to improve positioning
Accuracy.”
"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 join forces with MITHA."
“About stability!”
"Improvements in robot control technology, adding algorithms, already explained above."
"The hardware of the MITHA positioning system is one of the key factors in 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 interaction interface: The human-computer interaction 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, thereby discovering problems in advance and making 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. His current surgical skills are excellent, but his knowledge reserve and scientific research capabilities are still a little lacking.
But the above is only the current research progress, not Zhou Cheng’s own ideas.
"If we want to widely apply it to clinical practice in my country, we must develop it ourselves. In your opinion, what are the indicators that are most likely to realize the mature application of MITHA? How to develop it?" Yang Yifeng continued to ask. He did not intend to let Zhou Cheng go. .
“Robotics meets MITHA.”
"Robot-assisted orthopedic surgery, the robot can automatically plan the surgical path and perform precise navigation and positioning based on the patient's CT image data.
"The combined use of MITHA positioning system and surgical robot technology can improve the accuracy of surgery. The robot can automatically plan the surgical path based on the pre-established bone model and CT image data, and conduct 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, tedious operations, such as cutting and grinding bones, thereby reducing the surgeon's workload and improving the efficiency of the operation."
"Expansion of application scope: The combined use of MITHA positioning system and surgical robot technology can expand its application scope. For example, in complex orthopedic surgeries, robots can help surgeons complete more complex operations, such as three-dimensional reconstruction, bone cutting, internal
Fixation, etc. This can expand the application scope of orthopedic surgery and improve the success rate and safety of surgery."
"Joint replacement surgical robot: Joint replacement is one of the most commonly used application fields of orthopedic surgical robot technology. The robot can automatically plan the surgical path based on the patient's CT image data, and perform precise navigation and positioning to help the surgeon complete the operation. Currently
A variety of joint replacement surgical robots have been launched and have achieved certain success in clinical applications."
"Currently, if we are asked to develop on our own to improve the accuracy and stability of MITHA, it is impossible for our country to leap forward. In terms of algorithms, we do not have 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 took a breath: "Fang Yun, what do you think Zhou Cheng said?"
After Zhou Cheng finished speaking, Fang Yunben let out a sigh of relief. After hearing this, Fang Yun immediately became nervous and at a loss.
Fang Yun knew a little bit about all the technologies that were currently mature, but this thing was not available in China. Where did Fang Yun know where to go?
I don’t mean to say that I have read the book from heaven, but at least my understanding is too little and my knowledge is too narrow.
"Haha." Fang Yun replied with a smile bluntly.
"I think the explanation was pretty good. At least it clearly explained the limitations of this technology and the current development situation." Yang Yifeng nodded in approval.
But Zhou Cheng felt very sorry.
This collaborative technology of minimally invasive total hip replacement and robots will not be demonstrated if there are no talents in the computer field who step forward in advance. The current so-called minimally invasive total hip replacement is a youth version.
This is the limitation of the times. When Zhou Cheng was in Changshi, he discussed this topic with Director Zhang before. They could only find a small angle to study it. If it really needs to be carried out on a large scale, it would have to be done in the computer field.
Only something extremely mature will do.
"Yi Feng, let me also 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 explode from the brainstorm just now, how could Yang Yifeng do it?
Yang Yifeng said simply: "No, Brother Zhou Cheng, I surrender!"
"You're awesome, okay."
"I will admit defeat no matter what you ask me." Yang Yifeng started acting rogue.
Zhou Cheng looked at Yang Yifeng, a little angry and wanted to hit him.
Yang Yifeng smiled with his face, taking off his previous arrogant expression and contemptuous tone: "Brother Zhou Cheng, I also want to make sure that you are capable of leading our team to prosperity."
"This is you!" Yang Yifeng gave a thumbs up.
There is no way, Zhou Cheng's knowledge reserve is too deep, and he has not found any faults. If he is asked by Zhou Cheng, his flaws will be revealed sooner or later, so he might as well admit defeat earlier.
Anyway, Yang Yifeng had already looked away and knew his future path.
It is a great blessing in life to have such a partner. It was just the first time that the two of them met. Zhou Cheng won the victory. In the future, when I really have problems and need to communicate, I can find someone.
It is a blessing in life to find someone to talk to in the academic field!
