godfather of surgery

Chapter 975 Tetris

The operating theater demonstration room was filled with doctors in the middle of the night. The blockbuster finally came to an end, but everyone still felt a little unsatisfied.

In other people's robotic surgeries, the two robotic arms look like two human hands, cooperating with each other to perform the surgery. In fact, the essence is still the human operation mode. No matter how you look at it, it is still a person performing the surgery. You can tell at a glance that there is a person behind the scenes controlling the two robotic arms.

However, Professor Yang's robotic surgery today gave people a strong feeling: this was not a human performing the surgery, but rather a real intelligent robot performing the surgery, because the coordinated operation of several robotic arms made it impossible to associate the operation with a human being behind the scenes. The various operations of the three robotic arms presented a strong mechanical aesthetic.

Of course, the term "multi-arm thinking" is also deeply imprinted in everyone's mind, because just now when Director Fang was explaining the operation in the demonstration room, he mentioned the concept of multi-arm thinking from time to time. As the term for the core technology of Yang Ping's robotic surgery, it naturally spread quickly.

After observing the operation tonight, Director Fang kept repeating the words "multi-arm thinking" in his mind, as if he had realized something profound. Multi-arm thinking, how could I possibly acquire multi-arm thinking when I only have two hands?

Director Fang spread out his hands, and his mind was confused for a moment. Isn't all human operation based on two hands? So how to train multi-arm operation? This is completely impossible to train.

After the operation, Ou Lianfeng was sent to the ICU with ECMO. Postoperative monitoring for this type of operation is much more convenient in the ICU, and ordinary wards are unable to provide postoperative monitoring for him.

After the operation, Yang Ping took a nap in the department. It would be almost dawn soon, and he didn't want to go back at this time to disturb his family. Xiao Su was in confinement during this period, and it was quite hard for her, so he had to ensure that she had a good sleep.

Lying on the bed in the duty room, Yang Ping entered the system space and used the time inside to think about the problem of surgical robots. The current Da Vinci surgical robot can be said to be the most advanced and mature robot in the world, but it can only simulate human arm operations. In fact, this operation mode is extremely backward and inefficient. The machine should have its own mode.

On the contrary, some computer games and mobile games that have higher operating requirements have broken through the two-arm mode and replaced it with a new operating mode based on keyboard and mobile phone screen. You can imagine that if these games still use the simple two-arm operation mode, then the richness, diversity, sophistication and instantaneity of the game operation will definitely be greatly restricted.

Ruixing Medical is also investing heavily in the development of surgical robots. Yang Ping now has a lot of ideas in his mind. The new generation of surgical robots must move away from the two-arm operation mode and use a new operation mode to replace this old mode, making the operation rich, diverse, refined, and instantaneous. One operating panel can be used to operate multiple robotic arms at the same time, breaking down the movements into some basic movements, and then combining the basic movements into countless advanced movements.

Only in this way can ordinary doctors truly control several robotic arms at the same time to complete a surgical step. Compared with the traditional two-arm operation mode, it not only improves efficiency, but also improves operation quality, lowers the operation threshold, and makes actions that were previously difficult or impossible to complete become extremely easy.

After thinking about how to control the surgical robot, some concepts in Yang Ping's mind became clear and he fell asleep peacefully. However, he didn't sleep for long and had to get up again in the morning.

The next morning, Yang Ping went to the ICU for rounds. Director He from the Department of Thoracic Surgery and Director Fang from the Department of General Surgery were already waiting in the ICU. Director He didn't want to call Yang Ping too early, fearing that Yang Ping wanted to sleep a little longer. However, he didn't know when Yang Ping would come for rounds, and was afraid of missing the first post-operative rounds, so he came to the ICU early to wait.

Director Fang of the General Surgery Department simply slept in the duty room of the ICU and instructed the doctor on duty in the ICU to notify him if Yang Ping came to make rounds.

Now Yang Ping came to check on the ward, Director He went to wait at the door, and Director Fang was eating breakfast. He held three chopsticks in front of himself, thinking about how to use these three chopsticks to eat today's breakfast. After thinking about it, he realized that he only had two hands, not three hands, and three chopsticks were completely redundant, because the only two chopsticks he could really use were.

Similarly, the da Vinci surgical robot has four robotic arms, one of which acts as a lens, and the other three are like the three chopsticks in front of you. People only have two hands, and the machine has only two main controllers, and only two of the robotic arms can be controlled. The other one is in an idle state unless the control is switched. However, no matter how it is switched, it is still a problem of three bottles and two caps, and there is always one robotic arm on standby.

The doctor in the ICU saw Director Fang staring at the three chopsticks in a daze and reminded him: "Professor Yang is here to make rounds."

Director Fang nodded but didn't react much.

"Professor Yang is here to check on the ward!"

"Oh!"

Director Fang woke up immediately, without even having breakfast, and immediately put on isolation clothing and went to the ward to follow Yang Ping in making rounds. Ou Lianfeng's vital signs were very stable after the operation, and Yang Ping decided to remove the ECMO 24 hours after the operation and let the implanted lungs start working. The sooner they can start working, the faster they can recover.

After the rounds, Director Fang secretly asked Yang Ping: "Professor Yang, you mentioned the concept of multi-arm operation several times. I have been thinking about how to control three chopsticks with two hands. I always think that two chopsticks are the best solution. Three chopsticks are completely redundant. Not only are they useless, they are also a burden. At most, they are just a substitute."

"Can you play computer games?" Yang Ping said after thinking for a while.

Director Fang touched the back of his head and said puzzledly: "I don't know how to play games. I have never played this thing before."

Professor Yang suddenly mentioned computer games. Could the surgery be related to computer games?
"If I didn't play computer games, it would be hard to explain." Yang Ping was a little embarrassed.

Because as long as people operate it, they definitely have only two hands, but the control method of the Da Vinci robot and computer games just reflects the difference. The Da Vinci surgical robot's manipulation from the intermediate to the terminal action still simulates the operation of human arms.

The operating medium of computer games is keyboard and mouse. Although it is also operated by two hands, the keyboard and mouse to the final action have deviated from the human two-arm mode and are completely a computer mode. Yang Ping's multi-arm mode refers to the transmission from the operating medium to the final action. This operating transmission chain must have the surgical robot's own mode, rather than the two-arm mode.

"But I can play Tetris," Director Fang immediately added.

Tetris is also a game, it is both a computer game and a mobile game. Can't it be played on both computers and mobile phones?

"How was your fun?" Yang Ping asked again.

"It's just the level of knowing how to play." Director Fang answered truthfully.

Yang Ping immediately said, "Well, take an hour every day this week to play Tetris. Come back to me in a week and I'll tell you what the multi-arm mode is. In fact, the multi-arm mode cannot be called the multi-arm mode, it should be called the machine mode. The term multi-arm mode is used only to distinguish it from the two-arm mode, because the machine never uses the two-hand mode when transmitting actions."

"Play Tetris for a week?" Director Fang suspected that he had heard it wrong.

Yang Ping nodded: "Yes, are you in trouble?"

"No, no, I'll just play for a week."

"Professor Yang, I can play King of Glory for two hours every day!"

Director He Xiangjun said proudly.

"You can play King of Glory? Then come to me directly later and I will explain the multi-arm mode to you." Yang Ping said to Director He.

Director Fang was completely confused. It turned out that He Xiangjun's ability to play King of Glory actually gave him an advantage and he could go to receive classes directly. He, on the other hand, still had to play Tetris for a week.
