Chapter 622 Remote Surgery, Delay, 20 milliseconds
"Professor Luo told me to wait for news." Fang Xiao said, "I'll go tell the patient's family."

"go together."

Fang Xiao walked out of the operating room wearing surgical gown. Facing the anxious family members of the patient, Fang Xiao chose to tell the truth.

Or, you can take the 120 ambulance to the provincial capital late at night, but there will definitely be many dangers along the way.

Or, choose remote surgery.

Compared with the long journey of the 120 ambulance to the scene on a dark and windy night, remote surgery is indeed a good solution.

The patient's family had no choice but to agree.

Fang Xiao even felt that the other party didn't even know the risks of remote consultation and surgery.

There was no other way, he could only go down and write the operating room records himself.

After a few days of "training" in Luo Hao's medical team, Fang Xiao had seen Meng Liangren's communication and medical record skills. He could only sigh and try hard to get close to him, but he would never be able to reach that level in his entire life.

"Director Fang, is the patient waiting in the operating room?"

"What else?" Fang Xiao said unhappily.

In the past, he would have directly explained to the patient's family that his technical level was not high enough, given in, and transferred the patient to the provincial capital overnight.

But now...

The more Fang Xiao thought about it, the more annoyed he became.

"Director Fang, aren't you being too cautious?" The director of the vascular department was a little confused.

"Oh." Fang Xiao sighed, but said nothing.

He won't understand anything you say, so it's better not to say anything.

"I heard that thing has a delay, but you still need some time to get used to it at the beginning. Maybe you'll just do the surgery like Mario did." The director of the vascular department said helplessly.

Fang Xiao glared at him.

The director of the vascular department was always worried that he would snatch his surgery away, so he put his hand into his bowl.

This was inevitable. Fang Xiao was also very cautious and never did anything against the rules.

But things were different when Professor Luo came in. Fang Xiao figured out everything in an instant and became more cautious.

The preoperative instructions must be written carefully so that you don't get blamed if something goes wrong.

I don’t care, but Professor Luo does.

"National key scientific research must be implemented. I really envy you."

The director of the vascular department said half-seriously, leaning against the door frame of his office, twirling an uncapped ballpoint pen in his hand, his fingertips swinging in a dangerous arc.

Fang Xiao didn't even raise his head, his fingers typing rapidly on the keyboard. The document on the screen was filled with medical terms and risk disclosure clauses.

He didn't respond, but just said "hmm" lightly, as if he didn't hear it at all.

The director did not leave, but walked in, stood behind Fang Xiao and looked at him for a while, then suddenly laughed: "You wrote this preoperative instruction like a paper, can the family members understand it?"

Fang Xiao's fingers paused.

He stared at the screen, the cursor flashing behind the line "Irreversible vascular embolism may occur during the operation, leading to organ ischemia and necrosis."

It doesn’t matter whether the patient’s family can understand it or not, I will explain it myself when the time comes.

What Fang Xiao was worried about was remote surgery.

The director of the vascular department was still standing next to him, smiling: "Why, you can't write anymore?"

Fang Xiao finally looked up and glanced at him: "How about you come?"

The director of the vascular department waved his hand and took two steps back to the door: "No, this is your project, your contribution."

His tone was light but a little bit sharp. "I'm just curious, if something goes wrong with the surgery tonight, how will you report this 'telemedicine demonstration case'?"

Fang Xiao's fingers stiffened slightly.

Of course he had thought about this possibility - network delays, image transmission freezes, slight errors in remote control by experts... Any mistake in any link could turn this operation into a disaster.

But right now, Fang Xiao didn't have time to argue with him.

"If you have nothing to do," Fang Xiao said calmly, "why don't you go help the nurse check the blood bank's blood supply?"

The director of the vascular department snorted and finally left. The office fell silent, leaving only the sound of keyboard tapping.

Fang Xiao stared at the screen, then suddenly raised his hand to select and delete all the documents.

But Fang Xiao had never been involved in remote surgery, so he had no idea what to pay attention to and didn't even know the key points of the instructions before the operation.

Just as he was pulling his hair out in worry, his cell phone rang.

"Director Fang, Professor Luo said there will be a remote surgery tonight." Meng Liangren did not beat around the bush and went straight to the point, saving countless communication costs.

"Yes, I am..." Fang Xiao's heart moved.

"Before the operation, I was told that there was a template for this side. I made it with Professor Luo some time ago. Can I send it to you now?" Meng Liangren asked.

"!!!" Fang Xiao burst into tears.

"Before leaving, Professor Luo said that the patient should be hospitalized in the orthopedic department. Our interventional department needs to write a consultation record. Can I help you with that?"

"!!!"

Fang Xiao was overjoyed. It turned out that Professor Luo had already prepared an emergency plan and even prepared a document.

As for what Professor Luo's departure meant, Fang Xiao knew it without even asking.

Based on his understanding of Professor Luo Haoluo, Professor Luo would definitely drive over to oversee the first remote surgery.

Well, all my worries disappeared.

"Okay, Lao Meng, send me the document. I'll revise it and communicate with the patient's family to get their signatures."

Soon Meng Liangren sent the file over via WeChat.

Fang Xiao read it through and typed it out word by word.

Director Wang of the Vascular Department sat on the sidelines and watched, leaving the patient on the operating table while the surgeon was typing away. He had never encountered such a situation before.

"Director Fang, you are too relaxed. What does Professor Luo say?"

"It's said that it will take a while. After all, it's the middle of the night. It's not easy over there. They need to transfer a lot of people to the hospital..." Fang Xiao said, sighing.

He didn't tell the truth. Why did Lao Meng tell Director Wang of the Vascular Department what he said?

"The provincial experts are just arrogant. To be honest, I really look down on the provincial experts."

"Da da~" Fang Xiao typed word by word. It was a little slow and a little troublesome, but he was very focused.

"A few years ago, we invited an expert from the province to perform surgery. At first, I didn't know the rules, so my family drove to the high-speed rail station to pick me up. But when the expert saw that it was a regular car, he refused to get in and called a taxi to come to the hospital himself."

"Why? Do you think the car is bad?"

"Yes, they said that only ABB can do it, forget about the others." Director Wang of the Vascular Department laughed, "You said, flying knives are for surgery, why do you need other things?"

"This guy is really arrogant." Fang Xiao continued typing, tap tap tap.

"He didn't want to, but I didn't want to either. If I left Zhang the butcher, would I still have to eat hairy pigs? That's nonsense. Later I thought about changing to another butcher. I agreed to take the high-speed train from there after get off work at around 5 o'clock. It would take an hour and a half, so I would arrive at 7 o'clock and do the surgery at 7:30."

"I ended up waiting until nine o'clock, and they said they would be there soon."

"Huh?" Fang Xiao was startled. "What's going on?"

"After getting off the high-speed train, he went straight to eat Wagyu beef and didn't come to the hospital at all. He ate and drank enough, but luckily he didn't drink. The show didn't start until almost 10 o'clock. Damn, what the hell is going on?"

Director Wang of the Vascular Department was nagging.

Ta-da, Fang Xiao continued typing.

"The key point was that the operation did not go smoothly. He was anxious and cursed while doing it. In the end, I was the one who performed the operation."

"Oh, your luck is really bad." Fang Xiao saw that Wang, the director of the vascular department, was pointing something at something, and immediately hit back, "The experts I contacted are all good. Last time, Professor Luo drove over in the middle of the night after answering the phone call."

"..." Director Wang of the Vascular Department curled his lips and watched Fang Xiao typing.

"We don't need a nurse on the other side, just send a doctor over to do it. Why hasn't it started yet?" asked Director Wang of the Vascular Department.

"I don't know. Maybe they are also trying to save the patient over there. And since it's my first time, Professor Luo suggested that I complete the medical records first."

"Medical records, medical records, can a person be saved if the medical records are well written? Nonsense. Old Fang, do you think that Professor Luo was not sure about it and the screen went black when he turned on the computer?" asked Director Wang of the Vascular Department.

"Hey." Fang Xiao didn't comment.

"It's okay if the screen goes black now, but it will be terrible if it goes black in the middle of a surgery. The domestically produced replacement equipment is not easy to use, just like the drugs purchased through centralized procurement."

"You have to use it. If you don't, you'll never have it. As for MRI, I heard that the one installed by Union Hospital only cost 1000 million yuan, and the quality is pretty good. If domestically produced ones come in, the price of imported Philips or something like that will plummet."

"It costs 40,000 to 50,000 yuan to run the Da Vinci robot once, which is too expensive. European and American companies are really shady. There should be similar products in China, so we can all compete with them together."

"Whether it will be rolled up or not is a matter for the future. The key is that it is not easy to use." Director Wang of the Vascular Department emphasized, "What if something really happens?"

These words were like a knife stabbing Fang Xiao's heart.

In fact, Fang Xiao was also worried about this, but when he thought about it and realized that Professor Luo was on the way, he felt a little relieved.

Time passed by minute by minute, and Director Wang of the Vascular Department kept saying strange things. In particular, the First Hospital of Medical University was slow to connect the surgery, which made him more convinced that there might be a problem.

All 5G is fake, the speed has not increased at all, Director Wang of the Vascular Department thought to himself.

It’s better to use optical fiber than this thing.

But Director Wang of the Vascular Department didn't know how to use fiber optics specifically. Anyway, he had an idea in his mind in the end - remote surgery was not reliable at all and was just a gimmick.

That’s why that side has not been opened for a long time. Let’s see what excuse they find in the end.

It’s a pity that the patient’s rescue time was wasted. It would be better if the patient was sent to the provincial capital by 120 ambulance.

Although there is enough time to rescue pelvic fractures, in the past when there was no interventional surgery, patients had to endure it on their own. If they could endure it, they would live; if they couldn't, it was bad luck.

Director Wang of the Vascular Department became more and more angry the more he thought about it. What kind of remote surgery is this? He really thought 5G could do it.

That's the crap the Chrysanthemum Factory used to cheat for subsidies.

There was a lot of enthusiasm in the past few years, but now there is no movement at all. Some technical up-loaders on the Internet said that there is no difference between using 5g and 4g.

It's just a subsidy scam!

Let's watch the operation later. There was a jam every time it was done, and the delay was very high. The guide wire had already entered the blood vessel, but the image on the other side couldn't be transmitted, and they were still pushing hard in. There was bound to be a big mistake.

You can tell from Fang Xiao's expression.

He wrote a detailed preoperative notice for remote surgery, and included the risks in particular.

You can tell at first glance that Fang Xiao is unsure of himself.

Time passed, and three hours went by.

The patient has already received 10u of red blood cells in the catheterization room, and the high blood pressure is only around 80 mmHg.

Seeing the patient's family members anxious like ants on a hot pan and the catheterization room in chaos, Director Wang of the Vascular Department felt contempt and kept cursing in his heart.

It's just nonsense! !

What is remote surgery? It is just to sell equipment, and finally the equipment is piled in a corner until it is scrapped.

A bunch of moths!
"Director Fang, why haven't you started yet? Why don't you ask again?" Seeing that there was still no news from the other side, Director Wang of the Vascular Department could not help but urge.

Fang Xiao did not move, but just watched the busy figures in the catheterization room without saying a word.

Director Wang of the Vascular Department felt that Fang Xiao was dumbfounded.

This guy has been fooled. The remote surgery is all fake, just a gimmick.

"Director Fang, if surgery is not possible, we should send the patient to the provincial capital."

"The road is bumpy, the fracture ends are changing, and the retroperitoneal hematoma bursts. What should we do?" Fang Xiao replied in a deep voice.

"That's better than waiting to die here!"

"Wait a moment, Professor Luo..." Fang Xiao said, his voice gradually becoming low and vague.

Professor Luo?
Director Wang of the Vascular Department thought of the young expert from the First Hospital of Medical University who had always told Fang Xiao not to make irresponsible remarks.

Poke?

Is that what his family said to the surgeon? Can't they be a little more respectful and tell him not to operate recklessly, or the endothelium of the blood vessels will be torn?

Director Wang of the Vascular Department has never had a very good impression of Professor Luo, but Fang Xiao and Professor Luo get along very well, and the previous patient has recovered and been discharged from the hospital, so Director Wang is reluctant to say much.

Seeing this situation, Director Wang of the Vascular Department felt annoyed.

"Director Fang, you are killing people by doing this!"

"Huh? Director Fang can also kill people?" a voice came from behind.

"Professor Luo!" Fang Xiao turned around and was also stunned for a moment, then became excited, "Why did you come in by yourself?"

"The door of your locker room is open." Luo Hao smiled and rubbed his hands. "I wanted to call you. If you see the door is open, just change your clothes and come in."

"What's the matter, Director Fang, did you kill someone?" Luo Hao teased while turning on the remote surgery machine.

"I did several surgical trainings after the last debugging, three times," Fang Xiao quickly added.

Director Wang of the Vascular Department looked at Luo Hao in silence.

He vaguely felt that he was wrong.

The aura that Luo Hao carried was getting stronger and stronger. The last time he came, he was faintly emitting a milky white light. This time the light was even stronger, and Director Wang felt that he could not open his eyes because of the dazzling light.

"Director Yuan, I'm here." Luo Hao connected the video. "I'm sorry, this is my first remote surgery. It would be better if there is someone watching over me."

"It's okay. I've seen the patient's X-rays. The operation is not difficult." Yuan Xiaoli said, "Then shall I start?"

"Wait for me to change my clothes and go in." Luo Hao left his phone behind and went to wash his hands, put on a lead suit and go into surgery.

Isn't this just taking off your pants to fart?

Director Wang of the Vascular Department complained in his heart.

Even though he knew that Luo Hao was doing a remote surgery for the first time, he rushed here in person to avoid network delays and other issues. If there was anything, he would go directly there.

But Director Wang of the Vascular Department still felt resentful in his heart.

But the thoughts of complaining became weaker and weaker, and finally almost disappeared.

He didn't realize that his fear had become so strong that even his complaints quickly dissipated.

Director Wang of the Vascular Department has seen such people, but generally speaking, they are junior doctors in clinical practice. Anyone with a slightly higher level of ability must show strength in front of others and not let others look down on them.

This is also commonly known as face.

But Professor Luo didn't think so much. There was still snow on the road outside, so he drove over for more than three hours just to be a substitute.

This is too much.

Just as Director Wang of the Vascular Department was daydreaming, the airtight lead door closed and the operation began.

"Professor Luo, the ping value is 22." Fang Xiao pressed the intercom to report.

"Okay, very good." Luo Hao was wearing armor and standing in the operating room, his eyes fixed on the screen opposite.

He does punctures and arterial sheath placement. Watching the robotic arm moving in an orderly manner, with a faint rustling sound, Luo Hao's mouth curled up, and the arc became more and more obvious.

This is the prototype of an unmanned hospital.

Surgery does not necessarily have to be performed by a human.

How long does it take to train a doctor? Not to mention myself, for someone like Yuan Xiaoli, it takes at least 10 years, and he has to perform countless surgeries.

Who will bear the consequences of a failed operation?

Even if they are trained, they will be treated like slaves and sleep in the catheterization room every day.

What if it's a machine?
There are films before the operation, and AI is used for analysis, decision-making, and surgery. The patient is calm, indifferent, and cruel. There is no fatigue or fluctuation in level like a human being. It is like turning on [Calm Fury] and [Flow], and the patient is always invincible and maintains the top level of surgery.

And this is just the first step.

It will eventually work out, Luo Hao thought to himself.

The latency is very low, around 20 milliseconds, which is about the same as when playing games.

As for worrying about network problems, Luo Hao thought it was a no-brainer.

Boss Chai once told a story from the past - when the hospital purchased ventilators in bulk, some people questioned what would happen if there was a power outage.

power failure?

Dare to cut off the power in the hospital now?!
Backup power supply and special protection have been quietly ingrained into our bones.

Luo Hao has been involved in clinical work for ten years, ever since he went to college. During this period, he has never encountered a power outage.

So network delay is not a big deal to Luo Hao and it can always be overcome.

In the future, there will even be a remote operating system with a trainer mode, where one person performs surgery while a teacher is watching and other students are also simulating the operation.

It's all possible.

Yuan Xiaoli, who was in the provincial capital, operated the guide wire for superselection. Several difficult points were solved in one go, and the delay was almost zero.

Although it was remotely operated, it felt like he was standing in front of Luo Hao.

The microcatheter is introduced and angiography begins.

After determining the bleeding point, Yuan Xiaoli began embolization to block the blood vessels punctured by the bone stump.

One stick, two sticks, three sticks...

After one hour and twenty minutes, all five blood vessels were blocked.

At this time, the patient's blood pressure also returned to 120 mmHg.

Luo Hao smiled, turned around to leave, but came back immediately.

This is not home, there is no robot pressing to stop the bleeding.

Luo Hao put on gloves again and did some finishing work after the operation was completed.

Yuan Xiaoli certainly doesn't do similar work, and the robotic arm also lacks some functions. After all, the initial puncture belongs to puncture technology, which is a different technical route from catheter technology.

If a separate set of surgery is to be done, it will take some time, and when performing the surgery in the First Hospital of Medical University, Luo Hao's only requirement is not to wear a lead suit.

Remote operation and local doctors can complete the preliminary steps are not too high a requirement.

Luo Hao did not aim too high.

Everyone wants to achieve their goal in one step, but the conditions must be met.

The robotic arm pulled out the guide wire and catheter, and Luo Hao began to complete the next steps.

The airtight lead door opened, and Director Wang of the Vascular Department pushed Fang Xiao aside and trotted in.

"Professor Luo, I'll do it."

"Director Wang, right?" Luo Hao smiled.

"Yes, you can just call me Xiao Wang." Director Wang of the Vascular Department put on gloves and prepared to press. "You still need to watch the operation process and communicate with the First Hospital of Medical University. You are busy. Leave this small matter to me."

Luo Hao just heard that this person seemed to be arguing with Fang Xiao, but he didn't expect him to kneel down so quickly.

"That's troublesome." Luo Hao turned around and walked off the stage.

Originally, this job was done by robots, so Luo Hao didn't care.

Fang Xiao was stunned. Was Director Wang from the Vascular Department so unrestrained that he just pressed to stop the bleeding?

"Director Fang, how do you feel?" Luo Hao asked.

"Yes, the latency has always been low. To be honest, Professor Luo, I don't think remote surgery is very reliable, but that was what I thought before."

"It's okay, not unreliable."

"Yes, yes, with this example, it will be easier for me to communicate with the patient."

Luo Hao smiled.

"I thought you would definitely start at the Donglian Mine."

"Well, the tube ball of the machine broke recently and it's being repaired. We owe the manufacturer a certain amount of money, so it has been delayed. It has nothing to do with remote surgery." Luo Hao explained.

Fang Xiao Khan.

Luo Hao came to the operating table and found the video of the operation.

He increased the speed of the operation to 5 times, watched the whole process, and expressed satisfaction.

This is basically equivalent to Yuan Xiaoli performing the surgery in person. If he didn't know about remote surgery, even Luo Hao wouldn't be able to tell the difference.

A delay of about 20 milliseconds is almost equivalent to nothing for humans, as it is almost instantaneous with the heart, eyes, and hands.

"Professor Luo, this is also..." Fang Xiao sighed.

Although I have communicated with Luo Hao many times, talking about it a thousand times is not as good as seeing it with my own eyes once.

Fang Xiao was so shocked that he was speechless.

"You didn't expect it, did you?" Luo Hao said with a smile. "It has almost become a daily routine for experts from West China to perform remote surgeries on Sarah's patients."

"You know Sarah, Gao Yuan, she's dizzy when she goes up there, and whether she can do it or not is another matter. Even if she tries to do it, no one can guarantee that there won't be any problems. It's good enough if the surgeon can perform at half of his level under hypoxic conditions."

“I didn’t expect that the first one to start the project would be West China,” Fang Xiao said with emotion.

"Huaxi is very strong, and there are other responsibilities on that side."

"responsibility?"

"There was a Tibetan class at West China Medical College in the past, and it has been many years..." Luo Hao did not explain it in detail. He also heard some things from the old West China people of Teacher Pan's generation.

Things like Han students fighting with students from the Tibetan class.

But as the knowledge was passed down from generation to generation, they gradually accepted the customs and habits of the Sichuan and Chongqing regions. In order to overcome altitude sickness and improve the quality of medical care there, remote surgery was even the first to be carried out.

"In fact, there is not much need for us."

"No, Professor Luo, it's too big!" Fang Xiao quickly interrupted Luo Hao, "From now on, I'll leave all my surgeries to Professor Luo."
