"Zheng, take a look at the recording of the remote surgery you performed yesterday." After Dr. Charles admired his surgery, he said directly to Zheng Ren.
After all, an appendectomy, no matter how perfect it is, can only prove the applicability of this machine. Dr. Charles is concerned about the feasibility of using this machine to perform difficult surgeries, such as the surgical treatment of Gaucher's disease.
How difficult the operation is can be clearly understood just by analyzing the result of removing a 6.2 kilogram spleen.
Spleen, 6.2 kilograms. It is indeed strange to use weight units to measure the difficulty of the operation, but this is the fact.
Dr. Charles understands the difficulty of Gaucher's disease surgery very well. In addition, the patient is a pregnant woman who needs to have a caesarean section and remove most of the spleen, so Dr. Charles can't wait to watch the recording of the operation.
"Doctor, Su Yun and I worked together to complete the major splenectomy surgery on the 3D printed simulator, and the real patient was completed by our other doctors in Imperial City." Zheng Ren said again.
"I know, Zheng, you just said this. Come on, let me see how you use a robotic arm to perform Gaucher's disease surgery. Whether it's a simulated surgery on a patient or a simulator." Dr. Charles continued urge.
While he was talking, the projection of the surgical recording appeared on the big screen, just like on the assembly line of a factory. The four robotic arms were working in silent cooperation, and the surgical recording began.
Dr. Charles watched with great interest. Unlike when he personally entered the operating room to complete an appendectomy, standing below he could see the overall situation and see more details.
The sterilized, robotic arm holds the scalpel in a pen-holding manner, as if it has a soul, leaving a just-right incision on the 3D printed simulator.
Then another robotic arm began to wipe the blood stains with skillful and gentle movements, and then used electric cautery to stop the bleeding.
The coordination between the two people and the four robotic arms was so wonderful. If it weren't for the full metallic texture and the feeling of a steam industry like an assembly line, no one would think that this time it was a job that a thick robotic arm could complete.
Especially Dr. Charles, who had just undergone an operation, could better understand the difficulties of these operations.
But after watching it for a few minutes, Dr. Charles frowned and stared at the screen. Soon he asked doubtfully, "Zheng, why do I feel like you didn't do the surgery yourself?"
"Doctor, it is indeed the robotic arm that I operate." Zheng Ren said.
"There is nothing wrong with the surgery, but the operation is too unfamiliar, and there is no smooth beauty at all. I just tried the operation of the robotic arm, and the feel is still very important. If it weren't for your confirmation, I would have thought that someone else was doing the surgery. You stand aside and guide,” Dr. Charles said.
Zheng Ren understood what Dr. Charles meant at this time.
Some of the doctors observing the operation also noticed this, and they were whispering among themselves.
If Zheng Ren hadn't launched a live broadcast of the surgery in Xinglin Garden, his surgical skills would have been recognized by everyone. I am afraid that by this time, the voice of doubt would have drowned Zheng Ren like a vast ocean.
"Doctor, you misunderstood." Zheng Ren said with a smile, "This is a remote surgery. Because the network signal in Stockholm is average, the network speed is too slow, and there is network delay, so the operation looks a bit jerky. But during the operation, I and I Su Yun tried his best to overcome the high delay and avoid mistakes during the operation."
Zheng Ren paused and then added, "The doctor who performed the surgery in Imperial City was also very cautious. He only used our surgery as a reference and made various subtle adjustments based on the intraoperative conditions at that time."
"Network delay." Dr. Charles said softly.
"Remote surgery is based on two points, one is rooted in the sensitivity of the robotic arm, and the other is rooted in the network transmission speed." Zheng Rendao.
"Dr. Charles, without 5G network, remote surgery is nonsense." Su Yun added with his eyes open to tell lies.
Su Yun is best at this kind of half-right and half-wrong talk, but he is not as meticulous as Zheng Ren. In fact, 4G optical fiber is enough, but 5G can go one step further and use wireless signals. For hospitals, fixing warehouses and fixing optical fibers is a small matter.
Dr. Charles was noncommittal and watched the operation continue seriously.
After hearing the explanations from Zheng Ren and Dr. Charles, the doubts of other doctors also disappeared. Is it a network problem? The rollout of 5G networks involves larger-level issues that doctors cannot participate in.
Everyone watched the operation in silence.
"Zheng, how much is the delay?" Dr. Charles suddenly asked.
"It fluctuates between 80-110MS, and stays around 100ms most of the time." Zheng Rendao.
"Or fluctuating value?" Dr. Charles asked a very "silly" question. After asking, he also responded.
The network transmission speed will definitely not be a constant value. In this case, the operation is still a difficult operation like Gaucher's disease!
Dr. Charles was silent.
In his eyes, the originally unsmooth and unsightly surgical process took on another meaning.
There was no sound in the recording of the operation. Everyone in the venue was watching the operation with full concentration, and it was difficult to hear even the sound of breathing.
All the eyes of the audience were attracted by the assembly line-like robotic arm.
Even with a delay of 100ms, even when performing a difficult surgical operation for Gaucher's disease, the almost perfect cooperation of the four robotic arms mesmerized everyone.
Is this the template for future surgeries? With the robotic arm, the 3D printed model, and this brave attempt, is it still far away from custom-made surgical chips for everyone
Such an idea floated in Dr. Charles's mind.
He didn't think about remote surgery. If it were possible, this surgical model would inevitably evolve into an unmanned era.
Unmanned surgery and unmanned driving are two different concepts. But the patient information is sent to the hospital by post, and the surgeon performs surgery on the 3D printed manikin, then makes a chip and completes the surgery through the smart chip...
This is not a fantasy!
Zheng has taken the first step, and even Dr. Charles cannot tell how many changes will follow.
He looked at it, unable to contain the excitement in his heart, and his fingers trembled slightly.
When I first became a doctor, I never dared to think about the concept of unmanned surgery. However, at this time, unmanned surgery has become a possibility!
But then Dr. Charles no longer thought about what might happen in the future. He concentrated on watching the surgical process on the "assembly line." The surgery under 100ms delay is still accurate and quite beautiful!
Until the end of the operation, Dr. Charles turned around, opened his arms, and hugged Zheng Ren.
"Zheng, you created an era!"
