In the operating room.

Sun Taian looked at the patient in front of him and took a deep breath.

Next, he has a daunting task.

One step cannot be wrong.

But compared with the operation performed on monkeys, it is actually simpler to perform on humans.

Because the bones and nerves of humans are larger than those of monkeys.

That way, he doesn't have to worry too much.

But at the same time, because this is a clinical practice on human body, more care must be taken.

However, Sun Taian's mentality soon stabilized.

He has done countless surgeries, all involving nerves. Isn't this simple surgery easy?

What's more, thinking that once the operation is successful, a part of the body will be transformed into a mechanical person, and he will be born under his hands. He looks forward to that moment even more, and believes that his name will be engraved in the medical history book by then.

"Is that Zhao Guoping? Please relax for a while, and keep still during the operation later."

"Don't worry, doctor, I know it well." Zhao Guoping nodded. It was related to his life for the rest of his life, so he couldn't take it seriously.

Even if the doctor asked him to knock him out, he would probably be willing to accept it.

"Um."

Sun Tai'an nodded slightly, observed for a while at last, and then said: "The subject is emotionally stable, and the first phase clinical trial of the neural control exoskeleton begins."

There is surveillance in the operating room, and the relevant personnel are watching the situation. Sun Tai'an's words are also for them. In addition, there are some high-level personnel observing the live broadcast.

There are quite a lot of people who pay attention to this clinical trial.

Of course, Zhao Guoping also agreed to the live broadcast, which could bring him another 10,000 yuan in remuneration.

The video of this operation will become a tutorial video of this operation in the future.

Sun Tai'an pulled down the glove, and then tightened it on his wrist with a "snap".

The assistant next to him came up to take off Sun Tai'an's shirt, leaving only a small piece of shoulder that was not connected by two limbs.

Two severed arms, this time, were to be connected to his right arm.

First the surface is disinfected and then anesthetized.

Then, move the knife, move the knife from the center of the broken arm, and cut a hole about four centimeters.

Then, just as in the previous operation on the monkey, you need to find the remaining arm bone.

That arm bone has a relatively large cross-sectional area and a long diameter, as you can tell by touching your arm.

Moreover, Zhao Guoping himself is relatively strong, almost 1.78 meters, so his arm bones are relatively thick.

However, once the bone is found, it is not possible to proceed directly to the next step, but the incision needs to be processed to facilitate the connection of the bone arm connector to it.

This time, Guge developed a new connection scheme to make the connection stronger.

Because human bones are bigger, a large screw is driven in from the middle, and then three small screws are driven in from the side.

This can increase the fixing force.

Zhao Guoping's incision was quickly processed, and the incision was fixed with a fixed clip to expose the bones inside. Afterwards, Guge took out the medical electric drill, replaced it with the corresponding drill bit, and started drilling.

The center hole appears, and then the screws and nuts are screwed in, and then a circular metal sheet is used. The hole in the middle of the metal sheet is just enough to fit a large nut, and then there are three small holes on the side, which are used to drive in the other three screws and nuts. Avoid positional deviations.

Lying on the hospital bed, Zhao Guoping heard the sound of the medical electric drill beside him. Although he had seen this kind of thing before when he was a moth, but this time he was directly moving against his arm bone, and he was still a little flustered.

But soon, he relaxed again.

Anyway, that bone was going to be useless in the first place, and now that it finally has a chance to recover, why do you care about such things?

Thinking about his parents, they are almost seventy years old, and he has been sorry to them for so many years, and when he regains his hands, he will not have to worry about him in their old age.

At this time, an assistant next to him probably noticed his fluctuating emotions, and he took the initiative to ask: "I heard that you won the championship in your Yunnan Province Paralympic Games before?"

It is also their duty to stabilize the patient's emotions by chatting with the patient.

Zhao Guoping remained motionless, and replied with a smile, "Yes, if I hadn't been older, I might have been able to compete in the Paralympics last year."

The assistant smiled and said, "Haha, that's amazing, but I don't know if you will be considered a disabled person in the future."

Zhao Guoping was taken aback for a moment, then remembered, if the operation was successful, wouldn't he have arms and legs? He is no different from ordinary people, so is he still a disabled person?

He thought for a while, then suddenly said: "Could there be a sports meeting for cyborgs like us in the future?"

Cyborg, what a sci-fi word.

The assistant was about to speak, but Sun Tai'an joined their conversation at this time.

He had installed all the nuts on Zhao Guoping at this time, and the next step was to pick out the nerves.

"That will have to wait for more patients to be replaced with new prosthetic limbs. In addition, some heavy-duty sports can't be done. But, aren't you a runner?"

Zhao Guoping laughed and said: "You can run as a disabled person without hands. However, I used to participate in the sports meeting because I had nothing to do. After I have hands, I must go to work."

Sun Tai'an nodded: "However, exercise should be exercised."

"That's right, I have to run a few kilometers every day, otherwise I'm not used to it." Zhao Guoping nodded, and suddenly asked: "By the way, doctor, how soon can I be discharged from the hospital after the operation?"

"It needs to be observed for about half a month, but during this half month you can move freely around the hospital, and you can use your novice to do some stretching exercises and the like."

"In addition, because everyone's bones are different, they can do different exercises. However, we have checked your bones and found that they are harder than ordinary people, so you can do some heavy-duty exercises."

"Okay, thank you doctor."

Sun Tai'an nodded, said no more, and continued with his work.

Find out the main nerve, and then connect the artificial nerve with it, followed by the nerve electrical signal recognition chip, and the tactile sensing circuit.

The two circuits are connected in parallel and share one artificial nerve. This is also an optimized solution, and there is no need to use two artificial nerves.

Then there is the bone arm connector, insert the chip, align with the four nuts on the bone, and then press lightly, and the two parts are easily buckled together, which is very firm.

Next, is the last part.

Exoskeleton prosthetics.

The assistant next to him handed over a metal arm.

With a metallic luster on the surface, anyone can't help but think of Iron Man, and then sigh handsome, and want to install it himself.

But the only pity is that this requires an operation on yourself, so forget it.

Everyone concentrated their attention and watched Sun Taian's next actions. Next, they will witness with their own eyes——

Miracle!
