Just when Xue and Chen were working hard on the nerve regeneration scaffold.

On another floor of the same building, Wang Dali’s surgical robot project also made its first prototype.

In a spacious room, seven or eight people were surrounding a screen, exclaiming in admiration.

Among them, Wang Dali was sitting in front of the control console, his back straight, his head deeply buried in a compartment, and his hands were carefully operating on the handles.

"Tou, you are so awesome."

"This technique of peeling grapes is really amazing!"

"Tsk, tsk, it's a pity that my sister-in-law is not here, she will take advantage of us brothers."

"Haha, these grapes are not easy to peel. Brother Wang must have been practicing at home a lot."

At this time, a purple-red grape appeared on the screen. It was inserted on a bamboo stick, and a mechanical claw clamped it firmly so that it could not rotate.

In addition, there are two slender metal mechanical claws, which are peeling grapes under the control of Wang Dali.

The top of the metal claw is two small pliers with precise structure, which can be bent freely in different directions and operated at various angles.

People who often eat grapes know how difficult it is to peel grapes. Not only are their skins thin, but they are also very difficult to tear. If you shake your hands even slightly, a large piece of the grape flesh inside will be ripped off.

But such a difficult task is extremely easy under the metal claws.

The three claws work very well together. One claw is used to fix the grapes on the bamboo stick, one is used to gently pierce the grape skin, and the other claw is used to clamp the grape skin and tear it off quickly.

The whole process seems easy, and the skins peeled off are very thin, and the pulp of the grapes is intact without any damage.

After peeling the skin of a grape, the crystal clear light green fruit was carefully placed on the plate on the left by metal claws.

Then, the metal claws once again grabbed a bamboo stick with grapes on it, placed it in front of them, and repeated the peeling operation.

Peeling and peeling, Wang Dali's movements became more and more skillful and faster.

He basically gets a grape and can peel out a complete grape berry by dividing it by three and five. The whole process does not take more than 10 seconds.

As time goes by, layers of bamboo sticks are constantly stacked on the plates on the operating table.

After the crowd of onlookers finished marveling, they all started to watch in tacit understanding, admiring Wang Dali's smooth operations.

Finally, the last grape was put on the plate.

The camera turned to another plate, which was empty.

Wang Dali then put down the controller, stretched lazily, and said with a smile.

"How's it going? You've seen enough. Why are you still standing there? Bring the grapes and eat them together."

Everyone was stunned for a moment, and then burst into cheers.

Immediately, an engineer quickly ran to the operating table one meter away and brought back a plate of peeled grapes.

Wang Dali grabbed a bamboo stick, put it into his mouth and took a bite. The sweet juice splashed in his mouth, and he suddenly showed a satisfied smile.

Others also stretched out their hands, and the grapes on the plate were swept away in the blink of an eye.

There seemed to be a lot of bamboo sticks, but there was only one grape on each stick, so each person only got two or three.

After eating, everyone licked their lips, feeling a little unfinished.

But this was obviously just an appetizer, and everyone quickly got to the main topic.

"You guys have been watching it for so long, what do you think of the operation of this robot hand?"

Wang Dali put away his smile and asked seriously.

Everyone spoke at once.

"The field of view is very clear, and the coordination of the three robot arms is also very good."

"The surgical movements were very precise. The skin of the grape was accurately torn off without breaking the flesh."

"It can be seen that the robot arm has a great degree of freedom of movement, and there are several operations that are simply not possible by human hands."

"The stabilizer works well. The stability is much better than that of human hands. If it were replaced by Brother Wang's own hands, most likely his hands would be shaking."

"It's still too simple. No other functions were detected, such as surgical field of view and 3D stereoscopic imaging. It's best to try more complex operations."

"By the way, Brother Wang, how do you feel about using it yourself?"

When Wang Dali heard this question, he thought for three seconds before speaking slowly.

"It feels amazing, as if I have a few more hands, and it seems like my hands have lengthened, and even become extremely soft. I can bend them 360 degrees without any dead ends, and complete many actions that I couldn't do before."

"It's as if my hands have turned into two extremely flexible tentacles."

"Actually, I haven't thought about what it would be like to work after my hands become robot hands."

"But I never expected that this day would come so quickly and that I can experience it now."

"That is, the robotic hand still lacks tactile reflexes, so I can't feel the touch of the grape skin and pulp, which is different from a real hand."

"However, the flexibility and accuracy are definitely much better than those of a real hand, and the stability is also better."

"The operation is very easy and convenient. I have never had any surgery, but such a simple peeling operation does not feel difficult at all."

After saying this, he suddenly looked to the other side: "Xiao Lu, aren't you a clinical major? You know how to do surgery. Let's try to see if it works."

Xiao Lu is a young man in his mid-twenties with a crew cut. He came over happily when he heard this.

"Boss, my basic suturing skills in surgery are pretty good." He banged his chest and said, "There's nothing wrong with suturing a grape skin."

Wang Dali nodded and said with great appreciation: "Sure enough, the professional ones are different. I can also peel the skin, and it's up to you to sew it up."

At that moment, someone brought some bunches of grapes and handed them to Xiao Lu.

Xiao Lu sat in front of the console, first grabbed the handle, moved the robotic arm, and tried the feel.

After all, he had not had much opportunity to use surgical robots in school before, and this was his first time trying it on a machine.

It stands to reason that doctors using surgical robots need to undergo strict systematic training.

But suturing, a basic exercise among basic exercises, is as proficient for surgeons as middle school students writing with a pen. Even if they switch from a pen to a brush, it will only affect the proficiency, not the inability to use it.

So he tried it out for a while, became familiar with the operation of the handle, and felt that it was not a big problem, so he officially started performing.

Of course the first step is to peel the grape skins, and then sew the peeled grape skins back on.

Looking at the camera, one robot hand holds the bamboo stick while the other two robot hands accurately tear off a long strip of grape skin.

Then, the robot hand gently covered the grape skins.

The suture thread has been prepared for a long time. It is a silver-white metal thread, as thin as a hair, with a certain degree of toughness, not as soft as ordinary cotton thread.

The robot hand danced gently, holding the grape skin with one hand, and passing the silver thread through the grape skin with the other hand to join the two sides.

The first stitch is over.

Next, it’s time to show the real technology.

I saw a thin silver wire entangled between the two robot hands, under Xiao Lu's dazzling operation.

The silver thread perfectly tied the first knot on the grape skin.

This scene made Wang Dali and others exclaim on the spot, and the cheers continued.

"Well done!"

"Okay, I can't tell you have such a skill."

"Awesome——"

"Oh my god, I didn't see anything, why did it get knotted?"

“Is this what a surgeon does when he ties knots?”

"I can thread a needle, but I really can't tie knots."

Xiao Lu concentrated his attention and continued to sew stitch after stitch.

Under his operation, the robot hand was more flexible and versatile than a real hand, completing a series of sewing movements very easily and accurately.

Soon, the robot hand threaded the last stitch and tied the last knot at the end of the grape.

At this point, the torn off grape skin has been completely sewn.

Except for an extra row of fine stitches on both sides, there is no difference from the original.

It is very smooth and smooth, as if made from nature, without any warping or wrinkles.

It is conceivable that if grapes have the ability to heal themselves like animals, they will definitely turn into a flawless original grape in a few days.

After Xiao Lu finished cutting the thread, he breathed a sigh of relief, and a thin layer of sweat broke out on his forehead.

He was quite satisfied with his performance. He finally fulfilled his mission, did not embarrass the medical students, and successfully completed the suturing of the grape skin.

Bang bang bang!

The scene immediately burst into warm applause.

Wang Dali clapped extra hard, his palms turned red, and he was reluctant to stop.

"Xiao Lu, your skills are no worse than those of a surgeon."
