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 sat in front of the control console, his back straight, his head deeply buried in a compartment, and his hands carefully operated 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, so she wants to 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. The skin is not only thin, but also very difficult to tear. If you shake your hand 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 looks easy, and the skins peeled off are very thin, and the pulp of the grapes is intact without any damage.
After peeling 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.
Basically, he gets a grape and can peel out a complete grape pellet three times, five times and two times. 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 turns to another plate, which is 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 point.
"You guys have been watching it for so long. What do you think of the operation of this robot?"
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, and the grape skin 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 inside 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 have been 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?"
Wang Dali heard this question and pondered for 3 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 thought 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 the 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. Come and try to see if it works."
Xiao Lu is a young man in his mid-twenties with a crew cut. When he heard this, he came over happily.
"Boss, my basic suturing skills in surgery are pretty good." He pounded 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. 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 a surgeon as writing with a pen for a middle school student. Even if you 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 has been prepared for a long time. It is a silver-white metal thread that is as thin as a hair and has a certain degree of toughness. It is not as soft as ordinary cotton thread.
The robotic hand danced gently, holding the grape skin with one hand, and threading 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 thin silver wires 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, with endless cheers.
"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 robotic 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 one.
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!
There was a burst of 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."
Xiao Lu stood up, with a slight blush on his face, and said modestly: "Actually, I have been a trainee for three years, rotated in surgery, and also used to pull hooks, but now my skills have been abandoned."
Wang Dali was very surprised: "I thought you entered the company directly after graduation. Why didn't you become a doctor and instead went to a pharmaceutical company?"
Xiao Lu scratched his head, feeling a little embarrassed: "Mainly, I am too tired as a trainee. I work overtime until early in the morning every day, and my monthly income is only a thousand yuan. I can't support myself at all, and my parents have to pay for living expenses. I really can't stand it. He just ran away and came to the enterprise."
"At least Sanqing pays more, and what he does is save lives and heal the wounded. He's not that bad compared to doctors."
Wang Dali suddenly showed sympathy in his eyes: "It's too hard. It's really difficult to survive the first few years of studying medicine. No wonder people say that people with poor family conditions should not study medicine."
Xiao Lu smiled bitterly and said, "That's because I really can't study medicine because I don't have any foundation at home. Trainees are not regular employees and have no performance. They only work hard and are not treated as human beings at all."
"I was in general surgery at the time. You can't even imagine that there were 10 doctors in one department, 3 chief physicians, 5 deputy directors, and a new doctor who was the chief resident. He didn't have to be on duty and was mainly engaged in scientific research."
"The entire department doesn't even have an attending physician. There are only a dozen regular trainees working as cows and horses. They do all the dirty work. They are cheap labor."
There was a hint of the feeling of surviving a disaster in his eyes, and he took a deep breath.
"About our graduate students, a limerick is dedicated to everyone."
"First couplet: Endless medical records, endless admissions of patients, endless emergency department visits, and endless phone calls."
"Second line: endless surgeries, endless wounds, endless chores, endless night shifts."
"Hengbiao: Niu Ma Guipei Sheng."
"Hahaha~, luckily it's all over now, I'm completely relieved now." After Xiao Lu finished speaking, he laughed self-deprecatingly.
"This... is indeed a bit pitiful. Haha." Wang Dali laughed a few times in agreement and then asked.
"I feel like sewing grape skins is a bit too easy for you. Is there any more difficult operation?"
"It's more difficult." Xiao Lu pondered for a moment and gritted his teeth.
"Of course, the length of the grapes is less than 2.5 centimeters, and the thickness of the grape skin is less than 1 millimeter. Although it is very fragile, it is not difficult."
"The more difficult thing is to sew raw eggs. The inner membrane of raw egg shells is only 0.07 mm thick, which is much thicker than grape skin. It is thin and brittle, so it is not ordinary to sew."
"If a robot can complete the operation of sewing raw egg membranes, the precision and difficulty will definitely be high."
"Okay!" Wang Dali clapped again: "Then let's try this and see how you perform."
Xiao Lu pursed her lips tightly, showing a heroic expression, like a warrior about to go to the battlefield, and nodded resolutely.
He wasn't sure about suturing raw egg membranes. Although he could do it in the hospital before, he hadn't had any surgery in almost a year, so he wasn't sure whether he could do it.
But it's okay, it's not a road show in public, so there is no room for any mistakes.
Doing it in the laboratory is just practice, and the error tolerance is very high.
You are all on your own here. Even if you mess up the first time, you can still try a few more times and you will gradually become proficient and complete this difficult operation.
Thinking of this, he was no longer so anxious. He felt relieved and regarded it as a normal training session.
Everyone was straight men in science and engineering, and they were very good at execution. After a quarter of an hour, someone bought a few raw eggs from the canteen.
Xiao Lu carefully placed the raw eggs in a small bowl, placed thick paper towels around them, fixed them, and placed them on the operating table.
This time, I used a thinner silk suture, which is soft and knotted firmly. It is generally used to suture skin tissue and is the most common suture for cosmetic surgery.
Seeing that the suturing was about to begin, everyone gathered in front of the screen with a roar.
Even some colleagues who were working outside heard the news and came over to watch this rare event.
Xiao Lu raised his head and looked at the huge crowd, suddenly feeling extremely stressed.
But when things came to a head, I had no choice but to bite the bullet.
Luckily, his hands would shake with nervousness, but the robot wouldn't.
Under his control, the robot hand carefully controlled the force and peeled off the eggshell on the top of the egg piece by piece.
Under high-definition viewing, the white film appears in the center of the screen, slightly sunken.
The sharp tip of the robot hand penetrates the film silently, like a sharp knife cutting through butter.
The film tore open instantly, revealing a gap as wide as the Brahmaputra Grand Canyon.
The wavy egg white below can be vaguely seen, rippling gently.
Oops, the egg white is about to flow out.
Everyone was thinking this, and their eyes widened in an instant, staring at the screen, and breathing heavily.
However, the expected scene of egg white gurgling out did not happen.
On the screen, the robot hand flexibly shuttles between the threads like a butterfly flapping its wings.
Almost in the blink of an eye, the torn hole in the egg membrane was quickly closed and stitched together stitch by stitch.
How cool!
It is actually possible to fly stitches on a 0.07mm raw egg membrane and complete the stitching effortlessly.
Such thoughts flashed through everyone's minds and quickly took root.
Everyone's mouth opened unconsciously, big enough to fit an egg in, and expressions of shock appeared on their faces, shocked by the exquisite operation under the camera.
The whole place was completely silent, so quiet that you could hear a pin drop.
That's it, until Xiao Lu cut off the thread and the egg membrane became intact again.
Only a row of fine black stitches were left on the white film.
A burst of thunderous applause erupted from the scene.
