I can extract side effects - Chapter 643

c639 surgical robot

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

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

In a spacious room, seven or eight people are surrounding a screen, exclaiming in amazement.

Among them, Wang Dali sat in front of the console, his back straightened, but his head was deeply buried in a compartment, and his hands were carefully operating the handles.

“Boss, 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 it’s going to take advantage of our brothers.”

“Haha, these grapes are not easy to peel. Brother Wang must have practiced a lot at home.”

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

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

At the top of the metal claws are two small pincers 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 is the skin thin, but it is also very difficult to tear off. With a slight shake of the hand, a large piece of the grape flesh will be peeled off.

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

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

The whole process seemed easy, and the peeled skins were very thin, and the pulp of the grapes was intact without any damage.

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

Afterwards, the metal claw grabbed a bamboo stick with grapes on it again, placed it in front of it, and repeated the peeling operation again.

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

He basically gets a grape, and he can peel off a whole grape fruit by three times, five times and two divisions. The whole process does not exceed 10 seconds.

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

After the crowd of onlookers finished marveling, they all watched tacitly, admiring Wang Dali’s smooth operation.

Finally, after the last grape was placed on the plate.

The camera pans to another plate, which is empty.

Only then did Wang Dali put down the handle, stretched lazily, and said with a smile.

“How about it? You’ve seen enough, why are you still staring, bring the grapes and eat them together.”

Everyone froze 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 in his mouth and bit it, the sweet juice splashed in his mouth, and he immediately showed a satisfied smile.

Others also stretched out their hands one after another, and the grapes on the plate were wiped out in an instant.

There are a lot of bamboo sticks, but there is only one grape on each stick, so each person gets two or three grapes.

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 have watched 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 in a hurry.

“The field of view is very clear, and the coordination of the three manipulators is also very good.”

“The precision of the operation is very high. The grape skin was precisely torn off without piercing the pulp.”

“It can be seen that the free movement of the mechanical arm is very large, and there are several operations in it, which are simply not possible for human hands.”

“The stabilizer works well, and the stability is much better than that of human hands. If you want to replace it with Brother Wang’s own hands, it’s likely that your hands will shake a long time ago.”

“It’s still too simple. Other functions, such as surgical field of view and 3D stereoscopic imaging, have not been detected. It’s better to try more complicated operations.”

“By the way, Brother Wang, what is your experience when you use it yourself?”

Hearing this question, Wang Dali pondered for 3 seconds before speaking slowly.

“It feels amazing, as if I have a few more hands, and it seems that my hands have been extended, and even become extremely soft, able to bend 360 degrees without dead ends, and perform many movements that were not possible before.”

“It’s as if, as if my hands have become two extremely flexible tentacles.”

“Actually, it’s not that I haven’t thought about what it will be like to work after my hand becomes a robot.”

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

“That is, the mechanical hand still lacks tactile reflex, so I can’t feel the touch of grape skin and pulp, which is different from the real hand.”

“However, the flexibility and precision are definitely much better than real hands, and the stability is also better.”

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

Speaking of this, he suddenly looked to the opposite side: “Xiao Lu, don’t you study clinical medicine? You know how to perform surgery, so let’s see if it works.”

Xiao Lu was a young man in his mid-twenties with a crew cut, and came over cheerfully upon hearing this.

“Boss, my basic surgical suture skills are pretty good.” He thumped his chest and said, “It’s not a problem to suture a grape skin.”

Wang Dali nodded and said with great admiration: “Sure enough, professional ones are different. I will also peel the skin, and it depends on you to sew it up.”

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

Sitting in front of the console, Xiao Lu first grasped the handle, moved the mechanical arm, and tested the feel.

After all, he didn’t have much chance to use a surgical robot in school before, and this was the first time he tried it on a machine.

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

But suturing, which belongs to the basic exercises, is as proficient as a middle school student writing with a pen for a surgeon. Even if you change from a pen to a brush, it will only affect your proficiency, not make it impossible to use.

So he tried it a little bit, became familiar with the operation of the handle, and felt that there was no problem, so he officially started the performance.

At the beginning, of course, the grape skins were peeled, and then the peeled grape skins were stitched together.

Looking at the camera, one mechanical hand held the bamboo stick, and the other two mechanical hands precisely tore off a long strip of grape skin.

Then, the robot gently covered the grape skins.

The suture thread has been prepared a long time ago. This 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 mechanical 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 together.

The first stitch is over.

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

I saw thin silver wires entangled between the two mechanical hands, under Xiao Lu Yidun’s dazzling operation.

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

Seeing this scene, Wang Dali and others exclaimed on the spot, and the applause was endless.

“Nice job!”

“Okay, I can’t see that you still have such a skill.”

“Awesome—”

“Mom, I didn’t see anything, why did I tie the knot.”

“Is this how surgeons tie knots?”

“I can thread a needle, but I really can’t tie a knot.”

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

Under his operation, the robotic hand is even more flexible and changeable than a real person’s hand, completing a series of sewing actions very easily and accurately.

Soon, the robotic hand threaded the last stitch and tied the last knot on the grape tail.

At this point, the torn grape skins are completely sewn.

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

Very flat and smooth, just like nature, without any warping or wrinkling.

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

Xiao Lu breathed a sigh of relief when he finished cutting the thread, and fine sweat oozes from 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 skins.

Clap clap!

There was a burst of warm applause at the scene.

Wang Dali applauded extraordinarily hard, his palms turned red, and he was reluctant to stop.

“Xiao Lu, you are no worse than a surgeon.”

Xiao Lu stood up, blushing slightly, and said modestly: “Actually, I have been a trainee for three years, and I have rotated in surgery, and I have also done hooking, but now my skills are all neglected.”

Wang Dali was very surprised: “I thought you entered the company directly after graduation. Why didn’t you become a doctor and went to a pharmaceutical company instead?”

Xiao Lu scratched his head, a little embarrassed: “The main thing is that Peisheng is too tired. He works overtime every day until the early morning, and his monthly income is only a thousand yuan. He can’t support himself at all, and his parents have to pay for living expenses. I really can’t stand it. Just run away to the business.”

“At least Sanqing pays more money, and what he does is to save lives and heal the wounded. It’s not worse than doctors.”

Wang Dali suddenly showed sympathy in his eyes: “It was too hard. It was really difficult to survive the first few years of studying medicine. No wonder people say that those from poor families should not study medicine.”

Xiao Lu smiled wryly and said, “That’s right, you really can’t study medicine if you don’t have any background at home. Gui Peisheng is not a regular employee, has no performance, only hard work, and is not regarded as a human being at all.”

“I was in general surgery at the time. You can’t imagine that there are 10 doctors in a department, 3 chief physicians, 5 deputy directors, and a new doctor who is the chief resident. He is not on duty and mainly does scientific research.”

“The entire department doesn’t even have an attending doctor. There are only a dozen or so regular trainees working as cattle and horses. They can do all kinds of dirty work. It’s cheap labor.”

There was a hint of the feeling of the rest of his life in his eyes, and he took a deep breath.

“About us, Gui Peisheng, a doggerel is dedicated to everyone.”

“Shanglian: There are endless medical records, endless patients, endless emergency visits, and endless phone calls.”

“The second line: Endless operations, endless wounds, endless chores, endless night shifts.”

“Horizontal batch: Niu Magui Peisheng.”

“Hahaha~, it’s a good thing I passed away early, I am completely relieved now.” Xiao Lu laughed at himself after finishing speaking.

“This…is really pitiful. Haha.” Wang Dali also laughed a few times in agreement, and then asked.

“I feel that 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, then gritted his teeth.

“Of course, the length of the grapes is less than 2.5 centimeters, and the thickness of the grape skins is less than 1 millimeter. Although it is very fragile, it is really not difficult.”

“It is more difficult to sew raw eggs. The inner membrane of raw egg shells is only 0.07 mm thick, which is much thicker than grape skins. It is thin and brittle. The difficulty of sewing is not ordinary.”

“If the manipulator can complete the operation of suturing raw egg membranes, the fineness and difficulty must be full.”

“Okay!” Wang Dali applauded again: “Then let’s try this and see how you perform.”

Xiao Lu pursed his lips tightly, showing a heroic expression, like a warrior about to go to the battlefield, he nodded resolutely.

He wasn’t sure about suturing raw egg membranes. Although he could do it in the hospital before, he hadn’t had surgery for almost a year, so he wasn’t sure if he could do it.

But it’s okay, it’s not a road show in public, and no mistakes are allowed.

Doing it in the laboratory is just an exercise, and the error tolerance rate is very high.

Everyone present is my own person, even if I mess up the first time, I can try a few more times, and I will always become proficient and complete this difficult operation.

Thinking of this, he didn’t feel so anxious anymore, he felt relieved, it was just a normal practice.

Everyone is a straight man in science and engineering, with strong execution ability. After a quarter of an hour, someone bought a few raw eggs from the cafeteria.

Xiao Lu carefully placed the raw eggs in a small bowl, covered them with thick paper towels, fixed them, and placed them on the operating table.

This time, a thinner silk suture is used, 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 stitching was about to start, everyone crowded around the screen.

Even some colleagues who are working outside have heard the news and rushed to watch this rare event.

Xiao Lu raised his head and looked at the huge crowd, suddenly feeling a lot of pressure.

But when things came to an end, there was no choice but to bite the bullet.

Luckily, his hands tremble with nervousness, but the robot doesn’t.

Under his control, the mechanical hand carefully controlled the strength, and peeled off the eggshell on the top of the egg in small pieces.

Under the high-definition line of sight, a white film appears in the center of the screen, slightly sunken.

The sharp tip of the manipulator pierces the film as silently as a knife cuts through butter.

The film was torn apart in an instant, showing a gap as wide as the Yarlung Zangbo Grand Canyon.

You can vaguely see the wavy egg white below, rippling gently.

Oops, the egg whites are about to flow out.

Everyone thought so in their hearts, and instantly opened their eyes wide, staring at the screen, and let out a heavy gasp.

However, the expected scene of egg white bubbling out did not happen.

On the screen, the manipulator dexterously shuttles between the silk 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 up stitch by stitch.

It’s so cool!

It was able to fly needles on the raw egg membrane of 0.07mm, and the suture was completed without any effort.

Such thoughts flashed through everyone’s minds and quickly took root.

Everyone’s mouths opened unconsciously, big enough to fit an egg in, and shocked expressions appeared on their faces, astonished by the delicate operation under the camera.

The audience was so silent that one could hear a needle drop on the ground.

In this way, until Xiao Lu cut off the thread, the egg membrane became intact again.

Only on the white film, there is a row of black fine stitches that seem to be absent.

There was a burst of thunderous applause at the scene.
