Her name is Jiang Shuya, and she works at Pengcheng Mead Surgical Hospital.

She invited Ye Qing to take her bionic hand to the hospital where she worked, because there was a professional prosthetic fitting center.

It's a good idea.

But!

Ye Qing had thought about it before.

Ye Qing is also half a factory family, and in the early years, when the implementation of safety production regulations was not in place, work-related injuries were commonplace in the park.

A broken finger, that's called the lucky one.

Like a female worker's hair being twisted by a machine, the whole person is rolled into the machine, which belongs to the old yellow calendar.

Someone was wringing into the machine tool with gloves and hands because they were wearing labor gloves. Someone was operating the wheel cutting machine, and a worker walked by, and as a result, the cutting wheel cracked, piercing the legs of the person passing by.

These are basic and can be avoided by simply reading the safety manual.

There are also those that cannot be guarded against, and which novices simply can't imagine.

For example, Ye Qing heard that in a certain factory, there were workers operating large punching presses, and the workers inadvertently put their hands on the steel plate to be stamped.

A large steel plate, the place that needs to be stamped may be only the size of a basin, and there is still a long distance from the worker's hand. Normal people will not be too vigilant under this kind of thinking, and they will not feel inappropriate to put their hands on the steel plate unintentionally.

As a result, the hammer fell, and all four fingers of the worker were washed off in unison.

Pretty puzzling?

But the flesh and blood body, in the face of the instant vibration caused by the hammer hitting the steel plate, is not much tougher than tofu.

The vast majority of work-related injuries occur in factories, and hand injuries are the most common. Therefore, Ye Qing has long thought about the application of industrial technology in prosthetics.

But Ye Qing has never put it into practice, because even if the bionic joints are perfect, they can't avoid a problem.

"Let's not talk about whether Biotobock is brilliant or not, I have a question here. ”

"How do patients operate bionic joints?"

"For example, if I type to you now, my brain stimulates the nerves, which then release bioelectric signals to control the muscles of my hands to make corresponding movements. ”

"When it comes to bionic joints, there is a disconnect between the nerves and the machinery. No matter how the brain stimulates the nerves, the bionic joints will not respond. ”

"Then the question is, even if the bionic joint is done well, it can't move, what's the use?"

"You can't give the user a remote control and let him control the bionic hand. There is also no remote control, which can compile the actions that the user wants. ”

Ye Qing told Jiang Shuya about this problem, but it stands to reason that Jiang Shuya would not be unaware of this problem.

"Your question hits the nail on the head. Jiang Shuya took more than ten seconds before replying to Ye Qing.

"I can tell you about the Ottobock solution. ”

They attached two electrode sensors to the stump of the user's arm, and the electrode iron piece sensed the biocurrent generated when the stump, flexor and extensor muscles were tight. With this biocurrent, their manipulator can help the user complete the grasping work. ”

Ye Qing nodded in agreement, and then replied, "I understand." ”

"But, if I'm guessing correctly, they can only do simple scraping jobs too. ”

"You mentioned earlier that they have 3D force sensors in their products. In other words, their products can simply determine the weight of the grasping object, and then control the strength of the force output by the micro motor. ”

"With this in mind, it can do a simple grab. There is no dilemma of grabbing a glass and crushing it. ”

"But what if the user wants to use it to write, type on the keyboard, smoke a cigarette, or finish buttoning and zipping up?"

"It can't do it. ”

"This kind of myoelectric hand must be a connecting rod structure, and it will have obvious mechanical frustration and mechanical noise in use. This also means that it consumes a lot of energy and needs to be regularly oiled. ”

"Our products, though, can solve mechanical defects. But in terms of software, it will only lag behind Ottobock. ”

"What Ottobock products can't do, we can't do. ”

"You can cooperate!" Jiang Shuya's tone was excited.

"Ottobock has many years of experience in software, and they are always working to improve the recognition of electrode sensors, so if you two companies work together, ......"

"The business side is not as simple as you think. Ye Qing didn't say very bluntly that Ottobock would not come up with an effective plan even if he improved for another ten years.

In addition, Ottobock's software control was far from ideal. ”

"With their technology, using our products in prosthetics is a pain for the patient, and it is also for us. ”

Jiang Shuya asked cautiously, "Then what is your purpose in developing this bionic hand?"

"A VR spin-off. Ye Qing replied.

"Ah~ You have such advanced technology, but you use it to make game products. Jiang Shuya had a very hard time understanding this line of thinking, "Don't you think it's greater than games to benefit those with physical defects?"

“……”

Ye Qing was speechless.

"Even if there is difficulty in software control, you can slowly tackle the problem, right?" Jiang Shuya earnestly taught, "Even if you don't cooperate with Ottobock, you can cooperate with our hospital." We have a professional prosthetic fitting center here, as well as a large amount of accumulated neurological and bioelectric data. ”

"Some patients with nerve injuries use bioelectrical stimulation when they are doing rehabilitation exercises with us. ”

"All the data is available for free. ”

“……”

Ye Qing was even more speechless.

Jiang Shuya is simply a model of an angel in white.

However, Jiang Shuya only knows one and doesn't know the other.

Even Ye Qing built on the basis of the black technology of the monster factory, and he couldn't think of a solution to solve the problem of matching the bionic hand with the nerve. Even if you push the product to users with physical disabilities, what else can you do but let them waste money and have fun?

"Well, I'll propose this to the company. ”

"But I can't guarantee that it will be successful. ”

"Then please. Jiang Shuya was full of hope.

When the call ended, it was twelve o'clock in the evening.

Ye Qing knew that doctors were very busy, especially surgeons like Jiang Shuya.

Ye Qing put his phone aside and meditated quietly, he was thinking of a solution.

Then I opened my eyes again, and it was dawn.

With the idea of brainstorming, Ye Qing called the electrocrystal to the office and asked if it had a solution.

"Boss, isn't asking me about this deaf. Dianjing spread his hands very sloppily, "You have a solution, I'm in charge of software compilation, no problem." But if you ask me about human nerves, you look at me like this, I seem to understand this. ”

Ye Qing looked at the electrocrystal.

What appeared in Ye Qing's vision was a creature with long ears and a translucent body, with lightning flashing in it from time to time.

That's really the wrong question......
