Her name was Jiang Shuya, and she worked at the Meade Surgical Hospital in Pengcheng City.
She invited Ye Qing to take the bionic hand to the hospital where she worked because there was a professional prosthetic installation center there.
This was a very good idea.
But!
Ye Qing had thought about it before.
Ye Qing could be considered half a factory family. In the early years, when the safety production regulations were not in place, things like work injuries were common in the park.
A broken finger was called a lucky dog.
It was like a female worker's hair being twisted by a machine, and her whole body being rolled into the machine, which belonged to the old days.
Because some people were wearing work gloves, they ended up being twisted into the lathe together with the gloves. Someone was operating a wheel cutter, and a worker walked by. As a result, the cutting wheel broke and pierced through the legs of people passing by.
These were basic and could be avoided as long as one read the safety manual carefully.
There were also things that were impossible to guard against and that novices could not imagine at all.
For example, Ye Qing had heard of a factory where a worker was operating a large punch press. The worker inadvertently put his hand on the steel plate to be punched.
A large piece of steel plate that needed to be punched might only be the size of a washbasin. It was still a long way from the worker's hand. Normal people would not be too vigilant under this kind of thinking. They would not feel that it was inappropriate to put their hand on the steel plate inadvertently.
As a result, the hammer fell and the worker's four fingers were washed off.
Was it very puzzling?
But the flesh and blood body was not much tougher than tofu in front of the instant shock caused by the hammer hitting the steel plate.
Most of the injuries caused by work injuries occurred in factories, and hand injuries were the most common kind. Therefore, Ye Qing had long thought about the application of industrial technology in prosthetics.
However, Ye Qing had never put it into practice, because no matter how perfect the bionic joint was, it could not avoid a problem.
"Let's not talk about whether it's brilliant or not. I have a problem here."
"How does the patient operate the bionic joint?"
"For example, I'm typing to you now. It's my brain that stimulates the nerves. The nerves then release bioelectric signals to control the muscles of the hand to make the corresponding movements."
"At the bionic joint, the nerves and machinery have a fault. No matter how the brain stimulates the nerves, the bionic joint will not respond. "
"Then here's the problem. No matter how good the bionic joint is, what's the use if it can't move?"
"We can't give the user a remote control and let him remotely control the bionic hand, right? There is also no remote control that can compile the user's desired actions. "
Ye Qing told this to Jiang Shuya, but it was reasonable to say that Jiang Shuya should know about this.
"Your question hit the nail on the head," Jiang Shuya replied to Ye Qing after more than ten seconds.
"I can tell you Otto Bock's solution."
"They use two electrode sensors to attach to the stump of the user's arm. The electrode iron can sense the bioelectric current generated when the flexor and extensor muscles are tense. With this kind of bioelectric current, their mechanical hands can help the user complete the grasping work. "
Ye Qing nodded in agreement and replied, "I understand."
"However, if my guess is correct, they can only complete a simple task of grabbing."
"You mentioned before that their product has a three-dimensional force sensor. In other words, their product can simply determine the weight of the object it grabs and then control the strength of the micro-motor output. "
"According to this train of thought, it can complete a simple grab. There won't be a dilemma of grabbing a glass and crushing it. "
"But what if the user wants to use it to write, type on the keyboard, smoke, or complete the action of buttoning and zipping?"
"It can't do that."
"This kind of myoelectric hand must be a linkage structure. It will have a clear mechanical pause and mechanical noise in use. This also means that it consumes a lot of energy and needs regular oil maintenance. "
"Although our product can solve mechanical defects. But in terms of software, it will only lag behind Otto Bock. "
"What Otto Bock's product can't do, we can't do either."
"You can work together!" Jiang Shuya's tone was excited.
"Otto Bock has many years of experience in software. They have also been working hard to improve the identification of the electrode sensor. If the two companies work together …"
"The business side is not as simple as you think." Ye Qing did not say it bluntly. Even if Otto Bock improved for another ten years, they would not be able to come up with an effective plan.
"In addition, Otto Bock's software control is far from the ideal requirements."
"With their technology, using our product on the prosthetic limb is a kind of pain for the patient. It is the same for us."
Jiang Shuya asked carefully, "Then what is your purpose in developing this bionic hand?"
"A derivative product of VR," Ye Qing replied.
"Ah, you have such advanced technology, but you use it to make game products." Jiang Shuya found it very difficult to understand this kind of thinking. "Don't you think that compared to games, isn't it greater to use it to benefit those with physical defects?"
"…"
Ye Qing was speechless.
"Even if there are difficulties in software control, you can slowly tackle them, right?" Jiang Shuya taught him earnestly, "Even if you don't cooperate with Otto Bock, you can cooperate with our hospital. We have a professional prosthetic limb installation center here, and we also have a lot of accumulated data on nerves and bioelectricity. "
"Some patients with nerve damage will use bioelectric stimulation programs when they do rehabilitation training here."
"We can provide all the data for free."
"…"
Ye Qing was even more speechless.
Jiang Shuya was simply the model of an angel in white.
However, Jiang Shuya only knew one thing and did not know the other.
Even Ye Qing, based on the black technology of the monster factory, could not think of a solution to the match between the bionic hand and the nerves. Even if the product was pushed to users with physical defects, what else could it do other than waste their money and be happy for nothing?
"How about this, I will propose this plan to the company."
"But I can't guarantee success."
"Then I'll leave it to you." Jiang Shuya was full of hope.
It was already midnight when the call ended.
Ye Qing knew that doctors were very busy, especially chief surgeons like Jiang Shuya.
Ye Qing put his phone aside and meditated quietly. He was thinking of a solution.
Then, when he opened his eyes again, it was dawn.
With the idea of brainstorming, Ye Qing called Dian Jing to the office and asked if it had a solution.
"Boss, asking me about this is the same as asking a deaf person." Dian Jing spread its hands like a hoodlum. "If you have a solution, I'm responsible for the software compilation. But if you ask me about human nerves, look at me. Do I look like I understand this? "
Ye Qing looked at Dian Jing.
What appeared in Ye Qing's field of vision was a creature with long ears, a translucent body, and lightning flashing in it from time to time.
