Vol 2 Chapter 1159: How to get a paralyzed patient to stand up

In fact, Wu Hao had expected that many people would not believe his words before this. Therefore, he has already made relevant countermeasures.

Suppressing his hand a little to stop the discussion in the audience, Wu Hao then went on to say: "I know that you may have doubts about this, thinking that I am talking big or exaggerating to mislead everyone.

But please rest assured, we dare to announce this news at such a formal conference, then it proves that we have enough confidence in our products. "

Seeing the guests in the audience were quiet, Wu Hao secretly breathed a sigh of relief, and then continued: "There are many patients who are paralyzed, and there are many causes of paralysis, so I picked out that everyone is most interested in it. I will give you an example of the older patients with lower limb paralysis.

There are many reasons for lower extremity paralysis. There are mainly two common reasons. One is lower extremity paralysis caused by brain diseases, such as intracerebral hemorrhage, compression of motor nerves, and lower extremity paralysis.

The other is paralysis of the lower limbs caused by spine disease or trauma.

For these two types, we also have related treatment plans, but because of different causes, treatment plans will be very different.

From easy to difficult, let's first talk about the relatively simple treatment, which is paralysis of the lower limbs caused by spinal diseases.

Here I want to say one thing in advance, that is, our medical intelligent mechanical exoskeleton product cannot directly cure this disease, but can only play a function and role in correcting and restoring sports ability.

At this point, it is the same as the myopia, hyperopia or astigmatism glasses we wear. When you take off the glasses, your myopia is still myopia, and the astigmatism is still astigmatism.

Taking off our medical intelligent mechanical exoskeleton, the patient is still paralyzed. I want to make this point clear to everyone, so as to avoid misunderstanding by patients or viewers and avoid unnecessary misunderstandings.

So how does our medical intelligent mechanical exoskeleton make patients with lower limb paralysis stand up? "

After throwing out this question, Wu Hao didn't answer in a hurry, but walked to the edge of the stage and took a bottle of water from the on-site staff, then unscrewed it and walked towards the middle of the round table.

After taking a sip of water, he continued to face everyone in the audience and said: "First of all, our medical intelligent mechanical exoskeleton acts as an external support for the lower limbs of the human body, including the torso.

And this kind of external support can reduce or even get rid of our body's own muscle and bone support system.

In other words, we can stand up without relying on the patient's lower limbs, relying solely on medical intelligent mechanical exoskeleton.

Because the medical intelligent mechanical exoskeleton is tied to the patient's paralyzed legs and torso, the medical intelligent mechanical exoskeleton will naturally drive our patient's body to move in sync while moving.

This is the basic principle of our medical intelligent mechanical exoskeleton. It seems very simple, but in fact it involves many technical fields. Each of these technologies may affect the success or failure of this medical intelligent mechanical exoskeleton and the final wearing experience.

And this is only the part of the support system, and the next more difficult part is its transmission system.

The transmission system on the entire medical intelligent mechanical exoskeleton is equivalent to the joints and muscles of the human body, which has the ability to drive the movement of the limbs.

And our transmission system is the same, it drives the medical intelligent mechanical exoskeleton to move.

This means that first it must be flexible enough to move freely, just like our limbs.

Secondly, it is strong enough. The weight of the entire medical intelligent mechanical exoskeleton, and even the weight of the entire human body, will directly or indirectly act on these transmission devices.

If the entire transmission device is not strong enough, it may be directly damaged, and it is not reliable and safe enough. Especially when walking on some more dangerous roads or doing some sports, it is likely to cause dangerous injuries to the wearer.

Finally, there is the aspect of power. Our muscles can burst out with strong power after accumulating energy, so this transmission system needs the same.

How to realize the ability of our human muscles to store energy quickly, have strong explosive force, and can continue high-definition sports, which requires a transmission device with strong performance to meet this requirement.

These three points seem to be very simple, but they actually cover many frontier fields of science and technology, such as materials science, mechanical engineering, electronic engineering, intelligent control and so on.

Only after the technologies and problems involved are overcome one by one, we can equip it on our medical intelligent mechanical exoskeleton to ensure its excellent performance and sufficient reliability. Only in this way can it meet the safety and practical standards of medical equipment, and can be used by paralyzed patients who are inherently fragile.

This is the support system and the transmission system, and then the most important control system. The difficulty of the entire control system lies in how to control the integration of the medical intelligent mechanical exoskeleton and the movement of our human body.

First of all, this control system must flexibly control the movement of the medical intelligent mechanical exoskeleton. Secondly, it also needs to adapt to the movement of our human body at all times and make adjustments at any time.

For these patients with lower limb paralysis, their lower limbs have no mobility. Therefore, we must find another way to allow paralyzed patients to control the entire medical intelligent mechanical exoskeleton to move without the lower limbs, thereby driving their lower limbs to exercise.

So how to control this set of medical intelligent mechanical exoskeleton for exercise, our engineers have thought of many ways.

Some people use intelligent voice control ~www.readwn.com~ Some people use artificial intelligence, and some people tend to use their hands to control.

In their words, these people are only paralyzed in their lower limbs, not even their hands are paralyzed, they can be manipulated with their hands.

However, this method was rejected by us. Because it is very inconvenient for these paralyzed patients to control with their hands, these patients' hands are used to control the medical intelligent mechanical exoskeleton, and they have no time to do other things.

Moreover, many patients are injured at a relatively high position, and it is difficult to use their hands, so it is not practical.

So we turned our attention to the bioelectric signal control technology that we used before on the smart robotic arm and smart bionic electronic prosthesis, which used motion bioelectric signals to control the smart robotic arm and smart bionic electronic prosthesis.

While introducing this technology, let us first understand how our brain controls our limbs to move. "
