Military Technology

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

Slightly suppressing his hand to stop the discussion in the audience, Wu Hao continued: "I know that everyone may have doubts about this, thinking that I am talking big or exaggerating to mislead everyone.

But don't worry, we dare to announce this news at such an official press conference, which proves that we have enough confidence in our products. "

Seeing that the guests in the audience were all quiet, Wu Hao secretly breathed a sigh of relief, and then continued: "There are many paralyzed patients, and there are many reasons for the paralysis, so I picked out the ones that everyone is most interested in. Let me give you an example of a relatively large paralyzed patient.

There are many reasons for lower limb paralysis, and there are two common reasons. One is lower limb paralysis caused by intracerebral diseases, such as intracerebral hemorrhage, which compresses motor nerves and causes lower limb paralysis.

The other is paralysis of the lower limbs caused by spinal lesions or trauma.

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

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

This is the same as the myopia and hyperopia or astigmatism glasses we wear. After taking off the glasses, your myopia is still myopia, and your astigmatism is still astigmatism.

Take off our medical intelligent mechanical exoskeleton, the patient is still a paralyzed patient. I want to make this point clear to everyone, so as not to cause patients or audiences to misunderstand and avoid unnecessary misunderstandings.

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

After asking this question, Wu Hao didn't answer in a hurry, but went to the side of the stage to take a bottle of water from the hands of the on-site staff, then unscrewed it, and walked towards the middle of the round stage.

After taking a sip of water, he continued to face 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 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, and relying solely on the 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 synchronously while moving.

This is the basic principle of our medical intelligent mechanical exoskeleton. It seems 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, as well as the final wearing experience.

And this is only part of the support system, and the next more difficult thing 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, and it has the ability to drive the movement of the limbs.

The same is true for our transmission system, which drives the medical intelligent mechanical exoskeleton to move.

That means first it has to be flexible enough to move freely, like our limbs.

Secondly, it is strong enough that the weight of the entire medical intelligent mechanical exoskeleton, or 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 damaged directly, which is not reliable and safe enough. Especially when walking on some dangerous road sections or doing some sports, it is likely to cause dangerous injuries to the wearer.

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

How to achieve the ability of our human muscles to store energy quickly, have strong explosive power, and be able to continue high-definition movement requires a strong performance of the transmission device to meet this requirement.

These three points may seem simple, but they actually cover many frontier fields of science and technology, such as materials science, mechanical engineering, electronic engineering, intelligent control and other disciplines.

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

This is the support system and transmission system, followed by 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 should flexibly control the movement of the medical intelligent mechanical exoskeleton. Secondly, it also needs to adapt to the movement of our human body all the time and make adjustments at any time.

For this part of paralyzed patients, 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 using their lower limbs, so as to drive their lower limbs to exercise.

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

Some say to use intelligent voice control, some say to use artificial intelligence, and some people tend to use hands to control.

In their words, these people are only paralyzed in the lower limbs, not even their hands are paralyzed, they can completely use their hands to control.

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

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

So we put our attention on the bioelectric signal control technology that we used to use motion bioelectrical signals to control intelligent robotic arms and intelligent bionic electronic prosthetics.

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