Chapter 1,159 How to make a paralyzed patient stand up
In fact, Wu Hao had already expected that many people would not believe his words before this. Therefore, he had already prepared relevant countermeasures for this.
Wu Hao pressed his hand slightly to stop the discussion in the audience, and then continued: "I know that everyone may have doubts about this, thinking that I am telling lies or exaggerating to mislead everyone.
But please rest assured that we dare to announce this news at such a formal conference, which proves that we are confident enough in our products."
Seeing that all the guests in the audience were quiet, Wu Hao secretly breathed a sigh of relief, and then continued: "There are many paralyzed patients, and there are many causes of paralysis, so I have selected the ones that everyone is most interested in and account for the most.
Let me give you an example by comparing a relatively large patient with lower limb paralysis.
There are many causes of paralysis of the lower limbs. There are two main common causes. One is paralysis of the lower limbs caused by brain diseases, such as intracerebral hemorrhage, which compresses motor nerves, resulting in paralysis of the lower limbs.
The other type is paralysis of the lower limbs caused by spinal lesions or trauma.
We also have relevant treatment plans for these two types, but because of the different causes, the 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 lesions.
I want to say something in advance here, 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 exercise ability.
This point is the same as the glasses we wear for nearsightedness, farsightedness or astigmatism. When you take off the glasses, you will still be nearsighted and your astigmatism will still be astigmatism.
Even if we take off our medical intelligent mechanical exoskeleton, the patient will still be a paralyzed patient. I want to make this clear to everyone to avoid misunderstandings by patients or viewers and avoid unnecessary misunderstandings.
So how does our medical intelligent mechanical exoskeleton allow patients with lower limb paralysis to stand up?"
After posing this question, Wu Hao did not rush to answer. Instead, he walked to the edge of the stage and took a bottle of water from the hands of the on-site staff. Then he unscrewed it and walked towards the center 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 human body's lower limbs, including the trunk.
This external support function can reduce or even get rid of our body's own muscle and bone support system.
In other words, we can not rely on the patient's lower limbs, but rely solely on the medical intelligent mechanical exoskeleton to support the person standing up.
Because the medical intelligent mechanical exoskeleton is tied to the patient's paralyzed legs and torso, when the medical intelligent mechanical exoskeleton moves, it will naturally drive our patient's body to move synchronously.
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 performance of this medical intelligent mechanical exoskeleton.
Success or failure, and the final wearing experience.
And this is only the support system part, 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 limb movement.
The same goes for our transmission system, which 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 that the weight of the entire medical intelligent mechanical exoskeleton, and even the weight of the entire human body, will directly or indirectly affect 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 dangerous road sections or doing some sports, it may cause dangerous injuries to the wearer.
Finally, in terms of power, our muscles can explode with powerful force after storing energy, so this transmission system also needs the same.
How to realize the ability of our human muscles to store energy quickly, have strong explosive power, and be able to sustain high-definition movements requires a transmission device with strong performance to meet this requirement.
These three points may seem very simple, but in fact they cover many cutting-edge fields of science and technology, such as materials science, mechanical engineering, electronic engineering, intelligent control and other disciplines.
Only after overcoming these involved technologies and problems one by one can we equip them on our medical intelligent mechanical exoskeleton to ensure that it has excellent performance and is reliable enough. Only in this way can we achieve the safety and practical standards of medical devices.
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 is how to control the integration of the medical intelligent mechanical exoskeleton with 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 movements 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 ability to move. Therefore, we must find another way to allow paralyzed patients to control the movement of the entire medical intelligent mechanical exoskeleton without using the lower limbs, thereby driving their lower limbs to move.
So how to control this medical intelligent mechanical exoskeleton to move, our engineers have thought of many ways.
Some say they use intelligent voice control, some say they use artificial intelligence, and some people prefer to control it with their hands.
In their words, these people are only paralyzed in their lower limbs, not even their hands. They can completely use their hands to control.
However, this method was rejected by us. Because it is very inconvenient for these paralyzed patients to control it with their hands. In this way, these patients' hands are used to control the medical intelligent mechanical exoskeleton, and they have no time to do other things.
Very inconvenient.
Moreover, many patients are injured at a relatively high position and have difficulty using their hands, so it is not practical.
So we focused our attention on the bioelectrical signal control technology that used motion bioelectrical signals to control intelligent robotic arms and intelligent bionic electronic prostheses that we had previously adopted.
While introducing this technology, let us first understand how our brain controls the movement of our limbs."
