Chapter 3680 [3680] God-Like Organs
Because the skin is really a human organ, it is the largest organ in the human body and its structure is very complex.
How complex it is, for example, the sensations we can feel on our skin can be traced back to all kinds of weird sensory cells in the skin. These sensory cells often shock medical scientists in the scientific community because they are so powerful. They are the work of the Creator and cannot be replaced by random gadgets invented by humans.
Among the human body's sensory cells, the most well-known ones related to the sense of touch and pressure are Meissner's corpuscles, which are mainly concentrated in the fingertips, tongue, and lips. They can distinguish touches of one hundred thousandth of a gram and extremely low frequencies of one hertz. frequency.
How much does one gram weigh? The weight of a peanut. Human skin can feel the touch of one hundred thousandth of a peanut. Isn’t it a good thing? The human body itself is actually quite extraordinary.
But this is not enough to summarize the magic of skin. What else can the description above about Meissner's corpuscles make people ashamed to think of? It is a love caress.
Meissner's corpuscle can feel your touch is it pretending to love me.
this?
Does the skin contain divine knowledge?
Do you think this can be done by a machine?
Another physical concept "force" that junior brother Mi Wenlin considers is that force is actually a kind of interaction, and interaction often involves motion. You can go back and review Newton's three laws of mechanics from the physics textbooks in middle school.
Among the human skin sensory cells related to movement are Pacinian corpuscles, which can sense movements of one ten thousandth of a millimeter. Therefore, if a person puts a toothpick on any surface, he can feel it immediately without even moving.
If we compare this kind of human perception with a machine, the machine is undoubtedly a waste.
The endoscope is a tool, and the robotic arm is also a tool. It really cannot reach the terrifying level of perception of the human body. In the case of endoscopic surgery, the operating rod is like a fishing rod or chopsticks to the doctor. There are not too many links in between, making the force "conduction" simple and smooth. The robotic arm of the surgical robot has too many joints, and various joint activities complicate the force. It is impossible to simply and accurately "transmit" the force from the head end to the doctor's hand.
The spine surgery department where Teacher Chang works has said that it can be classified into neurosurgery, which involves the important human nervous system. The major pain point of neurological surgery has been mentioned many times before. A slight mistake can directly cause the patient to become disabled.
During surgery, if you are afraid of accidentally touching something, it is best not to touch it. Even if you touch it, it is best to touch it lightly until you know it is touched, and avoid it immediately with your hands.
What can doctors rely on to achieve such a surgical goal?
It relies on the sensory cells in the human body that have mysterious and terrifying power.
Does this mean that machines will never be able to sense touch?
Nor is it. The laws of mechanics are there. You can use the action of force to measure force, and you can also feel the touch according to the mechanism of the human body's sensory cells. So she said that it is difficult, but it is not completely impossible. It is just that for machines to reach the human level, it still needs future technological breakthroughs.
"Yingying, at your level -" Chang Jiawei looked at her, thinking of what Mr. Fu said last time when he brought someone back, and muttered who was stupid, "You should have been exposed to surgical robots. They are two idiots, It’s the wrong question to ask you.”
(Zhou Junpeng: I, I, I, it’s so difficult for me.)
Senior Zhou asked her if she had ever come into contact with Senior Brother Ren's robot. She definitely had not. She did not lie to Senior Zhou.
