Chapter 3680 [3680] God-like organs

Previous page        Return to Catalog        Next page

    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 various strange sensory cells in the skin.  These sensory cells often shock medical scientists in the scientific community because they are so powerful that they are creations.

    The Lord¡¯s masterpiece cannot be replaced by a random invention.  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.

    One gram weighs as much as one 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 amazing.

    But this is not enough to summarize the magic of skin. What can the description above about Meissner's corpuscles make people ashamed to think of it?  It is a love caress.

    Meissner's corpuscle can feel whether your touch is pretending to love me.

    this?

    It turns out that the skin contains divine knowledge?

    Do you think this can be done by a machine?  Another physics concept that junior brother Mi Wenlin considers is "force". Force is actually a kind of interaction, and interaction often involves motion.  You can go back and review Newton¡¯s Mechanics III from the physics textbook in middle school.

    The big law.  Among the sensory cells of human skin, the ones 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 you compare this kind of human perception with a machine, the machine is undoubtedly a waste.  The endoscope is a tool, and the robot 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 to "conduct" the force.

    ? 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.  One of the major pain points of neurological surgery has been discussed many times before. A slight mistake can directly cause the patient to suffer.

    People are 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 just touch it lightly and avoid it immediately.

    To achieve such a surgical goal, what can doctors rely on?

    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?  Not really.  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, it's difficult, but it's not completely impossible.

    , but for the machine to reach the human level, it really needs a breakthrough in future technology.  "Yingying, at your level -" Chang Jiawei looked at her, thinking of what Mr. Fu said after bringing someone back last time, and muttered who was stupid, "You should have been exposed to surgical robots. They are two idiots,  ask you questions

    The question is wrong.  "

    (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, and she did not lie to Senior Zhou.  (Remember the website address: www.hlnovel.com
