Chapter 3680【3680】God-like organ
Because the skin is really a human organ, the largest organ of the human body, with a very complicated structure.
How complex, such as our skin can feel the sensation, can be traced back to all kinds of strange sensory cells in the skin. These sensory cells often astonished medical scientists in the scientific circle, just because they are so powerful, they are the masterpieces of the Creator, and they cannot be replaced by random inventions.
Among the sensory cells of the human body, the well-known Meissner corpuscles related to the sense of touch and pressure are mainly concentrated in the fingertips, tongue and lips, and can distinguish the touch of one hundred thousandth of a gram and the extremely low frequency of one hertz. frequency.
One gram weighs a lot, the weight of a peanut, the human skin can feel the touch of one hundred thousandth of a peanut, isn't it a good god? The human body is actually supernatural.
It’s just that this is not enough to summarize the magic of the skin. What can people embarrassingly associate with the above description of Meissner bodies? It is love caress.
Meissner's small body can feel whether your touch is pretending to love me.
This?
It turns out that the skin contains divine knowledge?
Are you saying this is something a machine can do?
Junior Mi Wenlin considers another physics concept "force". Force is actually a kind of interaction, and interaction often involves motion. You can go back and review Newton's three laws of mechanics in the physics textbooks in middle school.
In the sensory cells of human skin, the Pasini corpuscle is related to movement, which can feel the movement of one ten-thousandth of a millimeter. Therefore, people can feel it immediately without moving a toothpick on any surface.
Such human perception, if compared with a machine, the machine is undoubtedly a waste.
Laparoscopy is a tool, and the robotic arm is also a tool, which really cannot reach the level of human horror perception. For endoscopy, the operating lever is like holding a fishing rod and chopsticks to the doctor, and there are not too many links in the middle to make the force "transmission" simple and smooth. Surgical robots have too many mechanical arm joints, and various joint activities complicate the force. It is impossible to simply "transmit" the force at the head end to the doctor's hand for perception.
Ms. Chang said that the spine surgery department can be divided into neurosurgery classification, which involves the important human nervous system. The major pain point of neurological surgery has been mentioned many times before, and a little accidental touch will directly disable the patient.
I am afraid of accidental touch during the operation, it is best not to touch it, don’t touch it, even if it touches it, it is best to know that it has been touched with a light touch, and avoid it immediately.
To achieve such a surgical goal, what can doctors rely on?
It relies on the perception cells in the human body that have mysterious and terrifying power.
Does this mean that the machine will never be able to achieve the sense of touch?
Neither. The laws of mechanics are there. It is also possible to use the action of force to measure force, and to feel the sense of touch according to the action mechanism of human sensory cells. So she said, it's difficult, but it's not impossible, it's just that it needs a breakthrough in future technology for the machine to reach the level of the human body.
"Yingying, at your level—" Chang Jiawei looked at her, thinking of what classmate Fu said last time when he brought someone back, he muttered who was stupid, "You should have been exposed to surgical robots, right? They two idiots, ask You asked the wrong question."
(Zhou Junpeng: I, I, I, I am so difficult.)
Senior Zhou asked her if she had touched Senior Brother Ren's robot, she definitely hadn't, and she didn't lie to Senior Zhou.
