Because the skin is really a human organ, the largest organ in the human body, and its structure is very complicated. How complicated, like our skin can feel sensation, can be traced back to all kinds of weird sensory cells in the skin. These sensory cells often astound medical scientists in the scientific circle, because they are so powerful that they are created
The Lord's divine works 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 Hz. 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 hides divine knowledge
Are you saying this is something a machine can do? Another physics concept considered by the younger brother Mi Wenlin is "force". Force is actually a kind of interaction, and interaction often involves motion. You can go back and review Newtonian Mechanics III in the middle school physics textbook.
big law. In the sensory cells of the human skin, the movement is related to the Pasini corpuscle, which can sense the movement of one ten-thousandth of a millimeter. Therefore, people can feel it immediately without moving a toothpick on the surface of any object.
.
If this kind of human perception is compared with a machine, the machine is undoubtedly a waste. The endoscope is a tool, and the robot arm is also a tool, which really cannot reach the level of human horror perception. In the case of endoscopy, the operating rod 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 "transmit"
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. Mr. Chang’s department of spine surgery 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, and a little accidental touch will directly make the patient
Disabled.
I’m afraid of accidentally touching it during the operation, so it’s best not to touch it, don’t touch it, even if it touches it, it’s best to know it with a light touch, and avoid it immediately.
To achieve the purpose of such surgery, what can doctors rely on
It relies on the perception cells with mysterious and terrifying power in the human body.
Does this mean that the machine will never be able to achieve the sense of touch? Nor is it. 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 is difficult, but not impossible
, it’s just that the machine needs a breakthrough in future technology to achieve 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? These two idiots, ask your problem
Wrong question. "
(Zhou Junpeng: Me, me, me, I'm 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.
