If you try an operation that no one has done from the beginning, you may not be able to cross the river by touching the other person's stones, and the risk will be even greater.
The cost of a failed surgery is too high, so safety must come first.
"Hmm. Do you think you can do it?" Ren Zhelun asked.
"Senior brother, you have asked me, of course I can do it." Xie Wanying replied.
Misran and the others were once again glad that they did not interrupt, because they almost misunderstood the leader again.
What Boss Ren asked was not whether anyone could perform this surgery, but whether K could perform it to the level of Company B’s product.
Not being praised by Junior Sister Youtiao, Ren Zhelun continued to ask: "You just tried it, do you think it's not as good as others?"
Others can feel that Mr. Ren's questions are becoming more and more "outrageous". He is asking non-medical questions, but he should be asking machine engineering questions.
A medical leader who wants to be truly innovative and famous throughout history cannot only talk about medical issues within the scope of medicine. He must talk about issues that intersect with other disciplines.
For example, at the last closing meeting, a bunch of big guys were studying artificial blood vessel materials, and most of the issues discussed were not purely medical.
Xie Wanying talked about shortcomings realistically: "There are definitely areas where we are not as good as the other. For example, no one can do a better job with the structure of the robotic arm."
Designing a robotic arm is not just about connecting a few sticks together so that they can move. Instead, it is necessary to consider factors such as the load-bearing capacity, rotational speed, rotational inertia and other factors of each part to allow the "stick" to move accurately.
The design of the robotic arm needs to be more or less similar to our human hands in order to perform operations like a surgeon. This is bionics that we have often heard of.
The human hand is also not just a few sticks connected together. There are as many bare bones from the upper arm to the fingers, as many muscle groups, as many joints as there are. The nerves and blood vessels controlled inside are networked, and there are as many as there are. Above
First it needs to be connected to the spine and then to the brain.
The linkage between the human brain and the limbs has the famous Konstam phenomenon, which is called the automatic floating of the arm. After a person presses his hand on the wall for forty to sixty seconds, he naturally puts it down, and then the arm is raised again on its own. The seemingly weird sign seems to be caused by a ghost.
Manipulation is actually an involuntary movement of the human body. If you dig deeper, you will find that the signal sent by the brain needs to undergo an attenuation process before being extinguished. This can be understood as the same "inertial" damping phenomenon as the human body.
The movement of a robotic arm belongs to the movement of an object. Anyone who has studied physics knows that objects have inertia when moving. It is not easy to stop the object suddenly and completely.
Let’s look at the reason why the robotic arm repeatedly touched Dr. Lin Hao’s arm when he was operating. It cannot be said that it is purely Dr. Lin Hao’s fault. Because the machine was made to lower the threshold for use, and Dr. Lin Hao’s mental and practical abilities are not bad at all.
Even Dr. Lin Hao, a master of surgery, has difficulty getting started, which means there is something wrong with this machine.
In fact, she observed that if Dr. Lin Hao had used Company B's products, he might not have been in such a bad situation.
Referring to the human body again, not everyone has the Konstam phenomenon. This is because people have a powerful brain that can send inhibitory signals to the limbs. Some people are unable to completely relax. This phenomenon directly failed the experiment.
Another special situation is when there is something wrong with the brain. For example, in patients with Parkinson's disease, brain signals are abnormal, resulting in severe Konstam's phenomenon and involuntary shaking that cannot be stopped.
When placed on the robotic arm, if the electronic control system does not work, it will keep shaking. I just observed that the situation is the opposite, and the electronic control system is normal.
Ren Zhelun's expression changed when he heard this.
