Chapter 3738 [3738] Is It Wrong?

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 failed surgery is too high, so safety must come first.

"Well. Do you think you can do it?" Ren Zhelun asked.

"Senior brother, you 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 Boss Ren's questions are becoming more and more "outrageous". The non-medical questions he asked should be 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 the shortcomings in a matter-of-fact manner: "There are definitely areas where it is 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, rotation 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 similar to that of a surgeon when performing operations, much like our human hands. This is bionics that we often hear about.

The human hand is also not simply a few sticks connected together. There are as many bare bones from the upper arm to the fingers, as many muscle groups, and as many joints as there are nerves and blood vessels controlled inside. They are networked, and there are as many as there are. It must first be connected to the spine and then to the brain.

The linkage between the human brain and limbs has the famous Konstam phenomenon, which is called the arm automatically floating. After a person presses his hand on the wall for forty to sixty seconds, he naturally puts it down, and the arm rises again on its own. The strange signs appear to be controlled by ghosts, but are 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. It can be understood that the human body has the same "inertial" damping phenomenon.

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.

Looking back at the reason why the robotic arm repeatedly touched Dr. Lin Hao's arm during the operation just now, it cannot be said that it is purely Dr. Lin Hao's fault. Because the machine is made to lower the threshold for use, Dr. Lin Hao is a master of surgery in all aspects including his mental ability and hands-on skills. Dr. Lin Hao has difficulty getting started, indicating that there is something wrong with this machine.

In fact, she observed that Dr. Lin Hao might not be in such a bad situation if he used Company B's products.

Referring to the human body again, not everyone has the Constam phenomenon. This is because people have powerful brains that can send inhibitory signals to their limbs. Some people are unable to completely relax and this phenomenon is a direct failure of the experiment.

Another special situation is when there is a problem 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 a robotic arm, if the electronic control system fails, it will keep shaking. I just observed along the way that the situation is opposite and the electronic control system is normal.

Ren Zhelun's expression changed when he heard this.

Thank you for your support! ! ! Good night, dears~
