If you try a surgery that no one has ever done before from the beginning, you may end up not being able to cross the river by feeling the other person's stones, which would be a greater risk.
The cost of a failed operation is too high, so safety must be put first.
"Well. Do you think you can do it?" Ren Zhelun asked.
"Brother, since you asked me, of course I can do it." Xie Wanying replied.
Mi Siran and the others were once again glad that they did not interrupt, because they almost misunderstood their leader's meaning again.
What Mr. Ren asked was not who could perform this operation, but whether K could achieve 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 feel that you are not as good as others?"
Others could feel that Mr. Ren’s question was becoming more and more “outrageous”. He was not asking a medical question, but a machine engineering question.
If a medical giant wants to make real innovations and go down in history, it is impossible for him to limit his discussion of medical issues to the scope of medicine. He must also discuss issues in the intersection of medicine and other disciplines.

For example, at the last closing meeting, a bunch of big guys were researching artificial vascular materials, and most of the issues they discussed were not purely medical.
Xie Wanying spoke objectively about the flaws: "There are definitely areas where we are not as good as others, for example, the structure of the robotic arm is not as good as theirs."
Designing a robotic arm is not as simple as connecting a few sticks together and making it move. Instead, it is necessary to consider factors such as the load-bearing force, rotation speed, rotational inertia, etc. of each part to allow the "sticks" to move accurately.
The design of a robotic arm needs to be similar to that of a surgeon in performing an operation. This is often referred to as bionics.
The human hand is not simply a few sticks connected together. There are so many bones from the upper arm to the fingers, so many muscle groups, so many joints, and the nerves and blood vessels that control them are networked, and there are as many as you want. It must first connect 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 automatic floating of the arm. After pressing the hand on the wall for 40 to 60 seconds, the hand naturally drops and the arm rises again. The seemingly strange signs seem to be controlled by ghosts, but in fact it is an involuntary movement of the human body. If you look deeper, you will find that the signal sent by the brain needs to have a decay process before it goes out. It can be understood as the damping phenomenon of "inertia" that the human body has.
The movement of the robotic arm belongs to the movement of objects. Anyone who has studied physics knows that objects have inertia when they move, and it is not easy to make an object stop suddenly and completely.
Looking at the reason why the robot arm repeatedly hit the arm when Dr. Lin Hao was operating it just now, it cannot be said that it was all Dr. Lin Hao's fault. Because the machine is made to lower the threshold for use, Dr. Lin Hao is not bad in terms of brain and hands-on ability, and is a surgical master. The fact that Dr. Lin Hao had difficulty using it shows that there is something wrong with the machine.
In fact, she observed that if Dr. Lin Hao had started using company B's products, perhaps such a bad situation would not have occurred.
Referring to the human body, not everyone has the Konstam phenomenon. This is because people have a powerful brain that can send inhibitory signals to the limbs. Some people cannot completely relax, so the experiment fails.
Another special situation is when something goes wrong with the brain. For example, in patients with Parkinson's disease, the brain signals are abnormal, resulting in severe Konstam phenomenon and unstoppable involuntary shaking.
If it is placed on the robotic arm, the electronic control system will shake constantly if it is not working. Just now, the situation is the opposite, and the electronic control system is normal.
When Ren Zhelun heard this, his face changed.
