At this moment, Senior Brother Cao spoke to her, and it could be seen from the side that her current operation was indeed failing.
All I can say is that the big guys’ analysis of the rookies’ every move is always spot on.
What Senior Brother Cao said was right. If we analyze her behavior in detail, the first conclusion would definitely be that her brain is hesitating because of fear.
Why is her brain afraid? This fear should be attributed to the genetic genes of human ancestors or the habits developed since childhood: the habitual fear reflex to new things.
Do you think a person would be afraid if he suddenly saw his hand turn into an elephant?
If humans want to overcome this innate defense mechanism against new things in daily life, an effective way is to exercise the brain, let the brain adapt to new things, let the brain form new cognition, and there is no need to be afraid after knowing that this thing does not harm the human body itself.
The biggest problem at this stage is that there is not enough time for her to fully adapt during the operation.
After Senior Brother Cao pointed out her soul-destroying question, Senior Brother Huang took pity on her as a rookie and reminded her, "If you feel like you can't see clearly, you can adjust the focus."
These are general tips for using a surgical microscope.

One of the most significant differences between a surgical microscope and other types of microscopes is that it is designed to serve the doctor's hands. Therefore, the higher the magnification, the better. Instead, it should be just right to adapt to the doctor's eye-hand coordination.
Adjusting the eyepiece magnification, focal length, and the distance and angle between the moving lens barrel and the surgical field can all help doctors achieve a more consistent comfort zone for eye-hand coordination during surgery.
To be honest, the fine-tuning that Brother Huang mentioned is not completely useless, but it is more useful for masters who have already mastered the micro-manipulation. It cannot solve the most basic hand-eye coordination problem of novices.
Senior Brother Huang was a very nice person. He gave her advice without hesitation: "If you feel your eyes are tired from looking at the lens tube, you can look away and look at the big screen."
First of all, the human eye will experience visual fatigue if looking at a microscope for a long time. It would be best if you can reduce the time spent working under a microscope. The so-called electronic screen in the neurosurgery operating room is the navigation system mentioned earlier.
In order to allow this navigation system to see the surgical scene, it is possible to add a tiny camera to the surgical instrument and connect it to the navigation system. When the surgical instrument with its own camera enters the brain, it can record the surgical operation scene in real time, just like a laparoscope entering the human abdominal cavity. The resulting image is magnified on the navigation system's computer display, and everyone can watch the entire process as if they were watching a laparoscopic monitor.
At present, surgical instruments have not entered the brain. What Brother Huang is referring to should be the high-definition video system that comes with the surgical microscope. The electronic screen image of this system is the image recorded by the microscope eyepiece.
Xie Wanying was grateful for Brother Huang’s support, but:...it’s useless.
Because the above-mentioned techniques, to be honest, are only temporary solutions and do not address the root cause. Just like a microscope only magnifies the surgical scene, it cannot solve the basic hand-eye coordination problem of novices.
Huang Zhilei received a sharp glance from Senior Brother Cao: What's going on in your head?
Feeling annoyed by his senior brother’s nagging, Huang Zhilei turned around and looked at the "cat" beside him: Can you give me some advice? Haven’t you always supported my junior sister?
The little idiot senior got lazy and couldn't think of anything, so he just stopped thinking.
