Xie Wanying just instructed the surgeon that the direction of entry should be the line connecting the tip of the nose and the apex of the auricle as the direction line.
Such directional research on searching for the sphenoid sinus has been done in medicine. The main method is to use magnetic resonance to conduct a detailed analysis of the anatomical surface of the nasal bone and sphenoid bone and then draw a calculation conclusion.
It is said that according to this connection line as the direction line, the accuracy of finding the sellar floor through the sphenoid sinus is very high, and the penetration rate can reach 100%.
Theory is a theoretical thing, and actual operations often encounter obstacles, resulting in the failure to achieve results consistent with the theory during surgery.
The specific reason is that the head is not flat, but three-dimensional.
The line connecting the two points of the tip of the nose and the apex of the auricle is actually blocked by obstacles in the middle, such as the undulations of the face. Analysis in imaging and analysis in 3D software can abstract the image and ignore the countless obstacles in the middle. In actual practice, doctors' eyes cannot achieve the precise visual inspection abstracted by software.
Rough and approximate measurements will lead to insufficient accuracy, and the operation will definitely not be as accurate as planned. No one can achieve the perfect effect in theory.
However, the amazing visuals of the surgical team made people realize that there are really people who can do what was calculated theoretically, and the effect was astonishing. Anyone with a discerning eye can see who plays the biggest role in this.
"Hereyeshavepoers."
(Her eyes have super powers.)
This is what Dr. Charlie and a group of foreign colleagues saw with their own eyes. They sighed loudly. When they came to the scene and touched people's brains, they found that people's brains are really scary.
Foreigners believe that Mr. Xie can analyze the three-dimensional human body in reality into three-dimensional points. This kind of insight is unmatched by anyone. Therefore, the choice problem that Dr. Charlie was worried about at the beginning was not a problem at all for Xie Wanying.
Is that all she can do? Dr. Tong's cool eyes were silent.
After having his brain touched by Xie himself, his experience should be deeper than that of a foreigner.
Correctly identifying the line connecting two points is a major factor, but don’t forget that after identifying the line, the doctor needs to operate on a comfortable surface, otherwise, everything will be in vain.
This is reflected in the crucial importance of body and head position in the previous steps.
To put it simply, Xie Wanying is an assistant. If she wants to help the surgeon achieve the above goal, she must first feel the brain of the surgeon, know where the comfortable level is, and position the patient's head to a level suitable for the surgeon's operation.
Cao Yong was filled with mixed emotions because of her habit of touching his hands. On the one hand, she thought that it was no wonder that all the people she had passed through before liked to partner with her. On the one hand, being chased by a junior like her puts him under pressure.
Dr. Charlie continued to ask Dr. Tong for pre-operative discussions because he wanted to know whose brain it was.
Doctor Tong rejected him again and simply said: "It's useless."
It was useless, they couldn't understand what Xie Wanying said at that time anyway.
I just know it might work. Whether it is really useful or not will only be known after the operation, just like the positioning just now.
Outside the operating room, someone was brushing their hands.
Student Wei looked out and glanced at the man washing his hands in the surgical department. He turned around and said to other students, "He doesn't look good."
It is rare for Song Xuelin, who is known as a genius, to be so nervous. Pan Shihua and the others were thinking.
At this time, exclamations sounded again in the operating room and multimedia conference room.
Song Xuelin's hands, which were washed under the water of the faucet, stopped in mid-air.
