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 finding 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 connecting 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 surgical results that are not consistent with the theory.
The specific reason is that the head is not flat, but three-dimensional.
The two-point connection between 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. When analyzed in imaging and in 3D software, the image can be abstracted and countless obstacles in the middle can be ignored.
.In actual practice, doctors’ eyes cannot achieve precise visual inspection as 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 someone can really do what was calculated theoretically, and the effect was amazing. The biggest role in this was that anyone with a discerning eye could see who it was.
"Her eyes have powers."
(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 Xie can analyze the three-dimensional human body in reality into three-dimensional points, and this kind of insight is unmatched. Therefore, the choice problem that Dr. Charlie was worried about at the beginning was not a problem at all for Xie Wanying.
Is this all her ability? Dr. Tong’s cool eyes were silent.
After having his brain touched by Xie himself, his experience should be deeper than that of foreigners.
Correctly identifying the line connecting two points is a major factor, but don’t forget that after correctly identifying the line, the doctor needs to operate on a comfortable surface, otherwise, everything will be in vain.
It is reflected in the previous steps that positioning the body and head is very important.
To put it simply, Xie Wanying is an assistant. If she wants to help the surgeon achieve the above goals, she must first feel the brain of the surgeon, know where the comfortable level is for the surgeon, and position the patient's head to a level suitable for the surgeon's operation.
Cao Yong felt mixed emotions because of her habit of touching his hands. On the one hand, he thought that it was no wonder that all the people she had passed through before liked to partner with her. On the other hand, being chased by a junior like her,
He is also stressed.
Dr. Charlie continued to ask Dr. Tong for preoperative 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 only know that it may be effective. Whether it is really effective will only be known after the operation, such as the positioning just now.
Outside the operating room, someone was brushing their hands.
Student Wei looked outside, glanced at the person washing hands in the surgical department, 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 thought about it.
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.
