Yan Feifan used a marker to draw two small circles on the girl’s head, one above her left brow bone and another above her left ear.
Next, Dr. Qiu Ge’s assistant selected a suitable head clamp, adjusted the unconscious girl’s posture, and secured her body and head to the surgical chair.
Then, the assistant disinfected the marked areas and made incisions in the scalp with a scalpel.
Then, it was Yan Feifan’s moment.
He stood in the lead surgeon’s position that the assistant had cleared, first using a bone drill to open the skull, then performing the puncture with a long, thin Puncture Needle.
If any other doctor were performing this puncture, they would need to use a CT scanner to observe the depth of the Puncture Needle in real-time.
This was to prevent over-penetration or not reaching the target.
For Yan Feifan, however, this was an unnecessary step.
Thanks to the three-dimensional model generated in his mind’s eye, Yan Feifan knew the precise location of the blood clot.
He could also control the insertion depth of the Puncture Needle with perfect precision...
When the Puncture Needle had been slowly inserted to a depth of 9.53 centimeters, Yan Feifan stopped.
He withdrew the stylet from the Puncture Needle and then inserted a somewhat rigid, biocompatible tube through its hollow center, all the way to the bottom.
Then, Yan Feifan slowly withdrew the Puncture Needle, leaving the tube inside the girl’s brain.
This tube would remain inside the girl’s brain for about two days.
It was actually composed of two even thinner tubes.
One would deliver the medication inward, and the other would drain fluid outward.
After completing the first puncture, Yan Feifan immediately repeated the process for the second one.
At that moment, he noticed a blood-tinged fluid slowly flowing out of the drainage tube from the first puncture.
This was cerebrospinal fluid mixed with blood.
A puncture would inevitably damage some tiny blood vessels in the brain, so this level of bleeding was normal.
Having completed the punctures, Yan Feifan had to remain there to closely monitor the girl’s vital signs and the amount of cerebral bleeding...
A little over ten minutes later, Dr. Qiu Ge suddenly spoke up. "Mr. Yan, what about that sound hypnosis experiment from last time?"
"Oh, I’ve asked someone to break down the frequency and melody of that sound."
Yan Feifan explained, then added, "They also need to create a program to synthesize frequencies and melodies according to my specifications. They said it’s a bit complicated."
"It won’t be finished until next week."
Qiu Ge let out a soft "oh," then suddenly asked, "Mr. Yan, have you ever thought about taking on a few students or assistants?"
Without even thinking, Yan Feifan demurred, "Dr. Qiu, I’m still a student myself. How could I possibly take on students?"
"Besides, the few skills I have aren’t something that can be taught."
Qiu Ge thought about it and realized it was true.
Yan Feifan’s puncture and injection technique was a combination of his refined grasp of human anatomy and his incredibly delicate handiwork.
These were genuine, fundamental skills that couldn’t be taught.
Thinking of this, Qiu Ge suppressed the little scheme he had been considering.
The two of them observed for another forty-something minutes. Seeing no issues with the girl, they let the assistant handle the subsequent procedures.
Yan Feifan and Qiu Ge still had to go to the adjacent operating room to perform a similar puncture surgery on Qin Lang...
