Chapter 918 Redemption in the Dark World
This is the positioning basis for the entire operation, and its importance is self-evident.
Xu Qiu did it himself.
The patient sat.
The assistant fixed the stereotaxic base ring on the skull.
Then, the scalp at the fixation pin was routinely disinfected.
Then, 1% lidocaine combined with bupivacaine was used for local infiltration anesthesia.
Then tighten the fixing screw and insert the tip into the outer plate of the skull.
This step requires certain skills.
Once the fixation plane of the stereotaxic base ring coincides with the AC-PC plane, it is easy to produce artifacts.
The method adopted by Xu Qiu is very clever.
Keep the left and right directions of the base ring parallel to the orbital plane of both eyes, and the front and back are parallel to the AC-PC line. Keep the baseline of the front and back direction 2mm above the external ear canal and 3.5mm above the external ear canal, and then control this line and the auditory canal line to maintain an angle of ten to fifteen degrees to open backwards, so that it can be perfectly fixed.
After the head frame is installed, all steps of the implantation need to be carried out with the help of the head frame positioning.
The patient was then pushed to the CT room, where a more detailed positioning scan was obtained and preoperative monitoring was prepared.
Electrocardiogram, non-invasive blood pressure, blood oxygen saturation, PETCO2, etc. were loaded into the life monitor in turn.
At around ten o'clock in the morning, Chen Zhiyao was pushed into the operating room.
At this time, the outside world was surging, and countless cameras were aimed at this hospital located on the border of Linhai.
In the surgical team, the experts from Tiantan and Greentown First Hospital were somewhat uneasy.
They had never felt this level of attention before!
Everyone in Linhai kept a calm mind.
There was no way, Xu Qiu had done something more powerful than this before...
What complete fusion and separation of the brain and skull, sweeping the top ten in the world competition, there were simply too many to count.
"Calm down."
"Get used to it."
"We often encounter such things!"
Everyone in the Linhai medical team comforted the doctors from the other two hospitals.
Director Qiu of Tiantan rolled his eyes silently.
Do you know that you are so pretentious? Dr. Xu...
Director He also wanted to hit someone.
Those who don't know would think that these guys are the protagonists!
Amidst the curses, the team members entered the operating room one after another.
Not long after, another group of doctors speaking dialects from different provinces came in after completing the preoperative preparations.
After they changed into surgical gowns, they stood aside tacitly and chose a place that was most suitable for observation. Their eager eyes glanced at the airtight door from time to time.
"They are brain surgery experts from various provinces!"
The people in the surgical team recognized the identities of these people.
They had heard that each province would send people to observe.
Unexpectedly, it was true!
"It is said that Dr. Xu invited them here."
"Why ask them to come? There is nothing to join in the fun, right?"
"When you say this, can you please not take my best viewing position..."
"I don't know. Could it be that Dr. Xu wants to show off his muscles in front of doctors across the country?"
"Come on... Dr. Xu is not as shameless as you. Besides, with his level, does he need to show off his muscles? Wherever he stands, the hospital will be the national ace!"
"Who cares? Pay attention. So many people are watching. Don't hold Dr. Xu back!"
Amidst the murmurs, everyone's expressions became more serious.
Suddenly, the operating room fell into silence, and even the sound of tidying up the instruments disappeared.
Pairs of eyes looked at the airtight door at the same time.
Tsk——
The sound of exhaust was heard, and Xu Qiu walked in with an expressionless face.
He was calm and composed, without any emotional fluctuations due to the attention from the outside world.
It seemed that this was an operation that could not be more ordinary.
In fact, it was indeed the case for him.
In a place where no one could see, he worked like crazy in the simulated operating room, performed more than 60 operations, and gradually raised his rating to S+.
Not to say that he was confident, but he was almost certain.
"The results of the thin-layer scan have been transmitted to the workstation, and the target points for the three-dimensional reconstruction of the head image have been screened!"
The assistant of the imaging department reported.
Unlike other surgeries, implantation surgery has extremely high requirements for intraoperative image monitoring.
Preoperative MRI, thin-layer scan and other images need to be imported into special computing software to calculate the parameters of three-dimensional stereo positioning and confirm the location, depth, area, etc. of the surgical target.
The microelectrode mentioned many times during anesthesia has its significance here.
Its function is to achieve intraoperative electrophysiological positioning.
According to the preoperative imaging positioning, the surgeon needs to implant a temporary microelectrode into the patient's body to play the role of a pathfinder. It can directly detect the discharge of neuronal cells and then convert it into a signal that the doctor can see in the computer system of intraoperative detection.
The signals of different brain regions and different nuclei are different.
By identifying the characteristic signals of the target target, the surgeon can determine whether the pulse electrode has entered the target nucleus.
Of course, microelectrodes have another important function.
After implanting the electrode, the doctor can directly activate the pulse device to test the device's stimulation to the target point, and estimate the surgical effect by observing whether the patient's clinical symptoms have improved!
If the stimulation is effective, a permanent electrode can be implanted.
But if there is no improvement after pulse stimulation, the doctor should consider giving up the implantation, or temporarily placing the device, and observe the subsequent efficacy before making a decision.
This is why the anesthesia team is so concerned about microelectrodes.
That’s why Xu Qiu’s anesthesia plan amazed the anesthesia team!
Only the awake anesthesia plan planned by Xu Qiu can take into account both microelectrodes and intraoperative verification of patients!
…
Finally, Xu Qiu changed into surgical gowns and came to the main surgeon’s position.
Everyone’s nerves were also tense to the extreme.
However, when they saw Xu Qiu’s mask, their expressions were all stunned.
Cartoon mask…
What the hell!
“It’s because the patient is a child!” Soon, the director of clinical anesthesia realized the reason.
Many people felt ashamed.
They actually overlooked this point…
The patient was only eleven years old, and was awake anesthetized. During the operation, it is very likely that he will suffer tremendous mental pressure due to the doctor’s conversation, the collision of surgical instruments, the oppressive feeling of the environment, or the beeping prompts of the monitor.
In a serious environment, breaking into a cartoon element is indeed a great comfort to the soul.
“Hehe…” Sure enough, when Chen Zhiyao, who was looking around, saw the cartoon mask on Xu Qiu’s face, he could no longer look away, and his eyes narrowed with laughter.
Xu Qiu's voice softened, and he asked, "Have you seen this cartoon?"
"Yes! Bald Qiang always likes to chop trees, which is annoying."
"Then I made the right choice. I originally wanted to wear Peppa Pig, but then I thought you're so old now, you may not like watching Peppa Pig."
"I watch Peppa Pig, too!"
"What about Paw Patrol?"
"I like Maomao the most, even though he's always clumsy!"
Chen Zhiyao smiled so hard that his eyelashes curved, and his big eyes were filled with the spirit and innocence that belonged only to children.
Everyone in the operating room was stunned.
They stared blankly at Xu Qiu and Chen Zhiyao.
In a trance, they even forgot that this was in a dangerous operating room, but a normal daily life between a brother and sister...
