Chapter 1591

When I was a child, there was a saying called: learn mathematics, physics and chemistry, go all over the world are not afraid!

Now these doctors here have big faces!

Chen Cang reported the coordinates from time to time:

"X-axis = 14mm, Y-axis = 4 ~ 5mm, z-axis = 0."

"Well, measure the front and rear (Y-axis), up and down (Z-axis) and inner and outer (x-axis) distances from the target point to the origin or central ray point of the instrument!"

……

Wu Hui quickly adjusted the orienteer.

The nurse here was not idle. What Chen Cang said was honestly written on the whiteboard behind him.

The whole process is really complicated.

calculation!

Measure!

……

Chen Cang felt his head huge at every step.

At this time, Chen Cang found his deficiency: insufficient computing power!

My memory has indeed made a qualitative leap with the emergence of the talent of never forgetting!

But... Computing power, um, is still the level of the original PE teacher!

Otherwise, I would have been admitted to Peking Union Medical College.

Chen Cang sighed with emotion!

However, there is a natural way to force.

For example, the sense of space of four-dimensional graph!

Chen Cang can clearly and accurately grasp the position of ventromedial nucleus of thalamus with the help of film and orientation instrument!

But

Naturally, it is impossible to learn an operation by yourself, right?

Chen Cang hesitated for a long time, but still felt that the instrument must be improved.

Otherwise, in the future surgery, we have to bring a mathematician to calculate on the spot.

indeed!

Looking at a group of numbers like geometric equations on the whiteboard, I was at a loss!

it's too hard!

We are surgeons. How can we study mathematics?

Wu Tongfu, on the other hand, was lost in thought. Should he put forward a suggestion at the next CPPCC meeting: should medical students increase mathematics courses?

Thinking of this, Wu Tongfu was frightened for fear that he would be executed by his group of graduate students.

After all, medical students have become tired dogs. If you add another math, don't live!

At this time, Chen Cang reported the point.

He has accurately obtained the coordinates of the target.

At this time, Wu Hui also quickly adjusted the orientation instrument.

Adjust the three coordinate axes of the orienteer according to the target coordinate data, that is, move the coordinate origin of the instrument sideways, forward and backward, up and down.

After adjustment, Chen Cang hurriedly said, "OK! Don't move!"

At this moment, the coordinate origin coincides with the target.

In this way, Chen Cang can conduct guided puncture through the surgical instrument carrier set on the spherical surface of the bow frame, and the needle can reach the target accurately at any point!

This is the core charm of directional surgery.

There are too many restricted areas in the brain.

It is very difficult to arrive smoothly. Therefore, such a neurosurgical directional operation that can reduce injury and accurately control came into being.

Here, Chen Cang looked up at the anesthesiologist: "teacher Zhou, how long will it take?"

Zhou he blurted out: "almost, just a few minutes!"

Anesthesiologists must be more accurate about the dosage.

In particular, this time limited general anesthesia.

Many operations require general anesthesia in order to prevent patient intolerance during disposal!

Chen Cang nodded: "prepare for local anesthesia."

Zhou He nodded.

Time goes by!

About three minutes later, Zhou Hongguang suddenly opened his eyes!

Wake up!

He stared at Chen Cang: "I... am I ok?"

Chen Cang smiled: "the operation has just begun!"

Zhou Hongguang said vaguely, "this anesthetic is very strong. I've been sleeping all day."

Anesthesiologist Zhou he said seriously, "you have to sleep as long as I let you sleep, otherwise... It's my dereliction of duty."

Chen Cang couldn't help laughing.

in truth.

After local anesthesia, Chen Cang did not delay and continued to start the operation!

When the brain needle enters slowly and reaches the ventromedial nucleus of thalamus, that is, the target.

Chen Cang suddenly asked, "director Zhou, what did you eat yesterday morning?"

Zhou Hongguang was speechless: "when did you ask me this question!"

At this time, Wu Tongfu was also in a panic!

Hu Chuanbang and Zhao Furun behind him said in one voice: "Dean Wu, don't be nervous!"

"This is Chen Jiashou testing director Zhou's neurological function!"

Wu Tongfu was relieved!

Zhou Hongguang couldn't help saying, "bean curd, fried dough sticks!"

Chen Cang said, "sweet and salty?"

Zhou Hongguang felt a chill!

However, the skulls are up. It's strange that they can't be cold!

Zhou Hongguang couldn't help saying, "you... This is the problem of war!"

Well, clear consciousness, clear consciousness, normal mental function!

Even Yinzhan posts can be distinguished clearly.

not bad

The success rate of operation is a little higher!

Then, Chen Cang said to Wu Hui, "check the nerve function, check the eyes first, and reflect the light..."

About five minutes, Zhou Hongguang is very cooperative!

"Normal nerve function!"

Chen Cang nodded: "OK!"

After saying that, Chen Cang held the brain needle here.

Ready to discharge!

At this time, Chen Cang hopes that his [beautiful eye] can become a [perspective eye]!

After all, it's too difficult to do blind exercises like this!

"Prepare for the first electrical stimulation and observe nerve function!"

"Do a good job of monitoring!"

"Ready to start!" Wu Hui said quickly.

Chen Cang nodded, the brain needle in his hand manipulated the switch, and immediately discharged!

During the operation, the most difficult place is to stimulate and destroy the targeted focus again and again.

Difficult to grasp!

Chen Cang didn't dare to exert himself every time. He had to control it carefully.

and!

Wu Hui here also needs to constantly pay close attention to and observe the patient's response and clinical effect!

It is very important to strive for satisfactory curative effect and prevent complications.

Brain acupuncture can't have any deviation!

Otherwise, the symptoms will not be relieved, and even... There are many unexpected complications!

Chen Cang's palms are sweat!

The brain needle didn't move!

Seeing Chen Cang's situation, Wu Tongfu and others behind him were all nervous and uneasy!

Silently begin to bless!

"Come on!"

But!

Just then, Wu Tongfu suddenly twitched at the corners of his mouth!

The nurse on one side suddenly opened her eyes.

Even Wu Tongfu and others looked serious!

There is a problem at this time, but it is very troublesome!

Even Hu Chuanbang and Zhao Furun have unconsciously pulled up their hands.

Too nervous!

And now!

Wu Hui was surprisingly calm, because Professor Chen had explained clearly before the operation, and many complications were well known. He hurriedly said:

"Professor Chen, there he is. The corners of his mouth twitch!"

Hearing the sound, Chen Cang hurriedly said, "prepare sedative drugs!"

"Wake up!"

It is best not to use sedative drugs or less during operation to keep the patient highly awake and cooperative.

But after this happens, we must control it!
