When a doctor opened a plug-in

The main core of stereotactic surgery is the need to use a directional instrument.

The difficulty of Parkinson's surgery is also here.

Need precise positioning, with the help of orientation to find surgical targets for stimulation or other operations.

Chen Cang actually considered at the beginning whether to use local anesthesia.

But after repeated attempts, I chose a small amount of general anesthesia.

Use local anesthesia to maintain!

After all, such an operation requires observation of the patient's condition.

Moreover, during the operation, especially when the target is controlled, the surgeon and the patient need to work together.

And it is necessary to constantly observe the patient's condition to judge the operation.

Intracranial surgery under local anesthesia.

Thinking about it, I feel full of challenges!

but……

The reality is so cruel!

Therefore, such an operation with precise control of anesthesia is still very difficult!

Even Chen Cang is still a little nervous about this operation!

After all, things like risk are always at the forefront.

If you stay in ancient times, you must give Master Hua Tuo three sticks of incense before the operation, and then start!

Chen Cang said to Wu Hui, "Come on?"

Wu Hui nodded, eager to try.

Chen Cang admired Wu Hui very much, that is, he never persuaded him to do things.

Dare to do something to make a difference!

How can one side be achieved by shrunken head and brain?

In the past two days, Wu Hui has been playing orienteering except for sleeping.

I have to say that after half a year of separation from my wife, I have a lot more time.

There is no need to entangle those annoying things.

The only difference is that I need to take custody as soon as possible!

He is eager to succeed!

I hope to be the superhero in the children's heart.

He stood in front and adjusted Zhou Hongguang's head position so that the earplugs on both sides of the frame were aligned with the external auditory canal, and the center line of his head aligned with the center hole of the front and back of the frame, which was the center line of the instrument.

Orientation instrument is a great invention of neurosurgery!

There is no doubt about this.

After Wu Hui's precise manipulation, his head was located in the center of the frame in the front and back direction.

In fact, the installation of the extracranial directional instrument does not seem to have any technical content, but in order to eliminate positioning errors as much as possible, it is still very particular!

At the same time, avoid tilting back, tilting or rotating the frame.

After studying in the past few days, Wu Hui still has a good grasp!

Chen Cang nodded: "Very good, perfect!"

Wu Hui stepped aside quietly.

At this time, Chen Cang started his own operation.

He took the scalpel and made a 4cm longitudinal incision 2.5cm next to the midline of the surgical side before the coronal suture.

Subsequently, a skull drill is made in the center of the incision, and the dura is cut in a "cross" shape, and then electrocoagulated on the surface of the cortex to prepare for ventricular puncture and target puncture.

One of the more troublesome aspects of surgery in Shenwai and Orthopedics is the need to take pictures frequently during the operation.

So much so that these orthopedic doctors eat rays!

After all, you can't wear lead clothes for surgery. After all, how tired is it to wear those things after standing for such a long time?

And covered in sweat!

After Chen Cang has done these operations, he must use ventriculography to show the third ventricle, interventricular foramen, aqueduct, pineal recess, anterior and posterior commissure and other positioning signs.

This is a key step in directional surgery: ventriculography!

At this time, the radiology director personally walked over and nodded to Chen Cang.

Then, the anterior horn of the lateral ventricle was punctured through the skull, and pressure-inflated ventriculography was performed or 10ml of positive contrast medium was injected.

This is a complex multidisciplinary surgery.

Chen Cang did not dare to be careless.

The hospital also attaches great importance to this.

This time Wu Tongfu came to the operating room in a surgical gown himself.

Hu Chuanbang of Neurosurgery Department and Zhao Furun of Neurology Department also arrived with one of them.

After they came in, they just saw the contrast agent hitting it down.

The director of the radiology department said: "Everyone dodging."

Everyone retreated to behind the screen.

Wu Tongfu looked at Chen Cang and couldn't help asking: "How sure are you?"

Chen Cang looked at the nervous Dean Wu and thought about it: "Half."

Wu Tongfu breathed a sigh of relief: "Fortunately! Half of it is quite tall!"

Chen Cang said, "Either succeed or fail!"

Wu Tongfu was speechless!

I really want to pick up a knife and draw a capital "Z" on Chen Cang.

Your sister, what am I nervous like, are you humorous with me?

Actually, Chen Cang can't be blamed. The operation has not started and the target location has not been determined. What is the success rate?

If directional surgery is really so simple, it would be great!

But... Hu Chuanbang couldn't help saying: "Dean Wu, this is...Parkinson's operation!"

Zhao Furun nodded: "Yes, if Parkinson's surgery has a 50% success rate, Professor Chen might have a chance to hit Nobel!"

How many years has Parkinson troubled the nervous system?

Everyone was stuck outside this gate, making it difficult to move.

How can it be that simple?

Wu Tongfu was taken aback, only then did he react!

He talked: "Don't worry about failure, come on!"

Here, after the radiography was finished, the director of the radiology department issued a report very quickly, very quickly and accurately!

"Professor Chen, the film is out!"

Chen Cang's eyes lit up suddenly: "Immediately!"

After that, I glanced at Wu Tongfu and others: "I'll go for surgery first!"

After speaking, I couldn't wait to walk outside.

Wu Hui followed closely.

And Wu Tongfu looked at Chen Cang's back and suddenly became silent:

"Chen Cang, this child...too hard work!"

This is what Wu Tongfu rarely calls Chen Cang a child.

When this kid came to find himself, it was a year ago.

Comparing two by one, the change is really big!

"Yes!" Hu Chuanbang nodded.

Wu Tongfu sighed for a long time.

How great the honor is, how difficult is behind it!

Success often means giving.

"How long did he take a rest? In a blink of an eye, he invested in Parkinson's research, hey..."

"I think compared to this kid, I'm really too comfortable!"

Wu Tongfu couldn't help but sigh with emotion.

The other two blushed, how could they suddenly feel that Wu Tongfu was talking about themselves.

Yes, the two turned around and found that Dean Wu was staring straight at them.

Chen Cang looked at the film in his skull and couldn't help but praised: "Very good!"

Want to determine the iconic positions of the intracranial interventricular foramen, aqueduct, pineal recess, etc.

Must use film.

If you want to determine how to perform intracranial surgery and find the key target location, you need to combine the orientation instrument and the film, and then start the calculation!

And it is a precise calculation!

The target was the ventrolateral nucleus of the thalamus.

Because here has a significant effect on tremor and stiffness.

The inside of the globus pallidus has a significant effect on the stiffness and retardation caused by Parkinson, but it has a general effect on the tremor.

However, it is more difficult to locate the ventrolateral nucleus of the thalamus than to find the medial side of the pallor.

How to locate?

It is especially important!

Chen Cang had to sigh with the backwardness of the instrument. If MRI+PET+digital analysis technology can be used, it can accurately locate and guide surgery.

Even through the high resolution of nuclear magnetic MRI and thin-slice scanning, images of deep brain structures in the basal ganglia can be clearly displayed, which provides conditions for direct and accurate target positioning.

But, on this condition, what kind of bicycle do we want?

Chen Cang can only use the most primitive technique to perform this operation.

If it is really successful, this would be a miracle.
