Chapter 1591 If It Succeeds, It Will Be a Miracle! (Seeking a Monthly Ticket)

The main core of stereotaxic surgery is the need to use an orientation instrument.

The difficulty of Parkinson's surgery is also here.

Precise positioning is required, and orientation is used 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 still chose a small amount of general anesthesia.

Then use local anesthesia to maintain!

After all, such an operation needs to observe the patient's condition.

Moreover, during the operation, especially when performing target manipulation, it is necessary for the surgeon and the patient to work together.

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

Intracranial surgery under local anesthesia.

Think about it and feel full of challenges!

but……

The reality is so cruel!

Therefore, such a surgery with precise control of anesthesia is still very difficult!

Even Chen Cang was still a little apprehensive about this operation!

After all, risk is something that is always around.

If it was in ancient times, before the operation, three sticks of incense must be offered to Master Hua Tuo, and then start!

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

Wu Hui nodded, eager to try.

Chen Cang admires Wu Hui very much, that is, he never hesitates in what should be done.

Dare to act can make a difference!

How can we achieve one side by shrinking our heads?

In the past two days, Wu Hui basically played with the orientation finder except for sleeping.

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

You don't need to worry about those annoying things anymore.

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

He is hungry for success!

I hope to be a superhero in the hearts of children.

Standing in front, he adjusted Zhou Hongguang's head so that the earplugs on both sides of the frame were aligned with the external auditory canal, and the midline of the skull was aligned with the center hole at the front and rear of the frame, which is the centerline of the instrument.

Orientation is a great invention of neurosurgery!

There is no doubt about this.

After some precise operations by Wu Hui, the head is located in the center of the frame in the front and rear direction of the head.

In fact, the installation of the extracranial orientation 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!

Also avoid the frame leaning back, leaning forward or rotating.

After Wu Hui has studied these few days, he has mastered it very well!

Chen Cang nodded: "Very good, perfect!"

Wu Hui stepped aside calmly.

At this time, Chen Cang started his own operation.

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

Then, a skull drilling was made in the center of the incision, the dura mater was incised in a "ten" shape, and then a spot of electrocoagulation was placed on the surface of the cortex to prepare for ventricle puncture and target puncture.

One of the more troublesome aspects of neurosurgery and orthopedic surgery is the need to frequently take photographs in the middle of the operation.

So much so that these orthopedic surgeons eat rays!

After all, you can't wear lead clothing during surgery. After all, how tiring is it to wear that thing after standing for such a long time?

And covered in sweat!

After Chen Cang completed these operations, ventriculography must be performed to display the positioning landmark structures such as the third ventricle, the interventricular foramen, the aqueduct, the pineal recess, and the anterior and posterior commissures.

This is a crucial step in directional surgery: ventriculography!

At this time, the director of the radiology department came over in person and nodded to Chen Cang.

Subsequently, the anterior horn of the lateral ventricle was punctured through the skull drilling, and pressure-filled ventriculography was performed or 10ml of positive contrast agent was injected.

This is a complex multidisciplinary operation.

Chen Cang didn't dare to be careless.

The hospital also attaches great importance to this.

Wu Tongfu came to the operating room this time wearing surgical gowns himself.

Hu Chuanbang from neurosurgery and Zhao Furun from neurosurgery came with him.

After they came in, they just saw the time when the contrast agent was injected.

The director of the radiology department said, "Everyone, dodge."

Everyone stepped back 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 for a while: "Half."

Wu Tongfu breathed a sigh of relief: "It's okay! Half of it is quite tall!"

Chen Cang hummed: "Either you succeed or you fail!"

Wu Tongfu was at a loss for words!

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

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

In fact, Chen Cang can't be blamed. The operation hasn't started yet, and the target location hasn't been determined yet. What's the success rate?

If only directional surgery were that easy!

But... Hu Chuanbang couldn't help but said: "Dean Wu, this is... Parkinson's surgery!"

Zhao Furun nodded: "That's right, if the Parkinson's surgery has a 50% success rate, Professor Chen may have a chance to hit the Nobel Prize!"

How many years does Parkinson's afflict the nervous system?

Everyone is unanimously stuck outside this gate, unable to move an inch.

How can it be that simple?

Wu Tongfu was taken aback for a moment before he realized it!

He said in a tone: "Don't worry about failure, come on!"

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

"Professor Chen, the film is out!"

Chen Cang's eyes lit up immediately: "Right away!"

After speaking, he glanced at Wu Tongfu and the others: "I'll go to the surgery first!"

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

Wu Hui followed closely behind.

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

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

This is Wu Tongfu rarely calling Chen Cang a child.

It was a year ago when this kid came to find him.

Comparing two by one, the changes are really too big!

"Yes!" Hu Chuanbang nodded.

Wu Tongfu sighed for a long time.

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

Success often means giving.

"He's only rested for a long time, and now he's devoted himself to Parkinson's research, hey..."

"I feel that compared with this kid, I am really too comfortable!"

Wu Tongfu couldn't help but sigh with emotion.

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

That's right, the two turned around and found that Dean Wu was staring at them.

Looking at the film in his head, Chen Cang couldn't help but praise: "Very good!"

Want to determine the landmark locations of the intracranial foramen, aqueduct, pineal recess, etc.

Films must be used.

And if you want to determine how to perform intracranial surgery and find the key target position, you need to combine the orientation instrument and the film, and then start to calculate!

And it's a precise calculation!

The target is the ventrolateral nucleus of the thalamus.

Because it has a significant effect on tremor and stiffness.

The medial globus pallidus has obvious effects on the stiffness and slowness of movement caused by Parkinson's, but it is normal for tremor.

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

How to locate?

It is particularly important!

Chen Cang had to lament the backwardness of the equipment. If MRI+PET+digital analysis technology could be used, it would be possible to precisely position and guide the surgery.

Even through the high resolution of nuclear magnetic resonance imaging (MRI) and thin-section scanning, images of deep brain structures in the basal ganglia region can be clearly displayed, providing conditions for direct and accurate positioning of targets.

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

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

It would be a miracle if it was successful.
