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

And the difficulty of Parkinson's surgery is also here.

Accurate positioning is required, and targeting is used to find surgical targets for stimulation or other operations.

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

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

Afterwards, use local anesthesia to maintain!

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

Moreover, during surgery, especially when target manipulation, 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.

It feels challenging to think about it!

but……

Reality is so cruel!

Therefore, such an operation with accurate grasp of anesthesia is still very difficult!

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

After all, things like risk are always with you.

If it were put in ancient times, you must have three incense sticks for Mr. Hua Tuo before the operation, and then start!

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

Wu Hui nodded and was eager to try.

Chen Cang admires Wu Hui very much, that is, he is never timid in what he should do.

Only by daring to do can you make a difference!

How can you achieve success by shrinking your head and brain?

Wu Hui has been playing the directional instrument in the past two days except for sleeping.

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

There is no need to worry about those troubles.

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

He longs for success!

I hope to be the superhero in my children's hearts.

He stood in front and adjusted Zhou Hongguang's head position so that the earplugs on both sides of the frame are aligned with the external auditory canal, and the midline of the head is aligned with the central hole in the front and back of the frame, which is the midline of the instrument.

Directional instruments are a great invention of neurosurgery!

This is undoubtedly.

After Wu Hui's precise operation, the head is located in the center of the frame in the front and back directions.

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

At the same time, the frame should be avoided leaning back, leaning forward or rotating.

Wu Hui has learned this past few days and has mastered it very well!

Chen Cang nodded: "Very good, perfect!"

Wu Hui calmly moved away from his position.

At this time, Chen Cang started his own operations.

He took the scalpel and made a 4cm-long longitudinal incision 2.5cm beside the midline of the surgical side before the coronal slit.

Subsequently, a skull drill was performed in the center of the incision, the dura mater was cut in the shape of a "cross" and then electrocoagulated a little on the cortical surface for ventricular puncture and target puncture.

The more troublesome thing about the surgery in Septuaginal and orthopedics is that it requires frequent film shooting during the operation.

So many things happen to these orthopedic doctors about taking rays!

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

And she was covered in sweat!

After Chen Cang completed these operations, he had to use ventricular symptomography to display the third ventricle, interventricular hole, aqueduct, pineal crypts, anterior and posterior communion and other localization mark structures.

This is a key step in directional surgery: ventricular angiography!

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

Then, the anterior angle of the lateral ventricle was pierced through the skull bone, and pressure-inflating ventricular imaging or inject 10 ml of positive contrast agent.

This is a complex multidisciplinary combined surgery.

Chen Cang dared not be careless.

The hospital also attaches great importance to this.

This time, Wu Tongfu personally came to the operating room wearing a surgical gown.

Also coming were Hu Chuanbang of Neurosurgery and Zhao Furun of Neurology.

After they came in, they just saw the contrast agent being put down.

The director of the radiology department said: "Everyone dodge it."

Everyone gave in to the back of the screen.

Wu Tongfu looked at Chen Cang and couldn't help asking, "How confident 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 nodded: "Either succeed or fail!"

Wu Tongfu was speechless!

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

Your sister, how nervous I am? Are you and me humorous?

In fact, it cannot be blamed for Chen Cang. The operation has not started and the target positioning has not been determined. How can we talk about the success rate?

It would be great if the directional surgery was really that simple!

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

Zhao Furun nodded: "That's right, if Parkinson's surgery can have a success rate of 50%, Professor Chen might have a chance to attack Nobel!"

How many years has Parkinson bothered the nervous system?

Everyone was stuck outside this gate and couldn't move forward.

How easy is it?

Wu Tongfu was stunned and then realized!

He spoke in a tone: "Don't worry if you fail, come on!"

Here, after the filming of the director of the Radiology Department finished, the report was quickly released, very quickly and accurately!

"Professor Chen, the film is out!"

Chen Cang's eyes lit up immediately: "Now!"

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

After saying that, he couldn't wait to walk outside.

Wu Hui followed closely behind.

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

"This kid Chen Cang... is so hard!"

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

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

Comparing in two groups, the changes are really too big!

"Yes!" Hu Chuanbang nodded.

Wu Tongfu sighed for a long time.

The greater the honor, the more difficult it is!

Success often means giving.

"He has only been resting for a while, and he is now devoted to Parkinson's research. Alas..."
