The main core of stereotactic surgery is the need to use an orienteer.
The difficulty of Parkinson''s surgery is also here.
Precise positioning is needed to find surgical targets for stimulation or other operations with the help of orientation.
Chen Cang actually considered whether to use local anesthesia at the beginning.
However, after repeated, a small amount of general anesthesia was selected.
Then use local anesthesia to maintain!
After all, such an operation needs to observe the patient''s condition.
In addition, during the operation, especially the target manipulation, the chief surgeon and the patient need to work together.
And we need to constantly observe the patient''s situation to judge the operation.
Intracranial surgery under local anesthesia.
It''s challenging to think about it!
But
The reality is so cruel!
Therefore, such an operation with accurate grasp of anesthesia is still very difficult!
Even Chen Cang is still a little nervous about this operation!
After all, risk is always around.
If you put it in ancient times, you must give master Hua Tuo three incense sticks before the operation, and then start!
Chen Cang said to Wu Hui, "come on?"
Wu Hui nodded, eager to try.
Chen Cang appreciates Wu Hui''s point that he never counsels in what he should do.
Dare to make a difference!
How can you be a success?
Wu Hui is basically playing Orienteering except sleeping these two days.
I have to say that after half a year''s separation from my wife, there is a lot more time.
There''s no need to worry about those troubles.
The only difference is that I need to take custody as soon as possible!
He is eager to succeed!
Hope to be a superhero in children''s hearts.
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 middle line of the head was aligned with the central hole before and after the frame, that is, the middle line of the instrument.
Orienteer is a great invention of Neurosurgery!
There is no doubt about it.
After Wu Hui''s precise operation, the head is located in the center of the frame in the front and rear direction of the head.
In fact, the installation of extracranial orientation instrument seems to have no technical content, but in order to eliminate the positioning error as much as possible, it is still very particular!
At the same time, avoid tilting back, forward or rotating the frame.
After studying these days, Wu Hui has mastered it very well!
Chen Cang nodded: "very good, perfect!"
Wu Hui quietly gave way to his position.
Chen Cang started his own operation at this time.
He received the scalpel and made a 4cm long longitudinal incision 2.5cm next to the midline of the operation side before the coronal suture.
Then, the skull was drilled in the center of the incision, the dura was cut in a cross shape, and then electrocoagulation was performed on the cortical surface for ventricular puncture and target puncture.
One of the more troublesome aspects of neurosurgery and orthopedic surgery is the need to take films often in the middle of the operation.
That these orthopedic doctors eat a lot of rays!
After all, surgery can''t wear lead clothes. After all, how tired is it to wear that thing after standing for such a long time?
And covered in sweat!
After Chen Cang finished these operations, he must display the positioning marker structures such as the third ventricle, interventricular foramen, aqueduct, pineal recess and anterior and posterior commissure through ventriculography.
This is a key step in directional surgery: ventriculography!
At this time, the director of Radiology personally came over and nodded to Chen Cang.
Then, puncture the anterior horn of lateral ventricle through skull drilling, perform pressure inflation ventriculography or inject 10ml of positive contrast medium.
This is a complex multidisciplinary operation.
Chen Cang dare not be careless.
The hospital also attaches great importance to this.
Wu Tongfu personally came to the operating room wearing surgical clothes this time.
Hu Chuanbang of neurosurgery and Zhao Furun of Neurology came with him.
When they came in, they just saw the contrast medium playing down.
The director of Radiology said, "everyone dodge."
The crowd retreated behind the screen.
Wu Tongfu looked at Chen Cang and couldn''t help asking, "how sure are you?"
Chen Cang looked at the nervous president Wu and thought, "half."
Wu Tongfu breathed a sigh of relief: "it''s OK! Half is quite tall!"
Chen Cang said, "either succeed or fail!"
Wu Tongfu was speechless!
I want to swing a knife and draw a capital "Z" on Chen Cang.
Your sister, what am I nervous about? Are you humorous with me?
In fact, Chen Cang can''t be blamed. The operation didn''t start and the target positioning was not determined. What about the success rate?
If only directional surgery were so simple!
But... Hu Chuanbang couldn''t help saying, "Dean Wu, this is... Parkinson''s surgery!"
Zhao Furun nodded: "yes, if Parkinson''s surgery can have a 50% success rate when, Professor Chen may have a chance to impact the Nobel prize!"
How many years has Parkinson''s troubled the nervous system?
Everyone is stuck outside this gate.
How can it be that simple?
Wu Tongfu was stunned, and then he reacted!
He talked: "don''t worry about failure, come on!"
Here, after the radiology director took the film, he gave a report very quickly and accurately!
"Professor Chen, the film is out!"
Chen Cang''s eyes lit up: "right away!"
Then he glanced at Wu Tongfu and others: "I''ll go to surgery first!"
Then he couldn''t wait to go outside.
Wu Hui followed.
While Wu Tongfu looked at Chen Cang''s back and suddenly became silent:
"Chen Cang, this child... Too hard!"
This is what Wu Tongfu rarely calls Chen Cang a child.
When the boy came to find himself, it was a year ago.
Compared with two by two, the change is 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.
"How long has he been resting? In the twinkling of an eye, he has invested in the research of Parkinson''s disease. Hey..."
"I think I''m really too comfortable compared with this boy!"
Wu Tongfu could not help sighing.
The other two faces a red face. Why do they suddenly feel that Wu Tongfu is talking about himself.
Yes, they turned around and found that President Wu was staring at them.
Looking at the intracranial film, Chen Cang couldn''t help praising: "very good!"
We want to determine the landmark positions of the intraventricular foramen, aqueduct, pineal recess, etc.
You have to use the film.
If you want to determine how to perform intracranial surgery and find the key target location, you need to combine the orienteer and film, and then start calculation!
And it''s a precise calculation!
The target was the ventrolateral thalamic nucleus.
Because it has a significant effect on tremor and stiffness.
The medial part of globus pallidus has a significant effect on stiffness and motor retardation caused by Parkinson''s disease, but it is not so good for tremor.
However, the ventrolateral thalamic nucleus is more difficult to locate than the medial thalamic nucleus.
How to locate?
It is particularly important!
Chen Cang had to lament the backwardness of the instrument. If MRI + pet + digital analysis technology can be used, it can accurately locate and guide the operation.
Even through high-resolution MRI and thin-layer scanning, the images of deep brain structure in basal ganglia can be clearly displayed, which provides conditions for direct and accurate positioning of targets.
But on this condition, what kind of bike do we want?
Chen Cang can only use the most primitive technology for this operation.
If it succeeds, it will be a miracle.
