When Chen Gong left, he held a lot of materials in his hand.

For this topic, Yang Guangye went to great lengths to find a lot of materials, and even many of them were found by Xu Tong.

Obviously, the tricarboxyl cycle is a mature biochemical theoretical knowledge, but in clinical application, it has not found an entry point, which is obviously a bit wasteful.

The purpose of applied research is to transform theory into application.

And so it goes.

Chen Gong's time is a little insufficient at the moment.

On the one hand, it is necessary to dig deep into the issue of the three-carboxyl cycle.

On the one hand, it is necessary to learn the perfection of the lower cervical vertebral arch technique.

On the one hand, it is also necessary to record lecture videos and occasionally give questions.

So now, although he is still a student, he is not much better than those who are engaged in scientific research.

【Ding! Trigger task: Participate in the construction of the three-carboxyl cycle project. 】

[Task Reminder: If you rank third in the research group, you need to undertake at least 20% of the project contribution, and the current contribution: 7%.] 】

【Quest Completion Reward: Blue Chest +1;】

[Reminder: If you are a medical student and assume the responsibility of the third part of the research group, it is obviously not something that a normal person can do, right?] 】

……

Chen Gong glanced at the system and forked it directly.

He has now discovered that it is not that he is abnormal, but that the system is abnormal.

Is this a task that a normal person can do?

Chen Gong couldn't help but shake his head, not thinking about these things anymore.

The task book of the three-carboxyl cycle has not yet come down, and Yang Guangye needs to complete more work in the early stage, and the time is not urgent.

Therefore, the top priority is to ponder this topic of Director Qin.

Thinking of this, Chen Gong glanced at the time and went directly to the laboratory.

Only Li Bo was in the lab at this time.

After seeing Chen Gong coming, he smiled: "Come here." ”

"Hello Mr. Li." Chen Gong nodded, and saw that Li Bo was operating on a lower cervical spine mold, and couldn't help but ask: "Are you performing anterior AO locking plate screw surgery?" Need my help? ”

When Li Bo heard this, he immediately laughed: "Yes, you can see it." ”

Chen Gong smiled: "It's okay, it's okay, I usually watch it a lot, and I can see it, the difference is actually obvious." ”

Li Bo nodded: "It's okay, come here, you can do me a favor." ”

Chen Gong nodded, changed his clothes, put on gloves and walked over.

"Anterior surgery has only been improved in recent years, and in general, the innovation of surgical procedures cannot be so fast."

"However, the lower cervical spine surgery we are going to do is not for the majority of patients, but for those who have difficulty in repositioning the articular process, or who require tracheostomy and have limited surgery for tumors."

Chen Gong looked at Li Bo and couldn't help but ask: "Teacher Li, you know so much about orthopedic surgery, if you go to clinical practice and do surgery, won't it be too bad?" ”

Li Bo smiled when he heard this: "Theoretically, this is the case. ”

"However, when it comes to the clinic, there are more things that need to be paid attention to, for example, at this time, I can calmly do simulations, because I am opposite a model, not a real person."

"And what about clinical patients, the situation is complex, it can't be as simple as a model, and it often carries various diseases."

"Therefore, there are some gaps in both the mentality and the grasp of the clinical situation."

"Of course, at the technical level of pure surgery, if it can be verified in the clinic for a period of time, there is no problem."

Li Bo is of medium height, with a small head, usually wearing a pair of gold-rimmed glasses, and there is always a smell of clothes being dried in the sun after washing.

Talking and doing things gives people a very clean feeling, especially when they laugh, especially like the big brother next door.

"However, I prefer experiments to clinical, and the psychological pressure is not very great."

Soon, the two were engaged in the experiment.

"Measure PH (pedicle height)."

"Okay, I'm going to put the screws, you measure the PW (pedicle width)"

"Pay attention to the axis."

"Yes, help me hold the line."

……

The simulated surgery was performed slowly.

Chen Gong looked at Li Bo's operation and felt that his anatomical knowledge was growing rapidly, and he also had some inspiration for surgical improvements.

His mind moved, and he suddenly had an idea, and activated the triple experience card.

Sure enough, with the help of the triple experience card, Chen Gong felt that his acuity, thinking activity, and learning ability soared rapidly.

This state of affairs is very addictive.

The most critical step of the surgery is to fix the screws that hold the plate in place in the cortex of the posterior edge of the vertebral body.

Anterior AO with locking plate screwfixation sounds complicated.

Actually, to put it bluntly, it's very simple!

It is that the cervical spine is broken, the pressure is too great, the nerve is crushed or damaged, and the head pressure cannot be borne at the same time.

At this point, the broken area needs to be rebuilt.

So, find an opening in the front of the neck, find the damaged lower cervical vertebrae, then put a steel plate with screws in it, fix it, and then insert the screws into the vertebral body below.

In fact, it is really the same as a chair, the back of the chair is loose, at this time, find a fixed spacer, and then use a few nails to drive it in, and fix it.

This gasket is the steel plate, and the nail is the screw.

This is called "Anterior AO with Locking Spacer Nail Technique for the Back of the Chair!" ”

Well, otherwise, people who engage in scientific research don't look down on those who engage in surgery?

It's too rough.

What's the difference between this and a craftsman?

The difference is that when you fix it, the screw can't damage the chair.

That's the problem!

The front road AO is locked with a steel plate with a total of five screws, four of which have a length of 14 mm.

Such a length can ensure stability.

The last fixing screw too, 18 mm.

And the average sagittal diameter of the delicate vertebral body of the human body is 17.3 mm!

Therefore, the four screws will not pierce, but in order to maintain the stability of the steel plate and the cervical spine, the locking steel plate needs to have a lock, 18 mm length.

Screws penetrate the bilateral cortex of the vertebral body to obtain sufficient stability, for example, if you find a nail and nail a chair, it can be fixed, but ...... But because it was too long, it damaged the chair.

Therefore, this technique still carries the risk of spinal cord injury!

Stability has increased, but so has the risk factor.

At the same time, if the patient has osteoporosis or a high degree of mobility in the cervical spine, then there will be changes in the screws, resulting in a series of complications.

Chen Gong observed, and suddenly understood why the thickness, length, and angle of the cervical vertebrae were tested.

Originally......

To study medicine, you also need to learn physics, mechanics, and biomechanics......

It's so much fun!

Thinking of this, the corners of Chen Gong's mouth rose, it seems that he should read more books.

Soon, the experiment was completed.

Li Bo took a deep breath and hurriedly started the test, and the data was successfully and completely recorded.

"Hey, it's okay, it's a pity that Mr. Liu didn't come, otherwise we can make a comparison."

When Chen Gong heard it, did he have posterior surgery?

After Li Bo finished speaking, he said to Chen Gong: "Xiao Chen, you think about it carefully, if you want to complete the update of the technique, you need to understand and observe a lot of things. ”

"I'll go out first."

"When Mr. Liu comes, he will have a posterior operation, and then he can make a comparison."

"Teacher Liu estimates that it will take a while to come over."

Chen Gong heard the sound and hesitated: "I...... I actually know a lot about the back road......"

It's just that before he finished speaking, Li Bo left on the front foot, and Chen Gong hesitated and took out a model.

Posterior surgery, he has learned it during this time, why don't you try it?

Just do it!

Chen Gong did not hesitate at all, and did what he said.

Posterior surgery is called posterior spinous wire fixation.

Well, let's use chairs as an example.

It is to tie the spinous process with a wire from behind.

This vertebral body has characteristics.

For example, when you eat a sheep scorpion, you will feel that the sheep scorpion has more meat in the front and less meat in the back, and the bones are still hard.

This is because the bone structure of the anterior vertebral body of the cervical spine is not as strong as the posterior bone structure, so the anterior steel plate is fixed, and the natural advantage is not as stable as that of the posterior.

Sure enough, the world is full of knowledge, and foodies are open-minded!

Chen Gong started the operation as soon as he spoke, and it was successfully completed in less than an hour.

But at this time, Li Bo had not come back yet, and seeing that it was 12 o'clock at noon, Chen Gong simply put his things on the table and got up to leave.
