There is no need to be too normal to be a doctor

When Chen Gong left, he held a lot of information in his hands.

Yang Guangye worked hard to find a lot of materials for this topic, and even found many of them from Xu Tong.

Obviously, as a mature biochemical theoretical knowledge, the tricarboxylic cycle has not found an entry point in clinical application, which is obviously a waste.

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

This way.

Chen Gong doesn't have enough time right now.

On the one hand, we need to dig deeper into the issue of the tricarboxyl cycle.

On the one hand, you need to learn how to perfect the lower cervical spine arch surgery.

On the one hand, I also need to record lecture videos and occasionally ask questions.

So now, although he is still a student, he is no better than those who are engaged in scientific research.

【Ding! Trigger task: Participate in the construction of the tricarboxylic cycle project. 】

[Task tip: You are ranked third in the research group and need to contribute at least 20% to the project. Current contribution: 7%. 】

[Task completion reward: blue treasure chest +1;]

[Warm reminder: As a medical student, taking on the third responsibility of the research team is obviously not something a normal person can do, right? 】

…

Chen Gong took one look at the system and immediately forked it.

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

Is this task something a normal person can do?

Chen Gong couldn't help but shook his head and stopped thinking about these things.

The task statement for the tricarboxylic cycle has not yet been released. Yang Guangye needs to complete a lot of work early, and time is not urgent.

Therefore, the top priority is to think about Director Qin’s topic.

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

Only Li Bo is in the laboratory at this time.

After seeing Chen Gong coming, he smiled and said, "Come here."

"Hello, Teacher Li." Chen Gong nodded. Seeing Li Bo operating a lower cervical vertebra mold, he couldn't help but ask: "Are you performing anterior AO locking plate and screw surgery? Do you need my help?" "

When Li Bo heard this, he immediately laughed: "Not bad, you actually saw it."

Chen Gong smiled and said: "It's okay, okay. I can see it after seeing it too much. The difference is actually very obvious."

Li Bo nodded: "Okay, come here and do me a favor."

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

"Anterior surgery has actually only been improved in recent years. Generally speaking, innovation in surgical techniques cannot be so fast."

"However, the lower cervical spine surgery we want to do is not for the majority of patients, but for those patients who have difficulty in articular process reduction, or who require tracheostomy or have tumors that limit surgery."

Chen Gong looked at Li Bo and couldn't help but ask: "Mr. Li, you know so much about orthopedic surgery. If you go to clinical practice and perform surgery, wouldn't it be too bad?"

Li Bo smiled when he heard this: "Theoretically, that's the case."

"However, when it comes to clinical practice, there are more things that need to be paid attention to. For example, at this time, I can do the simulation calmly because the person opposite me is a model, not a real person."

"Moreover, the conditions of clinical patients are complex and cannot be as simple as the model. They often have various diseases."

"So, there are some gaps in terms of mentality and understanding of clinical situations."

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

Li Bo is of medium height, with a short haircut. He usually wears a pair of gold-rimmed glasses, and his body always smells like clothes that have been washed and dried in the sun.

The way he speaks and acts gives people a very clean feeling, especially when he smiles, he looks like the big brother next door.

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

Soon, the two of them got involved in the experiment.

"Measure PH (pedicle height)."

"Okay, I'm going to put the screws in, and now I'm going to measure the PW (pedicle width)."

"Pay attention to the axis."

"Yes, help me hold this thread."

…

The simulated surgery proceeds slowly.

Chen Gong looked at Li Bo's surgery and felt that his anatomy knowledge was growing rapidly, and he also had some inspiration for surgical improvement? !

With a thought in his mind, 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 makes people very addicted.

The most critical step of the surgery is to fix the screws that fix the plate into the cortical bone at the posterior edge of the vertebral body.

Anterior AO locking plate and screw fixation sounds complicated.

In fact, to put it bluntly, it’s very simple!

It means that the cervical vertebrae are broken, the pressure is too great, squeezing or damaging the nerves, and the head cannot bear the pressure.

At this time, the damaged area needs to be rebuilt.

So, we found an opening in the front of the neck to find the damaged lower cervical vertebra, then put a steel plate with screws in, fixed it, and then inserted the screws into the lower vertebral body.

In fact, it's just like a chair. The back of the chair is loose. At this time, find a fixed gasket, then nail it in with a few nails and fix it.

The gasket is the steel plate, and the nails are screws.

The combination of this is called: "Anterior AO locking spacer nailing technique on the chair back!"

Well, what else would happen if people engaged in scientific research look down on those engaged in surgery?

Too rough.

What is the difference between this and a craftsman?

The difference is that when you fix it, the screw cannot damage the chair.

That's the problem!

Anterior AO locking steel plate has a total of five screws on the steel plate, four of which are 14 mm in length.

This length can ensure stability.

The last fixing screw is 18 mm.

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

Therefore, the four screws will not penetrate, but in order to maintain the stability of the plate and the cervical spine, the locking plate needs to have a locking one, which must be 18 mm in length.

Screws that penetrate the bone cortex on both sides of the vertebral body can achieve sufficient stability. For example, if you find a nail and nail it to a chair, it can be fixed, but... it is too long and damages the chair.

Therefore, this technology still has the risk of spinal cord injury!

The stability has improved, but the risk factor has also increased.

At the same time, if the patient has osteoporosis or a relatively high mobility of the cervical spine, the screws will change, causing a series of complications.

Chen Gong observed and observed, and suddenly understood why the thickness, length, and angle of the cervical spine should be tested.

turn out to be……

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

This is so much fun!

Thinking of this, the corners of Chen Gong's mouth raised. It seemed that he should read more books.

Soon, the experiment was completed.

Li Bo took a deep breath and quickly started testing, and the data was successfully recorded.

"Hey, it's not bad. It's a pity that Teacher Liu is not here, otherwise we can make a comparison."

When Chen Gong heard this, did he need posterior surgery?

After Li Bo finished speaking, he said to Chen Gong: "Xiao Chen, think about it carefully. If you want to complete the update of the technique, there are many things that need to be understood and observed."

"I'm going out here first."

"When Teacher Liu comes and performs posterior surgery, we can compare."

"Teacher Liu probably won't be here for a while."

Chen Gong heard this and hesitated: "I... I actually know the way out..."

But before he finished speaking, Li Bo left. Chen Gong hesitated and took out a model.

He has learned how to do posterior surgery during this time, why not give it a try?

Just do it!

Chen Gong did it without any hesitation.

Posterior surgery is called posterior spinous process wire fixation.

Well, let’s use a chair as an example.

Just use a wire to tie the spinous process from behind.

This vertebral body has special characteristics.

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

This is because the bone structure of the vertebral body in the front of the cervical spine is not as strong as the bone structure in the back. Therefore, the natural advantage of anterior plate fixation is not as stable as that of the posterior approach.

Sure enough, knowledge is needed to understand everything in the world, and foodies can be open-minded and write articles!

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

But Li Bo hadn't come back yet. Seeing that it was 12 noon, Chen Gong simply put the things on the table, got up and left.
