At this time, the meeting scene was silent.

Everyone looked at Chen Gong in unison, wanting to see what good solutions he had to face these problems.

Because from beginning to end, no one saw a trace of panic or uneasiness in Chen Gong's eyes.

That's amazing!

You must know that the improvement of the technique, or the update and iteration of the theory, all need to overcome every difficulty step by step, basically step by step, step by step.

In this way, relying on everyone's brainstorming and the efforts of a group of people, results can be achieved.

That's why the research group needs so many people.

How old is Chen Gong's child?

Sophomore!

A sophomore, not to mention mastering such a wealth of theoretical knowledge, has also learned solid high-math complex variables and biomechanics across the line......

It's a monster, it's just not normal.

This is no longer a volume, this is breaking the rules of the industry......

Everyone smiled bitterly in their hearts, but they also hoped that Chen Gong could really achieve something.

At this time, it is in the eyes of everyone.

Chen Gong picked up the chalk and began to write, this time, he drew and explained.

"Regarding everyone's problems, I will analyze them in five steps!"

"First of all, the first one, structural feasibility analysis, is the structural feasibility that Mr. Li Bo said."

"It is well known that the width of the pedicle of the cervical vertebrae is less than the height, and the pedicle section is approximately oval.

The width of the pedicle can accept screws with a diameter of 3-4.5mm.

So, based on this characteristic, I designed a complete set of screws for the pedicle.

The diameters are 3.0mm, 3.5mm, 4.0mm, and 4.5mm.

In this way, the diameter of the screw is less than the width of the pedicle of the corresponding segment PW and slightly larger than the ......width of the cancellous bone.

"However, traditional screws are obviously not usable, and when I designed the screws, I referred to some literature and techniques to design a small angle to facilitate bending, and in this way, it can conform to biomechanical ......."

While speaking, Chen Gong directly drew a complete set of screws and four kinds of screws around the pedicle.

After this scene appeared, everyone present was completely stunned!

Boy!

You're really well prepared?!

Even the matching screw specifications are ready, and the stability and various properties are calculated from a theoretical point of view?

Is it really appropriate to say that you are studying medicine?

Qin Xuehai also widened his eyes and was speechless for a long time.

What kind of monster is this?

To be honest, Qin Xuehai has been the project leader for so many years, and he has never fought such a rich battle!

You've even designed a patent for a screw.

Moreover, this degree of ingenuity, although not shocking, is obviously very suitable for surgery, and the curvature of this screw is obviously specially designed for surgery.

He, Qin Xuehai, has done so many surgeries, can't he see the beauty of this ingenious curvature?!

This is a bit of a shock.

Absolutely stunning!

Isn't the next step to apply for a patent?

Wait a minute!

Qin Xuehai suddenly realized something, and his face suddenly changed.

That's right!

This thing has to be patented.

This Xiao Chen must not have noticed......

And Chen Gong's next sentence made everyone dumbfounded: "This screw, I am already preparing to apply for relevant patents, and there are some specific details, so I will not show it to you." ”

As soon as these words came out, the scene was in an uproar!

Patent?!

Qin Xuehai's eyes widened, this kid is really not an ordinary person!

Did he really think of it all?

Even patents are in the pipeline?

However, Qin Xuehai still wrote a "patent" on paper, he knew that Chen Gong applied for a patent in three or two years, at least one year to start.

And this thing, he has to help Xiao Chen do it as soon as possible.

However, is this kid really that confident?

Does he believe that what he has designed works?

And Chen Gong went on to say:

"The second point is the depth of the screw!"

"According to the full length of the C3~C7 pedicle axis La and the length of the articular pedicle Lb nail depth of 25mm, the most suitable screw head end can reach the first third of the vertebral body, and the safety factor is the highest!"

"Therefore, this problem also happens to solve the safety problem that Director Qin is worried about."

"However, in order to solve the problem of surgery, the most important part needs to be solved, which is the problem of positioning the coordinates of the nail entry point."

"This is a clinical question that Director Li just raised."

"In this regard, I haven't done much in-depth research, mainly because I don't know much about clinical practice, so I can only roughly say what I think."

"My plan is to select the positioning point, or to go through mechanical analysis, statistical processing, and accurate measurements."

"First of all, the X-ray machine was used to take upper and lower axial images of the cervical vertebrae specimens, and the left and right 45° oblique films were used to measure 7 indicators, including YE, PSH, PSW, ......."

The radial value measured by the X-ray is then corrected by the magnification factor of the camera. The mean and standard deviation of each index were calculated, ANOVA was used for statistical comparison, and after determining the significance of ANOVA, multiple comparisons between groups were made by q-test......"

"In this way, you can get a specific positioning method!"

Below, everyone listened to Chen Gong's train of thought and couldn't help but fall into contemplation.

They may not know much about the previous stuff.

But when it comes to professional knowledge, everyone is absolutely no problem.

By the time Chen Gong spoke, the following had already begun to fall into discussion.

Qin Xuehai pulled Li Jinhuan and gestured frantically to something in the air, his eyes were full of brilliance.

"Okay, these indicators can be fully covered!"

"Indeed, this feasibility is good, if the point can be accurately determined, the difficulty of the operation will indeed be reduced!"

"yes, yes, this kid has a few brushes!"

"Tsk, Director Qin, where did you find this genius? I don't think people are worse than those experts. ”

"Okay, let's not talk about this now, let's see if the operation is feasible?"

"Yes, yes!"

……

The rest of the crowd is also discussing.

At this time, Chen Gong suddenly said: "Director Qin, Director Li, you are both clinical experts. ”

"I have a few thoughts on specific surgeries."

"First of all, the incision, I think it is possible to take a posterior median incision, and you only need to peel off the muscles on both sides of the spinous process to reach the outer edge of the articular process."

Subsequently, the nail insertion point was removed with a micro electric grinding drill, the bone cortex was determined, and the pedicle was drilled into the pedicle with a drill under the supervision of the "C" arm X-ray machine. ”

"Because in this case, we can look directly at the drill hole, which guarantees a safety factor."

"As for the specific details of the operation, I think you two have more say!"

After Chen Gong finished speaking, Li Jinhuan directly began to applaud excitedly:

"Good!"

"Exceptional!"

"The posterior median incision is a perfect fit for this procedure, and most importantly, the posterior median incision can significantly improve the safety of the procedure."

"You've got that in place!"

"Xiao Chen, have you ever been to the clinic and followed the operation?"

"I see you seem to have a great understanding of surgery!"

Chen Gong smiled awkwardly and shook his head: "I'm sorry, Director Li, I'm just talking on paper." ”

"I haven't done clinical surgery myself, but I've done simulated surgery and watched a lot of surgery videos."

"That's why I came up with some ideas of my own."

"But what is the specific implementation and comprehensive analysis of the safety factor, I am still in the theoretical stage!"

"So, I can't decide the specific technique."

"I can only provide a little bit of my current thinking."

"Thank you."

After finishing speaking, Chen Gong bowed to everyone.

And in the audience, the applause was boiling and lasted for a long time.

No one spoke.

But applause is everything.

Everyone doesn't know what kind of words to use, or what kind of praise language to praise Chen Gong.

Because this kind of word is too barren.

And Chen Gong's talent is too amazing.

Li Bo and Liu Yueqing watched Chen Gong come step by step, if they hadn't seen it with their own eyes, they wouldn't have felt so shocked.

How long has it been?

In less than a month, they have witnessed Chen Gong's growth in many aspects.

Maybe his skills are not so comprehensive and perfect, but in terms of this topic alone, it can be said that everyone here has done better than Chen Gong?

He is alone, from surgical improvement, to theoretical analysis, from mechanical discussion, to screw design, to surgical safety factor evaluation......

Wait a minute!

After this set of processes, Chen Gong participated in almost every aspect of the project.

If someone has asked before, how long does it take to participate in a project, understand and participate in the project process, and make a certain contribution?

Li Bo would definitely say that it will take at least a few years.

But!

Now, he has to say that he has seen a miracle, a project, a multi-link participation in the whole process, and made outstanding contributions, he only took less than a month.

Moreover, he was just a student, a sophomore at the age of 20.

How amazing and unbelievable is this?

In contrast, Liu Yueqing's eyes were smiling as if she was looking at her younger brother.
