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

Chapter 73 Patent!

At this time, everyone in the meeting fell silent.

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

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

This is amazing!
You must know that improving surgical techniques or updating and iterating theory requires overcoming every difficulty step by step. Basically, every step is a hurdle, and every step is a difficulty.

In this way, only through the collective efforts of everyone and the efforts of a group of people can we achieve results.

This is why the research team needs so many people.

How old is Chen Gong?
Sophomore!

A sophomore student, not only has mastered such a wealth of theoretical knowledge, but also learned solid advanced complex variables and biomechanics across fields...

It's truly a monster, absolutely abnormal.

This is no longer cheating, this is breaking industry rules...

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

At this time, he was in everyone's attention.

Chen Gong picked up the chalk and started writing. This time, he explained it while drawing.

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

"First of all, the first one is structural feasibility analysis, which is what Teacher Li Bo calls structural feasibility."

“It is well known that the width of the cervical pedicle is smaller than its height, and the cross-section of the pedicle is approximately oval.

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

Therefore, based on this characteristic, I designed a complete set of screws suitable for pedicles.

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

In this way, the diameter of the screw is smaller than the width PW of the vertebral pedicle of the corresponding segment and slightly larger than the width of the cancellous bone PSW. The thread can cut into the cortical bone to maximize the pullout resistance and bending resistance..."

"However, traditional screws obviously cannot be used. When designing the screws, I referred to some literature and techniques and designed a small angle to facilitate bending, and in this way, it can comply with biomechanics..."

While talking, Chen Gong drew a complete set of screw entry diagrams and four types of screws directly around the pedicle.

After this scene appeared, everyone present was completely shocked!
Good guy!
Are you really prepared enough? !

Even the matching screw specifications are ready, and the stability and various performances have been calculated from a theoretical perspective?

You said you are studying medicine. Is this really appropriate?

Qin Xuehai also stared wide-eyed and was speechless for a long time.

What kind of monster is this?
To be honest, Qin Xuehai has never fought such a rich battle after being the project leader for so many years!

Even the screw patent has been designed.

Moreover, although this degree of ingenuity cannot be called shocking, it is obviously very suitable for surgery. The curvature of this screw is obviously specially designed for surgery.

Qin Xuehai has undergone so many surgeries, how can he not see the beauty of this ingenious curvature? !

This is a bit shocking.

Absolutely!
Isn’t the next step just to apply for a patent?
and many more!

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

Yup!

This thing needs to be patented.

This Xiao Chen must have not noticed...

Chen Gong's next words made everyone dumbfounded: "I am already preparing to apply for a related patent for this screw. There are some specific details, so I won't show them to you."

As soon as these words came out, there was an uproar at the scene!
apply for patent? !
Qin Xuehai also widened his eyes. This boy is really not an ordinary person!
Has he really thought about all this?

Are you even preparing a patent?
However, Qin Xuehai still wrote a "patent" on the paper. He knew that it would take at least one year for Chen Gong to apply for a patent, not three or two years.

As for this thing, he had to help Xiao Chen make it as soon as possible.

However, is this kid really that confident?

Does he believe that what he designed is feasible?

Chen Gong then said:

“The second point is how deep the screw goes in!”

“Based on the total length La of the C3-C7 pedicle axis and the length Lb of the articular process pedicle, the most suitable screw insertion depth is 25mm, which can reach the first third of the vertebral body, with the highest safety factor!”

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

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

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

"In this regard, I haven't done too much in-depth research, mainly because I don't know much about clinical practice, so I can only give a rough summary of my thoughts."

"My plan is to select the anchor points, which still needs to be carried out through mechanical analysis, statistical processing, and precise measurement."

"First, use an X-ray machine to take upper and lower axial films and left and right 45° oblique films of the cervical spine specimen to measure 7 indicators, including YE, PSH, PSW..."

"Then, the diameter value measured by the X-ray film is corrected by multiplying it by the magnification factor of the radiograph. Calculate the mean and standard deviation of each indicator, and use ANOVA for statistical comparison. After determining the significance of the variance analysis, use the q test There is no way to do multiple comparisons between groups..."

"In this way, we can get the specific positioning method!" Below, everyone listened to Chen Gong's thoughts and couldn't help but fall into deep thought.

They may not know much about those things before.

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

By the time Chen Gong spoke, the discussion below had already begun.

Qin Xuehai pulled Li Jinhuan and gestured wildly in the air, his eyes full of brilliance.

"Okay, these indicators can completely achieve full coverage!"

"Indeed, this is feasible. If the point can be accurately determined, the difficulty of the operation will indeed be reduced!"

"Yeah, it can be done, this guy has a few brushes!"

"Tsk tsk, Director Qin, where did you find this genius? I think he is no worse than those experts."

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

"Yep!"

……

Everyone below is also discussing.

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

"I have a few ideas about specific surgeries."

"The first is the incision. I think a posterior midline incision can be used, and only the muscles on both sides of the spinous process need to be peeled off to reach the outer edge of the articular process."

"Then use a micro-electric drill to remove the bone cortex at the nail entry point to determine the direction of the nail entry, and use a drill to drill into the vertebral pedicle under the supervision of a "C" arm X-ray machine."

"Because in this case, we can look directly into the borehole and ensure safety."

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

After Chen Gong finished speaking, Li Jinhuan started to applaud excitedly:
"it is good!"

"Excellent!"

“The posterior median incision is perfectly suited for this procedure and, most importantly, significantly improves surgical safety through the posterior median incision.”

"You have thought this through very well!"

"Xiao Chen, have you been to a clinic or had any surgery?"

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

Chen Gong smiled awkwardly and shook his head: "Sorry, Director Li, these are just words on paper."

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

“That’s why I came up with some of my own ideas.”

"But as for the specific implementation and comprehensive analysis of the safety factor, I'm still stuck in the theoretical stage!"

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

"I can only provide some of the ideas I currently have."

"thank you all."

After finishing speaking, Chen Gong bowed to everyone.

The audience suddenly burst into applause that lasted for a long time.

No one speaks.

But applause means everything.

Everyone doesn't know what words or words of praise should be used to praise Chen Gong.

Because such words are too barren.

And Chen Gong's talent is too amazing.

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

How long has it been?

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

Maybe his technology is not so comprehensive and perfect, but when it comes to this subject alone, it can be said that of all the people here, who can do it better than Chen Gong?
He alone goes from surgical improvement to theoretical analysis, from mechanical discussion to screw design to surgical safety assessment...

and many more!

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

If someone 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 would take at least a few years.

but!

Now, he had to say that he had seen a miracle. It took him less than a month to participate in the entire process of a project and make outstanding contributions.

Moreover, he is just a student, a 20-year-old sophomore.

How amazing and incredible is this?

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