Chapter 436 The dead friend is not dead

If "Puze's latest medicine" is not very weighty, then "cell" is absolutely convincing.

As the magazine with the third highest impact factor in the world, the influence of "Cell" is definitely not as simple as it says.

To give a simple example, if some new knowledge is published in other journals, the first thing many people think of is is it true?Yes, the first feeling is doubt!
And if an article is published on "cell", most people's first feeling is: this should be true!
Because "cell" regularly publishes some new guidelines every year, and many people use these guidelines directly.

The whole reason is because of "cell", his name is more convincing than any other brand.

When "The Deceit of the Times" was released, people who were waiting and watching and skeptical seemed to have found the backbone. Even if they didn't say it, they had already admitted it in their hearts.

Is it true that cobalt chrome is a hoax of the times?
If true, the impact of this is simply too great.

In the world, there are tens of millions of people with cobalt-chromium alloy prosthesis in their bodies, which means that among every dozens of people in the United States, there may be one person with cobalt-chromium alloy in their bodies.

And these people are basically some older patients, what are the most elderly people?
Complications, all kinds of strange illnesses.

After all, it is normal for people to have some physical problems when they are old.

In normal times, everyone might think that this is a very normal thing. After all, people are old, their organs are failing, and it is normal to have a little ailment.

But at this time, "Cell" reported the harm of cobalt-chromium alloy and many complications.

This made everyone wonder whether the discomfort and complications of their parents and elders were related to the cobalt-chromium alloy in the body?
On November [-]st, on the streets of Detroit, USA, tens of thousands of citizens gathered in Central Park. They wore special clothes, held signs, and walked towards the Hankison Building.

This is the first time in the city of Detroit that there has been such a large-scale parade in the past 20 years.

The huge number of people and the grand scale shocked the passers-by!
At this time, on the top floor of the Hankison Building, Pierce looked at the dense crowd outside through the floor-to-ceiling windows, watching them all holding signs and wearing a special red armband around their arms. They just stood downstairs.

From a distance, you can see a few slogans:
"Hankison, please stand up and explain!"

"Where is the right to know?"

"Positive response to cobalt chromium alloy!"

………………

Seeing these brands, Pierce was very upset. He never thought that "cell" would publish such a journal during the stalemate, which was really not a wise choice for Fei Nuo.

However, upset is upset, Pierce did not feel scared.

Fenuo Group has grown up to now, and has experienced many devastating disasters, large and small!
Can this little thing scare them?
It is too underestimating the ability of a Fortune [-] company.

In Phoenix, Arizona, USA, the current chairman of Fenuo Group, Bukdi, came to the state government. As the largest taxpayer in Phoenix, Bukdi has a great say in this city.

It is conservatively estimated that the Pheno Group has solved the employment of nearly 3 people in Arizona, built the latest government building for the city, and established the most popular scholarship in the state university.

If something happens to the Fei Nuo Group, all of this will cease to exist.

Booker is confident enough that the Arizona state government, which has independent laws, will not let the Feynor Group do anything, even if there is, it is not now.

The US presidential election is coming soon. At this time, the friendship of a Fortune [-] company is something that everyone must strive for.

This is also the source of Bu Kedi's self-confidence.

At the same time, many senior executives within the Fei Nuo Group began to negotiate with many companies and companies, hoping to get help from each other.

After all, in the capitalist world, profit is the longest friend.

........................

........................

Bai Ye's opening report was postponed, and he voluntarily applied for the extension. After all, compared with the opening report, the most important thing at present is to solve the shortage of prostheses caused by the lack of cobalt-chromium alloy.

Many people in China are now waiting for the emergence of a new prosthesis to replace cobalt-chromium alloy, and millions of people are waiting for the prosthesis that can be used instead.

After the release of the Fei Nuo Group's sales ban, the impact was too great, and it was getting bigger and bigger every day.

No matter who wins, if there is no suitable prosthesis, the patient will be the one who suffers and is injured!

Bai Ye won, yes, cobalt-chromium alloy is a failed prosthetic material that is harmful to the human body, but so what?
Do you currently have a product that could replace cobalt chrome?

No!

This is the greatest confidence of the Fei Nuo Group. They have been studying orthopedic prostheses for many years, and the research on new materials has never stagnated, but there is still no material that can replace cobalt-chromium alloy.

The Fei Nuo Group believes that no matter what the outcome of this matter, they can get through it smoothly.

Is this what Bai Ye wants to see?

of course not!

Ever since he got orthopedic nails, Bai Ye invited Nana Xi to join the research institute, and the institute's material research has never stopped since then. What orthopedic nails bring is by no means as simple as a single nail.

That is a new type of material.

That material opened the door for South Africa's creek to study new materials.

Can this absorbable high-strength material replace cobalt-chromium alloy?
This problem is the most important problem to be solved by the research institute recently. For this reason, Bai Ye discussed and discussed with South Africa Creek and Moldo all day long.

Because this PLA absorbable nail is a substance that can be absorbed and decomposed by the human body, the final products are carbon dioxide and water.

However, the hardness and strength of this absorbable bone nail material cannot be compared with cobalt-chromium alloy at all.

indeed!

At this stage, there is still no substance that can replace the market position of cobalt-chromium alloy.

Is it possible to choose a titanium alloy with a slightly lower quality?

This is equivalent to several years of technology backward, just like the emergence of smart phones, people are still willing to use those antique phones?

So, how can we find a new type of substance that can replace cobalt-chromium alloy?
South Africa Creek can be said to be racking its brains these days, and has not gotten an effective solution.

How to do?
Three people were sitting in the office, each frowning, staring at the desktop, racking their brains to find a solution.

Bai Ye raised his head, and when he was staring at the ceiling in a daze, he suddenly saw a spot on the ceiling, which seemed to be the reason for the peeling off of the wall.

Immediately!

An idea appeared in Bai Ye's mind!
He hurriedly asked Nan Nanxi: "Old Nan, how long can the PLA absorbable bone nail material last in the body?"

South Africa Creek frowned: "This new PLA material is mainly used for fixation and can be used to make bone nails. Its strength can only be maintained for 3-6 years. Only within six years can its strength and elasticity be maintained at a certain level. In a good state, if the time is too long, it will be difficult to maintain his effect!"

"You don't want to use this material to make prostheses, do you? Lao Bai, this is not suitable. The prosthesis made of this kind of thing is even inferior to titanium alloy or stainless steel. This kind of thing... no ah!"

Bai Ye shook his head: "No, what I want to ask is, how long does it take for this new type of plA substance to be decomposed in the human body? How long can it maintain its reliability in this environment of the human body?"

South Africa Creek: "Under normal circumstances, this new type of PLA absorbable substance will actually take some time to be completely decomposed, about ten years! Within ten years... what do you mean?!"

Nan Nanxi suddenly widened his eyes in the middle of speaking, stared at Bai Ye in disbelief, then suddenly slapped the table and stood up: "Brother-in-law, you are simply a genius!"

"You mean... amazing... amazing! It's really amazing! Thanks to my brother-in-law, this situation is completely feasible!"

Bai Ye saw that Na Nanxi had already guessed his thoughts, so he also smiled. As expected of a master of materials, he had already guessed what he was going to do before he reminded him!
And Moldo looked at the two with a blank face, not knowing what to say.

"You two... Teacher, what are you talking about?"

South African Creek is impatient, unable to bear the excitement in his heart, he said directly: "Professor Moldo, what my brother-in-law means is that the PLA new absorbable material is a stable orthopedic fixation material, and it can be used as a bone nail clinically. , His stability and strength are quite good in all aspects, and the substance of cobalt-chromium alloy is not without any advantages.”

"However, we can combine the two to create a new breed. In this way, the two sides can make up for each other's shortcomings."

Bai Ye nodded: "Yes, Moldo, I have an idea, which is to make a material like a PLA coating on the surface of the cobalt-chromium alloy, so that we can give full play to the hardness and strength of the cobalt-chromium alloy. And other physical properties, and PLA absorbability and non-toxicity can be used to build a safe and reliable envelope to prevent abnormal ionization of cobalt-chromium alloy in the human body."

"The stability and existence of PLA absorbable materials can last for about ten years, while the service life of prostheses is generally about ten years, and they need to be replaced in ten years. Therefore, PLA materials are perfect for this decade. It worked perfectly!"

After listening to Bai Ye's explanation, Moore's eyes lighted up. This idea is really great!

But... why didn't I feel surprised?
He smiled slightly, this is Bai Ye, his seemingly omnipotent teacher!

Bai Ye looked at Nan Nanxi and asked, "Old Nan, what is the success rate of the product I just conceived?"

South African Creek excitedly picked up a piece of paper and a pen, wrote and drew on the paper, and even had some molecular equations. He said while writing: "Brother-in-law, you are amazing! When you said it just now, I already I began to think about its feasibility. If nothing unexpected, there should be no problem, because the plasticity of this PLA material is too strong. When we were studying this material, we had already discovered that this plasticity can be said It is very suitable for this new type of artificial prosthesis!"

No one would have imagined that the research on a new type of artificial prosthesis turned out to be a thought induced by a falling off wall.

After pondering for a while, the three of them immediately divided up the work and started further research.

....................................

....................................

These days, because of the matter of cobalt-chromium alloy, the whole industry is full of uproar. Even the American NBC TV station and many other media have begun to report on the matter of cobalt-chromium alloy.

After all, this matter involves too much and involves too much, and it is no longer a matter of the Fei Nuo Group.

Fei Nuo Group is rich and powerful, and their background is not comparable to that of ordinary companies.

But those small companies are different. They have no background. They originally thought that they would follow behind the Fei Nuo Group to eat meat and drink soup. Now even the Fei Nuo Group is a little trembling and cautious, so they have to let the surrounding The company began to find its own way out of the future.

Because, if something goes wrong with cobalt chromium alloy, it will definitely be those small companies that have problems.

It has been half a month since the supply of domestic cobalt-chromium alloys has been stopped. This half-month is not an optimistic thing for companies that are already in tight capital chains all the time.

During this tense period, the domestic health department issued a notice:

"Regarding the use of cobalt-chromium alloy prostheses, according to relevant research by the Chinese Academy of Sciences... cobalt-chromium alloys do have obvious side effects on... I hope patients, their families, and medical staff should be cautious when choosing artificial prostheses! "

Although this announcement did not prohibit the use of cobalt-chromium alloys, it did indeed illustrate the dangers of this cobalt-chromium alloy prosthesis!
This is an order announcement issued by the state, and its accuracy is beyond doubt. Patients who originally wanted to undergo joint replacement surgery all looked sideways.

How will this matter be resolved in the end?

At this time, Bai Ye had already sent Monica to contact these cobalt-chromium alloy production and R&D medical institutions in secret to prepare for the next step.

On November 11rd, on this day, the US Food and Drug Administration finally spoke!
This is the first time the FDA has issued a public statement after the cobalt-chromium alloy accident. As the safety review bureau of the United States and many countries in the world, their authority is too high.

"When cobalt-chromium alloys exposed a series of problems, our supervisory bureau immediately conducted various reviews on cobalt-chromium alloys on the market. After the review, we found that the quality of cobalt-chromium alloy prostheses on the market was uneven. Even security and reliability are difficult to unify!"

"This is a dereliction of duty in our work. Cobalt-chromium alloy is a new type of alloy material with high technical difficulty and high technological content. In the next time, we will strengthen the review of cobalt-chromium alloy. Cobalt-chromium alloy companies with hidden dangers will be dealt with strictly."

"FDA will set up a special committee for cobalt-chromium alloys to conduct public hearings on cobalt-chromium alloy products and conduct a comprehensive investigation of medical companies currently qualified for production and sales. The consultant of this committee is Mr. Pierce from Hankerson Company, He has extensive experience in cobalt chromium alloys….”

The announcement of this news immediately detonated the entire cobalt-chromium alloy circle!
A dead fellow is not a poor fellow?
Fei Nuo Group is going to push the pot!

The words of the U.S. Food and Drug Safety Administration are thought-provoking!
