"Ha? Professor Hoffman? The people from their team come to the hospital every now and then. They have helped us a lot during this period."

Speaking of Hoffman, Guan Zhenhai's tone was full of respect.

Because he knew that this foreigner had a very extraordinary background and was sent overseas, it was very likely related to the scientific research team behind Xiao Feng.

And the most important thing is that their medical skills are really awesome, and they have become famous in Sunshine Hospital for a long time.

For example, they have recently received several patients with severe burns and scalds, and even they feel it is difficult to deal with, but in the end they rescued the person at Hoffman's suggestion.

For example, two of the patients were firefighters. During the firefighting process, they were not only severely burned, but also blown down from the upper floor by airflow due to the explosion.

It caused multiple fractures and serious falls.

Even if this complex comprehensive injury is sent to the best hospital in China, it will definitely be helpless.

In the end, the fire department's superior decided to send him to Sunshine Hospital and take a risk.

When the person was sent, Guan Zhenhai was also shocked to be honest.

Although he is mainly engaged in burn and scalds, he has the burn and scalds ointment provided by the ninth laboratory and artificial skin.

Treating burns is an easy task for them.

However, the situation of these two patients is complicated. They not only have severe burns, but also have multiple fractures all over their bodies.

Originally, the most feared thing for patients with burns is infection.

But these two patients still have to undergo surgery first, remove the broken bones in their bodies and correct the bones.

Otherwise, even if the person is rescued, he will eventually be disabled.

If it were the past, they would definitely take the minority of the two powers.

It is definitely necessary to save the patient's life first. As for the disability, there is nothing we can do about it.

But Dr. Hoffman was in the hospital that day, so after seeing the situation, he made a bold suggestion.

He will take out the patient's broken bones and complete the bone replacement.

The military doctor from the 520 Hospital was confused when he heard this. Who is this? He actually spoke such a big tone?

Fortunately, Guan Zhenhai and the others knew Dr. Hoffman's level, so they talked to the military doctors.

Finally, after communicating with the patient's family, everyone decided to fight.

Then Dr. Hoffman took action, and he first took out the patient's broken bones.

If an ordinary orthopedic doctor faces such a problem, he must try to splice the broken bones as much as possible.

Only take it out if you don’t spell it out, then fix the spelled bones with steel nails, and finally let the bones grow by themselves.

But during this process, multiple infections will definitely occur, after all, the surgery is open-ended.

Moreover, steel nails must be implanted in the patient's body. Friction between these steel products and human muscles will definitely cause rejection reactions in the human body, so inflammation is inevitable.

What patients with burns and scalds are most afraid of is inflammation outbreaks.

So this is also a headache for many doctors.

But for Dr. Hoffman, it is not a problem at all.

He took out all the patient's tibia that was watered, then took out a replacement bone and replaced it directly.

This operation was stunned by Guan Zhenhai and the doctors sent by the military.

If you talk about bone replacement surgery, they have seen a lot of them before.

But most of them are bone replacements like the ankle, knee, and hip joints.

After all, it is not the main bone. These joint bones do not contain bone marrow and will not participate in the human immune and hematopoietic functions. Therefore, it doesn’t matter if these joint replacements and metal products are used.

But who have you ever seen a key big bone like the tibia and femur that is replaced?

It’s not that humans cannot produce substitutes for metal products of the same specifications, but because these bones in the human body not only play a role in supporting the weight of the human body and maintaining balance in the human body.

The most important thing is that the internal structure of these large bones has very small honeycomb-shaped holes.

And these holes are one of the most critical tissues that live in the human body, bone marrow!

The effect of bone marrow is too great. On the one hand, it is to convey nutrition to the bones and ensure the health of the bones.

On the other hand, he also has to participate in the human immune function to produce white blood cells, and he also has another very important function, that is, hematopoiesis.

So you can see that orthopedic doctors often replace complex bone structures such as knee, ankle, and hip joints for patients.

But it is rare to see doctors replace large bones such as tibia, fibula, and femur for patients.

Although such leg bones seem to be very simple in structure and are both long and straight, such bones are very important to the human body and cannot be replaced by metal products.

There have been countless scientific researchers who have tried to use 3D technology to print such bones for replacement, but few have been successful.

It is because there are very fine honeycomb-like holes inside these bones, which serve as a living space for bone marrow.

At present, artificial bones cannot reach that density at all.

Why did Hoffman marvel at the fact that the corals brought back from another world by Xiao Feng can perfectly fit the human body?

It is because the holes inside the coral are exactly the same as the holes in the bone joints in the main trunk parts of the human body.

Moreover, the main components of these corals are calcium, and the similarity to the main components of bones in the human body is 99% taller.

Moreover, after transplanting into the human body, there was no repulsion at all.

This is the most ideal human bone graft!

So Hoffman developed a crazy obsession with the materials.

In recent times, he has been mainly studying the reliability of these materials and how to use them on the human body.

The emergencies encountered in Sunshine Hospital this time provided him with a good opportunity to experiment.

Anyway, the firefighter has already said that he should treat the dead horse as a living horse and try his best, so he simply let it go.

His drastic actions shocked the orthopedic doctors who came from 520 Hospital.

You know, in the past, they must have been careful when they had such surgery.

Keep every bone of the injured person as much as possible and splice it into some.

But this doctor actually removed all the bones of the patient.

Then I changed into a new replacement.

Although Guan Zhenhai had explained to them before, this is an orthopedic expert they have found from overseas.

But they were still a little confused. After all, they had never heard of the reputation of this expert.

And this is this doctor. Are you too simple and crude?

Even if we can't understand the bone replacement in your hand, your replacement method is too sloppy, right?

You should know that when we used to do various bone and joint replacements, we would take out the bone and take measurements.

Then make continuous adjustments on the replacement product, adjust the size and shape of the replacement product to achieve the best adaptation result.

Then the replacement substance is installed, so as to ensure that the replacement substance is formed in the patient's bones and form a perfect fit.

It will not cause unexpected pain to the patient in the later stage because the size and shape are incomplete, because it is not perfect in harmony.

This is like installing a ceramic crown.

When the doctor puts the ceramic crown on you, you will make it feel like you bite yourself.

Because even this tooth crown was made after collecting the model from your mouth, even though this tooth crown is 99.5% similar to your original tooth.

But there are still some differences, so what the doctor needs to do at this time is fine-tuning.

He will use an electric drill to polish the crown based on your feedback on which point of the bite is uncomfortable.

Until you bite, you won't be in a uncomfortable position.

Orthopedic doctors will make such fine adjustments before installing the replacements on the patient.

However, because the patients were in a coma at this time, they could not communicate with the patients.

Even if they can communicate with the patient, the patient has no way to exert force because the injury has been opened, and it is completely impossible to feel the difference between this replacement and his own bones.

So at this time, it all depends on the doctor's experience.

Because if he does not make fine adjustments at this time, then this replacement is placed on the patient.

The horse has an error of a few centimeters, but when the patient recovers and can go to the ground, he will feel uncomfortable due to the force problem.

Moreover, this discomfort will cause muscle lesions and inflammation over time.

It may even cause lesions on the bones, so in order to avoid such problems.

When an orthopedic doctor replaces the patient's joints, he must polish the knee joints and ankle joints as much as possible before installation.

As much as possible, after installing the patient, it will not be imperfectly combined with the patient's original bones, and eventually bring other pain to the patient.

So now when they saw that Dr. Hoffmann did not make any fine-tuning of the replacement object and put it directly into the patient's body, they were all shocked.

There are even a few doctors who are more excited and think that he is just a quack doctor and doing so is completely careless about human life.

But in the end, with Guan Zhenhai's dissuasion, the doctors endured and did not rush into the operating room.

Only after Hoffman finished the operation did they gathered up to find Hoffman to explain.

Hoffman was not surprised by the curiosity of these doctors.

What he took out was a 3D perspective view of the perspective imaging equipment in the self-service physical examination center and photographed the patients.
