The relevant breakthrough still comes from the intracellular membrane cultivation technology.

The best thing to do should be to use homogeneous tissue to fight rejection.

However, this requires the cells of the transplanted person to be extracted and cultured.

Although somewhat similar to the uterine membranes of the artificial uterine technique.

But it's much more complicated.

To this end, Shenlong conducted a lot of experiments.

Finally, the qualified biological tissue membrane was successfully completed.

However, this technique also needs to extract the biological tissue of the surgeon in advance and perform endocardial culture, and only when the endometrial culture is successful can the operation be performed. Although it is a little troublesome, it avoids the rejection reaction in the later stage.

Of course, Su Han is very satisfied with the current technology.

The next step is to conduct animal experiments.

Animal experiments also use a variety of animals.

However, they are also medium-sized and large-sized animals.

Because this success is more objective.

Of course, the volume of the heart is different for different animals.

The experiment also selects animals of similar size.

If you are performing surgery on cattle and horses, you should also choose an age with the same heart size as a human being.

The first batch of surgeries was performed by Su Han himself.

Because before the artificial heart enters the clinic, Su Han must have a very good understanding of all aspects of the operation.

First, the endocardial and vascular cultures are performed using the cells of the target animal.

First, 3D printing technology is used to print blood vessels and heart lining, and then the printed body is placed into artificial amniotic fluid, and the cells and tissues and blood of the implanted animals are placed at the same time.

The tissue and blood go through a series of complex processes to obtain the tissue fluid. The tissue fluid is then placed into a petri dish, and then the fine tissue is stimulated by an electric current, and the cell tissue finally attaches to the printed body.

The Petri dish is then placed into a special machine for growth.

until it looks like it needs surgery.

Then take the print out.

You can get the same blood vessels and the lining of the heart.

Finally, the blood vessels and endometrium are attached to the mechanical heart.

Then you can proceed with the surgery.

Su Han has successfully completed several pig heart transplants.

The postoperative observation effect is very good.

I didn't see any rejection at all.

Su Han then gave a heart transplant to a cow weighing 120 pounds and a horse weighing 120 pounds.

Cattle and horses that have had their hearts transplanted have recovered their health after surgery.

But athletic capacity is greatly reduced.

It seems that the heart designed for humans is not enough to meet the athletic needs of cattle and horses.

However, the transplanted pigs did not lose their ability to exercise.

It seems that the human heart and the pig heart are quite suitable.

Su Han then gave heart transplants to two more chimpanzees.

Of course, these surgeries were performed secretly.

This is because the use of chimpanzees for surgery is strictly restricted.

Advance application is required if necessary.

But Su Han didn't have that much time to apply.

Anyway, this kind of thing is not held accountable by the people.

As long as you don't say it yourself.

Who knows what experiments they have done.

Two chimpanzees that had been transplanted with artificial hearts recovered.

The body is in better shape than ever.

This will be followed by a period of observation.

in order to decide whether to apply to the state for clinical trials.

……

The year 2032 came.

……

Huaxia's economy continued to rise steadily.

Although it has slowed down slightly compared to the previous two years, there is only a growth of five percent.

But as the world's largest economy.

It's a great result to have that.

……

The robot dividends in various countries are almost digested.

Growth has also slowed.

The annual growth of the Mi Federation was only one percent.

Compared to the previous two years, it is simply a difference between heaven and earth.

……

Early.

The second phase of the in vitro pregnancy experiment officially began.

More than a hundred couples participated in the experiment.

These people have extracted the essence of life as requested.

The next thing is to wait for news.

……

The ITER unit has been commissioned and ramped up for more than a year.

It was decided to conduct a second open ignition experiment.

Experts from the participating countries also arrived at the scene.

I want to see how it looks after debugging.

With the formation of plasma in the cavity.

Ignition also begins.

Little by little, time passed.

Soon it was more than 200 meters per second.

It can be said that this achievement has reached one-third of the target target.

Naturally, the team in charge was very excited.

However, in the end, the reaction suddenly stopped at about two hundred and thirty seconds.

There is no way to be responsible, and the team can only simply debug and experiment again.

It's just that the second time it only lasted 200 meters and then stopped again.

The third ignition lasted one hundred and fifty seconds, and it was not even as good as the second.

Experts from various countries were also disappointed when they saw this.

Because the Dragon 1 can operate stably for almost a year, it will be stopped and very little time will be spent on overhaul and maintenance.

The best case scenario for the ITER device is only 230 seconds.

The two sides are simply not at the same level.

Is nuclear fusion really far away?

Fortunately, the ITER device lasted nearly 300 seconds during the fifth ignition.

This is already half of the target.

Although it is already very ideal.

But in the eyes of the vast majority of the countries participating in the project, it is simply scum.

In the end, ITER's Q value reached five.

Although the minimum preset value was reached.

However, it is still very different from the requirements of other countries.

Not to mention the Dragon One.

……

February.

Phase III clinical trials of artificial kidneys have officially begun.

The experiment will involve 400 patients with severe kidney disease.

Among them were a hundred foreigners.

These doctors under Su Han were already very proficient in related surgeries at this time.

Twenty or thirty related surgeries can be performed every day.

It took less than a month for all 400 patients to have their surgeries completed.

However, during this period, there was a patient who had a heart attack during the operation, and finally died after rescue failed.

made Su Han also a little depressed.

But he also knows that he is not an immortal either.

It is impossible to predict everything.

It can only be said that the man was unlucky.

……

A month later.

Almost all of the kidney transplant patients during the observation period were discharged from the hospital.

The third phase of the experiment is also considered to be the first phase, and it is officially over.

……

Longhan Technology immediately officially announced the matter.

The news is once again in the hot news around the world.

A total of 510 surgeries were performed.

Only one person died during this period.

The success rate of the surgery is surprisingly high.

More importantly, Longhan Technology also conducted an investigation report on the discharged patients in the first and second phases in the official announcement.

Almost all of them have returned to their normal lives.

Compared to the days of dialysis every day, it was like a new life.

At this time, almost the global media was reporting on the front page.

The great era of artificial kidneys has arrived.

The related news is naturally a few happy and a few sad.

The rejoicing are of course those who are in dire need of a kidney replacement.

First of all, they don't have to wait for the kidneys.
