Hearing Xu You's words, Gong Rui was also surprised.

"Professor Xu, normally, after we have prepared a new type of artificial heart, we need to conduct in vitro testing first. According to the performance of the test, we will optimize the entire artificial heart to ensure that it can complete the functions of a biological heart .”

Gong Rui thought that Xu You didn't know the normal development process of the artificial heart, so he quickly explained to Xu You.

Because the artificial heart is a very precise structure, it is impossible to design it successfully at once, and it must be tested many times in the middle.

If the biological testing work is carried out directly after the design and preparation are completed, the result will almost certainly be that the transplanted animal will die directly.

The death of a pig is naturally not a big deal for humans.

However, during the operation, a lot of manpower and material costs will be consumed.

A surgical experiment that is bound to fail is not so meaningful, but will delay the normal progress.

"Professor Gong, I can guarantee that the artificial heart I designed can pass these in vitro tests. The time is very tight now, we can't waste any more time."

Waste a few days here, a few days there, and soon a month will be up.

At that time, if the new artificial heart is not ready, then Wang Xiangwu can only implant the old-fashioned artificial heart that is not very powerful.

Even if the operation is successful, it will be difficult for Wang Xiangwu to live a normal life like ordinary people.

After hesitating for a while, Gong Rui nodded heavily.

"Okay, Professor Xu, proceed according to your plan. Let's hurry up and produce your new artificial heart, and then start the artificial heart implantation experiment in animals immediately."

"Thank you Professor Gong for your trust." Xu You said politely.

Gong Rui waved his hand quickly when he heard the words: "Professor Xu, what you said is wrong. This is not your job in the first place. We are all very touched that you can help. This is not only for Professor Wang personally, but also for the whole contributions made by the medical community."

Under Gong Rui's arrangement, the new type of artificial heart designed by Xu You soon entered the preparation work.

3D printing technology is very practical for the preparation of artificial hearts, high-end customized products manufactured on a small scale.

With Xu You's complete design, the preparation of the artificial heart went very smoothly.

After several days of observation in the hospital, Xu You did not show any new symptoms and was allowed to leave the hospital.

Xu You waited anxiously for the news that the preparation of the new artificial heart had been completed.

Finally, on the fifteenth day.

Preparation of the first new artificial heart has been completed.

Gong Rui's experimental group is also preparing to conduct implantation experiments of a new type of artificial heart on animals.

As the designer of this heart, Xu You also came to the experiment site to observe the operation.

The experimental creature this time is a pig.

Because the heart structure of pigs is very similar to that of humans, experiments on pigs are usually carried out before clinical trials of artificial hearts.

There is even a case of directly transplanting a pig's heart into a human body.

The selected experimental pig is considered a very lucky pig.

Out of consideration for the purpose of the experiment, this experiment did not select a healthy pig, but a pig that itself had symptoms of heart failure.

In this way, the performance of this new artificial heart can be better evaluated, and it is not easy to cause resistance from pig lovers.

If the experiment is successful, the pig can continue its happy life with a more powerful heart.

In order to find such a pig with symptoms of heart failure, the experimental group searched several pig farms before finding it.

Pig farmers are a little puzzled why they spend more money to buy a faulty pig.

After both the human and the pig were ready, the operation officially began.

Although this operation is only an experiment, and the object is pigs rather than humans.

But the doctors are still very serious, putting the same level of attention into normal clinical operations.

After five hours of surgery.

The whole experiment is finally complete.

After the operation was over, Gong Rui and others walked out of the operating room.

Gong Rui's expression was relatively relaxed, and it could be seen that the whole operation was very successful.

"After the artificial heart implantation, all the physiological signs of this pig are very normal. After the anesthesia period is over, you can see the postoperative reaction of this pig."

Gong Rui was the chief surgeon of this operation, and his superb technique played a key role in the whole operation.

Of course, the more important point is Xu You's exquisite design of this new artificial heart.

Just looking at the physiological indicators of this pig after receiving the artificial heart transplantation, Gong Rui knew that the design of this artificial heart was really excellent.

Not only in terms of materials, but also replaced with better bio-adaptable materials.

In many other details, it is also more optimized than the previous artificial heart.

Although the temporary state of the pig is not decisive for the evaluation of the heart, and the performance of the pig implanted with an artificial heart cannot fully represent that humans will have exactly the same performance after receiving this kind of surgery.

But this is already the most convincing proof before conducting human clinical trials.

After a short period of joy, Xu You and Gong Rui studied the next plan.

"I think we can quickly start the preparation of the second new artificial heart. With such performance, it is true that a lot of testing work can be omitted."

If it can be done in one step, there is no need to carry out the intermediate steps.

This progress was much faster than planned, making it possible for Wang Xiangwu to receive a new type of artificial heart transplant.

In the following days, the team continued to prepare the second new artificial heart.

Due to technological limitations, it is currently impossible to prepare such artificial hearts in batches at the same time, and can only be produced one by one.

On the other hand, the pig that received the artificial heart implant also slowly recovered.

With the support of a powerful new artificial heart, the pig appeared to be full of vitality, not weak at all.

This also gave Xu You and Gong Rui greater confidence in Wang Xiangwu's surgery.

Before Wang Xiangwu's formal operation, Gong Rui once again informed Wang Xiangwu and his family of the situation of the new artificial heart in detail, and asked them to make a final choice.

"The current situation is that the old artificial heart has relatively more cases and the technology is more mature, but its performance is not so good. The new artificial heart has no human clinical cases and has not been fully tested, but its performance Definitely much stronger."
