Chapter 371 This is a lucky pig
Gong Rui was also surprised when he heard Xu You's words.
"Professor Xu, normally, after we prepare a new artificial heart, we need to conduct in vitro testing first. Based on the test results, we will then optimize the entire artificial heart to ensure that it can perform all the functions of a biological heart."
Gong Rui thought Xu You didn't know the normal research and development process of artificial hearts, so he hurriedly explained it to Xu You.
Because the artificial heart is a very sophisticated structure, it is impossible to design it successfully in one go, and multiple tests must be carried out in the process.
If biological testing were carried out directly after the design and preparation were completed, the result would almost certainly be that the animals receiving the transplant would die directly.
The death of a pig is naturally not a big deal for humans.
However, a lot of manpower and material resources will be consumed during the operation.
A surgical experiment that is bound to fail is not that meaningful and will instead delay normal progress.
"Professor Gong, I can guarantee that the artificial heart I designed can pass these in vitro tests . Time is very tight now, and we can't waste any more time."
Waste a few days here, a few days there, and soon a month is up.
By then, if the new artificial heart is not ready, Wang Xiangwu can only implant an old-fashioned artificial heart whose performance is not very powerful.
Even if the operation is successful, it will be difficult for Wang Xiangwu to live a normal life like an ordinary person.
After hesitating for a moment, Gong Rui nodded heavily.
"Okay, Professor Xu, we'll proceed according to your plan. We'll hurry up and produce your new artificial heart, and then immediately conduct animal artificial heart implantation experiments."
"Thank you Professor Gong for your trust." Xu You said politely.
Gong Rui waved his hands and said, "Professor Xu, you are wrong. This is not your job. We are very touched that you can help us. This is not only a contribution to Professor Wang, but also to the entire medical community."
Under Gong Rui's arrangement, the new artificial heart designed by Xu You soon entered the preparation stage.
3D printing technology is very practical for preparing artificial hearts, which are 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 being observed in the hospital for a few days, Xu You did not show any new symptoms and was allowed to be discharged.
Xu You was anxiously waiting for the news that 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 experiments on implanting a new type of artificial heart on animals.
As the designer of this heart, Xu You also came to the experimental site to observe the operation.
The experimental organism this time is a pig.
Because the structure of pig hearts is very similar to that of humans, artificial hearts are usually tested on pigs before clinical trials.
There are even cases where pig hearts were directly transplanted into humans.
This experimental pig selected is a very lucky pig.
Considering the experimental objectives, this experiment did not select a healthy pig, but instead selected a pig that already had symptoms of heart failure.
In this way, the performance of this new artificial heart can be better evaluated and it is less likely to cause resistance from pig lovers.
If the experiment is successful, the pig can continue its happy pig life with a more powerful heart.
In order to find a pig with symptoms of heart failure, the experimental team searched several pig farms before they found it.
Pig farmers are somewhat puzzled as to why they would spend more money to buy a pig with problems.
After both the people and the pigs were ready, the operation officially began.
This operation was just an experiment, and the subjects were pigs instead of humans.
But the doctors are still very serious and attach the same level of importance to it as normal clinical operations.
After five hours of surgery.
The whole experiment was finally completed.
After the operation, Gong Rui and others walked out of the operating room.
Gong Rui's expression was relatively relaxed, and it was obvious that the entire operation was very successful.
"After the artificial heart was implanted, all the physiological signs of this pig are very normal. When the anesthesia time is over, we can see the pig's postoperative reaction."
Gong Rui was the surgeon in charge of this operation, and his superb skills played a key role in the entire operation.
Of course, the more important point is Xu You’s ingenious design of this new artificial heart.
Just by looking at the physiological indicators of the pig after receiving the artificial heart transplant, Gong Rui knew that the design of this artificial heart was indeed outstanding.
Not only the materials have been replaced with better biocompatible materials.
In many other details, it is also more optimized than previous artificial hearts.
Although the temporary condition of the pig is not conclusive for the evaluation of the heart, the performance of a pig with an artificial heart implanted cannot completely represent that humans will have exactly the same performance after undergoing this surgery.
But this is already the most convincing proof before conducting human clinical trials .
After a brief moment of joy, Xu You and Gong Rui began to discuss the next plan.
"I think we can quickly start the preparation of the second new artificial heart. With such performance, a lot of testing work can indeed be omitted."
If you can achieve it in one step, there is no need to go through the intermediate steps.
This progress, which was much faster than planned, made it .
In the days that followed, the team continued to prepare the second new artificial heart.
Due to technological limitations, it is currently impossible to produce this type of artificial heart in batches at the same time, and it can only be produced one by one.
On the other hand, the pig that received the artificial heart implant is slowly recovering.
With the support of the powerful new artificial heart, the pig appears to be full of energy and is no longer as weak as before.
This also gave Xu You and Gong Rui greater confidence in Wang Xiangwu's surgery.
Before Wang Xiangwu officially underwent the operation, Gong Rui once again informed Wang Xiangwu and his family in detail about the new artificial heart and allowed them to make the final choice.
"The current situation is that the older artificial hearts have been used in more cases and the technology is more mature, but the performance is not that outstanding. The new artificial hearts have no human clinical cases and have not been fully tested, but their performance is definitely much better."
