I make a popular science video and all the emperors learn from it!

【9: Artificial Organs】

【In biomaterial medicine, artificial organs refer to materials that can be implanted into the human body and come into contact with biological tissues or biological fluids; or materials that have the functions of natural organ tissues or natural organ components.】

【The birth and development of artificial organs has also taken many twists and turns.】

【The earliest Chinese myth of"reshaping Nezha's body by splicing lotus flowers and lotus leaves" shows that ancient people had the idea of ​​​​artificial organs.】

【Later"willow branch bone grafting" was also an attempt】

【In fact, this is also the case abroad. About 200 years ago, a scientist from Poland suggested using artificial crystals to implant into the eyes to restore sight to those blinded by cataracts.】

【Unfortunately, people not only do not believe】

【Someone actually accused him of"deceiving people with evil words and cheating", so he was imprisoned for a time】

【It was more than 100 years later that the prediction of this Polish scientist was realized by a Korean ophthalmologist named Garrid.】

【At that time, the doctor accidentally discovered that a piece of plexiglass left in a pilot's eye during surgery had never caused inflammation in his eye.】

【So, when he later performed eye surgery on a patient, he boldly replaced the cloudy lens in the patient's eye with a plastic lens.】

【The result enabled the patient to see the colorful world again.】

【......】

【There are three main types of artificial organs:】

【Mechanical artificial organs, semi-mechanical and semi-biological artificial organs, biological artificial organs】

【Mechanical artificial organs:】

【Mechanical artificial organs are completely made of non-bioactive polymer materials to imitate an organ, and a battery is used as the power source of the organ.】

【Semi-mechanical and semi-biological artificial organs:】

【Semi-mechanical and semi-biological artificial organs combine electronic technology and biotechnology】

【In Germany, eight patients with liver failure have received artificial liver transplants, which are a wonderful combination of human living tissue, artificial tissue, chips and micromotors.】

【It is expected that within the next ten years, such bionic organs will be widely used】

【Biological artificial organs:】

【Biological artificial organs use cells or tissues from animals to"create" some biologically active organs or tissues.】

【Biological artificial organs are further divided into allogeneic artificial organs and autologous artificial organs.】

【For example, experiments on growing human organs in pigs, mice, dogs, etc. have been successful; while autologous artificial organs use the patient’s own cells or tissues to grow human organs.】

【The first two types of artificial organs and allogeneic artificial organs will cause rejection reactions in patients after transplantation. Therefore, scientists’ ultimate goal is that all patients can use autologous artificial organs.】

【Nobel Prize winner Gilbert believes:"In less than 50 years, humans will be able to use bioengineering methods to grow all the organs of the human body."】

【Scientists optimistically predict that in the near future, doctors will only need to remove cells from patients according to their own needs and implant them into structural scaffolds pre-designed by computers. As the cells divide and grow, the organs or tissues will grow. can be implanted into the patient's body】

【......】

【The significance of artificial organ research:】

【Some people are born with partial organ defects, and some people lose certain organs due to accidents, etc.】

【These people spend their lives in pain】

【On the other hand, there is a serious shortage of donated organs in the hospital's inventory, resulting in many people being unable to match suitable transplant organs.】

【According to statistics, about 300,000 patients in China are waiting for organ transplantation due to organ failure every year, but only more than 10,000 organ transplant surgeries are performed each year, and most patients are waiting patiently.】

【......】

【However, the development of science and technology has brought good news to patients with organ defects.】

The ancients were completely shocked.

I thought that changing (dbea)'s heart, changing his head, and changing someone's gender were enough to go against the will of heaven!

I can't believe there's something even more outrageous!!!

"ah? ? ? Our mythical story of Nezha’s rebirth has been rectified by future generations! What else can't they do?"

"Yes, we just listen to it as a fairy tale. Future generations, you really do it!"

"Astonishing! They can actually create something that is something a person is born with!! ?"

"I am really convinced. People in future generations will dare to do anything and can achieve anything, right?" (To read exciting novels, go to Feilu Novel Network!)

"......"

Qin Dynasty.

The doctors were almost numb from the shock.

No, you have to take it slow, otherwise your heart won't be able to bear it.

They know that the Mohists like to make some weird things, and some of their creations can really help patients.

But there is no way to directly create an organ as the light curtain says!

And since it can be made, it can definitely be used.

The medical people only feel that they have to study hard for many years in medical skills, and they have not even mastered the basics, and they all fall into autism.

Han Dynasty.

Medical Saint Zhang Zhongjing’s eyes widened.

It was like seeing a ghost in broad daylight!

I almost screamed!

"It's impossible..."Zhang Zhongjing murmured subconsciously:"How can man-made things replace the internal organs?"..."

If people can make prosthetic limbs, he still wants to believe it.

But the way the internal organs operate is too complicated. How did future generations figure it out?

Not to mention breeding it on pigs, dogs, and mice!

The two are not the same species at all!

The blood pressure in Zhang Zhongjing's brain increased and he quickly sat on the ground to relax.

Three Kingdoms period.

Hua Tuo returned home happily and was very excited.

He used to be wary of operating on people, but now he sees that even organs can be created.

This gave him great confidence!

Hua Tuo roared:"When I go back, I will make sure to perfect the anesthetic powder! I can also do the surgeries that future generations can do.""
