[A collection of short videos of popular science and modern medicine. 】
[Nine: Artificial organs. 】
[Artificial organs, in biomaterial medicine, refer to materials that can be implanted into the human body and can come into contact with biological tissues or biological fluids, or materials that have the functions of natural organs and tissues or natural organ parts. 】
[The birth and development of artificial organs have also taken a lot of twists and turns. 】
[The myth of "lotus and lotus leaves spliced to reshape Nezha's body" in China is the first in China, indicating that the ancient people had the idea of artificial organs. 】
[The later "willow branch bones" is also an attempt. 】
[In fact, the same is true abroad, about 200 years ago, a scientist in Bolan suggested that artificial crystals be implanted in the eyes to restore sight to cataract blind people. 】
Unfortunately, people don't believe it. 】
[Someone actually accused him of "deceiving the public with evil words and swaggering and deceiving", so he was imprisoned for a time. 】
[After more than 100 years, the prophecy of this Bolan scientist was fulfilled by an ophthalmologist named Gared. 】
[At that time, the doctor accidentally discovered that the plexiglass piece left in the eye of a pilot during the operation had not 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 lens made of plastic.] 】
[As a result, the patient weighed 233 and saw the colorful world.] 】

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 biologically inactive polymer materials to imitate an organ, and with the help of a battery as the power of the organ. 】
[Semi-mechanical, semi-biological artificial organs:]
[Semi-mechanical, semi-biological artificial organs are the combination of electronic technology and biotechnology. 】
[In Germany, 8 patients with liver failure have been transplanted with artificial livers, which are a wonderful combination of human living tissue, artificial tissue, chips and micromotors. 】
[It is expected that in the next ten years, this bionic organ will be widely used.] 】
[Biological Artificial Organs:]
[Biological artificial organs are the use of cells or tissues in animals to "make" some biologically active organs or tissues. 】
[Biological artificial organs are further divided into, allogeneic artificial organs, and autologous artificial organs. 】
[For example, experiments have been successful in cultivating human organs in pigs, mice, dogs, etc., while autologous artificial organs use the patient's own cells or tissues to grow human organs.] 】
[The first two artificial organs and allogeneic artificial organs will cause patients to have a rejection reaction after transplantation, so the ultimate goal of scientists is that patients can use autologous artificial organs.] 】
Nobel laureate Gilbert believes: "In less than 50 years, human beings will be able to cultivate all the organs of the human body by bioengineering methods.] "】
[Scientists optimistically predict that in the near future, doctors only need to remove cells from the patient's body according to the patient's own needs and implant them on a pre-computer-designed structural scaffold, and as the cells divide and grow, the grown organs or tissues can be implanted into the patient's body. 】

[Significance of artificial organ research:]
[Some people are born with some organs mutilated, and some people lose an organ due to an accident. 】
[These people have spent their entire lives in pain. 】
[On the other hand, there is a serious shortage of donated organs in the hospital, resulting in many people being unable to match suitable transplanted organs.] 】
[According to statistics, about 300,000 patients in China are waiting for organ transplantation due to organ failure every year, but there are only more than 10,000 organ transplants every year, and most patients are waiting. 】
【......】
[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) hearts and heads was enough to give people transgender!
I can't think of anything more rebellious!!
"Ah??? our mythical story of Nezha's rebirth has been reorganized by future generations!
"Yes, we just listen to myths and stories, and you really do it for future generations!"
"Amazing! They can even make something that people are born with!?"
"I'm really convinced, people in later generations dare to do anything, can they do anything?" (read violent novels, go to Feilu Novel Network!)
“......"
Qin Dynasty.
The doctors were numb.
No, you have to slow down, otherwise your heart won't be able to stand it.
They knew that the people of the Mo family liked to make some strange things, and some creations could really help the sick.
But it's not like the light curtain says, just make an organ out!
And since it can be made, it will definitely be able to be used.
The people of the medical family only felt that they had to study the medical skills for many years, and they had not even learned the skin, and they all fell into autism.
Han dynasty.
The medical saint Zhang Zhongjing's eyes widened.
It's like seeing a ghost in broad daylight!
I almost screamed!
"It can't be..."Zhang Zhongjing subconsciously muttered: "How can man-made things replace the internal organs..."
If he wants to say that people can make prosthetic limbs, he is willing to believe it.
But the operation mode of the internal organs is too complicated, how did future generations figure it out?
Not to mention breeding on pigs, dogs, and rats!
Neither is a species at all!
Zhang Zhongjing's blood pressure in his brain increased, and he hurriedly sat on the ground and slowed down.
Three Kingdoms period.
Hua Tuo, who went home happily, was excited.
He used to be apprehensive about cutting on people, but now he sees that even organs can be made.
This gave him a lot of confidence!
Hua Tuo roared in a low voice: "When I go back, I will definitely be perfect for numbness! I can also do the surgery that future generations can do." "
[Here are ten artificial organ technologies.] 】
