Military Technology

Looking at everyone's confused looks, Wu Jiuzhi said with a smile: "There are many hormone drugs we use daily, such as many skin ointments, which contain hormones.

Some anti-inflammatory, anti-allergic, and anti-shock drugs also contain hormones. Even insulin, which many people use, is also considered a hormone.

Then there is the epinephrine used in emergency rescue, which can also be regarded as a kind of hormone.

So don’t talk about the discoloration of hormones. Use them normally and strictly according to the doctor’s instructions. There will be no problems. "

Speaking of this, Wu Jiuzhi glanced at everyone present, and then continued: "Our human body cannot be separated from the stimulation of various hormones, even the division and growth of cells cannot be separated from hormones.

Of course, this must be controlled within a reasonable range. Too little or too much will affect cell division and growth. "

Through this cell clonal cultivation technology, we can obtain a large number of clonal culture cells. This process may last for more than ten hours or even several days. Of course, with the continuous advancement of this technology, it is said that the latest technology can now control the clone cultivation time of the entire cell within twenty-four hours.

Having said this, Wu Jiuzhi looked at Wu Hao and asked him for confirmation. After hearing this, everyone also looked at Wu Hao, waiting for his answer.

In response, Wu Hao smiled and nodded and said: "Actually, it's not a new technology. It just increases the number of cell clones and conducts multiple groups at the same time. This speeds up the entire clone cultivation time."

Hearing what Wu Hao said, everyone looked surprised and laughed.

So it's just about adjusting the speed, and it also involves very few issues. It can affect the whole body. "

For example, if the printing speed is slowed down, the center of the printing needle will be blocked by cells flowing in slowly, causing a malfunction. Secondly, if the flow rate in the cell supply system is too slow, it will also cause damage to the cells to be printed.

But that is printing living organs and tissues, so the time requirement is relatively tolerant. Obviously, special stacked 3D printers that require a long printing process are suitable.

Like some small organs and tissues, you have a way to print them, but you can always print only half of them. "

That kind of printing speed is too fast. You must know that the optimal time for transplantation of human organs before leaving the body is within 8 hours. Some organs may even be damaged after a few hours, which is a recoverable loss.

As for Wu Jiuzhi, he also smiled and continued: "The cells that have been damaged by cloning will be degenerated and preserved, and then sent directly to the biological 3D printer for degeneration and printing.

The same goes for the printed organs and tissues. If Fang Xin prints for too long, the printed organs and tissues will lose their activity and become a piece of dead meat. Even if the prescription time is too long, it will smell bad. How can it be implanted into the patient's body?

Just after that, a slight problem occurred. It was not that the printing speed was too fast. Then there may be no minor problem under the square center object, just print it out.

In order to ensure that the consumables required during the entire printing process are not the freshness of the cloned and cultured organ tissue cells, so during the entire printing process, a steady stream of fresh cells cultured in the cultivation equipment will be transported over and directly supplied to The biological 3D printer performs advanced printing to ensure that the printed organs and tissues are fresh and vibrant enough. "

When I think about it, Xiaojia loses her balance both internally and externally. Yes, we are good, but Wu Hao and we are too good.

That is obviously possible, because the internal structure of each organ and tissue is very precise. Once the accuracy decreases, it will slightly affect the function of the organ and tissue, and may even cause the entire organ and tissue to become deformed and produce lesions. Then printing The organs and tissues that came out can obviously be implanted into the patient's body.

Just like the end, you can only print some large skin tissue, blood vessels, nerves, muscle tissue, etc., which are larger in size.

Having said that, Wu Jiuzhi breathed a sigh of relief, then slid the transparent tablet under his hand to change the content on the small screen, and then introduced it.

It's just that the stacked 3D printer has no shortcomings or disadvantages, which makes the printing process very fast. Especially the low-precision printing process is very fast. It often takes several hours, or even a dozen hours, to print a large object.

The same is true for that biological 3D printer. Its principle is not to use cells that are only a few microns visible to print a huge organ.

This is not to increase the overall printing speed, but to control the printing time of the entire organ tissue in a shorter cycle, thereby maintaining the activity of the printed organ tissue.

Therefore, there are lower or even more stringent requirements for the overall performance of biological 3D printers. It is required to increase the printing speed while ensuring printing accuracy, thereby ensuring that the required organs and tissues can be perfectly printed in the shortest time.

After hearing Wu Jiuzhi's introduction, everyone present finally understood the ease of that technology. Thinking of that, Xiaojia also felt relieved. Thinking about it, if that technology is really a breakthrough, only Haoyu Technology may not be able to make it for such a long time.

The same goes for the biological 3D printer. Through stacked printing, the required organs and tissues are printed out layer by layer.

Having said that, Wu Jiuzhi sighed and said: "It is difficult to solve that problem, because it is very difficult to speed up that kind of biological 3D printer. The consumables it uses are cells, and what is printed are living organs and tissues. , those are all lifeless.

But as you know, if the overall printing speed is definitely increased, this means that the printing accuracy of organs and tissues will decrease accordingly.

It has been pre-processed, and it must have not been processed, so it is not a piece of dead meat and can be used in any way. It may even stink over time.

Having said that, Wu Jiuzhi paused for a while, and then continued: "And that problem also restricts the size of the printed organs and tissues. It does not mean that its printing speed and accuracy determine what organs and tissues it can print. .

Therefore, how to keep printed organs and tissues active for a long time has become the most difficult problem facing the scientific research and technical team.

Therefore, that brings about various constraints and problems of being unprepared.

“Everyone knows that 3D printing is not about cutting, melting and stacking consumables to form specific items.

Take larger organs such as the heart and kidney, which are most unfamiliar to you, for example. If you want to print them using cell stacks, it will take at most several weeks.
