This time the operation of "implanting the prosthetic substrate" is actually quite simple.
The prosthetic substrate itself is advanced enough.
If the requirements are low enough, this operation only requires two steps. The skin tissue in the implantation area is peeled off to expose the dense connective tissue.
Then, attach the base plate.
It's over.
During the entire operation, there are almost no requirements for hemostasis. On the contrary, the recipient needs to use anticoagulant drugs in advance to ensure that the blood does not coagulate into a ball in the loose gaps in the bone substrate.
Blood and body fluids will gradually infiltrate the bone part of the base plate and come into contact with the metal part embedded on the outside of the base plate.
The bone part is made of Lu Xuanyu's own osteoblasts cultured in vitro and then 3D printed. Some of the multipotent stem cells and signaling factors that induce differentiation are also mixed into it.
The gaps in the bony base plate will gradually form mature dense connective tissue and blood vessels, tightly fixing the base plate to the body, as if it was born like this.
The metal part bites closely with the bone part.
For athletes like Lu Xuanyu, it is just a matter of connecting a few extra data lines to the end of the spine.
Of course, if Lu Xuanyu is willing to further replace bones and the like, Superman Enterprises still has many mature products that have been tested on animals.
It's just that Lu Xuanyu doesn't have any need in this area yet.
What Lu Xuanyu needs to do now is to stay fixed in one place for a period of time without moving to avoid mechanical damage to the connective tissue that has not yet completed its growth.
Under the influence of a certain drug, Lu Xuanyu lay lazily and really didn't want to move.
While half asleep, he seemed to see someone coming to visit him. It seemed like some relative of his own family. Yawgmoth seemed to be passing by with someone outside the ward and took a look. Florence had been with Xiang Shan
Come forward and comfort his family.
When he finally woke up, the straps on his body had been removed.
Lu Xuanyu reached out and gently touched the "lower" area of his body. It was a metal plate with a hydrophobic treatment on the surface and uneven interior.
What made him somewhat embarrassed was that there were two pipes at the end of the prosthetic body, one thick and one thin. There was a soft mechanical structure at the end of the pipe.
Lu Xuanyu did not continue touching it.
When working on projects with Chen Feng, Lu Xuanyu also connected many different prosthetics. Such very soft things most likely contain layered pressure-sensitive components, which can reproduce the sense of touch in more detail.
The part of the body this thing corresponds to is very clear.
He will not receive tactile signals until doctors activate the pathway.
But it's really weird to play with artificial urethra and artificial intestine like this.
The battery pack of this prosthetic limb is placed separately. There will be one in the crotch, and then there are independent batteries in the thigh and calf. This is not because of anything else, but because the space is so large. In order to ensure that the appearance is closer to humans, the battery has to be like this
Install.
Xiangshan actually believes that baseline humans can free up space in the abdominal cavity by shortening the intestines. Metal-based organisms can rely on electric field energy to survive and have less demand for nutrients, so appropriately shortening the intestines will not have negative effects.
Rather, the length of the intestinal tract of baseline humans is directly inherited from Homo sapiens. This length can be considered “too long”.
In addition, there is evidence that when food sources are sufficient, the utilization rate of electric field energy by metal-based organisms cannot be improved. Aerobic respiration and electric field energy occupy two different reaction routes.
Among the enzymes that support aerobic respiration, key parts include hexokinase, phosphofructokinase, pyruvate kinase, pyruvate dehydrogenase complex, citrate synthase, etc. In addition, the respiratory chain also involves a large number of coenzymes.
The enzymes that support the utilization of electric fields are composed of several enzymes that can form complex reaction pathways in electric fields.
There is only so much material that can be accommodated in a cell. If there are more substances on one side, they will naturally crowd out the other side.
To sum up, in fact, baseline people may be healthier if they eat less.
Xiangshan even had plans such as "swallowing soft floc that cannot be digested" - this was to combat the "empty feeling".
Anyway, this thing can easily lead to obesity and diabetes in Homo sapiens, and it can already be regarded as a physical defect for modern people.
It's just that the number of baseline people is currently very small, so these are only in the plan in Xiangshan's personal terminal.
Most of those "fighting the feeling of hunger" solutions are not as convenient as "directly reducing the size of the digestive system" and can also make room for more components in the body cavity.
However, Lu Xuanyu doesn't need to worry about this yet.
He just needs to wait for recovery.
The next day, Chen Feng also came to visit with gifts.
"Try it...ah, sister, you'd better not eat it. It may cause metal poisoning for Homo sapiens." Chen Feng said to Lu Xuanyu, holding a fruit basket that looked bright and unusual in color and not like the real thing, "Just now
The new varieties that have been cultivated are still luxury goods and are not available to ordinary people."
Lu Xuanyu picked up a blue-green fruit - he didn't know whether it was an apple or a pear. He took a bite and felt it was extremely sweet.
Lu Xuanyu's wife stayed in the ward for a while and then went out to escape the heat. Although she really wanted to spend more time with her husband, the temperature was really unbearable.
The cooling system of clothes also needs to dissipate heat.
Seeing that there was no one else around, Lu Xuanyu thought for a while and told Chen Feng about Xiang Shan's search for him.
"Ah, this matter." Chen Feng said to Lu Xuanyu apologetically: "Indeed, maybe I am too impatient. If we really want to discuss it, Xiang Shan and the others are correct."
Lu Xuanyu scratched his head: "I know all these things and agree. It shouldn't be a particularly serious problem."
Chen Feng looked at the ground: "From the perspective of animal experiments, I can indeed infer that those experiments will not cause long-term adverse effects. But Xiangshan's approach is safe - what if?"
"A genius like Yawgmoth might fail, let alone an ordinary researcher like me."
"As for your agreement... our knowledge gap in this field is huge. If you have more bad intentions, you can tell the truth, but it will induce you to think that 'the problem is not serious'."
Lu Xuanyu was shocked: "Is there such a thing?"
"I used to be a popular science writer. Take medicine as an example. There are many people who sell anxiety. They will extract some results from some papers with a small sample, and then publicize 'what may cause serious consequences.' This conclusion
Every word is a rigorous scientific description, and of course it is not a lie. But... you know." Chen Feng said: "The converse is also the same. Statistics cannot lie to people, but they can also deceive people very well."
