What a thrilling experience to have surgery in space?
Groping above his head is human imagination. Today, we are closer than ever to approaching colonization in space. However, before we talk about the stars and the sea, we still have a lot of realistic issues to consider.
So far, people who have flew out of Earth's orbit and have visited outer space are strong and extremely healthy astronauts, and they have not been in space for a long time. If ordinary people want to make long-distance space Travel, medical problems can not be skipped.
Up to three astronauts are currently stationed in international space. If they present a health problem, the preferred strategy is to rush to Earth. However, this method is not that the almighty space is still sitting on the Earth's orbit, and it is not too far away from the ground; and the fastest time to return from Mars to Earth is 9 months.
Maybe someone will think about the short-term robot surgery. That's right, the short-range surgical robots led by the Da Vinci Surgical System have made a good breakthrough: as of June 2014, there are more than 3,000 Da Vinci Surgical Systems in the world, which can be approached by surgical doctors every year Millions of operations have been performed around the world.
In other words, the doctor on the earth cuts a mouth, and it will take 4 to 22 minutes before the knife can be cut on Mars, and it will take another 4 to 22 minutes for the doctor on the earth to see the image of the incisive teeth.
Such a delay can not complete the operation that requires close inspection and quick response. In case the scalpel accidentally cuts through the artery, the surgeon on Mars may have lost blood before the doctors of the earth noticed it.
Therefore, short-range surgery is not possible. If you want to undergo surgery in Taibai, you must include an entire surgical team including doctors, assistant doctors, surgeons, and anesthesiologists.
In addition to complex steps, you also need to take care of all kinds of professional equipment. The storage space on the existing spacecraft is scarce. Even water and oxygen are saved, let alone take care of the special operating table, Ventilator, even a huge MRI machine.
At present, someone has come up with a processing method, which is 3D printing. Humans don't need to have a small hospital on the spacecraft, just load the drawings of various machinery into a database that can be printed. When it is needed, use a 3D printer to make the required machinery.
This will not only obscure the doctor's vision, but also the fine instruments on the spacecraft. In addition, if there is a virus or bacteria in the blood, there is a great risk of infection.
If laparotomy has to be performed, then the intestines may be floating down without force. This will not only hinder the operation, cause dislocation of the intestines, but also cause the contents of the intestines to leak. It's all risk.
The intestinal wall is filled with bacterial feces, which may run into other parts of the patient's body, and may run to the blood vessels along the mouth; it will also pollute the entire spacecraft. This will be a terrible disaster.
Healthy people ’s blood pressure and bones are showing signs of disagreement, and what about sick people? Before Taibai surgery is actually underway, humans must update existing medical knowledge. At present, NASA has been conducting medical experiments under the premise of mimicking space, studying the influence of drugs and the development environment of stem cells under a slight force.
In the future, human beings still have a long way to go, but scientists are indecent and after having enough academic savings, humanity will surrender to the world.
