Chapter 1242 Discussion

Living in a gravity-free or low-gravity environment for a long time, astronauts who grew up on the Blue Planet will clearly feel that the blood, lymph and other fluids in their lower body will flow to the upper body more than on the ground of the Blue Planet, which has always caused facial swelling, increased blood pressure in the head, and varicose veins in the neck.

Living in outer space is already very difficult, and if you need to undergo surgery, it will be a terrible disaster.

The orbit of the International Space Station is only 400 kilometers away from the Blue Planet, but all astronauts in the space station who need surgery take sedatives and other drugs to stabilize their state when drugs are completely ineffective, and then contact the astronaut's agency on the ground to transport him back to the Blue Planet, and then perform surgery on the ground of the Blue Planet.

However, this method is unlikely on the lunar base. In recent years, the American Orion spacecraft has carried out a mission to orbit the moon and return to the earth.

Launched by the rocket carrying out the Artemis 1 mission, it will return to the blue planet after orbiting the moon. The total journey takes 25 days and 10 hours, taking into account the extreme environment on the way to and from the moon and on the moon, including microgravity, high levels of radiation, closed pressurized cabins, and special space suits.

An astronaut who continues to perform surgery to save his life basically cannot persist until returning to the blue planet from the moon and then adjust his physical condition until he can undergo surgery.

The concerns of these academicians and scientists are not saints, but problems that must be solved by aerospace projects.

From a young age, if a few elites are sent up, everyone can still trust each other's physical fitness, and no surgery should be required in the short term, but once the number of people expands, there will be hundreds or thousands of people on the lunar base, and the unexpected situation will be magnified countless times.

No one wants to cast a bloody shadow on this project, and in the future, when space travel becomes popular and the lunar base is to be expanded, there will inevitably be many ordinary people with average physical fitness who have not undergone years of training entering the lunar base, and there will definitely be medical needs at that time.

If it is not solved now, will there be a solution when the problem arises?

Isn't that a disguised form of taking human life lightly?

This group of crazy scientists is not so arrogant as to ignore life.

During the quarrel, Gu Qing pushed away the display screen, stood in the center of the discussion area, and said: "Living in a low-gravity or zero-gravity environment for a long time will greatly affect the blood pressure, internal organs, and muscle function of astronauts, and all of them are inferior impairments, so the need for surgery is more important than that of ordinary people. At the same time, everyone should not ignore that due to the weakening of physical fitness, astronauts are more susceptible to bacterial and viral infections.

At the same time, under the multiple radiation exposures in outer space, some pathological tissues that are not usually found may become active, which is also extremely detrimental to the physical health of astronauts.

We have equipped astronauts with medical robots and engineering robots to reduce the possibility of injuries to astronauts at work, and at the same time monitor and control their diet, sleep and mental state to avoid appendicitis, cholecystitis, and stomach pain. (The stomach is an organ that is affected by emotions, so everyone should keep a healthy mood)

But these are just to reduce the need The probability of surgery cannot completely eliminate surgery.

We also have medical reforms and innovations, such as learning to use magnetized surgical tools like the International Space Station. These surgical tools can be attached to the operating table at any time so that they will not fly around due to weightlessness.

There are also minimally invasive surgeries, such as keyhole surgery, which only requires a small incision on the patient during surgery, and can be perfectly completed in the abdominal cavity using cameras and surgical instruments.

Of course, there are many other difficulties to overcome. For example, the patient's body fluids will have a great change in surface tension because they are in a state of weightlessness. Liquids such as blood and urine will adhere to instruments and other tissue structures, and even float up to form mist to interfere with the doctor's vision and camera collection.

At the same time, because the surgical environment needs to be closed, it will increase the risk of infection for patients, and it is also a great test for the doctor's physical strength, observation and psychological quality. "

Gu Qing's narration gradually calmed the discussion in the laboratory.

Whether it is academicians and doctors in their sixties and seventies, or those middle-aged scientists and young experimenters, they all listened quietly.

Although the boss of the company talked about the problems that most people in the industry knew, the aerospace project is so complicated that how can a person who works on machinery know more than a person who works on human biology?

The more knowledgeable a person is, the more humble he is.

There were a few young people who originally thought that they had to take risks in the early stage, but they began to calm down and follow Gu Qing's narration to think about solutions to break the deadlock.

Everyone is actually very confident about rockets sending spacecraft to the sky, but the traditional concept of Daxia believes that things cannot be concluded early before they are done, so they will discuss it many times.

The big problem of outer space surgery is a problem that no one can solve, but many people on the scene may have to face in the future.

Gu Qing raised his head and looked at the academicians beside him who were also listening attentively. He was calm but very emotional.

At the retirement age of more than 70 years old, he signed a confidentiality agreement and had to work on his own projects. Sometimes he knew the correct answers to certain projects, but because of many rules, he could not speak out. He could only direct students and other experimenters to tinker with various things and replicate the steps of their original solutions.

And they don’t need an annual salary of tens of millions. They really guide students and look after projects. It’s really like having an old man in the family is like having a treasure…

In order to meet the urgent health needs of these researchers and astronauts, Gu Qing snapped his fingers and pulled out a proposal for designing multiple major industries from his database.

Then he analyzed to a group of scientists, academicians, and professors: "The environment in outer space is harsh, unlike the blue planet that can provide me with a safe environment, so we have to develop a new medical system. Whether it is the so-called traditional Chinese medicine, Western medicine, or modern medicine, we must learn from others and make substantial innovations.

First, we have to solve the key problem, the operating room and surgical tools.

Magnetic surgical tools only solve the problem of tools being scattered due to gravity, and we also need to develop new surgical tool materials and coatings so that they are not contaminated with liquids and have sharp and stable characteristics.

We also need to develop a closed surgical space that can handle bacteria and viruses at any time, so that the fluids in the patient's body can be optimally treated and provide a good surgical environment for the surgeon."
