I have opened a new book "I Level Up in Xiaobaiwen", and I sincerely ask all book friends to bookmark, recommend, and leave a message! Ants thank you!

*****************

If it is a traditional operation, the doctor uses the operation mode, so it is easy to find the operation area and expose the operation field.

However, although this approach is simple and effective, it also has many disadvantages.

For example, a large area of ​​the abdominal cavity is exposed, and the patient's organs are exposed to the air, which is likely to cause postoperative infection.

And the large amount of antibiotics used after the operation can easily destroy the patient's own immune system, and the recovery after the operation is very slow.

And it is easy to be accompanied by a large number of postoperative complications.

It is precisely for this reason that doctors have developed the method of laparoscopic surgery.

But laparoscopic surgery also has disadvantages, that is, it is always done in two-dimensional image quality, and an assistant is needed to hold the mirror during the operation.

In many cases, the lens holder cannot fully understand the doctor's intentions, which can easily cause the surgical field to be unclear, and the doctor cannot see the surgical field he wants to see, but he can't interrupt the operation and give the holder The mirror explained.

Therefore, the effect of surgery is often easily discounted.

And because it also requires multiple people to operate, it takes up a lot of space, so this minimally invasive surgery is only suitable for some simple operations.

And later, because of some children patients, some critically ill patients, and many elderly patients with poor physical fitness but urgently in need of surgery appeared in large numbers.

Doctors, consider using minimally invasive surgery for these people.

At this time, surgical robots appeared at the right time.

And this surgical robot is actually an upgraded version of the original laparoscopic surgery.

Only this time, the doctor is working on the operating table, and the one performing the surgery is replaced by a robotic arm.

And this time the mirror is also held by a robotic arm, so that the surgeon can better and more intuitively let the mirror-holding robotic arm reach the surgical area he wants to see.

At the same time, other robotic arms that perform surgical actions must also safely arrive at the surgical area.

However, in this process, the surgical navigation technology mentioned earlier will be used.

After all, robotic arms are made of iron, which is different from human hands.

After they enter the abdominal cavity, although they only advance a few centimeters, you must plan the travel route of these robotic arms.

Let these robotic arms effectively avoid those key organs, nerves and blood vessels.

Otherwise, if these important organs are damaged by the mechanical arm, it will be in big trouble.

This is why, before using the surgical robot, the doctor will arrange for the patient to do multiple body checks and complete all kinds of perspective imaging.

Because they need to accurately locate the patient's diseased area based on these pictures.

Then they have to build a 3D model, and finally they will perform countless drills on the computer based on the 3D model.

Find out the best route for the robotic arm to enter the operation area, not only to ensure that it does not touch the patient's vital organs, but also to ensure that the operation can be completed smoothly, so that the patient can recover as quickly as possible after the operation.

The Intuitive Sense Company, which currently develops the Da Vinci surgical robot, can be said to be the best company in this field.

Their 3D modeling system is currently the most advanced in the global medical community.

Just input the data from various perspective images into their modeling system.

Soon their equipment will be able to simulate a perfect 3D image group of the patient's body in the computer.

Assisting doctors can find the most reasonable route for the robotic arm to enter the operation area at the fastest speed.

Moreover, the error is extremely small, even reaching one micron as the calculation unit.

In this regard, let alone our country, even Germany and Japan, which have the strongest construction machinery capabilities in the world, are far behind the technology of this powerful American company.

This is why, in the field of surgical robots, even though everyone knows that the profits in this field are very large, they can only watch the Intuition and Senses company dominate.

When Huang Haibin planned to build a robot by himself, this was the most troublesome problem.

Although he has his own ideas about the internal structure design of the robotic arm, as well as the control program and so on.

But when it comes to 3D modeling, he is blind, because this is the core technology of Intuitive Senses.

They have never asked outsiders for help with this technology, and it was developed by their founder himself leading the team.

It can be said that this is their core ability to see, and outside companies simply cannot get a glimpse of it.

This is the main reason why Huang Haibin chose to join the Ninth Laboratory, because this company has the most powerful 3D perspective imaging equipment in the world.

With the help of this equipment, the 3D modeling technology of Intuitive Sense Company can be said to be completely reduced to rubbish and useless.

And he also firmly believes that he is definitely not the only one who can perceive the benefits of this equipment.

There are so many smart people in this world, there must be countless people who thought of combining this set of perspective imaging equipment with surgical robots.

It is hard to tell that there are German and Japanese companies that are already doing it.

It's just that if they want to take out this 3D perspective imaging equipment, they will definitely not be able to take it out alone.

Because the Ninth Laboratory can be said to have done a very good job in this regard.

It is absolutely no problem if the equipment is exported as a whole, but you must find my engineers to do the maintenance in the later stage.

If you disassemble the equipment without authorization and prepare for 'repair', hehe, you will be responsible for the consequences.

It is said that in the United States and Japan, the 3D perspective imaging equipment of the Ninth Laboratory was violently dismantled, which eventually led to accidents.

It is said that some people seem to have lost their lives because of it.

However, these news, so far, are just rumors. The Americans and Japanese will definitely not admit that they have forcibly demolished the equipment of the Chinese.

As for the specific reasons, needless to say, everyone knows.

Now that Xiao Li has left his job to start a business, Huang Haibin, who was still hesitant, finally made up his mind.

He plans to leave his job to start a business, after all, the opportunity lies here.

And he firmly believed that as long as his proposal was written, he would be able to convince the review committee.

And now he has mastered almost 70% of almost all the technical problems of the surgical robot.

If he can convince the Ninth Laboratory to come up with their 3D perspective imaging technology, then he will have completed 90% of the progress bar for overcoming the technical problem of surgical robots.

The last point is still missing, and that is the 3D high-definition camera used on the endoscope.

We must know that in the field of optics, it has not been our country's strong point.

Not to mention this kind of 3D high-definition camera, it is an ordinary camera, and there is a big gap between us and the world's top companies.

Even the mobile phones of company H, which we are so proud of, now use cameras from Sony in Japan.

Even the iPhone of the Light of the Country uses a camera from Sony in Japan.

I won't talk about these cameras here, but just talk about the 3D high-definition cameras used in this surgery.

Because it is necessary to achieve the effect visible to the naked eye, the ordinary endoscopic lens used in ordinary laparoscopic surgery is definitely not applicable.

Because you are operating a robotic arm, in order to achieve the best visual effects, of course it is best to use a 3D high-definition camera.

The imaging mystery of the 3D high-definition camera lies in the fact that the two three-chip cameras used in the background can produce two high-quality images with high definition and color reproduction.

And the two sets of images are respectively output to two surgical operation monitors in the console.

Then, through the 3D image viewer, the two images with slight parallax are sent to the operator's left and right eyes respectively, thus forming a high-quality 3D image.

At the same time, the endoscope lighting adopts high-quality cold light source to optimize the brightness of the light. The operator can obtain the required observation area and magnification by adjusting the depth and angle of the camera.

In addition, an external observation monitor, a carbon dioxide inflator, a light source and a camera are also set up on the imaging system.

The external monitor feeds from one of two cameras, representing either the left or right eye vision.

The imaging system also includes two image synchronizers and a focus controller to achieve controllable high-quality 3D images.

Therefore, the entire imaging system may seem simple, but in fact the requirements for technical content are very high.

In this technical field, there is still a blank in our country.

Huang Haibin also thought that if the previous technical problems were overcome, then the 3D imaging in this operation would be the last problem.

He had sought other solutions before, too.

But after searching almost all the technical information, he felt almost desperate.

At present, in this field, it can be said that the United States is the only one.

Even Japan and Germany, which are quite skilled in the optical field, are technically inferior to the United States in this field.

Think about it, people in the United States are already extravagant enough to start shooting movies with 3D technology, but optical laboratories in other countries around the world are still polishing lenses.

This can no longer be said to be a technical gap, it is entirely a conceptual gap!

And considering the current relationship between us and the United States, if we want to import this kind of 3D imaging equipment from the United States, it is estimated that the Americans will definitely not want to sell it.

Especially if you let them know that when you import such equipment, you also want to manufacture surgical robots.

To know the status of this Da Vinci surgical robot in the medical industry, it is the same as Apple's status in the mobile phone industry.

It can be said that it is the only one in the world.

The capitalists in the United States rely on companies to sell equipment to make money every year, and they can also make a fortune in the stock market.

If we come up with a robot whose performance is similar to that of Da Vinci, or even better than him, do you think Americans will go crazy after seeing it?
