Chapter 268

Medical gas turbine, another name is dental gas turbine mobile phone, is an advanced dental medical device.

As the old saying goes, toothache is not a disease, but a fatal pain. Therefore, dentistry is a very important medical classification in many countries. In many dental treatments, the enamel and dentin shells need to be drilled and ground to expose the diseased pulp or necrotic tissue, so as to facilitate the removal or drug treatment.

But teeth are the most hard part of the human body, the traditional means can not achieve the purpose of drilling and grinding teeth, so the medical equipment specially used for drilling and grinding teeth came into being.

In the early stage, it was purely mechanical. While the doctor stepped on the pedal with his feet, he used the rotating head to treat the patient. Because the rotating speed was only a pitiful thousand revolutions, the efficiency was slow, and the patient was extremely painful in the process of treatment.

After that, with the emergence of the motor, the traditional mechanical drill was replaced by the micro electric drill, and the rotation speed increased from thousands of turns to tens of thousands of turns.

However, due to the inherent shortcomings of the motor, the lubrication and water cooling devices can not be inherited to the drill, and dentists are often in a hurry during treatment.

In the late 1950s, western countries developed a new type of dental drilling and grinding instrument, namely gas turbine. The principle is very simple, that is, using compressed air to drive a micro turbine to rotate, so as to achieve a high speed of more than 300000 revolutions per minute.

At the same time, because of its pure mechanical mechanism, it is easy to integrate the water spray cooling device inside, so that the patient's mouth can be cooled and cleaned with water while drilling and grinding teeth, so as to reduce the patient's pain.

The principle is very simple, but it's very difficult to do it. Everything else is easy to do. The difficulty lies in the micro turbine called movement.

It's not only small and exquisite, but also the weight is strictly limited within a certain range. That's all. The key is the centrifugal force produced by hundreds of thousands of revolutions per minute. It's quite terrible. Ordinary materials may be torn up by the powerful centrifugal force before they reach the target.

In addition, the processing accuracy, the overall airtightness and special testing equipment have high requirements, leading to ordinary enterprises even want to do, also can't do.

Because of this, once the gas turbine came out, it was monopolized by a few western enterprises. In China, let alone a blank, most medical device manufacturers had never heard of it.

However, this kind of high-performance turbine movement is a natural gap for domestic medical device manufacturers, and even is very difficult for some ordinary precision manufacturers, but it is not a problem for Tengfei factory.

No matter how complicated this turbine is, is it complicated by the turbine in the jet engine?

As for centrifugal force, each square centimeter has to bear nearly five tons of tearing. The turbine in the gas turbine is just ordinary compressed air, and the working environment is not too good.

As for materials, parameters and transmission, they are lower than aeroengine by more than one level, otherwise aeroengine would not be called the Pearl of the industrial crown.

There are technology, materials, talents and equipment. In addition, in order to save money in the past two years, master Ju and others have been using clock processing equipment to do theoretical feasibility studies on miniature testing machines with a diameter of 10 to 20 cm. In this way, the factory has the processing capacity of micro parts.

If everything is available, there is only one product to be integrated and realized. Zhuang Jianye, who suffered from toothache in his last life, has to be high-end. Medical devices are not only high-end, but also profiteering.

The key is that the entry threshold is high. Once the word-of-mouth effect is formed, it is easy to form a monopoly. If you count the money, you will get cramps. The enterprise is not obvious, and there is no water leakage. It is in line with Tengfei factory's corporate philosophy of low-key and making a big fortune.

As for the so-called leafless fan, TM is a pit. At the beginning, it may make a fortune. The problem is that the domestic environment for intellectual property rights is so bad that it will be everywhere in two years.

At that time, the best outcome of Tengfei factory is to share the market equally with several giants. If there is a little mistake, it may become the poor VCD invention factory and close down quickly.

Jet power office is a long-term job. Making fast money can only meet the needs of the moment. However, compared with the whole R & D of jet power, it is better to find a long-term, stable and profiteering business.

The gas turbine is very good. Enterprises like 517 plant want to do it, but they can't do it. Those large aviation development plants of this system have technology, but they can't see such pediatrics. Such a huge market is so empty. Zhuang Jianye is sorry for his conscience if he doesn't pick it up.

So Zhuang Jianye is very generous to make all the things that can be made public. That's a gimmick. It attracts people's attention and makes enough attention. Its mission is completed, and the remaining gas turbines are the real main ones.

Because he believes that at the fair jointly held by several ministries and commissions, the leaders of the health system, like those in charge of other systems, are bound to participate. Even if there are no medical devices they want, the health system will pay for some TV sets and electricity to support the development of the arduous National defense and military enterprises for the call of the higher authorities Refrigerator, fan, quilt cover, bed sheet and so on.What if a medical system suddenly needs a large number of imported medical devices in these uncertain light industrial products?

Obviously, the effect is surprisingly good.

The old man, who exclaimed in surprise, put the gas turbine in his hand. He looked left and then looked again. This was not enough. He asked Zhuang Jianye and master Ju to connect the equipment and try it. Then his serious face finally came up with a smile: "en In terms of hand feel, it's no worse than foreign products. "

By this time, Zhuang Jianye had learned the identity of the old man from the Ministry cadres of the aviation system. He was indeed the leader of the health system. His name was Hong Xiaosong. Last year, he was transferred from Union Medical College Hospital in Beijing to the head of the health department.

He is not only upright, but also skillful in medicine, especially in otolaryngology. He is one of the few experts in China. Therefore, Hong Xiaosong is no stranger to dentistry, and even more proficient than other experts.

After learning about the situation, Zhuang Jianye immediately explained to master Ju, and soon master Ju got two boiled eggs. Zhuang Jianye quickly took them and went to Hong Xiaosong, who was taking a gas turbine to examine them carefully. He said with a smile, "Dr. Hong, I heard that foreign doctors can carve characters on eggs. You are also an expert in this field, can you Give us one on the eggs, too. "

Then he handed over the two boiled eggs as if they were treasures.

Originally, Hong Xiaosong was very happy to see the domestic medical equipment here. He was reluctant to put it down when he got it. Now he scratched his itch and nodded his head without thinking about it
