Chapter 268 If you want to do it, do it high-end

    Medical gas turbine, also known as dental gas turbine handpiece, is an advanced dental medical device.

    As the old saying goes, toothache is not a disease, it hurts really badly. Therefore, dentistry is a very important medical category in various countries, and many dental treatments require drilling and grinding the outer shell of enamel and dentin.  In order to expose the dental pulp or necrotic tissue where the disease occurred, it can be easily removed or treated with drugs.

    Teeth are the hardest part of the human body, and traditional methods cannot achieve the purpose of drilling and grinding teeth. Therefore, medical equipment specially used for drilling and grinding teeth has emerged.

    The early ones were purely mechanical. The doctor stepped on the pedal with his feet while using the rotating head to treat the patient. Since the rotation speed was only a pitiful few thousand turns, the efficiency was slow, and the patient was also extremely painful during the treatment process.  .

    Later, with the emergence of motors, the traditional mechanical drill bits were replaced by micro electric drill bits, and the rotational speed also increased from the original several thousand to tens of thousands of revolutions.

    However, due to the inherent shortcomings of the electric motor, the lubrication and water spray cooling devices cannot be integrated into the drill bit, and dentists are often in a hurry during treatment.

    Because of this, Western countries developed a new type of dental drilling and grinding instrument in the late 1950s, which is the air turbine. The principle is very simple. It uses compressed air to drive a micro-turbine to rotate, thereby achieving 300,000 per minute.  Turn above the highway.

    At the same time, because of its purely mechanical mechanism, it is easy to integrate a water spray cooling device inside, so that the teeth can be drilled and ground while the patient's mouth is cooled and cleaned with water, thereby reducing the patient's pain.

    The principle is very simple, but it is very difficult to make it. Everything else is easy to handle, but the difficulty lies in the micro turbine called the movement inside.

    Not only is it made small and exquisite, but the weight is strictly limited within a certain range. That's it. The key is that the centrifugal force generated by hundreds of thousands of revolutions per minute is quite terrifying. Ordinary materials may not reach the target.  Torn apart by powerful centrifugal force.

    In addition, processing accuracy, overall airtightness, and specialized testing equipment all require very high requirements, resulting in ordinary companies not being able to do it even if they want to.

    Because of this, once the gas turbine came out, it was monopolized by a few Western companies. Let alone the blank in the country, most medical device manufacturers have never even heard of it.

    It¡¯s just that this kind of high-performance turbine movement is a huge hurdle for domestic medical device factories, and even very difficult for some ordinary precision manufacturing factories, but it is not a problem for Tengfei Factory.

    No matter how complicated this turbine is, is it more complicated than the turbine in a jet engine?

    Not only does it have to withstand high temperatures, it also has to endure the torture of high pressure. As for the centrifugal force, each square centimeter has to withstand nearly five tons of tearing. The turbine in the gas turbine is just ordinary compressed air, and the working environment is simply not much better.

    As for materials, parameters, and transmission, they are more than one level lower than aeroengines. Otherwise, aeroengines would not be called the crown jewel of the industry.

    We have technology, materials, talents, and equipment. In addition, in order to save money in the past two years, Master Ju and others have been using watch processing equipment to make miniature testing machines with a diameter of 10 to 20 centimeters to conduct theoretical feasibility studies.  , which gives the factory the ability to process micro-components.

    Everything is ready, and all that is needed is a product to integrate it and monetize it. Zhuang Jianye, who was tortured by toothache in his previous life, decided to make high-end products. Medical devices are not only high-end, but also extremely profitable.

    The key is that the entry threshold is high. Once a word-of-mouth effect is formed, it is easy to form a monopoly. Counting money will make your hands cramp, and the company is not yet transparent. It is in line with the corporate philosophy of Tengfei Factory to make a fortune in a low-key manner.

    As for the so-called bladeless fan, it is a trap. You may make a small fortune at first. The problem is the harsh intellectual property environment in China. Within two years, this thing will be everywhere.

    By then, the best outcome for Tengfei Factory is to share the market equally with a few giants. If there is a slight mistake, it may become like that poor VCD invention factory and close down hastily.

    The jet power office is a long-term job. Making quick money can only solve temporary needs. But compared to the entire jet power research and development, it is better to find a long-term, stable and profitable business.

    Gas turbines are very good. Companies like the 517 Factory want to do it but can't. The large aircraft engine factories in this system have the technology but look down on such a child. Such a huge market is so empty. I'm sorry if Zhuang Jianye doesn't pick it up.  own conscience.

    So Zhuang Jianye generously disclosed all the bladeless fans. It was just a gimmick to attract people's attention and attract attention.If you do enough, its mission will be accomplished, leaving the gas turbine as the real star.

    Because he believes that at this exhibition jointly organized by several ministries and commissions, the leaders of the health system, like the heads of other systems, will definitely participate. Even if there are no medical devices they want to participate in the exhibition, they can support them in order to support the call from their superiors.  Given the arduous development of national defense and military industry enterprises, the health system would still dig into their pockets to buy some televisions, refrigerators, electric fans, quilt covers, bedsheets and the like.

    What would happen if among these inconsistent light industrial products suddenly there is a medical device that the medical system needs to import in large quantities every year?

    It is obvious that the effect is surprisingly good.

    The old man who exclaimed put the gas turbine in his hand and looked at it to the left and then again. Not counting that, he also asked Zhuang Jianye and Master Ju to connect the equipment and give it a try. Then his serious face finally appeared.  A smile: "Well Judging from the feel, it is no worse than foreign products."

    By this time, Zhuang Jianye had already learned the identity of the old man from the ministry cadres of the aviation system. Sure enough, he was the leader of the health system. His name was Hong Xiaosong. He was transferred to the health department from the Union Hospital in Beijing last year.

    Not only is he an upright person, but he also has superb medical skills, especially in otolaryngology, and is one of the top experts in the country. Therefore, Hong Xiaosong is no stranger to dentistry and is even more proficient than ordinary experts.

    After learning about the situation, Zhuang Jianye immediately explained something to Master Ju. Soon Master Ju brought two hard-boiled eggs. Zhuang Jianye quickly received them and walked to Hong Xiaosong, who was carefully inspecting the gas turbine. He smiled.  He said: "Dr. Hong, I heard that skilled doctors abroad can engrave words on eggs. You are also an expert in this field. Can you also mention one on eggs for us?"

    As he spoke, he handed over the two boiled eggs as if they were a treasure.

    Originally, Hong Xiaosong was very happy to see domestically produced medical equipment here. He couldn't bear to put it down when he got it. Now when he heard this, he scratched his own itch. He nodded without thinking: "Okay!"
