I can extract side effects

After the short Spring Festival holiday, the equipment department ushered in a new round of development.

There is an endless stream of people who come to interview every day, and the entire annex building gradually becomes full.

With a straw in his mouth, Wang Dali walked into the office while drinking soy milk and hiccupping.

Sitting down in front of the computer without taking off his coat, he heard the call from the leader.

"Dali, come here."

Lu Tingfeng stood at the door of the office, waving to Wang Dali who was two meters away.

The seats of Wang Dali and Lu Tingfeng's assistant happened to be separated by an aisle, and they were arranged on both sides of Lu Tingfeng's office.

This position is very important, and it is very convenient to be called at any time, which demonstrates his status as the leader's confidant and beloved general.

But it also caused his fishing plan to be frustrated from time to time. It can be said that there are gains and losses.

Wang Dali took a sharp breath, swallowed the remaining half bag of soy milk in one gulp, wiped his mouth, and ran forward quickly.

"How's the endoscopy project going?"

As soon as the two of them sat down in the office, Lu Tingfeng couldn't wait to ask.

"There are a lot of things after the year, but the design and proofing are almost done, and the certification will start next week."

"We have everything ready here, the only thing missing is the CMOS chip of Kewei."

"I just contacted them last week and said that a few chip samples were sent for testing, and they should arrive today."

"It seems that everything is in the plan." Lu Tingfeng nodded, turned on the computer to cast the screen, and said earnestly.

"Dali, the endoscopy project is not only important to the company, but also to you."

"You have enough qualifications now, this project is done well, and if you lead one or two projects independently, you can be promoted to a vice president.

"By the way, these are several new projects this year. The ultrasonic scalpel project is not too difficult, so I leave it to you. Let's see who you are interested in? How about the biological scaffold?"

Wang Dali looked at the information on the projection screen curiously, and was instantly stunned.

"Artificial heart, artificial blood vessel, bionic microneedle, ultrasonic knife, bio-stent... Head, you have enough projects!"

"The three items in front of the ultrasonic knife look so awesome, why don't you give them to me?"

Lu Tingfeng glared at him: "I have to watch these three projects personally. Aren't you busy with the endoscopy project now? This project is very important, so don't be distracted too much. I only see that you are doing well. The Ultrasound Knife project is for you."

Wang Dali turned his eyes around the two items of "artificial heart" and "artificial blood vessel", scratching his head and ears in a moment of anxiety.

"Head, the artificial organ project is so awesome, cutting-edge, and high-tech. It suits me at first glance. You have a bad heart, so you can't be too tired. Why don't you leave this hard work to me to share your worries?"

Lu Tingfeng did not refuse this time, but mused and said: "The artificial organ project is not easy to do. Although we have recruited a lot of new people, we still have to explore from the beginning and accumulate experience. It may take several years to complete. "

"As for the artificial blood vessel project, it's mainly done by the nanolab, so don't even think about it."

"You'd better choose two easier projects first, and then get promoted. Artificial heart is too difficult, so it's not a good choice."

"Well, how about I give you the bionic microneedle?"

Wang Dali stared at the information on the artificial heart, without blinking his eyes, and said firmly, "Head, I just want to do the artificial heart project."

Lu Tingfeng was speechless for a moment: "Why are you like this? You usually say you want to fish every day, but when you turn around and see difficult jobs, you take care of them all. Why don't you do the easier jobs?"

Wang Dali scratched his forehead in embarrassment: "Head, why don't I know if I'm fishing or not?"

"Come on," Lu Tingfeng snorted coldly: "Your nickname of 'Moyu King' has spread all over the company, even customers have heard of it. If our company didn't have that overtime culture, you would have been blacklisted a long time ago. Still want a promotion and a salary increase."

Wang Dali was stunned: "What? I actually have a nickname?"

"Moyu King?" He repeated it several times, and smiled instantly: "This nickname is very suitable for me, brothers really understand me."

"Ahem~" Lu Tingfeng saw that the painting style was about to go off track, so he coughed lightly twice to bring the topic back.

"That's all right, you need to name the artificial heart project first, and then you can talk about the personnel and the framework."

"No problem." Wang Dali nodded. The artificial heart involves too many technical difficulties, and it will take him a while to get started.

Lu Tingfeng pondered and said: "The two projects of bionic microneedle and ultrasonic knife are entrusted to you, and I will entrust the other projects to Qi Liang. Fortunately, the projects of color ultrasound, monitor, and defibrillator have each recruited a manager. Share part of my work. Otherwise, there are too many product lines, and I really can’t manage it.”

"It is a good thing that there are more and more product lines, which shows that the development of equipment is getting better and better."

Wang Dali said with a playful smile: "Boss, you can do more work if you can. At present, besides you, who else can control the company."

Lu Tingfeng waved his hand and drove him out: "Okay, why haven't you been serious all day long, go to work quickly."

After working together for more than three years, he has already recognized Wang Dali's ability very much.

Wang Dali may seem like an old fritter, lazy all day long, looking like he wants to fish when he has nothing to do.

But when something happened, he immediately became serious, became extremely reliable, and never lost the chain.

The technical level is also very good. What is especially rare is that he has an unusual enthusiasm for any technical problem. When he encounters a hard bone, his mind is full of conquest and challenge. He is really a rare technical talent.

Maybe people with skills are more or less tempered. Fortunately, Wang Dali is just a little lazy. As long as he learns how to arouse the enthusiasm of the other party, it is not difficult to manage.

Thinking of this, Lu Tingfeng couldn't help but feel a little lucky.

Fortunately, he learned a lot of management skills from Mr. Wei. Only by focusing on the big and letting go of the small, and giving technical talents a relaxed atmosphere can they cope.

If he followed the rough and simple management method of his previous company, it would probably not work, and would only play a counterproductive role.

"I heard that the directors of those big experiments are all rebellious geniuses, the kind with eyes that grow to the top of their foreheads, and they don't like anyone, and the things they do are even more bizarre."

"That Tang Que doesn't do his job properly every day, wastes money, makes messy food and drinks, and sells them in the cafeteria. He is not afraid that the employees will make something wrong with them. If he changed to another company, how could he be so reckless."

"Especially that Wenrenlong, I heard that when he was in an outside company, he slapped the table with the boss and scolded him every day, and he couldn't control him at all."

"I don't know why, but when I came here, I was obedient to Mr. Wei, telling him to go east and dare not go west."

"As for the manager, Mr. Wei is a master. I have to learn."

Lu Tingfeng looked out the window, lost in memory.

Wei Kang's every move, every word and deed, played back in his mind constantly.

He pondered the deep meaning of it, and gradually became crazy.

*****

Wang Dali returned to his seat and carefully read the technical information of the ultrasonic knife.

The ultrasonic scalpel is the most commonly used energy cutting instrument in laparoscopic surgery, and it is inseparable from the chest and abdomen.

It has many similarities with the rigid tube endoscope in structure, and it is composed of a host, a handle, a variety of hand-held instruments and other accessories.

It’s just that the ultrasonic knife has an extra head, which can mechanically vibrate at an ultrasonic frequency of 5.5kHz to coagulate and denature human tissue to achieve the purpose of cutting and stopping bleeding.

The temperature of the ultrasonic scalpel is relatively low, less bleeding, less tissue damage, quick postoperative recovery, and no current passes through the human body when the scalpel is working, which is relatively safe, and the surgical field of view is also very clear, without smoke and water vapor. white

Compared with electric knife and laser knife with smoke and smell of barbecue, ultrasonic knife has an overwhelming advantage, and it is called a bloodless scalpel.

It can be said that apart from the high price, there are almost no disadvantages.

In the 1990s, the world's first clinically used ultrasonic scalpel equipment was produced by Johnson \u0026 Johnson.

Up to now, 90% of the entire market has been monopolized by Johnson \u0026 Johnson, and an ultrasonic bone knife has been sold at a high price of four to five thousand in China.

"This project comes at the right time. In general surgical operations, the rigid tube endoscope must be used with the ultrasonic scalpel. If we can provide the ultrasonic scalpel and endoscope at the same time, it will definitely be very competitive."

"It's just that in this way, we will bump into the giant Johnson \u0026 Johnson again."

"Combined with Olympus, it is like facing enemies on both sides. There are fierce tigers blocking the way in front, and hungry wolves chasing after them."

"At the same time, Sanqing has the strength to fight against the monopoly giants in the two fields of ultrasonic scalpel and endoscopy."

"The medical device market is really difficult to mix. It is simply a road of non-stop fighting monsters and upgrading. Only by knocking down giants like Johnson \u0026 Johnson and Olympus can we grab a bite of food."

Wang Dali shook his head and smiled wryly while thinking.

However, looking at it, the expression on his face became serious, and then slowly turned into shock.

"The transducer, the key component of the ultrasonic knife, actually uses a giant magnetostrictive material, which has a huge kinetic energy conversion rate."

"Not only can it withstand high temperatures, but it also has a high energy density and a very short response time."

"The most important thing is that it can maintain a stable high power output, and the energy loss in the whole process is extremely small."

"This kind of material is tens or hundreds of times stronger than commonly used piezoelectric ceramics, which is really amazing."

"With such a core component, Sanqing's ultrasonic scalpel can not only be used with rigid tube endoscopes, but can even be used with flexible tube endoscopes."

He stared at the computer screen, his mind was running fast, and he was very excited.

Suddenly, someone in the distance called his name.

"Dali, Kewei's chip has arrived."

Wang Dali picked up the water glass on the table and gulped it down in one gulp, only then regained his composure.

He got up and walked towards the testing room, and as soon as he entered, he saw the CMOS chip on the table.

Surrounded by a circle of engineers responsible for optics, mechanics, technology and testing.

He smiled and asked, "Xiao Du, have you seen the chip? How is the effect?"

Xiao Du is the engineer in charge of optics. He nodded and said: "I probably checked it, and the pixels are quite high, meeting our standards. As for the specific parameters, I will give you the test later."

"Very good," Wang Dali clapped his hands excitedly, and said, "Then what are you waiting for, since everything is ready, quickly assemble the endoscope sample."

"Okay." Everyone nodded and dispersed.

A few days later, the endoscope made three sets of samples, and the preliminary debugging and verification began.

Rigid tube endoscopy products are set-based, which is much more complicated than capsule endoscopy.

The entire endoscope system has a variety of equipment, including handles, hosts, light sources and accessories.

Among them, the handle is used by the doctor in his hand. There is a CMOS imaging chip inside, which is responsible for focusing, collecting images, and then converting them into electrical signals and sending them to the host. At the same time, it controls a series of operations such as photographing and video recording.

The host computer is used to process the image and project the picture onto the monitor, which is the core component of the whole set of equipment.

The light source is also easy to understand, because the human body is pitch-black, and it is necessary to provide a certain brightness of light in order for the doctor to see the human tissue inside.

As for accessories, it includes optical fiber, sleeve and so on.

Therefore, after the sample is assembled, it needs to go through a series of debugging in order to detect all the problems as much as possible.
