After the short Spring Festival holiday, the equipment department has ushered in a new round of development.
There is an endless stream of people coming for interviews every day, and the entire auxiliary building gradually becomes full.
Wang Dali held a straw in his mouth, drank soy milk, and burped as he walked into the office.
Sitting down in front of the computer, without taking off my coat, I heard the call from the leader.
"Dali, come here."
Lu Tingfeng stood at the door of the office and waved to Wang Dali, who was two meters away.
The seats of Wang Dali and Assistant Lu Tingfeng were separated by an aisle, on both sides of Lu Tingfeng's office.
This position is very important and can be easily summoned at any time, which demonstrates his status as the leader's confidant.
But it also led to frequent setbacks in his fishing plans. It can be said that every gain must come with a loss.
Wang Dali took a deep breath, swallowed the remaining half bag of soy milk, wiped his mouth, and ran forward quickly.
"How's the endoscopy project going?"
As soon as the two sat down in the office, Lu Tingfeng asked impatiently.
"There will be a lot of things after the new year, but the design and proofing are almost done. Certification will start next week."
“We have everything ready here, all we need is Kuwei’s CMOS chips.”
"I just contacted them last week and said they sent a few chip samples for testing. They should be able to arrive today."
"It seems everything is going according to plan." Lu Tingfeng nodded, turned on the computer screen projection, and said sincerely.
"Dali, the endoscopy project is not only important to the company, but also to you."
"Now that you have enough qualifications, if you do a good job on this project, you can lead one or two projects independently, and then you can be promoted to the position of vice president.
"By the way, these are a few new projects this year. The ultrasonic scalpel project is not too difficult, so I'll leave it to you. Let's see which of the others you are interested in? How about the biological scaffold?"
Wang Dali looked at the information on the screen curiously and was stunned for a moment.
"Artificial heart, artificial blood vessels, bionic microneedles, ultrasound scalpel, biological stents...head, you have so many projects!"
"These three projects before ultrasound surgery look so awesome, why don't you leave them to me?"
Lu Tingfeng glared at him: "I have to keep an eye on these three projects personally. Aren't you busy with the endoscopy project now? This project is very important, so you can't be distracted too much. I only decided to see you doing it smoothly. The ultrasonic surgery project will be assigned to you."
Wang Dali's eyes wandered over the two projects of "artificial heart" and "artificial blood vessels", and he was scratching his head and head anxiously.
"Boss, the artificial organ project is so awesome, so cutting-edge, and so high-tech. It suits me right away. 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 said thoughtfully: "The artificial organ project is difficult to do. Although we have recruited many new people, we still have to start from scratch and accumulate experience. It may take several years to complete. "
"As for the artificial blood vessel project, it's mainly done by the Nano Laboratory, 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 microneedles?"
Wang Dali stared at the information on the artificial heart, without blinking, and said firmly: "Boss, I just want to do the artificial heart project."
Lu Tingfeng was speechless at once: "Why are you like this? You talk about fishing every day, but when you turn around and see a difficult job, you take over it. Why don't you do an easier job for you?"
Wang Dali scratched his forehead in embarrassment: "Tou, why don't I know whether you are fishing or not?"
"Come on," Lu Tingfeng snorted coldly: "Your nickname of 'Fish King' has spread throughout the company, even the customers have heard about it. If our company didn't have an overtime culture, you would have been blacklisted long ago. I still want a ridiculous promotion and salary increase."
Wang Dali was stunned: "What? I actually have a nickname?"
"King of Fishing?" He repeated it several times and instantly beamed: "This nickname suits me so well. Brothers really understand me."
"Ahem~" Lu Tingfeng saw that Hua Feng was about to go off track, so he coughed twice and brought the topic back.
"Okay, then you have to put a name to the artificial heart project first, and then put the people and framework together."
"No problem." Wang Dali nodded. There were too many technical difficulties involved in the artificial heart, and it would take him some time to get started.
Lu Tingfeng pondered and said: "I'll leave the two projects of bionic microneedle and ultrasonic scalpel to you, and I'll leave the other projects to Qi Liang. Fortunately, color ultrasound, monitors, and defibrillators have each hired a manager, who can Share part of my work. Otherwise, there are too many product lines and I really can’t manage them.”
"It's a good thing that there are more and more product lines. It means that the development of equipment is getting better and better."
Wang Dali said with a playful smile: "Boss, if you are capable, please work harder. Apart from you, who else in the company can control this right now?"
Lu Tingfeng waved his hand and drove him out: "Okay, why don't you act serious all day long? Go to work quickly."
After working together for more than three years, he has already recognized Wang Dali's ability.
Wang Dali may look like an old man, he is lazy all day long and wants to fish when nothing happens.
But when something happens, he immediately becomes serious and becomes extremely reliable, never slipping up.
His 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 tough problem, he only thinks about conquering and challenging. He is really a rare technical talent.
Maybe capable people have more or less tempers. Fortunately, Wang Dali is just a bit lazy. As long as he learns how to stimulate the other party's enthusiasm, it will not be difficult to manage him.
Lu Tingfeng couldn't help but feel a little lucky when he thought of this.
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, could he cope with it.
If he had to follow the rough and simple management methods of his previous company, 80% of them would not work and would only have a counterproductive effect.
"I heard that the directors of those big experiments are all unruly geniuses, with eyes that reach to the top of their foreheads. They dislike everyone, and they do even more bizarre things."
"That Tang Que is not doing his job every day, squandering funds, buying random food and drinks, and selling them in the cafeteria. He is not afraid that the employees will suffer from something wrong. If it were another company, how could he be so wanton and reckless."
"Especially that Wen Renlong. I heard that when he was working in an external company, he would bang the table and yell at his boss every day, and he couldn't do anything about it."
"I don't know how it happened. When I came here, I was very obedient to Mr. Wei and told him not to go east or west."
"When it comes to managers, Mr. Wei is the master. I have to learn from him."
Lu Tingfeng looked out the window and fell into memories.
Wei Kang's every move, word and deed were constantly replayed in his mind.
He pondered the deep meaning and gradually became obsessed with thinking.
****
Wang Dali returned to his seat and carefully read the technical information on the ultrasonic scalpel.
Ultrasound scalpel is the most commonly used energy cutting instrument in surgical laparoscopic surgery, and it is inseparable from the thorax and abdominal cavity.
It has many structural similarities with rigid endoscopes. They are both composed of a host, a handle, a variety of handheld instruments and other accessories.
It's just that the ultrasonic scalpel has an extra blade. This metal blade can mechanically oscillate at an ultrasonic frequency of 5.5kHz to coagulate and denature human tissue to achieve the purpose of cutting and stopping bleeding.
The ultrasonic scalpel has a relatively low temperature, less bleeding, less damage to tissues, and faster postoperative recovery. There is no current passing through the human body when the blade is working, so it is safer. The surgical field of view is also very clear, without smoke and water vapor. white
Compared with electric scalpels and laser scalpels that emit smoke and smell like barbecue, the ultrasonic scalpel has an overwhelming advantage and 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 device was produced by Johnson & Johnson.
Until now, 90% of the entire market share is monopolized by Johnson & Johnson, and an ultrasonic bone knife has been sold in China for a high price of four to five thousand.
"This project comes at the right time. In general surgical operations, rigid endoscopes are used with ultrasonic scalpels. If we can provide both ultrasonic scalpels and endoscopes as a complete set, we will definitely be very competitive."
"It's just that this way, we have to run into the giant Johnson & Johnson again."
"Coupled with Olympus, we are attacked from both sides. There are tigers blocking the way in front of us and hungry wolves chasing after us."
"Only Sanqing has the strength to start a war with the monopoly giants in the two fields of ultrasound and endoscopy at the same time."
"The medical device market is really difficult to deal with. It's simply a road of constantly fighting monsters and upgrading. We have to knock down all the giants like Johnson & Johnson and Olympus before we can grab a bite."
Wang Dali shook his head and smiled bitterly as he thought.
However, as he watched, the expression on his face became solemn, and then slowly turned into shock.
"This key component of the ultrasonic scalpel, the transducer, 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 high energy density and a very short response time.”
"The most important thing is to maintain stable high power output with minimal energy loss in the entire process."
"Such a material is dozens or hundreds of times stronger than commonly used piezoelectric ceramics. It's really amazing."
“With such core components, Sanqing’s ultrasonic scalpel can not only be used with rigid endoscopes, but can even be used with flexible endoscopes.”
He stared at the computer screen, his mind racing, and he was very excited.
Suddenly, someone in the distance called his name.
"Dali, the chip from Kewei has arrived."
Wang Dali picked up the water glass on the table and drank it in one gulp, and then regained his composure.
He got up and walked towards the testing room. As soon as he entered, he saw the CMOS chip on the table.
There is a circle of engineers responsible for optics, mechanics, process and inspection.
He smiled and asked: "Xiao Du, have you seen the chip? How is the effect?"
Xiao Du, the engineer in charge of optics, nodded and said: "After a rough inspection, the pixels are quite high and meet our standards. As for the specific parameters, I will give them to you after testing later."
"Very good," Wang Dali clapped his hands excitedly and said, "Then what are you waiting for? Now that everything is ready, quickly assemble the endoscope sample."
"Okay." Everyone nodded and dispersed.
A few days later, three sets of endoscope samples were produced and preliminary debugging and verification began.
Rigid endoscope products are sleeve-specific and are much more complicated than capsule endoscopes.
The entire endoscope system has a variety of equipment, including handles, main units, light sources and accessories.
Among them, the handle is held by doctors and contains a CMOS imaging chip, which is responsible for adjusting the focus, collecting images, and then converting them into electrical signals to be transmitted to the host. It also controls a series of operations such as photography and video recording.
The host is used to process images and project the images onto the monitor, which is the core component of the entire device.
The light source is also easy to understand, because the human body is completely dark. If you want the doctor to see clearly the human tissue inside, you need to provide a certain brightness of light.
As for accessories, they include optical fibers, sleeves, etc.
Therefore, after the sample is assembled, it must go through a series of debugging to detect all problems as much as possible.
