Chapter 481 Minimally Invasive Surgery Integration Program
"The sample has been tested and performed well in all aspects."

In the conference room, engineers reported the test results of the samples.

"Especially for CMOS chips, HiSilicon used 3D stacking technology to design image sensors, which greatly improved the dynamic range and noise performance, and also improved heat resistance. The overall performance is very outstanding, which meets our high-end endoscope requirements. Camera capability requirements."

"The software still needs to be further optimized in order to achieve the state of integration of software and hardware, and to maximize the functions of the hardware."

"Is there any question?" Wang Dali asked directly.

The optical engineer hesitated for a moment, and said, "According to Kewei's report, the yield rate of CMOS chips is relatively low, only 50% at present, so the cost is much higher than estimated, and the price will almost double."

"What is the reason for the failure?"

"It is said that there is a problem with heat dissipation, and the temperature is a bit high after a long time of use, which cannot meet our standards."

Wang Dali suddenly became dizzy. Yield rate and heat dissipation are hurdles that chip manufacturers cannot get around. Even if they are as strong as Qualcomm and Intel, they will overturn from time to time, let alone an entry-level player like Kewei.

Another engineer interjected: "As long as it's not a bad film, it doesn't matter. If you lower the test requirements, won't you be able to increase the yield and reduce the cost?"

"You know, the endoscope is from Olympus, and the ultrasonic scalpel is from Johnson & Johnson. They each do their own thing, and they can't join hands for a while. Naturally, they are not our opponents."

"As we all know, the ultrasonic knife is absolutely superior to the electric knife in terms of reducing blood loss and clear vision. Now even the orthopedic department is gradually abandoning the electric knife and starting to use the ultrasonic bone knife."

He kept flying his fingers on the computer, recorded everyone's thoughts, collected them into a report and submitted it.

"Both the insufflation machine and the ultrasonic scalpel are used in conjunction with the endoscope, and they must be made first, so they can be used as a set, and at the same time can promote the sales of endoscopes."

"Do you need anesthesia machines, ventilators, and infusion pumps?"

"Uh, no way, the technical content is too low, we don't need to do this."

"Okay, okay, the more you say it, the more outrageous it becomes." Wang Dali knocked on the table and said dissatisfiedly, "Where is this going? Even the operating table and operating lamp came out."

The engineers were all elated, and they had a strong interest in the project of the ultrasonic knife, and they discussed it enthusiastically.

"I can't wait to make a complete set of endoscopic surgery solutions, and then take the samples to the doctors for trial."

"Well, for chips that don't meet the standards but are okay, we reduce the performance of CMOS chips and use them in low-end products, so that power consumption can be effectively reduced, and the temperature will naturally drop."

Wang Dali pondered for a moment, then said: "In terms of the good product rate, we still need to continue to improve the craftsmanship, and at the same time see if there is any improvement in the design."

At this time, someone asked timidly, "What about the electric knife?"

Wang Dali coughed and said, "Okay, let's be serious, let's discuss it and see what equipment is still missing if we want to come up with a complete plan."

Wang Dali pressed his hands in vain, and everyone fell silent immediately, staring at him intently, waiting for the detailed explanation.

"There are mainly two key points, one is the transducer and the other is the cutter head."

"Our ultrasonic knife has high power and high energy conversion rate, so the knife head can be connected with a flexible connection, and the connection length is also greatly increased. In this way, it can be used in digestive endoscopic surgery instead of an electric knife, greatly improving The effect of surgery."

"For our Ultrasonic Knife, none of this is a problem."

"The ultrasonic knife is more difficult, so it is also our next tough project."

"It's a good idea. It's better to make some optimizations in the design, which is more suitable for doctors to operate with both hands."

"Wang Dali is a talent. He has his own ideas. He looks at things not limited to local details, but from a high-level perspective, from the point to the surface. He has a good overall view and can be well cultivated."

"The company should focus on making high-tech equipment."

Wang Dali shook his head: "No, isn't this branding yourself? Besides, medical equipment is not a mobile phone. You can take a break when the temperature is high. If the doctor has a problem during the operation, you ask him to wait for half an hour before performing the operation." ?”

"For minimally invasive surgery, it is not enough to have a rigid tube endoscope, but also a flexible tube endoscope, an insufflation machine and an ultrasonic scalpel."

"Thanks to us, surgeons can travel the world with an ultrasonic knife in the future, hahaha."

"Fortunately, the leader gave me the project of ultrasonic scalpel, so I have a new idea."

"There is no way to be perfect, and this is also a feasible solution."

"Then optimize the software and adjust it well, so that there are no problems. Anyway, for mid-to-low-end products, doctors don't have too high requirements for images, and they don't need 4K imaging."

"Our standards are really high, because we are targeting international giants like Olympus, otherwise how can we compete with them?"

This remark instantly elicited a burst of laughter.

"I have thought about it carefully. Although Kewei has been able to develop its own CMOS chip, it still cannot surpass Sony in terms of performance. In this way, we will not be able to distance ourselves from Olympus in addition to selling our products cheaper."

"Worthy of being a technical boss, with a high profile and high vision!"

"We already have capsule endoscopes and rigid tube endoscopes, which can completely integrate all the equipment required for minimally invasive surgery and provide them to customers, which will greatly improve our competitiveness."

Wang Dali nodded: "Okay, then just wait. During this time, optimize the software."

"You should know that although these equipment giants have a monopoly position in a certain aspect, they only specialize in one field, and they are not comprehensive enough to provide an overall solution like ours."

"Why can't I think of it?"

Suddenly someone asked: "Boss, has the price of our rigid tube endoscope come out?"

Wang Dali operated the computer and said without raising his head: "Not yet, but it must be cheaper than Olympus, probably hundreds of thousands."

"Awesome, fuck Olympus and Johnson & Johnson at the same time!"

He emphasized word by word: "We are a high-tech integrated solution for minimally invasive surgery, not to wipe out the entire operating room!"

"The two key devices, the endoscope and the ultrasonic knife, are our own core technologies. Are we afraid we won't be able to beat our competitors?"

Everyone showed a suddenly realized expression and exclaimed:
"Boss, you are so awesome, this is really a genius idea."

"For minimally invasive surgery, in addition to endoscopy, do you need all kinds of scalpels, electric scalpels, ultrasonic scalpels, etc."

The crowd was instantly speechless.

"Okay, which step did the registration detect?"

"Because this is a second-class medical device, the registration process is relatively fast, and it is estimated that the registration certificate will be obtained in another month."

"The ultrasonic scalpel that can also be used with hoses, Johnson & Johnson will definitely not be able to handle it."

The "Feasibility Study Report on the Integrated Program of Minimally Invasive Surgery" was soon in the hands of Wei Kang.

"Isn't there a whole set of solutions in vogue now?"

"It's just that in the current ultrasonic knife, the transducer and the knife head must be rigidly connected directly, and the length should not be too long, otherwise the mechanical energy will not meet the surgical requirements due to excessive loss."

"This is not something you should worry about. What I want to say next is what you should pay attention to."

Wang Dali clapped his hands and said: "When we go back to trial production, we should send someone to Kewei to watch and see if there is room for improvement."

"Is this an ultrasonic knife?"

"The technical difficulty is mainly on the transducer, which directly determines the performance of the equipment, and is also related to the surgical effect of cutting hemostasis and blood vessel coagulation."

Everyone chatted and discussed.

"Should we also design a single-hole surgical connector?"

"You still missed two things, that is, the operating table and the operating lamp."

"There are two options for ultrasonic transducers, one is to use nickel-iron alloy magnetostrictive materials, and the other is to use piezoelectric ceramics like color Doppler ultrasound."

"You know, if we can lower the price, Olympus can also lower the price. The price gap can't form a stable competitive advantage at all."

There were bursts of exclamations in the conference room.

"Currently, high-frequency electric knife is mainly used in digestive endoscopy, but the high-frequency electric knife has a large thermal damage during the operation, it is difficult to control the cutting and coagulation effect, and the recovery time of the patient is long."

"The insufflation machine is relatively simple, and it belongs to the second-class medical device, and the certification time is very fast."

Wang Dali waved his hand and said, "We don't need an electrosurgical knife. We only need an ultrasonic knife."

"The vibration frequency of the cutter head is very fast. If the design is not good, it will easily cause resonance and cause damage. However, the technology in this area is very mature in China. As long as you find a suitable high-end titanium alloy material and can achieve fine processing, there will be no problem. "

"In this way, the chip yield rate can reach 80%, which is enough for mass production and commercial use."

Wang Dali nodded secretly while listening: "Don't tell me, these boys have good ideas, and there are many good ideas, I have to write them down quickly."

"That's right, if you want to screw the screw, go ahead and don't pull me."

Everyone nodded: "Good way, this can greatly improve the utilization rate of the chip, and the cost is acceptable."

"Such a centralized solution is very suitable for single-hole laparoscopic surgery."

"However, although the standard cannot be lowered, we can also find ways to optimize it."

"I agree, don't compete with other domestic manufacturers for those with low technical content, and always leave a mouthful of soup for others."

"It seems that I can rest assured that the Ultrasonic Knife project is handed over to him."

"This also limits the main application of ultrasonic scalpel to minimally invasive surgery under rigid tube endoscope, and cannot be directly applied to digestive endoscopic surgery guided by flexible tube endoscope."

While speaking, he had already projected a ppt on the big screen.

"However, we have a better solution, which is to use giant magnetostrictive materials made of rare earth alloys, which can produce high-power, ultra-high-frequency, and ultra-high-sensitivity transducers."

After Wei Kang saw it, he couldn't help applauding it.

"With such a core component, we can manufacture a high-power ultrasonic knife with good stability and high reliability, forming an absolute technical advantage."

"As for the insufflation machine and the flexible endoscope project, let's do it according to his ideas."

"No wonder Lao Lu keeps praising him and wants to be promoted to vice president."

"Not bad, not bad, with such a general who can stand on his own, my life will be much easier."

Thinking happily, Wei Kang immediately signed the agreement and asked Wang Dali to let go.
