"The samples have been tested and performed well in all aspects."
In the conference room, engineers reported the test results of samples.
“Especially for CMOS chips, HiSilicon uses 3D stacking technology to design image sensors, which greatly improves the dynamic range and noise performance. At the same time, the heat resistance is also improved. The overall performance is very outstanding and meets our requirements for high-end endoscopes. Camera capability requirements.”
"The software still needs to be continuously optimized to achieve the integration of software and hardware and maximize the functionality of the hardware."
"Is there any problem?" Wang Dali asked directly.
The optical engineer hesitated for a moment and then said: "According to reports from Kewei, the yield rate of CMOS chips is relatively low, currently only 50%. As a result, the cost is much higher than expected, and the price will almost double."
"What's the reason for the disqualification?"
"It is said that there is a problem with heat dissipation. The temperature is a bit high after being used for a long time, and it cannot meet our standards."
Wang Dali suddenly had a headache. Yield rate and heat dissipation were hurdles that chip manufacturers could not get around. Even companies as strong as Qualcomm and Intel would fall over 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 we lower the test requirements, wouldn't we be able to increase the yield and reduce the cost?"
Wang Dali shook his head: "No, isn't this a loss of your own brand? Besides, medical equipment is not a mobile phone. If the temperature is too high, you can take a break. If something goes wrong when the doctor is performing an operation, you ask him to wait for half an hour before performing the operation. ?”
Everyone was immediately speechless.
Wang Dali pondered for a moment and said: "As for the yield rate, we still need to continue to improve the craftsmanship, and also see if there is any improvement in the design."
"Our standards are indeed very high because we are competing against international giants such as Olympus. Otherwise, how can we compete with them?"
"However, although the standards cannot be lowered, we can also find ways to optimize them."
"Let's see, for chips that don't meet the standards but are fine, we reduce the performance of the CMOS chips and use them in mid- to low-end products. This way we can effectively reduce power consumption and the temperature will naturally go down."
"Then the software should be optimized and controlled well so that there are no problems. Anyway, for mid- to low-end products, doctors' image requirements are not too high and there is no need for 4K imaging."
Everyone nodded: "A good idea. This can greatly improve the chip utilization rate, and the cost is acceptable."
"In this way, the chip yield rate can reach 80%, which is enough for large-scale mass production and commercial use."
"It can't be perfect, but this is also a feasible solution."
Wang Dali clapped his hands and said: "When we go back to trial production, we need to send people to Kewei to keep an eye on it to see if there is room for improvement."
"Okay, what step has been detected during registration?"
"Since this is a Class II medical device, the registration process is relatively fast. It is estimated that the registration certificate will be obtained in another month."
Wang Dali nodded: "Okay, let's wait and optimize the software during this period."
Suddenly someone asked: "Boss, has the price of our rigid endoscope been released?"
Wang Dali operated the computer and said without raising his head: "Not yet, but it will definitely be cheaper than Olympus, probably in the hundreds of thousands."
"This is not something you should worry about. What I am going to say next is what you should pay attention to."
While speaking, he had already projected a ppt on the big screen.
"Is this an ultrasound scalpel?"
Waves of exclamations sounded in the conference room.
Wang Dali pressed his hands in vain, and everyone immediately fell silent. Everyone looked at him intently, waiting for detailed explanations.
"I have thought carefully about it. Although Kewei has been able to develop its own CMOS chips, it cannot surpass Sony in terms of performance. In this way, apart from selling the products cheaper, we cannot distance ourselves too much from Olympus."
"You know, if we can reduce prices, Olympus can also reduce prices. The price gap cannot form a stable competitive advantage at all."
"Fortunately, my leader gave me the ultrasonic surgery project, so I had a new idea."
“Isn’t there a whole range of solutions that are in vogue these days?”
"We already have capsule endoscopes and rigid tube endoscopes. We can integrate all the equipment required for minimally invasive surgery and provide them to customers. This will greatly improve our competitiveness."
"You must know that although these equipment giants have a monopoly in a certain aspect, they only specialize in one field and are not comprehensive enough to provide an overall solution like ours."
Everyone showed expressions of sudden realization and exclaimed:
"Boss, you are so awesome. This is such a genius idea."
"As expected of a technology leader, he has a high level of vision and a high level of vision!"
"Why didn't I think of that?"
Wang Dali coughed and said, "Okay, seriously, let's discuss it and see what equipment is missing if we want to give a complete set of plans."
Everyone started discussing it.
"For minimally invasive surgery, in addition to endoscopes, do you need various scalpels, electrosurgical scalpels, ultrasonic scalpels, etc."
"Do you need an anesthesia machine, a ventilator, and an infusion pump?"
"You missed two things, namely the operating bed and the operating light."
"Uh, no, the technical content is too low. We don't need to do this."
"The company should focus on making high-tech equipment."
"I agree. Those with low technical content should not compete with other domestic manufacturers. We should always leave a mouthful of soup for others."
"Yeah, if you want to tighten the screws, go ahead and don't pull me in."
"Okay, okay, the more you talk, the more outrageous it becomes." Wang Dali knocked on the table and said dissatisfied: "What's going on here, even the operating table and operating light are out."
He emphasized word by word: "We are a high-tech integrated solution for minimally invasive surgery, not the entire operating room!"
"For minimally invasive surgery, a rigid endoscope is not enough. You also need a flexible endoscope, a pneumoperitoneum machine and an ultrasound scalpel."
"Insufficiency machines and ultrasonic scalpels are used together with endoscopes. They must be made first. They can be used as a set and can also promote the sales of endoscopes."
“The insufflator machine is relatively simple, and it is a Class II medical device, so the certification time is very fast.”
"Ultrasonic surgery is more difficult, so it is also our next tough project."
"There are mainly two key points, one is the transducer and the other is the cutter head."
"The vibration frequency of the cutter head is very fast. If the design is not good, it will easily resonate 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. "
"The technical difficulty lies mainly in the transducer. Its quality directly determines the performance of the device, and is also related to the surgical effect of cutting, hemostasis and blood vessel coagulation."
"There are two options for ultrasonic transducers, one is to use magnetostrictive material of nickel-iron alloy, and the other is to use piezoelectric ceramics like color ultrasound."
"But we have a better solution, which is to use giant magnetostrictive materials made of rare earth alloys to create high-power, ultra-high frequency, and ultra-high sensitivity transducers."
"With such core components, we can create high-power ultrasonic scalpels with good stability and high reliability, forming an absolute technical advantage."
"The two key equipments of endoscope and ultrasonic scalpel are our own core technologies. Are we still worried that we can't beat our competitors?"
"You know, the endoscope is from Olympus and the ultrasound scalpel is from Johnson & Johnson. They each do their own thing. They can't join forces at the moment. Naturally they are no match for us."
At this time, someone asked timidly: "What about the electric knife?"
Wang Dali waved his hand and said: "There is no need for an electric knife, we have an ultrasonic knife, which is enough."
"As we all know, ultrasonic scalpel can definitely beat electrosurgical surgery in terms of reducing surgical blood loss and clearing the field of view. Now even orthopedics are gradually giving up electrosurgical surgery and starting to use ultrasonic osteotome."
"It's just that in current ultrasonic scalpels, the transducer and the blade must be rigidly connected directly, and the length cannot be too long, otherwise the mechanical energy will not meet the surgical requirements due to excessive loss."
"This also limits the application of ultrasonic scalpel to minimally invasive surgeries under rigid tube endoscopes, and cannot be directly used in digestive endoscopic surgeries guided by flexible endoscopes."
"Currently, high-frequency electrosurgery is mainly used for digestive endoscopy, but high-frequency electrosurgery causes severe thermal damage during the operation, making it difficult to control the cutting and coagulation effect, and the patient's recovery time is long."
"None of this is a problem with our ultrasound scalpels."
"Our ultrasonic scalpel has high power and high energy conversion rate, so the blade can be connected using a soft connection method, and the connection length is also greatly increased. In this way, it can be used in digestive endoscopic surgery instead of the electrosurgical scalpel, which greatly improves the efficiency of the operation. The effect of surgery.”
"Thanks to us, surgeons will be able to conquer the world with an ultrasonic scalpel in the future, hahaha."
This remark instantly caused the whole room to laugh.
The engineers were all very excited and had a strong interest in the ultrasonic scalpel project and started a heated discussion.
"Awesome, fucking Olympus and Johnson at the same time!"
"The ultrasonic scalpel can also be used with a hose. Johnson & Johnson will definitely not be able to withstand this cut."
"Such a centralized solution is very suitable for single-port endoscopic surgery."
"Should we also design a single-hole surgical connector?"
"It's a good idea. It would be better to make some optimizations in the design to make it more suitable for doctors to operate with both hands."
“I can’t wait to make a full set of laparoscopic surgery solutions, and then take the samples to doctors to try them out.”
Wang Dali nodded secretly while listening: "Don't tell me, these guys have pretty good ideas. They have a lot of good ideas. I have to write them down quickly."
His fingers were flicking on the computer, recording everyone's thoughts, summarizing them into a report and submitting it.
This "Feasibility Study Report on the Integrated Minimally Invasive Surgery Solution" quickly arrived in Wei Kang's hands.
After Wei Kang saw it, he couldn't help but applaud.
"Wang Dali is a talented person. He has his own ideas. His view of things is not limited to local details, but from a high-level view, from point to point. He has a good overall view, which can be well cultivated."
"It seems that we can rest assured that the ultrasonic surgery project will be left to him."
"As for the pneumoperitoneum machine and flexible endoscope projects, let's follow 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 take charge of his own role, my life will be much easier."
Wei Kang thought happily, and immediately signed the agreement, letting Wang Dali go and do it.
