To cut bone tissue smoothly, the amplitude of the blade needs to be at least 100 μm.

Wang Dali set the working frequency at 70kHz and controlled the knife head to cut the sheep's thigh bone.

This time, like cutting a cake, the thick leg bones were cut off with ease.

Wang Dali looked at the incision carefully. It was very smooth and fine, without any cracks or damage to the remaining meat on the bones. He couldn't help but be amazed.

"With this thing, who will use a kitchen knife to chop bones in the future?"

Xiao Du chuckled at the side: "Boss, you can use an ultrasonic knife to chop the bones, but it's not necessary. Isn't this an ultrasonic cannon to kill mosquitoes? It's too big a trivial matter."

"This is the power of technology." Wang Dali's eyes showed a trace of obsession, and he was filled with emotion.

"I'll try to increase the power and see what power can achieve the effect of crushing bones instantly."

He adjusted the frequency to 100kHz and 130kHz and tried it once. He found that the higher the frequency, the more bone tissue could be completely crushed in an instant.

However, due to excessive output power, the damage to other tissues is also greater.

Not only was the bone where it was cut completely shattered, but the marrow inside also melted into liquid and flowed out.

Wang Dali nodded and concluded: "It seems that for surgical operations, lower power must be used to achieve efficient bone cutting. Excessive output power will cause soft tissue damage."

"But it depends on the situation. Sometimes the bone tissue just needs to be cut off, and sometimes it needs to be crushed, which requires using different working frequencies."

"Our ultrasonic scalpel has great advantages. One is the extremely high utilization of the output power of the transducer. There is not much energy loss in the process. It uses 60W of power to complete the cutting effect that can only be achieved by 80W or 120W."

"The other is that the transducer itself is very precise. Johnson & Johnson's ultrasonic osteotome has a range of several hundred microns, but our ultrasonic scalpel has a range of less than 100 microns at the same power."

"In this way, not only will it not cause fragmentation and damage to adjacent tissues, but the cutting will be more precise, and it can even cut capillaries and nerve fibers and stop bleeding."

"The size of cells in the human body is basically on the micron level, the diameters of veins and arteries are on the millimeter level, and capillaries and nerve fibers are below 100 microns, so only our ultrasonic scalpel can operate on this scale."

"Johnson & Johnson's ultrasonic scalpel can only stop bleeding and coagulate veins and arteries, and its accuracy is completely inferior to ours."

"Okay, having said all that, this meat cannot be wasted. It's time to conduct the final experiment."

Wang Dali kept talking for a long time, and finally licked his tongue, his eyes shining with green light.

"The barbecue feast has begun."

The crowd instantly burst into cheers.

"Boss, I've been waiting for your words."

"I'm going to get some bottles of Coke."

"Boss, you must be tired after testing for so long. Let me barbecue."

"Then it's up to you." Wang Dali waved his hand and sat down on the chair next to the table.

Xiao Du took the lead and adjusted the output power to the maximum.

Then he took the ultrasonic knife and tore the pieces of meat into pieces, put them on plates and distributed them to everyone.

Soon, everyone smelled an unusually delicious aroma of barbecue.

During this process, the mechanical energy of the ultrasonic scalpel quickly destroys the proteins in the muscle tissue, causing it to coagulate and denature.

At the same time, a thermal effect is produced, and the entire piece of meat is cooked from the outside to the inside.

However, due to the relatively low thermal effect, the temperature generally does not exceed 80°C.

In this way, there is no oil smoke, no blackening, the meat is fresh and tender, the flavor is retained, and the taste is very delicious.

“It’s so delicious. The low-temperature grilled texture is really unique and rare.”

Wang Dali swallowed a piece of plump mutton and sighed in admiration.

Everyone else was busy grilling the meat, and after it was done, they ate hard.

There was sudden silence in the entire testing room.

All that was left was the sound of chewing, slurping, and slurping drinks.

Wang Dali was the first to eat and drink enough. He spread out his limbs, half-lying on the chair, and burped comfortably, feeling that a good life is nothing more than this.

"While eating barbecue and doing experiments, I finished the product and beat the competition."

"This is the beautiful life of a technology tycoon."

"Hahaha~" He couldn't help grinning and grinning.

"Is it really so delicious? Can I try it?" someone behind asked.

"Of course, you can do it yourself. Why, you want me to feed it to your mouth?"

Wang Dali waved his hand lazily, and suddenly felt that the voice asking the question was extremely familiar. When he turned around to look, he was instantly frightened and jumped up from his chair.

Lu Tingfeng was seen standing behind him with a straight face.

The people next to him were so frightened that they fell into silence. They all lowered their heads and remained silent.

Lu Tingfeng's eyes flashed with two cold gleams, and he shouted loudly: "Look at you, a perfectly good test room has been turned into a mess like this. It's just nonsense. What do you mean?"

Wang Dali looked sad, said nothing, and allowed the leader to scold him.

He knew that he had gone too far this time. It would be okay if he didn't get caught, but he would have to admit that he was unlucky if he did.

Lu Tingfeng's output was as fierce as a tiger's. After scolding him, he felt a little tired. He smelled the aroma of meat in the room and his nose moved involuntarily.

After looking at the tender roasted mutton on the plate, I couldn't help but reach out with my right hand, grab a piece and stuff it into my mouth.

After swallowing a mouthful of mutton, the delicious taste rushed straight to my forehead.

He was silent for a moment, and it took him a long time to say: "Forget it this time, I won't do it next time."
