Yan Feifan was very nervous on Saturday's schedule and he got up at five in the morning.

At nearly seven o'clock in the morning, I boarded the flight to Beijing.

I arrived at Baining Hospital just after 9:30 in the morning.

When he arrived at the hospital, Yan Feifan started the work of puncture and delivery of medicine for patients with terminal cancer.

There were four patients treated this time.

In addition to Researcher Zhang Run’s ex-wife and the performance teacher of the big star Zhao Yuxi, there is also a gastric cancer patient and a bowel cancer patient.

After 11 o'clock in the morning, Yan Feifan had lunch and discussed many matters about Yan Yu's company with Yu Youhai, Yu Youlian, Yu Youpeng, Zeng Ni, and Song Yi who participated through remote videos.

Now, in addition to the soaked beverage recipe that is further improved, Yanyu Medicinal Wine and Yanyu Food are both rapidly advancing.

Yanyu Food’s Binhai headquarters is under renovation, and General Manager Liu Zhe is inspecting chicken, duck and geese suppliers.

Yanyu Investment Company and Yanyu Medicinal Wine Company, which Yu Youpeng is responsible for, are busy with the procurement of various medicinal materials, and secondly, they are inspecting liquor suppliers.

According to Yu Youpeng, he is currently in contact with three small-scale breweries in Shandong Province.

The brewery is very proactive in the cooperation between the medicinal wines of both parties...

At twelve o'clock noon, Yan Feifan, Yu Youhai, Yu Youlian, Yu Youbin, and the technical director of the surgical robot gathered in the neurosurgery operating room to witness the first intra-spinal tumor puncture injection test operation of the surgical robot.

The subject of this operation was a 47-year-old man with the tumor located in the second and third thoracic vertebra.

His symptoms are already quite serious, and his spine is numb below the chest, which is compressed by a tumor, and he is not good at it.

In full view of everyone, it was the first experimental operation of the surgical robot. In order to avoid excessive tension in the patient, Baining Hospital gave him general anesthesia.

The patient was moved to the special surgical bed by the medical staff. After fixing, the surgical robot performed three-dimensional positioning of the surgical site.

Subsequently, the technicians performed the final preoperative examination of the surgical robot.

"Extraordinary, all the work is ready..."

Yu Youlian handed over the controller the size of a palm and said, "You press it in this historic moment!"

Yan Feifan shook his head and said, "I won't take this honor, I'll do it, let's do it for the technician!"

Yu Youlian did not continue to persuade him and gave the controller to the technical director Dong Gong, who was on the scene.

Gong Dong, who was in his forties, was a little excited, had rapid breathing, flushed on his face, and his hands were trembling and pressed the start button of the controller.

As the button was pressed, the surgical robot started to buzz. First, it was self-checked, and then all the movable bearings and surgical arms were rotated.

Immediately afterwards, the surgical robot was reset.

After pausing for five seconds, four special bone drills on the two surgical arms rotated at high speed and stabbed the second thoracic vertebra in different directions...

Yan Feifan must admit that machines that work according to established procedures are indeed very efficient.

There were eight vertebrae punctures in total, two waves, and it was completed within two minutes.

If Yan Feifan held a bone drill in his hand to complete these eight drilling and punctures, it would take at least fifteen minutes.

The next puncture injection of anhydrous ethanol was also completed within ten seconds with extremely high efficiency.

In less than a minute, the relevant data came out.

Yu Youlian showed the tablet screen to Yan Feifan, "Feifan, this is the actual path diagram of the eight punctures, and the actual dose of ethanol injected."

The computer screen shows the puncture action captured by a high-speed camera, and then the three-dimensional puncture dynamic path perspective view simulated by computer analysis.

Yan Feifan could clearly see the exact location of the puncture needle reaching the tumor and the amount of ethanol injected.

Yan Feifan has studied the tumor data of this patient in advance, and there are naturally puncture paths and ethanol doses analyzed and calculated in his mind.

He compared it...

"The eight-time puncture path and ethanol dose, with my calculation value, the maximum error is controlled within 16%..."

After pausing for a moment, Yan Feifan said with some dissatisfaction: "But the minimum error is more than ten percent."

"Your error control is quite even."

This made Yu Youlian feel relieved and said happily: "Freefan, what we are pursuing is to meet your minimum requirements first."

"As for the answer that is as close as possible to your standard, it can only be done step by step."

After a pause, she asked again: "The final effect of this puncture injection?"

Yan Feifan took the sentence and said, "I will take the lead in the surgery and check the effect."

He turned his head and happened to meet Yu Youbin's gaze, saying, "Let's start..."

At 10 or 20 minutes, Yan Feifan was taken over by the operating room, and Yu Youbin's surgical team...

Nearly two o'clock in the afternoon, Feng Jian hurried to the floor where the sterile ward of Xiaohonglou was located and saw a funny scene.

A bunch of bald heads!

In addition to Lulu's parents, brother and Yue Tingchao, four bald heads, Yu Beihua and Pan Jichuan also became bald heads.

"Are you guys?"

Yu Beihua touched his head, smiled embarrassedly, and said, "Lulu is addicted to playing bald games."

"We have to test her memory ability, and we have to bet to play bald games. If we lose, we have to shave our hair."

He pointed to his head and said, "There is twenty decimal places after Pi, and she remembers it within ten numbers."

"I'll lose!"

Yu Beihua pointed to Pan Jichuan again, "The pi is a random hundred digits, and it is also ten numbers, and she remembers it."

Feng Jian asked in surprise: "So amazing?"

Pan Jichuan nodded and said, "I am willing to accept the loss, so my hair has also been shaved."

Feng Jian said oh and asked, "Doctor Yu, Dr. Pan, did you call me here because?"

Pan Jichuan smiled and said, "We are preparing to test Lulu's pi random 500 digits. We need to find a doctor with hair, otherwise she will not cooperate."

"This little girl has learned bad things and is still enjoying it!"

"I'm not a doctor!" Feng Jian reminded!

Yu Beihua chuckled and said, "When you wear a white coat inside and a sterile suit outside, you are a doctor in Lulu's eyes."

Feng Jian covered his head and said, "Can't you think of other ways?"

"My head is not good, and it's ugly to shaved."

Lulu’s father came over and said with a smile: “This little girl Lulu has a little stubborn temper and is holding her breath, complaining that we lie to her for surgery and want to see us make a fool of ourselves.”

"She just decided to make a bet to shaved her head."

"Don't worry, if she really wins again, I will provide a quality wig."

Pan Jichuan said, "Feng Jian, don't blame me, it's time for you to devote yourself to medicine."

"Besides, you may not lose if you have a bet. Five hundred figures are a huge challenge, and it is probably the teacher who can remember it at a glance."

Under semi-force, Feng Jian reluctantly put on a white coat, sterile suit, and walked into the ward where Lulu was in a tablet.

Yu Beihua, Pan Jichuan, Yue Tingchao, and several of Lulu's families gathered in front of the large window in front of the ward and watched Feng Jian negotiate with Lulu on the bed.

"Can you still win this time?"

Pan Jichuan touched his chin and said, "I don't think the challenge will be much more important than the 500th digits."

"I bet that Lulu can win."

"One hundred yuan?"

"good!"

The result of the bet by several people was that Lulu's father and mother, as well as Pan Jichuan, believed that Lulu could win.

Yu Beihua, Yue Tingchao and Zuo Zhipeng believe that memory improvement is limiting, and Lulu will lose this time.

Pan Jichuan saw Feng Jian and Lulu in the ward start to hook their little fingers with each other, and suddenly said, "If the teacher shaves his head, will he be more stylish?"

Yu Beihua thought for a while and shook his head, "Teachers can't shave their heads. A famous doctor of a generation must always worry about their image."

He touched his head and said, "Pan Jichuan, don't think about the teacher, it's impossible to succeed."

"Think about how to fool Zhu Jian, Li Tianlin and the others into baldness, that's the truth."

Pan Jichuan said with great emphasis: "Share blessings and hardships. We become bald people, and they must be the same."

These words made Lulu's family, who heard the ears, smiled and laughed.

This is such a group of interesting doctors.

At the same time, they are full of confidence in Lulu's future.
Chapter completed!
