The three words "major surgery" made Yan Feifan and Yu Suye excited, and also knew that the rest tonight was going to be ruined again.

Yan Feifan quickly ate the chocolate handed over by Yu Suye and the snacks, while walking back quickly.

What surprised Yan Feifan was that Yu Suye was like a Doraemon possessed. Every pocket on her body and the bag she carried with her, she could always trick her to take out one or two packs of delicious snacks, endlessly...

The two returned to the trauma surgery department and found that Dr. Chen Yu did not fool them, and it was a major operation.

This is a rare type of surgery.

Total hand bone replacement surgery.

The injured person is a thirty-one-year-old man.

He rode an electric motorcycle and rushed to a friend's party at night and accidentally fell on the road.

A cement tanker could not dodge and ran over his left hand.

After CT examination, it was found that the man's left hand bones were all comminuted fractures and there was no possibility of healing.

Dr. Chen Yu decided to perform a complete hand bone replacement surgery on this person.

The so-called complete hand bone replacement is to use a 3D printer to print out a pair of artificial hand bones with biological materials to replace the broken bones of this person...

Dr. Chen Yu said that she has mobilized the entire hospital.

The entire hospital has a total of seven 3D special medical printers, all of which are activated to urgently print the injured hand bones.

It is expected that in four to five hours, the surgical team will get a complete left-hand bone.

Because Yan Feifan's anatomy techniques were extremely exquisite, Dr. Chen Yu gave him the debridement and bone removal work before hand bone replacement.

Yan Feifan and Yu Suye, who were re-purposing their surgical gowns, walked into the operating room and saw the injured person's left hand.

Not to mention the flesh and blood, the flat ones are really like the noodles described in literature, soft and without any hardness.

Yan Feifan followed the muscle texture and used a scalpel to cut the skin and muscles on the back of the injured person's left thumb to the phalanx.

He found that the finger bones were really broken, and the large pieces were just the size of beans.

Yan Feifan needs to clean up these broken bones one by one.

Anyone who leaves a little bit of bone the size of a needle nose may bring unbearable pain to the injured in the future.

This is a patient and meticulous job.

Yan Feifan, who has been in the consciousness world for countless years, lacks the most patience.

In the microsurgery field, with the assistance of Yu Suye, he removed the broken bones while repairing the damaged blood vessels, nerves, tendons, skin and muscles.

This work is tedious and boring, but Yan Feifan enjoys it.

For him, as long as he stands on the operating table and holds a scalpel, no matter what the job he is facing, it is a kind of enjoyment...

Nearly three hours later, Chen Yu, who was preparing for the operation, came to the operating room with several assistants and students.

Chen Yu walked to the operating table, but his eyes were involuntarily attracted by a stainless steel tray beside Yan Feifan.

In the tray is a pair of hand bone skeletons composed of tiny pieces of broken bones.

At present, there is still a shortage of finger bones for small fingers.

Chen Yu noticed that the broken bones that Yan Feifan took out with tweezers seemed to have just been placed in the tray casually, without delaying a second.

But as soon as you put it casually, the small piece of bone was placed in the most correct position.

Order, precision and perfection seem to have become the pursuit of Yan Feifan from the bone marrow, and also the standards of doing things.

Chen Yu took two steps back and waved again. Several assistants and students standing in the observation area approached her.

She pointed to the tray that contained broken hand bones and whispered: "I know, you have a lot of complaints about my preference for Yan Feifan during this period."

"Look at the hand bones in this tray, ask yourself, can you do this as you wish?"

"When you see the small and know it, Yan Feifan's high requirements for himself have been refined into all aspects, and habits have become natural."

Chen Yu raised his voice and said indifferently: "Don't be jealous of other people's achievements and preferential treatment, look at the gaps and reflect on the shortcomings."

"I can give you the opportunity, too."

"The question is, do you have the confidence to catch it?"

Several assistants and students dare not speak out, but there were also one or two people with dissatisfied expressions on their faces...

Chen Yu waited for more than ten minutes before Yan Feifan completed all the debridement and bone removal work.

Yan Feifan gave up the position of the main sword to Chen Yu.

His next job was to further polish the eleven printouts of finger bones.

Although the machine accuracy is already very high, due to errors in measurement, modeling and other data, the printed phalanx still needs to be polished and corrected.

Yan Feifan, who has a close understanding of the structure of the human body, is undoubtedly the best candidate for this job.

Chen Yu did the job, with the help of Yu Suye, implanted the polished finger bones of Yan Feifan into the corresponding position in the left hand of the injured person.

There are two most difficult parts of this job.

First, fix the tendon that controls flexion and extension on the artificial phalanx.

The second refers to the suture treatment of bone and joint connective tissue.

At 2:30 in the morning, the last printed phalanx was sent to the operating room.

At 4:40 in the morning, Yan Feifan, who had a short rest, replaced Yu Suye and served as Dr. Chen Yu's assistant.

At 7:00 in the morning, the total hand bone replacement surgery was successfully completed...

After washing, Yan Feifan and Yu Suye dragged their tired bodies to the staff cafeteria and ordered a sumptuous breakfast.

Although he was so hungry that he was rumbling, Yan Feifan didn't have much appetite. He knew that this was because of his physical and mental exhaustion.

Yan Feifan could only force himself to eat this meal that was usually very attractive but now it tastes like chewing wax.

Halfway through the meal, he received a call from Director Lu.

"Director Chen called me just now and said you had been busy all night with her for surgery."

"Xiaoyan, I don't have to come here today. Go home and have a good rest."

Yan Feifan felt relieved and said with peace of mind: "Thank you for your understanding."

To be honest, he felt that his body could not hold on anymore, so he planned to ask Director Lu for leave.

It is naturally easier to obtain approval and understanding if Director Chen asks for leave on his own than to ask for leave on his own.

"Xiaoyan, let me tell you another good news."

On the phone, Lu Jun's voice became vivid.

"I have received a precise notice that the research topics on nerve internal nourishment we have applied for has received special support from the National Health Commission."

"The first phase of the approved research fund is 8 million."

"When the approval is officially released, we can recruit volunteers and conduct clinical surgical trials."

"This Thursday, we sit down and discuss it..."

After the call with Director Lu, Yan Feifan was in a good mood and felt that his appetite had improved a lot...

After breakfast, Yan Feifan and Yu Suye looked at each other and found that they were so tired that they couldn't even open their eyelids.

They gave up the idea of ​​returning to Zuimo Huating Community. If they ride a bike back in this state, something might happen halfway.

The two arrived at the Qin Ying Medical Teaching and Research Department on the second floor of the emergency department.

Today is Tuesday, Teacher Qin Ying’s outpatient date.

The teaching and research room is empty.

There are sofas for people to rest here, blankets, pillows and other items prepared by Yan Feifan and Yu Suye.

It was prepared for the situation like today.

Yan Feifan and Yu Suye cleaned up the sofa simply, but there was no difference between men and women. They lay on the sofa and fell asleep together...
Chapter completed!
