This was indeed Fang Nixin's politeness, but Lu Cheng became more polite to Fang Nixin after Fang Nixin revealed her identity.

As for the few stitches yesterday, I asked Lu Cheng to do it himself. Lu Cheng was confident that he could do it. However, Fang Nixin was only the surgeon at that time and Lu Cheng did not dare to act rashly without Lu Cheng's authorization.

An operation can only have one chief surgeon and many assistants. There can never be two chief surgeons. Even if there are two surgeries, they are the chief surgeons of separate teams and will not affect each other.

Because everyone’s thinking and views on disease are always different.

Fang Nixin thought for a moment, then stood up and said: "Cao Xiaohe, Lu Cheng, you come with me."

"Where are you going? Senior Sister Fang?" Cao Xiaohe asked in confusion before hearing that Fang Nixin was leaving before even reacting to Lu Cheng's words.

"We are going to a secret base where I have permission to enter for training. There is a simple arthroscope that can simulate and practice the operation of the arthroscope." Fang Nixin walked to the door and pushed it open.

"Wait for me to change clothes, and we'll take a taxi there right away."

…

Half an hour later, Fang Nixin took Lu Cheng and Cao Xiaohe to a yard near Liuyang River. The yard was full of lush trees and had several six-story buildings.

There are signs hanging on the door numbers, but because they are a little far apart, I can't see the specific situation clearly.

But where Fang Nixin led Lu Cheng and several others, the sign hanging was "Functional Science Laboratory".

There were some people coming and going in the yard, passing by in a hurry. After seeing Lu Cheng and the others, they just glanced at them and thought they were strangers, so they went about their own business.

Cao Xiaohe looked at this scene, opened his mouth a little, and asked: "Senior Sister Fang, where did you find this kind of experimental base?"

This kind of base, when Cao Xiaohe was interning in Kyoto, he was lucky enough to go to the experimental base where his third grandfather relied. It was not much different from this one. This is a place where real research is done. Ordinary people have no chance to come into contact with this kind of thing.

of.

Fang Nixin said: "This is the experiment my teacher recommended me to do here when I was studying for a Ph.D. There is also a functional science laboratory here. This is where I practiced my basic skills."

"The person in charge of the laboratory here is very familiar with me, and later he purchased a sports medicine simulation machine, which I also operate on most of the time."

As Fang Nixin spoke, she used a round blue card to unlock the door. The guard who was guarding pushed down his newspaper-reading glasses and took a few glances before putting them back on.

"It's Xiao Fang, but I haven't been here for a long time. They should be working now, right?" he asked slowly, with a smile on his face.

"Teacher Qu, I'm at work now, so I don't have much time to come here. I came here last month, have you forgotten?" Fang Nixin replied with a smile.

"It's only been a month? I'm old and my memory is bad." The man named Teacher Qu looked at Lu Cheng and Cao Xiaohe, as if he wanted to find the faces of these two young people in his memory.

"These two are my junior brothers. I will bring them here to do a small experiment for two hours. Teacher Qu, could you please be accommodating?" Fang Nixin stepped forward and said sweetly.

Teacher Qu pushed a registration book forward and said: "Register, just don't damage the equipment."

"Don't worry, Teacher Qu, I have never broken any equipment in all these years."

…

When Lu Cheng and others came to the operating table, Cao Xiaohe asked: "Senior Sister Fang, who is that Teacher Qu down there?"

"An old professor, the director of this laboratory, had nothing to do after he retired, and is now working part-time as a concierge. Eighty percent of the professors in the Department of Respiratory Medicine at the Second Affiliated Hospital are his students." Fang Nixin waved.

He replied without surprise.

Cao Xiaohe immediately opened his mouth, thinking that this man was really awesome.

Fang Nixin then turned on a switch that closed the box.

Suddenly, a screen about the size of an old-fashioned TV appeared in front of the transparent box, which was exactly what was inside the box.

Under the box are placed pieces of small stones, some large and some small. The small stones are divided into several piles. Behind the small stones are two empty boxes.

There is blank paper behind the empty box, but I don’t know what it is for.

On the top of the closed box, there are three rockers that are roughly held in one hand, and the two flush rockers below are similar to the handles of vascular forceps.

The innermost rocker is spherical, similar to the shape of an old game console.

Fang Nixin introduced: "There are three rockers here. The first two correspond to the two tweezers below. What you have to do is to use the left and right tweezers alternately to pick up the stones and put them into the box."

"Its operating mode is that of an arthroscope, and the trajectory and range of movement are similar. You need to control all 360 degrees by yourself."

"The innermost rocker is a rocker pen. If you can use it to write on a blank paper, you are almost done with it."

"Let me show you how."

After saying that, Fang Nixin immediately shook the tweezers on the left with her left hand, and slowly moved the tweezers until she was about to reach the top of the small stone. She opened the tweezers manually, then clamped a small stone, and moved it to the empty box again.

Release from above.

The movement direction of the picture is exactly opposite to the direction of her operation. The operation in the picture is actually not difficult, just move the stone.

After reading it, Cao Xiaohe was a little eager to try it, and felt that it was not that difficult.

He rubbed his hands and looked at Fang Nixin with eager eyes.

"Lu Cheng, come and try it. Xiao Cao, wait until Lu Cheng has tried it before you try again, so that you know what your current level is like." Fang Nixin did not give Cao Xiaohe a chance;

Pour a basin of cold water.

Cao Xiaohe looked like a beeping dog at that time.

Lu Cheng did not delay. He moved the tweezers twice with both hands at the same time. After comparing the operation of his hands with the movement trajectory of the tweezers in the mirror, he started the operation.

Like Fang Nixin, he placed the tweezers on top of the small stone, opened the tweezers, clamped them, raised them, moved them to the top of the box, and released them.

Then with the right hand, the same operation is repeated.

The movements are not slow either!

Fang Nixin looked a little dumbfounded. This achievement was indeed not simple. This was definitely not the first time this was done.

Cao Xiaohe looked disdainful.

That's it?

That's it?

Lu Cheng's movements obviously sped up a lot the second time.

Pebbles are irregular, so it is not easy to use tweezers to hold them. Even for ordinary people, it is a bit difficult to hold them directly with tweezers.

Operating through a blind box naturally increases the difficulty.

This requires clamping the force point accurately and preventing the stone from popping out, and the force should not be too great. It is good to do this kind of operation slowly for the first time.

Next, Lu Cheng seemed to be used to it. He operated left and right sequentially and simultaneously with his left and right hands. It was amazing to play.

Fang Nixin was stunned. The scene when she practiced for the first time was simply too horrible to watch.

It's no joke that Lu Cheng's current strength is stronger than hers.

When Fang Nixin saw this, she sighed slightly and interrupted Lu Cheng: "Okay, stop playing."

"Try this joystick again and write a word with the joystick. As long as you can write a word, you are basically successful."

Fang Nixin did not demonstrate this time because she could not write a complete character herself. Of course, simple characters like one and two were not counted.

"These two buttons, the red button is for dispensing ink, and the black button is for stopping ink dispensing."

"Okay. I understand. Thank you, Senior Sister Fang." Lu Cheng found it novel. This way of practicing mirror operation is really new.

Lu Chengcheng tried the joystick first.

Sure enough, I found it more difficult to control, and I also had to write. Writing is much more difficult than simply holding a stone and moving it. Each stroke is the opposite. I have to design it in advance in my mind and operate it.

Lu Cheng did not draw the ink first, but felt it in the air for a while.

When it felt almost the same, Lu Chengcai finally put the 'pen' inside on the paper.

After reading it, Fang Nixin reminded: "Lu Cheng, you have to pay attention. The reason why this machine controls the ink discharge and ink stop functions, instead of using the uniform ink discharge function of a signature pen, is to train your

The ability to control.”

"It is similar to writing with a brush. You have to learn to control the ink and the speed when writing. When you write for the first time, as long as you can write the handwriting well, there is no need to pay attention to the aesthetics."

You need to control the inking and stopping of ink yourself. That is to say, if you stay in one place for a long time, the ink will be darker. If you move faster, the ink may be much lighter. This is the control of force, and it is also the control of ink.

Control of timing.

When Fang Nixin reminded her, Lu Cheng immediately lifted the pen up again, and then released his hand that was about to press out the ink for a while.

Then do the operation again, which is the real reverse operation.

The first pen I wrote was a dot.

Stop inking.

Then write the second stroke, another dot.

Stop inking.

The third point is definitely a point, but this last point requires a lot of operations. This is the radical of the three points of water.

Ink comes out, ink stops.

The third point is completed.

Although one is not very pretty, the font is clearly out and can still be read.

Fang Nixin suddenly opened her mouth, muttering to herself, is surgery really meant for boys? Are girls really only suitable for internal medicine?
