Fliggy's air logistics was very fast, and in the afternoon, Chen Fan got what he wanted.

"Xiaofan, that is Johnson & Johnson's 70 cm sutures, I asked someone, novices use this two 0 sutures, the friction is relatively large, it is easy to cause traction, it is a more difficult to control model, and it is also a practice material recommended by many foreign medical schools. The only problem is that the cost is more expensive than domestic goods, and the average student can't afford to do training, of course, this is not a problem for our family, and it is not as good as the water bill. Xu Tingting introduced on the phone.

Chen Fan: "Okay, Sister Ting, I know." ”

He has always felt that the old Xu family is too wasteful, and he usually drinks more than a thousand bottles of water, and cooks too.

"Or I'm thrifty, I've always used the spring water on Changbai Mountain, and when Sister Ting comes over, I will definitely teach her how to live, it's too wasteful, and it's not good for educating the next generation." Chen Fan shook his head, for the things that will happen in the future, he naturally has to talk about it later.

"The master said that the sewing method is a powerful basic skill, and the sewing method under the microscope is the basic skill among the basic skills, so let's find the sewing method." Chen Fan plunged headlong into the sea of books brought to him by Xu Tingting.

Stitching method

It didn't take long to find it

"The basis of the sewing method is the butt seam method," the butt seam method includes the simple interrupted seam method, the simple continuous seam method, the subepidermal seam method, the press seam method, the cross seam method and the continuous seam seam method, a total of six types. ”

"Then there's varus sutures and tension sutures."

Look at the patterns in the book

Chen Fan made another difficulty, even if he knew how to sew, no one was willing to sew it for him.

That big living person is willing to make a hole for himself and sew it for someone else?

"Then the question is, how did the master practice in medical school in the first place?"

Chen Fan thought about it, and when he thought about it, he saw the bananas on the table, could it be ......

I see, no wonder the master likes bananas so much, all to practice sewing.

Alas ~ This master, don't you say it earlier if there is such a factor?

What's so shy about this? It really is.

Chen Fan subconsciously forgot about the little nurse......

Pick up the scalpel and gently slice the banana without hurting a single piece of the flesh.

As in the book, he held the tweezers in his left hand and the needle pliers in his right hand, and began to thread the needle and lead wires......

For Chen Fan, this requires feeling, there is always a time when it is perfect in the constant experiment, he just needs to remember the feeling of perfection, it is enough.

But this time, he practiced all afternoon.

I looked at the sky outside

It's already dark

No, you have to sleep, only by sleeping well can you keep that perfect long hair, otherwise you are already smart, fortunately there is no top, you really have to become stronger because of staying up late, Chen Fan can cry to death.

The next morning

After giving the master hot milk as a sign of respect

Chen Fan began to practice again

an hour

Chen Fan was lucky enough to be perfect once

How do you determine perfection? The result of his practice is the same as the three-dimensional 3D pictures in the book, which is perfect, and the big data in his mind filters out the feeling of success, and then Chen Fan remembers the feeling of perfection.

Next

Repeat perfectly

The left hand holds the tweezers, the right hand controls the needle forceps, the moment the needle falls on the skin of the banana, countless information jumps out of the mind, and there is no special consideration, the wrist is rotated, the needle is pierced, and it is extremely smooth.

Needle in, thread out, knot......

At this time, Chen Fan reached the peak of needlework

During the whole stitching process, the banana remained motionless, completely uninvolved in the needle entry and exit, and was neatly aligned from head to end.

The spacing between the two stitches is exactly equal, as if measured with a ruler, and the knotting is even more beautiful and neat like an industrial tie......

Accurate direction, precise strength, skillful judgment, just the right puncture depth and arc, uniform and stable technique...... Although it seems to be a simple needlework, the actual operation is not simple at all.

After that, it's under the microscope

Find the medical van at Renhe Hospital

Chen Fan pulled out a dusty microscope from the bottom.

Microsurgical instruments

When the actual operation is performed, the doctor looks at the lens of this microscope and then judges the operation on his hand. Let's search for books

Plug it in and connect it to the circuit.

Chen Fan cleaned up the machine

Find the perfect needle under the microscope

And then remember the perfection again

Repeat perfectly afterward!

It took another three days

After you have familiarized yourself with all the stitches in the book

And the hands do not tremble

Some doctors have to lift their arms and swell them off in order not to shake in order to practice.

But Chen Fan won't, once he gets serious, he will be precise and mechanical, like an intelligent machine.

Have you ever seen a robot hand tremble?

You may have seen it

But Chen Fan asked himself that he was much stronger than a machine

If you ask why

Chen Fan: Ji Cao, don't six, I'm hanging on the wall!

System: "Congratulations to the host, you have learned the master suture method, you are proficient in all suturing procedures, and the surgical level is equivalent to one-tenth of the completion of the study!" ”

"Reward Brain Domain Development 0.3%"

At present, Chen Fan's brain domain has developed 15.9%

All surgeries require sutures, perfect sutures, and perfect sutures can minimize the scarring of the person being operated on, which is the most common and basic medicine in surgical medicine.

"Friendly reminder, please ask the host to complete a suture surgery alone, and you can get a brain domain reward and additional rewards."

Just learned how to stitch and thought about running?

Chen Fan felt unrealistic

But when you think about it, this is a disaster area, an earthquake-stricken area, what is the most? The largest number of people need stitches.

Many people with minor injuries simply need to clean the wound, then suture it and get an anti-inflammatory injection.

So Chen Fan has a chance!

But vascular anastomosis, that is, vascular sutures, he won't!

What if you won't?

Looking for Lu Chenxi?

Forget it, the master is saving people, so there shouldn't be time to teach me.

Only the old ways can be used

Self-study!

Vascular anastomosis, again, must be mastered by surgeons.

Many times, we are injured and will injure arteries, veins, and other blood vessels that bleed profusely.

So it's not a matter of blood vessel rupture

Stitches are also required

Also under the microscope, this type of surgery is done.

Soon, Chen Fan found the introduction of vascular anastomosis.

The diameter of the blood vessels of the human finger is only 0.3 mm, while the diameter of the tail blood vessels of the white mouse is about 0.5 mm, which is about the same thickness as the middle finger blood vessels of ordinary people.

Therefore, the tail docking of white rats is a perfect practice operation.

Practice with white mice

It's something that all doctors go through

However, small blood vessel anastomosis, to put it bluntly, is a surgery that connects the broken small blood vessels in series to keep the blood flowing.

Blood is the source of life, and where blood circulates, nutrients are supplied.

Where the nutrients are supplied, the cut flesh will die, and the dying tissue will resume its work.

The human body is the most mysterious treasure, Chen Fan originally played the profession of a doctor in life, he didn't know that the future would allow him to find the real treasure of the human body.
