Zhang Yan's look at this made Li Dazhuang feel a little scared, as if when he first started practicing medicine, his superior doctor would look at him like this when he made mistakes.

There was no reprimand, just a pair of sharp and serious eyes.

It makes people shudder.

"This is Dr. Zhang's unique skill. He sets the bone through the stubble of the bone without internal fixation. This is conducive to the growth of the bone, and the patient does not need to suffer twice and remove the fixed bracket." Chu Yunlong explained in a low voice.

"Isn't this easy to cause problems? If the patient accidentally touches his finger, the operation may fail." Li Dazhuang questioned in a low voice.

"External fixation can be performed!" Chu Yunlong glanced at Li Dazhuang as if he were a fool.

You, the director of general foreign affairs at the Union Medical College, are fake, right?

Don’t you know such a simple question?

Li Dazhuang was once again insulted by Chu Yunlong's eyes, and was secretly annoyed.

I am the director of general surgery, not the director of orthopedic surgery.

Don’t you know how busy general surgery is?

I am so busy every day that I have no time to study internal and external bone fixation.

Zhang Yan didn't hear the conversation between Chu Yunlong and Li Dazhuang at all. At this time, all his attention was on the needle and thread in his hand. How thick can the artery in his finger be?

The diameter of finger arteries is 0.5 to 0.7mm, and the diameter of veins is 0.3 to 0.5mm.

Under the current situation where the magnification of the microscope was not enough, Zhang Yan could only use all his concentration and did not dare to be distracted in the slightest while suturing.

The ideal state for replanting a severed finger is to suture six blood vessels, two arterial blood vessels, and four venous blood vessels.

This is completely a race against time.

Zhang Yan's concentration was so infected that Chu Yunlong and Li Dazhuang stopped talking and quietly watched Zhang Yan's needle flying.

After suturing the blood vessels, check the blood supply and find that the blood supply is normal.

In fact, there are many blood vessels on the fingers. Those blood vessels are too small and are capillaries. Under the current technical conditions, they cannot be sutured at all.

We can only wait for the human body to correct its deviation and activate its compensatory function to replace the function of this part of the capillaries.

The human body is very miraculous, and its own error correction and compensatory capabilities are very powerful.

Many surgeries cannot repair and achieve unachievable results, so we rely on the body's own correction and compensatory capabilities to repair organ damage.

A typical example is a patient with cerebral infarction. Even in later generations, doctors do not have much control over the brain.

For many patients with cerebral infarction, doctors can only remove part of the accumulated blood and hope that the body's correction and compensatory functions will work.

After Zhang Yan checked the blood supply, he then sutured the nerve bundles, which were a little thicker than the blood vessels.

But the requirements are still higher, the finger function is restored, and the anastomosis of the nerve bundles accounts for more than half.

Vascular anastomosis involves whether the finger can survive.

The recovery of finger function depends on the anastomosis of nerve bundles and the suturing of tendons.

These two points are the key to functional recovery after surgery.

After quickly suturing the nerve bundles, Zhang Yan began to suture the tendons.

"What kind of suturing technique is this?" Li Dazhuang couldn't hold back and shouted again.

Zhang Yan used a suturing technique that he had never seen before.

If you look closely, this technique has the shadow of many suturing techniques used today. If you look more closely, you have no idea what technique Zhang Yan used.

"Quiet!" Zhang Yan looked up at Li Dazhuang and said two words.

Then lower your head and continue suturing the tendon.

Just two words made Li Dazhuang blush.

What happened to you today?

How could you be so out of sorts?

Just two words made Li Dazhuang doubt his life.

Li Dazhuang was full of self-blame, but he did not take Zhang Yan's scolding seriously. If he was the surgeon and someone dared to interrupt and disturb the operation, he would definitely kick that person out.

If it's serious, I won't even think about showing up in my own operating room in the future.

Zhang Yan didn't say anything else. After scolding him, he continued to concentrate on suturing the tendons.

Nearly an hour has passed by this time.

Excluding the time it takes for the patient to go to the Union Medical College Hospital and then transfer from the Union Medical College Hospital, the patient only has more than three hours of optimal surgery time.

There are still more than two hours left.

Still very urgent.

After suturing the tendon, the next step is to suture the subcutaneous tissue and skin.

Zhang Yan raised his head and glanced at the people in the operating room. He wanted to find someone to suture his skin.

However, I looked around and couldn't find the right person.

The perfect tool man Peng Dahai is not here, and neither is Zhao Pengcheng.

My four apprentices are not good enough yet. I don’t feel comfortable leaving the skin suturing work to them.

Not for anything else, they were afraid that Zhao Shengli and Qian Hongying would touch their fingers carelessly and deform the newly connected phalanges, which would lead to the failure of the operation.

After looking around and seeing no one helping him, Zhang Yan sighed secretly.

immerse yourself in sewing.

Zhang Yan couldn't help but speed up the process of suturing the skin. Small things like suturing the skin shouldn't take up his time.

We must train several tool people as soon as possible.

Zhang Yan pondered secretly.

After suturing the skin, Zhang Yan performed a nerve reflex test to check the anastomosis of the nerve bundles.

Nerve reflexes are good.

Zhang Yan continued with the next finger.

While Zhang Yan was undergoing intense surgery, the two brothers Zhang Ping and Zhang An began another miserable day.

Last night, the two of them took some hot water, wiped their bodies clean, and applied the ointment given by Zhang Yan.

These two brothers will not save Zhang Yan money.

Anyway, after working for a day, my whole body hurts everywhere.

The two of them simply wiped it all over their bodies, not even leaving that spot alone.

Needless to say, the ointment is very effective. After applying it, it feels refreshing and cool at first, which is very comfortable.

However, within two minutes of feeling comfortable, the coolness turned into hotness.

The feeling of being in a raging fire, with a ball of fire burning on the body, made Zhang Ping and Zhang An miserable.

In particular, the two unlucky children also applied ointment on that area, thus doubling the pain.

The two of them were rolling on the bed in pain.

The painful wailing sound startled the people in the dormitory.

A few people who were practicing their skills were so frightened that they almost withered.

Fortunately, the pain did not last too long. After the initial intense pain, Zhang Ping and Zhang An calmed down.

The effect of the medicine is continuous, but it will be quite violent in the first minute or two. After that, although the high temperature continues to penetrate from the body surface to the muscles and bones, it is still very painful, but the pain is already bearable.

The pain lasted for nearly an hour before disappearing.

The two people, exhausted from the torture, had no time to clean up and just pulled the quilt over and fell asleep.

The next day, the ointment took effect. When they woke up, they felt full of energy and endless energy.

The two of them were even more grateful to Zhang Yan.

After breakfast, we came to the loading and unloading team with great energy.

When we arrived at the loading and unloading team, other temporary workers had already arrived and were cleaning the office. Someone went to the boiler room to get hot water.

These two brothers are the masters of the house, with hands outstretched for food and mouths open. How could they ever do this?

Stick it like a stick and watch others work.

Not only that, when someone else brought hot water, the two of them were not polite and poured themselves a full jar of water.

Because the two of them had just arrived, others couldn't figure out their backgrounds, and no one said anything.

However, all this was seen by Zhao Changsheng.

My heart said: OK! Boy, I was as tired as a dead dog yesterday, but today I feel relieved again.

Thinking of Zhang Yan's explanation, Zhao Changsheng turned around, called Wang Yuantang to his side, and whispered a few words.
