"I'll change the utensils for her later. The open ones will be replaced with narrow ones." Ling Ran unexpectedly didn't curse. Although Ling Ran rarely cursed in the operating room, in everyone's stereotype, the chief surgeon would curse.

of.

The circulating nurse humbly agreed, and the surgeon was replaced by another young surgeon. The nurse might start a fight at this time. When it comes to scolding in the operating room, the only thing the young doctor can defeat is the patient under general anesthesia.

Fortunately, it was Ling Ran's order, so the traveling nurse didn't think much about it, but her eyes towards Yu Yuan were not so friendly.

Yu Yuan apologized again in fear, looking a little depressed.

She originally hoped that she would have a good start when she joined the new group.

However, nothing seems to have changed much.

She couldn't even cover up the first few days.

Ling Ran's expression didn't change much, and he continued to let Yu Yuan pull the hook. After a while, he said again: "Yu Yuan, change your gloves."

"Huh? Change gloves?" Yu Yuan, who was feeling sorry for herself, was a little confused.

"Your gloves are stained with blood." Ma Yanlin explained kindly.

Yu Yuan turned her hands over and finally found a few blood spots on the joints on the back of her hands, which made her even more embarrassed.

The details of microsurgery are very demanding, and blood-free gloves and instruments are a basic requirement, because blood easily adheres to sutures.

However, Yu Yuan couldn't remember when she came into contact with blood. Thinking about it, she couldn't help but feel extremely nervous.

She hurriedly left the surgical area, took off her gloves, and with the help of the circulating nurse, put on new ones and came back. Her whole body was withered.

"Yu Yuan, you want a Debeck tooth." Ling Ran's order came immediately.

"Oh...Okay, um, give me the Deback teeth." Yu Yuan's words were unclear in her panic, as if she was an intern.

The circulating nurse had already held the Deback tooth in her hand, and when Yu Yuan said it, she immediately patted it heavily into her hand.

The "Debeck teeth", also known as "non-damaging tweezers", fell cold, but Yu Yuan calmed down a little.

In her mind, she could instantly recall the past and present life of Debeck teeth, and most importantly, its purpose: Debeck teeth are specially made forceps for holding blood vessels, and labial teeth are specially made concave and convex teeth, which are round and smooth.

Small enough to ensure that when blood vessels and other fragile tissues are clamped, they will suffer little crushing damage.

There is no doubt that Ling Ran asked Yu Yuan to pick up the Deback tooth so that she could clamp the blood vessel.

Yu Yuan couldn't help but take a breath, feeling nervous again.

"Do you know how to use Deback teeth?" Ling Ran asked Yu Yuan as if asking an intern.

And this is exactly what Yu Yuan needs most.

In order to write a thesis, she had basically no clinical contact during her graduate school years. She came to Yunhua Hospital with the horror of a paper in the first area, and there were no clinicians to give her step-by-step teaching.

Of course, Yu Yuan never worried about theoretical knowledge. She thought about it in her mind for a while and then said: "It is never allowed to use tweezers to clamp the intima of blood vessels. The adventitia is only clamped when necessary, and the movements must be precise.

light……"

"Well, the Deback teeth you have now were selected after many surgeries. The pressure will not be too great. You don't need to apply force or worry about them loosening." Ling Ran was still doing his own thing.

He explained to Yu Yuan.

His perfect replantation of severed fingers also included guidance for his assistants.

Surgery is never a one-person affair. The larger the operation, the more doctors need to cooperate. Therefore, if you want to strive for perfection, you must have the ability to coordinate and manage.

As far as Ling Ran's personality is concerned, coordination and management are not what he is good at.

If you switch to other professions such as engineers or product managers, most people like Ling Ran will be exhausted.

However, as the chief surgeon in the operating room, issuing orders with a confident attitude is a coordination and management method that meets the expectations of the surgeon.

Ling Ran neither discussed Yu Yuan's hand disability nor criticized or suggested her surgical techniques. He just treated her like an intern, explaining step by step.

After all, Yu Yuan has some foundation. After a little familiarity, she has reached Ling Ran's standard of being a second assistant on the operating table. Usually, it can be achieved by one person. With special attention and special instructions, even a disabled person can do it.

achieved.

Ling Ran sutured one blood vessel extremely quickly, and then sutured the next one.

Yu Yuan grabbed the tweezers and followed along.

When doing the first vein, Yu Yuan's movements were still a bit unfamiliar. Gradually, after doing several veins, her unfamiliarity gradually disappeared.

"Shower." Ling Ran ordered again.

Yu Yuan confidently picked up the narrow-mouth bottle.

Wow...

Water splashed again.

Ling Ran said without even frowning: "Next, we will perform perineurial anastomosis."

Yu Yuan breathed a sigh of relief and felt excited again.

Ling Ran's pace was too fast.

A few seconds later, Yu Yuan stared fiercely and asked: "Why is it the perineurium, not the epineurium?"

"My perineurium is better." Ling Ran said matter-of-factly.

"But the perineurium is much more difficult and takes a lot of time..." Yu Yuan's voice became softer and softer because Ling Ran clearly seemed to be doing it faster and faster.

At this time, there is nothing to do without the second assistant.

Yu Yuan threw away the forceps in her hand and asked the nurse to put on microscope glasses, trying hard to adapt to the surgical field of view under the lens.

I saw Ling Ran using microscopic instruments to lightly separate the epineurium at the stump of the ulnar nerve. After normal nerve growth appeared, he then circularly removed 5 mm of the epineurium at the stump, and then began to distinguish the nerve bundles.

.

When Yu Yuan saw this, her eyes widened.

A nerve can be seen as a bunch of nerve bundles, just like a rope twisted by many threads.

It is obviously not an easy task to distinguish the different functions of different silk threads.

However, Yu Yuan did not see the slightest difficulty on Ling Ran's face.

In fact, Ling Ran connected the perineurium one by one, as if there were words written on it.

Yu Yuan couldn't help but said: "The anatomical structures of nerves all look similar, how do you tell them apart?"

Ling Ran said without thinking: "Anatomy experience."

"This...how much anatomy experience is required."

Ling Ran did not answer Yu Yuan.

With the experience of 3,000 dissections, Ling Ran was able to perform hand surgery with ease.

Everyone's hands are slightly different, but if you want to grow a pair of hands that are different from 3,000 random people, the probability is extremely low, not to mention that there are various theoretical articles.

Yu Yuan was stunned, and murmured to herself: "Generally speaking, perineurial anastomosis is more effective than epineurial anastomosis, but it also takes more time. Usually, there is no need to re-open the broken finger."

Implanted... However, it is easy to choose the wrong perineurium for perineurial anastomosis. If you choose the wrong perineurium, it is better to use epineurial anastomosis. Furthermore, suturing the perineurium is more troublesome and takes more time.

It takes a long time, at least half an hour longer than the pericardial anastomosis. For replantation of severed fingers, spending so much time on pericardial anastomosis is not cost-effective..."

The nurses, anesthesiologists and Ma Yanlin in the operating room all looked at Yu Yuan strangely.

Yu Yuan shook her head vigorously: "Powerd has published an article about the therapeutic effects of epineurial anastomosis and perineurial anastomosis. Although the comparison result is that the nerve conduction velocity of perineurial anastomosis is higher, The amplitude of compound muscle action potential was significantly higher than that of the epicardial group, and the excellent and good rate was also high, but its comparison object was the ulnar nerve."

Yu Yuan paused for a moment and murmured to herself again: "The ulnar nerve is easier to sew than the nerve at the severed finger. It takes less time and is less difficult. In the same time, it is impossible to suture the severed finger. of nerves, so we cannot simply think that perineurial anastomosis is better..."

"Well, I've sewed it up." Ling Ran took his eyes away from the microscope and took off his gloves.

Yu Yuan, who was a little excited when she was talking, was stunned again.

Before she could ask, Ling Ran grabbed her neck and said, "Is it okay for Xiao Ma to do the remaining sutures?"

"It's okay, you can rest." Ma Yanlin was a little excited. After staying up for such a long time, even though he scratched his skin, he was still very happy.

Ling Ran took off his surgical clothes, threw them into the cylinder, stepped open the operating room and left.

Now he takes a nap every time he performs an operation, and no one thinks there is anything wrong.

Ma Yanlin waited for the door of the operating room to close again, then looked Yu Yuan up and down, and said, "I didn't expect that she looks like an honest person on the outside, but she flatters her so hard."

Yu Yuan was still in extreme shock. When she heard Ma Yanlin's words, she had almost no reaction and asked, "What do you mean?"

"You know that Dr. Ling is most famous for his excellent hand anatomy and perineurium suturing, so you deliberately said it's difficult. It's okay." Ma Yanlin said and laughed out loud. .

Only then did Yu Yuan realize that he was teasing her, she couldn't help but lowered her head and said, "I didn't know that I would be assigned to Dr. Ling before."

"I'll get familiar with it gradually from now on." Ma Yanlin slowly sewed the skin and said: "Dr. Ling doesn't like to talk when he does surgery, and his pace is more tense. It's easier than following other doctors. There's only one problem... …”

Yu Yuan naturally asked: "What's the problem?"

"Dr. Ling has been performing surgeries."

"Have you been...performing surgeries?" Yu Yuan thought of her scumbag surgical skills, and suddenly felt deeply uncomfortable. Suddenly, she recalled several direct orders from Ling Ran. Under Ling Ran's command, she actually performed well. played some roles...

After standing blankly in the operating room for a few seconds, Yu Yuan's round face and round eyes once again burned with a burning desire for knowledge and a strong desire for surgery...
