Great Doctor Ling Ran

Chapter 4: End-to-end continuation

In the big room, Lei Beisha practiced the concept of playing eight sticks and giving a sweet date, and comforted: "In the beginning of the internship, everyone mainly focuses on observation, pays attention to the learning of methods, studies hard, and works hard. Combination of Yi and Yi. Today, the main purpose is to give a demonstration to everyone. In the future, you will have plenty of time to spend in the practice room. When the time comes, you won’t be able to come if you don’t want to.”

Seeing that Lei Beisha's attitude had improved, Wang Zhuangyong quickly raised his white-gloved hand and asked, "Director Lei, how difficult is the docking of the white mouse, and where is the difficulty?"

"How difficult is it? How do you put it?" Lei Beisha thought for a moment and said, "Let me describe it. The hand surgery department of our Yunhua Hospital not only has students from your medical school come for internships, but also accepts nearly a hundred doctors from the province every year. Doctors from other hospitals in the country come to practice and learn, and when these doctors leave, they can complete the docking, and the blood flow pass rate of 95% is only in the single digits."

The students all gasped in amazement.

Doctors who can come to Yunhua to return to the furnace, no matter how weak they are, are stronger than medical students who have never been on the operating table. With such a judgment, the students will be even more in awe when they watch the undocked tail of the white mouse.

A few minutes later, Kang Jiuliang and Ling Ran sat on both sides of the table. The objective lens of the double-person binocular microscope is facing the tail of the white mouse, and the two ends of the machine above each provide a pair of eyepieces for Kang Jiuliang and Ling Ran.

"When we practice normally, we cut the tail of the white mouse into 60 to 80 segments. Today's situation is special, so we cut a little less." Kang Jiuliang picked up the scalpel while turning on the microphone on the side of the table to speak.

"The white mouse is so cute, don't cut its tail." A girl hid in the crowd and shouted.

Although he guessed that she was joking, Kang Jiuliang still seriously explained: "Experimental animals are the unsung heroes of our medical school. Everyone uses experimental animals to practice in order to improve technology and better improve human well-being. And within the scope of ability, Everyone should make good use of every experimental opportunity as much as possible, and reduce the pain of experimental animals within the scope of their ability, so when doing exercises, you must be serious... this student, what are you doing?"

While Kang Jiuliang was speaking, he saw that Ling Ran had cut the anesthetized white rat's tail into dozens of pieces...

"You said cut a little less today, but I cut 42 sections, is that too little?" Ling Ran's scalpel shone with silver light.

The eyes of the students below were even brighter, including the girl who said "the white mouse is so cute" just now, and she was so excited that she wished that she was the one who used the knife just now.

"Cut it off, then you have to follow the command." Kang Jiuliang looked at the pile of broken tails, and he couldn't put them back together again.

No, they are now ready to fight together.

"Let me demonstrate first." Kang Jiuliang held the tweezers in his left hand and the needle holder in his right hand, and said, "We are using microscopic medical instruments. Many students have probably never touched them. The main feature is that they are small and compact. The thickness of the suture is only one-tenth of a human hair... this classmate, by the way, what is your name?"

"Ling Ran." Ling Ran replied.

"Don't like talking?"

"good."

"In the future, I will be talkative. When surgeons perform operations, they are always talkative." Kang Jiuliang's appearance changed obviously during the operation and before the operation.

Ling Ran let out an "oh".

Kang Jiuliang couldn't help but said, "Aren't you wondering why?"

"Because I'm bored." Ling Ran replied.

The interns laughed softly.

Kang Jiuliang was stunned for a moment, and asked, "Is the question I asked too boring?"

"It's because surgeons are so boring when they're operating."

"Indeed, the operation takes a long time, and it's really boring. When we do a hand operation, it usually lasts ten or twenty hours at a time. If you don't want to talk, the people around you also want to talk." Kang Jiuliang disagreed. Then he struggled with Ling Ran's puns, while talking and operating, as if the two were not interfering.

At least in the eyes of the interns, the rhythm in Kang Jiuliang's hands is completely different from the rhythm in his mouth.

The so-called practice makes perfect, that's about it.

Ling Ran was also familiar with the details of Kang Jiuliang's operation in his mind.

The docking of white mice is, in the final analysis, vascular anastomosis.

To suture the disconnected blood vessels, it is necessary to suture six to eight stitches on the small cross-section of the blood vessels, so as to ensure smooth blood flow without obstruction or leakage.

In the process of suturing, it is also necessary to pay attention not to produce cavities and dead spaces.

To say how skilled a surgeon is, it actually depends on these specific and subtle concerns.

For example, docking and reconnecting, hand surgeons have been trained for two or three years, and they can always be connected. However, whether it is used as usual after the operation, whether there is any dull pain or even complications, depends not only on the condition of the rat itself, but also on the condition of the rat. Surgeon's operation.

In short, it is not easy to sew, and it is even more difficult to sew well.

"Do you know the stitching method I use?" Kang Jiuliang was bored talking to himself, and asked Ling Ran directly.

"It's a simple interrupted suture." Ling Ran didn't say much.

"Are you familiar with it?" Kang Jiuliang asked, but he answered by himself: "You should be familiar with it. This is the most commonly used and simplest suture method, also called nodular suture, right? One stitch is used for one stitch." Jie, when I practiced at school, this is what I practiced most, how about you?"

"Almost." Ling Ran still answered concisely. He watched Kang Jiuliang's operation, his mind was full of information surging, and he didn't want to chat at all.

"That's fine, I'll try it for you." Kang Jiuliang suddenly became a little upset. Uncle, I'm very busy, okay, I've worked so hard to give you a demonstration, why can't I even chat with you.

Originally, he wanted to do a few more anastomoses to familiarize Ling Ran, but now that he has finished one blood vessel anastomosis, he simply let go.

Ling Ran was stunned for a moment, but without thinking too much, he said "OK" and grabbed the needle holder.

Kang Jiuliang kept his eyes on the eyepiece, but now he couldn't help but raised his head and glanced at Ling Ran.

As the saying goes, an expert will know if there is one as soon as he makes a move. For microsurgery, picking up the needle holder without shaking your hands is the basis for getting started.

In order to suture 8 needles on blood vessels with a diameter of 0.5 cm, the suture needles they used at this time were only one-fifth the thickness of a hair. When ordinary people hold the needle holder, the tip of the needle at the front will keep vibrating.

Its magnitude is so large that under the microscope, it seems to be dancing.

In fact, any doctor who has not specialized in microsurgery will feel dizzy when he picks up the needle holder used under the microscope, so he has to hold it for a long time to practice.

Some doctors have to raise their arms to swell up in order to practice acupuncture.

As for medical students…

Kang Jiuliang couldn't help asking: "You Yunhua University School of Medicine, are you still practicing microsurgery?"

"My family runs a small clinic." Ling Ran spoke nonsense, and the needle under the microscope was aimed at the thin blood vessels in the tail of the white rat.

Kang Jiuliang hurriedly focused, but saw that the blood vessels in the tail of the white mouse did not move under the microscope.

Kang Jiuliang couldn't help raising his eyebrows.

Under the microscope, the blood vessels do not vibrate at all, indicating that they are not stretched at all. This is not a basic requirement, but a very high level.

In order to practice this technique, some doctors will put the foam in a basin, and then sew and tie knots on the foam. The goal is that the foam cannot move at all.

It is also suturing a severed finger. If the suture level is done at this level, the finger's recovery ability and future function will be somewhat stronger.

In a trance, the stitching of an anastomotic point was completed.

Kang Jiuliang didn't even notice the specific time, his only judgment was that he was at least faster than himself.

Thinking of this, Kang Jiuliang hurriedly looked at the anastomosis of blood vessels under the microscope, and saw that the exposed knots were quite consistent. From the appearance alone, it was pleasing to the eye, and there was no such thing as a false knot. class of errors.

This is a textbook-style stitching and knotting of blood vessels, and there is no fault at all.

Small clinic? Kang Jiuliang raised his head and glanced at Ling Ran, thinking: How many fingers must be chopped off in your small clinic to develop such a suture level
