In the large room, Lei Beisha carried out the principle of giving a carrot and stick. He comforted them and said, "At the beginning of the internship, everyone should focus on observation. You should pay attention to the learning of methods, study hard, practice hard, and strike a balance between work and rest. Today, I will mainly give you a demonstration. In the future, you will have plenty of time to soak in the training room. By then, you will have no choice but to come. "
Seeing that Lei Beisha's attitude had changed for the better, Wang Zhuangyong quickly raised his white-gloved hand and asked, "Department Director Lei, how difficult is the tail replantation of this white rat? What is the difficulty?"
"How difficult? How should I put this?" Lei Beisha thought for a moment and said, "Let me describe it. In the Hand Surgery Department of Yun Hua Hospital, besides the medical students who come for internship, there are also nearly a hundred doctors from other hospitals in the province who come to practice and learn every year. When these doctors leave, there are only single digits who can complete the tail replantation and have a blood flow rate of 95%."
The students exclaimed in unison.
No matter how weak the doctors who could come to Yun Hua Hospital were, they were still better than the medical students who had never been on the operating table. With this judgment, the students were even more in awe when they looked at the tail replantation of the white rat.
A few minutes later, Kang Jiuliang and Ling Ran sat on both sides of the table. The objective lens of the two-person binocular microscope was aimed at the white rat's tail. The two ends of the machine above each provided a pair of eyepieces for Kang Jiuliang and Ling Ran.
"When we practice normally, we will cut the white rat's tail into 60 to 80 pieces. Today's situation is special, so we will cut less." Kang Jiuliang turned on the microphone on the side of the table and picked up a scalpel as he spoke.
"The white rat is so cute, don't cut its tail." A girl hidden in the crowd shouted.
Although he guessed that she was joking, Kang Jiuliang still explained seriously, "Experimental animals are the unsung heroes of our medical school. Everyone uses experimental animals for practice to improve their skills and improve the well-being of humans. And within the scope of your ability, everyone should also try to make the best use of every experimental opportunity and reduce the pain of the experimental animals within the scope of your ability. Therefore, you must be serious when you practice … Student, what are you doing? "
As Kang Jiuliang spoke, he saw that Ling Ran had already cut the anesthetized white rat's tail into dozens of pieces …
"You told me to cut less today, so I only cut forty-two sections. Is it too little?" Ling Ran's scalpel shone with a silver light.
The eyes of the students below the stage lit up, including the girl who said "White Mouse is so cute". She was so excited that she wished she was the one who had stabbed the mouse.
"So be it. Next, you have to listen to me." Kang Jiuliang looked at the pile of broken tails. He couldn't let him put them back together.
No, they were preparing to fight now.
"Let me demonstrate first." Kang Jiuliang held the forceps in his left hand and the needle holder in his right hand. He said, "What we're using now is called a microscopic medical instrument. Many of you probably haven't come into contact with it before. Its main characteristic is that it's small and compact. For example, the thickness of the suture thread we're using now is only one-tenth of a human hair … Student, by the way, what's your name?"
"Ling Ran," Ling Ran answered.
"You don't like talking?"
"Not bad."
"You'll be talkative in the future. Surgeons are always talkative when they perform surgery." Kang Jiuliang was obviously different during the surgery compared to before the surgery.
Ling Ran hummed in acknowledgment.
Kang Jiuliang couldn't help but ask, "Aren't you curious why?"
"Because I'm bored," Ling Ran answered.
The interns chuckled softly.
Kang Jiuliang was stunned for a moment and asked, "Is it because my question is too boring?"
"It's because surgeons are too bored when they perform surgery."
"Indeed, surgeries take a long time, and it's really boring. When we perform a hand surgery, we often perform it for ten or twenty hours. Even if you don't want to talk, the people next to you will want to talk, right? " Kang Jiuliang no longer bothered about Ling Ran's pun. As he spoke, he operated as if the two of them didn't interfere with each other.
At least in the eyes of the interns, the rhythm of Kang Jiuliang's hands and the rhythm of his mouth were completely different.
As the saying went, practice makes perfect. This was probably how it was.
Ling Ran was also familiarizing himself with the details of Kang Jiuliang's operation in his mind.
At the end of the day, the tail replantation of a white rat was a blood vessel anastomosis.
To suture the severed blood vessel, six to eight stitches were needed on the section of the small blood vessel to ensure that the blood flow was smooth, unobstructed, and without leakage.
During the process of suturing, they also had to pay attention to not creating any cavities or dead spaces.
To judge a surgeon's skills, it was actually based on these specific points of attention.
For example, a doctor from the Hand Surgery Department could always reconnect a severed tail after training for two to three years. However, whether it could be used as usual after the surgery, and whether there would be any pain or even complications depended on the condition of the white rat and the surgeon's operation.
In short, it was not easy to suture, and it was even harder to suture it well.
"Do you know the suture method I used?" Kang Jiuliang was bored of talking to himself, so he asked Ling Ran directly.
"It's a simple interrupted suture." Ling Ran did not say much.
"Are you familiar with it?" Kang Jiuliang asked, but he answered his own question, "I should be familiar with it. This is the most commonly used and simplest suture method. It's also called the nodule suture, right? When I was practicing in school, I always did this kind of thing. What about you guys? "
"Pretty much." Ling Ran's answer was still concise and comprehensive. He looked at Kang Jiuliang's operation, and his mind was full of information. He did not want to chat at all.
"Alright, I'll let you try." Kang Jiuliang suddenly felt a little unhappy. 'I'm very busy, okay? I worked so hard to give you guys a demonstration, why don't I even know how to chat?'
He originally wanted to perform a few more anastomoses to let Ling Ran familiarize himself with it. Now that he had completed a blood vessel anastomosis, he might as well let go.
Ling Ran was stunned for a moment, but he did not think much about it. He said, "Okay," and grabbed the needle holder.
Kang Jiuliang's eyes had never left the eyepiece. At this moment, he could not help but raise his head and glance at Ling Ran.
As the saying went, an expert would know whether or not he was an expert the moment he made his move. For microsurgeries, holding the needle holder without trembling was the foundation of learning how to get started.
In order to suture eight sutures on a blood vessel that was 0.5 inches in diameter, the suture needle they used was only one-fifth the thickness of a hair. When an ordinary person held the needle holder, the tip of the needle would continuously tremble.
The tremble was so great that it looked like it was dancing under the microscope.
In fact, all doctors who did not specialize in microsurgeries would feel dizzy when they held the needle holder under the microscope. They had to hold it for a long time to practice.
Some doctors' arms were swollen because they wanted to practice with needles.
As for medical students …
Kang Jiuliang could not help but ask, "Do you still practice microsurgeries in Yun Hua Medical College?"
"My family runs a small clinic." Ling Ran made up a lie, and the needle under the microscope went toward the blood vessel at the tail of the white mouse.
Kang Jiuliang quickly focused his attention, but he saw that the blood vessel at the tail of the white mouse did not move under the microscope.
Kang Jiuliang could not help but raise his eyebrows.
Under the microscope, the blood vessel did not tremble at all, which meant that it was not pulled at all. This was not a basic requirement, but a very high level of skill.
Some doctors would put foam in a basin of water to practice this skill, and then suture and tie knots on the foam. The goal was to make sure that the foam did not move at all.
It was the same as suturing a severed finger. If the suturing was done with this level of skill, the finger's recovery ability and future function would be stronger.
In a daze, the suture of the anastomosis point was completed.
Kang Jiuliang did not even notice the specific time. The only thing he could judge was that it was at least faster than him.
When he thought of this, Kang Jiuliang quickly looked at the anastomosis point of the blood vessel under the microscope. He saw that the exposed knots were quite consistent. It was pleasing to the eye just by looking at it, and there were no mistakes such as fake knots.
This was textbook suturing and tying of blood vessels. There was no mistake at all.
