In the big room, Lei Beisha was implementing the concept of beating eight sticks and giving a sweet date, and comforted him: "At the beginning of the internship, everyone mainly focuses on observation, pays attention to learning methods, study hard, and combines work and rest. Today, we mainly show you a demonstration. In the future, you have time to spend in the practice room. At that time, you will not be able to come."

Seeing that Lei Beisha's attitude improved, Wang Zhuangyong quickly raised his hand wearing white gloves and asked: "Director Lei, how difficult is this white rat's disconnection and continuous connection, and what is the difficulty?"

"How difficult is it? How can I say this?" Lei Beisha thought for a while and said, "Let me describe it. In addition to the internship of your medical school students in our Yunhua Hospital, nearly 100 doctors from other hospitals in the province come to practice and study every year. When these doctors leave, they can complete the requirement of 95% of blood flow rate, only single digits."

The students all exclaimed.

The doctors who can go back and forth to Yunhua are weaker than the medical students who have never been on the operating table. With such a judgment, when they look at the broken tails of the mouse, the students will feel even more awe.

A few minutes later, Kang Jiuliang and Ling Ran sat on both sides of the table. The objective lens of the double binocular microscope faced the tail of the mouse, and at both ends of the machine above each provided a pair of eyepieces to Kang Jiuliang and Ling Ran.

"When we practice normally, we will cut the tail of the white rat into 60 to 80 segments. Our situation today is special, so cut less." Kang Jiuliang opened the microphone on the side of the table and spoke, and picked up the scalpel.

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

Although she guessed she was joking, Kang Jiuliang still explained seriously: "Experimental animals are the unsung heroes of our medical school. Everyone practices experimental animals in order to improve technology and better improve human welfare. Within the scope of ability, everyone should also make the best use of every experimental opportunity as much as possible, and within the scope of ability to reduce the pain of experimental animals. Therefore, when doing exercises, you must be serious... What are you doing, this classmate?"

As Kang Jiuliang spoke, he saw that Ling Ran had cut the anesthetized white rat tail into dozens of pieces...

"You said I cut a little less today, and I cut 42 pieces. Is it too few?" Ling Ran's scalpel flashed with silver light.

The students below even looked at each other, including the girl who said "White Rat is so cute", and she was so excited that she wanted to be the one who used the knife just now.

"Cut it and cut it. Next you have to follow the command." Kang Jiuliang looked at the pile of broken tails, and he couldn't make it work again.

No, they are just ready to fight.

"I'll demonstrate first." Kang Jiuliang held tweezers in his left hand and picked up the needle holder with his right hand, and said, "We are now called microscopic medical devices. Many students probably have never been exposed to them. Their characteristics are mainly small, such as the thickness of the suture we use now is only one-tenth of the human hair... This classmate, by the way, what are your name?"

"Ling Ran." Ling Ran replied.

"Don't like talking?"

"good."

"I will love to talk in the future. When surgeons undergo surgery, they are chatterboxes." Kang Jiuliang obviously changed his appearance during the operation and before the operation.

Ling Ran said "Oh".

Kang Jiuliang couldn't help but say, "Are you not curious about why?"

"Because you are bored." Ling Ran replied.

The interns laughed softly.

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

"It's because the surgeon was too bored when he had the surgery."

"Indeed, the surgery takes a long time and is really boring. We do a hand surgery, which often lasts ten or twenty hours. Even if you don't want to talk, the people around you want to talk too." Kang Jiuliang no longer struggled with Ling Ran's pun. He spoke and operated, as if the two did not interfere.

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 probably what it means.

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

The split tail connection of the white rat is ultimately a vascular anastomosis.

To suture the broken blood vessels together, six to eight stitches need to be sutured on the cross-section of the tiny blood vessels to ensure smooth blood flow, unhindered and leaking.

During the suture process, be careful not to produce cavity and dead cavity.

To talk about the skills of a surgeon, it is actually just about these specific and minor concerns.

For example, the hand surgeon can always be used after two or three years of training. However, whether it is used as usual after the operation, whether there are hidden pain or even complications, depends not only on the status of the mouse itself, but also on the surgeon's operation.

In short, it is difficult to stitch, and it is even more difficult to sew well.

"Do you know the stitching method I used?" Kang Jiuliang was bored and asked Ling Ran directly.

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

"Are you familiar?" Kang Jiuliang asked, but asked and answered himself: "It should be familiar. This is the most common and simplest stitching method, also called nodule suture, right? Just tie a knot with one stitch. When I was practicing in school, this is the one I practice most often. Where are you?"

"Absolutely." Ling Ran still answered concisely. He looked at Kang Jiuliang's operation, and his mind was filled with information, and he didn't want to chat at all.

"Okay, let's try it for you." Kang Jiuliang suddenly felt a little unhappy. Uncle, I'm very busy, okay, I've worked hard to demonstrate for you, so I can't even chat with you.

He originally wanted to do a few more anastomosis surgery to get familiar with Ling Ran, but now after he had a vascular anastomosis, he simply let go.

Ling Ran was stunned for a moment, but didn't think much about it. He said "Okay", and then grabbed the needle holder.

Kang Jiuliang's eyes never left the eyepiece, but at this moment he couldn't help but raise his head and glance at Ling Ran.

As the saying goes, experts can tell if there is any problem. For microsurgery, picking up the needle holder and not shaking your hands is the basics of getting started.

In order to suture 8 stitches on blood vessels with a diameter of 0.5 cm, the suture needles they used at this time were only one fifth of the thickness of their hair. When ordinary people pinched the needle holder, the tip of the needle at the front end would tremble constantly.

The amplitude is so large that it is like dancing under the microscope.

In fact, any doctor who has not specially practiced microsurgery will shake and will make people dizzy when they pick up the needle holder under the microscope. They have to hold it for a long time to practice.

Some doctors have to lift their arms and swollen in order to practice needles.

As for medical students...

Kang Jiuliang couldn't help but ask: "You Yunhua University Medical School, are you still practicing microsurgery now?"

"I run a small clinic at home." Ling Ran said the lies he made up, and the needle under the microscope went to the blood vessels in the tail of the white rat.

Kang Jiuliang quickly focused his attention, but saw the blood vessels in the tail of the mouse, which were not moving under the microscope.

Kang Jiuliang couldn't help but raise his eyebrows.

Under the microscope, the blood vessels did not tremble at all, which means they were not pulled 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 the foam to knot. The goal is that the foam cannot move at all.

It is also a broken finger that is sutured. If you do it at this level of suturing, the fingers will have a little stronger recovery ability and future functions.

In a trance, a stitching of the matching point was completed.

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

Thinking of this, Kang Jiuliang hurriedly went to see the vascular anastomosis under the microscope, and saw that the exposed knots maintained quite consistently. Judging from the appearance alone, it was pleasing to the eye, and there were no mistakes such as false knots.

This is textbook-style vascular suture and knotting, and there is no mistake at all.

Small clinic? Kang Jiuliang looked up at Ling Ran and thought to himself: How many fingers do you have to chop your small clinic to achieve such a suture level?
