Chapter 45

Although it is called single handed knot tying method, it still needs two hands to operate. The non-profit hand pulls one end of the thread, and the hand with one hand completes the knot.

Gu Jun's right hand is his right hand. His left hand holds the line and goes through the bottom of the two red parallel elastic cables of the model. His right hand picks up the line and starts to tie the knot.

He kept his mind in mind and recalled the process of brother Qiang's knotting just now. The second level calm hand allowed him to accurately control his hand nerves. According to the rhythm and gesture steps, his right hand finger steadily and gently tied a single knot, and then turned it into a square knot and then a triple knot

He felt a sense of beauty, just like dancing. Taking a single step out may be just a strange gesture, but when combined step by step, with the weight of strength and the tempo, it becomes a moving dance.

This change of strength and rhythm made him indulge in it.

After finishing the one handed knotting method, Gu Jun then started to use both hands knotting method, and then the equipment knotting method. He reproduced all the demonstration of brother Qiang just now, just like a child with a new toy, jumping happily.

"Well?" Zhou Jiaqiang couldn't help scratching the pockmarks on his face and walked over. He tried to stop talking several times, but he didn't interrupt Gu Jun.

Around the other four students are all in sight, sun Yuheng is a little frustrated, Gu Jun learn so fast.

Wang Ruoxiang turns to slip an eye to see right and left, how to return a responsibility? It's as like as two peas show the replay of strong brother's demonstration. It's the same as Gu Jun.

It's Gu Jun who is worthy of it! Cai Zixuan and Jiang Banxia only have to accept Qi. No, their hands are up and down!

Gu Jun has been fully involved in the model in front of his eyes, and continues to carry out the deep knot method, which is used for the operation of deep position and important blood vessels.

He followed the example of brother qiangge. He clamped one end of the thread with the tip of the vascular forceps, went deep into the surgical field, caught the tip of the forceps at the bleeding point, and then operated according to the method of tying his hands. When tightening the knot, he slowly pushes the knot to the ligation point with the index finger of his right hand, and stabilizes it in the opposite direction with his left hand

"Eh?" Zhou Jiaqiang is about to break the pockmarks. He is so skilled in deep knotting.

At this time, seeing Gu Jun finish the operation and stop, Zhou Jiaqiang said: "ah Jun, you played very well! Have you practiced before

"Er..." Gu Juncai found that people were watching him like a wolf. Maybe he said that he had practiced, and it was not easy to be killed by them. But he still had a lot of operational doubts to ask brother Qiang, "I didn't practice. I learned from brother Qiang." He said.

"All right." Zhou Jiaqiang has nothing to say. He is right. He must practice this boy hard!

As Zhou Jiaqiang walked back to the platform, he said: "as you can see, ah Jun's way of exerting force is the right one. He is in a relaxed state, making stitches and fingers seem like fish in water. Zixuan and Banxia, the mistake you made just now is that you are too tense. Ruoxiang and Yuheng, you still hold your breath to operate. There is nothing in front of you, and you can be OK for a long time, but you can also have an accident at any time, and you are not aware of it. "

The basic structure of the sliding knot and the square knot is the same, that is, they are composed of two opposite single knots. Only because of improper operation, a knot formed by two circles of one line segment around the other line segment is formed. This kind of knot is easy to slip off, so it is called sliding knot.

"He made a slippery knot and thought it was a square knot, which eventually caused the wound to burst and stop bleeding after the operation. We must try our best to avoid such intrusions. "

Everyone immediately nodded. No one wanted to make such a mistake. It's not easy to relax, but practice makes perfect.

"You go on practicing these three knots first." Zhou Jiaqiang said, his eyes again aimed at Gu Jun, "ah Jun, you come to learn surgical knot."

Surgical knot is also a kind of basic knot. When the first single knot is made, the thread will be wound twice in a row. In this way, the contact surface between wires can be increased. If the second knot is made, it will not be easy to slip or loosen. So the surgical knot is stronger, but it is also more time-consuming and difficult to operate.

Zhou Jiaqiang thought that it would be difficult to get Gu Jun for a while

He just demonstrated once, and Gu Jun learned it. It was like copying the past.

"Ah Jun, come and practice fake knots and sliding knots again!"

The false knot is composed of two single knots with the same direction, which is easy to slip off and is also avoided in operation. Therefore, false knot and slide are only used as negative teaching materials, so that students can avoid making such mistakes after they are proficient.

These two kinds of knots are naturally difficult to Gu Jun, and after a while, they are very familiar with each other

Gu Jun felt a joy of learning. This joy has not appeared for a long time. He seems to have lost this ability after spending several years in the University. Even if the evil remedy he made some time ago, it was just a bad remedy. But now, he relishes the joy of learning. He wants to learn more and make himself better.

"Ah Jun, you change catgut to operate, oh, and wear gloves!" Zhou Jiaqiang is still thinking about how to deal with Gu Jun, which is a task handed down by the superior.

We are now practicing with silk thread, which is more tenacious. If it is used in surgery, we need to remove the thread after operation. The catgut is made of natural sheep intestines, which can be absorbed by the human body, so there is no need to remove the thread. However, the catgut is very brittle and easy to break.And wearing gloves and not wearing gloves are two things, medical rubber gloves are very tight, very affect the feel of the operation.

But in the actual operating room, the main knife, anesthesia, first aid, second aid, third aid Of course, gloves are needed.

Can you be fierce this time? Zhou Jiaqiang thought, catgut + gloves, even I can not guarantee 100% ligation success!

"OK." Gu Jun should sound, from the belly of the table to find disposable gloves to wear, his hands suddenly tight, generally need a few minutes to adapt, but his hands can quickly switch muscle memory, changed to wear gloves mode.

He picked up a piece of light yellow catgut from the wire box, rubbed it between his fingers, felt its different texture, and sank into the beauty.

The ten fingers of both hands naturally operate, single manipulation, double manipulation, instrument method It's as wonderful as brother Qiang said.

“……” Zhou Jiaqiang has to admit that there are indeed talents in this world. Gu Jun has a lot of them.

Anyway, this kid's got a lot of insight, right? It's a -? That's too high

"Brother Qiang, what are we going to learn next?" As soon as Gu Jun finished all the ligation operations of catgut, he looked at brother Qiang eagerly.

"Er..." Zhou Jiaqiang scratched his face. Gu Jun's eyes made him think of his wife. Sometimes he showed his eyes to him at night.

Whether it was in the past at home facing his wife, or now facing Gu Jun, strong brother's heart is a bit empty.
