Although it is called the one-handed knot method, it is still necessary to use both hands to operate, and the non-sharp hand pulls the end of the thread, and the sharp hand completes the knot with one hand.

Gu Jun's sharp hand is his right hand, he holds the thread in his left hand and passes it under the two red parallel elastic strips of the model first, and his right hand takes the thread and lifts it and begins to tie the knot.

He stared at his mind, thinking back to the process of Brother Qiang's knot just now, the second-level calm hand allowed him to precisely control the nerves of his hand, according to the rhythm and gesture steps, the fingers of his right hand made a single knot steadily and gently, and then reversed to tie a square knot, and then a triple knot......

He felt a sense of beauty, like dancing, a single step might just be a strange gesture, but when the steps are combined, there is the weight of the strength, the speed of the beat, and it becomes a moving dance.

This change in strength and tempo made him intoxicated.

After finishing the one-handed knotting method, Gu Jun then started the two-handed knotting method, and then the instrument knotting method, reproducing all the demonstrations that Brother Qiang had just demonstrated, like a child who had gotten a new toy, jumping happily.

"Huh?" Zhou Jiaqiang couldn't help scratching the acne marks on his face, walked over, and stopped talking several times, but he didn't interrupt Gu Jun.

The other four students around were all looking at him, and Sun Yuheng was a little frustrated, Gu Jun learned so fast.

Wang Ruoxiang rolled her eyes to look left and right, what's going on? It's like watching the playback of Brother Qiang's demonstration, it's exactly the same, Gu Jun knows how to absorb stars?

It is worthy of Gu Jun, his hand is up and down! Cai Zixuan and Jiang Banxia can only be convinced, no, hands up and down!

Gu Jun was already fully engaged in the model in front of him, and continued to perform the deep knotting method, which is used for deep positions and important blood vessels.

He followed Brother Qiang's example to clamp one end of the thread with the tip of the vascular forceps, went deep into the surgical field to cover the tip of the forceps at the bleeding point, and then operated according to the method of tying knots with both hands. When tightening the knot, he uses the index finger of his right hand to slowly push the knot towards the ligature point, and his left hand is steady in the opposite direction......

"Huh?" Zhou Jiaqiang was a little stunned, even the deep knotting method was so proficient.

At this time, seeing that Gu Jun had completed the operation and stopped, Zhou Jiaqiang said, "Ah Jun, you played very well!" Have you practiced before? ”

"Uh......" Gu Juncai found that everyone was watching him like wolves, maybe he said that he had practiced and was not easy to be killed by them, but he still had a lot of operational doubts to ask Brother Qiang for advice, "I haven't practiced, I just learned from Brother Qiang." He said.

"Okay." Zhou Jiaqiang has nothing to say, the boss is right, he must train this kid fiercely!

Zhou Jiaqiang walked back to the podium and said: "Everyone can see that Ah Jun's way of exerting force is correct, and his whole person is in a relaxed state, making the stitches and fingers seem to be like a fish in water." Zixuan, Banxia, your mistake just now is that you were too nervous; Ruoxiang, Yuheng, you are still holding your breath and operating, the front is fine, and you can be fine for a long time, but you can also have an accident at any time, and you can't notice it. ”

The basic structure of the sliding knot and the square knot is the same, that is, they are both composed of two single knots in opposite directions. Just because of improper operation, a knot with one side of the line segment around the other line segment is formed twice, and this kind of line knot is easy to slip off, so it is called a slip knot.

"I thought it was a square knot when I made a slippery knot, and finally caused the wound to burst after the operation and couldn't stop the bleeding. Such a scourge must be avoided as much as possible. ”

Everyone nodded suddenly, no one wants to make such a mistake, but relaxation is not so easy to do, and practice makes perfect.

"You go ahead and practice these three knots." Zhou Jiaqiang said, his eyes turned to Gu Jun again, "Ah Jun, you come to learn surgical knots." ”

The surgical knot is also a basic knot, which is to tie the first single knot when the line is wound twice, so as to increase the contact surface between the line, and then the second single knot is not easy to slip or loosen. So the surgical knot is stronger, but it is also more time-consuming and difficult to handle.

Zhou Jiaqiang thought about how he could make it difficult for Gu Jun......

He only demonstrated it once, and Gu Jun learned it, as if copying the past.

"Ah Jun, let's practice fake knots and slip knots again!"

False knots consist of two single knots in the same direction, which can be easily slipped, and are also contraindicated during surgery. Therefore, false knots and sliding only exist as negative teaching materials, so that students can avoid making such mistakes after they become proficient.

These two knots are naturally difficult for Gu Jun, and after a while, they are very familiar with it again......

Gu Jun felt a joy of learning, this joy had not appeared for a long time, and after a few years in college, he seemed to have lost this ability, even if the evil supplement some time ago was just a bad supplement. But now, he has regained the joy of learning, and he wants to learn more and make himself better.

"Ah Jun, you change the sheep intestine to operate, oh and wear gloves!" Zhou Jiaqiang is still thinking about how to toss Gu Jun, this is a task handed over from above.

Everyone is practicing with silk threads, which are more tenacious, and they need to be removed after surgery when they are used in surgery. The sheep intestine is made of natural sheep intestines, which can be absorbed by the human body, so there is no need to remove the sutures, but the sheep intestines are very brittle and very easy to break.

And wearing gloves and not wearing gloves are two different things, medical rubber gloves are very tight to wear, which affects the feel of operation.

But in the actual operating room, the chief surgeon, anesthesia, first assistant, second assistant, third assistant...... Of course, gloves are required.

Can you still be fierce this time? Zhou Jiaqiang thought to himself, sheep intestine + gloves, even I can't guarantee 100% successful ligation!

"Okay." Gu Jun responded, flipped through the belly of the table and found disposable gloves to put on, his hands suddenly tightened, it usually takes a few minutes to get used to it, but his hands can quickly switch muscle memory and change to the mode of wearing gloves.

Picking up a pale yellow sheep gut from the wire box, he rubbed his fingers to feel its different texture, and then sank into the beauty.

The ten fingers of both hands operate naturally, single-handed, two-handed, and instrumental...... Just like Brother Qiang said, it is as wonderful as a fish in water.

"......" Zhou Jiaqiang has to admit that there is indeed such a thing as talent in this world, and Gu Jun has many, many of them.

Then again, this kid is very intellectual, right? Beginners can enjoy it like this, is it A-? That's too high, isn't it......

"Brother Qiang, what are we going to learn next?" As soon as Gu Jun completed all the ligation operations of the sheep intestines, he looked at Brother Qiang with a blank eye.

"Uh......" Zhou Jiaqiang scratched his face, Gu Jun's eyes reminded him of his wife, and sometimes showed him this kind of look at night.

Whether he was facing his wife at home in the past, or facing Gu Jun now, Brother Qiang felt a little empty in his heart.
