Although it is called the one-handed knotting method, it still needs to be operated with both hands. The non-skilled hand pulls one end of the thread, and the good hand completes the knotting with one hand.
Gu Jun's sharp hand is his right hand. With his left hand, he first passed the thread under the two red parallel elastic strips of the model, and his right hand took the thread and lifted it up to start knotting.
He concentrated his mind, recalling the process of Brother Qiang's knotting 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 stroke steadily and gently. knot, then twisted in reverse to make a square knot, then a triple knot...
He feels a sense of beauty, just like dancing. A single step may be just a strange posture, but when combined step by step, with strong strength and rhythm, it becomes a moving dance.
This change in strength and rhythm made him intoxicated.
After finishing the one-handed knotting method, Gu Jun continued to play the two-handed knotting method, and then the instrumental knotting method, reproducing all the demonstrations of Brother Qiang just now, like a child who got a new toy, jumping happily .
"Huh?" Zhou Jiaqiang couldn't help scratching the pimple marks on his face, and walked over, hesitant to speak several times, but he didn't interrupt Gu Jun.
The other four students around were all watching, and Sun Yuheng felt 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 replay of Brother Qiang's demonstration, it's exactly the same, Gu Jun knows how to attract stars
As expected of Gu Jun, he raised his sword and dropped it! Cai Zixuan and Jiang Banxia can only be convinced, no, their hands are up and down!
Gu Jun has already devoted all his attention to the model in front of him, and continues to perform the deep knotting method, which is used for deeper positions and important blood vessels.
Like Brother Qiang, he clamped one end of the thread with the tip of the vascular forceps, went deep into the operative field to catch the tip of the forceps that clamped the bleeding point, and then performed the operation by using the method of knotting with both hands. When tightening the knot, he used the index finger of his right hand to slowly push the knot towards the tie point, and stabilized it with his left hand in the opposite direction...
"Eh?" Zhou Jiaqiang was a little stunned, he was so proficient at deep knotting.
At this time, seeing Gu Jun finished the operation and stopped, Zhou Jiaqiang said: "Ah Jun, you play very well! Have you practiced before?"
"Uh..." Gu Juncai noticed that the crowd was watching him like a wolf. Maybe he said that he had practiced before so that he would not be killed by them, but he still had a lot of doubts about the operation and he wanted to ask Brother Qiang for advice, "I haven't practiced , I learned from you, Brother Qiang." He said.
"Okay." Zhou Jiaqiang had nothing to say, his boss was right, he had to train this kid hard!
Zhou Jiaqiang walked back to the podium and said: "As you can see, Ah Jun's way of exerting force is correct. He is in a relaxed state, making the sutures and fingers feel like ducks in water. Zixuan, Ban Xia, your mistake just now was that you were too nervous; Ruoxiang and Yuheng, you are still holding your breath and operating. There is nothing wrong in front of you, and you can be fine for a long time, but you can also have accidents at any time, and you are still aware of it. not."
The basic structure of the sliding knot and the square knot is the same, that is, both are composed of two single knots in opposite directions. Just because of improper operation, a knot in which one line segment wraps around the other line segment twice is formed. This kind of line knot is easy to slip off, so it is called a slip knot.
"I tied a slippery knot and thought it was a square knot. In the end, the wound burst after the operation and the bleeding could not be stopped. Such a disaster must be avoided as much as possible."
Everyone nodded immediately, no one wanted to make such a mistake, but relaxing is not so easy, it still needs practice to make perfect.
"You guys continue to practice these three kinds of knots first." Zhou Jiaqiang said, and looked at Gu Jun again, "Ah Jun, come and learn the surgical knots."
The surgical knot is also a basic knot. When the first single knot is tied, the thread is wound twice. This can increase the contact surface between the thread and the thread, and the second single knot is not easy to slip or loosen. So the surgical knot is stronger, but also more time-consuming and difficult to manipulate.
Zhou Jiaqiang thought that he could make it difficult for Gu Jun...
He just demonstrated it once, and Gu Jun learned it, as if copying the past.
"Ajun, come and practice false knots and slip knots again!"
False knots are composed of two single knots in the same direction, which are easy to slip and should not be used during surgery. Therefore, false knots and sliding only exist as negative teaching materials, so that students can avoid making such mistakes after they are proficient.
These two kinds of knots are naturally not difficult for Gu Jun, and after a while, they are very familiar again...
Gu Jun felt the joy of learning, this kind of joy has not appeared for a long time, he seems to have lost this ability after a few years in the university, even if the bad luck some time ago was just bad luck. But now, he has regained the joy of learning, and he wants to learn more and make himself better.
"Ah Jun, you need to change guts to operate, oh, you need to wear gloves!" Zhou Jiaqiang is still thinking about how to torment Gu Jun, this is a task assigned by his superiors.
Everyone is currently practicing with silk thread, which is tougher, and it needs to be removed after surgery when it is used in surgery. The sheep catgut is made of natural sheep gut, which can be absorbed by the human body, so there is no need to remove the stitches, but the sheep catgut is very brittle and easily broken.
Moreover, wearing gloves and not wearing gloves are two different things. Medical rubber gloves are very tight, which affects the feel of operation.
But in the actual operating room, the chief surgeon, anesthesia, first aid, second aid, third aid... Of course, you need to wear gloves.
Can you still be fierce this time? Zhou Jiaqiang thought, catgut + gloves, even I cannot guarantee a 100% ligation success!
"Okay." Gu Jun responded, and found a disposable glove from the belly of the table and put it on. His hands tightened immediately. It usually takes a few minutes to get used to it, but his hands can quickly switch muscle memory. Became a gloved pattern.
Picking up a piece of pale yellow gut from the thread box, he rubbed it between his fingers to feel its different textures, and sank into the beauty again.
The ten fingers of both hands operate naturally, one-handed, two-handed, instrumental... just like what Brother Qiang said is as wonderful as a fish in water.
"..." Zhou Jiaqiang had to admit now that there are indeed such things as talent in this world, and Gu Jun has many, many of them.
Having said that, this kid is very intelligent, right? You can enjoy it like this for beginners, isn't it A-? That's too high...
"Brother Qiang, what shall we learn next?" Gu Jun looked at Brother Qiang longingly as soon as he finished ligating all the catgut.
"Uh..." Zhou Jiaqiang scratched his face, Gu Jun's eyes reminded him of his wife, who sometimes showed him such eyes at night.
Whether it was facing his wife at home in the past, or facing Gu Jun now, Brother Qiang felt a little guilty.
