Although it is called the one-handed knotting method, you still need to use both hands to operate it. The non-dominant hand pulls one end of the thread, and the dominant hand completes the knotting with one hand.
Gu Jun's dominant hand is his right hand. He holds the thread with his left hand and passes it through the two parallel red elastic cords of the model. His right hand takes the thread and lifts it up to start tying knots.
He concentrated his mind and recalled the process of Brother Qiang's knot tying just now. The level 2 calm hand allowed him to accurately 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 twist it in the opposite direction to make a square knot, then a triple knot...
He felt a sense of beauty, just like dancing. A single step may be just a strange posture, but when combined step by step, with strong intensity and rhythmic speed, it becomes a moving dance.
This change in intensity and rhythm made him intoxicated.
After finishing the one-handed knotting method, Gu Jun then started tying the two-handed knotting method, and then the instrument knotting method, reproducing all the demonstrations that Brother Qiang had just done, like a child who got a new toy, jumping happily
.
"Huh?" Zhou Jiaqiang couldn't help scratching the acne marks on his face. He walked over and hesitated several times, but did not interrupt Gu Jun.
The other four students around him were all looking at him, and Sun Yuheng felt a little frustrated. Gu Jun was learning so fast.
Wang Ruoxiang rolled her eyes and looked around, what's going on? It was like watching the replay of Brother Qiang's demonstration, it was exactly the same. Gu Jun knew how to attract stars?
As expected of Gu Jun, the sword rose and fell! Cai Zixuan and Jiang Banxia could only be convinced, no, the sword rose and fell!
Gu Jun was fully immersed in the model in front of him and continued to perform the deep knotting method, which was used for deep locations and important blood vessels.
He followed Brother Qiang's example and clamped one end of the line with the tip of the vascular forceps, went deep into the surgical field to cover the bleeding point, and then performed the knotting method with both hands. When tightening the knot, he used
Use the index finger of your right hand to slowly push the knot toward the ligation point, and hold it steady in the opposite direction with your left hand...
"Huh?" Zhou Jiaqiang was a little confused. He was even so proficient in deep knotting.
Seeing Gu Jun finish the operation and stop, Zhou Jiaqiang said: "Ajun, you played very well! Have you practiced before?"
"Uh..." Gu Juncai found that everyone was watching him like wolves and tigers. Maybe he would be less likely to be killed by them if he said he had practiced, but he still had many operational doubts that he wanted to ask Brother Qiang for advice, "I haven't practiced."
Yes, I learned it from you, Brother Qiang." He said.
"Okay." Zhou Jiaqiang had nothing to say. His superiors were right. He must train this boy hard!
Zhou Jiaqiang walked back to the podium and said: "Everyone has seen that Ajun's way of exerting force is correct. His whole body is in a relaxed state, making the sutures and fingers feel like a fish in water. Zixuan, half
Xia, your mistake just now was that you were too nervous; Ruoxiang, Yuheng, you are still holding your breath while operating. Everything is fine in the front, and it can be fine for a long time, but something can happen at any time, and you are still aware of it.
Less than.”
The basic structure of the sliding knot and the square knot are the same, that is, they are both composed of two single knots in opposite directions. Just because of improper operation, a knot with one line segment surrounding the other line segment twice is formed. This kind of knot is very easy.
It slips off, so it's called a slip knot.
“I tied a slip knot thinking it was a square knot, which eventually caused the injured person’s wound to burst and the bleeding to stop. This kind of disaster must be avoided at all costs.”
Everyone nodded immediately. No one wanted to make that kind of mistake. Relaxation is not that easy to do. Practice makes perfect.
"You guys continue to practice these three knots first." Zhou Jiaqiang said, looking at Gu Jun again, "Ajun, you come to learn surgical knots."
The surgical knot is also a basic knot. When tying the first single knot, the thread is wound twice. This can increase the contact surface between the threads, and then tie the second single knot to prevent it from slipping or loosening. Therefore, surgical knot
The knot is stronger, but also more time-consuming and difficult to operate.
Zhou Jiaqiang thought about how he could make it difficult for Gu Jun...
He only demonstrated it once, and Gu Jun learned it and seemed to copy it.
"Ajun, come and practice the false knot and slip knot again!"
The false knot is composed of two single knots with the same direction. It is easy to slip and should not be used in surgery. Therefore, the false knot and sliding are only used as negative teaching materials so that students can avoid making this mistake after they become proficient.
These two kinds of knots were naturally not difficult for Gu Jun. After a while, he became very familiar with them again...
Gu Jun felt a joy of learning. This kind of joy had not appeared for a long time. After a few years in college, he seemed to have lost this ability. Even the bad supplements he had taken some time ago were just bad supplements. But now, he has regained his ability.
Having tasted the joy of learning, he wanted to learn more and make himself better.
"Ajun, you change the catgut to operate it, and you also need to wear gloves!" Zhou Jiaqiang was still thinking about how to torment Gu Jun. This was a task assigned by his superiors.
What everyone currently uses in practice is silk thread, which is tougher and requires postoperative suture removal. Catgut is made of natural sheep intestines and can be absorbed by the human body, so there is no need to remove the sutures. However, sheep gut sutures
Gut is very brittle and breaks easily.
Moreover, wearing gloves and not wearing gloves are two different things. Medical rubber gloves are very tight when worn, which greatly affects the feel of the operation.
But in the actual operating room, the chief surgeon, anesthesia, first assistant, second assistant, third assistant... of course all need to wear gloves.
Can you be fierce this time? Zhou Jiaqiang thought to himself, catgut + gloves, even I can't guarantee 100% success in ligation!
"Okay." Gu Jun responded. He found disposable gloves from the table and put them on. His hands were immediately tightened. It usually took a few minutes to get used to it, but his hands could quickly switch muscle memory.
It has become a pattern of wearing gloves.
Picking up a piece of light yellow catgut from the string box, he rubbed it between his fingers, feeling its different textures, and fell into the beauty.
The ten fingers of both hands can operate naturally, one-handed techniques, two-handed techniques, instrument techniques... just like Brother Qiang said, it is as wonderful as a fish in water.
"..." Zhou Jiaqiang had to admit now that there is such a thing as talent in this world, and Gu Jun is the one who has many, many.
Having said that, this kid's spiritual intelligence is very high, right? He can enjoy it so much as a beginner, is he an A-? That's too high...
"Brother Qiang, what should we learn next?" As soon as Gu Jun completed all the catgut ligation operations, he looked at Brother Qiang eagerly.
"Uh..." Zhou Jiaqiang scratched his face. Gu Jun's look reminded him of his wife, who sometimes showed him this look at night.
Whether he was facing his wife at home in the past or facing Gu Jun now, Brother Qiang felt a little guilty.
