When the medical society classifies and classifies skills, the purpose is very clear.

Level 3 and above are just for use, just for being a clinician, and level 4 and above are another level.

For general surgeons, suturing to level 3, or even level 2, it is enough to go to clinical use, and there is no need to deliberately go deeper.

Therefore, in the early learning process, just to apply it skillfully to train, no matter how you use to achieve it, it is enough.

But to go to level 4, you have to be pure and extractive, or the medical society deliberately set up the step of refinement.

Fang Xian didn't delve into it, but after Zhou Xiyin operated 3 times in a row, and all of them reached the level 3 skill level on the skill training instrument, Fang Xian saw through some incoherent or mixed parts of Zhou Xiyin's operation process.

Fang Xian asked, "Senior Sister Zhou, have you understood the concept of level 4 skills in advance?" ”

"So in the process of practicing before, you have been deliberately moving closer to the concept of level 4 skills?"

Zhou Xiyin turned his head, hesitated, and nodded.

She can not receive many teacher resources, but there are a lot of objective resources, without teachers to teach, she can only take the level of objective standards benchmarked by the medical association to be self-taught.

"I also think so, the suturing operation can be divided into eight steps."

"The first step is to insert the needle, the second step is to pass the needle or thread the needle, the third step is to exit the needle, the fourth step is to press the thread, the fifth step is to tie the first knot, the sixth step is the second knot, the seventh step is to cut the thread, and the eighth step is to take the thread."

"In these steps, the first five steps are the process of operation, and the last three steps are actually a concept of overall stitching, which pays attention to integrity."

"In the first few steps, you will hesitate to think about whether you can do without stitches, and when you take the next few steps, you will think that you can't reach the level of stitch-free, so you will rely on the two concepts of [level] or [fitting]."

"So you are now, a stitch, will be relatively nondescript."

"Level 4 suture, the simplest and most simple way to suture is actually alignment, of course, you can also directly cross the alignment and level, directly to the delicate aspect of ......"

"However, in the process of operation, you need to have no distractions, especially in the process of knotting and rewinding, don't think about stitch-free and other conceptual things, just go in one direction."

"Let's honestly rely on the concept of [alignment] first, and the same is true in the overall operation of the final reel. The bad thing about the concept of [Match] is that it is not good enough compared to other concepts, and it is not that it is not good enough compared to the level 3 skills mixed with all the level 4 skills. ”

"Do you understand that?" Fang Xian saw the problem, explained the pros and cons like this, and said how to do it.

Zhou Xiyin nodded.

Then continue the exercise.

After suturing it a few more times, Fang Xian said again: "At the beginning, it is indeed not easy to throw away the existing cognition, and even need to be rigid, but you can divert your attention, that is, to bring your mind closer to the local anatomy of this position, why is it so aligned, why the local suture of this position, why can't it be accurately aligned, and what are the disadvantages." ”

"This kind of distraction may help you improve your concentration and forget about the mixture of other theories in the process of operation, so as to avoid ...... of gains and losses."

After Fang Xian finished speaking, he was a little sluggish.

It seems that the level 5 suture surgery has brought me not only the improvement of the operation level, but also more hidden benefits, including some theories of basic suture, which are included, but I have not experienced it deeply and meticulously.

Zhou Xiyin nodded and asked rhetorically: "So I need to look at some more theoretical knowledge related to suturing and replace 'absolute left and right looking' with 'relative left and right hope'?" ”

Fang Xian's eyelids tightened when he heard this-

To be honest, he can't fully understand some of the professional terms and pronouns that Zhou Xiyin said.

But the good thing is that the meaning is the same.

"That's pretty much it! Instead of thinking about other ideas in the process of suturing, it is better to think about the corresponding theories of simple basic anatomy in the process of suturing, so as not to be affected. ”

"If you want to achieve a light weightlift, unless you jump directly from level 3 to level 5 of suture, it will be difficult to get to level 4, which will be nondescript." Fang Xian explained in his own words.

is also pondering Zhou Xiyin's so-called learning concept, which is more professional than looking left and right and absolute left and right.

"Okay, senior brother!" Zhou Xiyin got the route to learn, so she knew what to do next.

Zhou Xiyin continued to stitch up.

"This stitch is too deep, and now you think of stitchless again, and you think of a suture that reinforces the subcutaneous layer." Fang Xian began to instruct and persuade.

"The span of this needle is too large, although the hierarchical suture pays attention to freedom and speed, but when you don't have to pay attention to speed, you don't need to pay attention to the speed of suturing."

"The speed of suturing is meaningful in the application process, and there are special scene conditions, that is, in the process of first aid and rescue, rapid suturing is required. And most patients, with ordinary speed suturing, will not affect them. ”

"The more patients you have to contact, all you need is plain sutures."

“……”

Zhou Xiyin has been silent, slowly understanding, and slowly correcting.

The clock quickly ticked to ten o'clock.

Zhou Xiyin didn't say that there was no special growth, but the degree of growth was not large, and she still couldn't achieve absolute concentration, because she knew too many things, and she always suffered from gains and losses.

But there is also growth, at least she can deliberately maintain concentration, and after realizing that her thinking is messy, she knows how to correct it in time.

"Let's go here today, you can go back and read the book again, mainly focusing on the fat layer and subcutaneous sutures, which are about the requirements in different areas." Fang Xian began to take off his gloves.

He felt that what Zhou Xiyin needed in the next step was digestion and pondering, not simple mechanical repetition.

Zhou Xiyin also took two steps back and turned his head: "Okay, senior brother." Thank you for your hard work. ”

"Well, take your time, don't rush it."

"Your foundation for suturing operations is very good, and the basic skills are also solid, the next thing to do is to refine your own operations."

"It's better to decorate yourself with ideas excessively, and simple decorations are more beautiful." Fang Xian once again side-cited an example.

Zhou Xiyin pursed her lips, took off her gloves and temporarily took off her mask, revealing her delicate face, and said hesitantly: "In other words, in fact, if you are ignorant in advance, the easier it is to move forward." ”

"That's right! ~" Fang Xian nodded.

Zhou Xiyin's heart became bitter, everyone has always taught her to make her more mature, and no one has ever made her very pure and naïve, how can this be done?
