Surgery, why sutures are needed? Many people may not have considered this issue now.

Just take it for granted that after surgery, there are incisions, and of course they need to be sutured.

But this is compared to other surgeons.

In the Department of Orthopedic Traumatology, there is a saying called blade-thickness skin grafting, which is suitable for skin grafting after extensive superficial epidermal injuries.

This kind of surgery does not require sutures. It only requires pressure bandaging.

Thick skin is thinner than potato skin. The reason why it can grow is because the skin and subcutaneous tissue are well aligned, and the skin itself has a strong ability to regenerate itself.

Generally, in addition to blade-thickness skin grafting, suturing is required whether it is a flap or a full-thickness skin graft.

This is common knowledge in surgery. Even arthroscopic surgery requires suturing.

But it seems that now that Professor Min saw the effect of Lu Cheng's suture, he suddenly combined it with the concept of blade-thickness skin grafting, which he had not done for a long time, and the idea of ​​suture-free cosmetic wounds that had been mentioned in the burn department.

Looking at this wound, Professor Min felt that its subcutaneous parts were almost completely aligned, there were no steps in the skin, and there were no inversions or large gaps, which was completely consistent with the fact that the skin could heal itself.

If so, a double-pull puller can be added to the outside. Even if the outermost layer is not sutured, the wound can still grow.

Although in theory, this is the case.

But can such a wound be sewn by a doctor who looks so small?

Even after seeing it with his own eyes, Professor Min still raised doubts.

Everyone else turned to look at Lu Cheng almost at the same time, including the hand-washing nurse.

Handwashing nurses do not only specialize in handwashing for one department or one professor. They also need to be on duty, so they will encounter all possible surgeries in other departments. Therefore, she has seen many surgeries and followed surgeries from too many departments.

But it seems that so far, she has not seen this situation before.

And given her professional field, she couldn't find a suitable reason to explain it.

Lu Cheng saw everyone looking at him and felt a little nervous. However, because he had learned from Professor Zhou Xuanqing, Lu Cheng was not afraid. He recalled the suturing techniques and principles again, but still found nothing.

mistake.

Professor Min turned to look at Lin Hui, still a little unsure and asked: "Lin Hui, you have done a lot of scientific research. In recent articles, you have seen about the effect of suturing wounds, or something like that."

Special suturing method?”

Professor Min tried his best to find things from existing things to avoid being ignorant.

As Lin Hui, who has the deepest level of scientific research and has the broadest exposure to scientific research, is naturally the best person to ask. Even he is still slightly inferior to Lin Hui in the field of scientific research. It is just that he is two years older than Lin Hui clinically.

Over ten years, experience and knowledge are overwhelming.

Lin Hui shook his head: "Since the emergence of cosmetic sutures, so far, except for a skin tension reducer, there has been no further research on wound suturing."

"The main reason is that it's too difficult."

"There are speculations and hypotheses, but most people don't take them seriously, and few people actually test them. After all, the risk of failure is still quite high."

Suturing is very simple, so simple that almost any doctor can do it.

But just because it is simple and easy to promote, its improvement is particularly difficult.

Of course Lin Hui could see that the effect of Lu Cheng's subcutaneous suturing was no worse than that of cosmetic suturing, and there were no knots. Moreover, even cosmetic suturing would produce certain steps during the suturing process.

This results in small scars during the postoperative recovery process.

Since there is currently no introduction to this suture method, Lin Hui is more curious about the current surgical incision and how Lu Cheng sutured it.

Lin Hui then asked Lu Cheng: "Lu Cheng, what were you thinking when you just sewed?"

Since Lu Cheng can sew, of course he won't talk nonsense about his good condition.

Putting down the needle pliers and thread in his hands, he explained in detail: "Teacher Min, Teacher Lin, Teacher Zhu, it's like this."

"When Professor Min was doing the surgical approach just now, I saw that Professor Min went through the following levels."

"Skin, superficial fascia, fat layer and deep fascial layer."

"Because these layers have a certain elastic modulus, after Teacher Lin and you have completed the suturing of the subcutaneous joint capsule and the femur, I try not to cause traction, so that there will be no steps."

"Moreover, when Professor Min performed the operation, he only made one cut in the skin layer, leaving the edges intact and smooth. Although the superficial fascia layer and fat layer were treated with an electric knife..."

"According to the introduction of local anatomy and orthopedic anatomy, the fat layer on the outside of our femur is thicker, so we can try to restore the unevenness of the suture under the fat layer in this layer. As long as the pulling force is not too large, the fat will liquefy

There’s less risk, too.”

"Combined with Professor Min's approach, my idea is to restore their original appearance as much as possible, so when inserting the needle, try to be perpendicular to the incision of each layer of the wound, and when suturing the uppermost layer, try to start from the subcutaneous dermis.

Insert the needle into the lower layer.”

"Hide the knots downward so that the smoothest possible result can be achieved when suturing the skin."

"Now it seems that the effect is not bad."

Lu Cheng did not use the metaphysical explanation of being in good condition, and both Lin Hui and Professor Min suddenly began to think deeply.

But contemplation is contemplation. Even Professor Min himself could not remember which layer he made in which directions and how many cuts he made when making the approach.

Lu Cheng's explanations are all theoretical based on the analysis of existing basic knowledge, and he also applies them to practical operations.

It is so well-founded that even if one is dissatisfied, one cannot have any doubts.

It's just that Lu Cheng's lecturing ability was a bit inferior. Not to mention Ji Mo and the others, even Lin Hui and others were confused!

Professor Min thought for about ten seconds and asked Lin Hui: "If we compare this suture method with our own suture method, how long will it take?"

Professor Min is asking about the topic.

It's promising, but no one can do it. Someone in your own group can do it. Blind comparison is a clinical issue.

Lin Hui said: "Professor Min, are you saying that in the future, this suture method will not sew the outermost layer, which can save money on beauty threads and achieve such results?"

"Yeah." Professor Min nodded.

"According to the current clinical research data, there are basically 20 to 40 groups of controls."

"However, the results of skin sutures come quickly, and the stitches can be removed in about fourteen days."

"And as long as there are no problems during the process, there will be relatively few postoperative complications."

"In terms of time, at most three months, our team can produce enough clinical data. Of course, before that, it must be reported to the hospital and approved by the Ethics Society." Lin Hui is indeed someone who is very familiar with scientific research.

, replied very familiarly.

"If you run these, it will probably take a long time."

When he said this, Lin Hui wanted to shave off all the hair he had that wasn't much in the first place.

Professor Min, this Lu Cheng is actually not from our family!

It was temporarily borrowed from the emergency department. We can't take him with him for this clinical subject.

"If you need to run something, run it. Once it's done, we'll do it again. These programs must not be messed up." Professor Min's own scientific research level is naturally not bad, and such low-level mistakes will not occur.

"Wash your hands and get another thread for Xiao Lu."

"It's a pity that without the approval of the Ethics Society, the latest batch of patients will not be able to enjoy this new method of suturing that is both economical and beautiful." Professor Min said with a little pity.

Lin Hui felt even more miserable and almost cried.

He really wanted to kick Lu Cheng out of the clinic and forget it once and for all!

What should we do about this matter?
Chapter completed!
