Killing a sheep is not as good looking as killing a pig.

Liu Xuande slaughtered the sheep and peeled off the skin skillfully.

When I was buying supplies, I was given a pair of pig-killing hooks. I bought them at that time, but I'm using them now.

Hanging the sheep on an iron hook makes it very convenient to separate the meat and peel the skin.

At this time, I don’t know whether Liu Xuande admired Li Mengxi’s foresight.

Sheep offal, tripe intestines, etc. were thrown casually into a basket.

Li Mengxi went over to take a look.

Liu Bei was cutting the meat with a knife and watching Li Mengxi pull out his intestines. Liu Bei laughed and said, "Xi'er, we eat meat and the intestines don't care about him!"

Li Mengxi didn't even raise his head, "I use sheep intestines, not for food."

"It's used to twist the intestines into thread and sew the wounds."

When Li Mengxi said this, Liu Bei became interested.

How to sew the intestines into a thread, and what is the so-called suturing of wounds?

Liu Bei didn't care about the sheep anymore. He handed the knife to the soldiers on the side and asked the soldiers to divide the remaining mutton.

When he picked up the sheep intestines, they were soft and slippery. Li Mengxi felt disgusted and disgusted.

However, it is important to save people.

Holding back his nausea, Li Mengxi cut off a section of sheep intestines and asked for water to wash the intestines.

There is no water nearby, only in the city there is a well.

Li Mengxi then carried his intestines and went back to the city with Liu Bei.

Pour water and wash the intestines until the intestines are clean.

Next, it’s time to rub the gut.

But Li Mengxi discovered something unexpected.

Damn it, sheep intestines seem to have different structures, several parts.

Li Mengxi used his hand to tear the outside of the intestines, tearing up a white film-like substance.

Not only is there this white membrane inside, but there is also a layer inside and outside the intestines.

The one in the middle is the main body of the intestines.

this……

Li Mengxi was at a loss.

After all, which part of the legendary catgut is made from?

By the well, Li Mengxi was at a loss for a while.

He was searching for knowledge about catgut.

It seems that catgut is absorbed by the human body because its main component is collagen.

So, what is collagen?!

Does it mean the middle layer? Or the two layers of white film-like things inside and outside?

Li Mengxi thought for a long time and came up with a good idea.

Now, I don’t know which part of the intestine contains collagen, or whether the inner, middle and outer layers can be used to make catgut, or perhaps only the outer two film-like layers can be used to make catgut.

Don't know any of this.

So, assuming the first situation, all three layers of the intestine can be used to make catgut. Then, separate the three layers and twist them into threads.

Only use the thin film on the outside of the intestines and twist it into a thread.

Then use the middle layer and twist the thread separately.

Then take one layer from the intestine and roll the thread separately.

In this way, there are three different types of gut. If all sheep intestines are composed of collagen, then these three types of gut can be used to suture wounds.

And if the collagen-rich structure refers to the transparent film wrapped outside the intestines of sheep, then if each part is separated and twisted independently, there can also be a genuine sheep intestine that is suitable for medical use.

That's the meaning.

When you don’t know the more detailed production details of catgut, you can make catgut by separating the various structures of the catgut.

After Li Mengxi figured it out, he started to tear off the white film on the outside of the intestines with his hands.

Liu Bei didn't understand why and looked at it with interest.

Wait until the intestinal membrane is torn off.

Li Mengxi began to prepare the thread.

But his hands-on skills were very poor. After rubbing it clumsily for a long time, the large piece of intestinal membrane still couldn't be kneaded into a thread.

Liu Bei looked at it for a long time and finally couldn't help but speak.

"Xi'er, do you want to make this thing thinner and make it into a thread?" Liu Bei asked tentatively.

"Yeah!" Li Mengxi wiped the sweat from the tip of his nose. He looked at Liu Bei and wondered if Liu Bei had any good ideas.

Liu Bei rolled up his sleeves and took action himself.

"What a force." Liu Bei bent down and picked up the intestinal membrane that Li Mengxi had torn. He used his nails to break it open and tear it into thinner strips. "Wouldn't it be easier if you break it into thin strips and then rub the rope?"

Li Mengxi suddenly realized.

Well, this way you can tear the large piece of intestinal membrane into very thin strips, and then you can easily twist the thread.

Otherwise, even if it can be twisted into a thread with a diameter as large as a sheep intestine without tearing it apart, wouldn't the thread be as thick as chopsticks?

If the suture thread is so thick, it will be impossible to sew the wound.

Finally, when the rebels in the city had been cleared, Li Mengxi and Liu Bei worked together to pull out three catguts.

Among them, there is one thread made of the outer membrane of the sheep intestine, one thread made of the inner membrane of the sheep intestine, and one thread made of the intestine itself, which is thick and ugly.

Haven't used it yet, haven't tested it yet.

But based on his feeling, Li Mengxi vaguely felt that catgut should refer to a line made of intestinal membrane.

You see, the lines between the inner and outer intestinal membranes are thin, white and strong. The lines between the intestines are so ugly, simply ugly.

The thread was finished, Liu Bei asked, is it done?

Li Mengxi is about to say it.

Then I saw Liu Bei's big dark hands, with mud still hidden in his fingernails.

Li Mengxi suddenly remembered that Liu Bei had just used his nails to tear the intestinal membrane into strips.

Forgot an important step!

Li Mengxi slapped his head.

This needs to be sterilized! The production process needs to be sterile! If the catgut is sewn into the wound without disinfection, and if you rub the catgut with dirty hands, the wound will definitely become infected.

Therefore, it was useless for Liu Bei to say hello.

"No, I have to soak it in wine." Li Mengxi said.

Regarding disinfection, fortunately, the military has high-alcohol spirits.

Wash your hands first, then soak them in alcohol for a while, and then handle the gut in a clean place. When the gut is ready, soak the gut in alcohol for a while. The disinfection should be more complete.

Li Mengxi thought.

So, he went looking for alcohol.

I washed my hands well with strong liquor.

Then, I rubbed a few gut strings again.

The catgut made by Li Mengxi is roughly as thick as a sewing needle.

Although Li Mengxi felt that it was still a bit thick, it would probably be usable if the wound was sutured.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! As for the strength of the catgut, it is amazingly strong, tough and strong, and it will keep pulling even if you pull it hard.

Li Mengxi held the catgut tightly in his hand, fearing that dust on the road would contaminate the catgut.

When he arrived at the wounded soldier's camp, Li Mengxi saw two local warriors carrying out a wounded soldier who had lost his voice.

The wounded soldier on the stretcher was pale, his eyes were closed, he was silent, and his face was discolored.

Apparently, he is dead.

When he found the military doctor Bu, Li Mengxi was surprised to find that Bu was suturing the wound.

To be precise, Bu was holding a thin silver needle used for acupuncture and using his hair as suture, and was concentrating on suturing the abdominal wound of a wounded soldier.

Li Mengxi was surprised.
