Each skeletal muscle in the human body is divided into two parts: the muscle abdomen and the tendon, the muscle abdomen is composed of muscle fibers, the color is red and soft, and it has the ability to contract.

The tendon is made up of dense connective tissue, is white and hard, and has no ability to contract.

The tendon is the connective tissue fibrous cord at the end of the muscle, through which the muscle attaches to the bone or other structures, the tendon is tougher and smaller than the muscle, and its expansion strength is 611~1265 kg/cm².

Its surface is covered with a connective tissue membrane, and a small amount of connective tissue is connected between the collagen fibers.

Although the bundles of collagen fibers that make up the tendon are parallel to each other, each bundle of collagen fibers is intertwined, so the pull of the muscle fibers spreads to the entire tendon rather than to the individual tendon bundles.

Let's try it soon, everyone. 】

In clinical surgery, the flexor tendon injury of the hand often affects the function of the finger due to the formation of dense adhesions after suturing or tendon transplantation, resulting in surgical failure.

Therefore, it is important to preserve the nutrient supply of the transplanted tendon to prevent postoperative tendon adhesion.

But in fact, this step is indeed extremely difficult, and it is also the most difficult part of the postoperative hand function recovery.

Therefore, the step of tendon suturing often takes a lot of time.

But how long has it been?

Chen Kai looked at the time, it shouldn't have been more than 15 minutes...

At this time, Deng Wenbo sighed, "Doctor Li, your suturing speed seems to be fast again!" ”

He remembered that he was startled the last time he saw Li Xiyang stitched, and this time it seemed to give him a faster feeling.

Li Xiyang smiled, "Because I changed to a more convenient suture technique, but... It's not much faster, just three or four minutes! ”

The corners of Chen Kai's mouth twitched,

Just three or four minutes??

Are you talking the fuck human?

Tendon suture can be different from vascular anastomosis, whether it is a blood vessel or a nerve, the principle of anastomosis is to suture the two broken ends together, and the tendon is like a flat carpet, in order to make the suture not affect the postoperative activity of the tendon, the suture should deliberately leave enough area to ensure tendon blood circulation,

To put it simply, it is to perform multiple sets of sutures on a limited area.

And the more sets of sutures, the more it proves the surgeon's ability to precision sutures.

Not to mention others, take Chen Kai himself as an example, it will take at least two hours to complete six sets of stitches like the latter just now.

And that's on the premise of making sure that you can master that new suture technique.

And the guy in front of him only took 15 minutes, and he didn't take much time to take one bite at a time.

I've seen arrogance, but I've never seen such arrogance.

Chen Kai blew his beard and glared, furious.

But when I thought that the other party did have this arrogant qualification...

Chen Kai sighed lightly, full of powerlessness.

In front of this young man, he suddenly felt that his previous pride was crushed in an instant.

Who would have thought that this Renhe would be so crouching tiger, hidden dragon!

After the tendon is sutured, the next step is the vascular suture.

Chen Kai cleaned up his mood and stood in a position with a good view.

Now is not the time to be careful, and for any doctor who truly loves surgery, he will not want to miss such a good opportunity to observe.

Seeing the latter behaving like this, Deng Wenbo smiled secretly in his heart.

Looking back on that day, wasn't that true of him?

Li Xiyang, a young man, is really incredible.

The operation continues!

Microscope magnification 10x...

Remove the adventitia of the vessel 2~3mm around the anastomosis...

Prune to normal blood vessels...

Drawing the blood vessels makes the equilateral triangle...

Placement of vascular clips...

Note: It should not be placed for too long, away from the anastomosis, and clamp the adventitia of the blood vessel.

Flushing blood vessels...

Pull the blood vessels, and at the place where the needle is threaded, the blood vessel is low-pressure, which is convenient for the needle to penetrate...

Note: The needle must penetrate the entire thickness of the vessel wall, with the needle pitch being twice the margin and the margin being 3 times the vessel wall.

Generally 6 stitches, 4 stitches in the stalphth...

Resting position, 4 times the caliber!

Li Xiyang operated normally, while speaking.

It's like explaining it to everyone again.

At this time, everyone was immersed in his suturing technique.

I saw his hands fluttering up and down on the edge of the wound of the patient like butterflies.

In everyone's eyes, where is the stitching, it is clearly carving a work of art.

I thought that I had seen the most gorgeous suture just now, but at this moment I realized that it was not Li Xiyang's limit at all.

This kind of suturing is dazzling to watch.

But suddenly, the movements in Li Xiyang's hands stopped!

What?!

Sewn up again?

No, big brother, I haven't seen it yet.

Chen Kai seemed to have completely forgotten his position at this time, and he was sorry in his heart.

At this time, Lu Liang asked, "Doctor Li, did you use periaditum suture to suture the blood vessels just now?" ”

Li Xiyang nodded, not bad!

Lu Liang looked at Deng Wenbo and said suspiciously, "Director Deng, didn't you tell me before that saving lives on the operating table comes first, time is life, try not to use this kind of difficult hybrid surgery?" ”

Since the last time, Deng Wenbo found that Lu Liang's basic skills are very solid, so he has a lot of care in his days outside the bones.

The relationship between the two is also that of a teacher and a friend.

After Lu Liang asked, Deng Wenbo was not angry, "You also know that what I said is doing my best!" ”

"There is a difference between this main knife and the main knife, of course, the ordinary main knife is mainly steady, but if it is Dr. Li..."

As he spoke, Deng Wenbo pointed to the time on the wall.

Everyone saw that it only took eight minutes for the blood vessels to be sutured!

If it were someone else, it would be impossible to finish these eight minutes even if it was replaced with the most ordinary sutures.

Since it is a capable surgeon, it is natural to use the best suture method to help the patient recover the function of the hand to the greatest extent.

Only then did Lu Liang understand that it was not that the mixing technique was bad, but that there were very few main surgeries that could take into account the time and effect of suturing.

Think about it, this is Li Xiyang!

Chen Kai also nodded in agreement, even if he replaced him, he didn't dare to rashly use the hybrid technique.

This young man is simply a natural material to be the main knife.

This stitching is not only fast, but also stable, and the stitch is simply artistic.

After the vascular anastomosis is completed, whether it is successful or not depends on the blood circulation of the fingers.

Li Xiyang motioned to Lu Liang to release the vascular clip, and after a while, the artery distal to the anastomosis was visibly filled, indicating that the distal end of the replanted finger had a good blood supply.

Soon the skin of the finger transplant turned from pale to rosy, and the skin temperature increased.

It means that the blood circulation has been successfully rebuilt and the operation is quite perfect.

Seeing this scene, Chen Kai looked at Li Xiyang with a convincing look in his eyes, and he didn't dare to despise it anymore.

This is followed by nerve anastomosis as well as skin sutures.

10-0 microsuture, outer membrane suture...

Normal nerve, tension-free suture...

The index finger has survived, and the rest of the operation just needs to be careful not to hurt the blood vessels.

This is not too simple for Li Xiyang, and in less than 20 minutes, the battle will be completely resolved.

So far, the patient's index finger replantation has been successful.

In the same way, the middle finger is also unexpectedly replanted.

And then there's the last, and most difficult, level where you need to move your ring finger to your thumb!
