Chapter 1972 It's Just a Minor Operation! (Seeking a Monthly Ticket)

After Chen Cang came in, he gave Deng Ming a warning look:

"Stay away from my son in the future!"

Chen Cang made a vengeful threat.

Make Deng Ming dumbfounded!

"The operating room has been arranged, Boss, the operation can start at any time, do you want to meet the patient's family?"

At this time, Chen Cang started to read the film with his hand in hand.

After reading it, he breathed a sigh of relief. It seemed that the operation was not very difficult. He nodded and said, "See you!"

"After all... Minor surgery, let the patient's family feel at ease. Anyone who encounters this will feel bad when it's Chinese New Year."

Naturally, Wang Qing and Chen Bingsheng who were on the side could hear clearly!

Old Chen asked in a low voice, "Doctor Wang? Is this...a minor operation?"

Wang Qing was speechless for a moment, not knowing how to answer such a question!

If this is a minor operation, why bother?

Didn't you see how heavy my psychological burden is?

Silence is the best answer.

...

...

In the operating room.

Chen Cang changed his clothes.

Obviously, it wasn't the first time to come for surgery in the middle of the night.

But to be honest, this is also the first time Chen Cang has performed eye surgery in reality.

Old Chen on the side stared straight at Chen Cang.

This made Chen Cang feel guilty.

If they ask, how should I answer?

After all, the operation I performed there?

Lying is really a technical job.

Unfortunately, Chen Cang did not learn this skill.

To be honest, ophthalmic surgery focuses on precision, but it is also difficult to be precise.

It all depends on the operation!

Not so many bells and whistles.

Most of the time, it depends on the polishing of basic skills: stitching!

Liu Jian is on duty as an anesthesiologist.

Ophthalmic anesthesia does not require general anesthesia, local anesthesia is sufficient.

But in order to prevent the child from waking up suddenly and affecting the operation, Liu Jian chose a safe foundation + local anesthesia.

Eye surgery needs to be performed under a microscope.

Moreover, it is a special microscope with a series of devices such as a light source condenser.

This type of operation is much more difficult than other operations.

Because subtle operations may affect the sclera, cornea and even eyeballs!

Chen Cang holds a pen in both hands, his hands are as steady as a rock!

Surgery is about to begin!

No one can help with this operation.

Wang Qing and Deng Ming could only do chores, and besides that, they could still shout a few times: "Come on."

But obviously the atmosphere doesn't match the operating room.

Here, after Chen Cang got ready, he gently incised the bulbar conjunctiva at the wound 2mm behind the limbus with a knife.

The full title is No Blood Oozed!

Even the small outer blood vessels are bypassed as much as possible.

This step is as easy as it is difficult!

Wang Qing's eyes widened, watching this scene, he couldn't believe it at all!

how did you do that?

This has to perfectly avoid the nerves and blood vessels around the eyes.

The cornea does not have blood vessels and nerves, which is why it is more relaxed to donate corneas in many cases. At least many diseases will not be transmitted to the cornea.

And the structure of the sclera is dense and tough!

Although he has no blood vessels, the scleral duct that runs through the entire layer of the sclera has arteries, veins and nerves passing through it, and there is also ocular fascia on the surface.

Not only is it difficult to choose the position, but the weight of the scalpel needs to be grasped in place, and even the position must be grasped!

But Chen Cang's knife is very easy and casual!

With one swipe, the incision is completed.

A perfect cut!

This step alone is already an extremely difficult step in the eyes of all ophthalmologists.

But for Chen Cang, it might really be a minor operation!

Next, Chen Cang replaced the knife with tweezers in his right hand.

Begin to separate the bulbar fascia sac and fully expose the scleral wound!

After entering the sclera, the lens can be clearly seen through the aqueous humor!

The lens is now partially embedded in the vitreous region.

It is not difficult to take it out.

But after taking it out, it is too difficult to suture the sclera and fix the lens!

Moreover, the texture of the sclera is hard and the operation is difficult.

But at this time, Chen Cang held a long needle and sutured it from the inside out!

"Is this... the triangle fixation method?"

Chen Cang nodded, looked at Wang Qing curiously and asked, "That's right, have you seen it?"

Wang Qing was a little excited!

Where did he have the opportunity to see such a tall lens fixation technique! ?

He said with some excitement: "I haven't seen it, but...the latest guideline for 2023 states that Professor Aubari proposed such a triangular fixation method in his conjecture on the best fixation method for intraocular lens implantation!"

"But everyone generally thinks that this kind of stitching technique is difficult to achieve, so... everyone thinks it's just a guess!"

Chen Cang snorted, he didn't expect that there are so many stories about this suture technique!

However, although he spoke, the needle and thread in his hand did not stop.

After making a small triangular scleral flap, use a long needle to pass through the ciliary sulcus from one side from the outside to the inside, and the needle insertion point is behind the corneoscleral limbus.

From the opposite side, a sharp needle is used to pass through the ciliary sulcus from the outside to the inside, and then a long needle is inserted into the needle, and the long needle is guided through the ciliary sulcus on the opposite side!

The whole process of technique, stitching and threading is very easy and comfortable!

But Wang Qing was very excited.

real!

This is real!

If you follow Professor Chen's approach, it can be achieved.

At this moment, he admired Chen Cang from the bottom of his heart.

He is obviously an emergency doctor, but he knows how to do eye surgery!

Next, is scleral repair!

When suturing a scleral tear, be sure to recognize the wound margins on both sides of the wound!

Because the parenchyma of the sclera is composed of dense collagen with a thickness of 1mm, it is easy to identify.

But it is very difficult to make the sclera parenchyma fit tightly.

But at this time, Chen Cang took over the needlework.

Suddenly frowned.

"Give me 10-0 sutures!"

Hearing the sound, Wang Qing suddenly asked worriedly, "Is it too brittle?"

Chen Cang shook his head: "The 8-0 suture is strong enough, but it is too thick. The sclera must be sutured tightly, and the wound must be smooth and watertight."

"8-0 sutures are not perfect!"

"How about this, you look good, I will teach you how to use 10-0 sutures to be stronger!"

After finishing speaking, Chen Cang started his own operation!

Wang Qing's eyes lit up.

Is this going to teach secrets?

"The 10-0 suture is too thin and not strong enough, so if you want to make up for the defect, you should pass at least 2/3 of the thickness of the sclera when you don't need sutures, but not more than 90%!

Only in this way can the sclera fit well and have high strength!

In order not to cause more ocular contents to protrude, larger wounds should be exposed and sutured from the front to the back..."

Chen Cang said it very carefully.

But Wang Qing was shocked when he heard it!

This fucking...is it really a minor operation?

With a small operation, Professor Chen has already broken two difficulties in the current world progress!

The surgery was done quickly.

It didn't take much time at all.

At this time, the door of the operating room opened.

Nurse Qin Yali said: "Director Chen, the experts from the Eye Hospital are here!"

...

ps: Ask for a monthly pass!
