Chapter 1971

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

"Stay away from my son later!"

Chen Cang made a vengeful threat.

Let Deng Ming cry and laugh!

"The operating room is arranged, boss. You can start the operation at any time. Do you want to see the patient's family?"

Chen Cang watched the film in his hand.

After reading it, he was relieved. It seemed that the difficulty of the operation was not very high. He nodded and said, "see you!"

"After all... Minor surgery can make the patient's family feel at ease. It's bad for anyone who meets this thing during the new year."

Wang Qing and Chen Bingsheng on one side naturally heard clearly!

Old Chen whispered, "Dr. Wang? Is this... A minor operation?"

Wang Qing was speechless for a moment. He didn't know how to answer such a question!

If it's a minor operation, is it so tangled?

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

Silence is the best answer.

……

……

Operating room.

Chen Cang changed his clothes.

Obviously, it's not the first time to have surgery in the middle of the night.

But to tell the truth, this is also Chen Cang's first eye surgery in reality.

One side of Lao Chen stared at Chen Cang with straight eyes.

This made Chen Cang feel guilty.

If they ask, how should they answer?

After all, where did you do the operation?

Lying is really a technical job.

Chen Cang unfortunately did not learn this skill.

To tell the truth, ophthalmic surgery focuses on precision, and it is difficult to focus on precision.

It all depends on operation!

There are not so many fancy skills.

Many times, it depends on the grinding of basic skills: suture!

Liu Jian is on duty to be an anesthesiologist.

Ophthalmic anesthesia does not need general anesthesia, but local anesthesia.

However, in order to prevent the child from waking up suddenly and affecting the operation, Liu Jian chose stable basic + local anesthesia.

Ophthalmic surgery needs to be performed under a microscope.

It is also a special microscope with light source, concentrator and other devices.

This operation is much more difficult than other operations.

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

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

The operation is about to begin!

No one can help with this operation.

Wang Qing and Deng Ming can only do chores. In addition, they can shout: "come on."

But obviously the atmosphere doesn't go with the operating room.

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

No blood exudation!

Even the small blood vessels outside should be bypassed as much as possible.

This step is very simple and difficult!

Wang Qing stared at the scene and couldn't believe it!

How did this happen?

It's perfect to avoid the nerves and blood vessels around the eyes.

There are no blood vessels and nerves in the cornea, which is why the donation of cornea is relatively loose. At least many diseases will not infect the cornea.

The sclera is dense and tough!

Although he has no blood vessels, the scleral catheter through the whole layer of the sclera passes through arteries, veins and nerves, and the surface is covered with ocular fascia.

It is not only difficult to choose the orientation, but also the weight of the scalpel needs to be grasped in place, even the position!

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

A slight stroke completes the incision.

Perfect cut!

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

But for Chen canglai, it may really be a small operation!

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

Start to separate the bulbar fascia capsule 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's not difficult to take it out.

However, it is too difficult to complete the suture with sclera and the fixation of lens after removal!

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

But at this time, Chen Cang held a long needle and fixed the suture from inside to outside!

"This is... Triangular fixation?"

Chen Cang nodded, looked at Wang Qing with some curiosity and asked, "yes, have you seen it?"

Wang Qing is a little excited!

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

He said excitedly: "I haven't seen it, but... In the latest guide in 2023, Professor obari proposed such a triangular fixation method in the conjecture of the best fixation method for intraocular lens implantation!"

"But it is generally believed that this suture technique is difficult to achieve, so... Everyone thinks it is just a guess!"

Chen Cang Oh, he didn't expect that there were so many stories about this sewing technique!

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

After the small triangular scleral flap is made, the long needle passes through the ciliary sulcus from outside to inside from one side, and the needle entry point is behind the edge of corneoscleral sclera.

From the opposite side, the sharp needle passes through the ciliary sulcus from outside to inside, and then the long needle is inserted into the needle, and the long needle is guided through the contralateral ciliary sulcus!

The whole process of manipulation, needlework and thread are very relaxed and comfortable!

But Wang Qing was very excited.

really

It's true!

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

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

Obviously, he is an emergency doctor, but he can do eye surgery!

Next, scleral repair!

When suturing scleral lacerations, be sure to recognize the wound edges on both sides of the wound!

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

However, it is very difficult to make the scleral parenchyma close.

But at this time, Chen Cang took over the needle and thread.

Suddenly frowned.

"Give me 10-0 suture!"

Wang Qingwen suddenly asked with worry, "will it be too crisp?"

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

"8-0 suture is not perfect!"

"Well, watch it. I'll teach you how to use 10-0 suture to be firm!"

With that, Chen Cang began his own operation!

Wang Qing's eyes brightened.

Is this a secret to teach?

"The 10-0 suture is too thin and the strength is not enough, so if you want to make up for the defect, you should pass through at least 23% of the sclera thickness without suture, but not more than 90%!

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

In order not to cause more intraocular contents to fall out, in larger wounds, they should be exposed from front to back and sutured at the same time... "

Chen Cang said it very carefully.

But Wang Qing was shocked!

What the fuck... Is it really a minor operation?

A small operation, Professor Chen has broken two difficulties in the current world progress!

The operation was completed quickly.

It didn't take much time at all.

At this time, the operating room door opened.

Nurse Qin Yali said, "director Chen, an expert from the eye hospital is here!"
