Chapter 1977: : Only minor surgery!

After Chen Cang came in, he gave Deng Ming a warning look:
　　 "Stay away from my son in the future!"
　　 Chen Cang is very vengeful and threatening.
　　 makes Deng Ming dumbfounded!
　　 "The operating room is arranged, the boss, you can start the operation at any time, would you like to see the patient's family?"
　　 Chen Cang took the film in his hand and watched it.
　　 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, for the New Year, whoever encounters this will be upset."
Wang Qing and Chen Bingsheng on the side of 　　 naturally heard clearly and clearly!
　　 Old Chen asked in a low voice, "Doctor Wang? Is this... a minor operation?"
　　 Wang Qing was speechless for a while, and didn't know how to answer such a question!
　　 If this is a minor operation, is it so entangled?
　　 You didn’t see my eyebrows furrowed, how heavy is my psychological burden?
　　 Silence is the best answer.

　　 Operating room.
　　 Chen Cang changed his clothes.
　　 Obviously, this is not the first time I came 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.
　　 Lao Chen on the side stared straight at Chen Cang.
　　 This made Chen Cang feel guilty.
　　 If they ask, how should they answer?
　　 After all, the surgery I did there?
　　 Lying is really a technical job.
　　 Chen Cang unfortunately didn't learn this skill.
　　 To be honest, eye surgery focuses on precision, but it is also difficult.
　　 all depends on operation!
　　 There are not so many bells and whistles.
　　 In many cases, it just relies on the polishing of basic skills: stitching!
　　 Liu Jian is on duty as an anesthesiologist.
　　 Eye anesthesia does not require general anesthesia, local anesthesia is fine.
　　 But in order to prevent the child from waking up suddenly and affecting the operation, Liu Jian chose a stable foundation + local anesthesia.
　　 Eye surgery needs to be performed under a microscope.
　　 It is also a special microscope, with a series of devices such as a light source and a condenser.
　　 This kind of operation is much more difficult than other operations.
　　Because subtle manipulations may affect the sclera, cornea and even the eyeball!
　　 Chen Cang holds a pen in both hands, 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, besides, they can shout a few times: "Come on."
　　 But obviously the atmosphere does not match the operating room.
　　 After Chen Cang is ready here, he uses a knife to gently incise the bulbar conjunctiva at the wound 2mm behind the limbus.
　　 The full name is no blood oozing out!
　　 Even the small blood vessels outside are bypassed as much as possible.
　　 This step is easy and difficult!
　　 Wang Qing's eyes widened, watching this scene, completely unable to believe it!
how did you do that?
　　 This has to avoid the nerves and blood vessels around the eyes perfectly.
　　 There is no vascular and nerve distribution in the cornea. This is why cornea donation is often looser. At least many diseases will not be transmitted to the cornea.
　　The scleral structure is dense and tough!
　　Although he has no blood vessels, the scleral catheter that penetrates the entire sclera has arteries, veins and nerves through it, and there is also an eyeball fascia on the envelope.
　　 Not only is it difficult to choose the position, but the weight of the scalpel needs to be grasped, and even the position must be grasped!
　　 But Chen Cang's knife is very easy and casual!
　　 With a light stroke, the incision is completed.
　　 Very perfect cut!
　　 This step is already an extremely difficult step in the eyes of all ophthalmologists.
　　 But for Chen Cang, it may really be a minor operation!
　　 Next, Chen Cang replaced the knife with tweezers in his right hand.
　　 began to separate the bulbar fascia sac, fully exposing 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 area.
　　 It is not difficult to take it out.
　　 But after taking it out, the suture to the sclera and the fixation of the lens are completed, all this is too difficult!
　　Moreover, the texture of the sclera is hard, making the operation difficult.
　　 But this time? 　Chen Cang is holding a long needle? 　The stitching method from the inside to the outside!
　　 "This is... the triangulation method?"
　　Chen Cang nodded, looking at Wang Qing a little curiously and asked: "Yes, you've seen it?"
　　 Wang Qing is a little excited!
　　 Where did he have the chance to see such a tall lens fixation technique! ?
　　 He said with some excitement: "Have you seen it? 　 But... It is written in the latest guide in 2023 that Professor Aubali proposed such a triangular fixation technique in the conjecture of the best fixation method for intraocular lens implantation!"
　　 "But everyone generally thinks that this stitching technique is difficult to achieve? 　 So... everyone thinks it's just a guess!"
　　 Chen Cang said, he did not expect that there are so many stories about this stitching technique!
　　 But, although he was talking? 　 But the needle and thread in his hand did not stop.
　　After making a small triangular scleral flap? 　Through the ciliary sulcus with a long needle from the outside to the inside? 　The needle insertion point is behind the corneoscleral limbus.
　　 From the opposite side, use a sharp needle to pass through the ciliary sulcus from the outside to the inside? 　 Then insert the long needle into the needle, and the long needle is guided through the opposite ciliary sulcus!
　　 The technique, stitching and threading in the whole process are very relaxing!
　　 But what Wang Qing saw was very excited.
　　Really!
This is real!
　　If you follow Professor Chen's method? 　It can be achieved.
　　 At this moment, he admired Chen Cang from the bottom of his heart.
　　 is an emergency doctor, but he can do eye surgery!
　　 Next, sclera repair!
　　 When suturing a scleral tear, be sure to recognize the wound edges on both sides of the wound!
　　Because the sclera's parenchymal layer is composed of dense collagen, it is 1mm thick and easy to recognize.
　　 But it is very difficult to align the scleral parenchyma closely.
　　 But this time, Chen Cang took over the needle and thread.
　　 suddenly frowned.
　　 "Give me 10-0 sutures!"
　　 Wang Qing heard the sound, and suddenly asked worriedly: "Will it be too crispy?"
　　Chen Cang shook his head: "The 8-0 suture is strong enough~EbookFREE.me~ but it is too thick. The sclera must be sutured tightly, and the wound should be smooth and leak-proof."
　　 "The 8-0 suture is not perfect!"
　　 "Let's do it, you are optimistic, I will teach you how to use 10-0 sutures to be firmer!"
　　 After speaking, Chen Cang started his own operation!
　　 Wang Qing's eyes lit up.
　　 Is this to teach a secret?
　　" The 10-0 suture is too thin and not strong enough, so if you want to make up for the defect, you should pass through at least 2/3 of the thickness of the sclera when you don't need to suture, 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 come out, large wounds should be exposed and sutured from the front to the back..."
　　 Chen Cang said very carefully.
　　 But Wang Qing was shocked!
　　 This fucking... is it really a minor operation?
　　 A minor operation, Professor Chen has already broken the two difficulties of the current world progress!
　　 The operation was completed quickly.
　　 did not spend much time at all.
　　 At this time, the operating room door opened.
　　Nurse Qin Yali said, "Director Chen, the experts from the Eye Hospital are here!"
