Chapter 2513 Non-Bleeding Surgery

"That's meaningless." Su Yun said, "Humans have 46 chromosomes, and gorillas have 48, but they can't be born with 47 chromosomes... Eh? Why are we talking about this?"

"It's not you." Zheng Ren fiddled with the hair on the soles of the patient's feet twice with sterile gloves, pondering how to solve this problem.

"It has nothing to do with reproductive isolation, and it has nothing to do with genetic changes. I think the situation is like hair migration." Zheng Ren twisted the hair that grew on the soles of his feet with his hands, and gently placed it on his fingers. The outer layer, as you walk deeper, gradually stimulates the nerve endings in the thicker layer of skin on the foot."

"Boss Zheng, please speak slowly." Zhou Litao didn't hear clearly, so he asked immediately if he didn't understand.

"I can't understand what I'm saying." Su Yun seemed to have forgotten the smell of the patient's sweaty feet, and moved closer to Zheng Ren's finger, carefully looking at the extremely thin hair, and said, "That's true, I remember That article was published by a doctor in Brazil."

"Brother Yun, what is it?" Zhou Litao asked.

"The "Journal of Emergency Medicine Vision" has a similar case report. I think the hair quality of white people is soft, and the possibility of hair migration is unlikely." Su Yundao, "Normally speaking, people with more hair quality and harder hair It is more likely to occur in Asian populations."

"But this hair...is a bit soft."

Su Yun moved closer and looked at the hair twisted by Zheng Ren's fingers seriously.

Zheng Ren was very worried that Su Yun would faint like Lin Yuan. After watching for a while, his eyes were already filled with tears.

It's not the depth of love, it's just that the sour smell is too strong.

"Boss Zheng, that's it?" Zhou Litao looked at a hair on the sole of his foot in doubt. It was really hard to connect the patient's severe pain with it.

Zheng Ren then lightly touched the root of the hair with his other hand.

"Oh..." The patient yelled out in pain.

"Does it hurt so much?" Su Yun asked.

"It hurts...it doesn't hurt that much, but I'm used to it." The patient said with some fear: "As long as you apply a little force, it will hurt when you touch it. I...I'm not pretending."

"I know, the hair penetrates the cuticle, extends deep into the soles of the feet, and touches the nerve endings." Zheng Ren said softly, "Looking at his pain, the location of the hair entry should be a little deeper."

"Use tweezers, I'll do it." Su Yun said.

"Don't." Zheng Ren said, "Take it under the microscope."

"Is it a big deal?" Su Yun asked puzzled.

"I have also read the article in the "Journal of Emergency Medicine Vision", because the patient is white, and the hair is relatively soft, just use tweezers to pinch it out. I think he should be careful, once some of the hair is left in the deep layer, if you want to remove it It’s very troublesome to get out. Even if you cut it open, you won’t be able to find it.”

Zheng Ren expressed his true thoughts seriously.

The patient was sitting on the examination bed, stunned for a while, and he was still thinking about the reproductive isolation between humans and gorillas just now, and he didn't slow down.

It's all about what, my heel hurts, why is it so far away.

"Okay, put on your shoes and follow me to the disposal room," Zheng Ren said.

"Doctor, what are we going to do?" The patient froze for a moment and asked in a low voice.

"The hair fell off and was trampled on the soles of the feet by you, and then penetrated the cuticle and entered the position of the peripheral nerve." Zheng Ren said, "You need to 'pull' out that hair before your disease can be cured."

The patient still didn't understand. He felt that the little doctor in front of him was a bit young, but he had a strong aura, the kind that he couldn't question.

Putting on his shoes and padding his toes, he limped along to the disposal room.

"Lin Yuan, go to the operating room and get my microscope." Zheng Ren said, "Anymore... Forget it, if you contact Yiren, I still... I'll do it myself."

Zheng Ren probably felt that a little explanation was too troublesome, so he said a few more words to the patient, then turned and left.

Lin Yuan watched Zheng Ren leave in surprise, went to find the surgical equipment by himself, and asked in a low voice, "Brother Yun, what is Boss Zheng going to do?"

"Make a fuss over a molehill." Su Yun said, "Just use tweezers to pull it out. He insisted on cutting the cuticle under the microscope. How thick do you think the hair is?"

"60-90 microns." Lin Yuan said without thinking.

"That's right, it's less than 1/10 millimeter. Your Boss Zheng is mighty, and he's going to perform a non-bleeding surgical operation." No matter what Su Yun said, he didn't speak well.

"Brother Yun, don't you bleed?"

"Cut the cuticle, and the cuticle on the bottom of the foot is a little thicker, estimated to be about 100 microns. Then go to the germinal layer, where the adhesion between the body tissue and the hair is not very serious, and then the hair is pulled out."

"..."

Lin Yuan glanced at the patient, it was just a patient who came to the emergency department, no wonder Brother Yun would say that Boss Zheng was making a fuss out of a molehill.

The patient sat silently on the bed in the treatment room and waited. Soon he saw the young doctor coming back with a metal surgical box.

When he put on the operating microscope, opened the operating box, and took out small microsurgical instruments, the patient looked straight at Zheng Ren, who was full of technological sense, and had countless questions in his heart.

Before he could ask a question, he heard Zheng Ren say: "Here is the black line in the skin, and it needs to be differentiated from the migration of parasites."

"If it is a parasite on the epidermis, there will be no fixed pain, and the itching will be severe. With experience this time, you will know what to do next time you encounter a similar situation."

As he said that, the patient saw Zheng Ren install a small blade on the handle of the knife, as small as a children's toy. But the few strands of cold light reflected from the blade made him feel a little afraid.

Although he was a little scared, he gave himself psychological comfort in his heart.

It's okay, it's okay, I'll be anesthetized no matter what. I just don't know how fine a needle should be used for anesthesia with such a small scalpel blade.

wrong! Why didn't I see the needle for anesthesia? besides! I didn't see anesthesia either!

The patient was stunned for a moment. Before he understood what happened, Zheng Ren had already slapped the knife aside, and then took a pair of tweezers.

"Doctor, don't you need anesthesia?" The patient asked anxiously.

"It's done, no need for anesthesia." Zheng Ren said lightly, and then looked at the hair that had just been removed in front of the light.

"This is……"

"It was you who walked barefoot at home and stepped on the hair. This hair got into the soles of your feet and stuck in like a needle." Zheng Ren smiled, twisted the hair onto a piece of sterile gauze, and then put the sterile gauze on it. Sterilized gauze is given to the patient.
