v3 Chapter 2515： Non-bleeding surgery

"That doesn't make sense." Su Yun said, "A man has 46 chromosomes and a gorilla has 48. That is, there are 47 chromosomes left ... eh? What do we say about this?"

"It's not you." Zheng Ren fiddled with the hair on the soles of the patient's feet twice with sterile gloves, wondering 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 grows on the soles of his feet with his hands, and gently placed it on his fingers. "It is embedded in the skin. The outer layer, as you walk further, gradually stimulates the nerve endings of the thicker layer of skin on the feet. "

"Boss Zheng, speak slowly." Zhou Litao didn't understand clearly and asked if he didn't understand.

"I can't understand how to listen." Su Yun seemed to have forgotten the smell of the patient's sweaty feet, gathered it up with Zheng Ren's fingers, and carefully looked at the very fine hair, saying: "It really is, I remember That article was published by a Brazilian doctor. "

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

"A similar case report was published in the" Journal of Emergency Medical Vision ". I think the hair quality of white people is soft, and the possibility of hair migration is not high." Su Yundao, "Normally, the hair quality is too high and hard. It ’s more common in Asians. "

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

Su Yun stepped closer again, carefully looking at the hair twisted on Zheng Ren's fingers.

Zheng Ren was very worried that Su Yun would be fainted like Lin Yuan. He looked for a while and his eyes were already full of tears.

Not the deepness of love, but the sour smell is too heavy.

"Boss Zheng, that's it?" Zhou Litao looked at a hair on the bottom of his feet in doubt, it was really difficult to associate the patient's severe pain with it.

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

"Hmm ..." The patient shouted in pain.

"Does it hurt?" Su Yun asked.

"It hurts ... it doesn't hurt that much, but I'm used to it." The patient said a little scared. "As long as it's a little bit, it hurts when I touch it, I ... I'm not pretending."

"Know that the hair penetrates the stratum corneum, extends deep into the soles of the feet, and touches the peripheral nerves." Zheng Ren said gently, "Looking at his painful state, consider where the hair is going a little deeper."

"With tweezers, I'll come." Su Yundao.

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

"Did you make a big deal?" Su Yun asked, puzzled.

"I have also read the article in the" Journal of Emergency Medical Vision ", because it is a white patient, and the hair is relatively soft. It should be clipped out with tweezers. I think he should be careful about this. Once part of the hair is left in the deep, I want to take It's troublesome to come out. Even if you cut it, you can't find it. "

Zheng Ren seriously said what he really thought.

The patient was sitting on the consultation bed, listening to each other, and still thinking about what was just said about the reproductive isolation between humans and gorillas.

It's all about nothing, my own heel hurts, how to pull so far.

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

"Doctor, what are we going to do?" The patient froze and asked quietly.

"The hair fell off, and you stepped on the soles of your feet, then penetrated the stratum corneum, and entered the location of the peripheral nerves." Zheng Rendao said, "You need to 'pull out' that hair to get better."

The patient still didn't understand. He felt that the young doctor was a little young, but there was a strong aura in his body that could not be questioned.

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

"Lin Yuan, go to the operating room and get my microscope." Zheng Ren said: "Again ... forget it, you should contact Yiren. I still have to ... I'll do it myself."

Zheng Ren may feel that it is too much trouble to explain a little bit. He said a few words to the patient and turned to leave.

Lin Yuan looked at Zheng Ren in surprise, went to find the surgical equipment by himself, and whispered, "Brother Yun, what is Zheng Zheng doing?"

"It's a big deal." Su Yundao, "Pull it out with tweezers. He has to cut through the cuticle under a microscope. How thick is your hair, you think?"

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

"That is, less than 1/10 millimeter. Your boss Zheng is mighty, and he is going to perform a surgical operation that does not bleed." No matter what Su Yun said, he couldn't speak well.

"Brother Yun, don't bleed?"

"Cut the cuticle, the cuticle on the soles of the feet is slightly thicker, it is estimated to be about 100 microns. Then go to the hair growth layer, where the adhesion between the body tissue and the hair is not very serious, and then pull the hair out."

"..."

Lin Yuan glanced at the patient. He was just a patient who came to the emergency department. No wonder Yun Geer said that Boss Zheng made a big deal.

The patient sat silently on the bed in the treatment room and waited, and soon he saw the young doctor who had just come back with a metal operation box full of texture. UU Reading at

When he put on the operating microscope, opened the operating box, and took out the small microsurgical instruments, the patient's eyes stared at Zheng Ren, who was full of science and technology, and asked countless questions.

Before he asked, Zheng Ren said, "Here is the black line in the skin, which needs to be distinguished from the migration of parasites."

"If it is an epidermal parasite, there will be no fixed pain and itching will be very heavy. With experience this time, next time you encounter a similar situation, you will know what to do."

Talking, the patient saw Zheng Ren attaching a small blade to the handle, as small as a children's toy. But a few strands of cold rays from the reflected light on the blade made him feel a little afraid.

Although a little scared, he gave himself psychological comfort.

It's okay. It's okay. I just don't know how fine a needle is to make an incision with such a small surgical blade.

wrong! Why can't I see the needle for anesthesia? and also! I didn't see the anesthetic!

The patient froze, and before he could understand what was happening, Zheng Ren patted the knife aside and took a pair of tweezers.

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

"It's done, don't need anesthesia." Zheng Ren said lightly, and then looked at the freshly removed hair into the light.

"this is……"

"You walked barefoot at home and stepped on your hair. This hair is drilled to the bottom of your feet and pierced like a needle." Zheng Ren smiled, twisted the hair on a sterile gauze, and then put Give the gauze to the patient.
