Chrysanthemums, there are many poems describing chrysanthemums, but in modern times, the more famous one is this one: When autumn comes on September 8th, after my flowers bloom, hundreds of flowers will die. The incense formation soaring to the sky penetrates Chang'an, and the whole city is covered with golden armor.
Moreover, I don’t know which master used the chrysanthemum as a metaphor for the anus. This master is awesome, and his descriptions and metaphors of the anus are spot on. She is not from the medical field, but she probably specializes in anal and anus-related work.
Otherwise, ordinary people would never be able to describe such an apt metaphor. Why is the chrysanthemum described as an anus, not a lily, not a morning glory?
There is a reason for this. There are two types of flowers on the chrysanthemum inflorescence. One of them is the simple chrysanthemum, commonly known as the "flower heart". The corolla is connected into a simple shape. It is a bisexual flower with a pistil in the center, a stigma with 2 lobes and a seed. There is a room below the house, surrounded by five stamens of flowers.
It's this kind of flower that looks exactly like the anus. Especially it looks very similar to the tight anus.
The anus has a complex structure. It is about 4cm long. When it extends from the rectum to the anus, it begins to become thicker, like lips. There is also an upright anal column.
The mouth has teeth, and the anus has anal pillars, just like the teeth open from the throat. The anal pillars are like muscle cords, like a toothless old man or old lady. It is no exaggeration. Some strange diseases will cause anal teeth to grow, and these teeth come out from the anal column.
I guess Nuwa was lazy when she created the human being, so she used the mouth as a template to make the anus.
People are so strange. Things that were originally unrelated to each other, but if you analyze them carefully, you will find that they actually come from the same source.
For example, kidneys and testicles (a) are cousins, and kidneys are almost an enlarged version of **. The two of them played together until the moment they were born.
There is a rich sublingual venous plexus under the tongue, and a super developed internal and external rectal venous plexus in the anus. This terminal venous plexus is so developed that it is almost like a spider web lying around the anus.
There are currently many theories on the cause of hemorrhoids, such as the drop theory and the varicose vein theory, but they are all inseparable from this venous plexus.
Sitting and standing for a long time, squatting for half an hour while looking at mobile phones in the bathroom, and foreign objects in the anus are all the main culprits of hemorrhoids.
Many people have a liquor banquet on the first day and not only have a headache but also anal pain the next day. This is because a large amount of irritating food can cause congestion at the ends of blood vessels.
Over time, the blood vessels become enlarged and thickened by the blood, and then become congested. Then, the congested blood vessels take the surrounding fat and turn into a bag.
Suddenly one day, the bag suddenly fell out of the anus and hung like a ball in the anus. This is the origin of hemorrhoid prolapse.
Prolapsed hemorrhoids not only look weird, but are also very painful, like a pinching pain after being incarcerated. It can make a strong man cry for his father and mother, rolling down his face in tears and screaming: Yao! youngest! youngest!
What a good man without tears? Let him try prolapse and incarceration.
There is a white line at the anus, which tightens the place where the intestine comes from like a rubber band. This is the famous dividing line between internal and external hemorrhoids.
Above the linea alba are internal hemorrhoids, and below the linea alba are external hemorrhoids. Of course, since there are internal and external hemorrhoids, there is a mixture.
Anal fistula is a disease that seeks another channel. 90% of anal fistulas are caused by perianal abscesses. This thing just opens a hole directly in the buttocks and leads directly to the intestines, forming an anus without an anal column!
Anal fistula is very troublesome to treat. For incisional treatment, the lumen is directly violently cut, causing the body to grow new granulations to block it, which is very painful.
The second type is thread setting treatment. Use a rubber band or corrosive medical thread to enter through the fistula opening on the buttocks, then pass through the rectum and finally exit through the anus, and then tighten it.
In fact, the tissue in the anal fistula channel is tightly tied with a rope, allowing it to undergo ischemia and necrosis, and then the body can regrow new tissue on its own.
The third method is to directly remove the entire fistula tract. The originally toothpick-thin channel is cut into a chopstick-thick channel, and then sutured.
The most terrifying thing is complex anal fistula, which cannot be treated. The only way to drain the drainage is to hang a thread. In professional terms: living with a fistula is also a safe choice. It stinks all the way!
Because of some special anal fistulas, if the estimation is insufficient and the levator ani muscle is damaged during treatment, it will be a serious problem. Maybe if you suck in the cool breeze, your anus will spurt out fecal residue.
"Raise the bed!" After Zhang Fan finished packing, he stood in front of the operating bed and gestured, then said to the circulating nurse. The advanced operating table is like a tower crane. Below it is the cross-triangular hydraulic steel bar. Through electric remote control, it is slowly unfolded and the bed is raised.
The old-fashioned operating table is like an old-fashioned cannon. When raising the bed, the circulating nurse has to grasp the disc with a handle to rotate it. Because there is no booster, people with little strength in their arms cannot move it at all.
After adjusting the operating bed, Zhang Fan began the operation. This operation was very simple.
Use a guidewire that has a certain hardness but can turn, like a thin guidewire like a hard plastic rod, with a silk thread tied to one end, and enter slowly.
Anal fistula is not necessarily a straight line. It is like a bully who is afraid of the strong. When it encounters a place with rich vascular plexus and many systemic immune factors, it will go around.
Zhang Fan slowly inserted the plastic rod into the anal fistula. You must not rush this, otherwise you will either go the wrong way or insert it into the normal fat layer.
This kind of surgery is usually performed by married doctors, and unmarried doctors cannot do it, especially single women who don’t understand what it means to do it slowly. And because Zhang Fan has a system, he can.
The guidewire with the silk thread entered the anal fistula little by little. Zhang Fan approached the patient's anus, which meant it was disinfected, otherwise the patient would be suffocated to death.
Zhang Fan closed his eyes and felt the direction of the guide wire through his hands. Inserting it bit by bit, when he suddenly felt a breakthrough, Zhang Fan knew that the guide wire had entered the rectum at this time.
Even the textbooks say it is a sense of breakthrough, but what is a sense of breakthrough? It feels like a breakthrough when it is inserted into the normal fat layer, and it feels like a breakthrough when it protrudes from the fistula.
How do novice doctors understand this? Really, this feeling can only be experienced after getting married and experiencing it carefully. For example, when you play with a balloon, the moment you pop the balloon with your finger, you feel a sense of breakthrough.
Those who don’t understand will never understand; those who understand will understand as soon as the teacher talks.
For example, Zhang Fan closed his eyes now and felt the breakthrough sensation from the guide wire. He understood that it had entered the rectum and definitely not fat.
After entering the rectum, you need to be even more careful. The intestinal wall of the rectum is very thin. It is easier to insert into the fat layer here. If you use improper force and puncture the rectum, it will be funny.
Feeling and experience are so important in this kind of surgery without visual conditions. It is absolutely true that one more surgery can lead to one more surgery.
Experience can be gained through work.
The cultivation of hand feel is very troublesome. You need to touch and practice more, but you can't practice too much.
For example, the sensory system on the belly of the hand is the most sensitive, but once it is used too much, the skin on the belly of the hand becomes keratinized and the sensitivity decreases.
Therefore, Zhang Fan never comes to do housework at home, just to keep the skin on his hands sensitive.
After entering the rectum, Zhang Fan then used gentle force to turn the guidewire from the opening to parallel to the rectum. This is a little difficult. What is kneading strength? For example, when you and your wife are arguing, you push her, and then pull her into your arms with a little strength. This is soft strength.
"Tooth tweezers!" Zhang Fan said to Zhuang Hongxu when he felt that he was approaching the anus.
Zhuang Hongxu neatly handed the toothed tweezers to Zhang Fan. Loosen and close it, open the small opening of the tooth forceps slightly, and then insert it along the anus. When the tooth forceps has entered about three or four centimeters, open it.
It's just a simple anal dilator.
"It's out, it's out." The traveling nurse's sharp eyes saw the black guide wire for the first time. Zhang Fan pulled the thread at the head of the guidewire to align with the tail of the guidewire in his hand.
Now comes the difficulty of the surgery. Although the road ahead is difficult, there are still traces to follow. But the last step really depends on experience.
Not only Zhuang Hongxu, but also the doctor in charge of the bed watched Zhang Fan's operation with wide eyes.
Zhang Fan held the guide wire in one hand and the rubber band in the other, and slowly began to operate...
The eyes of several assistants grew wider and wider. This step in the operation was the most critical step. The previous director could not explain it at all, but Zhang Fan spoke now! ~
