Medical road

The human body can be roughly divided into three cavities, the chest cavity, the abdominal cavity and the pelvis.

Especially the pelvic cavity, with natural evolutionary choices, is very different.

For example, Europeans and Americans, because in ancient times, their medical technology can not say that all diseases are bleeding, minor illnesses are released, serious illnesses are released, and even one of their presidents was bled to death.

This has also led modern European and American men to like women with very, very generous pelvic cavity, because only this kind of woman can survive.

Therefore, they think that the pelvic women who are as wide as the door panels are the most beautiful. In fact, there is a reason for this. Just like the old lady in the neighborhood who likes to gossip see someone's new wife, the first sight is not a face , But pigu egg.

Because the pelvic cavity is wide, the risk is relatively small during pregnancy and childbirth.

The hip joint is the outermost tissue of the pelvis.Many people, especially some young people, walk for a little longer, and there will be chuckles in the hip joints, as if someone snaps their fingers.

This is because although the length of the legs has not reached the error of the lame leg, it has reached the limit of the body to adjust.

If you don’t deal with the long-term uneven stress and wait for it to exceed the compensation of the body, then it will lead to arthritis over time. The easiest way is to put a slightly thicker shoe on the shorter side. A little insole.

The surgical plan used by Zhang Fan is the posterolateral approach.The doctors in the audio-visual room watched quietly. Although they didn't say anything, they still admired Zhang Fan's level.

At Zhang Fan's age, it was placed in their department, either as an intern at Regou or as a graduate student.

But as for Zhang Fan, he has already started to perform orthopedic surgery, which is considered top-level surgery, and he chose the most complicated surgery method, but the best way for the patient to recover.

This leaves everyone speechless, what can they say, what else can they say?But after sawing the bones, Zhang Fan wanted to put on the prosthesis directly.

In the audio-visual classroom, as if water enters hot oil, there is noisy noise. They are all orthopedic doctors or top three doctors in large hospitals. Everyone has no idea about the procedure of the operation.

The most difficult part of a hip replacement is the placement of the prosthesis. The placement is longer and shorter. Without even thinking about it, the patient is lame.

Also, if the measurement of the prosthesis is inaccurate, after the patient is discharged from the hospital, he may walk and choke, and a big bag may come out on the pigu, just like a big peach grows on the pigu.

Then there is the thigh of the affected side, like a big windmill, a big split!

The lighter ones need to go to the hospital, let the doctor pull the leg to restore the prosthesis into the acetabulum, the heavier ones may cause permanent disability of the patient.

Therefore, when Zhang Fan skipped the measurement, the doctors' eyes became round.

"Mischief! Director, he..."

Lin Cong listened to the noise in the electronic classroom while watching Zhang Fan's movements. He was actually puzzled in his heart, but thinking about Zhang Fan's skills, thinking about Zhang Fan's personality, he felt that Zhang Fan would not appear so important. Mistakes.

But, at this time, can he stand by?No, for nothing else, just for the patient, just because he is the director, he has to ask.

He did not stop or pay attention to the noise in his ears. He stood up and picked up the phone of Unicom's operating room.

"Dr. Zhang, is the measurement tool uncomfortable, or I'm asking them to change you a brand of measurement tool."

Lin Cong's tone seemed relaxed, but there was a solemnity on his face. If Zhang Fan really forgot the measurement, then needless to say, he would immediately stop Zhang Fan from continuing the operation.

"Oh, Director Lin! No need to change, it works well."

Zhang Fan said without lifting his head.

"Uh!" Lin Cong was choked by Zhang Fan, "Why don't you measure it?" No way, Lin Cong wanted to ask in a roundabout way, but Zhang Fan didn't go on the road.

People have their own habits and hobbies.The most unbearable thing about Zhang Fan on the operating table is being disturbed.

At the beginning, this was a habit that Zhang Fan had cultivated desperately. Being disturbed on the operating table was like breaking Zhang Fan's food stamp. Zhang Fan was very, very annoyed.

"Gibosn's operation was improved by Moore, and Moore's operation was improved by Dr. Shibi again. Haven't you thought about continuing to improve! Isn't it a waste of time to measure?"

The tone was flat and the foreign language was not standard, but the meaning was too strong. Lin Cong was so strong that Lin Cong couldn't speak, and the doctors who were so strong that the electronic classroom were all stuck.

Improvement, especially the improvement of surgery, is easier said than done.Most of the surgeries that are popular nowadays are done almost how they were done at the beginning, but they are still done almost exactly now.

That is, people who occasionally have one or two headband auras who dare to improve, most of the others just follow the rules. Even if most of them don't learn to follow the rules, the improvement is not easy.

"Improved? He wants to improve? How can he improve?"

One or two looked at the doctors next to them, with question marks in their eyes.

When Dr. Wang heard Zhang Fan's words so awesome, he almost threw the hooks in his hands. These words were too scary!~

"Doctor Zhang, how is this improved?" He couldn't suppress the question in his heart.

"With the acetabulum as the center point, create a precise three radiating moment lines in your mind, with the lateral line perpendicular to the long arm BX line.

The lower measuring line sets A1-B1 high eccentric moment perpendicular to the body.

The medial line is perpendicular to the pubic bone and runs the line A2-B.

Two points can fix a straight line, three points can fix a triangle, and the acetabulum, pelvis, and lower extremities are exactly a triangle!"

Zhang Fan said and did it.This method is based on how many days and nights he practiced in the system.

This method combines the patient's MRI and CT to locate the hip joint very accurately.

To put it simply, the starting point and ending point of the bones are determined, and the position is directly fixed.

If this method is used, the hip replacement surgery will become very simple, but this method requires the doctor's sense of space, torque calculation ability, and pressure load estimation of the lower limbs.

To be honest, it is impossible for ordinary doctors to construct an accurate structural diagram of a patient in the mind.

However, Zhang Fan relied on countless trainings, relied on the strict requirements of the system, and failed again and again, and finally developed his own set of surgical methods.

His method is more accurate than conventional surgical methods. As long as human factors are involved, there will be some errors. Zhang Fan directly determines the position at the source. It can be said that as long as the material does not change, he does it. The surgery has not changed, it is so precise.

Moreover, it saves time even more. At least half an hour of wound exposure can be reduced, compared to how many and a half hours are needed for the entire operation.

It is estimated that many people, when they were still green boys, or the big devil, may have opened a mechanical alarm clock with a screwdriver. At that time, they might not be impressed by the fineness of the alarm clock.

In fact, the degree of sophistication of the human body, in comparison, is definitely much higher than the complexity and degree of sophistication of the machinery made by humans.

Moreover, the most important thing is that the body's organs have the function of self-recovery and self-regulation.

Not to mention others, just talk about human feet, the size is actually a certain surprise.

The upper limbs and lower limbs are actually surprising in length.If the length of the lower limbs exceeds two centimeters, it will surpass the human body's compensatory capacity, and it will be limp, and it will be called limping when walking.

There are three difficulties in hip replacement surgery. The most frightening one is uncontrollable fat embolism.

As the saying goes, eating meat is worse than chewing bones, and chewing bones is worse than licking fingers. The fragrance is because of a fat.

There is a lot of fat in the medullary cavity of bones, and the essence of bone marrow is actually phospholipid, which is the so-called fat.

Once this is opened, a large amount of adipose tissue will liquefy and then enter the blood. To be honest, according to the current medical level, it is unavoidable.

Fat embolism is the biggest uncertainty in orthopedic surgery.How terrible this uncertainty is, it can be said that once fat embolism enters the more important organs, such as the lungs, to be honest, even if the patients are in the hospital, most of them are too late to be rescued.

In order to avoid it as much as possible, orthopedic surgeons try their best to speed up the operation and reduce the damage. However, orthopedic surgery is almost a destructive treatment, so it is very contradictory.

However, Zhang Fan's method saves time, which means that his method can more likely avoid fat embolism in patients.

Zhang Fan said while doing it.Whether it is Dr. Wang on the operating table or the doctors in the audio-visual room, the brain quickly wants to repeat Zhang Fan's way.

It's too difficult.Especially Dr. Wang, the big sweat beads on the tip of the nose under the mask slowly ooze out.

It's too difficult, my brain feels painful, and it's too difficult to replicate.

"Prepare the bone cement and set the shape in two minutes." Zhang Fan did not stop.Said a word to Dongshan girl on the edge of the operating table.

And Dongshan girl looked at Zhang Fan with admiration. Although she didn't understand what Zhang Fan said, she understood every word Zhang Fan said, but they were like a bunch of gibberish. .

However, Dongshan girl thinks that Zhang Fan is very tall.She has been on the operating table of countless experts, and none of them make her feel that surgery can be done so easily, and it can make people feel tall.

Especially when I met some doctors with bad techniques, a measurement, to be honest, was about to become a target for the sighting missile.

With one eye closed, he bent over and looked at one of the patient's legs. To be honest, sometimes she felt unreliable, but although Zhang Fan didn't take measurements, it just made her feel reliable.

Perhaps this is the sixth sense of a woman.

The prosthesis of the hip joint is like a pistol or the upper end of the leg bone that everyone usually gnaws on.

When installing this thing, first put the prepared bone cement in the expanded medullary cavity, and then insert and fix it, so that the prosthesis and the bone are permanently bonded together.

Bone cement is not what kind of cement is used to build houses on ordinary days. The bone cement used in the operating room solidifies very fast. It takes seven or eight minutes to form and solidify. If it is a little slower, the prosthesis will not fit properly.

Therefore, when the Dongshan girl was about to prepare bone cement, Dr. Wang was still stunned, with an obsessive expression on his face.

"Haha, how do you figure it out? It's simple."

Zhang Fan asked with a smile like a devil.

"No!" Doctor Wang returned to his soul, and then asked urgently.

When Zhang Fan talked and did it, he could see that Zhang Fan didn't talk nonsense, he really improved the operation!

And the doctors in the audio-visual room were not bad-sighted. As Zhang Fan's operation continued, they also saw that Zhang Fan improved his hip surgery method.

Finally, Dr. Wang asked everyone's questions, and everyone's very concerned questions, "How did you do it."

Doctor Wang looked at Zhang Fan eagerly, just as Little Wawa watched other little girls chattering with popsicles but he didn't, he looked at Zhang Fan eagerly.

Just a word: Can you give me a bit?
