Chapter 635: Looking forward

Chapter 635: Looking Forward
The human body can be roughly divided into three cavities, the thoracic cavity, the abdominal cavity, and the pelvic cavity.
Especially the pelvic cavity, with the choice of natural evolution, is very different.
For example, Europeans and Americans, because in ancient times, their medical technology could not say that all diseases were bloodletting, minor diseases were small, major diseases were large, and even one of their presidents was bled to death.
This has also led modern European and American men to like the very, very wide pelvic women, because only such women can survive.
Therefore, they think that the pelvic women who are as wide as a door are the most beautiful. In fact, this is for a reason. Just like an old lady who talks about gossip in a neighborhood, her new wife is not at first sight , But pigu egg.
Because this pelvic cavity is wide, the risk is relatively small when pregnant.
The hip joint is the outermost tissue of this pelvic cavity. Many people, especially some young people, walk for a little longer, and there will be a rattling sound in the hip joint, as if someone clicked their fingers.
This is because although the length of the legs has not reached the lame leg error, it has reached the limit of the body to adjust.
If you do not deal with long-term uneven force and wait for the compensation beyond the body, then over time, it will lead to arthritis. The simplest way is to put a slightly thicker shoe on the slightly shorter side. A little insole.
The surgical approach used by Zhang Fan is a posterolateral approach. The doctors in the classroom looked at it quietly. Although they didn't say it, they admired Zhang Fan's level.
At the age of Zhang Fan, they are placed in their departments, either as hooked interns or students who are still studying.
But Zhang Fan, he has begun to perform orthopedic surgery as the top surgery, and the choice is still the most complicated surgical method, but the best way for patients to recover.
This leaves everyone speechless, what can they say, what else can they say? But when sawing the bones, Zhang Fan directly went to the prosthesis.
In the classroom, like water and hot oil, the noisy noises are rising up. They are all doctors of dry orthopedics, or the top three doctors in large hospitals. There is no clear idea of ​​the procedure in each heart.
The hardest part of hip replacement is the placement of the prosthesis. The placement is long and short. Don't even think about it. The patient comes down to the mule.
Also, if the measurement of the prosthesis is inaccurate, after the patient is discharged, maybe he walks around, a little bit, maybe a big bag will come out on pigu, just like a big peach on pigu.
Then there is the thigh on the affected side, like a big pinwheel!
The lighter need to go to the hospital, let the doctor pull the leg to return the prosthesis to the acetabulum, and the heavier may cause permanent disability for the patient.
Therefore, when Zhang Fan skipped the measurement directly, the doctors' eyes widened.
"Prank! Director, he ..."
Lin Cong's ear listened to the noise in the classroom, while watching Zhang Fan's movements, he was actually wondering, but thinking about Zhang Fan's technology and thinking about Zhang Fan's person, he felt that Zhang Fan would not be so important Mistakes.
But at this time, can he stand by and watch? No, not for the other, for the patient, for him as the director, he has to ask.
He didn't stop or ignore the noise in his ear, stood up and picked up the phone in the operating room.
"Dr. Zhang, isn't the measuring tool handy, or I'll ask them to change your brand of measuring tool."
Lin Cong's tone seemed very relaxed, but with a solemnity on his face, if Zhang Fan really forgot the measurement, then it goes without saying that he would immediately stop Zhang Fan from continuing the operation.
"Oh, Director Lin! No need to change, it works."
Zhang Fan said without raising his head.
"Eh!" Lin Cong was stunned by Zhang Fan. "Why not measure?" There was no way, Lin Cong wanted to ask a circuitous question, but Zhang Fan didn't get it.
Each has his own habits and his own hobbies. The most unbearable Zhang Fan on the operating table was being disturbed.
At first, this was a habit that Zhang Fan cultivated desperately for the sake of rut. People were disturbed on the operating table, just like Zhang Fan's food stamp was broken.
"Gibosn's surgery has been improved by Moore, and Moore's surgery has been improved by Dr. Shiji. Haven't you thought of continuing to improve! Doesn't measurement waste time?"
The tone is bland and the foreign language is not standard, but the meaning is too powerful, so powerful that Lin Cong can't speak, and the doctors who are powerful enough to stay in the video classroom have stayed.
Improvement, especially surgery, is easier said than done. Most of the surgeries that are popular today are almost how they were performed, and they are still almost how they are performed.
That is to say, except for the occasional one or two people with halo heads who dare to improve and reform, the rest mostly follow the rules, even if most of them do n’t learn well, it is not easy to improve.
"Improve? He wants to improve? How does he improve?"
One or two looked at the doctors next to him, all with question marks in their eyes.
After Dr. Wang heard Zhang Fan saying such awesome words, he almost threw all the hooks in his hands, which was too scary! ~
"Doctor Zhang, how is it improved here?" He couldn't hold back his doubts.
"Taking the acetabulum as the center point, establish a precise three radiating moment line in my mind, and the outer line is perpendicular to the long arm B-X line.
The test line sets the A1-B1 high eccentric moment perpendicular to the body.
The medial line is perpendicular to the pubic bone and lines A2-B.
Two points can fix a straight line, three points can fix a triangle, and the acetabulum, pelvis, and lower limbs are not exactly a triangle! "
Zhang Fan said while doing. This method is how many days he worked out in the system before he summarized it.
This method combined with MRI and CT of the patient can accurately locate the position of the hip joint.
To put it simply, to determine the start and end points of the bones, the position is directly fixed.
If this method is adopted, it will be very easy to change the hip surgery. However, this method has high requirements for the doctor's sense of space, the ability to calculate the torque, and the pressure load on the lower limbs.
To be honest, constructing a patient's accurate structural picture in the mind is not something that an average doctor can do.
With countless trainings and strict system requirements, Zhang Fan finally exercised his own surgical method through repeated failures.
His method is more accurate than the conventional surgical method. As long as it involves human factors, there are some errors, and Zhang Fan thus determines the position directly at the source. It can be said that as long as the material has not changed, he does There is no change in the operation, it is so accurate.
What's more, it saves time. It can reduce the wound exposure by at least half an hour, and how many half an hour is needed for the entire operation.
It is estimated that when a lot of people were still lush young people, that is, the little fart kid, they might have opened a mechanical alarm clock with a screwdriver. At that time, they might not be sighed by the fineness of the alarm clock.
In fact, the degree of sophistication of the human body is definitely much higher than the complexity and sophistication of human-made machines.
Moreover, the most important thing is that the organs of the human body have functions of self-recovery and self-regulation.
Others do not say, let's talk about people's feet, actually there are some surprises.
The upper limbs and lower limbs are actually different in length. If the length of the lower limbs is more than two centimeters, it will exceed the body's ability to compensate, and lameness will occur, and the so-called limping will be called walking.
There are three difficulties in hip replacement surgery. The most terrible one is the occurrence of uncontrollable fat embolism.
As the saying goes, eating meat is not as good as cheekbones, cheekbones are not as good as licking your fingers. This fragrance is because of a fat.
There is a large amount of fat in the bone marrow cavity, and the essence of the bone marrow is actually phospholipids, also known as fat.
Once this is turned on, a large amount of adipose tissue will liquefy, and then it will enter the blood. To be honest, according to the current medical level, it is unavoidable.
Fat embolism is one of the biggest uncertainties of orthopedic surgery. How terrible this uncertainty is. It can be said that once fat embolism enters more important organs, such as the lungs, to be honest, even if the patient is in the hospital, most of them are too late to be rescued.
In order to avoid it as much as possible, orthopedic surgeons try to speed up the operation and reduce injuries as much as possible, but orthopedic surgery is almost a destructive treatment, so it is very contradictory.
And Zhang Fan's method saves time, which means that his method is more likely to avoid fat embolism in patients.
Fan Zhang said while doing. Whether it's Dr. Wang on the operating table or the doctors in the classroom, the brain quickly wanted to repeat Zhang Fan's method.
Difficult, too difficult. Especially Dr. Wang, the sweat beads on the tip of the nose under the mask slowly leaked out.
It's too difficult, the brain is hurting, it's too difficult to copy.
"Prepare bone cement and shape it in two minutes." Zhang Fan did not stop. Say something to Dongshan girl near the operating table.
And Dongshan girl looked at Zhang Fan with a look of admiration. Although she couldn't understand what Zhang Fan said, she heard every word that Zhang Fan said clearly, but it was like a bunch of garbled characters. .
However, the girl from Dongshan just felt that Zhang Fan was very tall. She has gone to the operating tables of countless experts, and none of them made her feel that the surgery could be so simple, but also made people feel tall.
Especially when some doctors with bad skills were met, a measurement, to be honest, almost became an eye-target missile strike target.
With her eyes closed, she bent down and stared at the patient's leg. To be honest, sometimes she felt unreliable. Although Zhang Fan did not take measurements, she just made her feel reliable.
Perhaps this is the sixth sense of a woman.
The hip joint prosthesis is like a pistol or the upper end of the leg bones of the cheekbones.
When this gadget is installed, the prepared bone cement is first placed in the enlarged medullary cavity, and then inserted and fixed, so that the prosthesis and the bone are permanently adhered together.
Bone cement is not the kind of cement that is usually used to build a house. The bone cement used in the operating room solidifies very quickly. It will solidify in seven or eight minutes. It is slightly slower and the prosthesis cannot be placed.
So, when Mrs. Dongshan was going to prepare the bone cement, Dr. Wang was still gazing at God with an obsessed expression.
"Oh, how about it, figured it out? Very simple."
Zhang Fan asked with a smile like a demon.
"No!" Dr. Wang returned to his soul, and then asked very urgently.
When Zhang Fan said while doing it, he saw it. Zhang Fan didn't talk nonsense, he really improved the operation!
The doctors in the video classroom are not bad. As Zhang Fan's surgery continues, they also saw it. Zhang Fan improved the hip surgery.
Finally, Dr. Wang asked the questions in everyone's heart and the questions that everyone was very concerned about, "How did you do that?"
Dr. Wang looked at Zhang Fan longingly, just like the little baby looked at the other girl holding a popsicle but he didn't, looking at Zhang Fan longingly.
Just say one word: can you give me a break?
