Other industries don't know, but as far as the current medical field is concerned, what is the difficulty, that is, the formulation of big data for a postoperative return visit and expectations, but the human body is too complex. Without a large-scale test base, it is too unlikely to figure out the estimate. But this thing is too expensive, and there is no substantial economic benefit, so!

And the payback period of this industry is too long, and you have to survive when you are the youngest and most short of money. Most industries also need to survive, but the time for this industry to stay up is a bit too long. Five years of undergraduate, three years of transfer, five years of hospitalization, this is still the smoothest, and it is a bit of a foundation to survive until the main treatment, but during this time, a group of people have been boiled away.

Then a large number of medical students flooded the civil service, and some medical students went to work as drug agents and other industries. No matter how much they hate or hate this industry, in the dead of night, they will definitely miss him who used to be wearing a white coat!

The sense of accomplishment between life and death is so beautiful! Every time I am rescued, the adrenaline rush is like a roller coaster. Snatch a man alive from the clutches of death. What kind of feeling, really hearty, and this feeling is addictive.

"Director, prepare for bone grafting. After Zhang Fan split the spinous process, he turned his head and said to Lao Gao. If there is a small amount of bone defect, osteoblasts will slowly fill the defect, and if there is such a large defect, there is no way to fill it.

"Okay!" after Lao Gao placed the automatic puller. Go to the sterile table next to the instrument nurse and start preparing the allogeneic bone needed for bone grafting.

Bone grafting, the best bone is actually the patient's own bone is the best, but Bart is too small to take it, so he can only place allogeneic bone.

"Dr. Zhang, I'll wipe your blood. Although Zhang Fan's splitting was very accurate and gentle, there was still a lot of blood splashed on Zhang Fan's face and eyelids.

This kind of surgery is slightly better, if you do knee arthroplasty, it is called flesh and blood, and generally when you do knee arthroplasty, the surgeon must wear glasses like windproof glasses. Because the thickest femur of the human body is to be cut, when the cutter cuts, the bone marrow, blood, and a small amount of soft tissue are directly splashed out with the cutter.

The itinerant nurse dipped the new Jie'er solution and gently wiped the blood stains off Zhang Fan's face, "Okay, Doctor Zhang." ”

"Hmm!" Zhang Fan didn't even bother to say thank you, this kind of surgery is too damaging, and he must hurry up the operation time.

How exactly does this surgery work, in fact, it is also very simple, that is, the deformed bone pieces connected to the upper and lower parts are separated first.

Then, adjust the position. A fixed alloy instrument is then placed from the upper and lower bone pieces. Then the deformed spine is slowly corrected through this alloy instrument.

"Vertebral root hook. After Zhang Fan cleaned up the broken bones in the surgical area, he said to the operating nurse.

At this point, two hours have passed. Now it's time to place the titanium instruments, and everything that is done at this time has to be determined three times.

Because at this time, once the device is implanted, there is no way to modify it. At this time, if there is a mistake, the operation will fail directly. There is no way to make up for it, the human spine is so big, once something goes wrong, if you want to start again, what is a dream.

Upper and lower spines, bent several spines, begin to place orthotic instruments. What does it mean, in layman's terms, it's quite simple, like a curved sapling.

To correct it, first punch an eye in a relatively straight place, put in a nut with holes, this nut is a vertebral root hook, and then make a nut with holes at the break, lower end, and bottom of the sapling, or directly make a hole hole in the ground.

Then use an iron rod to pass through the hole at the top end of the nut from the top end to the ground, and then tighten the nut again, so that as the sapling grows, the curvature becomes smaller and smaller, and finally becomes straight.

"Director Wang, help me support me. Zhang Fan took the vertebral root hook and placed it at the pedicle of Bart. The root hook is actually like a screw with a spiral, which is the expansion screw commonly used in daily life, and then a buckle is attached to the top of the screw. It's like a snap like a question mark.

The tool used to place this buckle is like a wine opener, but this one is not used to pull out, but to drill inside. "Dr. Zhang, let's get started. After Lao Wang grabbed the nail beater, he confirmed it for Zhang Fan.

"Okay, here I go. "One circle, two circles, three circles, the bone thickness is different, the number of circles is different, this is not wood or brick, you can't turn it casually, and if you turn it through, it's the spinal cord.

One lumbar vertebrae, two lumbar vertebrae, three lumbar vertebrae, all the way up to seven. One such screw, imported in the thousands. Titanium alloy, because this metal is relatively stable, it is not easy to electrolyze in the body, and it is not easy to be infected.

Put on the screws, this is not a very laborious job, but just like that, Zhang Fan's sweat has soaked through the hand clothes, if it weren't for the fact that the surgical gown is particularly thick, it is estimated that the surgical gown would be soaked.

The most strenuous work is coming. The orthopedic implant rod is a straight titanium alloy rod. I don't know how much hardness there is, but this is probably the hardest metal Zhang Fan has ever seen.

Because the spine is originally curved, now the implant rod needs to be orthopedic to a certain curvature, a specific curvature, a curvature that allows the spine to develop towards a normal physiological curvature. Why are there still a few other female surgeons, orthopedics is indeed very, very few, because there are a lot of jobs in orthopedic surgery, not to mention women, men with a little less strength in their bodies can't do it.

The orthosis is not a tall thing, especially this metal orthosis, which is very simple, three fixed round iron pillars placed on top of an iron lump in a triangular shape.

"Dr. Zhang, I'll do the orthopedics in the early stage, and you will do the fine-tuning in the later stage, and you have done more than two hours of surgery. Xu Xian spoke.

"It's fine. I'm coming!" On the operating table, Zhang Fan is too lonely, don't talk about Xu Xian at this time, even if he is old, Zhang Fan is not at ease.

"Leave it alone, it'll make him feel sorry for anyone. Lao Wang understands Zhang Fan, doctors are like this, and only those who do it themselves will be relieved.

Zhang Fan took a titanium alloy rod about a dozen centimeters long and put it into the orthosis. Xu Xian grabbed the orthosis with his hands, Zhang Fan had a rongener in his left hand and a rongeur in his right hand, clamping the two ends of the titanium alloy.

"Have you caught it?" Zhang Fan asked Xu Xian.

"Alright. ”

"Hey!" With Zhang Fan's dull sound from his nasal cavity, the titanium alloy rod began to bend visibly with the naked eye, and it was really bent alive.

This kind of orthopedic is particularly strenuous. First of all, it is necessary to correct to a certain arc, once the first time does not reach the expected curvature, it will be more laborious to fine-tune it later.

The strength is too big, the break is too bent, the strength is small, and people don't move at all. And the number of orthopedics can not be too much, because metal has a fatigue degree, repeated violent orthopedics, although the naked eye can not see, in fact, the metal is no longer good, after installation, the time is not long, broken!

Therefore, it is best to mold in one go, which requires a considerable familiarity with the power control and the level of knowledge of the material. Zhang Fan blushed, and bent the titanium alloy rod in one go, and it was very beautiful, in line with the expected arc.

Zhang Fan held a little hot titanium alloy rod and compared it on the lumbar spine, although it felt appropriate to the naked eye, but it still had to be compared. At this time, it is not a good mallet to be installed directly, but it is really a great mallet, and it is estimated that this operation will not be done.

Zhang Fan was gesturing, and Xu Xian was directly stunned. "This guy isn't very strong, why is he so strong. It's a real brute! Such a thick rod puts the orthopedic in place at once. Looks like I'm going to have to go to the gym in the future. ”

Lao Wang and Lao Gao were not surprised, looking at Xu Xian a little stunned, Lao Wang smiled evilly, and then asked, "Xiao Xu, do you have a partner?"

"Oh! ”

"You see Zhang Fan doesn't have it, the hairy boy is strong!"

"Huh!" Xu Xian Khan came down. The operation went well, Lao Wang really couldn't help but want to speak, Zhang Fan was so annoying, he almost didn't speak from the operation, it was too difficult.

Zhang Fan glanced at Lao Wang, he didn't squeak, the old man was sullen. The head nurse is a little emotional today, otherwise the old man and the young woman will be annoying to death.

"Zhang Fan, do you see if it's appropriate. Lao Gao took the repaired allogeneous bone and handed it to Zhang Fan. Zhang Fan looked at it and said, "It's just right." "If it was usual, Zhang Fan would definitely praise it, but as soon as he had surgery, Zhang Fan seemed to have changed into a posture that people should not enter.

Zhang Fan took the allogeneic bone, and then shook it gently with his hand one by one, although he went on it himself, but this final inspection must not be missing. If you forget this step, well, the time for torture is the surgery.

As little as a week, as long as a month, it is estimated that I can dream every day that the screws fall off.

"On the implant stick, fixed. As soon as Zhang Fan said this, several people involuntarily straightened their bodies, which was the most critical step in the operation. Zhang Fan gently snapped into the orthopedic implant rod from the first fixing nut, and stuck it until the last nut, and the orthopedic was very successful, as if it was specially tailored for Bart.

Then gently and steadily turn the nut driver counterclockwise until the nut is in place, and then tighten it clockwise, which is to prevent the nut from slipping. Tighten them one by one, and finally you have to push the implant stick card into the top of the hook with extra force.

OK, the implant is done, is this surgery done? No, this is only half done. In order to pull the deformed spine over, such an instrument must be inserted into both sides.

This is like a curved tree, pulling on one side can pull this curvature over, but there is also a risk of breaking the tree. The best thing is to put one on the opposite side as well, which is used to fight the pull.

After putting on the screws, Zhang Fan confirmed it again, and then said to Lao Wang: "Come to Director Wang, let's change positions." "On the operating table, especially for this kind of flat surgery, it is usually a suke standing opposite the operator.

Now I want to do the other side, so Zhang Fan wants to change positions with Lao Wang. Lao Wang saw that Zhang Fan had set his position, and he originally wanted to say: Come and I'll do it, but after seeing Zhang Fan's six relatives and not recognizing him, he didn't open his mouth like a wolf.

It's a director anyway, and he asked Zhang Fan to refuse, isn't he ashamed. So he didn't say much, and began to change positions with Zhang Fan.

For the doctor himself, this sterile area is actually defined as follows: below the neck, above the gown tie is the sterile area, and the hands to the shoulders are sterile. Once you have surgery, the rest of the area is considered a contaminated area, regardless of whether you are contaminated or not.

What is the surgical gown, in fact, it is made of a particularly thick fabric to make a raincoat-like shape, and when it is worn, it is the opposite of the raincoat, that is, the side of the raincoat with buttons is on the doctor's back. However, there are no buttons on the surgical gown, and it is all fixed with cloth straps.

Generally, the surgery is to try not to move, if you have to change the position, it is not at random, you must change the position back to back when the two meet. Novice doctors are often scolded by the nurses in the operating room for violating aseptic procedures.

The position is fixed, and the fixation on this side is relatively much faster. The above steps were repeated, and the operation was finally completed after four hours. Zhang Fan looked at the spine fixed by titanium alloy and smiled lightly.

Because he seems to have seen Bart grow up. Strong as a mountain, with a straight back!

"Rinse!" Xu Xian took over Lao Wang's position and helped Zhang Fan rinse, with the experience of the last time, Xu Xian no longer asked for stitches.

There's no need, I want to replace him, but this guy is afraid that he will take credit, so he won't even let him stitch up, stingy! Xu Xian glanced at Zhang Fan and sneered in his stomach.

Outside the operating room, Bart's mother and grandmother silently read and looked forward to Bart's father walking around the corridor. Check the time on your phone from time to time.

This mood, especially for parents. Really, not your average anxiety. One time they look forward to the success of the operation, and the other time they are worried about the failure of the operation, what they will do. Their hearts will seem to shrink together, and they will not dare to take a big breath. I am afraid that it will affect the doctors who perform the surgery in the operating room.

"Bart's family!" the head nurse was much better at this time. After the operation, she had to inform the family that this was usually the work of a little nurse, and she rushed to do it today.

"I am, I am!" Father Bart strode over.

"I'm Mother Bart! Doctor, I'm his mother. Bart's mother, who had been sitting on the stool for a long time, stumbled over.

"Bart's surgery is done, the operation is successful, this will be sent to the ICU, you can go to visit someone tomorrow morning at the appointed time. After speaking, he added: "Don't worry! It's okay." ”

Just one sentence made Bart's parents' hearts hanging in mid-air fall to the ground. "Thank you, thank you, doctor!"

"I'm a nurse, you're welcome, keep your voice down, there's someone else operating. Alright, let's go. The nurse went into the operating room. I walked back to the operating room with light steps.

"Bart is done. Let's go back. The old grandmother with her ears behind her ears fell to the ground with the rosary in her hand, and her toothless lips trembled and looked at Barth's parents, and Barth's mother helped her mother-in-law and said.

"It's done, what about Nabat, why didn't you come out, don't fool me, my grandson. The old lady watched the nurse come out and go in, and now the daughter-in-law said the same thing.

The anxious old lady shed muddy tears, clutching Bart's mother to her grandson.

"Mom, I really don't lie to you!"
