Chapter 326: Bend it alive!

Chapter 326: I'm Bently Bent!
Other industries do not know, but as far as the medical field is concerned, what is the difficulty is to formulate a post-operative return visit and expected big data, but the human body is too complicated. Without a large experimental base, it is too remote to figure out the estimate. But this matter is too expensive, and there is no substantial economic benefit, so!
And the payback period in this industry is too long, at the youngest and most scarce time, you have to boil. Most industries also need to boil, but this industry has been boiled for a little too long. Five years of undergraduate, three years of transfer, and five years of hospitalization, this is still the smoothest, until the attending is considered a bit of a foundation, but during this time, a group of people boiled away.
Then a large number of medical students flooded the civil service, and some medical students went to work as pharmaceutical agents and other industries. No matter how much they hate or hate this industry, when the night is quiet, they will definitely miss him who once wore a white coat!
The sense of accomplishment between life and death is so beautiful! With each rescue, the adrenaline spiked like a roller coaster. Rob a man alive from the hand of death. Which feeling is really hearty, and this feeling is addictive.
"Director, prepare to bone graft." Zhang Fan opened his spinous process and turned to Lao Gao. With a small amount of bone defect, osteoblasts will gradually fill the defect. If such a defect is large, there is no way to fill it.
"Okay!" Lao Gao placed the automatic retractor. Just go to the sterile table next to the instrument nurse and start preparing the allogeneic bone needed for bone grafting.
For bone grafting, the best bone quality is actually the best of the patient's own bones, but Bart is too small to take it, and can only place allogeneic bones.
"Doctor Zhang, I'll wipe the blood for you." Although Zhang Fan was very accurate and gentle, but a lot of blood splashed on Zhang Fan's face and eyelids.
This operation is still a little better. If knee replacement is performed, flesh and blood will be called. Generally, when performing knee replacement, the surgeon must wear glasses like windshield glasses. Because it is necessary to cut the thickest femur of the human body, when the cutting machine cuts, bone marrow, blood, and a small amount of soft tissue directly splash out with the cutting machine.
The visiting nurse dipped in Xinjieer solution and gently wiped off the blood on Zhang Fan's face. "Okay, Dr. Zhang."
"Yeah!" Zhang Fan couldn't even thank him for saying that this kind of surgery was too damaging.
How exactly is this surgery done? In fact, it is also simple, that is, to separate the deformed bones that are connected up and down.
Then, adjust the position. Then fixed alloy instruments are placed from the upper and lower bone pieces. Then through this alloy instrument, the deformed spine was slowly corrected.
"The vertebral hook." Zhang Fan said to the surgical nurse after clearing the broken bone in the surgical area.
At this point in the operation, two hours had passed. Now is the time to place titanium instruments. Everything you do 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. If an error occurs at this time, the operation fails directly. There is no way to make up for it. The human spine is so big. Once there is an error, if you want to come back, it is dreaming.
The upper and lower spine, a few curved spines, begin to place correction instruments. What's the point, it's quite simple in popular terms, such as a curved sapling.
To correct it, first make a hole in a relatively straight place and put a nut with a hole. This nut is a pedicle hook. In turn, a hole with a hole is inserted at the interruption of the sapling, the lower end and the bottom, or It is also a hole in the ground.
Then use an iron rod through the hole at the upper end of the nut, insert it all the way to the ground, and then tighten the nut, so as the sapling grows, this curvature becomes smaller and smaller, and finally becomes straight.
"Director Wang, help me." Zhang Fan took the pedicle hook and placed it at Bart's pedicle. The vertebral hook is actually like a screw with a spiral, which is an expansion screw commonly used in peacetime, and then a buckle is attached to the top of the screw. A snap like a question mark.
The tool for placing this snap is like a corkscrew for red wine, but this one is not for pulling, but for drilling inward. "Doctor Zhang, let's get started." After Wang grasped the nail driver, he confirmed for Zhang Fan.
"Okay, I'm starting." One circle, two circles and three circles, the bone thickness is different, the number of circles is different, this is not wood or brick, can not be turned casually, after turning inside is the spinal cord.
One lumbar vertebra, two lumbar vertebrae, three lumbar vertebrae, all the way up to seven. Several thousands of such screws are imported. Titanium alloy, because this metal is relatively stable, it is not easy to cause electrolysis in the body, and it is not easy to be infected.
Putting on a good screw is not a very laborious task, but in this way, Zhang Fan's sweat has soaked in the hand-washing clothes. If it is not particularly thick, it is estimated that the surgical clothes are soaked.
Here comes the hardest work. Orthopedic implant rod, which is a straight titanium alloy rod. I don't know how much the hardness is, but this is the hardest metal Zhang Fan has ever seen.
Because the spine is originally radian, it is necessary to orthopedic implant rods to a certain radian, a specific radian, an radian that allows the spine to develop toward normal physiological curvature. Why are there a few other female surgeons? Orthopedics is very, very small, because orthopedic surgery is much more lively, not to mention women, men who are less physically fit and less powerful.
Orthosis is not a tall thing, especially this kind of metal orthosis, it is very simple, it is three fixed round iron pillars which are placed on top of an iron mule and forming a triangle.
"Dr. Zhang, let me do the orthopedics in the early stage. You can do the fine-tuning in the later stage. You have done more than two hours of surgery." Xu Xian said.
"It's okay. I'm here!" On the operating table, Zhang Fan was so alone. Don't talk about Xu Xian at this time, even if it is Lao Gao, Zhang Fan is not assured.
"You don't have to worry about it, he will not worry about anyone." Pharaoh understands Zhang Fan, doctors are like this, only you can be assured.
Zhang Fan held a titanium alloy rod about ten centimeters long and put it into the orthosis. Xu Xian grasped the orthosis with his hand, Zhang Fan held a bone-biting forceps in his left hand and a bone-biting forceps in his right hand, holding both ends of the titanium alloy.
"Have you caught it?" Zhang Fan asked Xu Xian.
"All right."
"Hey!" With Zhang Fan's dull sound coming out of the nasal cavity, the titanium alloy rod was visible to the naked eye and began to bend, and it was really bent to it.
This orthopedic is particularly strenuous. First of all, it must be corrected to a certain radian. Once the first radian is not reached, fine-tuning in the later stage will be more laborious.
It's too hard, it's too crooked, it's too small, and people don't move. And the number of orthopedics should not be too much, because the metal has a degree of fatigue, repeated violent orthopedics, although the naked eye can not see, in fact, the metal is no longer, after it is installed, the time is not long, broken!
So one-shot molding is best, which requires considerable familiarity with force control and knowledge of this material. Zhang Fanxi blushed and bent the titanium alloy rod at a stretch, and it was very beautiful, in line with the expected radian.
Zhang Fan took a slightly hot titanium alloy rod to make a gesture on the lumbar vertebra. Although the naked eye felt suitable, he still had to make a gesture. At this time, the mallets that are not directly attached are all mallets, but the mallet is estimated that this operation will not be performed.
Zhang Fan was making a gesture, and Xu Xian was frightened. "This guy isn't very strong. Why is he so strong. It's really a beast! Such a thick stick is in place for orthopedics. It seems that I have to go to the gym to get iron.
Lao Wang and Lao Gao are both blameless. Looking at Xu Xian a little stunned, Pharaoh grinned a bit, and then asked, "Xiao Xu, is there any object?"
"Oh! There is a director."
"You don't see Zhang Fan. The hairy boy is very powerful!"
"Eh!" Xu Xianhan came down. The operation went smoothly. Pharaoh couldn't help but want to talk. Zhang Fan was so annoying. He barely spoke from the operation and it was too difficult.
Zhang Fan glanced at Pharaoh, and he didn't squeak, the old man was sullen. The head nurse is a little emotional today. Otherwise, old men and young women can be annoying.
"Zhang Fan, do you see if it's suitable?" Lao Gao held the repaired allogeneous bone and handed it to Zhang Fan. Zhang Fan looked at him and said, "Just right." In normal times, Zhang Fan would definitely exaggerate, but as soon as he had surgery, Zhang Fan seemed to be in a different posture.
Zhang Fan took the allogeneic bone, then shook it by hand, screw by screw. Although he put it on himself, this final inspection must be indispensable. If you forget this step, well, it's time to torture after surgery.
It can be as long as one week and as long as one month. It is estimated that the screw can fall off every day.
"Implant the rod, fix it." Zhang Fan said so, several people involuntarily straightened their bodies, which was the most critical step in the operation. Fan Zhang gently inserted the orthopedic implant rod from the first fixed nut to the last nut, and the orthopedics was very successful, as if it was tailor-made for Bart.
Then turn the nut driver counterclockwise gently until the feel of the nut is in place, and then tighten it clockwise to prevent the nut from slipping. Tighten one by one, and finally you must push the implant rod card into the top of the hook with extra force.
OK, the placement of the implant rod is complete. Is this surgery done? No, that's half done. If you want to pull the deformed spine over, you have to use such instruments on both sides.
This is like a small curved tree. Pulling on one side can pull the degree of curvature, but there is also the risk of breaking the small tree. The best is to put one on the opposite side as well, to resist tension.
After putting the screws in, Zhang Fan determined it again, and then said to the Pharaoh, "Come to Director Wang, let's change the two positions." On the operating table, especially this kind of flat surgery, it is usually to help the surgeon. opposite.
Now we have to do the other side, so Zhang Fan has to change positions with Pharaoh. Pharaoh saw that Zhang Fan had fixed his position. He originally wanted to say, "Let me do it, but I glanced at Zhang Fan's six parents, who didn't recognize him. He looked like a wolf, and didn't speak."
Anyway, he is a director, so Zhang Fan refused, didn't he? So without talking much, he began to change positions with Zhang Fan.
For the doctor himself, this sterile area is actually defined as follows: below the neck, above the surgical gown straps are sterile areas, and hands to shoulders are sterile. Once you have surgery, whether you are contaminated or not, the rest of the area is considered a contaminated area.
What does a surgical gown look like? In fact, it is made of a raincoat with a particularly thick kind of cloth. When worn, it is the reverse 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, all of which are fixed by the cloth.
Generally speaking, do not move around as much as possible. If you have to change positions, you don't want to change at will. You must change positions back to back when you meet. Novice doctors are often scolded by operating room nurses in the operating room because they violate aseptic operation.
The position is fixed, and the fixation on this side is much faster. Repeating the above steps, the operation was finally fixed after four hours. Zhang Fan looked at the spine fixed by titanium alloy and smiled slightly.
Because he seemed to see Bart grow up. Strong and mountainous, with a straight back!
"Flush!" Xu Xian took over the position of Pharaoh and helped Zhang Fan to flush. With the last experience, Xu Xian no longer asked for sutures.
No need, I was thinking of replacing him, but this guy is afraid that he will grab the credit for it, and he won't even let the stitching, stingy! Xu Xian glanced at Zhang Fan and slandered in his belly.
Outside the operating room, Bart's mother and grandmother silently thought, looking forward, Bart's father kept walking in the corridor. Check the time on your phone from time to time.
This mood is especially parenting. Really, it's not ordinary anxiety. For a while I was expecting the operation to be successful, and the children would jump out. For a while, I was worried that the operation would fail. What should they do? Their hearts would feel like shrinking together, and they wouldn't dare to breathe. Worried about affecting doctors who perform operations in the operating room.
"Bart's family!" The head nurse was much better now. After the operation is completed, inform the family that this is usually the job of a little nurse. Today she rushed to do it.
"I am! I am!" Dad Bart rushed forward.
"I'm Bart's mother! Doctor, I'm his mother." Bart's mother, who was sitting on the stool for a long time, hurried over.
"Bart's operation is done. The operation was very successful. This will already be sent to the ICU. You can go to visit at a specified time tomorrow morning." After that, he added: "Relax! It's okay."
Just like that, let Bart's parents hang in the air. "Thank you! Thank you! Doctor, thank you!"
"I'm a nurse. Don't hesitate. Keep your voice down. There are others in the operation. Come on, go." The nurse entered the operating room. Footsteps lightly returned to the operating room.
"Bart has finished the operation. Let's go back." The old grandmother with her back of ears, the rosary in her hand fell to the ground, her toothless lips pinched at Bart's parents, and Bart's mother supported her mother-in-law and said A sentence.
"Finished? Bart, 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 wife said it again.
The anxious old lady murmured with tears, and grasped Bart's mother desperately for her grandson.
"Mom, I really don't lie to you!"
