Chapter 326

Other industries do not know, but at present, in the medical field, what is the difficulty, that is, the formulation of a postoperative return visit and expected big data, but the human body is too complex. Without a large test base, it is impossible to make a clear estimation. But this matter is too expensive, and there are no substantive economic benefits, so!

And the return period of this industry is too long. You have to endure when you are the youngest and most short of money. Most industries also need to endure, but this industry has endured for a little too long. Five years of undergraduate education, three years of transfer and five years of hospitalization are the most smooth. It's not until you're in charge of the treatment that you have a little foundation, but during this time, you've gone through a group of people.

Then a large number of medical students filled the civil service, and some medical students worked as drug agents and other industries. No matter how much they hate or hate this industry, they will definitely miss him who once wore a white coat in the dead of night!

The sense of achievement between life and death is so beautiful! Every rescue, adrenaline soared like a roller coaster. Snatch a man alive from death. What kind of feeling is really hearty, and this feeling is addictive.

"Director, prepare the bone graft." After splitting the spinous process, Zhang Fan turned his head and said to Lao Gao. For a small amount of bone defects, osteoblasts will slowly fill the defects. If such a large defect is like this, it can't be filled.

"Good!" After Lao Gao has placed the automatic puller. Go to the sterile table next to the instrument nurse and start preparing the allogeneic bone for bone grafting.

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

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

This kind of operation is a little better. If you do knee arthroplasty, it is called flesh and blood. Generally, when you do knee arthroplasty, the operator must wear glasses like windproof glasses. Because it is necessary to cut the coarsest 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 itinerant nurse dipped in Bromogeramine solution and gently wiped the blood off Zhang Fan's face, "OK, Doctor Zhang."

"Yes!" Zhang fan can't even thank you. He said that the injury of this operation is too great. We should hurry up the operation time.

How is this operation done? In fact, it is also simple, that is, to separate the deformed bone blocks connected up and down first.

Then adjust the position. Then place the fixed alloy instrument from the upper and lower bone blocks. Then slowly correct the deformed spine through this alloy instrument.

"Vertebral root hook." After cleaning up the broken bones in the operation area, Zhang Fan said to the operation nurse.

Two hours have passed since the operation. Now is the time to place titanium instruments. Everything done at this time must 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. There is such a big place in the human spine. Once there is a mistake, if you want to start again, it is not a dream.

The upper and lower spine, several bent spines, began to place corrective instruments. What does it mean? It's quite simple in popular terms, such as a curved sapling.

To correct it, first drill a hole in a relatively straight place and put a perforated nut, which is the vertebral root hook. In turn, drill a perforated nut at the interruption, lower end and bottom of the sapling, or directly drill a hole on the ground.

Then use an iron rod to pass through the hole at the upper end of the nut from the top to the ground, and then tighten the nut. In this way, with the growth of the saplings, the curvature becomes smaller and smaller, and finally becomes straight.

"Director Wang, help me." Zhang Fan took the vertebral root hook and placed it at Bart's pedicle. The vertebral root hook is actually like a screw with a screw. What kind of expansion screw is commonly used in peacetime, and then a buckle is connected at the top of the screw. Like a question mark.

The tool for placing the buckle is like a bottle opener for red wine, but it is not used to pull out, but to drill into it“ Doctor Zhang, all right, let's start. " Lao Wang grabbed the nailer and confirmed it for Zhang Fan.

"OK, I'll start." One circle, two circles and three circles. The thickness of bone is different and the number of circles is different. This is not wood or brick. You can't turn it casually. If you turn it through, it's the spinal cord.

One lumbar vertebra, two lumbar vertebrae and three lumbar vertebrae have been on seven. Such a screw is imported in thousands. Titanium alloy, because this metal has relatively stable properties, it is not easy to electrolyze in the body and is not easy to infect.

Screw up the screws. It's not a hard job, but in this way, Zhang Fan's sweat has been soaked in his hand washing clothes. If the surgical clothes were not particularly thick, it's estimated that the surgical clothes would be soaked.

Here comes the hardest work. The orthopedic implant rod is a straight titanium alloy rod. I don't know how hard it is, but it's probably the hardest metal Zhang Fan has ever seen.

Because the spine originally has radians, now we should straighten the implant rod to a certain radian, a specific radian, an radian that can make the spine develop towards normal physiological curvature. Why are there several other female surgeons? Orthopedics is really very, very few, because orthopedic surgery has a lot of work, not to mention women. Men with poor body and less strength can't do it.

Orthosis is not a tall thing, especially this kind of metal orthosis, which is very simple. It is three triangular fixed circular iron pillars placed on an iron lump.

"Dr. Zhang, I'll do the early orthopedics. You can do the fine-tuning later. You've had surgery for more than two hours." Xu Xian spoke.

"It's all right. I'll come! " On the operating table, Zhang Fan is too independent. Don't talk about Xu Xian at this time. Even Lao Gao, Zhang Fan is not at ease.

"Leave it alone. He won't trust anyone." Lao Wang understands Zhang Fan. Doctors are like this. Only what they do can they rest assured.

Zhang Fan took a titanium alloy rod about ten centimeters long and put it into the orthosis. Xu Xian grasped the orthosis with her hand. Zhang Fan had 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 got it?" Zhang Fan asked Xu Xian.

"All right."

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

This kind of orthopedic is very laborious. First, straighten to a certain radian. Once the expected radian is not reached for the first time, it will be more laborious to fine tune in the later stage.

It's too hard. It's too bent. It's too hard. People don't move. And the number of orthopedics can't be too many, because the metal has a degree of fatigue. Repeated violent orthopedics can't be seen by the naked eye. In fact, the metal can't be used anymore. After it is installed, it won't take long to break!

Therefore, one-time molding is the best, which requires considerable familiarity with force control and understanding of this material. Zhang Fan blushed and bent the titanium alloy rod in one breath, which was very beautiful and in line with the expected radian.

Zhang Fan holds a little hot titanium alloy rod to draw on the lumbar spine. Although it feels appropriate to the naked eye, he still needs to draw. At this time, the hammers are installed directly without comparison, but it is estimated that the operation will not be done.

When Zhang Fan was making a gesture, Xu Xian was stunned directly“ This guy is not very strong. Why is he so strong. The real animals! Such a thick stick can be straightened in place at once. It seems that I have to go to the gym to roll iron in the future. "

Lao Wang and Lao Gao were surprised. Looking at Xu Xian, Lao Wang was a little stunned. Lao Wang smiled and asked, "Xiao Xu, do you have an object?"

"Oh! With the director. "

"You see, Zhang Fan doesn't. The Hairy boy has strong firepower!"

"Well!" Xu Xianhan came down. The operation went well. Lao Wang couldn't help but want to talk. Zhang Fan was so annoying that he hardly spoke from the operation. It was too hard.

Zhang Fan glanced at Lao Wang and said nothing. The old man couldn't be coquettish. The head nurse is a little excited today. Otherwise, old men and young women can be annoying to death.

"Zhang Fan, see if it's appropriate." Lao Gao handed the repaired allogeneic bone to Zhang Fan. Zhang Fan looked and said, "just right." If at ordinary times, Zhang Fan absolutely wants to boast, but once he has an operation, Zhang Fan seems to have changed his posture of not entering strangers.

Zhang Fan took the allogeneic bone, and then shook it gently with his hands one by one. Although he did it himself, this final examination must not be missing. If you forget this step, well, surgery is the time to torture.

At least a week, as long as a month, it is estimated that you can dream every day that the screw falls off.

"Install the implant rod and fix it." Zhang Fan said that several people could not help straightening their bodies, which was the most critical step of the operation. Zhang Fan gently stuck the orthotic implant rod from the first fixed nut to the last nut. The orthotics was very successful, as if it was specially tailored for Bart.

Then gently and steadily turn the nut driver counterclockwise until the hand feels that the nut is in place, and then tighten it clockwise to prevent the nut from sliding. Tighten one by one, and finally push the implant rod clip into the top of the hook with additional force.

OK, the placement of the implant rod is completed. Is the operation finished? No, that's half done. To pull the deformed spine over, such instruments must be inserted into both sides.

This is like a curved small tree. Pulling on one side can pull the bending degree, but there is also a risk of breaking the small tree. The best thing is to put one on the opposite side to resist the tension.

After fixing the screw, Zhang Fan confirmed it again, and then said to Lao Wang, "come to Director Wang, let's change our positions." On the operating table, especially this kind of plane surgery, one assistant usually stands opposite the operator.

Now we have 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. He wanted to say: let me do it, but he looked at Zhang Fan and refused to recognize him. He looked like a wolf and didn't speak.

At least it's a director. He asked Zhang Fan to refuse. Isn't he ashamed. So I didn't talk much, so I began to change positions with Zhang Fan.

For the doctors themselves, this sterile area is actually stipulated as follows: the sterile area below the neck, above the surgical garment lace, and the sterile area from hands to shoulders. Once you have the operation, whether you are polluted or not, the rest is regarded as a polluted area.

What is the operation suit like? In fact, it is made of a particularly thick cloth into the shape of a raincoat. When wearing it, it is opposite to the raincoat, that is, the button side of the raincoat is on the doctor's back. But there are no buttons on the surgical clothes. They are all fixed by cloth belts.

General surgery is to try not to move around. If you have to change the position, you must change the position back to back when they meet. Novice doctors are often scolded by nurses in the operating room for violating aseptic operation.

The position is fixed, and the fixing on this side is much faster. Repeat the above steps. After four hours, the operation was finally fixed. Zhang Fan looked at the spine fixed by titanium alloy and smiled gently.

Because he seemed to see Bart grow up. Strong as a mountain, straight back!

"Flush!" Xu Xian took over Lao Wang's position and helped Zhang Fan wash. With the last experience, Xu Xian no longer asked for stitching.

It's not necessary. He wants to replace him, but this guy is deeply afraid of taking credit for himself. He won't even let the suture. He's stingy! Xu Xian glanced at Zhang Fan and feigned in his stomach.

Outside the operating room, Bart's mother and grandmother read silently and looked forward to it. Bart's father kept walking in the corridor. Look at the time on your mobile phone from time to time.

This mood, especially for parents. Really, not ordinary anxiety. One is looking forward to the success of the operation, the child can jump out, the other is worried about the failure of the operation, what should they do. Their hearts would be like shrinking together, and they didn't dare to breathe. I'm afraid it will affect the doctors in the operating room.

"Bart's family!" The head nurse is much better now. After the operation, we should inform the family members that this is usually the work of a small nurse. Today, she rushed to do it.

"I am! I am! " Bart's father strode over.

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

"Bart's operation has been completed. The operation is very successful. It has been sent to the ICU. You can visit a person at the specified time tomorrow morning." Then he added, "don't worry! It's okay. "

In this sentence, Bart's parents fell to the ground in mid air“ thank you! Thank you! Thank you, doctor! "

"I'm a nurse. You're welcome. Keep your voice down. There are others undergoing surgery. All right, go. " The nurse entered the operating room. Light footed back to the operating room.

"Bart has finished the operation. Let's go back. " The old woman with ears on her back dropped her rosary beads to the ground. Her toothless lips trembled and looked at Bart's parents. Bart's mother held her mother-in-law and said.

"Done? Where's Bart? Why didn't he come out? Don't deceive me! Where's my grandson. " The old lady watched the nurse come out and go in, and now her daughter-in-law said so.

The anxious old lady, with muddy tears, grabbed Bart's mother and desperately wanted her grandson.

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