The reading light was very bright, and Takahashi watched it for a long time, but he didn't see the dead bones that Yang Ping said.

Yang Ping has pointed out that there is a slight abnormality in that part, but in Takahashi's understanding, that is, vascular indentation, a typical vascular indentation, how can it be regarded as dead bone, obviously dead bone and vascular indentation are two unrelated concepts, and now they are put together to become a differential diagnosis.

Staring at the bright light for too long, Takahashi's vision began to blur, his eyes were sore, and tears were forced out, and he had to look away for a while. The eyes looked away, and the field of vision was full of light spots, and everyone was flashing and flashing.

"This kind of high-level skill is not something that can be mastered in a while, even if Dr. Yang points to the mosquito and says, it is the male genitalia, this is the female genitalia, we can't tell the difference, we will study it slowly when we have time." Song Zimo put the film away temporarily.

This surgery seems simple, but it is actually quite difficult to operate.

The key is positioning, without the help of a navigation system, relying on the doctor's operating experience, to open a window at the lower end of the right tibia, and then dig up a large piece of bone tissue, it is possible to dig out the infected dead bone.

The dead bones of this infection must be thoroughly dug up, as long as a little is left, it is equivalent to leaving the source of infection, and after a period of time, the infection will recur, and the previous efforts will be in vain.

Therefore, when digging up dead bones, it is necessary to dig out some of the surrounding normal bone tissue together to ensure thoroughness.

This operation is like digging a sweet potato, a sweet potato is buried in the soil, buried very deeply, and open surgery is equivalent to digging a big pit and finally digging out the sweet potato.

Minimally invasive surgery is equivalent to using a hollow bamboo tube, inserting it into the soil, knocking it in, inserting it to a certain extent and then pulling it out, the bamboo tube is filled with soil, and the sweet potato is in the bamboo tube at this time.

"Do you want to use the Dimensity surgical robot and make an appointment with the operating room there in advance?" Song Zimo felt that such a small dead bone, millimeter-level, without the assistance of navigation technology, it was difficult to complete minimally invasive surgery.

The Dimensity surgical robot comes with its own navigation equipment, and the accuracy of navigation can reach 0.8 mm.

If the robot is used for this operation, the child will have to do the CT again, import the CT data into the navigation system of the surgical robot, and use the robot's CT scan to locate the operation, and the child will naturally eat a lot of rays.

"I watched the child's X-ray and CT do a lot, forget it, and then use the robot to navigate, the child has to eat rays again, try to simplify, in our operating room, I'll do it." Yang Ping looked at the big bag of images and pictures, and ate a lot of rays for this sick child, which can reduce the radiation as much as possible.

"Today, I will schedule the operation, rush to the table, do it under local anesthesia, let him be discharged from the hospital tomorrow, and he will not participate in strenuous exercise for three months." Yang Ping explained to Song Zimo that for him, this operation was too simple.

"It's that simple?"

The child's father thought he had misheard, and he had the impression that after the operation, he would recuperate at home for at least a month, and he would have to hold on crutches for three months, and he was ready to take a long vacation.

I was going to bring it to the doctor during the summer vacation, but the child cried pain every night during this time, especially in the last few days, and the pain was so painful that he couldn't sleep, not like he was pretending.

There was no way, the father took the child to the community health station to see, and the doctor at the health station suggested that he go to Sanbo Hospital to see.

When I arrived at Sanbo Hospital, I didn't see Dr. Yang's outpatient department, so I hung up the number of an orthopedic outpatient doctor, the doctor said that it was an incurable disease, and he had to say that he was hospitalized for diagnosis and treatment, and his father appointed Dr. Yang for diagnosis and treatment, and the child received a comprehensive orthopedic department.

Hearing the words incurable disease, the child's parents were scared and their hearts were pounding, it wouldn't be a big deal, right?

Now listening to Yang Ping say this, he will be discharged from the hospital the next day after doing it, and he can walk normally immediately without crutches.

What I thought was particularly troublesome is now easier than circumcision, and circumcision requires gritting your teeth and walking for a few days.

Preoperative talks, signing, and a series of preoperative preparations are done, and the operation is lined up at the back.

"No navigation? Okay—no?" Xu Zhiliang asked.

Song Zimo didn't doubt it: "You haven't been here for a long time, you will slowly adapt to it in the future, Dr. Yang is a person who keeps creating miracles, he will help you expand your brain, keep expanding." ”

After checking the room, except for those on duty, they all went to the operating room, and after a few surgeries, it was the child's turn to operate, Song Zimo took Xiaowu to disinfect the sheet, and according to Yang Ping's requirements, the local anesthesia of the surgical site was also done.

Takahashi borrowed a magnifying glass from a student, pointed at the reading lamp, and used the magnifying glass to read the film, his nose almost against the magnifying glass, looked at it for a while, rubbed his eyes, and continued to watch.

Yang Ping washed his hands and dressed, pondered for a while on the film, made one last positioning in his heart, and then started his work.

On the medial skin of the lower end of the right tibia, he made a 1 cm longitudinal incision to the periosteal bone, separated from the periosteal layer, and then used vascular forceps to open a small incision to expose a small part of the medial tibia.

Hold the ring drill against the bone surface, adjust the direction, and then slowly drill in, stop at a certain depth, and then pull out the ring drill with stuffed bone.

In the irrigation area, calcium sulfate containing vancomycin is adjusted into a dough and fills the small tunnel that has just been dug, and vancomycin can be slowly released locally to kill bacteria that may remain inside.

The tunnel is plugged steadily, a small incision of 1 cm, only one needle, starting from the periosteum, layered sutures, a small sterile dressing is covered on, and the work is called!

From the stage to the sewing of the skin, one minute and twenty-two seconds, Takahashi timed, and it was solved?

"Perspective?" Yang Ping took off his surgical gown and gloves.

Fluoroscopy is only a brief exposure, and the amount of radiation is much less than multiple or continuous exposures for navigation surgery.

After the perspective, the preoperative image pictures, the tunnel drilled by the ring drill, just at the point that Yang Ping said, the point just encircled, no more, no less.

Song Zimo took out the cylindrical bone tissue in the ring drill, and the cylindrical bone tissue, except for a small amount of cortical bone at one end, is mostly cancellous bone.

He then carefully cut the cylinder into round slices, and it was not difficult to cut the cancellous bone, and sure enough, he looked at the section of the lesion.

The profile is sandwich-like, with a dead bone the size of a grain of rice in the center, surrounded by infected bone tissue, and beyond that is a ring of normal bone tissue.

Looking at this profile, Song Zimo can be completely sure that the lesion has been completely removed, and the accuracy of this positioning is higher than that of the surgical robot.

"I'll do a CT after the surgery." Yang Ping commanded.

Postoperative CT scans are unavoidable, and evidence must be left to confirm that the lesion has been completely removed.

"Keep it as a specimen and send it to the pathology department for pathological examination, I want to go to the pathology department and go down to the microscope to see it in person, are you interested?" Song Zimo put a few thin slices into the specimen bag for the examination.

"Wait! Show me. Gao Qiao was still struggling just now, how Yang Ping did it, without the help of the navigation system, to accurately take the lesion at one time.

Song Zimo gave the specimen bag to Zhou Can: "Wait for the pathology department, let's go to the microscope and take a slow look, sandwich the lesion, and remove it accurately." ”

The child followed the doctor out of the operating room, and Song Zimo told his parents that he could walk normally, that strenuous physical exercise would be prohibited for three months, that he would be discharged from the hospital tomorrow and go to school normally, that he would change the medicine once every three days and remove the stitches in 10 days.

"It's a lesion that was dug up, there are dead bones, there's infected bone tissue, you see." Song Zimo showed the picture of the mobile phone to the child's father.

The child's father couldn't understand it, but he could understand that this was the root of the disease, and now the doctor has dug up the root of the disease with a pair of skillful hands.

"If you dig a bone, will it hurt?" The child's father asked worriedly.

"There are very few pain nerves in the bone tissue, so I don't feel too much pain, and if it hurts, it is also a pain in the wound, and I will give a little painkiller at night." Song Zimo explained.

"Will the hole you dug be filled later?"

"It's usually filled with new bone tissue after three months."

"I dug up the roots this time, so I won't recur, right?"

"Not normally, but no one can guarantee 100 percent."

"What should I pay attention to in terms of diet, and what should I avoid in terms of food? Or what is good for his long bones? Is it OK to make bone broth? ”

"Just eat normally, if you like to drink bone broth, just give it to him, there is no benefit to this disease, and there is no harm."

"Can you make some Tian Qi soup? Promote blood circulation and eliminate blood stasis! ”

The child's father and Song Zimo asked and answered, these questions had been communicated in detail before the operation, and now the child's father took them out and asked them again.

"Tian Qi is a traditional Chinese medicine, don't eat it casually, just eat normally, your family's normal diet, it's okay to eat Tian Qi every day?" Zhang Lin was impatient to listen to it, and interjected.

"Can you send me a copy of the photo?" The child's father was embarrassed by Zhang Lin and changed the subject.

Song Zimo gave him a copy of the photo, and the father was very positive, so he took the photo and immediately posted it to Moments: The root of the child's illness has finally been dug up, and he can sleep peacefully tonight.

Trouble came, and as soon as the child's father's circle of friends was released, many people responded one after another, asking which hospital to go to and which doctor to find.
