Back in the ward, Cui Xubing's wife Guo Liu quietly asked: "How was it?"
Cui Xubing responded with a mysterious smile: "It's done."
The couple felt relieved, otherwise they were afraid that the child's surgery would be performed by an intern. For such an important surgery, if an intern performed the surgery, even if it was completed successfully, the best results would not be achieved.
I don’t know where they heard the gossip, saying that if they don’t feel comfortable with it, the surgery will be done by interns.
In fact, which hospital interns can perform surgeries?
Looking around the country, I'm afraid I can't find a hospital that allows interns to perform surgeries independently.
Let alone the chief surgeon, in large tertiary hospitals, there are not many opportunities for interns to work as serious assistants.
The hospital's surgical classification management is very strict. Even a genius like Yang Ping has to go through the process to obtain surgical permissions before he can have high-level surgical permissions.
For example, ask a qualified doctor to vouch for it. This was the case in Yang Ping in the past. Yang Ping would perform the surgery, and the name of the surgeon would be Director Han. Director Han would sign and confirm. If anything went wrong during the operation, Director Han would be fully responsible.
Another example is that now, the process of hiring from a low-level job to a high-level position is adopted, and a high-level professional title is obtained through shortcuts, and then the highest surgical authority corresponding to the professional title is authorized.
The so-called intern performing surgery is just a fantasy in Cui Xubing's mind.
And those relatives and friends who claimed to know the inside story made serious suggestions to deepen this fantasy in their hearts.

Cui Shukai's scoliosis is a large C shape, reaching 176 degrees.
This kind of severe scoliosis is only six years old and is in the growth and development stage. Once it is not handled well, it will be very troublesome.
Using the newly created spinal external fixator technology, many problems can be solved.
Yang Ping was sitting in his office, facing the computer screen. Cui Shukai's spine CT three-dimensional reconstruction image was suspended on the computer screen. He was planning some details of the operation.
Traditional surgery can only select a few key osteotomy points, use osteotomy to reorganize the spine, and then the vertebrae heal at the osteotomy site.
Just like a curved and inelastic stick, it is cut into several segments, and a wedge-shaped osteotomy is used at the connection to remove the excess part on the convex side. In this way, after reorganization, the deformity is partially corrected.
With Yang Ping's new method, every vertebra involved in the deformity is an osteotomy point.
It does not require the removal of excess bone on the convex side, nor does it require complete amputation of the vertebrae to allow for rehealing.
In this method, the concave side of each vertebra is incised. It is just an incision without removing the bone. Then, an external spinal fixator is installed, and the Ilizarov principle is used to perform distraction osteogenesis at the osteotomy site.
The selection of the vertebral osteotomy site should allow distraction osteogenesis while minimizing damage to the epiphysis.
This curved stick does not need to be broken or reorganized. It can be imagined that it has plasticity and can be slowly straightened. Under the control of the external fixator, the concave side is slowly lengthened. Naturally, the spine is slowly straightened. The whole process is
Dynamic.
Ilizarov's theory is widely used in limb orthopedics, allowing some limb deformities that traditional surgery can't do to achieve very satisfactory results. Now Yang Ping has finally successfully applied this theory to the field of spinal orthopedics.
If you rely on the experience of the surgeon to find the insertion point and direction of the osteotomy line and pedicle screw, you need extensive experience.
By handing over this task to computers and surgical robots, key steps in surgery become foolproof.
Through computer simulation and calculation, the precise position of the osteotomy line, as well as the needle insertion point and direction of the pedicle screw are determined, and then these data are packaged and put into the surgical robot host.
During surgery, the surgical robot can accurately position according to the real-time fluoroscopic images, making it safe, fast, precise, and minimally invasive.
Huang Jiacai personally delivered the instruments. He used a cart to deliver two large boxes of instruments to Yang Ping's office for Yang Ping to conduct preoperative examinations.
Two equipment boxes were opened on Yang Ping's desk.
One set is a percutaneous pedicle screw system. These pedicle screws will be drilled percutaneously into the pedicles of the vertebrae and into the vertebral body.
Each screw is partially exposed outside the skin and becomes a connection point for the external fixator.
The other is a box for spinal external fixators. These external fixators are a large frame, and then matched with many small frames.
The large frame and the small frame perform bone transportation together, and bone transportation is distraction osteogenesis.
When the large frame turns the control knob, all osteotomy sites will start to be transported at the same time, while when the micro frame turns the knob, only one osteotomy site will be transported.
The large and small frames are exquisitely designed and work together to allow the correction of the spine to occur on all vertebrae involved in the deformity.
Cui Shukai will review the X-rays regularly after the operation. He can also make adjustments based on the reviewed X-rays to control the speed of bone transportation, so that the spine can be accurately transported according to the expected route.
Generally, the knob will be turned to start transporting 7-10 days after surgery. According to the transporting speed of 1 mm per day, 3 cm of bone transport can be completed in one month.
This method distributes the correction to all responsible vertebrae, so even the largest bone transfer is only 3 cm.
Including the rest period during the transportation and the solidification period after the transportation is completed, it is estimated that the correction can be completed in about three months.
It takes three months to straighten the C-shaped spine, and the possibility of neurological complications is minimal because it is corrected slowly.
Looking at the exquisite equipment on the desk, Yang Ping himself felt that this was a genius idea.
"Cui Shukai's CT scan data has been sent to Professor He, and we are waiting for his data package. Once the data package is ready, it can be put into the surgical robot host, and the robot can use these data for navigation."
Huang Jiacai is also confident in this set of equipment. This is Ruixing's core product and a powerful weapon to compete with the giants.
"Professor, in order to open the market as soon as possible, I am ready to fully release the patent on this set of equipment and let the whole world use it for free." Huang Jiacai asked tentatively.
Yang Ping was still playing with the equipment: "You decide this matter. I don't understand business matters and I don't want to participate."
"Understood, then I have decided this. In fact, only free patents can allow manufacturers of all sizes to participate. As long as everyone participates, our technology and products can be popularized quickly. As long as our products are popularized, there is nothing we can do about it.
Make money."
This chapter is not over yet, please click on the next page to continue reading! Huang Jiacai said over and over while helping to hand the equipment to Yang Ping.
Although Yang Ping has no interest in these things, he still has to make it clear that for such a major decision, he must explain his reasons.
Yang Ping is his backstage boss, so he must give his boss a clear explanation.
Yang Ping had been assembling the equipment and didn't seem to be listening much.
"Professor, did you - heard - what I just said?"
Huang Jiacai asked.
Yang Ping raised his head: "Listen, please continue, oh, pass me the screw over there."
After saying that, Yang Ping went back to trying to install the external fixator.
"Professor, what I mean is that I want to open the patent for your spinal external fixator to the whole world. Do you have any objection?"
Huang Jiacai had no choice but to say it again.
Yang Ping had no time to care about him: "Ask Professor He to send the data packet as soon as possible."
"professor?"
Huang Jiacai didn't give up before he got a reply.
"You say, you say---" Yang Ping was a little annoyed with him.
"Professor, I will release the patent for the spinal external fixator all over the world, free of charge!" Huang Jiacai said for the third time.
Yang Ping said impatiently: "It's such a trivial matter? Are you asking me? You are the boss, you can just decide for yourself. Do something meaningful and bring me that cup of tea."
Huang Jiacai looked at the teacup on the other side of the desk and immediately picked it up and sent it over.
Boss, I’m talking about a business measured in hundreds of millions, but it’s not as meaningful as your cup of tea?
Huang Jiacai was about to cry but had no tears. Forget it, try not to bother him with these things in the future. He could only stand by the desk and hand over things.
For more than an hour, Mr. Huang was so busy that he was sweating profusely while delivering things.
Yang Ping tried to install and dismantle the external fixator for more than an hour.
After finishing his work, Yang Ping sat on a chair and drank tea. Huang Jiacai helped clean up the mess, pack the equipment into boxes, and then wiped the desk clean before exiting the office.
This set of equipment will open a new chapter in scoliosis treatment. Is it really just a sesame in Professor Yang’s heart?
This is sesame, what is watermelon?
Anyway, Huang Jiacai didn't dare to think about what was in Yang Ping's mind. There was no way, Yang Ping's mind was too open.
