Surgery for anterior cruciate ligament reconstruction started at half past eight o'clock.

In order to make this operation more beautiful, Yang Ping used the spare 6,000 points, took out 2,000 points, and bought another 100 ACL reconstruction surgeries in the system space for special training, pushing this single operation from specialization to perfection.

Director Han is reassured of Yang Ping, and every time he operates, he has achieved both speed and quality, which is impeccable.

However, people are always curious, and the meniscus suture last time was not enjoyable, and this time the anterior cruciate ligament was reconstructed, and Director Han decided to go up and have a look again.

Huang Jiahui didn't come, Zhou Can called a few times, but she didn't answer, Zhou Can put the aseptically packaged consumables on the instrument cart.

didn't see Huang Jiahui, Song Zimo frowned, but Yang Ping didn't say anything, and Song Zimo didn't plan to express his opinion for the time being, and he wanted to talk to this little girl afterwards, if something didn't come, there should be a phone call.

"When is the operation?"

Every time he encounters a new category of surgery, the fat man will habitually ask.

"Half an hour!"

Yang Ping looked at the left knee magnetic resonance and bilateral knee CT scan + three-dimensional reconstruction on the reading lamp, and the intercondylar fossa of the left knee had been seriously deformed, and the intercondylar fossa should be shaped during the operation.

The intercondylar fossa is like an arch-shaped cave, and now this cave has collapsed and needs to be rebuilt and restored. I had to refer to the right side, and the right and left sides are mirror images.

"This intercondylar fossa is so difficult to form!" Song Zimo pointed out the intercondylar fossa on the picture.

"The patient went to the outer hospital and didn't do it for him, because he was afraid that the formation would not be good. The formation is not in place, the impact is formed after reconstruction, and the operation is completely failed; The formation is overformed, the patellofemoral joint loses stability, and new troubles come out. Yang Ping explained to Song Zimo.

Song Zimo took out a folded piece of paper: "You see, this is the left knee intercondylar fossa I drew based on the CT three-dimensional reconstruction of the intercondylar fossa of the right knee, with a one-to-one ratio." ”

Song Zimo unfolded the paper, Yang Ping took it, and it was indeed a good drawing.

If you do a rough molding, many doctors will, but to draw a specific and accurate map of the left side based on the right side, this kind of spatial imagination ability is absolutely rare, very rare.

This kind of spatial imagination ability, not everyone has, this requires talent, and it is not an exaggeration to say that one out of 100,000 miles.

Song Zimo played Go blind chess, and throughout the morning, he would not miss a chess piece or make a mistake, what kind of ability is this? Memory and spatial imagination that are difficult for ordinary people to achieve.

Ordinary people's thinking is language, and genius thinking is composed of a large number of pictures, Song Zimo is a real genius, verified it!

"Bring a pen!" Yang Ping improvised to guide Song Zimo.

Song Zimo asked Zhou Can for a blue-black gel pen, Yang Ping called up the three-dimensional map constructed in advance in the brain, this time it was much easier than the last time, the effective preservation time of the graphics in the brain was longer, but there were still some slightly blurred places, Yang Ping immediately made up for the blur according to the CT picture in front of him, it was not so laborious, although it was still difficult, but at least it would not sweat.

Yang Ping sketched a new drawing under his drawings: "When CT is reconstructed in 3D, due to the interference of artifacts, some graphics will be deformed, and we need to correct them. You see, it shouldn't stand out here, it should be smooth; Here, it should go a little deeper; There is also this arc to be corrected slightly. ”

Song Zimo could only smile bitterly, he could only make a mirror composition based on the CT 3D reconstruction image, and could not use the original cross-sectional drawing to reconstruct on the drawing.

But Yang Ping can, Mr. Ning of Huaqiao Building, has not done 3D reconstruction at that time, just CT non-scan, Yang Ping only relied on non-scan pictures, hand-drawn 3D reconstruction on the drawings, what a terrifying brain power is required, this is not something that can be achieved by manpower.

But Yang Ping did exactly it, and Song Zimo saw him do it with his own eyes.

If Song Zimo knew that Yang Ping in front of him didn't need drawings at all, he could compose the drawings in his brain, and he would probably grab Yang Ping to take a CT and MRI of his head to see if there was anything similar to a chip in it.

"You're discussing the formation of the intercondylar fossa?" Director Han put the phone on the shelf next to it and walked over.

Although Director Han completely let go, he still knows the condition of the patient in Corey well, which is a kind of responsibility.

He came over to look at the drawings, and these two boys actually used the intercondylar fossa on the healthy side to draw the correct intercondylar fossa on the affected side, and one of them even processed the artifacts of the reconstructed image.

Huang Jiahui didn't sleep well all night, she kept having a fever, and she was in a blur, she reached out to touch the mobile phone on the bedside, and barely opened her eyes: "It's eight forty!" It's 8:40! ”

The operation started at half past eight, and I should have arrived in the operating room in advance, and now I should be in the operating room, standing next to the instrument cart.

It was as if she had been splashed from the top of her head by a basin of ice water, and she suddenly woke up, her muscles ached all over her body, and her lower abdomen was even more colic.

My brother had something to do last night and didn't come back, otherwise he would have woken her up.

Jiahui almost cried, got up immediately, dragged her heavy body, and rushed to wash, no, make a phone call first.

The operation has already begun, whose phone call is it, call Song Zimo, it seems that Dr. Yang is handing over these things to him.

---

On the shelf, Song Zimo's mobile phone vibrate.

Zhou Can picked up the phone: "Song Zimo, Huang Jiahui's phone?" ”

"You take it!" Song Zimo is busy.

Zhou Can connected the phone, and after hearing it clearly, he relayed it to Song Zimo: "Huang Jiahui said I'm sorry, she had a high cold and fever last night, and now she still has a high fever, and she is late, so she will come over immediately." ”

"Don't let her come!" After Yang Ping explored the knee joint, confirmed the rupture of the anterior cruciate ligament, and began to prepare to take the tendon, semitendinosus and gracilis muscles on the same side.

"Little girl, it's too hard, I have to rush over with a high fever, and I don't need her to come for surgery in the future." Yang Ping said as he did it.

Zhou Can took Yang Ping's meaning and said into the phone: "Doctor Yang said that you don't have to come over in the future." ”

The level of this communication, Chinese is absolutely failing, "don't come in the future", and "don't come", is the same meaning?

---

What is called not having to come over in the future, be direct, get out! You don't want to do this piece of business anymore!

Without any advance greeting, absent from the operation, this is a serious mistake, I have a colleague like this, angering a big professor, the professor said so - you don't use it in the future, the company directly fired the colleague in order to appease the professor.

Jiahui didn't even have the heart to wash his face and brush his teeth, tears flowed out, this time he was in trouble, poked out the big basket, he immediately called his brother's phone to ask for help, but there was a busy sound.

There was no way, she was stubborn, quickly washed and changed her clothes.

Ignoring the pain in her body and lower abdomen, she rushed out with an environmental bag, and with a gust of wind outside, she shivered, and involuntarily crossed her hands and hugged herself.

The action was a bit exaggerated, and he made a transverse incision of only one centimeter on the inner side of the knee, Song Zimo didn't see it clearly at all, only saw the vascular forceps, sharp knives, and tendon strippers, and operated them in the small incisions one after another.

The two tendons, one by one, were taken out by Yang Ping, and the length of the removal reached the limit, and the tendons of the semitendinosus and the gracilis muscles were both more than 30 centimeters.

"Deal with braided tendons!" Yang Ping handed over the two tendons to Song Zimo, and Song Zimo sat down on the sterile instrument table to deal with the tendons.

At the same time, Xiao Wu supported his legs, and Yang Ping continued to deal with the knee joint.

The lens is reinserted, the meniscus is trimmed as necessary, and the intercondylar fossa begins to form.

The grinding drill rotates at high speed, like a carving knife, and the patient's severely deformed intercondylar fossa is like a blank, and slowly, a perfect normal intercondylar fossa is carved out by the grinding drill.

Then, a plasma knife is used to perform radiofrequency ablation on the inner wall of the formed intercondylar fossa to achieve hemostasis and deactivation, and prevent the intercondylar fossa from continuing to proliferate osteophytes in the future, causing re-stenosis.

"Tibial locator!"

Before Yang Ping could speak, the instrument was already in his hand, and he and Su Yixuan looked at each other for a moment before continuing the operation.

The adjusted tibial positioner is inserted, and the electric drill passes through the tibial platform with a guide needle to drill a tunnel; Release the electric drill, hand it to Su Yixuan, install the second guide pin, and drill out of the second tunnel.

"Is the tendon well handled, report the size!" Yang Ping is waiting.

"Professor Yang! 8 strands of double beam reconstruction too! Can it not be so fast? Song Zimo said this, and he did not show weakness in his hands, as Yang Ping's assistant, who else could I be!

"The length is 8 cm, the diameter is 7 mm at the tibial end, and the femoral end is 8 mm, the two bundles are the same!" Song Zimo can keep up with the rhythm.

"7mm tibia tunnel bit!"

With a rustling sound, the electric drill accurately opened two shin tunnels.

"8mm femoral tunnel bit!"

Yang Ping withdrew from the electric drill, Su Yixuan took it, and immediately replaced it with an 8 mm femur drill bit.

Without intending to stop for a moment, two femoral tunnels were opened, and the rough tunnels were prefabricated with a length of 25 mm.

"Measure the length of the femoral tunnel!"

The ruler was handed over, and it was all put in advance.

"Two tendons, anterolateral bundle with a thick tunnel of 25 mm at the end of the femur and a thin tunnel of 25 mm; Posteromedial bundle, 25 mm thick tunnel at the end of the femur, 20 mm thin tunnel, prepare tendons, hurry! ”

Song Zimo opened his hand speed to the top grid, held his breath, and adjusted the suspension length of the button steel plate just a few seconds after Yang Ping's words fell.

The most critical step in this surgery is the formation of the intercondylar fossa and the precise double-bundled tendon tunnel, once the tunnel is opened incorrectly, or the position is inaccurate, the surgery will fail, and some will cause impaired mobility.

But Yang Ping drove it in a few minutes, and the next steps were even faster, pulling the tendon into the femoral tunnel, waiting for the button steel plate to pull out of the femoral cortex, and then pulling it back and flipping the steel plate. The tendon is then introduced into the tibial tunnel, and the tibial end is secured with absorbable squeezing screws, as is the case with both tendons.

In this way, the ends of the two tendons are planted in the bone tissue, and they are later allowed to survive and play the role of the original ligaments.

The whole operation is equivalent to making a new ligament to replace the ruptured ligament, simulating the work of the original ligament.

"Finished?"

It's okay not to look at it, every time you look at it, you shake your eyes.

Director Han had just studied the CT film for a while, turned around and sat down, ready to take a good look at Yang Ping's operation, and the operation was completed.

Huang Jiahui ran in at this time and saw that everyone was bandaging, ready to open the sterile sheet.

It's over, it's all over!

Jiahui's heart was cold.
