A new case, a unique surgical plan, this is the test of the doctor's ability.

Otherwise, how can the "Surgical Research Institute" be listed, such a high signboard is naturally not comparable to ordinary departments.

In order to make the osteotomy more accurate, Yang Ping still plans to use the Dimensity surgical robot, and good tools are the guarantee of the surgical effect.

However, at present, the robots of the Institute of Surgery have not been put in place for a long time, and the approval process always takes time.

Yang Ping had no choice but to squeeze with the big orthopedic department, of course, whether it was Director Tan or several other wards in the orthopedic department, they were very happy.

Borrow it once, and you will get a chance to observe and learn, so why not.

Yang Ping's realm of operating surgical robots is a proper integration of man and machine.

If the level of the surgical robot is segmented, Yang Ping should be the strongest king, and the one with the most stars.

Experiencing Yang Ping's robotic surgery up close, you can get a sense of operation like playing a game, which is very enjoyable.

Although the Institute of Surgery has not been listed for a long time, it is actually not short of money at all, and Ruixing Company is excluded, and it will not be said that there is a shortage of surgical robots.

There are a few bigwigs who will never be stingy with money, donating a robot or something, twenty or thirty million things, and signing their names.

For example, Ning Qi, the boss of Anning Group, hopes that Yang Ping can make a list, people's words are very particular, not a robot, or a list, what equipment is needed, although write on it, she will provide, and the procedure is donation.

As long as Yang Ping is willing, it is not difficult for her to donate a building and a hospital.

The robot that Dean Xia applied to buy was already halfway there, and Yang Ping decided to be more patient and wait.

Yasmeni was dressed in a patient gown from Sanbo Hospital, sitting in a wheelchair and being pushed into the operating room by a nurse.

Dr. Feida also followed Yang Ping into the operating room to visit, his curious eyes searched everywhere, thirty operating rooms were started at the same time, about 200 surgeries a day, this grand scale, Dr. Feida unforgettable for life.

What is the concept of concentrating half of the surgery in their country on one floor?

"Is this the largest hospital in China?" Dr. Feda couldn't help but ask.

With the help of the Arabic translator, Xiao Wu told him: "We are not the biggest, the largest hospital in China has an annual capacity of about 300,000 surgeries, and the daily volume of surgeries is approaching 1,000." ”

1,000 units per day! 300,000 units per Chinese New Year's Eve!

Dr. Feida was speechless, what is a big country, he didn't have a clear feeling before, At this moment, as a doctor, he fully felt the momentum of a big country in the operating room.

I used to be really shallow, I spent most of my time learning English, and I once went to a hospital in the United Kingdom for further study, which only had 100 beds, and I only saw a few surgeries for two weeks of short-term training.

You must learn Chinese well, and you must come to China for further study.

Dr. Feida swore in his heart.

This time it was Tan Boyun who gave up the robot, Director Qin of the Spine Surgery Department was very annoyed, and grabbed the opportunity to let the robot out twice in a row, he felt that Tan Boyun was a little aggressive, but there was no way, he was one step behind both times.

Light music sounded in the operating room, and the guzheng version of "Mountains and Flowing Water" sounded very pleasant and comfortable.

When Yang Ping had surgery, he liked to listen to this soothing guzheng, and the piano was actually very good, but he just felt that the guzheng was more charming.

Huang Jiahui still followed the stage in person, and all the instruments were unfolded next to her, dazzling and varied, and each instrument was tailored for this operation.

Chen Zhi, the chief engineer of Ruixing, also followed Huang Jiahui to the operation site, he saw the process of surgery with his own eyes, only if he understood the process of surgery, can he design better instruments in the future.

Dr. Feda was dazzled by the sight of such a scene when he was studying in England.

Besides, there is still a gap between the British professor's aura and Professor Yang's, and how much worse it is, for the time being, Dr. Feida does not know in his heart.

Tan Boyun applied to be an assistant on stage, but was rejected by Yang Ping.

Using your robot doesn't necessarily have to put you on stage, but it's not a strange thing.

Any operation, in Yang Ping's heart, will be calculated, for the greatest success rate, the best results.

Tan Boyun's preparation for this operation is far less adequate than that of Song Zimo and Xu Zhiliang, and if Tan Boyun is agreed to be an assistant, it will add unnecessary risks to the operation.

Director Tan understands Yang Ping very well, and when he does surgery, he shows no mercy.

So he didn't feel sad, the future is long, and there will be many opportunities in the future, and he can learn a lot by standing by and watching.

The Arabic translator lady, also wearing a gown, a sterile cap and a mask, stands next to her to provide translation services at any time.

Body language is the most common language in the world.

Liang Fatman's gesture was very good, and Yasmeni understood what the fat man meant, and wanted to give her general anesthesia and then sleep.

It's just that when the fat man imitates the action of sleeping, the deliberate snoring sound is a little unelegant.

On the surface, this surgery is nothing more than artificial joint replacement of four large joints - bilateral hip joint joint replacement - bilateral knee joint, but this operation is very different from ordinary artificial joint replacement.

Yasmeni's bilateral hip joints were severely underdeveloped and were immobilized in a dislocated state for a long time.

The original shallow acetabulum, both in position and depth, was useless for this surgery.

Yang Ping needs to regrind an artificial acetabulum on the hip bone and then place a biotype acetabular prosthesis.

There is no standard for the position and orientation of this acetabular implant, which is completely personalized according to Yasmene.

This requires a holistic consideration of the orthopedic hip, knee, ankle, and arch of the foot, as well as the muscles around the hip joint.

At this time, if you only rely on experience, no matter how experienced you are, you can't dig an excellent acetabulum.

Computer simulations can easily find the position and direction of the acetabulum on both sides according to the target line of force, and it is very accurate.

Similarly, because of the reverse anatomy of the knee joint, the operation is more complex to restore the forward anatomy and function, and the requirements for each osteotomy are very precise.

The ankle and arch of the foot also need to be modified to accommodate later upright walking.

Disinfection sheet, preoperative check, official opening.

Song Zimo and Xu Zhiliang were on stage, and Yang Ping operated the surgical robot in front of the platform.

Yang Ping chose the order from near to far, first doing bilateral hip replacement, and finally dealing with the ankle joint and arch.

Only when the hip joint has good range of motion can the knee replacement obtain a good surgical angle.

Dr. Feida stood next to him, the video of the operation on the screen, and he now regarded himself as a trainee doctor.

Yang Ping uses the lateral approach of the hip joint, which is incised layer by layer to expose the hip joint, and the surrounding muscles, tendons and ligaments are moderately loosened to achieve an ideal balance.

This balance is a new balance, a balance that aims to adapt to upright walking.

The stabilizing structure of human joints is divided into two parts, one is the dynamic stabilizing structure: the muscular tendon system; The other part is the statically stable structure: the joint capsule and ligaments.

Their relative balance allows the joints to always be stable and at the same time gain a certain degree of flexibility.

So in this operation, the balance requires a very high level of skill.

After the soft tissue was released, Yang Ping assisted in the precise positioning of the robot, used the acetabulum to grind an artificial acetabulum on the hip bone, and then placed a biological artificial acetabulum.

There are generally two types of hip prosthesis fixation, bone cement type and biological type.

The main component of bone cement is polymethyl methacrylate, which is suitable for patients with age and poor bone quality.

Just like when building, cement is used to fix building materials such as bricks, hence the name.

The biotype is different from bone cement in that it is suitable for young, well-boned patients.

For example, the stem of the femoral head prosthesis is inserted into the medullary cavity at the proximal end of the femur, and the shank and the medullary cavity are squeezed to obtain initial stability, because the surface of the stem of this prosthesis is porous, and there is a coating that induces bone growth, so slowly, the bone tissue of the medullary cavity will grow into the gap of the stalk, forming a so-called biological fixation.

Just like building a house, there is no need for cement to fix between the bricks and the bricks, these bricks will grow and penetrate each other, and finally connect firmly.

Song Zimo and Xu Zhiliang cooperated very well, and the speed of switching instruments was also very fast.

One of the robotic arms of the Dimensity surgical robot is very flexible, whether it is the excavation of the acetabulum or the osteotomy of the proximal femur, it is fast and accurate.

Soon, Yang Ping completed bilateral artificial hip replacement.

Bilateral knee replacement is then initiated.

After the hip joint is replaced, a good range of motion is obtained, and the lower limbs are placed much more freely, which provides a good operating angle for knee replacement.

With the help of robotic navigation equipment, the osteotomy and implant placement are completed in one go.

The knee prosthesis is also biotype, there is no such biological knee prosthesis on the market, and the prosthesis used by Yang Ping is completely printed with a 3D printer.

Like hip prostheses, this new type of prosthesis is in close contact with the prosthesis-bone interface through close contact between the prosthesis and the bone interface, which promotes the growth of bone tissue into the prosthesis and improves the bonding strength between the prosthesis and the medullary cavity, so as to achieve long-term stability of the prosthesis.

West China Hospital once completed the world's first biological knee joint prosthesis replacement surgery, and the artificial joint prosthesis at that time was also printed with a 3D printer.

The surgical robot is really like a game in Yang Ping's hands, and bilateral knee replacement is completed.

Finally, the ankle and arch of the foot are treated, and in order to accommodate upright walking, the ankle and arch must be orthopedic at the same time.

After all the steps were completed, Yang Ping left the control platform and came to the operating table, and Song Zimo began to measure the line of force of the lower limbs - perfect!

The whole operation is less like an operation, more like a video game.

From start to finish, every step is fast and precise, with minimal bleeding and almost negligible.

The one-arm of the Tianji robot is completely insufficient, and it can't catch up with Yang Ping's speed at all, and many steps need to be assisted manually.

In the future, the improved robot should be like this, the main knife controls the robot to complete all the steps, and the switching of instruments should also be done automatically, the instruments are placed on the instrument table, and the robotic arm should be able to automatically load and unload the instruments.

The assistant is only there to deal with the unexpected situation of the machine getting out of control, and should not be involved in the operation.

Therefore, there is still a lot of room for progress in Tianji robots.

Now it is completely impossible for surgical robots to catch up with Yang Ping's speed, and many functions cannot be realized, and it is necessary to rely on people to help load and unload instruments.

"Chen Zhi, surgical robots represent the future direction of surgery, and you should make a difference."

Yang Ping said to engineer Chen Zhi.

This is exactly in line with Chen Zhi's idea, he has always had this idea, to develop surgical robots, so this time I came to see the operation of surgical robots in person.

Designing those instruments is just a small fight, and if the funds are sufficient, Chen Zhi would like to design such a large piece.

However, this requires a lot of money and a large team.

The robot must have more than three robotic arms, the robotic arm must be a combination of flexibility and rigidity, the robotic arm must be able to completely replace the human hand, and the robotic arm must be able to complete the entire surgical process such as laying a single small shop and incision.

Otherwise, it is not a qualified remote control toy.

Chen Zhi thought that he must design such a qualified remote control toy.

Finally, he thought, surgical robots must be networked with supercomputers that can be combined with digital humans for real-time modeling during surgery.

The first is the latest.
