godfather of surgery

Chapter 553 Remote Control Toys
A brand new case and a unique surgical plan test the doctor's ability.

Otherwise, how would they list the "Surgery Research Institute"? Such a high-quality signboard is naturally not comparable to ordinary departments.

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

But at present, the robot of the Institute of Surgery has not been in place for a long time, and the approval process always takes time.

Yang Ping had no choice but to squeeze with the Department of Orthopedics. Of course, whether it was Director Tan or the other wards of the Department of Orthopedics, they were very happy.

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

Yang Ping's realm of operating surgical robots is a perfect combination of man and machine.

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

Experience Yang Ping's robotic surgery at close range, and you can get a visual sense of the 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. Excluding Ruixing Company, 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, donate a robot or something, two or 3000 million things, just sign their names.

For example, Ning Qi, the boss of Anning Group, hopes that Yang Ping can make a list. His words are very particular. It is not a robot, but a list of what equipment is needed. Just write it on it, and she will provide it. The procedure is: donate.

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

The robot that Dean Xia applied for to purchase is already on the way, Yang Ping decided to be more patient, it doesn't hurt to wait.

Wearing the patient gown of Sanbo Hospital, Yasminie sat in a wheelchair and was pushed into the operating room by the nurse.

Dr. Fei Da also followed Yang Ping into the operating room to visit. His curious eyes searched everywhere. Thirty operating rooms were open at the same time, and about [-] operations were performed a day. Such a grand scale made Dr. Fei Da unforgettable for a lifetime.

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

"Is this the largest hospital in China?" Dr. Fei Da couldn't help asking.

With the help of the Arabic translator, Xiao Wu told him: "We are not the largest. The largest hospital in China has an annual operation volume of about 30, and the daily operation volume has approached [-]."

One thousand units per day!30 units per year!
Dr. Fei Da was speechless. He didn't have a clear feeling about what a big country is before. Now, as a doctor, he can fully feel the aura of a big country in the operating room.

In the past, I was really short-sighted. I spent most of my time learning English. I once went to a hospital in England for further study. That hospital only had [-] beds. I only saw a few operations during my short-term study for two weeks.

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

Doctor Fei Da swore inwardly.

This time it was Tan Boyun who gave up the robot. Director Qin of the spinal surgery department was very annoyed and took the opportunity to give up the robot twice in a row. He felt that Tan Boyun was a bit aggressive, but there was nothing he could do. He was one step late both times.

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

When Yang Ping was undergoing surgery, he liked to listen to this kind of soothing guzheng. The piano is actually very good, but he just thinks the guzheng has more charm.

Huang Jiahui still followed the stage in person, and all the instruments were unfolded beside her. There was a wide variety of beautiful things in eyes, and each instrument was tailor-made for this operation.

Ruixing's chief engineer, Chen Zhi, also followed Huang Jiahui to the operation site. He saw the operation process with his own eyes. Only he understood the operation process, so he could design better instruments in the future.

Dr. Fei Da was dazzled. He had never seen such a scene when he was studying in England.

Besides, there is still a gap between the aura of the British professor and that of Professor Yang. To what extent, Dr. Fei Da doesn't know for the time being.

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

It's not a surprise that you don't have to be on stage to use your robot.

For any operation, Yang Ping will calculate it in his mind, striving for the greatest success rate and the best effect.

Tan Boyun was far less prepared for this operation than Song Zimo and Xu Zhiliang. If Tan Boyun was allowed to be an assistant, unnecessary risks would be added to the operation.

Director Tan knows Yang Ping very well, and he is merciless when performing surgery.

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

The Arabic translation lady, also wearing a visitor's gown, a sterile cap and a mask, stood by to provide translation services at any time.

Body language is the most universal language in the world.

Fatty Liang's gestures were very good, and Yasmeni understood what the fatty meant, and wanted to give her general anesthesia and then go to sleep.

It's just that when the fat man imitated the action of sleeping, the purring sound he made on purpose was a bit unrefined.

On the surface, it seems that this operation is nothing more than artificial joint replacement of four major joints --- bilateral hip joints and bilateral knee joints, but this operation is very different from ordinary artificial joint replacements.

Due to severe dysplasia, Yasmeni's bilateral hip joints have been fixed in a dislocated state for a long time.

The position and depth of the original shallow acetabulum was useless for this operation.

Yang Ping needed to re-grind an artificial acetabulum on the hip bone, and then put in a biological acetabular prosthesis.

There is no standard to follow for the position and direction of the artificial acetabulum, and it is completely customized according to Yasmeni.

This requires overall consideration of the hip joint, knee joint, ankle joint, arch of the foot, and the state of the muscles around the hip joint after correction.

At this time, if only relying on experience, no matter how rich the experience is, it will not be possible to excavate an excellent acetabulum.

The computer simulation can easily find out the position and direction of the bilateral acetabulum according to the target line of force, and it is very accurate.

Similarly, due to the reverse anatomy of the knee joint, it is more complicated to restore the positive anatomy and function, and the requirement for each osteotomy is very precise.

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

Disinfect the sheets, check before the operation, and officially open.

Song Zimo and Xu Zhiliang are on stage, and Yang Ping is operating the surgical robot before manipulating the platform.

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

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

Dr. Fei Da stood beside him, carefully watching the operation video on the screen. He now regarded himself as a doctor in training.

Yang Ping adopted the lateral approach of the hip joint, incision layer by layer, exposed the hip joint, and moderately released the surrounding muscles, tendons and ligaments to achieve an ideal balance.

This balance is a new balance, a balance aimed at adapting to upright walking.

The stable structure of human joints is divided into two parts, one is dynamic stable structure: muscle tendon system; the other is static stable structure: joint capsule and ligament.

Their relative balance can make the joints always stable and at the same time obtain a certain degree of flexibility.

Therefore, this surgery requires a very high level of skill in balance.

After the soft tissue was loosened, Yang Ping used the precise positioning of the robot to grind out an artificial acetabulum on the hip bone with the acetabulum, and then placed it into a biological artificial acetabulum.

There are generally two types of fixation methods for hip prostheses, bone cement type and biological type.

The main component of bone cement is polymethyl methacrylate, which is suitable for elderly patients with poor bone quality. When these patients undergo hip replacement, bone cement is used to fix the prosthesis and bone.

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

Biotype is different from bone cement, it is suitable for young patients with good bone quality.

This kind of artificial joint prosthesis does not need to add bone cement as a fixative. For example, the stem of the femoral head prosthesis is inserted into the medullary cavity of the proximal femur, and the stem and the medullary cavity are initially stabilized by extrusion, because the stem of this prosthesis The surface is porous and has a coating that induces bone growth, so slowly, the bone tissue in the medullary cavity will grow into the gap of the handle, forming a so-called biological fixation.

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

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

One robotic arm of the Tianji 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 replacements.

Then start the bilateral knee replacement.

After the hip replacement is completed, a good range of motion is obtained, and the placement of the lower limbs is much freer, which provides a good operating angle for the knee replacement.

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

The knee prosthesis is also bio-based. There is no such bio-based knee prosthesis on the market at present. The prosthesis used by Yang Ping is completely printed with a 3D printer.

Like the hip joint prosthesis, this new type of prosthesis, compared with the traditional bone cement prosthesis, promotes the bone tissue to grow into the prosthesis through the close contact between the prosthesis-bone interface and improves the bonding strength between the prosthesis and the medullary cavity, thereby To achieve long-term stability of the prosthesis.

West China Hospital once completed the world's first biological knee prosthesis replacement surgery. At that time, the artificial joint prosthesis was also printed by 3D printers. I don't know if Yang Ping's is the second case in the world.

The surgical robot is really like playing a game in Yang Ping's hands, and both knee joint replacements have been completed.

Finally, the ankle joint and the arch of the foot are dealt with. In order to adapt to upright walking, the ankle joint and the arch of the foot must be corrected at the same time.

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

The whole operation is not like surgery, but like a video game.

From start to finish, every step was quick and precise, with minimal, almost negligible bleeding.

The one arm of the Tianji robot is not enough at all, it can't keep up with Yang Ping's speed, and many steps need manual assistance.

The improved robot in the future should be like this. The chief surgeon manipulates 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 must be able to automatically load and unload the instruments.

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

Therefore, there is still a lot of room for the Tianji robot to improve.

Now the surgical robot is completely unable to keep up with Yang Ping's speed, and many functions cannot be realized, and it is necessary to rely on humans to help load and unload instruments.

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

Yang Ping told engineer Chen Zhi.

These words coincided with Chen Zhi's idea. He had always had this idea to develop a surgical robot, so this time he came to see the operation of the surgical robot in person.

Designing those equipment is nothing more than a small matter. If the funds are sufficient, Chen Zhi would like to design such a large piece.

But this requires a lot of money and a huge team.

The robot must have more than three robotic arms. The robotic arms must be flexible and rigid. The robotic arms must be able to completely replace human hands. The robotic arms must be able to complete the entire surgical process such as laying, disinfection, and incision.

Otherwise, it is not a qualified remote control toy.

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

In the end, he thought, surgical robots must be networked with supercomputers, and can be combined with digital humans for real-time modeling during surgery to provide assistance for surgery.
