Chapter 553 Remote Control Toy
Brand-new cases and unique surgical plans test the doctor's ability.
Otherwise, how could it be listed as an "Institute of Surgery"? With such a high-quality brand name, it is naturally not something that ordinary departments can compare with.
In order to make the osteotomy more precise, Yang Ping still plans to use the Tianji surgical robot. Good tools are the guarantee of surgical results.
But at present, the robots at the Institute of Surgery have not yet been put in place, and the approval process always takes time.
Yang Ping had no choice but to squeeze in with the Department of Orthopedics. Of course, Director Tan and several other wards of the Department of Orthopedics were very happy.
Borrowing it once will give you an opportunity to observe and learn, so why not do it.
Yang Ping's state of operating surgical robots is a perfect integration of man and machine.
If the level of surgical robots is divided into different levels, 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 been established for a short time, it is actually not short of money at all. Excluding Ruixing Company, it will not be said that it is short of surgical robots.
There are a few big guys who will never be stingy with money. They will donate a robot or something, worth 20 to 30 million yuan, and it’s just a matter of signing their name.
For example, Ning Qi, the CEO of Anning Group, hopes that Yang Ping can make a list. The wording is very particular. It is not a robot, but a list. What equipment is needed? Just write it down 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 to purchase was already on its way, so Yang Ping decided to be more patient and there was no harm in waiting.
Yasmine was wearing a patient uniform from Sanbo Hospital, sitting in a wheelchair and being pushed into the operating room by the nurse.
Dr. Feida also followed Yang Ping into the operating room to visit. He searched everywhere with curious eyes. Thirty operating rooms were under construction at the same time, and about two hundred operations were performed a day. This huge scale was something Dr. Feida would never forget.
What is the concept of concentrating half of the country's surgeries on one floor?
"Is this the largest hospital in China?" Dr. Feida couldn't help but ask.
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 300,000, and the daily operation volume is approaching 1,000."
One thousand units per day! Three hundred thousand units per year!
Dr. Feida clucked his tongue. He had no clear feeling about what a great country is before. Now, as a doctor, he fully felt the momentum of a great power in the operating room.
I used to have very little knowledge and spent most of my time learning English. I once went to a hospital in the UK for further training. That hospital only had 100 beds. During the short training period of two weeks, I only saw a few operations.
You must learn Chinese well, and you must come to China to further your studies.
Dr. Feda swore secretly in his heart.
This time it was Tan Boyun who gave up the robot. Director Qin of the Spine Surgery Department was very angry and snatched the opportunity to give up the robot twice in a row. He felt that Tan Boyun was a bit aggressive, but he had no choice. He was one step late both times.
Light music played in the operating room, the guzheng version of "Mountains and Flowing Water", which sounded very pleasant and comfortable.
When Yang Ping was undergoing surgery, he liked to listen to this soothing guzheng. The piano was actually very good, but he just felt that guzheng had more charm.
Huang Jiahui still followed the stage in person, and all the instruments were spread out beside her. They were a dazzling array of devices, each of which was tailor-made for this operation.
Ruixing's chief engineer Chen Zhi also followed Huang Jiahui to the surgery site. He saw the surgery process with his own eyes. Only if he understands the surgery process can he design better instruments in the future.
Dr. Feda was dazzled by what he saw. He had never seen such a scene when he was studying in England.
Besides, the British professor's aura was still far behind Professor Yang's. Dr. Feida couldn't tell how much.
Tan Boyun applied to be an assistant on stage, but was rejected by Yang Ping.
Using your robot does not necessarily allow you to take the stage. In fact, this is not a strange thing.
For any operation, Yang Ping will make some calculations in his mind to strive for the greatest success rate and the best effect.
Tan Boyun was far less prepared for the operation than Song Zimo and Xu Zhiliang. If he agreed to Tan Boyun as an assistant, it would increase unnecessary risks for the operation.
Director Tan knew Yang Ping very well and was merciless during the operation.
So he doesn't feel sad at all. The days are long and there will be many opportunities in the future. Standing by and watching, you can learn a lot.
The Arabic translator, also wearing visiting clothes, a sterile cap and a mask, stood nearby 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 Fatty meant, giving her general anesthesia and then sleeping.
It's just that when the fat man imitated the movements of sleeping, the purring sound he made deliberately was a bit ungentle.
On the surface, this surgery is nothing more than artificial joint replacement of four major joints - bilateral hip joints and bilateral knee joints. However, this surgery is very different from ordinary artificial joint replacement.
Yasmine's bilateral hip joints were permanently fixed in a dislocated state due to severe dysplasia.
The original shallow acetabulum was useless for this operation, both in terms of position and depth.
Yang Ping needed to re-ground an artificial acetabulum on his hip bone and then put in a biotype acetabular prosthesis.
There is no standard to follow for the position and direction of this artificial acetabulum, and it is completely customized according to Yasmine.
This requires a comprehensive consideration of the orthopedic hip joints, knee joints, ankle joints, foot arches, and the muscle status around the hip joints.
If you rely solely on experience at this time, no matter how rich your experience is, you will not be able to create an excellent acetabulum.
Computer simulation can easily find the position and direction of the bilateral acetabulum based on the target force line, and it is very accurate.
Similarly, due to the reverse anatomy of the knee joint, the operation is more complicated to restore the forward anatomy and function, and each osteotomy is required to be very precise. The ankle joint and the arch of the foot also need to be modified to accommodate upright walking in the future.
Disinfection and draping, pre-operative verification, and official opening.
Song Zimo and Xu Zhiliang were on the stage, and Yang Ping was operating the surgical robot in front of the control platform.
Yang Ping chose the order from proximal to distal, first performing bilateral hip replacements, and finally dealing with the ankle joints and arches of the feet.
Only when the hip joint has good range of motion can knee replacement achieve a good surgical angle.
Dr. Feida stood nearby and carefully watched the operation video on the screen. He now regarded himself as a training doctor.
Yang Ping used the lateral approach to the hip joint, incised layer by layer to expose 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 walking upright.
The stable structure of human joints is divided into two parts. One part is the dynamic stabilizing structure: the muscle tendon system; the other part is the static stabilizing structure: the joint capsule and ligaments.
Their relative balance allows the joints to remain stable while still gaining a certain degree of flexibility.
Therefore, this surgery requires very high balancing skills.
After the soft tissue was released, Yang Ping used the precise positioning of the robot to grind an artificial acetabulum on the hip bone, and then inserted the bioartificial 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 polymethylmethacrylate, which is suitable for older patients with poor bone quality. In this type of patients, bone cement is used to fix the prosthesis and bone during hip joint replacement.
Just like when building, cement is used to fix bricks and other building materials, hence the name.
Biotype is different from bone cement in that it is suitable for young patients with good bone quality.
This kind of artificial joint prosthesis does not need to add a fixative such as bone cement. For example, the stem of the femoral head prosthesis is inserted into the proximal medullary cavity of the femur, and the stem and the medullary cavity are squeezed to obtain initial stability, 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 be fixed between the bricks. The bricks will grow and penetrate each other, and finally be firmly connected.
Song Zimo and Xu Zhiliang cooperated very well and switched equipment very quickly.
A robotic arm of the Tianji surgical robot is very flexible, whether it is drilling the acetabulum or osteotomy of the proximal femur, it is fast and precise.
Soon, Yang Ping completed bilateral artificial hip replacements.
Then began bilateral knee replacement.
After the hip joint is replaced, good range of motion is obtained, and the lower limbs can be placed much freely, which provides a good operating angle for knee joint replacement.
With the help of robotic navigation equipment, osteotomy and prosthesis placement can be completed in one go.
Knee prostheses are also bio-type. There is currently no such bio-type knee prosthesis on the market. The prosthesis used by Yang Ping was completely printed with a 3D printer.
Like hip joint prostheses, this new type of prosthesis is in close contact with traditional bone cement prostheses through the prosthesis-bone interface, which promotes bone tissue to grow into the prosthesis and improves the bonding strength between the prosthesis and the medullary cavity, thus Achieve long-term stability of the prosthesis.
West China Hospital once completed the world's first biological knee prosthesis replacement surgery. The artificial joint prosthesis at that time was also printed with a 3D printer. I don't know if Yang Ping's one is the second in the world.
The surgical robot is really like playing a game in Yang Ping's hands, and the bilateral knee joint replacement is 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 control platform and came to the operating table. Song Zimo began to measure the force lines of the lower limbs - perfect!
The whole surgery didn't feel like surgery, but like a video game.
From start to finish, every step was fast and precise, and bleeding was minimal and almost negligible.
The Tianji robot's single arm is completely insufficient and cannot keep up with Yang Ping's speed, and many steps require manual assistance.
The improved robot in the future should be like this. The surgeon controls the robot to complete all steps, and switching instruments should also be done automatically. The instruments should be 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 emergencies if the machine goes out of control and should not be involved in the operation.
Therefore, Tianji Robot still has a lot of room for improvement.
At present, surgical robots cannot keep up with Yang Ping's speed, and many functions cannot be realized, requiring help from people to load and unload instruments.
"Chen Zhi, surgical robots represent the future direction of surgery. You should make a difference."
Yang Ping told engineer Chen Zhi.
This statement coincides with Chen Zhi's idea. He has 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 just a piece of cake. If he had sufficient funds, Chen Zhi would really like to design such a large piece.
However, this requires massive funds and a large 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 draping, disinfection, incision, etc.
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 that surgical robots must be networked with supercomputers and be able to combine with digital humans for real-time modeling during surgery to provide assistance during surgery.
