It was expected to take three days, but on the second day, Professor He's team completed the construction of the whole lower limb digital model of Fangfa ahead of schedule.
The force lines, osteotomy lines, and fixation pin distribution points of the left lower limb were selected by the computer, and the data calculated using the model were edited into a form that can be implanted into the surgical robot host
Professor He sent his students to use a mobile hard drive to send the data to Yang Ping. With this mobile hard drive, this complex surgery will be simplified.
There is currently no Tianji surgical robot at the Institute of Surgery, so Yang Ping arranged Fang Faquan’s surgery to be performed at the surgery center.
Sanbo Hospital currently has two Tianji surgical robots, one in the Department of Traumatology and Orthopedics, and one shared by other orthopedic departments.
Yang Ping plans to buy one himself, but a machine costs 15 million and needs approval.
Dean Xia has submitted the application for approval to the superiors, and the process is almost complete.
One hospital has three Tianji machines, which is a big customer.
Manager Gu of the South China region of Tianji Surgical Robot heard that Yang Ping was performing the surgery today and came to the operating room early. Tianji Company and Sanbo Hospital planned to establish a training center and asked Yang Ping to come forward as an instructor.
This was all caused by the previous episodes of Leonardo da Vinci’s Dance and the Painting of Tianji. The two videos are still circulating on the Internet.
Especially your Da Vinci dance, it really surpassed the ceiling of surgical robot control.
The four robotic arms are entangled with each other in the small glass bottle, but do not touch each other, creating a lingering and coquettish dance.
Yang Ping came to the surgery center early. Many orthopedic surgeons heard that Yang Ping came to perform surgery, and they all tried their best to find time to observe.
I really want to see the magical operation of the surgical robot in Yang Ping's hands again.
"Hello, Professor Yang!"
"Hello, Professor Yang!"
"Hello, Professor Yang!"
This was the peak time for doctors to enter the operating room. Along the way, the doctors who saw Yang Ping nodded and said hello.
They have seen the notice on the hospital intranet that Yang Ping has been successfully promoted to associate professor.
Such a young and newly promoted attending physician has been promoted to deputy chief physician and associate professor in succession.
Even if you are hired from a low-level position to a high-level job, it is still very impressive.
What a youthful success!
"Professor Yang!" Director Tan and Manager Gu came out to greet him, accompanying Yang Ping on the left and right.
Although Tan Boyun is arrogant and has a bad temper, he is a man who believes in strength.
If you are really capable, he will be convinced.
Originally, Director Tan wanted to come on stage as an assistant, but two generals, Song Zimo and Xu Zhiliang, were about to come on stage, and there was no room for him on the operating table.
In the multifunctional operating room of the Orthopedic Traumatology Department, the "One-Armed Man" Tianji surgical robot stands quietly next to it, with the optical tracking system, the robotic arm host, and the main control trolley, all three parts ready.
These three parts are equivalent to the eyes, hands, and brain of the surgical robot.
Its eyes can see through and its hands are very stable.
The optical tracking system is like a "see-through eye" that sees deep into the muscles and bones and monitors every aspect of the surgery in real time.
The robotic arm is the "stabilizing hand" of the robot. It has flexible movement, stable operation, and can achieve sub-millimeter accuracy. Its end can be connected to various instruments, electric drills, electric saws, screwdrivers, guides, etc. The robot relies on these tools to complete the work.
Surgery.
The main control computer system is equivalent to the brain of the robot, conveying the doctor's ideas to the above two devices, helping the doctor to carry out precise positioning and path planning.
The surgical robot can also track the patient's movement during the operation, and the robotic arm automatically compensates for the position difference to ensure that the surgical positioning path is consistent with the planned positioning path.
Fatty is preparing to give Fangfa full anesthesia. This guy seems to be talking to Xiaowu about something.
"This robot won't lose control, right?" Fang Faquan looked at the robot in the operating room and was quite worried.
Hearing that Yang Ping was going to use a robot to perform surgery on him, he also checked some information on the Internet. He felt a little guilty when he saw a case of a robot running out of control.
"No, don't worry. If it gets out of hand, I'll pull the plug." Xiao Wu pointed at the switch on the wall.
Fang Faquan was still worried: "Does the robot have a battery?"
His understanding is that if there is battery power, it will be useless to pull the plug.
Xiaowu comforted him again: "If you don't bring a battery, the power will be cut off as soon as you pull it out."
Zhang Lin saw that his hair was all quivering and said: "Fat man, give him some medicine and let him sleep."
Fang Faquan was even more frightened now: "Don't let me sleep, doesn't it mean half numb? Only the lower half of the body is numb?"
"Then relax, don't be so nervous. This robot has successfully completed hundreds of operations." The fat man comforted him.
How dare Fang Faquan sleep? If he did, the robot would go berserk and there would be no way for him to escape.
"I'm telling you, you can finish the operation just after you sleep. Don't be so nervous. Moreover, the anesthetic I give you will usually make you have sweet dreams. For example, in your dream, you will have a large group of beauties to choose from as your wife." Zhang Lin advised him.
Just push it and save yourself the hassle.
Fang Fa refused: "I'm a real person and don't like to daydream. I'm not interested in you being the emperor in my dreams."
The guy was shivering, and the heart rate on the screen was over a hundred beats per minute.
The fat man gave him a little sedative, and his heart rate slowly came down.
Yang Ping came over and said to Fang Faquan: "Relax, this kind of robot is called a robot, but it is not a robot. It is a remote-controlled surgical machine, and it is all under my control."
Fang Faquan always thought that this robot had autonomous thinking, and like in the movie, it would kill people if they disagreed.
If it's just a remote control tool, then don't worry, after all, the control is in the hands of the person.
"Professor Yang, what do you mean, this robot is completely in your hands?"
Fang Faquan asked.
Yang Ping nodded: "Yes, I control it, and there are people watching it."
I had already discussed these things with him before the operation, but Fang Faquan was so nervous that he forgot all about them.
Yang Ping did not need to wash his hands and sat in front of the operating table.
Song Zimo took Xu Zhiliang to wash hands and go to the stage to disinfect the sheets. They are assistants. The assistants are responsible for assembling instruments on the stage and assisting the robotic arm in completing the surgery.
Everything is ready and ready to start.
"Condoms, get condoms quickly!"
Zhang Lin yelled at the traveling nurse.
This chapter is not over yet, please click on the next page to continue reading!
"What are you so anxious about?"
The traveling nurse is not a vegetarian either, she directly confronts Zhang Lin.
In fact, the so-called robot is still far away from the robot. At most, it is a remote-controlled surgical machine. One or several remote-controlled mechanical arms replace the doctor's hands to operate the surgery.
Based on the X-ray perspective, the real-time reconstructed images obtained on the screen include the tibia, fibula, calcaneus, talus, etc., which are clear and can be rotated to obtain the best angle.
Several needle placement positions are marked by blue origins, and the direction of needle insertion is a blue straight line.
The robotic arm holds the drill bit with a fixed pin. The fixed pin appears on the screen. The robotic arm automatically aligns with the origin, then adjusts the direction so that the direction of the needle overlaps the indicated straight line. The calibration is completed, and then it is firmly stabilized. p>
The drill bit rotates at high speed, and the fixed needle enters exactly in the specified direction. The needle entry point, direction, and depth are all accurately completed according to the predetermined data.
Each needle is screwed in this fool-like way.
In the second step, the osteotomy begins. Song Zimo cuts the skin at the planned osteotomy location and uses a retractor to retract the osteotomy area to reveal the osteotomy site.
Xu Zhiliang replaced the instrument on the robotic arm with a miniature oscillating saw, and then the saw blade appeared on the screen.
In the left lower limb bone in the picture, the location of the osteotomy has been marked by a blue line. The position, length and direction are accurate to the sub-millimeter level.
The saw blade searches for the direction and starts automatic calibration. After calibration, the robotic arm locks and starts osteotomy according to the fixed route.
Likewise, every osteotomy is done with great precision.
Under Yang Ping's control, the robotic arm moves smoothly and rhythmically.
Director Tan felt that there should be music here, so he asked:
"Would you like some music?"
Song Zimo also had the same idea: "The music is ringing!"
There is a set of speakers in the corner of the operating room, connected to the computer.
Director Tan started looking for songs in the music library folder on his computer.
"Never Give Up" is for critically ill patients.
Celine Dion's "My Heart Will Go On", a song commonly used in cardiac surgery.
"Stay Alive" by the Bee Gees, the signature music of Orthopedic Traumatology.
"Baby One More Time" by Britney Spears, a song used to induce labor in obstetrics, how come it is placed here?
"Come Back Soon", a song used by the emergency department to celebrate successful rescue operations.
Director Tan is also a person of good taste. The music cannot be casual. What kind of music should be used?
"This patient is very nervous, Coldplay's "Cure You"!" Song Zimo is very familiar with the music in the operating room.
Director Tan finally found the song "Cure You", and the music sounded in the operating room.
"What kind of music does Professor Yang usually like to listen to during surgeries?" Director Tan thinks that he should prepare it in advance next time.
Song Zimo said: ""High Mountains and Flowing Waters""
"Do you want to change?" Director Tan asked.
Song Zimo told Director Tan: "No, I will listen to this song for the patient to relieve his tension."
Finally, Song Zimo and Xu Zhiliang completed the remaining installation of the external fixator, attached the fixing clip, placed the connecting rod, and tightened the nut.
A complex and complete orthopedic external fixator has been installed.
In fact, the Tianji robot only completes key steps, and many steps still need to be completed manually.
Therefore, there is still a lot of room for improvement.
The entire operation was completed in ten minutes, with a blood loss of less than 5 ml. Precise nail placement and osteotomy left the joint capsule, ligaments and other stable structures intact.
These complete structures will be corrected as the bones correct and in accordance with Ilizarov's principle.
Director Tan watched the operation process in full and had to admit that he had completed hundreds of operations, but he was still not as skilled as Yang Ping. The gap was quite big.
The gap between veteran drivers and professional racing drivers.
It's really enjoyable to watch Yang Ping perform surgery. Under his control, the robotic arm can really do whatever he wants and become an extension of the real doctor's hand.
No wonder, he can control Tianji's robotic arm to draw a human anatomy diagram.
You can also control Leonardo da Vinci's four robotic arms to complete that hot dance in a small glass bottle.
The music still reminded me, and Yang Ping came to Fang Faquan's head.
"The operation is done!"
"Success?"
Fang Faquan asked worriedly, it seemed like it had just started and it was over? It didn’t feel like anything.
"Very successful!"
Director Tan took the call.
The music kept playing, and Fang Faquan felt very comfortable. In his mind, he returned to his small mountain village with his healthy legs and his beautiful wife.
