Chapter 556 Straightening the Artifact
Yang Ping's interests are all focused on medicine. He really has no interest in business, let alone the energy to participate in these things.
Therefore, it is the best choice to leave these matters to a reliable and capable person.
Obviously, Huang Jiacai is the best choice.
Yang Ping was very satisfied with Huang Jiacai's performance.
After Huang Jiacai took over Ruixing, he assessed the situation and adopted the correct strategy. He took advantage of the contradictions between the major orthopedic consumables giants and squeezed out a living space in the cracks between the giants.
This little bit of living space allowed Ruixing to survive the desperate situation. Not only was it not wiped out, but it was profitable and buffered in time.
Within the limited buffer time, Huang Jiacai reused Chen Zhi to form a strong R&D team to systematically develop orthopedic devices. After the developed devices were finalized, a certain number of finished products were produced and placed in the warehouse, ready for sterilization and clinical use at any time.
This kind of strategic reserve allows Rui Xing to put an end to its days of fear. Once it gets into trouble with several giants, Rui Xing's own products can replace it at any time. Although new products may not be that mature, as long as they can replace them, they are not afraid of threats.
For this R&D team, Huang Jiacai took great pains to take a series of measures in order to stabilize people's hearts and allow them to develop with peace of mind.
The fixed salary of R&D personnel can ensure that they have basic food and clothing. Once the designed medical device is launched on the market and makes profits for the company, they will also receive large bonuses.
In terms of sales, Huang Jiacai also made drastic reforms and deepened his ideas into the reform. He built several strong sales teams and designed a standard sales and distribution model.
The company practices Internet thinking and builds a national warehousing and distribution network platform, establishing central warehouses in several major regions, and then establishing satellite warehouses near hospitals. The construction and distribution processes of these warehouses are all in accordance with unified standards to allow the distribution of medical devices to enter Standardized management.
Even the delivery models of several giants were regarded as amateur level in front of Huang Jiacai.
With the support of this warehousing and distribution system, elite salesmen rushed hard, conquered the city, and continued to expand their market share.
Even if they seize the market, Ruixing's approach is not to work independently, but to establish a set of processes. To win a hospital, how should the entire process go, what important departments should be conquered, and what techniques should be used. Huang Jiacai has made all this scientific and technical. standardization.
Ruixing Company has specially established a department similar to an intelligence agency to collect information about target customers and provide sales staff with strong intelligence support.
The director of the target hospital, the director of the device department, and the director of the orthopedics department were all thoroughly investigated by this department.
The salesperson then comes prepared, while this intelligence unit provides ongoing support.
This scientific sales system is powerful, invincible and invincible in seizing the market, and its performance is rising steadily.
With the support of Huang Jiacai's business talent, Yang Ping's technical talent can continue to be realized, thus forming a virtuous cycle.
——
Next, the Digital Medicine Laboratory of Nandu Medical University used digital human technology to edit the data package for Cui Shukai’s surgery, design the nail insertion points and directions, and determine the precise osteotomy line.
After completing the operation, Yang Ping will feedback the data to Professor He based on the actual situation during the operation.
This interaction allows Nandu Medical University to continuously improve and optimize the modeling algorithm and improve the level of core technology.
In the future, it will become the norm to use computer digits to provide support for Yang Ping's difficult surgeries.
The surgical data provided by Yang Ping to Professor He is the best in the world. With this high-quality data feedback, it is only a matter of time before Professor He's calculation model reaches the world's leading level.
Cui Shukai's preoperative examination has been completed. The spinal deformity has affected the cardiopulmonary function, the vital capacity is extremely small, and the diastole of the heart is also affected.
Cui Xubing finally understood why his son always looked bad and had trouble functioning mentally. It turned out that severe spinal deformity affected the heart and lung function, resulting in insufficient oxygen supply and affecting the development of the brain and body.
This Cui Xubing was very suspicious. He thought that he was tall and smart, but how could he give birth to a son who was not only born with congenital malformations, but also lagged behind his peers in terms of IQ? He once suspected that the son was not his.
The most terrible thing is that my wife attended a class reunion, stayed out all night, and didn't come home until the next day.
Cui Xubing saw that his wife's former boyfriend in college had some uneven shoulders. Cui Xubing concluded that the uneven shoulders were caused by scoliosis.
The time of his son's birth coincided with that class reunion. The clever Cui Xubing connected several events and came to a surprising conclusion.
Are you afraid that you are helping someone else raise their son?
Lao Cui would not do such stupid things.
However, Lao Cui was still cautious and did not say anything, secretly taking his son out for a paternity test.
The final paternity test result - the son is Cui Xubing's biological child.
Lao Cui was so frightened that he broke into a cold sweat. Fortunately, all these suspicions were carried out quietly, otherwise his cleverness would be misled by his cleverness, and his good family would be completely broken up.
When the operation began, the couple sat in the family waiting area outside the operating room.
"You said our son's surgery is fine, are you? I'm pounding in my heart?" Guo Liu was a little uneasy.
Cui Xubing was very calm: "Don't worry, Professor Yang performed the surgery himself, and the folded people were straightened up to stand up. This surgery for my son should not be a problem, not to mention it is minimally invasive."
"Is this new technology reliable?" Guo Liu was still worried.
Cui Xubing smiled mysteriously. Seeing that there was no one around, he whispered in his wife's ear: "If this technology is not reliable, how dare I accept the gift?"
Lao Cui has a lot of experience in the world. When he finds someone to do things, he dares to accept gifts, which shows that he is still sure about the matter.
Too!
Guo Liu nodded.
The red envelope is like a reassurance, which makes Cui Xubing and his wife feel very relieved.
Six-year-old Cui Shukai lies on the spinal position frame.
In all orthopedic surgeries, the operating table and positioning frame are made of materials that are transparent to X-rays, and metal parts that can be developed cannot be used.
The three-dimensional reconstructed image of Cao Shukai's spine is displayed on the screen and can be viewed from various angles.
The operating room was busy, and Yang Ping had already started the operation.
A blue line passes through the center of the pedicle. Under the guidance of the antenna, the robotic arm begins to match the position. The direction of the puncture needle is consistent with the blue straight line in the image. The robot automatically calibrates and locks the direction of the robotic arm after it is correct.
The puncture needle advanced slowly, and as soon as it touched Cui Shukai's skin, Yang Ping asked it to stop. Song Zimo used a sharp knife to make a small incision in the skin, and Yang Ping controlled the robotic arm to accurately advance the puncture needle along the established route.
In the real-time fluoroscopic image, you can see the needle tip passing through the skin and then reaching the puncture point on the back of the vertebrae.
At this time, Song Zimo removed the puncture needle, and Yang Ping's robotic arm retreated away from the surgical area.
Song Zimo started the manual steps, screwing the sheath into the sheath step by step along the puncture needle, from thin to thick, and then pulled out the puncture needle when he was satisfied.
Xu Zhiliang has already installed a drill bit on the robotic arm.
The robotic arm aims at the blue line again. After calibration, it extends through the sheath and starts to rotate slowly, drilling while drilling, rotates for a while, stops, and then continues to rotate forward.
Under fluoroscopy, you can watch the drill bit pass through the pedicle and enter the vertebral body. The puncture point and direction are perfect.
When the drill bit enters approximately one-half of the vertebral body, it automatically stops under the control of the depth limit program.
Yang Ping's rotated three-dimensional reconstructed image shows that the pedicle screw is in the only bony channel, surrounded by bone on all sides, and is very centrally located.
The drill bit is also a guide pin. Following the guide pin, the robotic arm screws in the pedicle screw.
At this time, part of the pedicle screw remains outside the skin, and part has entered the vertebral bone.
After the robotic arm withdrew, Song Zimo manually screwed in the anti-slip device. This anti-slip device can limit the accidental penetration of the pedicle screws, thereby entering the vertebral body too deep and breaking through the bone in front of the vertebral body, damaging the aorta and vena cava in the front of the vertebral body. .
Without this anti-slip device, even if the pedicle screw is in a good position now, it will inevitably penetrate deeper with the child's activities in the future. Once the aorta and vena cava are damaged, life will be in danger.
The role of this anti-slip device is very small, and it is also the core of the safety of this set of equipment.
The first percutaneous pedicle screw was successfully placed.
All vertebrae involved in spinal deformity are implanted with pedicle screws. Because the vertebrae are deformed, all the screws left outside are in different directions, and the arrangement generally presents a large C shape.
The second step is osteotomy, which is also the riskiest operation.
Osteotomy is performed using an ultrasonic osteotome under a minimally invasive incision. The biggest advantage of the ultrasonic osteotome is that it eats hard bones but not soft ones.
It can cut bones without damaging surrounding nerves, blood vessels and other soft tissues.
Song Zimo is responsible for incising the skin and retracting the small opening to allow the robotic arm to perform osteotomy.
Each deformed vertebra undergoes osteotomy in different locations and directions. After the osteotomy is completed.
The remaining work can only be done manually - assembling the external fixator.
This is also a very delicate job.
“The professor originally wanted to use memory alloy as an external fixator, so that some young children’s orthopedics would not require osteotomy. However, that kind of external fixator was too complicated and the correction time was too long. Considering practicality, he gave up the original design. , the current external fixator has low material requirements and the correction time is short. Although osteotomy is required, it is different from traditional surgery in terms of safety and purpose of osteotomy. ”
"Using osteotomy, the correction of the deformity is spread to each vertebra, so the correction speed is very fast."
After Song Zimo and Xu Zhiliang installed the external fixator, they checked the scales of each knob and asked the circulating nurse to help record them.
Yang Ping's original spinal external fixator design was more perfect, but perfection is not necessarily the best.
The product at that time was designed to eliminate the need for osteotomy and rely on orthotics to stretch soft tissues.
However, the required tensile force is relatively large, and several parts require special memory alloys. Huang Jiacai also found raw materials for this memory alloy. A materials laboratory at Northwestern Polytechnical University has developed this alloy, but materials that meet the requirements cannot be found. There is no mass production and it is still an experimental product, so the supply chain is immature.
And although that kind of external fixator is perfect and does not require osteotomy, the correction time is long, and it takes half a year for the correction to be successful.
Later, Yang Ping retreated to the next best option and used bone transfer at the osteotomy site to achieve correction. Although osteotomy was still required, this type of osteotomy was completely different from traditional osteotomy in both method and purpose.
The current spinal external fixator is indeed the most practical and does not have high material requirements. The materials of ordinary limb external fixators are fully satisfactory, and the correction time is short, and the correction is usually completed within three months.
Therefore, sometimes the most perfect technology may not necessarily be the best considering cost, efficiency, etc.
After the external fixator was installed, the blood loss during the entire operation was only a few dozen milliliters. An operation with the highest risk in spinal surgery ended so quickly.
Director Tan and Director Qin from the spinal surgery department found it hard to believe that this magical tool could straighten Cui Shukai's severe scoliosis in just three months.
If it can really be done, it will really be a disruptive technological innovation in spine surgery.
"Old Xu, the Publicity Department wants to promote this technology. They want to give this spinal external fixator a loud name to facilitate publicity. What do you think it should be called?"
Song Zimo said while sewing up the small incision.
Xu Zhiliang made a click and helped to cut the thread: "Straighten the artifact!"
"Straighten the artifact?"
Song Zimo thought for a moment and said, "Why does this name not sound like a name for spinal surgery, but a bit like a name for a psychology department?"
"Yes, when people look at the straightening artifact, they will not immediately think of straightening the spine, but straightening other parts." Xiao Wu also felt that Song Zimo was right.
"Other parts? Which parts need you to straighten?"
The circulating nurse also came to join in the fun and felt that they couldn't understand what they were talking about.
"When adults are chatting, little girls, please don't interrupt. There are many things we need to straighten out."
Song Zimo said to the visiting nurse who looked confused.
