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,
Assess the situation, adopt the correct strategy, take advantage of the contradictions between the major orthopedic consumables giants, play both sides, and squeeze out a little living space in the cracks of the giants.
This little bit of living space allowed Rui Xing to survive the desperate situation. Not only was it not eliminated, 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,
Systematically develops orthopedic devices. After the developed devices are finalized, a certain number of finished products are produced and placed in the warehouse, ready for sterilization and clinical use at any time.
This kind of strategic reserve allows Ruixing to put an end to the days of being on tenterhooks. Once Ruixing gets into trouble with a few giants, Ruixing'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 also took great pains to stabilize people's hearts and allow them to develop with peace of mind.
Take a series of measures.
The fixed salary of R&D personnel can ensure that they have basic food and clothing needs.
Once the designed medical device is brought to market,
If you make money for the company, you will also get a lot of bonuses.
In sales,
Huang Jiacai also made drastic changes and incorporated his ideas deeply 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 it seizes the market, Ruixing's approach is not to work independently, but to establish a set of processes. If you want to win a hospital, how will the entire process go?
What important departments should be conquered?
What techniques to use?
Huang Jiacai made all this scientific, technical and standardized.
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.
Then the sales staff is prepared, and the intelligence department continues to provide support during this period.
This scientific sales system is powerful 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 circle.

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 normal to use computer digital humans 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 has also been 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 brain and body development.
Cui Xubing was very suspicious. He thought 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 overnight, and came home the next day.
Cui Xubing saw his wife's former boyfriend in college who had some uneven shoulders. Cui Xubing concluded that the uneven shoulders were caused by scoliosis.
The time when his son was born 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 others raise their son?
Lao Cui will 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 son.
Lao Cui was so frightened that he broke out in a cold sweat. Fortunately, all these suspicions were carried out quietly, otherwise his cleverness would be misled by his cleverness, and the good family would be broken up.
When the operation started, the couple sat in the family waiting area outside the operating room.
"You said our son's surgery is okay, but my heart is pounding?" 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 unreliable, how dare I accept the gift?"
Lao Cui has rich experience in the world. If he is looking for someone to do something, and he dares to accept the gift, it means that he is still sure of the matter.
Yes!
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 observed from various angles.
The operating room is busy, and Yang Ping has 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 that the needle tip passes through the skin and then reaches the puncture point on the back of the vertebra.
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 satisfied.
Xu Zhiliang has 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 about one-half of the vertebral body, it automatically stops under the control of the depth limit program.
Yang Ping's rotated three-dimensional reconstruction 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 mechanical arm screws into 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 have different directions, and the arrangement generally presents a large C-shape.
The second step is osteotomy, which is also the riskiest operation.
Osteotomy uses ultrasonic osteotomy under minimally invasive incision. The biggest advantage of ultrasonic osteotomy is that it can eat hard and not soft.
It can cut bones without damaging surrounding nerves, blood vessels and other soft tissues.
Song Zimo is responsible for incising the skin, retracting the small opening, and allowing 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 initially wanted to use memory alloy as an external fixator, so that orthopedics for some young children 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 deformity correction 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 designed at that time did not require osteotomy and relied on orthotics to stretch the soft tissue.
However, the required pulling 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. To successfully correct the correction, it takes half a year and a year.
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 satisfied, 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 publicize 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!"
"Break the artifact straight?"
Song Zimo thought for a while and said: "Why does this name sound like a name for a spinal surgery department, but more like a name for a psychology department?"
"Yes, when people look at the straightening artifact, the first thing they think of is 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 traveling 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.
