Yang Ping's interests are all focused on medicine, and 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 things to a reliable and competent 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 judged the situation, adopted the correct strategy, and took advantage of the contradictions between several major orthopedic consumables giants, left and right, and squeezed out a trace of living space in the cracks of the giants.

This glimmer of living space allowed Ruixing to survive in a desperate situation, not only was it not eliminated, but it was profitable, and it was also buffered in time.

In the limited buffer time, Huang Jiacai reused Chen Zhi to set up a strong R&D team to systematically develop orthopedic devices, and after the developed devices were finalized, a certain number of finished products were produced and placed in the warehouse, which could be sterilized at any time and entered into clinical use.

This kind of strategic reserve allows Ruixing to end the days of fear, once it has a bad relationship with several giants, Ruixing's own products can be replaced at any time, although new products are not necessarily so mature, but as long as they can be replaced, they are not afraid of threats.

For this R&D team, Huang Jiacai also took great pains to take a series of measures in order to stabilize people's hearts and let them feel at ease in research and development.

The fixed salary of R&D personnel can ensure that they have no worries about food and clothing, and once the designed medical device is introduced to the market, it will also receive a large amount of bonuses for the company's profit.

In terms of sales, Huang Jiacai is also a drastic reform, deepening his own concept into the reform, he has built several strong sales teams, and designed a set of standard sales and distribution models.

The company practices Internet thinking, builds a national warehousing and distribution network platform, establishes central warehouses in several major regions, and then establishes satellite warehouses near hospitals.

Even the distribution model of several giants, in front of Huang Jiacai, is regarded as an amateur.

With the support of this warehousing and distribution system, elite salesmen have slammed and stormed, attacking the city, and the market share has been expanding.

Even if it is to seize the market, Ruixing's method is not to do it separately, but to establish a set of processes, to win a hospital, how to go through the whole process, what important departments to overcome, what methods to use, Huang Jiacai will all this scientific, technical, and standardized.

Ruixing company has set up a department similar to an intelligence agency to collect information about target customers and provide strong intelligence support for sales personnel.

The director of the target hospital, the director of the instrument department, and the director of the orthopedic department were all touched by this department.

Then the salesperson came prepared, and the intelligence unit continued to provide support.

This kind of scientific sales system is powerful, and it is invincible to seize the market, and its performance is rising.

With the support of Huang Jiacai's business talent, Yang Ping's technology 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 placement point and nail direction, and determine the accurate osteotomy line.

After the operation, Yang Ping will feed back the data to Professor He according to the actual situation during the operation.

This kind of interaction allows Nandu Medical University to continuously improve and optimize the modeling algorithm and improve the level of core technology.

In the future, the use of computer digital people to provide support for Yang Ping's difficult surgery will become the norm.

The surgical data provided by Yang Ping to Professor He is the best in the world, and with this high-quality data feedback, it is only a matter of time before Professor He's computational model reaches the world's leading position.

Cui Shukai's preoperative examination has been completed, and the spinal deformity has affected the cardiopulmonary function, the lung capacity is extremely small, and the diastolic heart has also been affected.

Cui Xubing finally understood why his son always had a bad face and a bad brain, because the severe spinal deformity affected the heart and lung function, which caused insufficient oxygen supply, resulting in brain and physical development.

This Cui Xubing is very suspicious, he thinks that he is tall and smart, how did he give birth to a son who is not only congenitally deformed, but also a little behind his peers in IQ, and he once suspected that his son was not his own.

The worst thing is that my wife attended a class reunion, spent the night outside, and only came home the next day.

Cui Xubing met his wife's former boyfriend in college, who had a bit of high and low shoulders, and Cui Xubing concluded that the high and low shoulders were caused by scoliosis.

The time of his son's birth coincided with that class reunion, and the clever Cui Xubing connected several things together and came to an astonishing conclusion.

I'm afraid I'm not helping someone else raise a son?

Lao Cui doesn't do this kind of stupid thing.

However, Lao Cui was quite cautious, did not say anything, and secretly took his son out for a paternity test.

In the end, the paternity test results --- son was born to Cui Xubing.

Lao Cui was scared into a cold sweat, fortunately, this suspicion was carried out quietly, otherwise he would be mistaken by being smart, and a good family would be broken up alive.

At the beginning of the operation, the couple sat in the waiting area for their families outside the operating room.

"You said our son's surgery is fine, my heart is pounding?" Guo Liu was a little uneasy.

Cui Xubing was very calm: "Don't worry, Professor Yang personally took charge of the surgery, and the folding people were straightened and stood up, my son's surgery should not be a problem, not to mention that it is still minimally invasive." ”

"Is this new technology reliable?" Guo Liu is still not at ease.

Cui Xubing smiled mysteriously, saw that there was no one next to him, and said in his wife's ear: "If this technology is unreliable, people dare to accept gifts?" ”

Lao Cui Jianghu is experienced, looking for someone to do things, and people dare to accept gifts, which shows that this matter is still certain.

Also!

Guo Liu nodded.

The red envelope is like a reassuring pill, which makes Cui Xubing and his wife very relieved.

Six-year-old Cui Shukai lies on his stomach on a spinal position.

For orthopedic surgery, the operating table and body frame are made of materials that can transmit X-rays, and metal parts cannot be used.

A 3D reconstruction of Cao's spine is presented on the screen and can be viewed from different angles.

The operating room is busy, and Yang Ping has already started the operation.

A blue line threads out from 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 of the image, and the robot automatically calibrates and locks the direction of the robotic arm after it is correct.

The puncture needle moved forward slowly, and just after touching Cui Shukai's skin, Yang Ping asked it to stop.

Song Zimo stabbed a small hole in the skin with a sharp knife, and Yang Ping manipulated the robotic arm to make the puncture needle advance precisely along the established route.

On the real-time fluoroscopic image, you can see the tip of the needle passing through the skin and then against the puncture point behind the vertebrae.

At this time, Song Zimo removed the puncture needle, and Yang Ping's robotic arm retreated, away from the operation area.

Song Zimo began the manual steps, screwing into the sheath along the puncture needle step by step, from thin to thick, and then pulling out the puncture needle after being satisfied.

Xu Zhiliang has already installed a drill bit on the robotic arm.

The robotic arm was aimed at the blue line again, and after calibration, it reached through the sheath and began to rotate slowly, drilling and advancing, turning for a while, stopping, and then continuing to rotate forward.

Under perspective, you can see the drill bit pass through the pedicle into the vertebral body, and the puncture point and direction are perfect.

When the drill bit enters the vertebral body about half of the way, it automatically stops under the control of the depth limiting program.

Yang Ping rotated the three-dimensional reconstruction image, and the pedicle was nailed in the only bony duct, surrounded by bone on all sides, and the position was very centered.

The drill bit is also a guide needle, and along the guide needle, the robotic arm is screwed into the pedicle nail.

At this point, part of the pedicle nail remains outside the skin, and part of it has entered the vertebral bone.

The mechanical arm was withdrawn, and Song Zimo manually screwed in the anti-slip device, which can limit the accidental penetration of the pedicle nails, so as to enter the vertebral body too deep and break through the bone in front of the vertebral body, damaging the aorta and vena cava on the front side of the vertebral body.

If there is no anti-slip device, even if the pedicle nail is in a good position now, it will inevitably go deeper and deeper with the child's activities in the future, and once the aorta and vena cava are damaged, it will be life-threatening.

The role of this anti-slip device is very small, and it is also the core of the safety and security of this set of equipment.

The first percutaneous pedicle nail was successfully placed.

All the vertebrae involved in the spinal deformity are implanted pedicle nails, because the vertebrae are deformed, and all these nails are left on the outside in different directions, and the arrangement generally presents a large C-shape.

The second step is an osteotomy, which is the riskiest procedure.

Osteotomy uses minimally invasive incision under ultrasonic bone knife osteotomy, and the biggest advantage of ultrasonic bone knife is that it eats hard rather than soft.

It can be an osteotomy without damaging the surrounding soft tissues such as nerves and blood vessels.

Song Zimo is responsible for cutting open the skin, opening the small incision, and letting the robotic arm perform the osteotomy.

Each deformed vertebrae is osteotomy with different parts and directions, and the osteotomy is completed.

The rest of the work can only be done manually ---- assemble the outer fixator.

It's also a very delicate job.

"The professor originally wanted to use memory alloy to do the external fixator, so that some young children's orthopedics do not need osteotomy, but the external fixator is too complicated, and the orthopedic time is too long, considering the practicality, he gave up the original design, the current external fixator, the material requirements are low, and the orthopedic time is short, although the osteotomy is required, but both safety and osteotomy purposes are different from traditional surgery."

"With osteotomy, the correction of the deformity is dispersed to each vertebrae, so the speed of orthopedics is very fast."

Song Zimo and Xu Zhiliang installed the outer fixture, or checked the scale of each knob, and asked the itinerant nurse to help record.

Yang Ping's original external spinal fixator design was more perfect, but perfection is not necessarily the best.

At that time, the product was designed to rely on orthosis to stretch the soft tissues without the need for osteotomy.

However, the required stretching force is relatively large, and several of the components need to use special memory alloys, this memory alloy, Huang Jiacai also found raw materials, a material laboratory of Northwestern Polytechnical University has developed this alloy, but the materials that meet the requirements are not mass-produced, and they are still in experimental products, so that the supply chain is immature.

Moreover, although the external fixator is perfect and does not require osteotomy, the orthopedic time is long, and it takes half a year to move it for the orthopedic to be successful.

Later, Yang Ping retreated to the second place, using the bone transportation at the osteotomy to achieve orthopedics, although osteotomy is still needed, but this osteotomy is completely different from the traditional osteotomy, both in terms of method and purpose.

The current external spinal fixator is indeed the most practical, and the material requirements are not high, and the ordinary external fixator material of the limbs is fully satisfied, and the orthopedic time is short, and the orthopedic is generally completed within three months.

So, sometimes the best technology, considering cost, efficiency, etc., is not necessarily the best.

After the installation of the external fixator, the bleeding of the entire operation was only a few tens of milliliters, and the most risky operation in spine surgery ended so quickly.

Director Tan and Director Qin of the Spine Surgery Department found it hard to believe that this artifact could straighten Cui Shukai's severe scoliosis in just three months.

If it does, it will be a disruptive technological innovation in spine surgery.

"Lao Xu, the propaganda department wants to publicize this technology, they want to give this external spinal fixator a loud name to facilitate publicity, what do you say is it called?"

Song Zimo said while stitching up the small incisions.

Xu Zhiliang clicked and helped cut the thread: "Straighten the artifact!" ”

"Straighten the artifact?"

Song Zimo thought for a while and said, "Why does this name sound like it doesn't look like a spine surgery, it's a bit like the name of a psychology department?" ”

"Also, when people look at the straightening artifact, they don't think of straightening the spine at the first time, but straightening other parts." On the side, Xiao Wu also felt that Song Zimo was right.

"Other parts? Is there any other part that you need to straighten? ”

The itinerant nurses also came to join in the fun, thinking that they couldn't understand how they were chatting.

"Adults chat, little girls don't interject, there are many places where we need to straighten."

Song Zimo said to the itinerant nurse with a puzzled face.
