godfather of surgery

Chapter 556
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 entrust these matters to a reliable and capable person.

Obviously, Huang Jiacai is the best choice.

Yang Ping is 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 among several major orthopedic consumables giants to squeeze out a living space between the giants.

This sliver of living space allowed Ruixing to survive from desperation. Not only was it not wiped out, but it made a profit, and it was also buffered in terms of time.

Within the limited buffer time, Huang Jiacai reused Chen Zhi to form a strong R&D team to systematically develop orthopedic instruments. After the developed instruments were finalized, a certain number of finished products were produced and placed in the warehouse, which could be sterilized and put into clinical use at any time.

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 replace it at any time. Although new products may not be so mature, as long as they can replace them, they will not be afraid of threats.

For this research and development team, Huang Jiacai took a series of measures with great pains in order to stabilize people's hearts and make them feel at ease in research and development.

The fixed salaries of R&D personnel can ensure that they basically have no worries about food and clothing. Once the designed medical devices are launched on the market and make profits for the company, they will also receive a large amount of bonuses.

In terms of sales, Huang Jiacai also made drastic reforms. He deeply integrated his ideas into the reforms. He built several powerful sales teams and designed a standard sales and distribution model.

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

Even the distribution models of several giants are regarded as amateur level in front of Huang Jiacai.

With the support of this warehousing and distribution system, elite salesmen rushed to attack the city, and the market share continued to expand.

Even if it seizes the market, Ruixing's method is not to do things in its own way, but to establish a set of procedures. To win a hospital, how to go through the whole process, what important departments to conquer, and what methods to use, Huang Jiacai made all these scientific and technological, standardization.

Ruixing Company has specially established a department similar to an intelligence agency to collect information on target customers and provide strong intelligence support for sales staff.

The dean of the target hospital, the director of the equipment department, and the director of the orthopedics department were all caught by this department.

Then the sales force is ready, and the intelligence department continues to provide support in the meantime.

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

With the support of Huang Jiacai's commercial talent, Yang Ping's technical talent will 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 operation, design the nail placement point and direction, and determine the precise osteotomy line.

After the operation, Yang Ping will feed back the data to Professor He according to 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 digital human to provide support for Yang Ping's difficult surgery.

The surgical data provided by Yang Ping to Professor He is the best in the world. With such high-quality data feedback, it is only a matter of time before Professor He's calculation model will become world-leading.

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

Cui Xubing finally understood why his son always had a bad complexion and poor brain function. It turned out that the severe spinal deformity affected the heart and lung function, which caused insufficient oxygen supply and affected the development of the brain and body.

This Cui Xubing is very suspicious. He thinks that he is tall and straight and smart. How come the son he gave birth to is not only congenitally deformed, but also lags behind his peers in IQ. He once suspected that the son was not his.

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

Cui Xubing saw his wife's former college boyfriend, who had a bit of shoulder bumps, and Cui Xubing concluded that the bumps were caused by scoliosis.

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

Are you afraid that you will help someone else raise their son?

Old Cui would not do such stupid things.

However, Old Cui was quite cautious, and secretly took his son out for a paternity test without saying a word.

The final paternity test results --- the son was born to Cui Xubing.

Old Cui broke out in a cold sweat, but fortunately, the doubts were carried out quietly, otherwise he would be mistaken for his cleverness, and his good family would be broken up alive.

When the operation began, the couple sat in the family waiting area outside the operating room.

"You said our son's surgery is fine, right? 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 all the folded people straightened and stood up. My son's operation should not be a problem, let alone 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 technique is unreliable, how dare they accept gifts?"

Old Cui Jianghu has rich experience, looking for someone to do things, and people dare to accept gifts, which shows that this matter is still sure.

Also!

Guo Liu nodded.

The red envelope is like a reassurance, which reassures Cui Xubing and his wife.

Six-year-old Cui Shukai lay on his back on a spinal positioner.

For orthopedic operations, the operating table and body position frame are made of X-ray transparent materials, and no developed metal parts can be used.

The [-]D reconstructed image of Cao Shukai's spine is presented on the screen, which can be observed from different 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 mechanical arm starts to match the position. The direction of the puncture needle is consistent with the blue line in the image. The robot automatically calibrates and locks the direction of the mechanical arm when it is correct.

The puncture needle moved forward slowly, just touching Cui Shukai's skin, Yang Ping stopped it.

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

On the real-time fluoroscopy image, it can be seen that the needle tip passes through the skin and then reaches 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 operation area.

Song Zimo started the manual steps, screwing in 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 on the robotic arm.

The robotic arm aimed at the blue line again, and after calibration, it inserted through the sheath and began to rotate slowly, drilling in and out, rotating for a while, stopping, and then continuing to rotate forward.

Under fluoroscopy, you can watch the drill pass through the pedicle and enter the vertebral body. The puncture point and direction are perfect.

When the drill bit enters about [-]/[-] of the vertebral body, it stops automatically under the control of the depth-limiting program.

Yang Ping rotated the [-]D reconstruction image, the pedicle screw was in the only bony canal, surrounded by bone on all sides, and the position was very central.

The drill bit is also a guide pin, along which the mechanical arm is screwed into the pedicle screw.

At this time, part of the pedicle screw remains outside the skin, and part has entered the vertebral bone.

With the mechanical arm withdrawn, Song Zimo manually screwed in the anti-slip device. This anti-slip device can limit the accidental penetration of the pedicle screw, so that it penetrates too deep into the vertebral body and breaks through the bone in front of the vertebral body, damaging the aorta and vena cava at the front of the vertebral body. .

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

The function of this anti-slip device is very small, and it is also the core of the safety guarantee of this equipment.

The first percutaneous pedicle screw was placed successfully.

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

The second step is osteotomy, which is also the most risky operation.

Ultrasonic osteotomy is used for osteotomy with minimally invasive incision. The biggest advantage of ultrasonic osteotomy is that it can eat hard but not soft.

It can cut the bone without damaging the surrounding soft tissues such as nerves and blood vessels.

Song Zimo was in charge of cutting the skin, retracting the small opening, and allowing the robotic arm to cut the bone.

Osteotomies of different positions and directions are completed for each deformed vertebra, after the osteotomy is completed.

The rest of the work can only be done manually --- assembling the external fixator.

It's also a very delicate job.

"The professor initially wanted to use memory alloy as an external fixator, so that some young children do not need osteotomy for orthopedics, but that kind of 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 has low material requirements, and the orthopedic 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 deformity is distributed to each vertebra, so the speed of correction is very fast."

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

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

The products at that time were designed without osteotomy, relying on orthotics to stretch soft tissues.

However, the required tensile force is relatively large, and some of the parts need to use 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 the materials that meet the requirements are helpless. There is no mass production, and it is still an experimental product, so the supply chain is immature.

Moreover, although that kind of external fixator is perfect and does not require osteotomy, it takes a long time for orthopedics, and it takes half a year to move for successful orthopedics.

Later, Yang Ping took second place and used the bone transport at the osteotomy site to achieve orthopedic correction. Although osteotomy was still required, this kind of osteotomy was completely different from traditional osteotomy in terms of method and purpose.

The current external fixator for the spine is indeed the most practical and does not have high requirements for materials. The materials for the external fixator for the extremities are completely satisfactory, and the orthopedic time is short. Generally, the orthopedic is completed within three months.

Therefore, sometimes the most perfect technology is not necessarily the best considering cost and efficiency.

After the external fixator was installed, the blood loss in the whole operation was only tens of milliliters. The operation with the highest risk in spinal surgery ended so quickly.

It was hard for Director Tan and Director Qin of the spinal surgery department to believe that this artifact could straighten Cui Shukai's severe scoliosis in just three months.

If it can be done, it will really be a subversive technological innovation in spine surgery.

"Old Xu, the Publicity Department wants to publicize this technology. They want to give this spinal external fixator a famous name for easy publicity. What would you call it?"

Song Zimo said while stitching up the small incision.

Xu Zhiliang clicked and helped to cut the thread: "Straighten the magic weapon!"

"Straighten the artifact?"

Song Zimo thought for a while and said, "Why doesn't the name sound like a spinal surgery department, but a bit like the name of a psychology department?"

"That's right, when people see the straightening artifact, they don't immediately think of straightening the spine, but straighten other parts." Xiao Wu also felt that Song Zimo was right.

"Other parts? Which part do you need to straighten?"

The itinerant nurse also came to join in the fun, and felt that they could not understand their chat.

"When the adults are chatting, the little girls don't interrupt, there are many places that we need to straighten."

Song Zimo said to the perplexed itinerant nurse.
