The last guest was transferred to the airport, and the academic meeting officially ended.

More than 2,000 doctors who attended the meeting ended the two-day meeting and hurried back to the hospital to start their busy work.

Yang Ping dragged his tired body home and lay down on the sofa, not wanting to get up at all.

"Dingdong, stage task: help Sanbo Hospital establish the strongest trauma orthopedics department in G City, the task is complete! Reward 500,000 points! ”

"Comes with a silver treasure box - the third part of the system super cultivation Dafa, auxiliary inspection and training!"

"The function of the space operating room has been expanded, and the newly launched function - simulated surgery."

"Ding-dong! New stage mission: Win the championship of the National Golden Knife Award Competition. ”

A series of mechanical female voices and subtitles appeared, which overwhelmed Yang Ping.

The first stage of the task was finally completed, step by step, and it was not easy to complete, and even a little difficult.

In this way, as long as you want to get the gain, you must give, and the difference lies in the content of the payment.

Without any respite, the system issued a second stage of the task: to win the championship of the National Golden Knife Award.

The difficulty of this quest has increased a lot compared to the first one.

In order to win the National Golden Knife Award, one must be able to skillfully perform all orthopedic surgeries, including scoliosis orthopedics.

The scoliosis orthopedics, the general affiliated hospital of the medical university, the number of cases per year is pitiful, ranging from a few to a dozen, and most of the cases are concentrated in the magic capital, the imperial capital and several top hospitals in the west, so the annual Golden Knife Award champion always rotates in these hospitals, and has never fallen outside these top hospitals.

Yang Ping was very curious, what exactly is the silver treasure box --- auxiliary inspection training?

He entered the system space and read the introduction of auxiliary inspection training through the light screen.

The so-called auxiliary examination is such as blood routine, biochemistry, liver and kidney function, electrocardiogram, X-ray, CT, MRI, color ultrasound, etc., all with the help of laboratory and equipment examination.

This training includes the theory and operation of these examinations, as well as the analysis and interpretation of the data.

The system links anatomy, physiology, pathology, patients, symptoms and signs, and auxiliary examinations, and establishes a complete logical model with basic theories such as anatomy and physiology as the core, and symptoms and signs and auxiliary examinations as external manifestations.

Through this model, doctors can develop strong logical thinking skills, and be able to analyze the deep reasons behind each symptom, sign and examination indicator.

This training is long-term and gradual, not in a hurry, Yang Ping put it down for the time being, and will train slowly in the future.

What is the new simulated surgery function? Yang Ping wanted to try it, and he clicked the "Simulated Surgery" button on the light screen with his mind.

In an instant, entering the operating space, it was empty, there was nothing, what was going on?

"The function of simulated surgery needs to be activated by ideas, which is divided into scene simulation and free simulation, scene simulation, simulating a certain surgical scene in reality; Free simulation, you can freely choose the test subject, instruments, and equipment to simulate the surgery. The mechanical female voice introduced.

"Scenario simulation, when the host obtains system binding, the operation to rescue the mutated external iliac artery rupture is a scene simulation, and the operation is completely replicated and repeated simulation training is carried out, which is suitable for patients undergoing surgery."

"Free simulation, suitable for patients who have not yet operated, through simulation to select the best surgical plan, or improve the surgical plan, you can independently choose a variety of equipment combinations to simulate surgery, not limited by real scenes."

"Idea activation?" Yang Ping asked.

The mechanical female voice replied, "You have a simulated patient and surgery in your head, and the system will provide the test subject and surgical equipment according to your ideas. ”

According to the system's guidance, Yang Ping wanted to simulate Sisi's surgery --- use focused ultrasound to kill tumor cells.

This thought clearly appeared in his mind, and an experimental subject immediately appeared in front of Yang Ping, lying on a medical device, but they were shrouded in a thick fog and blurred.

"This simulation surgery requires 50,000 credit points, are you sure about the simulation?" Prompted by a mechanical female voice.

So expensive? 50,000 points!

There is no way, if it is not simulated, I am afraid that Sisi's surgery will not be able to be done, because some defects of the focused ultrasound knife itself cannot be made up by the doctor's technology.

"Sure!" Yang Ping gritted his teeth.

The dense fog in front of him immediately dissipated, and Yang Ping took a closer look, and this medical equipment turned out to be a focused ultrasound knife, exactly the same as the one in Sanbo Hospital, and Sisi was lying on it.

"This is a replica of her, not a real patient, the technical information about the equipment, the patient's medical records and treatment, can be accessed through the light screen." The mechanical female voice finished speaking, and stopped talking.

Yang Ping was not in a hurry, first called up the manual and other information of this focused ultrasound knife from the light screen, and read it several times word by word to master the principle, structure, use, precautions and so on of this equipment.

I have studied the data in the focused ultrasound department before, and I have a certain foundation, so this research is very easy.

It seems that this system only creates conditions for itself, and as for acquiring knowledge and ability, you have to rely on your own efforts, and if you don't have enough perseverance, you can't play this system at all.

Because the system space is a closed, lonely, and isolated space, in such a space, I am afraid that few people can consciously learn.

After studying the focused ultrasound knife thoroughly, Yang Ping studied Sisi's replica again, and the medical records of the replica can be called up on the light screen, which are edited in the system space, which are more detailed than her real medical records, and can call up all her medical records from birth to the present.

Among them, the image data, whether there is an examination that has been done in reality, or whether it has been done in reality, can be found here, for example, if you want to take an X-ray of a certain part of the replica, you only need to choose X-ray. If there is something in reality, it will be called an X-film in reality; In reality, there is none, the system will take another picture of her and call it up.

This function is powerful, but it is too expensive, the local tyrant function, the local tyrant price!

Unless forced to do so, a few simulated surgeries will consume the points accumulated in a stage of the task.

The replica and equipment were almost studied, and Yang Ping began surgery to kill the tumor with focused ultrasound.

It looks like it's a very simple thing, aim at the tumor and shoot.

It can be really put into practice, but it is an extremely complex thing.

First of all, positioning is a very difficult thing, this positioning is three-dimensional positioning, not only XY coordinates, but also Z coordinates.

It's like a big gem hidden in the ground, after detection, set a point on the surface, drill a hole from this point into it, just drill to the position of the gem, not deep or shallow, and take out the gem inside.

Focused ultrasound knife bombardment of tumors, it is more difficult than such a hole to dig gems, it uses the method of beating cattle across a mountain, across a mountain, hitting the cow, can not be deviated.

After ultrasound focusing, it penetrates the skin fascia muscles and hits the tumor, if it deviates, not only can not kill the tumor, but also burns out the normal tissue.

Some people use ultrasound to make uterine fibroids, but the fibroids are not cleared and the skin of the abdomen is burned out.

Therefore, it also has side effects, and the premise is that there can be no errors, as long as there are errors, there will be the possibility of accidentally injuring normal tissues.

This instrument, the two most fatal weaknesses, one is that the positioning ability is too poor, the use of color ultrasound positioning, it is difficult to achieve accurate three-dimensional positioning, this weakness makes its power reduced.

Secondly, it cannot detect the temperature of the target organ in the body, and it cannot detect how high the temperature is after hitting it, and whether it can kill the target.

This is very troublesome, this cannon is pulled out to bombard the enemy's target, the hit rate is very low, the lethality is unknown, even if it hits, it is possible that the enemy is unscathed, and the battlefield practicality of such a cannon is very low.

This device is very well conceived, and there is still a long way to go before it can become a full-fledged medical device based on the world, at least in its current state, and it is difficult to play a big role.

But in Sisi's current situation, there is no other way to think of it, so Yang Ping tried to use this method.

Yang Ping began to perform focused ultrasound therapy on Sisi's replica, and with this function of simulated surgery, he could continue to trial and error, and accumulate data from trial and error.

Yang Ping uses the mouse of the computer to control the high-frequency ultrasonic transmitter head to carry out high-frequency ultrasonic focusing, aiming and bombardment.

The transparent human body on the light screen will immediately display the bombardment site, temperature, and error, and Yang Ping will continue to correct it according to these data prompts until it can accurately hit the tumor.

With the prompt of the light screen, Yang Ping boldly adjusted the parameters of the ultrasound to produce the best temperature and achieve good results when bombarding the tumor.

With each bombardment, not only the temperature of the target organ, but also the surrounding temperature will be displayed, so that the surrounding normal tissues will not be accidentally injured.

Yang Ping experimented little by little, and then wrote down the data of each success, only the tumor bombardment at the primary site of the right femur, from the center to the edge, Yang Ping tested thousands of times before adjusting the number of bombardments and the parameters of each time.

Immediately afterwards, he tested the metastases of the liver, and it took thousands of tests to obtain satisfactory parameters.

For metastases in the lungs, it is difficult for ultrasound to work because of the obstruction of the ribs, so Yang Ping tried to penetrate the intercostal space to achieve the purpose of treatment.

After painstaking efforts, the primary tumor of the right femur, liver, lung, and vertebrae metastases were tested one by one, data were collected, and then the data were written down.

Each tumor needs to be bombarded dozens of times, and the parameters are completely different each time. There are more than 200 bombardment data on several tumors, and Yang Ping remembers all of them in his mind.

If there is no surgical simulation function in the system space, using the focused ultrasound knife to treat the tumor for Sisi is probably just an idea and cannot be realized.

Now, through surgical simulation, Yang Ping has obtained a large amount of accurate data, which can only be obtained through trial and error, and there is no way to obtain it in reality.

Coming out of the space, Yang Ping must have grasped Sisi's tumor treatment in his heart.

It is impossible to completely cure, but ultrasound treatment can reduce the spread of tumor cells, so that the tumor and Sisi's body can maintain a temporary balance.

In this way, it is also a great success to survive with tumors and prolong the survival time.
