Four o'clock in the morning.

Linhai University School of Medicine, third floor of the laboratory.

As soon as Xu Qiu came in, countless eyes gathered at the same time.

"Doctor Xu!"

"You're finally here, waiting for you!"

"The depth cutting device is the key to detecting the rotation angle of the rocker arm and the force control of the force. If it can be done, the most basic step will be completed!"

Patton pulled Xu Qiu to the side of the craniotomy machine, and a depth cutting device controlled by the mcu microprocessor appliance and the inverter asynchronous motor were placed on the table.

Its internal structure is very precise, with the base, head fixing device, etc. removed, leaving only the core structure behind.

But even so, there are various precision data processing control devices and depth sounding detectors.

Of course, the most important thing is actually the built-in protection program in the drill bit part.

This program is also one of the core designs of Xu Qiu. It can accurately detect whether the drill bit is too close to the nerves, blood vessels and other structures, thereby sending a signal and controlling the drill bit to stop drilling...

Of course, whether it can be applied to clinical practice and how big the difference between the ideal situation and the actual clinical practice is this experiment.

"Let's start." Xu Qiu was also looking forward to it.

"Okay!" Patton's eyes lit up and his expression was full of excitement.

The rest of the laboratory could not hide their excitement at this moment.

Finally, after a brief wait, the machine started!

Sizzy—

The depth cutting device drills onto the simulated skull.

This is the simulated structure brought back by Patton's team from the University of Utah. The density and material of the simulated skull are almost exactly the same as that of the human skull. There are also a large number of nerves and realistic blood vessels made of thin and crisp materials.

As long as the drilling control is not accurate enough, the sharp drill bit will pierce the nerves and blood vessels. In an instant, the entire simulated skull will be covered with conspicuous red and yellow dyes.

That would mean the surgery failed!

Sizzy—

A harsh voice resounded throughout the laboratory, and everyone, including Xu Qiu, held their breath and watched the scene.

After thirty seconds of waiting.

The drilling sound suddenly stopped.

There is still no dye above the simulated skull, but there is a standard on the white skull, perfect bone window opening, and inside, the drill bit stops just where the last layer of skull is about to drill through, and the blood vessels will be broken in just a slight difference! ωωw..net

"It's done...it's successful!" Patton's surprise voice rang.

At the same time, the laboratory burst into warm applause.

The distribution of nerves, blood vessels and other internal distributions in the simulated skull are messy and have no rules.

In this sense, if the depth cutting device can complete the craniotomy on the simulated skull, it will be more convenient in clinical practice!

“The depth cutting device is completed!”

"Internal protection, inverter, and MCU microprocessing circuits, combined to perfectly control the depth cutting device. Dr. Xu's idea is not wrong!"

At this moment, everyone looked at Xu Qiu at the same time, their eyes full of respect and gratitude.

...

...

"Congratulations, the master-level scientific research ability has achieved proficiency level 2!"

On the way back to Linyu, Xu Qiu received systematic feedback.

Patton was still chattering around, looking forward to the future of the craniotomy.

"Doctor Xu, the most difficult foundation has made significant progress. At this progress, you only need to recombinate the depth cutting device, rocker arm equipment, etc., and you can get it done!

"According to our predictions, the efficiency of the new craniotomy machine is at least four to eight times higher than before!"

The rest of the Patton team were also very excited.

They could see the unique advantages of the new craniotomy machine at a glance.

The unique cam design can reduce the mechanical effect of the drill bit on the skull, and is currently the safest and most reliable method of craniotomy.

In addition, once the drilling hole in the bone area is completed, the internal drilling will automatically pop out within one millimeter. In addition, the unique anti-slip top design, bone pad protection and other details, Xu Qiu almost made the improvement to the extreme.

"Come on." Xu Qiu encouraged.

The remaining proficiency depends on you to continue to improve according to my design drawings.

Patton nodded solemnly: "Don't worry, within two weeks, I will definitely come up with a complete new craniotomy machine!"

Xu Qiu smiled.

It seems that high-field and strong magnetic resonance interventional operation room cannot be delayed.

...

It was past 11:00 am.

When Xu Qiu was still in the outpatient clinic, Director Lin of the Department of Brain Surgery came to inform him that the director of the Department of Brain Surgery of Greentown First Hospital was here.

"So fast?" He was a little surprised.

Xu Qiu continued: "Director Lin, take him around first, I will go there after the treatment."

Director Lin quickly agreed.

At 12:30 noon, Xu Qiu had just come out of the outpatient department and ran into the director of the Department of Brain Surgery of Greentown First Hospital who had been waiting outside.

"Director Lü."

"Doctor Xu, you're off work, I can't wait!" Director Lu of Greentown First Hospital rubbed his hands, and his face was filled with grips.

Fifty million, that would save 50 million!

"I'll have some meal first." Xu Qiu said slowly.

It’s not a serious thing like seeing a doctor, so you can’t delay lunch.

Director Lu gritted his teeth and said that he was extremely anxious, but he had to let someone eat.

When Xu Qiu finished eating, Director Lu's eyes were almost on fire.

At this time, Xu Qiu invited Director Lu to the office and placed the plan he wrote last night in front of him.

"That's all?" Director Lu was a little surprised.

He thought it was draft paper.

"Yes, that's all." Xu Qiu said.

Director Lu looked through suspiciously. Slowly, his expression became more and more serious, and then he was covered with ecstasy.

Bang!

Director Lu slapped the table excitedly, his face full of excitement: "Can...be feasible?"

“It’s totally feasible.”

"How could it be? How could you know it is feasible! Linhai First Hospital does not have a high-field and strong magnetic resonance interventional operating room, and you have never seen the real function of a composite operating room. How could it be so sure!"

Xu Qiu smiled.

There are many functions in simulating an operating room. It is easy to simulate a high-field and strong magnetic resonance interventional operating room. Naturally, he has made many attempts in his mind. Only after he reached a positive conclusion did he dare to give a statement of 50 million.

Director Lu was still shocked.

"Our high-field, strong magnetic resonance interventional operating room actually requires not only the brain surgery department. In addition to the department, it also needs the procurement and supply department, medical department, logistics department, anesthesia department, interventional department, infection office, intraoperative magnetic resonance imaging department, nursing department, etc. to work together to achieve a certain degree of confidence...

"And, after the operation, patients often need additional interventional treatment. This is also the reason why the surgery requires an interventional doctor..."

Director Lu swallowed his saliva, his pupils filled with disbelief.

However, now, Xu Qiu's plan has subverted all this.
Chapter completed!
