Chapter 640: Exploring the Limits, the Shocked Director!
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, I've been waiting for you!"
"The cutting depth device is the key to detecting the rocker arm angle and force control for the rotation angle of the rocker arm. If it can be successful, then the most basic step will be completed!"
Barton pulled Xu Qiu to the parts of the craniotomy machine. On the table was a depth-of-cut device controlled by an MCU microprocessor electrical appliance and an inverter asynchronous motor.
Its internal structure is very precise. The base, head fixation device, etc. have been removed, leaving only the core structure.
But even so, there are various sophisticated 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.
This program is also one of the core of Xu Qiu's design. It can accurately detect whether the drill bit is too close to nerves, blood vessels and other structures, thereby sending a signal to control the drill bit to stop drilling...
Of course, whether it can be applied clinically, and how big the gap between the ideal situation and actual clinical practice is, depends on this experiment.
"Let's begin." Xu Qiu was also looking forward to it.
"Okay!" Barton's eyes were bright and his expression was full of excitement.
Others in the laboratory could not hide their excitement at this moment.
Finally, after a short wait, the machine started!
Sizzling——
The depth-of-cut device drills into the simulated skull.
This is a simulated structure brought back by Barton's team from the University of Utah. The density and material of the simulated skull are almost identical to the human skull. There are also a large number of nerves and simulated blood vessels made of thin and brittle materials distributed inside.
As long as the drilling control is not precise 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 operation failed!
Sizzling——
The harsh sound resounded in the laboratory, and everyone, including Xu Qiu, held their breath and watched this scene.
After thirty seconds of waiting.
The sound of drilling suddenly stopped.
There is still no dye appearing on the top of the simulated skull, but there is a standard and perfect bone window opening on the white skull. Inside, the drill bit is just about to drill through the last layer of skull, and the blood vessels will be broken with just a few centimeters. place!
"It's...successful!" Barton's surprised voice sounded.
At the same time, the laboratory burst into enthusiastic applause.
The distribution of nerves, blood vessels, etc. inside the simulated skull is chaotic and without any rules.
In this sense, if the deep cutting device can complete the craniotomy on the simulated skull, it will be more comfortable clinically!
"The depth of cut device is complete!"
"Internal protection, inverter, and MCU microprocessing circuit, combined to perfectly control the depth of cut device, Dr. Xu's idea is not wrong!"
At this moment, everyone looked at Xu Qiu in unison, their eyes full of reverence and gratitude.
…
…
"Congratulations, master-level scientific research ability has gained proficiency +2!"
On the way back to the clinic, Xu Qiu received feedback from the system.
Barton was still chattering beside him, looking forward to the future of the craniotomy machine.
"Dr. Xu, significant progress has been made on the most difficult foundation. According to this progress, we only need to reassemble the depth-of-cut device, rocker arm equipment, etc., and we will be 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 Patton’s team was also excited.
They saw the unique advantages of the new craniotomy machine at a glance.
The unique cam design can reduce the mechanical impact of the drill bit on the skull, making it the safest and most reliable craniotomy method at present.
In addition, once the drilling of the bone area is completed, the inner drill will automatically pop up within one millimeter of advancement. Coupled with the unique anti-slip top design, bone pad protection and other details, Xu Qiu has almost achieved the ultimate improvement.
"Come on." Xu Qiu encouraged.
The remaining proficiency depends on you continuing to improve according to my design drawings.
Barton 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 the high-field magnetic resonance interventional operating room cannot be delayed.
…
It's past eleven o'clock in the morning.
While Xu Qiu was still in the outpatient clinic, Director Lin of the Brain Surgery Department came to inform him that the Director of the Brain Surgery Department of Greentown No. 1 Hospital was here.
"So fast?" He was a little surprised.
Xu Qiu continued: "Director Lin, you show him around first, and I will go there after the consultation."
Director Lin quickly agreed.
At 12:30 noon, as soon as Xu Qiu came out of the outpatient clinic, he bumped into the director of the brain surgery department of Greentown No. 1 Hospital who had been waiting outside.
"Director Lu."
"Dr. Xu, you're finally off work. I can't wait any longer!" Director Lu of Greentown No. 1 Hospital rubbed his hands with a smile on his face.
Fifty million, that’s a saving of fifty million!
"I'll have a meal first." Xu Qiu said calmly.
It's not something serious like seeing a doctor, so we can't delay lunch.
Director Lu gritted his teeth. He was extremely anxious, but he had to let people eat.
By the time 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 written last night in front of him.
"That's it?" Director Lu was a little surprised.
He thought it was scratch paper.
"Yes, that's all." Xu Qiu said.
Director Lu flipped through the pages doubtfully, and slowly, his expression became more and more solemn, and then covered with ecstasy.
Bang!
Director Lu slapped the table excitedly, his face full of excitement: "Is it... feasible?"
"Totally feasible."
"How could it be, how do you know it's feasible! Linhai First Hospital doesn't have a high-field magnetic resonance intervention operating room, and you haven't seen the real role of the composite operating room, how can you be so sure!"
Xu Qiu smiled.
The role of the simulated operating room is many, and it is easy to simulate a high-field magnetic resonance intervention operating room. Naturally, he has tried it many times in his mind, and only after getting a positive conclusion did he dare to give the 50 million statement.
Director Lu is still in shock.
"Our high-field magnetic resonance interventional operating room actually requires more than just neurosurgery. In addition to this department, we also need the cooperation of the procurement department, medical department, logistics department, anesthesia department, interventional department, infection office, intraoperative magnetic resonance imaging department, and nursing department. Only when doctors from seven or eight departments work together can we have a certain degree of certainty...
"Moreover, after surgery, patients often need additional interventional treatment. This is also the reason why surgery requires interventional doctors..."
Director Lu swallowed his saliva, his pupils filled with disbelief.
However, now, Xu Qiu's plan has overturned all of this.
He used an extremely bold method to tap the potential of the operating room and the application of equipment to the theoretical limit!
