Chapter 586 Semi-automatic Surgical Robot
"A semi-automatic multifunctional surgical robot?"

"Able to perform fine surgery in the four major fields of orthopedics, laparoscopy, neurosurgery, and vascular intervention?"

Wei Kang was completely stunned after reading the beginning.

There is no other, but because the surgical robots currently on the market are all special-purpose robots, and they all perform surgical operations in a specific department. For example, the Da Vinci robot is the king of laparoscopic surgery.

In addition, orthopedics has dedicated surgical robots, neurosurgery also has specialized spine surgery robots, and even ophthalmology has specialized ophthalmic surgery robots.

The so-called all-round surgical robots have not yet appeared, and they all do their own things.

Because the treatment plans in different fields are different, it is difficult to make one universal.

He originally thought that it would be enough for the robot provided by the system to defeat Da Vinci in laparoscopic surgery.

Unexpectedly, the system directly gave him a bomb.

No wonder it takes 5000 million points, it's worth it!It's so worth it!

Wei Kang's heart suddenly became hot, and he couldn't wait to look down.

"What kind of semi-automatic? What kind of multi-function?"

"It turns out that the nine functions of automatic detection, automatic positioning, automatic navigation, automatic tracking, automatic imaging, automatic simulation, automatic cutting, automatic filtering, and automatic stitching can all be realized through voice control, manual and other human-computer interaction."

"Automatic detection can monitor the patient's vital parameters and function as a monitor. At the same time, through advanced sensing technology, it can obtain a series of operations during the operation and automatically form relevant data."

"Automatic positioning is easy to understand. An important requirement of laparoscopic robots is the automatic positioning of endoscopes, which saves the need for operators who need to hold endoscopes in routine operations and can obtain more stable images.

"With automatic positioning, there will naturally be related functions such as automatic navigation, automatic tracking, and automatic adjustment."

"Automatic imaging is also very important. The magnified 30 times high-definition 3D image can not only show the surgical field of view, but also facilitate accurate tissue positioning and instrument operation for doctors."

"Automatic simulation is to use the patient's test data and medical images to simulate the surgical process before surgery through virtual reality technology."

"Automatic tremor filtering is indispensable in terms of safety. It can filter out hand tremor movements during microsurgery, filter out natural tremors of human hands, improve surgical accuracy, and prevent accidental movements."

"Automatic cutting uses an ultrasonic scalpel to precisely cut patient tissue and orthopedic implants, enabling better surgical outcomes."

"Automatic suturing can perfectly suture soft tissues such as skin, muscle, blood vessels and nerves."

"My God, isn't this the ultimate form of surgery?"

"All auxiliary work is completely done by an automatic control robot controlled by a set of medical procedures, and the surgeon only needs to devote himself to the operation."

"In the future, only one surgeon will be needed for surgical operations, and no other personnel will be needed."

"The first and second aids of the retractors, and the nurses who deliver the equipment are all gone."

After the excitement, Wei Kang couldn't help but wiped off his cold sweat, feeling a little shuddering.

"Will I really not be beaten?"

"If this goes on, appendectomy can be done by surgical robots in the future."

"Do you still need so many medical staff?"

"Bad news, layoffs of medical staff!"

"The good news is that it's faster and easier for doctors to learn to operate."

"In the future, surgeons can cooperate with robots to complete more complex operations, and more powerful doctors will directly research and develop new surgical methods."

Thinking of this, he felt a little better.

This is okay, it seems that it will not become a public enemy of medical care.

"Automatically completing simple operations and auxiliary functions can indeed be called semi-automation."

"Fortunately, it's not yet fully automated, and it can directly replace human doctors. Otherwise, I would never dare to launch it, so I can only put it on the shelf."

"Look at the multi-function again."

Wei Kang breathed a sigh of relief and continued to look down.

"Any surgical robot cannot escape the three major components of the brain, hand, and eye. The optical tracking system is the eye, which completes the preoperative scan and closely tracks the patient and surgical tools during the operation. As for the multifunctional robotic arm, it is the hand to achieve precision. Surgical positioning navigation and operation, and then as the master console of the brain."

"The doctor sits in front of the main console far away from the aseptic area of ​​the operation, looks at the high-definition screen showing the 3D image of the internal structure of the body, and simultaneously holds two control handles up and down, left and right, and rotates back and forth. At the same time, through the built-in microphone, the auxiliary function is mobilized by voice. Switching non-stop surgical tools, only one person is needed to complete a surgical operation independently."

"Compared with the bloody scenes of traditional open surgery, there is almost no bleeding in robotic surgery. Some suction, suturing, and cutting operations are also performed by robots, which greatly liberates doctors' productivity."

"Needless to say the brain function of the main console, intelligent surgical tracking, adjustment, and positioning are trivial matters."

"The biggest surprise is that there is a standard operation mode and operation memory function for each individual operation."

"Each doctor can open an account separately, record every action during his operation, and then choose the smoothest and most successful operation mode to save it. When the next operation is performed, the robot can automatically adjust to this mode, which perfectly cooperates with the doctor to complete the same operation. surgery."

"At the same time, these standard models can also be used to assist doctors in learning new operations, which not only greatly improves learning efficiency, but also reminds them in time if they make mistakes in practice, so that they can be corrected to the right track."

"It's awesome. The threshold for first- and second-level simple operations has been lowered to the level of medical operators. In the future, mass production of low-level doctors should not be a big problem."

"Okay, the brain is awesome, let's see if the eyes are just as awesome."

"Sure enough, it's awesome!"

"Advanced optical and infrared vision imaging technology, high-performance imaging system, realistic 3D display effect, the surgical image is magnified 15-30 times, fully providing a real surgical field of view."

"All medical imaging data is converted into a real color 3D model by computer, and the surgeon can manipulate the robotic arm to cut in at a 360-degree angle, just like being there personally, to complete the most difficult operation."

"Okay, okay, okay, doing this is the real surgical weapon."

Wei Kang couldn't help applauding.

Although he is not a surgeon, he also knows that the surgical field of view has a major impact on surgical operations.

The poor surgical field of view is like a blind man feeling an elephant for a surgeon. Not only is it difficult to complete the operation smoothly, but the risk of the operation will also increase greatly.

In traditional open surgery, doctors have the habit of operating under direct vision, and can complete the operation through intuitive hand-eye coordination. The coordination of both hands makes the operation very dexterous.

But after laparoscopic surgery became popular, it broke this natural hand-eye coordination of the human body.

Doctors can't see the patient's tissue and can only watch two-dimensional video to get the surgical view.

While watching, move the laparoscopic surgical tools with one hand.

This kind of operation is quite anti-human, and it also violates human intuition.

After all, from the moment of birth, everyone has to complete various actions through hand-eye coordination.

Moreover, human vision is three-dimensional, and after decades of living habits, it is not so easy to break.

In addition, the display of laparoscopic equipment is opposite to the actual direction of movement, which is difficult to adapt to at first.

It's like getting used to the mouse scrolling of the win computer, it is difficult to use the mouse of the fruit computer.

These operations, which are contrary to common sense, will bring trouble to doctors.

It's hard to learn, and it's artificially difficult to use.

Not to mention the magnification of the physiological shaking of the doctor's hands by the long rod-shaped surgical instruments.

Therefore, although laparoscopic surgery greatly reduces surgical trauma and is conducive to postoperative recovery of patients, it is much more difficult for doctors than open surgery.

From normal mode to hard mode.

This has also led to a certain threshold for laparoscopic surgery, and it takes a lot of time and energy to train skilled doctors.

In short, it is killing doctors and benefiting patients.

Surgical robots are completely different.

Not only is the surgical field of view 3D imaging, it is more similar to an open surgical scene.

The doctor's operation is also done through dual handles, and the sense of direction is consistent with the real world.

The difference is naturally made up by the powerful computing power of the main console and the 360-degree flexible movement of the mechanical arm without dead ends.

As long as the doctor sits comfortably in front of the main console, he will have a wide field of vision, move his hands flexibly in a small area, speak keywords, call out different surgical tools and auxiliary equipment, and can smoothly complete a surgery , Even if you sit for a few hours, you will not feel tired.

It is equivalent to jumping directly from the difficult mode to the easy mode.

This kind of technological development not only benefits patients, but also benefits doctors, which can be described as a win-win situation.

"Tsk tsk, it's really suitable for my wife. Even if she is weak after giving birth, it won't delay her surgery."

Wei Kang thought happily, and couldn't help showing an excited smile on his face.

However, he did not indulge in his imagination, but looked at the design drawings of the robot with fiery eyes.

"This is the most critical part of the robot."

"Almighty robotic arm!"

"It turns out that specialized surgeries in different fields are performed by these different robotic arms."

On the densely packed drawings, there are five independent robotic arms on the huge base of the surgical robot.

Each robotic arm has a distal rotation center structure to ensure that the surgical instrument runs around a fixed skin entry point during motion.

Among the five robotic arms, four are dedicated to orthopedics, laparoscopy, neurosurgery, and vascular interventional surgery, and one is an auxiliary robotic arm.

Each robotic arm is very flexible and has multiple retractable functional arms at the same time, just like a Swiss army knife.

The biggest feature of the single-hole endoscopic surgical arm is that after a mechanical arm enters the body through a single hole, it automatically expands into three continuous operating arms and a 3D high-definition camera, which can achieve visibility in a narrow surgical space control.

The orthopedic robotic arm is relatively small and can be positioned according to the patient's anatomical structure, and assists the doctor to complete accurate bone cutting operations through force feedback.

For complex spinal surgery, the functional arm can be directly installed on the patient's spine to achieve a rigid connection, accurately perform navigation operations, and guide doctors to complete the placement of pedicle screws.

After the neurosurgery arm is deployed, there are also 3 functional arms. The two arms can perform various intracranial operations, assist the doctor to accurately send the puncture needle, electrodes and other instruments to the predetermined target, and flexibly complete biopsy, foreign body removal, and cyst suction. and so on.

The third functional arm is equipped with a surgical microscope to support microsurgical operations.

The vascular interventional operation arm is also composed of two functional arms. A multi-joint functional arm is loaded with a disposable manipulation box, which can pull and manipulate the catheter system, control the bending of the catheter and the movement of the guide wire, and can also be loaded with stents and balloons. and other related equipment.

A magnetic navigation system is installed on the other functional arm, which can use an external magnetic field to drive the movement of the guide wire, thus avoiding the radiation problems caused by X-rays.

For the complex anatomical environment of the heart, the fusion of the magnetic navigation system and the 3D imaging system can locate the tip of the guide wire, and transmit its position, direction data, target point, and anatomical geometry information to the main control system, thus eliminating the need for X-ray imaging and The position of the catheter can be monitored in real time.

As for the auxiliary robotic arm, it is specially designed for microvascular suture surgery, with force detection function, and can complete surgical operations such as cutting, clamping, suturing and knotting.

A force sensor is installed at its end, which can detect the force information between it and the surgical environment, and feed back the force information to other surgical arms, so that the surgeon can feel the three-dimensional force information of the surgical environment more intuitively and improve the safety of the operation.

Other surgical tools can also be delivered to perform some auxiliary functions.

Each robotic arm adopts a articulated structure and has a three-dimensional force sensing function. Without exception, they all have extremely flexible simulated wrists that can move freely in 8 directions and rotate 360 ​​degrees, completing operations that cannot be achieved by human hands.

The accuracy of surgical positioning has also reached the sub-millimeter level.

It also has a motion scaling function, which not only ensures the accuracy of the operation, but also minimizes the natural shaking of the doctor's hand or unintentional movement.

In short, advanced sensing technology, 3D medical imaging technology, new materials, and intelligent algorithms enable the end of the surgical robot to be designed to be more flexible than the human hand, and can scale the operator's movement to bring the operator closer to the tip of the surgical instrument. More contacts, to achieve a variety of surgical operations.

Finally, all robotic arms can be flexibly installed and removed according to surgical needs.

Only one surgical robot arm and auxiliary function arm can be installed to complete a single operation, or two surgical robot arms can be installed to complete multiple operations at the same time.

It can also hold tools according to the needs of clinicians to perform operations and treatments.

For example, it is applied to bone cutting when installing joint prosthesis, fine operation in microsurgery, endoscopic operation in minimally invasive surgery, moving linear accelerator in radiation therapy, etc.

Seeing all this, Wei Kang was very excited, as if the door of a golden treasure house was slowly opening in front of him, waiting for his entry.

"Great! With such a surgical robot, there will be no more difficult operations in the world."

"Whether it is traditional open surgery or laparoscopic surgery, the advantages of surgical robots are obvious."

"Like any robot, its biggest advantage is that it will not tire no matter how long it works, while maintaining a high degree of precision."

"Its accuracy in one use is the same as that in the first use, without the slightest deviation."

"And the limitation of human ability is the bottleneck that has existed in clinical surgery for a long time."

"Especially the unavoidable trembling of human hands and the fatigue of doctors, which makes it difficult to guarantee the accuracy of surgery."

"Not to mention the narrow surgical field of view and limited operating space of minimally invasive surgery, which undoubtedly greatly increases the difficulty of surgery."

"But these problems are almost non-existent with surgical robots."

"The training of a qualified doctor is very long and requires repeated failures, which leads to high costs."

"Surgical robots can greatly shorten the maturity time of a qualified doctor and greatly reduce the difficulty of learning, thus providing a balanced and stable medical quality."

"Robots can quickly improve the clinical level of junior doctors to the same level as senior doctors, and solve the problem of high-quality medical data that is too concentrated, unevenly distributed, and in short supply for a long time."

"My dream has taken another solid step towards its realization."
