Robots can not only be "professional players" but also "surgeon doctors".
Recently, a British teenager named Billy Whitaker underwent surgery to get rid of 7 years of epilepsy. The doctor asked the robot to drill into his brain, stimulate the cerebral cortex through the electrodes, and find out what caused the seizure. The doctor removed the lesion. This surgery is called stereotactic EEG, and there have been successful cases.
Not only that, but robots can also make a big difference in other types of surgery. A "surgical doctor" robot must know "what to do" and can plan "how to do it." This requires an efficient and stable microelectronic system – including hardware and software environments (brains), sensors (eyes), and electromechanical devices (hands).
"Brain" works like a home desktop computer. However, medical robots are often developed based on open source operating systems such as Unix or Linux to ensure the stability of the software. At the same time, the power of the central processing unit of the medical robot will not be very large, otherwise it will have to be equipped with a fan and a power cord to ram across the human body. This low-power, high-stability design demand happens to be the same as mobile electronic devices. The development of mobile electronic devices in recent years has provided invaluable experience for medical robots.
The "eye" of a robot usually refers to all physical and chemical sensing instruments. The most common ones are pressure sensors, video acquisition devices, and solution component detection units. The "eyes" collect information, pass it to the "brain", the "brain" makes decisions, and the ultimate implementer of decision-making is the "hand." It is generally made of high-poly plastic, which is resistant to acid and alkali, and is not easy to leave toxic substances in the body, and can achieve very high manipulation precision and complete precise surgical tasks. In this system, artificial intelligence plays an important role in assisting doctors to improve their medical plans and automatically take emergency measures to reduce risks in the event of unexpected problems.
The medical robot currently in use on the market is the "Da Vinci" system. The doctor simply sits in front of the display and manipulates the joystick to complete the operation. Its biggest feature is "zoom", the surgeon can adjust the scaling ratio, change the scale ratio of manual manipulation and actual movement, thus achieving ultra-fine surgery and improving the success rate of surgery. The fly in the ointment is that a patient needs to pay for expensive equipment for this type of surgery.
The advantages of medical robots are self-evident. Even the best surgeons, because of the rhythmic vibrations of the blood vessels in the hands, cannot guarantee the complete stability of the surgical instruments, and this disadvantage is compensated by the high-precision electromechanical structure of the medical robot. Medical robots are also minimally invasive. A small electromechanical device often requires only 2 cm of wounds, and can even enter the human body after oral administration, thus greatly reducing the risk of postoperative infection and accelerating the time of postoperative healing. In addition, the medical robot can be operated remotely. As long as the network is connected, the surgeon can remotely operate the robot to complete the operation without having to meet the patient, greatly reducing the time cost of the doctor and the patient.
In fact, in addition to "surgery doctors", more and more supernatural robots are constantly coming out, such as robot chefs, such as artificial intelligence creative directors... With the rapid development and widespread application of artificial intelligence technology, in the future, robots may have nowhere. No, and will bring great benefits to mankind.
