Rapid development of artificial intelligence, medical robots bring well-being

Recently, a British teenager named Billy Whitaker underwent surgery to get rid of the pain of epilepsy that lasted for seven years. Doctors let the robot drill into his brain, stimulate the cerebral cortex through electrodes, find the part that causes the seizure, and the doctor removes the lesion. The procedure, known as stereotaxic EEG, has been successful. Not only that, but robots can also flex their muscles in other types of surgery. A 'surgeon' robot must know 'what to do' and be able to plan 'how to do it'. This requires an efficient and stable microelectronic system - including the hardware and software environment (brain), sensors (eyes) and electromechanical devices (hands). The 'brain' works similarly to a home desktop computer. However, medical robots are often developed based on open source operating systems such as Unix or Linux to ensure software stability. 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 rampage in the human body. This design requirement of low power consumption and high stability happens to be the same as that of mobile electronic devices. The development of mobile electronic devices in recent years has provided invaluable experience for medical robots. The 'eyes' of robots usually refer to all physical and chemical sensing instruments, and the more common ones are pressure sensors, video acquisition devices, and solution component detection units. The 'eyes' collect information and transmit it to the 'brainIt is generally made of high-polymer plastic, which is resistant to acid and alkali, and is not easy to leave toxic substances in the body. It can achieve very high manipulation accuracy and complete precise surgical tasks. In this system, artificial intelligence plays an important role. It can assist doctors to improve medical plans, and automatically take emergency measures to reduce risks when encountering unexpected problems. At present, the most commonly used medical robot on the market is the 'Da Vinci' system. The doctor simply sits in front of the monitor, manipulates the joystick, and completes the procedure. Its biggest feature is 'scaling'. The surgeon can adjust the scaling ratio and change the scale ratio of manual manipulation and actual movement, so as to achieve ultra-fine surgery and improve the success rate of surgery. The fly in the ointment is that a patient needs to pay for expensive equipment for this procedure. The advantages of medical robots are self-evident. Even the best surgeons cannot guarantee the complete stability of the surgical instruments due to the rhythmic pulsation of the blood vessels in the hands with the heartbeat, 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 only needs a 2 cm incision, and can even be taken orally into the human body, which greatly reduces the risk of postoperative infection and speeds up postoperative healing time. In addition, the medical robot can also be operated remotely. As long as the doctor is connected to the network, the surgeon can remotely operate the robot to complete the operation without meeting the patient, which greatly reduces the time cost of the doctor and the patient. In fact, in addition to 'surgery doctors ot, and will bring great benefits to mankind.
