Exploration of surgical robots around the world began in the 1980s. In 1985, American researchers tried to use an industrial robot to assist brain tissue biopsy, which is also the embryonic form of surgical robots. In the late 1980s and early 1990s, surgical machines dedicated to surgery were born. The most representative one is the RoboDoc surgical robot. In 1994, Aesop's robots with mirrors developed by Computer Motion of the United States achieved a more precise and consistent lens movement than humans. It took a key step in the development of robotic minimally invasive surgical systems, but it cannot execute instructions alone. Surgical operation is only a "fuji" electronic manipulator. In 1996, Computer Motion developed the Zeus robotic surgical system to try minimally invasive surgery. In 1999, the United States Intuitive Surgical Corporation released the Da Vinci surgical robot, which opened a new era for the development and application of surgical robots. The Leonardo da Vinci surgical robot consists of a surgeon console, a bedside robotic arm system, and an imaging system. Compared with the human hand, its simulation wrist device has 7 degrees of freedom, more flexible, accurate, and can automatically filter out tremor, more stable than the human hand. In addition, its imaging technology is more realistic, and the naked-eye 3D stereo high-definition image can enlarge the image 10 times. Since its release, Da Vinci's surgical robots have been out of control and have been rapidly applied throughout the world, virtually monopolizing the global surgical robot market and continuing to this day. In 2000, the Da Vinci surgical robot was officially approved for use by the US Food and Drug Administration and became the first surgical robot to be used in abdominal surgery. 301 Hospital introduced the first Da Vinci surgical robot in mainland China at the end of 2006, and completed the first operation in 2007. In 2014, Da Vinci Surgical Robot updated its fourth-generation system. In Du Zhijiang's view, Da Vinci's surgical robot has been able to occupy the first place, and its attention to the close integration of engineering technology and medical needs has contributed. “When I visited Intuitive Surgical, I saw that one of the company’s engineering technicians’ day-to-day work is to fully communicate with doctors so that the robot can best meet the needs of doctors.†Du Zhijiang concluded, “Da Vinci Surgical Robot There are multiple robotic arms that perform the surgery in a multi-arm coordinated manner; it relaxes the requirements for the position of the human incision. During the operation, the robotic arm must enter through the incision of the human body. If the incision requirement is too strict, some surgical procedures are required. It is not easy to operate; in addition, the Da Vinci surgical robot is easy and quick to set up, reducing the preparation time for surgery, especially when accidents occur during the surgery to switch from minimally invasive surgery to open surgery, it is necessary to put the surgical robot The instruments were removed in a very short time; the interface of Da Vinci's surgical robots was unified, reducing the time needed for surgical replacement of instruments; in addition, it can be pre-programmed on a proactive basis to continuously improve the intelligence level of robots. The research and development of the Finch surgical robot has been moving forward in these directions." In the 1990s, domestic research began on the use of surgical robots. Typical systems such as brain surgery robots jointly developed by Beijing University of Aeronautics and Astronautics and Navy General Hospital and orthopaedic surgical robots developed by Beijing University of Aeronautics and Astronautics have all been certified by the State Food and Drug Administration. In addition, Harbin Institute of Technology conducts research in the fields of laparoscopy, orthopedics, and interventional surgery. The Institute of Automation of the Chinese Academy of Sciences conducts research in areas such as vascular interventions and orthopedics, and Tianjin University conducts research in the fields of laparoscopy and microsurgery, etc. The University of Science and Technology conducts research in the fields of soft tissue puncture, craniomaxillofacial surgery, etc. Fudan University and Zhejiang University have also conducted research on medical robots and achieved results. Du Zhijiang believes that in order to do a good job in the research and development of surgical robots, we must first pay attention to the integration of medical workers. "Doctors should clearly explain the surgical operation procedures, the use of surgical robots, and taboos on medical applications, and they can put forward some subjective content. The engineers and technicians need to listen, understand, determine the design input, and plan the implementation, and then use The language of engineering language is expressed, after taking out the prototype, it is repeatedly communicated with the doctor. Doctors and engineering technicians must interact. This interaction may be long-term.†To Du Zhijiang, the current development of medical robots has good prospects. At present, the global market for medical robots continues to grow at a rapid rate. Several strategic plans and support policies have been successively introduced in China to promote the healthy and rapid development of the robotics industry, including “Made in China 2025†and “Robot Industry Development Plan (2016-2020). "And so on, where the medical robot is an important part. "As a kind of robot, surgical robots have unlimited room for innovation in such areas as organization, sensing, control, interaction, and the Internet," Du Zhijiang said. At the same time, the development of surgical robots also faces challenges from technology, talent, capital, markets, and policies. “Surgical robots are highly technically intensive robotic systems with high technical barriers and require talents in robots, medical devices, and medicine, especially cross-border composite talents. The research and development cycle of surgical robots is also relatively long, generally 6 to 6 In 10 years, the investment is large, the risk is high, and continuous investment is needed.†Du Zhijiang said, “If we want to make outstanding progress in the field of surgical robot R&D, we must establish a long-term mechanism that integrates 'political-producing-study-research-medical'. , Form the government guidance, capital support, corporate efforts, R & D team to fight gas, doctors dare to try the situation, open up the R & D, registration, production, sales chain. It also requires a lot of joint efforts."
Residual Current Circuit Breaker
RCCB named Residual Current Circuit Breaker. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, Residual current circuit breaker/RCCB(without over-current protection) will cut off the power rapidly to protect human safety and prevent the accident due to the current leakage. The rccb switch which made from Korlen electric can be used as infrequent changeover of the line in normal situation.
Korlen electric ---- the rccb switch manufacturer,produces types of Residual Current Circuit Breaker. It is applicable to industrial site, commercial site, tall building and civil house.
