Playing "The Lancet" Domestic medical robot is going to clinical

Medicine Network August 8th, "Da Vinci" is not the ancestor of surgical robots"The first robotic-assisted surgery was performed in 1985, when industrial robots were used to stabilize the patient's head, making it easy for neurosurgery to drill holes and insert tissue sampling needles into designated locationsTan Min, a researcher at the National Key Laboratory for Complex Systems Management and Control at the Institute of Automation of the Chinese Academy of Sciences, introduced the progress of robotics researchlike "Alpha Dog" led the Development of the AI industry, "Da Vinci" people recognized the robot-assisted surgery, and greatly contributed to the development of the medical and rehabilitation robot industryrecently, a research report shows that the application of intelligent medical robots is becoming more and more widely used, and has become a hot topic in the medical industryThe global smart medical robot market continues to grow at a high rate, covering medical surgery, rehabilitation
sports, medical assistance and medical logisticsPreviously, experts have introduced that, at present, the share of foreign medical robots is gradually decreasing, China's medical robots are entering the marketvascular intervention robot has been practiced on the keen touch
known robot is heavy, how to make these steel guys can afford to carry the "big bag", and play "the Lancet"? On this "cross-border" road, keen perception, real-time signals, optimized processing can not be lessdifferent from the functions of the Da Vinci robot, another robot needs a keener sense of touch to prepare for the rigours of another scenarioVasculars are complex networks all over the body and in various forms, and vascular intervention robots are able to walk through the blood vessels and assist the doctor to complete the vascular intervention surgery, practicing a well-deserved sharp skillvascular intervention surgery needs to be performed in a specialized catheter chamberBecause X-ray imaging is required to operate catheters, wire guide and other interventional devices, in the past doctors in the course of surgery must wear a heavy lead clothingDuring the operation, the angle, the patient's position and the injection of contrast agent softened frequently during the operation, the operation time is long Long-term work in the catheter room is also prone to spinal disease, cataracts and even cancer occupational diseases dangerous places for robots to take their place At present, many countries have developed catheter intervention surgery auxiliary robot, the typical function is for coronary artery stenosis, auxiliary doctor delivery catheter, wire, stent and other intervention devices through the blood vessels, every millimeter of the journey must be micron not bad: through the aorta, it must pass quickly to reduce the use of X-rays and contrast agents After the narrow lesion site, high-precision operation is required to enable the guide wire or catheter to pass through the narrow lesions high precision, speed, strategy in the robot "cultivation" process can not be less "In vascular intervention surgery, when the doctor's finger is stoic, the angle of the finger joint and the position and position of the hand when pushing the guide wire are the key factors that affect the success of the operation "For this reason, the research team, using fiber-optic data gloves, proposed a method of finger flex angle recognition by analyzing the motion patterns of human bones and finger joints, and established a mapping relationship between finger flexangle angle and data glove output, said Feng Zhenball, a researcher at the National Key Laboratory for Complex Systems Management and Control of the Institute of Automation of the Chinese Academy of Sciences
"Based on this method, we solved the problem that the usefulness of the data glove output is not clear, carried out the flexangle angle experiment and verified the validity of the method Traditional data gloves are also modified by introducing electromagnetic tracking sensors This will compensate for the current vascular intervention robot lack of tactile feedback or not enough fine-looking defects, so that doctors in the robot's operating end has a real fine sense of touch the rapid growth of the rehabilitation robot market
research data show that the global medical robot market size is expected to expand from 4.9 billion U.S dollars in 2016 to 21.1% compound annual growth rate of 12.8 billion U.S dollars in 2021, of which the largest surgical robot and the fastest growth rate of rehabilitation robots if the surgical robot is a "good way to play the Lancet", then the rehabilitation robot is the "heart-to-heart" who will "hang the pulse of the consultation"
"The patient's motor intentions and actual motor abilities need to be taken into account Peng Liang, an associate researcher in the National Key Laboratory for Complex System Management and Control at the Institute of Automation of the Chinese Academy of Sciences, said that in order to complete the "interaction" between machines and humans, the data can be "virtually" contracted into muscle rhythmby by frequency oscillator, and the rehabilitation robot can assist patients in performing exercise training by means of a surface muscle electrical signal that reflects the patient's motor intentions rehabilitation robot can read myoelectric data, how does the patient's electrocardiogram signal correspond to continuous movement or force/torque? This is the key to the rehabilitation robot's ability to "hang the silk line", so it is necessary to build a dynamic model between the two At the recent China Medical Robot Cuihu Forum, Zhao Jun, Director of Neurology at the China Rehabilitation Research Center, introduced the research work on paraplegia gait kinematics and kinetics analysis and the design of rehabilitation training actions He said that in order to transfer clinical experience to robots, clinical work needs to be "data-based", such as combining advanced motion capture, foot pressure and surface electromyography technology, from joint kinematic data, dynamic data, muscle activity and other aspects of stroke paraplegia patients to carry out more comprehensive and detailed gait analysis, according to the results of the results of the design of more scientific and targeted rehabilitation training actions
"Why does a rehabilitation robot medical work like this, so not, need in-depth theoretical basis and mechanism research, the basis comes from clinical." "The Chinese Academy of Sciences Automation Institute Deputy Director Of war Chao said that the rehabilitation robot needs to be integrated with clinical research, not only hospital and the Institute of "hospital joint", under the guidance of theoretical basis, in order to produce can withstand patients and market testing of the robot from the laboratory to the clinical expectation of "one foot" the success of the "Da Vinci" robot in part thanks to its FDA approval to enter the clinic, currently in use of more than 4,000 units worldwide For medical devices, getting a production license is a "door-to-door" to the market November 16, 2016, TianzhiHang Corporation has obtained the National Food Drug Supervision and Administration (CFDA) issued a surgical robot medical device registration license, becoming the only international orthopaedic robot system capable of performing trauma orthopaedic, spinal surgery On June 26, 2018, Daai's exoskeleton robot obtained the CFDA registration certificate, becoming the first lower limb exoskeleton robot certified by the CFDA, and the first type ii innovative medical device in China after the implementation of the second type of innovative medical device "green channel" review and approval policy with the improvement and improvement of the system of transformation of scientific and technological achievements, research institutes have issued the transformation rules, so that the basic research results can be converted into products, there are channels to embrace the market With research institutes "blood" innovation leaders gradually to the market, to promote the original results of product transformation "Our vascular intervention robot is developed independently on the basis of more than ten years of accumulation of the Chinese Academy of Sciences Automation, after the transformation of laboratory principle prototype to product prototype, through technological innovation to solve some of the shortcomings that still exist in foreign products Feng Zhenball said There is still a long way to go for China's medical robot products to enter the clinic from the laboratory, including verifying its safety and efficacy in clinical trials and then registering for approval The Priority Approval Procedure for Medical Devices came into effect on January 1, 2017 For some of the domestic three and import edgy medical device registration applications with obvious clinical advantages to implement priority approval, which for all kinds of high-quality medical devices to bring great impetus to the rapid popularization data show that Hagong University in laparoscopic, orthopaedic, interventional surgery and other fields to carry out research, the Chinese Academy of Sciences Automation Institute, Shenyang Institute, Shenzhen Hospital and other fields of vascular intervention, orthopaedics and other fields to carry out research, Tianjin University in laparoscopic, microsurgery and other fields, Beijing Polytechnic University in soft tissue puncture, craniofacial surgery and other fields to carry out research, Fudan, Zhejiang University, etc Many of them have been financed, opening the way for robots to enter the market
