The Intelligent Hydraulic prosthetic knee joint achievement of the Rehabilitation Engineering and Technology Research Institute of Shanghai University of Technology
The Rehabilitation Engineering and Technology Research Institute of Shanghai University of Technology has successfully developed the first intelligent hydraulic prosthetic knee joint in China - i-KNEE.. The knee joint can automatically adapt to the wearer's walking speed, assisting them in walking naturally in diverse road conditions. Traditional hydraulic knee joints require technicians to adjust a large number of parameters according to the walking speed habits of different individuals, and usually only have one mode, which cannot be automatically adjusted according to road conditions, resulting in poor comfort during use. The i-KNEE has an autonomously adjustable robot joint system, consisting of electromechanical devices and electronic control systems. The entire structure is equipped with multiple sensors, which can monitor the wearer's motion information in real time. Through computer chip analysis and processing, it can achieve automatic recognition of the patient's gait phase, pace, and road conditions and terrain. During the walking process, it uses intelligent algorithms to automatically adjust walking damping, adapt to the wearer's walking speed to achieve excellent walking gait, and can analyze sensor data to predict the wearer's action intention, helping patients walk in various road conditions such as flat ground, stairs, and slopes. When the wearer trips, it can also automatically lock the knee joint to prevent falling. At present, i-KNEE has conducted clinical wearing tests on patients in prosthetic assembly institutions, and is further improving its technology and promoting industrialization. This research and development achievement represents a major breakthrough in the field of prosthetics in China, reaching the advanced level of international intelligent prosthetic knee joint technology, and is expected to fill the product gap of intelligent hydraulic prostheses on the knee in China.
Research progress and patents of the Institute of Artificial Limbs Science of the Ministry of Civil Affairs
The Institute of Artificial Limbs Science of the Ministry of Civil Affairs was originally a research institution directly under the Ministry of Civil Affairs and the only one in the country specializing in the research, development, and application of prostheses, orthotics, and rehabilitation devices. It was established in 1979 with the approval of the National Science and Technology Commission.. In 2006, it was renamed as the National Rehabilitation Assistive Equipment Research Center. The research institute has achieved a series of important scientific research results, always tracking the forefront of the world, and has won dozens of awards at various levels and more than ten national invention patents. Its patents include "adjustable resistance and locking dual-purpose prosthetic single axis knee joint" and "manufacturing technology for skeletal lower limb prostheses with simulated cortex". These achievements are of great significance in the field of rehabilitation aids and have effectively promoted technological progress in the industry.
The core technology of the neural prosthetic team in the Rehabilitation Engineering Technology Research Laboratory of Suzhou Medical Institute
The core key technology of the neural prosthetic team in the Rehabilitation Engineering Technology Research Laboratory of Suzhou Medical Institute is to develop an intelligent neural prosthetic hand based on force tactile perception and feedback, focusing on the motor function reconstruction technology and perception compensation feedback technology of neural prostheses, and solving the current technical bottleneck of low control robustness and weak multimodal information perception ability of prosthetic hands.. In related competitions, the technical team developed a prosthetic hand with dual degrees of freedom for both the hand and wrist. By relying on a precise body drive control system, they achieved synchronous and rapid control of the prosthetic hand's multiple degrees of freedom. When completing tasks such as grasping heavy objects and agile operations specified in the competition, they improved task completion speed and success rate, and achieved excellent results in events such as the Global Semi Robot Olympic Challenge. In the future, the team will continue to conduct in-depth research on the reconstruction of motion perception function of neural prosthetic hands, and quickly translate the technological achievements into the practical needs of amputees with disabilities.
Peking University's patent for intelligent prosthetic system and control method
Peking University has obtained the patent for intelligent prosthetic system and control method.. This patent relates to an intelligent prosthetic system and its control method, including prosthetic hands, RGB and Depth data acquisition devices, object and prosthetic hand perception modules, prosthetic hand action prediction modules, and controllers. The object and prosthetic hand perception module can obtain point cloud information of the object and 6D posture of the prosthetic wrist, and the prosthetic hand action prediction module predicts the prosthetic hand action gradient based on this information. This patent achievement provides new technological support and innovative ideas for the development of intelligent prosthetics.
Xiangyu Medical's multi degree of freedom upper limb prosthesis invention patent
Xiangyu Medical has obtained important invention patents in the field of prosthetics, such as "a multi degree of freedom upper limb prosthesis".. The upper limb prosthesis adopts synchronous control of four fingers and thumb, and its structural setting can meet the multi degree of freedom wrist swing. The implementation of these degrees of freedom enables people with disabilities to better operate various daily necessities, tools, and equipment, improve their self-care and work abilities, and enhance their quality of life. At the same time, the setting of finger elastic pads and palm pads can provide some protection while grasping objects. This device also improves the stability of the prosthetic device, allowing amputees to use the prosthetic more stably. In the field of prosthetic technology research in China, enterprises or research institutions such as Shanghai University of Technology, the Institute of prosthetic science of the Ministry of Civil Affairs, Suzhou Medical Institute, Peking University, and Xiangyu Medical have achieved significant results.. These achievements cover multiple fields such as upper limb prosthetics, lower limb prosthetics, intelligent prosthetic systems, and control methods, continuously promoting the development of prosthetic technology in China and making important contributions to improving the quality of life and rehabilitation level of people with disabilities. In the future, we believe that with the continuous progress and innovation of technology, China's research on prosthetic technology will achieve more breakthrough results, benefiting more disabled people.
