Report from this newspaper (Reporter Sun Qiru) The world’s first multi-channel pan-vascular interventional surgical robot, a new generation of implantable left ventricular assist device, micro-nano photoelectric control technology and micro-nano robots... The Zhongguancun International Frontier Science and Technology Innovation Competition in the field of medical devices recently Held in Zhongguancun Medical Device Park, a number of cutting-edge life and health technologies that are internationally leading and fill domestic gaps were unveiled in Beijing.
Heart failure, known as the "stumbling block of life", is a serious manifestation or late stage of various heart diseases and has become one of the major diseases that affects the quality of life. Once heart failure reaches an advanced stage, patients can only rely on heart transplantation or left ventricular assist device implantation for treatment. According to incomplete statistics, nearly one million patients with end-stage heart failure need treatment in my country every year. There are only 600 heart transplants performed in China every year, and a large number of patients die while waiting for heart transplants.
In China, the core technology of artificial heart has been blank for a long time. In order to break the monopoly of foreign technology, the aerospace Taixin team presented in this competition is based on more than 50 years of aerospace servo technology experience and more than ten years of "medical engineering", and has overcome pump-machine integration, magnetic fluid dual suspension, and internal flow. Using core technologies such as channel optimization and driver dual redundancy, the HeartCon implantable left ventricular assist device independently developed by the team achieves the characteristics of small size, light weight, low temperature rise, etc., greatly reducing the burden on patients, and is superior to international hemolysis indicators in terms of hemolysis indicators. Similar products.
In recent decades, the annual implantation volume of pacemakers has increased year by year, with the growth rate maintaining at around 10%. However, the domestic pacemaker market is still dominated by foreign companies. The "Self-Powered Leadless Cardiac Pacemaker" project demonstrated at the competition site roadshow uses self-developed biological self-powered technology to break through the existing pacemaker's short service life and large trauma pain points, and is expected to enable minimally invasive implants The service life of the pacemaker has been increased from 10 years to 20 years, and even "once implanted, used for life".
After a brain-computer interface processor the size of two coins was implanted into the skull of a high paraplegic patient, after three months of home rehabilitation training, the patient could drive pneumatic gloves through brain electrical activity to achieve brain-controlled functions such as drinking water autonomously. The "Commercial Application of Brain-Computer Interface Technology" project unveiled at the competition also made the audience marvel at the disruptive changes brought about by cutting-edge technology.
Ten projects, including the commercial application of brain-computer interface technology, vascular interventional surgery robots, and a new generation of implantable left ventricular assist devices, finally stood out from many projects and won the top ten in the medical device field of the 7th Zhongguancun International Frontier Technology Competition.
Zhang Yulei, member and deputy director of the Beijing Municipal Science and Technology Commission and Zhongguancun Management Committee, said that the medical and health industry is one of the "dual engines" that promotes Beijing's innovative development. In recent years, Beijing has successively launched the "Action Plan to Accelerate Collaborative Innovation in Medicine and Health" to promote the rapid growth of the medicine and health industry and lay a solid foundation for the city's medicine and health industry to grow into a trillion-level industry. As an event section of the Zhongguancun Forum, the Frontier Competition is not only a high-level international cutting-edge science and technology competition platform for external exchanges, but also an important means of selecting and incubating cutting-edge technology enterprises and teams.
