Current Status of Patent Research on Medical Micro-nano Robot

Micro-nano robots have broad applications in sewage purification and DNA testing. Micro- nano robots have significant potential in the medical field， as they have higher therapeutic efficiency and safety than conventional treatment methods. Meanwhile, micro-nano robots provide a new method for treating many diseases. Therefore, as an emerging medical method, the development trend of micro-nano robots is receiving increasing attention. This study aims to provide a new approach to treating diseases that reduces the costs and risks of traditional medical treatments. This paper introduces the operation mechanism of micro-nano robots, summarizes representative patents of micronano robots in medicine, summarizes the classification according to the different driving modes, and analyzes their advantages, disadvantages, and uses. Through the investigation of many micro-nano robots, the current medical micro-nano robots are summarized and analyzed as generally challenging to prepare, difficult to control accurately, with a low degree of intelligence, and poor accuracy. Finally, the future development trend of medical micro-nano robots is overlooked. Optimizing the preparation method can significantly reduce the production cost of micro-nano robots. Mixing and driving modes can drive the micro-nano robots more efficiently. Improving the intelligence of micro-nano robots can allow them to perform more complex tasks. Improved imaging techniques allow for more precise control of the micro-nano robots. Finally, the article forecasts that micro-nano robots will develop towards the trends of non-toxic, intelligent, and controllable directions.
