Through the swallowing, breakthrough research has been made on the research of capsule medical micro-robots that can be spirally moved in the human intestine. Chinese scientists have now developed prototypes and achieved good experimental results in isolated pig intestines. In vivo interventional examination and treatment have the advantages of safety and minimally invasive, and quickly become the mainstream in the field of medical engineering. The micro-digestive capsule endoscope developed by the people uses the gastrointestinal tract peristalsis to perform an entire area inspection, and the inspection image is transmitted wirelessly by an embedded CMOS micro camera. However, it is slow to walk and there is a visual blind zone; when the diseased tissue is missed, it is impossible to return actively, so that some medical operations cannot be completed. Therefore, it is necessary to develop a capsule robot that can be swallowed and can be controlled by an external cableless drive. Through continuous technical research, Zhang Yongshun, an associate professor of the Institute of Modern Manufacturing Technology of the School of Mechanical Engineering of Dalian University of Technology, proposed a prototype of a variable diameter spiral structure capsule robot based on a new driving principle driven by an external rotating magnetic field. Under the action of the wedge effect principle, the pressure of the hydrodynamic membrane and the driving ability in the intestinal tract are significantly improved. Experiments show that the robot can realize vertical swimming in the intestine of pigs, improve the adaptability in the intestine, and lay a foundation for practical use. At present, the research has made breakthrough progress and completed the research on miniaturization. The robot has reached the shape of swallowable and the experimental effect is good. At the same time, in order to be practical, the research team is working on the key technology of the capsule robot in the bending environment. the study. The ultimate goal of the project is to realize the puncture, diagnosis, application, sampling and other interventional treatments by robots without cable control in vitro. It has broad application prospects and is of great significance for the development of medical engineering.
