The Chinese University of Hong Kong (CUHK) Engineering College has collaborated with overseas researchers to develop a micro- medical robot that can accurately deliver drugs to specific parts of the body. It can be used in cancer, cerebral infarction, retinal degeneration and other diseases in the future. Targeted therapy.
The new robot is porous and has a length that is close to the diameter of the hair. In a tiny space, how to power a robot and how to operate it becomes two major problems.
Professor Zhang Li of the Department of Mechanical and Automation Engineering of Zhongda University said at a press conference on the 12th that micro-manipulators can accurately transfer drugs to tiny parts of the human body through the external magnetic field control, and shuttle through blood vessels, eyes and brain. "Traditional treatment can only be passively administered through blood vessels, and micro-robots can achieve active targeted drug delivery, sending drugs to places that are difficult to reach with traditional medical methods." Zhang Lizhi, the result of this research on wirelessly controlled micro-medical machinery Human development has taken an important step.
He continued to point out that the use of micro-mechanical treatment has the advantages of small wounds and high precision, and can reduce the side effects caused by invasive medical methods. However, it still takes time to transform from scientific research to application: "The future application is actually expected to be practical for nearly ten years. Great possibility."
The above research results will be published on the cover of the new internationally renowned academic journal AdvancedMaterials. Since the concept of micro-robots has been proposed since the 1950s, it has been successfully practiced in the medical field, such as the use of capsule endoscopes to detect the human intestines, and micro-mechanics to complete retinal surgery.
