Capsule micro-robot in the human stomach and intestines for non-invasive examination and small injury surgery, to reduce the patient's pain, improve the safety of the examination and surgery and reduce the cost of medical care are of great significance. Now the general method of treating gastrointestinal diseases in China is to use endoscopic fluoroscopy, radiography or surgical examination, which is not only costly but also painful for patients. The micro-robot is not only low-cost and time-saving, but also does not cause pain to the patient.
The ultimate goal of the capsule micro-robot is to form a medical micro-robot system that integrates in vivo peeping and diagnostic treatment, and safely performs peeping, diagnostic, medication application, sampling and other interventional medical operations through in vitro cable-free drive control and attitude adjustment. This research has important scientific significance for improving human life and quality of life, avoiding external surgery on the human body caused by trauma and disability, once successfully developed and applied in the clinic, can reduce the patient's pain, shorten the recovery time, reduce medical costs, will have a great impact on the development of medical engineering.
