Study on a New Type of Rotated Insertion Colonovideoscope Robot

Conventional colonoscopy frequently causes pains to patients and sometimes even leads to enterobrosis and other medical accidents. This occurs mainly because the operation technique of colonoscopy is so complicated that there are only a small amount of professional doctors can complete the insertion procedure in a short time. Therefore, a new type of rotated insertion Colonovideoscope robot is developed. The robot with an adopting self-propelled motivating device and direction control system can creep into large intestine just like a snake. Having designed the insertion tube and spiral structure, we chose multiple sorts of materials to manufacture them. Moreover, insertion test using human large intestine model was finished and the questions in test were analyzed to improve the original structure. The test result shows that some certain propulsion in large intestine model can be realized. This study founds the basis to develop this new robot for colonoscopy in the future.Engineering, BiomedicalEngineering, Electrical & ElectronicCPCI-S(ISTP)
