ACTIVE ROBOTIC ENDOSCOPE FOR MINIMALLY INVASIVE SURGERY

摘要： <正>A robotic endoscope is mainly composed of a tactile array sensor, soft mobile mechanism for earthworm locomotion and turning mechanism based on shape memory effect. The tactile array sensor can provide the information about magnitude and orientation of interacting forces between the robotic endoscope and the wall of gastrointestinal tracts. The soft mobile mechanism contacts gastrointestinal tracts with air-in inflatable balloons, so it has better soft and non-invasive properties. The turning mechanism can be actively bent by shape memory alloy components and conform to the complex shape of gastrointestinal tracts. The working principle of robotic endoscope is dealt with. ... （共5页）
