Abstract

The importance of colonoscopies on the one hand and the drawbacks of the conventional instrumentation on the other have led to research into alternative colonoscopic devices. The main question for the development of such devices is the method of locomotion along the slippery and flaccid intestinal tube. This paper suggests a new intestinal locomotion method based on friction manipulation between the device and the intestinal wall. A new concept to manipulate friction is described. The concept is based on the active alterations of the friction between the device and the intestinal wall and it is inspired by the locomotion of biological species such as snails and starfish.

摘要

一方面，结肠镜检查的重要性，另一方面，传统器械的缺点，促使人们对替代结肠镜设备进行研究。开发此类设备的主要问题是如何在光滑且松弛的肠管中移动。本文提出了一种基于设备与肠壁之间摩擦操纵的新型肠道移动方法。描述了一种操纵摩擦的新概念。该概念基于设备与肠壁之间摩擦的主动改变，其灵感来源于蜗牛和海星等生物的移动方式。
