Background Previous reports have described several candidates, which have the potential to replace colonoscopy, but to date, there is still no device capable of fully replacing flexible colonoscopy in the management of colonic disorders and for mass adult population screening for asymptomatic colorectal cancer. Materials and methods NASA developed the TRL methodology to describe and define the...
Background Conventional colonoscopy requires a high degree of operator skill and is often painful for the patient. We present a preliminary feasibility study of an alternative approach where a self-propelled colonoscope is hydraulically driven through the colon. Methods A hydraulic colonoscope which could be controlled manually or automatically was developed and assessed in a test bed modelled on...
Exploration of the colon with semi-autonomous devices represents a challenge for present researchers in this field. Characteristics, conditions and topography of the colon are unpredictable and sensory feedback from a device within the colon is limited, therefore one key challenge is to provide reliable data on which to base decision-making.
