Abstract

This paper presents a novel mechanism and design of capsule endoscope in order to perform an active locomotive capsule endoscope (ALICE) robot integrated with micro-hydraulic pump for drug delivery function. The proposed locomotive capsule endoscope can actively move and investigate in gastrointestinal tract, powered externally by an electro-magnetic actuation (EMA) system. To perform a drug pumping function, the rotating frequency of the active hydraulic pump can be adjusted by the EMA system. The novel capsule endoscope with the micro-hydraulic pump is focused on target drug delivery function. The capsule endoscope is able to target suspicious region and release controllable amount of drug. Through preliminary tests of the locomotive capsule endoscope with the micro-pump, the feasibility of the locomotion and the drug releasing of the novel capsule endoscope will be presented. The micro-hydraulic pump for a drug delivery function will be a potential component for a future capsule endoscope with active maneuverability, diagnostic and therapeutic functions.
