Conceptual design of micro-hydraulics system for active and biopsy capsule endoscope robot

Abstract

Capsule endoscope is commercial design product used as a medical device for endoscopy test in the small intestine preferably. This paper presented a novel conceptual design and power mechanism in order to perform a capsule endoscope robot with micro-hydraulic biopsy tools system. The capsule endoscope presented can moves as active device, powered externally by an electro-magnetic actuation system (EMA). The EMA system can be frequency adjust to activate the micro-hydraulic pump as the main power generator to perform the micro-actuator and/or micro-biopsy tool. The conceptual design is focused in two capsule containers; these are proposed to be able to obtain additional space for the biopsy tools. Preliminary test of the micro-pump power by EMA system are presented for future application of capsule endoscope with active motion maneuvers and micro-biopsy tools operation in real-time.
