Testing and Evaluation of Foldable Biopsy Tools for Active Capsule Endoscope

摘要

This paper describes the development of passive foldable biopsy tools and the improvements of active capsule endoscope as future medical devices for intestinal inspection. The present's active locomotive capsule endoscope is a micro-robot that can travel along the way of the digestion system with wireless control and position abilities. The capsule endoscope has been integrated with novel micro-biopsy tools armed to extract tissue samples from the small and larger intestine. The entire capsule system has abilities of target random biopsies at any position of the intestinal system by magnetic control and shortly 3D sensor localization and position methods. The Active capsule endoscope system could reach the target place, be controlled at real-time by the doctor, and be able to cut-off and keep on-board of its body's as much as possible of intestinal tissue for further analysis. The biopsy mechanism is a novel passive triggered mechanism with a highly accurate magnetic actuator for positional control and localization.
