Outline of Final Research Achievements |
This study proposed novel magnetic micro-actuators capable of two kinds of functions required for a next-generation capsule endoscope. One is a brush cytology function, in which the magnetic actuator can perform four different motions including projection/pullback/scrape modes for the brush and a rotation mode for the capsule body. Each mode is selected by the direction of external magnetic fields. The other is a drug delivery function, in which a screw type actuator can press a drug tank and extend anchors for stay. This operation is performed by a rotating magnetic field. As a result of the examination in a simulated small intestine and small intestines of cow and pig, both functions exhibited the desired performance.
