カプセル型内視鏡の誘導装置
Document Type and Number:
Japanese Patent JP6667176
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a guiding device of a capsule endoscope in which the capsule endoscope being taken is guided by using magnetic force and a simple constitution is provided.SOLUTION: A guiding device of a capsule endoscope includes a capsule endoscope, and magnetic field action means for guiding and operating the capsule endoscope from outside the body by applying magnetic force in the capsule endoscope. The magnetic field action means includes: a first permanent magnet 21a and a second permanent magnet where the same poles are arranged to face each other; and a magnetic spacer material mounted by abutting an end face between the opposed magnetic poles of the first permanent magnet and the second permanent magnet, and having a cross section becoming a gear-wheel shape.SELECTED DRAWING: Figure 2
