MAGNETIC CONTROL DEVICE OF CAPSULE ENDOSCOPE AND METHOD FOR CONTROLLING MOVEMENT OF CAPSULE ENDOSCOPE IN TISSUE CAVITY

WIPO Patent Application WO/2020/252940

A1

A magnetic control device (30) of a capsule endoscope (10), the capsule endoscope (10) comprising at least a first magnet (11) and an imaging device (12), wherein the capsule endoscope (10) is located in a tissue cavity (3); the magnetic control device (30) comprises a second magnet (31) and a first induction coil (32) distributed around the second magnet (31); the magnetic control device (30) is configured to produce a drive force to the capsule endoscope (10) so that the capsule endoscope (10) moves from a first position (P1) in the tissue cavity (3) to a second position (P2) toward the opposite side in the tissue cavity (3). When the capsule endoscope (10) is close to the second position (P2), a variable magnetic field is controlled to decelerate the capsule endoscope (10) to a predetermined speed, and the magnetic control device (30) is configured to generate the variable magnetic field for the capsule endoscope (10). In said case, the movement path of the capsule endoscope (10) in the tissue cavity (3) may be reasonably optimized, which may comprehensively inspect the tissue cavity (3) while protecting the inner wall of the tissue cavity (3).
