摘要

It is possible to actively control at least position or direction of imaging field-of-view in an examinee and shortly and surely observe a desired portion in the examinee. An into-examinee introduction system includes an encapsulated endoscope (1) introduced into an examinee (100) and a permanent magnet (3). The encapsulated endoscope (1) for capturing an image in the examinee (100) has an imaging unit fixedly arranged in a case. Moreover, the encapsulated endoscope (1) includes a drive unit for changing at least a position or a posture of the case in a liquid (2a) introduced into the examinee (100). The permanent magnet (3) controls operation of the drive unit changing at least the position or the posture of the case in the liquid (2a).
