Embodiment approach 1

[0044] figure 1 It is a schematic diagram showing a configuration example of an in-vivo information acquisition system including the capsule endoscope according to Embodiment 1 of the present invention. Such as figure 1 As shown, the in-subject information acquisition system includes: a capsule endoscope 2 that captures images inside the subject 1 ; receiving device 3 ; image display device 4 for displaying images of the subject 1 received by receiving device 3 ; and portable recording medium 5 for exchanging data between receiving device 3 and image display device 4 .

[0045] The capsule endoscope 2 has an imaging function of sequentially capturing images of the inside of the subject 1 in time series and a wireless communication function of sequentially wirelessly transmitting the captured images of the inside of the subject 1 to the outside. Furthermore, the specific gravity of the capsule endoscope 2 is set so that it can float on the surface of a desired liquid such a...

Embodiment approach 2

[0088] Next, Embodiment 2 of the present invention will be described. In the first embodiment described above, one imaging unit 13 is fixedly arranged inside the casing 11 and fixedly arranged on the opposite side of the center of gravity G of the capsule endoscope 2 with the center C of the casing 11 as a boundary. Mode 2 is a multi-eye capsule endoscope in which the imaging unit is fixedly arranged on the opposite side and the same side (centroid side) of the capsule endoscope's center of gravity with the center of the housing as a boundary.

[0089] Figure 4 It is a schematic side sectional view schematically showing a configuration example of the capsule endoscope according to Embodiment 2 of the present invention. Such as Figure 4 As shown, the capsule endoscope 20 of the second embodiment includes a housing 21 instead of the housing 11 of the capsule endoscope 2 of the first embodiment, a control unit 26 instead of the control unit 16, and an illumination unit 22 and...

Embodiment approach 3

[0128] Next, Embodiment 3 of the present invention will be described. In Embodiment 2 above, the center of gravity G of the capsule endoscope 20 is set on the central axis CL of the casing 21, and the imaging direction A1 of the imaging unit 13 is made parallel to the central axis CL of the casing 21. However, in this In Embodiment 3, the center of gravity G of the capsule endoscope is also set at a position separated from the central axis CL, and the direction inclined to the opposite side of the center of gravity G with respect to the central axis CL in the longitudinal direction of the housing is the direction of the imaging unit 13. shooting direction.

[0129] Figure 6 It is a schematic side cross-sectional view schematically showing a configuration example of the capsule endoscope according to Embodiment 3 of the present invention. Such as Figure 6 As shown, the capsule endoscope 30 of the third embodiment has a housing 31 instead of the housing 21 of the capsule en...

Abstract

It is possible to provide an encapsulated endoscope which can float on a liquid introduced into a large organ and can surely capture a wide-range and clear image of the interior of the organ. The encapsulated endoscope (2) includes a case (11) of a capsule shape and an imaging unit (13) fixed and arranged in the case (11). While the encapsulated endoscope (2) is floating on the surface of the liquid introduced into the organ of an examinee, the imaging unit (13) captures an image of the interior of the organ. In such an encapsulated endoscope (2), the center of gravity G of the encapsulated endoscope (2) is set at the position apart from the center C of the case (11). The case (11) is maintained in a particular floating posture. The optical characteristic of the imaging unit (13) is set in accordance of the object in the imaging direction (A1) of the imaging unit (13) which is decided by the floating posture of the case (11).

Description

Technical field [0001] The present invention involves the internal organs that the patients such as the patient, which are taken inside the patients such as the internal organs to perform the capsule endoscope of the image inside the internal organs. Background technique [0002] In the past, a capsule -type endoscope with swallow -type endoscope with shooting and wireless communication functions was developed in the field of endoscope.The body information obtains the system.In order to observe (inspection), the capsule -type endoscope moves from the mouth of the detected body until it is naturally excreted, and moves the internal movement of internal organs such as gastric and small intestine through peristalsis.Take the image inside the internal organs (below, sometimes called the image in the body) inside the internal organs of the detected body. [0003] During the movement of the capsule in the inspection, the image in the inspection body by the capsule -type endoscope was s...
