no. 1 Embodiment approach ＞
[0023] Such as figure 1 and figure 2 As shown, a capsule endoscope (hereinafter referred to as "endoscope") 10 as a capsule medical device according to this embodiment accommodates a circuit board 20 having a plurality of substantially circular substrate portions in a bent state. It is sealed inside the capsule-shaped housing 11 .
[0024] The endoscope 10 is a device introduced into the subject's body that captures images inside the subject at predetermined time intervals after being swallowed by the subject. In addition, it is possible not only to wirelessly transmit image data obtained inside the body to the outside, but also to receive a signal from the outside and perform control based on the signal.
[0025] The housing 11 is composed of a cylindrical main body 12 and substantially hemispherical end cover parts 13A, 13B at both ends of the main body 12 . The end cover portion 13A is made of a transparent material. The main body portion 12 and the end cover portion 1...
no. 2 Embodiment approach ＞
[0054] Hereinafter, an endoscope 10A according to the second embodiment will be described. Since the endoscope 10A is similar to the endoscope 10 of the first embodiment, the same components are given the same reference numerals and their descriptions are omitted.
[0055] Such as Figure 8 As shown, the endoscope 10A is of a so-called dual-lens type having two imaging chips that capture images of fields of view in opposite directions, that is, an imaging chip 22A and an imaging chip 25A.
[0056] Such as Figure 8 As shown, there are a first lighting board part 21, a first imaging board part 22, a transmitting board part 23, a receiving board part 24, a second imaging board part 25, and a second lighting board part 26 arranged in a row through each connection part in sequence. The circuit board 20A constituting the endoscope 10A.
[0057] The first illumination board unit 21 and the second illumination board unit 26 have substantially the same configuration, and the first ...

Abstract
In a capsuleendoscope 10, on an inside of a capsule type housing 11 including a cylindrical main body section 12 and two semispherical end cover sections 13A and 13B and having a rotationally symmetrical shape with respect to a center axis O of the housing 11, an image pickup board section, a transmission board section, and a reception board section are housed such that principal planes of the image pickup board section, the transmission board section, and the reception board section are orthogonal to the center axis. A coil wire of at least one of a transmission coil 40 formed by a transmission coil wire and a reception coil 50 formed by a reception coil wire, respective principal planes of which are orthogonal to the center axis O, is disposed on the end cover section 13A or 13B side of the housing 11.
Description
technical field [0001] Embodiments of the present invention relate to a capsule-type medical device introduced into the body, and more particularly, to a capsule-type medical device including a receiving coil for receiving external signals and a transmitting coil for transmitting information acquired in the body as an information signal to the outside. medical device. Background technique [0002] In recent years, capsule-type endoscopes having an imaging function and a wirelesstransmission function have appeared. The capsule endoscope moves with peristaltic motion inside the digestive canal such as the stomach and small intestine after being swallowed by the subject until it is naturally excreted, and uses the imaging function to image the inside of the organ. [0003] Images captured by the capsule endoscope while moving in the digestive canal are transmitted as image signals to an external device installed outside the subject through a wirelesstransmission function, an...
