Problems solved by technology

[0006] However, the prior art described above has a structure in which image data is stored by an image processing device outside the body in a form associated with information on a rotating magnetic field at the time of image data acquisition, leaving room for high-precision rotation correction. next question
[0007] That is, although an arrangement in which a state of rotation is detected when an image is acquired would provide high-precision rotation correction, such an arrangement has not been disclosed in the conventional art

Embodiment 1

[0086] Embodiment 1 will be described with reference to FIGS. 1 to 9 .

[0087] As shown in FIGS. 1 and 2, a capsule medical system 1 according to Embodiment 1 of the present invention includes: a capsule medical device (capsule endoscope) 3 (hereinafter referred to simply as "capsule endoscope") 3 used as a capsule endoscope. ”), which is inserted from the mouth or anus into the body cavity of a subject not shown, and enables image acquisition, diagnosis and treatment, etc. to be performed in the body cavity; and a magnetic field generating device 9, which is positioned to surround The object, ie, is positioned outside the object. The magnetic field generating device 9 includes: a rotating magnetic field generating device 4 for applying a magnetic field to the capsule 3; and a magnetic field generating control device (or power control device) 5 for controlling the supply of a driving current for A rotating magnetic field is generated at the rotating magnetic field generating...

Embodiment 2

[0171] Next, Embodiment 2 according to the present invention will be described with reference to FIGS. 10 and 11 . FIG. 10 shows the structure of a bladder medical system 1B according to Embodiment 2 of the present invention.

[0172] This capsule medical system 1B includes: a capsule 3B; a magnetic field generating device 9 ; a processing device 6B; a display device 7 ;

[0173] The capsule 3B generally has the same structure as the capsule 3 shown in FIG. 2 except for a structure in which the captured image signal captured by the image capture device 14 is transmitted in the form of an analog signal modulated by the wireless communication circuit 22 . That is to say, the capsule 3B generally has the same structure as that shown in FIG. 2 except that the signal processing circuit 20 and the memory 21 for A / D conversion, image data compression, etc. are not included.

[0174] Furthermore, the capsule control circuit 23 includes a timer 23a for controlling the illumination dev...

Embodiment 3

[0187] Next, Embodiment 3 according to the present invention will be described with reference to FIGS. 12 and 13 . FIG. 12 shows the structure of a capsule medical system 1C according to Embodiment 3 of the present invention.

[0188] Although the capsule 3C according to this embodiment has only the function of transmitting captured images in the same manner as the capsule 3B shown in FIG. Send compressed image data.

[0189] Furthermore, according to the present embodiment, the next image acquisition is started after a predetermined period of time after the compressed image data is transmitted. That is to say, the capsule 3C performs the next image acquisition operation in parallel with the processing device 6C's operation of decompressing the compressed image data, etc.

[0190] Furthermore, the capsule control circuit 23 includes a timer 23a therein in the same manner as shown in FIG. 10 . After the steps from the start of image capture performed by the image capture dev...

Abstract

A medical system includes: a medical device to be inserted into the body cavity; a rotating device for the medical device for rotating the medical device around the insertion axis; an image pickup device provided to the medical device; and an image capturing timing detection device for detecting a signal regarding image capturing timing performed by the image pickup device. Furthermore, the medical system includes: a rotating angle acquisition device for acquiring the rotating angle of the rotating device for the medical device regarding the image capturing timing in response to the output of the image capturing timing detection device; and an image acquisition device for performing rotation processing for the image captured by the image pickup device based upon the information regarding the rotating angle acquired by the rotating angle acquisition device, thereby acquiring the image subjected to a rotation processing.

Description

technical field [0001] The present invention relates to a medical system comprising a medical device having a function of generating propulsion in a body cavity by its rotation. Background technique [0002] The following various types of medical devices have been proposed, each of which is inserted into a body cavity and has a function of generating propulsion force etc. by its rotation, thereby allowing inspection of the body cavity . [0003] For example, Japanese Unexamined Patent Application Publication No. 2003-299612 discloses a capsule endoscope system having a capsule endoscope guided in a lumen by applying a rotating magnetic field to rotate the capsule endoscope. Capsule endoscope function. [0004] In the prior art disclosed in the above-mentioned patent documents, image data collected by a capsule endoscope is sent to an image processing device outside the body. The image processing device stores the received image data and the data of the rotating magnetic f...
