Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is that the axial length of the capsule shell is large while the existing capsule endoscope increases the shooting angle range, which leads to a decrease in the accuracy of the images captured by the endoscope, and the impact of the endoscope on the intestinal The detection error of the road is large

Embodiment 1

[0054] This embodiment provides a capsule endoscope, such as Figure 1 to Figure 6 As shown, it includes a capsule shell 1 and two sets of image acquisition mechanisms.

[0055] Such as figure 1 and figure 2 As shown, the capsule shell 1 has an installation cavity. Optionally, the capsule shell 1 includes a middle shell 11 and a transparent shell 12 detachably arranged on openings at both ends of the middle shell 11 . For example, the transparent shell 12 is sleeved outside the opening of the middle shell 11, and is connected by a buckle, or threaded, or directly socketed, or other existing detachable connection methods. The transparent shell 12 forms an observation window, which is also convenient for the lens to pass through the transparent shell 12 to collect images of the intestinal tract; of course, the middle shell 11 can also be made of a transparent material. Optionally, as in figure 1 As shown, the capsule shell 1 is in the shape of a rugby ball, or a capsule of ...

Embodiment 2

[0079] This embodiment provides a capsule endoscope, such as Figure 7 and Figure 8 As shown, it is compared with the capsule endoscope provided in embodiment 1, the difference is:

[0080] The structures of the power supply components are different. The first power supply component 22 and the second power supply component 32 are not provided with the above-mentioned relief holes and installation holes, and the first power supply component 22 and the second power supply component 32 are still arranged in the first space. At this time, the first power supply component 22 is clamped between the first circuit board 21 and the second circuit board 31, the second power supply component 32 is clamped between the first circuit board 21 and the second circuit board 31, and the second power supply component 32 is clamped between the first circuit board 21 and the second circuit board 31. A power supply part 22 and a second power supply part 32 are arranged away from the first body 23...

Embodiment 3

[0084] This embodiment provides a capsule endoscope. Compared with the capsule endoscopes provided in Embodiment 1 and Embodiment 2, the difference lies in:

[0085] The first lens 232 is located outside the first circuit board 21, the second lens 332 is located outside the second circuit board 31, and the projections of the first body 231 and the second body 331 on the above-mentioned cross section in the first space are along the capsule shell. There is an overlapping portion in the radial direction, the first body 231 no longer passes through the second circuit board 31, the second body 331 no longer passes through the first circuit board 21, the first power supply part 22 and the second power supply part 32 are set In the first space, the projections of the two power supply components on the above-mentioned cross-section may have no or overlapping parts along the radial direction of the capsule shell, and the axial length of the two sets of image acquisition mechanisms can ...

Abstract

The invention provides a capsule endoscope which comprises a capsule shell and at least two sets of image acquisition mechanisms, two circuit boards of the two sets of image acquisition mechanisms are oppositely arranged in the axial direction of the capsule shell, and a first space is formed between the two circuit boards; the image collectors of the two sets of image acquisition mechanisms are staggered in the radial direction of the capsule shell, and the lenses of the image collectors are arranged in a back-to-back manner. The projection of at least part of the power supply component and / or the image collector of one set of image collection mechanism and part of the power supply component and / or the image collector of the other set of image collection mechanism located in the first space on the cross section where the axis of the capsule shell is located have an overlapped part in the radial direction of the capsule shell, so that the length L of the capsule shell is smaller than the length L' of an existing capsule shell, the size of the capsule endoscope is small while the shooting angle range is enlarged, the containing area needing to be emptied in the intestinal tract is small, and the detection accuracy of the endoscope on the intestinal tract is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a capsule endoscope. Background technique [0002] Capsule endoscopes in the prior art mainly include a capsule casing, a battery disposed in the capsule casing, a circuit board of a main control module, a camera, and a plurality of lighting lamps. Among them, the battery is electrically connected to the circuit board to supply power to the circuit board, the camera is fixed on the circuit board, and the camera and the battery are distributed on both sides of the circuit board, and multiple lighting devices are fixed on the circuit board and distributed around the camera. the periphery of the lens. When the capsule endoscope with this structure collects images in the human intestinal tract, the lens of a camera can only capture images of a local angle range in the intestinal tract, resulting in a limited shooting area, and the collected images cannot update the situa...
