[0032] In view of the difficulty in focusing of the camera of the inspection device (not shown in the drawings) in the related art, when the inspection device of the embodiment of the present application needs to acquire or process an image of a preset position, the image acquisition system of the inspection device acquires the image of the preset position, or the image acquisition system processes the image of the preset position, so that the inspection device can inspect and / or treat the preset position. Among them, the image acquisition system acquires the image of the preset position through the second camera 333, and the second optical lens group 3331 of the second camera 333 moves under the drive of the driving mechanism to adjust the distance between the second optical lens 3331 and the second image sensor 3335, so that the second camera 333 can focus, thereby improving the quality of the image formed by the second camera 333.

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] An embodiment of the present application provides an inspection device, which includes: a shell (not shown in the drawings) and an image acquisition system, wherein the shell has a accommodating cavity, the image acquisition system is located in the accommodating cavity and is connected to the shell, and the image acquisition system includes: an image acquisition component 330 and a driving mechanism, the image acquisition component 330 includes a second camera 333, the second camera 333 includes a second optical lens group 3331 and a second image sensor 3335, and the driving mechanism is drivingly connected to the second optical lens group 3331 to drive the second optical lens group 3331 to move relative to the second image sensor 3335.

[0035] According to the inspection device of the embodiment of the present application, when the inspection device needs to acquire or process an image of a preset position, the image acquisition system of the inspection device acquires the image of the preset position, or the image acquisition system processes the image of the preset position, so that the inspection device inspects and / or treats the preset position. The image acquisition system acquires the image of the preset position through the second camera 333, and the second optical lens group 3331 of the second camera 333 moves under the drive of the driving mechanism to adjust the distance between the second optical lens and the second image sensor 3335, so that the second camera 333 can focus, thereby improving the quality of the image formed by the second camera 333.

[0036] The inspection device further includes an inspection system (not shown in the drawings), which is located in the accommodating cavity and connected to the housing, and the inspection device is configured to be electrically connected to the endoscope when the inspection device is mounted on the endoscope, so as to process the image of the first preset position acquired by the endoscope. The image acquisition system is configured to acquire an image of the second preset position, or acquire and process the image of the second preset position.

[0037] When the inspection device is installed in the endoscope, the inspection system can be electrically connected to the endoscope to process the image of the first preset position obtained by the endoscope. The image acquisition system can obtain the image of the second preset position, or obtain and process the image of the second preset position. Therefore, the inspection device of the embodiment of the present application can not only inspect and / or treat the first preset position, but also inspect and / or treat the second preset position, thereby increasing the function of the inspection device and expanding the scope of application of the inspection device. When performing multiple inspections and / or treatments on the first preset position and the second preset position, such as the ear, nose, throat, oral cavity, abdominal cavity, uterine cavity, vagina and other human cavities, as well as human body surfaces such as skin, various endoscopic inspection equipment can share the inspection device of the embodiment of the present application, reducing the number of components of the endoscopic inspection equipment, improving the portability of the endoscopic inspection equipment, and facilitating the coordinated integration of various endoscopic inspection equipment.

[0038] When the inspection device is installed with the dilator, the inspection device and the dilator cooperate with each other, and the image acquisition system of the inspection device can obtain images inside the vagina, thereby inspecting and / or treating the vagina. In this way, the number of parts of various endoscopic inspection equipment used in gynecological diagnosis and treatment can be reduced, and the convenience of carrying these endoscopic inspection devices is improved. Moreover, the coordinated integration of various endoscopic inspection equipment in gynecological diagnosis and treatment equipment can be achieved.

[0039] Exemplarily, the image acquisition system further includes a second mainboard (not shown in the drawings) and a light source assembly (not shown in the drawings). The second mainboard is connected to the housing, and an image acquisition circuit may be formed in the second mainboard to implement the image acquisition function of the image acquisition system for the second preset position.

[0040] The light emitting side of the light source assembly faces the light transmission window (not shown in the drawings) and is electrically connected to the second main board. The light emitting side of the light source assembly refers to the side where the light source assembly can emit light. When the light source assembly emits light, the light emitted by it can be irradiated to the second preset position through the light transmission window to illuminate the second preset position.

[0041] For example, a light absorbing layer may be provided on the edge of the light-transmitting protective sheet (not shown in the drawings) facing the light source assembly. When the light source assembly emits light, the light absorbing layer can absorb the light directed toward the edge of the light-transmitting protective sheet, preventing the light-transmitting protective sheet from reflecting the light and entering the image acquisition assembly 330 to form stray light, thereby improving the quality of the image formed by the image acquisition assembly 330.

[0042] The image acquisition component 330 is electrically connected to the second main board, and has a first light incident surface 3311, which is opposite to the light-transmitting window to receive external light. The image acquisition component 330 can acquire light from the second preset position through the light-transmitting window to image the second preset position.

[0043] The second main board can control the light source assembly to emit light. The light emitted by the light source assembly is irradiated to the second preset position through the light-transmitting window. The second preset position reflects the light emitted by the light source assembly to the image acquisition assembly 330. The image acquisition assembly 330 images the second preset position and then transmits the image of the second preset position to the second main board. The second main board processes the image of the second preset position, etc.

[0044] refer to Figure 1 The image acquisition component 330 further includes a beam splitter prism 331 and a first camera 332. The beam splitter prism 331 has a first light incident surface 3311. External light enters the beam splitter prism 331 through the first light incident surface 3311 and is split into a first light path A and a second light path B that are perpendicular to each other. For example, referring to Figure 2 , the beam splitter prism 331 may include two right-angle prisms whose oblique surfaces are attached to each other. One right-angle surface of one of the right-angle prisms is a first light incident surface 3311, and the other right-angle surface of the right-angle prism is a second light exit surface 3314, and the oblique surfaces attached to each other are a beam splitter surface 3312. One right-angle surface of the other right-angle prism is a first light exit surface 3313. External light can enter the beam splitter prism 331 through the first light incident surface 3311, and when incident on the beam splitter surface 3312, it is divided into a first light path A and a second light path B that are perpendicular to each other at the beam splitter surface 3312, the first light path A is emitted through the first light exit surface 3313, and the second light path B is emitted through the second light exit surface 3314.

[0045] The first camera 332 may be located on the first optical path A, and the first camera 332 is used to form an image with a first magnification. The second camera 333 may be located on the second optical path B, and the second camera 333 is used to form an image with a second magnification, and the second magnification may be greater than the first magnification. In this way, the image acquisition component 330 can acquire images with different magnifications, so as to facilitate the operator to inspect and / or treat the second preset position.

[0046] Exemplarily, along the extension direction of the first optical path A, the first camera 332 may include a first optical lens group (not shown in the drawings), a first dual-bandpass filter (not shown in the drawings) and a first image sensor (not shown in the drawings) in sequence. After entering the first optical lens group, the external light enters the first dual-bandpass filter, which filters the light, and the filtered light enters the first image sensor for imaging. For example, the first image sensor may be a complementary metal oxide semiconductor (CMOS) image sensor or a charge-coupled device (CCD) image sensor. The first dual-bandpass filter can filter the light entering the first camera 332, thereby improving the spectral accuracy of the light entering the first camera 332, and further improving the quality of the resulting image.

[0047] The driving mechanism may also include a first moving mechanism (not shown in the drawings), which is installed in the shell and connected to the first camera 332 to drive the first camera 332 to move along the first optical path A, thereby adjusting the position of the first camera 332 so that the first camera 332 can focus, thereby improving the quality of the image formed by the first camera 332.

[0048] The first moving mechanism may include a voice coil motor (VCM). The moving stroke provided by the voice coil motor for the second camera 333 may be greater than or equal to 0.2 mm.

[0049] Exemplarily, along the extension direction of the second optical path B, the second camera 333 may include a second optical lens group 3331, a second dual-bandpass filter 3332, and a second image sensor 3335 in sequence. After entering the second optical lens group 3331, the external light enters the second dual-bandpass filter 3332, and the second dual-bandpass filter 3332 filters the light, and the filtered light enters the second image sensor 3335 for imaging. For example, the second image sensor 3335 may be a CMOS image sensor or a CCD image sensor. The second dual-bandpass filter 3332 can filter the light entering the second camera 333, thereby improving the spectral accuracy of the light entering the second camera 333, and further improving the quality of the formed image.

[0050] For example, reference Figure 2, the second optical lens group 3331 of the second camera 333 can slide relative to the housing along the second optical path. Specifically, the driving mechanism includes a second moving mechanism 340, which is installed in the housing. The second moving mechanism 340 is drivingly connected to the second optical lens group 3331. The second moving mechanism 340 can drive the second optical lens group 3331 to move along the second optical path to adjust the distance between the second optical lens group 3331 and the second image sensor 3335 to achieve the purpose of focusing, ensuring that the second image sensor 3335 obtains a clear image, which is then transmitted to the image processing system, for example, the second mainboard, so as to realize image processing.

[0051] For example, reference Figure 2 The second camera 333 further includes a camera circuit board 3336, the second moving mechanism 340 is fixedly connected to the camera circuit board 3336, the second dual-bandpass filter 3332 is fixedly connected to the camera circuit board 3336, and the second image sensor 3335 is fixedly connected to the camera circuit board 3336, that is, the camera circuit board 3336 plays a role in fixing the second moving mechanism 340, the second dual-bandpass filter 3332 and the second image sensor 3335 to ensure the reliability of the second moving mechanism 340 and the second image sensor 3335. In addition, the second image sensor 3335 is electrically connected to the camera circuit board 3336, and the camera circuit board 3336 is electrically connected to the second main board. The second image sensor 3335 transmits a clear image to the camera circuit board 3336, and the camera circuit board 3336 transmits a clear image to the second main board, and the image is processed by the second main board.

[0052] The second camera 333 also includes a reinforcing plate 3337, which is fixedly connected to the camera circuit board 3336. Specifically, the reinforcing plate 3337 is arranged on a side of the camera circuit board 3336 away from the second optical lens group 3331 to reinforce the camera circuit board 3336 and ensure the firmness of the camera circuit board 3336.

[0053] For example, reference Figure 2The second moving mechanism 340 includes: a voice coil motor 341 and a connecting ring 342. The voice coil motor 341 is fixedly connected to the camera circuit board 3336. Specifically, the voice coil motor 341 is an annular structure. The first end of the annular voice coil motor 341 is fixedly connected to the camera circuit board 3336, and the second end of the annular voice coil motor 341 is drivingly connected to the connecting ring 342. The outer ring of the connecting ring 342 is threadedly connected to the inner ring of the voice coil motor 341. The connecting ring 342 can be rotated from the second end of the voice coil motor 341 to enter the interior of the voice coil motor 341, and at least part of the connecting ring 342 can be located inside the voice coil motor 341. The inner ring of the connecting ring 342 is connected to the second optical lens group 3331, and the outer thread of the connecting ring 342 is driven by the inner thread of the voice coil motor 341 to realize the movement of the connecting ring 342, and the connecting ring 342 drives the second optical lens group 3331 connected thereto to move, thereby achieving the purpose of adjusting the distance between the second optical lens group 3331 and the second image sensor 3335 to achieve the purpose of focusing. Further, the inner ring of the connecting ring 342 is detachably connected to the second optical lens group 3331, specifically, the inner thread of the inner ring of the connecting ring 342 cooperates with the outer thread of the outer ring of the second optical lens group 3331, so as to facilitate the assembly and disassembly of the connecting ring 342 and the second optical lens group 3331.

[0054] The second moving mechanism 340 may further include a guide rod (not shown in the drawings), which is arranged along the optical axis of the second camera, and the guide rod and the connecting ring 342 are relatively movable, and when the voice coil motor 341 drives the connecting ring 342 to rotate, the connecting ring 342 can move along the guide rod. Specifically, a sliding through hole (not shown in the drawings) is also arranged on the connecting ring, and the guide rod is slidably connected to the sliding through hole, and when the voice coil motor 341 drives the connecting ring 342 to rotate, the sliding through hole of the connecting ring 342 moves along the optical axis under the constraint of the guide rod.

[0055] For example, reference Figure 1 The image acquisition component 330 may further include a steering prism 334, which is located on the second optical path B and between the beam splitter prism 331 and the second camera 333. The steering prism 334 can change the direction of the second optical path B and fold the second optical path B to shorten the distance between the beam splitter prism 331 and the second camera 333, thereby reducing the space occupied by the image acquisition component 330, which is conducive to the miniaturization of the inspection device.
