[0093] In view of the technical problem that the inspection device in the related technology has a small scope of application, when conducting multiple inspections such as the uterine cavity and vagina, each endoscopic inspection equipment requires an inspection device, which leads to a large number of parts for various endoscopic inspection devices and is inconvenient to carry. The inventors have found that the reason is that the inspection device has a single function.

[0094] In view of this, the inspection device of the embodiment of the present application is provided with an inspection system and an image acquisition system. When the inspection device is installed in an endoscope, the inspection system can be electrically connected to the endoscope to process the image of the first preset position acquired by the endoscope; when the inspection device is not installed in the endoscope, the image acquisition system can acquire the image of the second preset position.

[0095] Therefore, the inspection device of the embodiment of the present application can inspect and / or treat the first preset position, and can also inspect and / or treat the second preset position, thereby expanding the scope of application of the inspection device. When inspecting the first preset position and the second preset position, such as the ears, nose and throat, oral cavity, abdominal cavity, uterine cavity, vagina and other human cavities, as well as human body surfaces such as skin, etc., various endoscopic inspection equipment can share the inspection device of the embodiment of the present application, reducing the number of components of various endoscopic inspection equipment, improving the portability of the endoscopic inspection device, and facilitating the coordinated integration of various endoscopic inspection equipment.

[0096] 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.

[0097] The embodiment of the present application provides an endoscopic inspection device, which may include an inspection device. The endoscopic inspection device may inspect and / or treat a first preset position. Figure 1 The endoscopic inspection device may further include an endoscope 20, and the inspection device 10 may be installed in the endoscope 20. For example, the inspection device 10 may be plugged into the endoscope 20 or screwed into the endoscope 20. The inspection device 10 is electrically connected to the endoscope 20 to inspect and / or treat the first preset position. The first preset position may be a human body cavity such as a uterine cavity, a nasal cavity, and an abdominal cavity.

[0098] The endoscope 20 refers to a visual medical device used to inspect and / or treat a human body cavity. For example, the endoscope 20 may be a hysteroscope, a nasal cavity scope, or a laparoscope. Figure 1 , the endoscope 20 may include a first operating handle 600, a mirror tube 610 and an endoscope circuit board (not shown in the drawings). The first operating handle 600 has a first accommodating cavity with an open bottom end, and the endoscope circuit board is installed in the first accommodating cavity. The mirror tube 610 is connected to the first operating handle 600. The inspection device 10 can be installed in the first accommodating cavity via the bottom end of the first operating handle 600. For example, the inspection device 10 can be inserted into the first accommodating cavity, or it can be screwed into the first accommodating cavity. The inspection device 10 is electrically connected to the endoscope circuit board.

[0099] When inspecting and / or treating the first preset position, the mirror tube 610 can be inserted into the first preset position. The mirror tube 610 can obtain an image of the first preset position and transmit the image to the inspection device 10 through the endoscope circuit board, thereby inspecting and / or treating the first preset position.

[0100] The endoscopic inspection device can also inspect and / or treat the second preset position. The second preset position can be an open human cavity such as the oral cavity, or an exposed human surface such as the skin. Exemplarily, when inspecting and / or treating the oral cavity, the inspection device 10 can be inserted into the open oral cavity, and the inspection device 10 can acquire and process images in the oral cavity, thereby inspecting the oral cavity. When inspecting the skin, the inspection device 10 can be placed opposite to the skin, thereby inspecting and / or treating the skin.

[0101] The second preset position may also be a human cavity with a closed opening, such as a vagina. Figure 2 In some possible implementations of the embodiments of the present application, the endoscopic inspection device may also include a dilator 30, and the inspection device 10 may be installed in the dilator 30. For example, the inspection device 10 may be inserted into the dilator 30, or may be screwed into the dilator 30.

[0102] The dilator 30 refers to a device that can be inserted into a human cavity with a closed opening, such as the vagina, to expand the space of the human cavity, thereby facilitating the inspection of the human cavity. Figure 2 , the expander 30 may include a second operating handle 700, a lower leaf 710 and an upper leaf 720. The second operating handle 700 has a second accommodating chamber with an open bottom end, and the top of the second operating handle 700 also has a visual window. The lower leaf 710 is located below the visual window and is connected to the second operating handle 700. The upper leaf 720 is located above the visual window and is rotatably connected to the second operating handle 700. The upper leaf 720 can rotate relative to the second operating handle 700 to open or close with the lower leaf 710. When the upper leaf 720 and the lower leaf 710 are opened, the visual window is exposed. When the upper leaf 720 and the lower leaf 710 are closed, the visual window is blocked. The inspection device 10 can be installed in the second accommodating chamber via the bottom end of the second operating handle 700. For example, the inspection device 10 can be inserted into the second accommodating chamber or can be screwed into the second accommodating chamber.

[0103] When inspecting and / or treating the second preset position, such as the vagina or other human body cavity, the upper leaf 720 can be controlled to rotate relative to the second operating handle 700, so as to close with the lower leaf 710. The closed upper leaf 720 and the lower leaf 710 are inserted into the second preset position, and then the upper leaf 720 is controlled to rotate in the opposite direction relative to the second operating handle 700, so as to open with the lower leaf 710 to expose the visual window and expand the space of the second preset position. The inspection device 10 can obtain an image of the second preset position through the exposed visual window, so as to inspect and / or treat the second preset position.

[0104] The inspection device 10 of the embodiment of the present application can inspect and / or treat the first preset position as well as the second preset position, thereby increasing the functionality of the inspection device 10 and expanding the scope of application of the inspection device 10. When performing multiple inspections and / or treatments of human cavities such as the ears, nose, throat, oral cavity, nasal cavity, abdominal cavity, uterine cavity, vagina, and human body surfaces such as the skin, various endoscopic inspection equipment can share the inspection device 10, reducing the number of overall components of all endoscopic inspection equipment and improving the portability of the endoscopic inspection device; and facilitating the coordinated integration of various endoscopic inspection equipment.

[0105] For example, in the process of gynecological diagnosis and treatment, the inspection device of the embodiment of the present application can be installed in a hysteroscope, so that the inspection device is electrically connected to the hysteroscope to form a uterine cavity inspection device with the hysteroscope. The inspection device of the embodiment of the present application can process the image of the uterine cavity obtained by the hysteroscope, so as to inspect and / or treat the uterine cavity. In addition, the inspection device of the embodiment of the present application can also be installed in a dilator to form a vaginal inspection device with the dilator. The inspection device of the embodiment of the present application cooperates with the dilator to obtain images in the vagina, so as to inspect and / or treat the vagina. In this way, the number of parts of various endoscopic inspection equipment used in the gynecological diagnosis and treatment process can be reduced, and the convenience of carrying these endoscopic inspection devices can be improved. Moreover, the coordinated integration of various endoscopic inspection equipment in gynecological diagnosis and treatment equipment can also be achieved.

[0106] refer to Figure 3 The inspection device 10 may include a housing 100, an inspection system 200, and an image acquisition system 300. The housing 100 has a receiving cavity.

Therefore, the inspection device 10 of the embodiment of the present application can inspect and / or treat the first preset position, and can also inspect and / or treat the second preset position, thereby increasing the function of the inspection device 10 and expanding the scope of application of the inspection device 10. When performing multiple inspections and / or treatments on the first preset position and the second preset position, such as the human body cavities such as the ear, nose and throat, oral cavity, abdominal cavity, uterine cavity, vagina, and human body surfaces such as skin, etc., various endoscopic inspection equipment can share the inspection device 10 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.

The inspection system 200 may have a first connection terminal 221, and the first connection terminal 221 is exposed by the first connection window 111. When the inspection device 10 is installed in the endoscope 20, the first connection terminal 221 may be electrically connected to the endoscope 20. Exemplarily, the first connection window 111 may be provided at the first end of the first housing 110. Figure 3 , the first connection terminal 221 may be a metal contact. Figure 4 , the first connection terminal 221 may also be a USB Type-C interface. It is understandable that the first connection terminal 221 may also be other types of connection terminals, which will not be described in detail in the embodiment of the present application.

[0112] The first end of the housing 100 may also be provided with a light-transmitting window 121, which is spaced apart from the first connecting window 111. The image acquisition system 300 located in the housing 100 may acquire an image of the second preset position through the light-transmitting window 121. Exemplarily, the light-transmitting window 121 may be provided at the first end of the second housing 120.

[0113] Exemplarily, a light-transmitting protective sheet 122 may be provided on the light-transmitting window 121, and the light-transmitting protective sheet 122 can protect the image acquisition system 300 located in the housing 100 to prevent the image acquisition system 300 from being contaminated. An anti-reflection film layer may also be provided on the protective sheet 122 to increase the amount of light entering the image acquisition system 300, thereby improving the quality of the image formed by the image acquisition system 300. A hydrophobic coating may also be provided on the side of the protective sheet 122 facing away from the accommodating cavity to prevent moisture, liquid, etc. from adhering to the light-transmitting protective sheet 122 and affecting the quality of the image acquired by the image acquisition system 300.

[0114] The first end of the housing 100 may include a first outer end face 130 and a second outer end face 140 connected to each other. The end face of the housing 100 provided with the first connection window 111 is the first outer end face 130, and the end face of the housing 100 provided with the light-transmitting window 121 is the second outer end face 140. There is a first angle α between the first outer end face 130 and the second outer end face 140, and the first angle α may be less than 180°. In this way, the light-transmitting window 121 and the first connection window 111 can face different directions, thereby avoiding mutual influence between the inspection system 200 and the image acquisition system 300.

[0115] refer to Figure 3 , a second angle β may be formed between the second outer end surface 140 of the housing 100 on which the light-transmitting window 121 is provided and the extension direction of the outer surface of the housing 100, and the second angle β may be greater than or equal to 10° and less than or equal to 45°. For example, the second angle β may be 10°, 15°, 20°, 25°, 30°, 35°, 40° or 45°. The second angle β within this range enables the housing 100 to be tilted when the inspection device 10 inspects and / or treats the second preset position, so that the operator can hold the inspection device 10. For example, when using the inspection device 10 to inspect and / or treat the human body surface such as skin, the operator needs to hold the housing 100 of the inspection device 10 so that the light-transmitting window 121 is opposite to the human body surface such as skin. Since the second outer end surface 140 of the housing 100 provided with the light-transmitting window 121 has a second angle β with the extension direction of the outer surface of the housing 100, there is a holding space between the housing 100 and the human body surface such as skin, which is convenient for the operator to hold. If the second angle β is too small or too large, the volume of the holding space will be reduced, reducing the comfort of the operator when holding, or the amount of light entering the image acquisition system 300 through the light-transmitting window 121 will be reduced, affecting the image quality.

[0116] The housing 100 may further include a connecting tube 150. A first connecting hole may be provided at the second end of the housing 100. The connecting tube 150 is covered on the first connecting hole. The connecting tube 150 is connected to the accommodating cavity through the first connecting hole. A connecting wire may be provided in the accommodating cavity. The connecting wire may be sequentially passed through the first connecting hole and the connecting tube to be electrically connected to external devices such as a display, a computer, and a surgical instrument.

[0117] The second end of the housing 100 may be provided with a second connection window, and the inspection system 200 may have a second connection terminal 231, which is exposed by the second connection window. The inspection system 200 in the housing 100 may be electrically connected to an external device through the second connection terminal 231 to perform signal transmission between the endoscope 20, the first mainboard 210 and the external device, for example, the image of the first preset position acquired by the endoscope 20 is processed by the inspection system 200 and transmitted to the external device.

The second connection circuit board 230 has a second connection terminal 231, which is used to be electrically connected to an external device. The external device may be a display, a computer, or a surgical instrument.

[0122] After the endoscope 20 acquires the image of the first preset position, the image of the first preset position can be transmitted to the first connection circuit board 220 through the first connection terminal 221, and then the image of the first preset position is transmitted to the first main board 210 for processing, and then transmitted to the second connection circuit board 230, and transmitted to the external device through the second connection terminal 231. In addition, the first main board 210 can also control the endoscope 20 and the external device through the first connection terminal 221 and the second connection terminal 231.

The second end of the housing 100 may be provided with a third connection window (not shown in the drawings), and the third connection window exposes the third connection terminal. The third connection terminal is used to electrically connect with surgical instruments such as laser knives. The third connection terminal electrically connects the surgical instrument to the first mainboard 210, so that the surgical instrument can perform a treatment operation under the control of the first control circuit of the first mainboard 210, so that the inspection device 10 of the embodiment of the present application has a treatment function, further increasing the function of the inspection device 10.

Exemplarily, a key window 112 may be provided on the side wall of the housing 100, and part of the key assembly 240 may extend out of the key window 112 to facilitate key operation of the key assembly 240.

[0125] For example, continue to refer to Fig.11The key assembly 240 may include a key switch 241, a key pressure plate 242, and a key board 243. The key switch 241 is located on the side of the first main board 210 facing the key window 112, and is electrically connected to the first main board 210. For example, the key switch 241 may be welded to the first main board 210. The first control circuit in the first main board 210 may be controlled by pressing a key on the key switch, thereby controlling the endoscope 20, external devices, etc. The key pressure plate 242 is located on the side of the first main board 210 facing the key window 112, and is connected to the housing 100. The key pressure plate 242 is provided with a key through hole 244, and the key through hole 244 is covered on the key switch 241.

The key groove 247 is sleeved on the key switch 241, and a portion of the key portion 245 extends out of the key window 112. In other words, the key portion 245 covers the key switch 241, which can protect the key switch 241, and the key switch 241 can be operated by pressing the key portion 245, thereby improving the convenience of key operation. The limiting portion 246 is located between the key pressing plate 242 and the housing 100. When the key pressing plate 242 is connected to the housing 100, the limiting portion 246 is fixed between the key pressing plate 242 and the housing 100, thereby improving the convenience of fixing the key plate 243.

[0126] The image acquisition system 300 is located in the housing 100. Figure 6 , Figure 7 and Figure 8 , the image acquisition system 300 may include a second mainboard 310, a light source assembly 320 and an image acquisition assembly 330. The second mainboard 310 is connected to the housing 100. An image acquisition circuit may be formed in the second mainboard 310 to realize the image acquisition function of the image acquisition system 300 for the second preset position. In some possible implementations of the embodiment of the present application, a second image processing circuit may also be formed in the second mainboard 310 to realize functions such as image processing of the image acquisition system 300. Exemplarily, the second mainboard 310 may have a second end facing the housing 100 and may be provided with a fourth connection terminal 311, and the fourth connection terminal 311 may be a power interface or a USB Type-C interface, etc. The fourth connection terminal 311 may be connected to an external device through a connection line inserted in the connection cylinder 150. It is understandable that the fourth connection terminal 311 may also be a connection terminal of other types, which will not be described in detail in the embodiment of the present application. The external device may be a display, a computer, a power supply or a surgical instrument, etc.

[0127] In some possible implementations of the embodiments of the present application, the second mainboard 310 may be electrically connected to the first mainboard 210. The second mainboard 310 may be controlled by the first control circuit in the first mainboard 210. For example, the first control circuit may be controlled by pressing a key on the key assembly 240, thereby controlling other components of the image acquisition system 300, such as the light source assembly 320 or the image acquisition assembly 330. For example, the second mainboard 310 may also transmit the image of the second preset position to the first image processing circuit of the first mainboard 210 for processing.

[0128] In some other possible implementations of the embodiment of the present application, the second mainboard 310 may have a second control circuit, and the second control circuit is used to control the image acquisition system 300 to automatically acquire and process the image of the second preset position. Exemplarily, the second mainboard 310 may also be connected to an external device through the fourth connection terminal 311 to control the second control circuit through the external device, or control the external device through the second control circuit.

[0129] Exemplarily, the housing 100 may be provided with an indicator light hole (not shown in the drawings). The inspection system 200 and / or the image acquisition system 300 may also be provided with a status indicator light and a light guide column, and the status indicator light is used to indicate the working status of the inspection system 200 and / or the image acquisition system 300. The light guide column is installed in the indicator light hole and connected to the indicator light. When the inspection system 200 and / or the image acquisition system 300 is working, the indicator light emits, and the light emitted by the indicator light is emitted from the indicator light hole of the housing 100 via the light guide column, so that the operator can confirm the working status of the inspection device 10 of the embodiment of the present application according to the state of the light emitted from the indicator light hole, thereby improving the convenience of operation of the inspection device 10.

[0130] The light emitting side of the light source assembly 320 faces the light transmission window 121 and is electrically connected to the second main board 310. The light emitting side of the light source assembly 320 refers to the side where the light source assembly 320 can emit light. When the light source assembly 320 emits light, the light emitted by it can irradiate the second preset position through the light transmission window 121 to illuminate the second preset position.

[0131] For example, a light absorbing layer may be provided on the edge of the light-transmitting protective sheet 122 facing the light source assembly 320. When the light source assembly 320 emits light, the light absorbing layer can absorb the light directed toward the edge of the light-transmitting protective sheet 122, preventing the light-transmitting protective sheet 122 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.

[0132] The image acquisition component 330 is electrically connected to the second main board 310, and has a first light incident surface 3311, which is opposite to the light-transmitting window 121 to receive external light. The image acquisition component 330 can acquire light from the second preset position through the light-transmitting window 121 to image the second preset position.

[0133] The second main board 310 can control the light source assembly 320 to emit light. The light emitted by the light source assembly 320 is irradiated to the second preset position through the light-transmitting window 121. The second preset position reflects the light emitted by the light source assembly 320 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 310. The second main board 310 processes the image of the second preset position, etc.

[0134] For example, reference Figures 5 to 8 , the light source assembly 320 may include a light source circuit board 321 and a plurality of light emitting devices 322. The light source circuit board 321 is connected to the housing 100. For example, the light source circuit board 321 may be indirectly connected to the housing 100 through a first mounting bracket 335. The light source circuit board 321 is electrically connected to the second main board 310 so as to be controlled by the second main board 310. The light source circuit board 321 may be electrically connected to the second main board 310 through an FFC or a harness. In some possible implementations of the present application, the light source circuit board 321 may be a flexible printed circuit (FPC), which may be directly welded to the second main board 310. The light source circuit board 321 may be provided with an avoidance hole 323, which surrounds at least part of the first light incident surface 3311 to prevent the light source circuit board 321 from blocking the first light incident surface 3311. A plurality of light emitting devices 322 are provided on the light source circuit board 321 to emit light under the action of the light source circuit board 321. Exemplarily, the light emitting device 322 may be a light emitting diode (LED for short).

[0135] The light emitted by the multiple light-emitting devices 322 may include at least one of white light, green light, purple light, infrared light and ultraviolet light to provide a variety of illumination spectra for the second preset position, so that the image acquisition component 330 can acquire images of different spectra of the second preset position, thereby enabling the inspection device 10 to perform different detections on the second preset position.

[0136] Exemplarily, the light emitted by the plurality of light emitting devices 322 may be white light, and the spectrum of the white light may be 420-680 nm. The plurality of light emitting devices 322 may provide white light illumination for the second preset position, and the image acquisition component 330 may acquire a white light image of the second preset position, so that the inspection device 10 may perform conventional white light detection on the second preset position.

[0137] Exemplarily, the light emitted by the plurality of light emitting devices 322 may include green light and purple light, and the central wavelength of the green light may be 540 nm. The central wavelength of the purple light emitted by the plurality of light emitting devices 322 may be 415 nm. The plurality of light emitting devices 322 may provide green light and purple light illumination for the second preset position, and the image acquisition component 330 may acquire green light and purple light images of the second preset position, so that the inspection device 10 may perform narrow band imaging (NBI) detection on the lower epidermal blood vessels and upper epidermal blood vessels of the second preset position.

[0138] Exemplarily, the light emitted by the plurality of light emitting devices 322 may be infrared light, and the central wavelength of the infrared light may be 780 nm. The plurality of light emitting devices 322 may provide infrared light for the second preset position to excite the target agent at the second preset position to emit fluorescence, and the image acquisition component 330 may acquire the target agent fluorescence image at the second preset position, so that the inspection device 10 may perform the target agent fluorescence detection on the second preset position.

[0139] Exemplarily, the light emitted by the plurality of light emitting devices 322 may be ultraviolet light, and the central wavelength of the ultraviolet light may be 340 nm. The plurality of light emitting devices 322 may provide ultraviolet light for the second preset position to excite the second preset position to emit fluorescence, and the image acquisition component 330 may acquire an autofluorescence image of the second preset position, so that the inspection device 10 may perform autofluorescence detection on the second preset position.

[0140] The image acquisition component 330 can acquire an image of the second preset position. Exemplarily, the image acquisition component 330 may include an imaging camera, which is installed in the housing 100, and the light incident surface of the imaging camera is opposite to the light transmission window 121 to receive external light for imaging.

[0141] In some possible implementations of the present application, reference is made to Figures 5 to 8 , the image acquisition component 330 may include a beam splitter prism 331, a first camera 332, and a second camera 333. 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 7 and Figure 8, 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.

[0142] Exemplarily, the ratio of the luminous flux between the first optical path A and the second optical path B may be 1:1. It is understandable that the ratio of the luminous flux between the first optical path A and the second optical path B may also be other values, such as 1:2, etc., which will not be described in detail in the embodiments of the present application.

[0143] 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.

[0144] Exemplarily, the focal length of the second camera 333 may be greater than the focal length of the first camera 332, so that the second magnification of the second camera 333 can be greater than the first magnification of the first camera 332. For example, the focal length of the second camera 333 may be 12 to 16 mm, and the focal length of the first camera 332 may be 3.6 to 4.7 mm.

[0145] The field of view of the second camera 333 may be smaller than the field of view of the first camera 332. For example, the field of view of the second camera 333 may be 40×30 mm, and the field of view of the first camera 332 may be 80×60 mm, so that the image acquisition component 330 can acquire images of different fields of view, thereby facilitating the operator to inspect and / or treat the second preset position.

[0146] Exemplarily, the number of pixels of the second camera 333 and the first camera 332 may be 5 mega pixels (MP for short).

[0147] Exemplarily, along the extension direction of the first optical path A, the first camera 332 may include a first optical lens group, a first dual-bandpass filter, and a first image sensor in sequence. After entering the first optical lens group, the external light enters the first dual-bandpass filter, and the first dual-bandpass filter 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.

[0148] The first dual-bandpass filter has a first filtering wavelength range and a second filtering wavelength range, the first filtering wavelength range may be 400-680 nm, and the second filtering wavelength range may be 810-830 nm. The first dual-bandpass filter may filter light within two wavelength ranges, without the need to set up two independent filters, thereby simplifying the mechanical structure of the first camera 332 and reducing the volume of the first camera 332, which is conducive to the miniaturization of the inspection device 10.

[0149] Exemplarily, along the extension direction of the second optical path B, the second camera 333 may include a second optical lens group, a second dual-bandpass filter, and a second image sensor in sequence. After entering the second optical lens group, the external light enters the second dual-bandpass filter, and the second dual-bandpass filter filters the light, and the filtered light enters the second image sensor for imaging. For example, the second image sensor may be a CMOS image sensor or a CCD image sensor. The second dual-bandpass filter 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 resulting image.

[0150] The second dual-bandpass filter has a third filtering wavelength range and a fourth filtering wavelength range, the third filtering wavelength range may be 400-680 nm, and the fourth filtering wavelength range may be 810-830 nm. The second dual-bandpass filter can filter light within two wavelength ranges without the need to set up two independent filters, thereby simplifying the mechanical structure of the second camera 333 and reducing the volume of the second camera 333, which is conducive to the miniaturization of the inspection device 10.

[0151] It should be noted that when the light emitted by the multiple light-emitting devices 322 is ultraviolet light, it can excite the second preset position to emit fluorescence. The fluorescence emitted by the second preset position usually has a wavelength range of 450 to 460 nm. Therefore, the fluorescence can enter the first camera 332 through the first dual-bandpass filter and enter the second camera 333 through the second dual-bandpass filter.

[0152] For example, reference Figures 5 to 8 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 10.

[0153] The turning prism 334 may include a second light incident surface 3341, a first light reflecting surface 3342, a second light reflecting surface 3343, and a third light exiting surface 3344. The second light incident surface 3341 is opposite to the second light exiting surface 3314. The first light reflecting surface 3342 is opposite to the second light incident surface 3341. The second light reflecting surface 3343 is opposite to the first light reflecting surface 3342 and is adjacent to the second light incident surface 3341. The third light exiting surface 3344 is located between the first light reflecting surface 3342 and the second light reflecting surface 3343.

[0154] The light emitted from the second light emitting surface 3314 enters the second light incident surface 3341 and is then reflected by the first light reflecting surface 3342 . The light is reflected to the second light reflecting surface 3343 , and then is reflected by the second light reflecting surface 3343 , emitted from the third light emitting surface 3344 , and enters the second camera 333 .

[0155] Exemplarily, the image acquisition component 330 may further include a first mounting frame 335, and the first mounting frame 335 is connected to the housing 100. For example, the first mounting frame 335 may be connected to the housing 100 by bolts. The beam splitter prism 331, the steering prism 334, the first camera 332, and the second camera 333 are all mounted on the first mounting frame 335. In the process of assembling and adjusting the image acquisition component 330, the orientation of the beam splitter prism 331, the steering prism 334, the first camera 332, and the second camera 333 may be adjusted by adjusting the structure of the first mounting frame 335, thereby improving the convenience of assembling and adjusting the image acquisition component 330.

[0156] The image acquisition system 300 may also include a first moving mechanism (not shown in the drawings), which is installed in the shell 100 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.

[0157] 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.

[0158] For example, reference Fig. 9 and Fig.11 , the second image sensor of the second camera 333 can slide along the second optical path relative to the housing 100. For example, the second camera 333 can also include a lens barrel 3336 and a base 3331, the lens barrel 3336 is used to install the second optical lens group, and is connected to the first mounting bracket 335. The base 3331 is provided with a mounting hole, the mounting hole cover is provided on the second image sensor 3335, and the base 3331 is connected to the second image sensor 3335. The mounting hole is also sleeved on the lens barrel 3336, so that the base 3331 can slide relative to the lens barrel 3336.

[0159] The image acquisition system 300 may also include a second moving mechanism 340, which is installed in the shell 100 and connected to the second image sensor 3335 of the second camera 333 to drive the second image sensor 3335 to move along the second optical path B, thereby adjusting the position of 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.

[0160] Exemplarily, the second moving mechanism 340 may include a second mounting frame 341, a transmission screw 342, a transmission nut 343, and a driving motor 344. The second mounting frame 341 is connected to the housing 100. For example, the second mounting frame 341 may include a connecting plate 3411 and two mounting plates 3412. The connecting plate 3411 may be connected to the first mounting frame 335 connected to the housing 100, and the two mounting plates 3412 are arranged at intervals along the optical axis direction of the second camera 333, and are both connected to the connecting plate 3411. The transmission screw 342 is arranged along the optical axis of the second camera 333, and both ends of the transmission screw 342 are rotatably connected to the second mounting frame 341. For example, both ends of the transmission screw 342 may be rotatably connected to the two mounting plates 3412, respectively. The transmission screw 342 is also connected to the driving motor 344. The transmission nut 343 is sleeved on the transmission screw 342 and is slidably connected to the second mounting bracket 341 along the optical axis of the second camera 333 . The transmission nut 343 is connected to the base 3331 connected to the second image sensor 3335 .

[0161] When the driving motor 344 is in operation, it can drive the transmission screw 342 to rotate relative to the second mounting frame 341. Since the transmission nut 343 is slidably connected to the second mounting frame 341 along the optical axis of the second camera 333, the transmission nut 343 slides on the transmission screw 342 along the optical axis of the second camera 333. The transmission nut 343 drives the second image sensor 3335 to slide along its optical axis, thereby adjusting the position of the second image sensor 3335.

[0162] The driving nut 343 may be directly connected to the second image sensor 3335 .

[0163] In some possible implementations of the present application, the transmission nut 343 may also be indirectly connected to the second image sensor 3335. Fig. 9 , the second moving mechanism 340 may further include a sliding rod 345 and a compression elastic member 346. The transmission nut 343 is provided with a sliding groove. The sliding rod 345 is arranged along the optical axis of the second camera 333, and the sliding rod 345 is slidably arranged in the sliding groove. The first end of the sliding rod 345 extending out of the sliding groove is provided with an abutment portion 3451, and the abutment portion 3451 abuts against the transmission nut 343. The second end of the sliding rod 345 is fixedly connected to the base 3331. For example, the base 3331 of the second camera 333 may be provided with a second connection hole 3332, and the second end of the sliding rod 345 may be inserted into the second connection hole 3332. The compression elastic member 346 is sleeved on the sliding rod 345, and the first end of the compression elastic member 346 abuts against the transmission nut 343, and the second end of the compression elastic member 346 abuts against the base 3331. Exemplarily, the compression elastic member 346 may be a compression spring.

[0164] The compression elastic member 346 is always in a compressed state, and applies thrust to the transmission nut 343 and the base 3331 respectively, so that the internal thread of the transmission nut 343 is always in contact with the thread groove wall of the transmission screw 342 away from the base 3331, and the abutment portion 3451 of the sliding rod 345 abuts against the transmission nut 343.

[0165] When the driving motor 344 is in motion, the driving motor 344 drives the transmission screw 342 to rotate, and the thread groove wall of the thread groove of the transmission screw 342 away from the base 3331 pushes the transmission nut 343, so that the transmission nut 343 moves toward the light-transmitting window 121. The transmission nut 343 pushes the abutment portion 3451, so that the sliding rod 345 drives the base 3331 and the second image sensor to move toward the second optical lens group.

[0166] When the driving motor 344 moves in the reverse direction, the driving motor 344 drives the transmission screw 342 to rotate in the reverse direction, and the thread groove wall of the thread groove of the transmission screw 342 away from the base 3331 pushes the transmission nut 343, so that the transmission nut 343 moves in the direction away from the light transmission window 121. The transmission nut 343 slides relative to the sliding rod 345 to compress the compression elastic member 346, and the compression elastic member 346 applies a thrust to the transmission nut 343 and the base 3331, so that the internal thread of the transmission nut 343 is always in contact with the thread groove wall of the thread groove of the transmission screw 342 away from the base 3331, and the abutting portion 3451 of the sliding rod 345 abuts against the transmission nut 343, so that the sliding rod 345, the base 3331 and the second image sensor follow the transmission nut 343 to move in the direction away from the second optical lens group.

[0167] During the process of the transmission nut 343 moving relative to the transmission screw 342 in the direction of the light-transmitting window 121, and during the process of the transmission nut 343 moving relative to the transmission screw 342 in the direction away from the light-transmitting window 121, the working surfaces of the transmission nut 343 and the transmission screw 342 always maintain one-sided contact, thereby avoiding the transmission screw 342 from returning due to the gap between the external thread of the transmission screw 342 and the internal thread of the transmission nut when the transmission screw 342 changes its rotation direction, thereby improving the transmission accuracy between the transmission screw 342 and the transmission nut 343, and further improving the adjustment accuracy when adjusting the displacement of the second image sensor.

[0168] The second moving mechanism 340 may further include a guide rod 347, and the transmission nut 343 may be slidably connected to the second mounting bracket 341 via the guide rod 347. Fig. 9The guide rod 347 can be arranged along the optical axis of the second camera 333, and both ends of the guide rod 347 are connected to the second mounting frame 341. For example, both ends of the guide rod 347 can be fixedly connected to the two mounting plates 3412 respectively. The transmission nut 343 is provided with a sliding through hole 3431, and the sliding through hole 3431 is sleeved on the guide rod 347. The guide rod 347 can guide the transmission nut 343 along the optical axis of the second camera 333 to improve the movement accuracy of the transmission nut 343, thereby improving the position adjustment accuracy of the second camera 333.

[0169] refer to Fig.10 The second moving mechanism 340 may further include a first travel switch and a second travel switch 348 spaced apart along the optical axis direction of the second camera 333, and the first travel switch and the second travel switch 348 are both connected to the housing 100. Exemplarily, the first travel switch is connected to the first mounting bracket 335. The second travel switch 348 is connected to the first mounting bracket 335 through a connecting bracket 349, and the second travel switch 348 is arranged opposite to the first travel switch. The first travel switch and the second travel switch 348 are both electrically connected to the second main board 310. The second image sensor 3335 is connected to an indicator ring 3333. For example, the indicator ring 3333 may be connected to the base 3331, and the indicator ring 3333 has an indicator protrusion 3334, and the indicator protrusion 3334 is located between the first travel switch and the second travel switch 348.

[0170] When the second image sensor 3335 moves, the second image sensor 3335 drives the indicator ring 3333 to move, and when the indicator protrusion 3334 of the indicator ring 3333 contacts the first travel switch, it indicates that the second image sensor 3335 moves to the first position. When the indicator protrusion 3334 of the indicator ring 3333 contacts the second travel switch 348, it indicates that the second image sensor 3335 moves to the second position. The first travel switch and the second travel switch 348 send signals to the second main board 310 indicating whether they are triggered, so that the second main board 310 can know the position of the second image sensor 3335. The second main board 310 can control the driving motor according to the position of the second image sensor 3335, thereby automatically controlling the position of the second image sensor 3335, and then realizing automatic focusing of the second camera 333.

[0171] The inspection device 10 may further include a distance measuring system electrically connected to the second mainboard 310 to measure the distance of the second preset position. The distance measuring system may be located in the accommodating cavity and connected to the housing 100. The distance measuring system faces the light-transmitting window 121, and the distance measuring system is configured to measure the distance of the second preset position through the light-transmitting window 121. In some possible implementations of the embodiments of the present application, the first camera 332 and the second camera 333 may be adjusted according to the distance of the second preset position measured by the distance measuring system to realize the automatic focusing function.

[0172] For example, reference Figure 8 The distance measuring system may include a laser distance measuring sensor 400 or an infrared distance sensor. Taking the laser distance measuring sensor 400 as an example, the laser distance measuring sensor 400 may be installed on the side of the steering prism 334 facing the light transmission window 121, and may be electrically connected to the second main board 310 via an FFC or a harness. The laser distance measuring sensor 400 may emit a laser to the second preset position through the light transmission window 121, and receive the laser reflected by the second preset position, thereby measuring the distance to the second preset position.
