[0029] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0030] like Figure 1 As shown, in one embodiment, an endoscope device is provided, which includes a lens module (not shown) and a camera structure 10 having a light splitting element, and the lens module can inject a light beam into the camera structure 10 to achieve optical path connection. In addition, the camera structure 10 can achieve modular design, and the assembly is simple and convenient.

[0031] It should be noted that the lens module may include components such as an optical adapter, which may be an existing device and will not be described in detail here.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, a camera structure 10 with a spectroscopic element is provided, including a mounting base 100, a fixing base 200, a spectroscopic element 300 and a sensor module (not labeled).

[0033] like Figure 3 As shown, the mounting base 100 is provided with a first light passage 110 and a first mounting groove 120 which are interconnected, and the first mounting groove 120 is arranged on the light output side of the first light passage 110, that is, the light beam first passes through the first light passage 110 and then passes through the first mounting groove 120.

[0034] The lens module can be connected to a side of the mounting base 100 corresponding to the first light passage 110 by means of snap connection or screw connection, and the lens module can allow the light beam to be incident on the first light passage 110 and then incident on the first mounting groove 120 .

[0035] like Figure 3 As shown, optionally, the first light passage 110 and the first mounting groove 120 can extend along the axial direction of the mounting seat 100 .

[0036] like Figure 2 and Figure 4As shown, the fixing seat 200 is provided with a second light-transmitting channel 210 and a second mounting groove 220 which are interconnected, and the second mounting groove 220 is arranged at the light-entering side of the second light-transmitting channel 210, that is, the light beam first passes through the second mounting groove 220, and then passes through the second light-transmitting channel 210. At the same time, the front side of the fixing seat 200 is assembled and connected with the mounting seat 100 by bonding or other means, so that the first mounting groove 120 is connected with the second mounting groove 220 to form a mounting cavity 400, and one side of the fixing seat 200 is spaced apart from the mounting seat 100 to form a third light-transmitting channel 500 which is connected with the mounting cavity 400.

[0037] Optionally, the side of the fixing base 200 may be one of the bottom side, the top side, the proximal side or the distal side of the fixing base 200. Specifically in this embodiment, the side of the fixing base 200 refers to the bottom side of the fixing base 200.

[0038] Specifically, a gap formed between the inner wall of the fixing seat 200 and the inner wall of the mounting seat 100 forms a third light passage 500 communicating with the mounting cavity 400 .

[0039] Optionally, the second light passage 210 and the second mounting groove 220 may extend along the axial direction of the fixing base 200, and the first light passage 110, the first mounting groove 120, the second mounting groove 220 and the second light passage 210 are sequentially connected and on the same central axis.

[0040] The light splitting element 300 may be a light splitting prism or other device having a light splitting function. Figure 2 As shown, the beam splitter element 300 is disposed in the mounting cavity 400, and the light beam splitter element 300 can split the light beam emitted from the light exiting side of the first light passage 110 into the first light beam incident into the second light passage 210 (such as Figure 2 B) and the second light incident on the third light channel 500 (as shown in FIG. Figure 2 as shown in C).

[0041] Among them, the size and outline of the spectrometer element 300 can match the size and outline of the mounting cavity 400 to prevent the spectrometer element 300 from moving relative to the mounting seat 100 or the fixing seat 200, ensuring that the first light can be incident on the second light channel 210 and the second light can be incident on the third light channel 500.

[0042] Specifically, under the spectroscopic effect of the spectroscopic element 300, the light beam can be divided into two light beams (a first light beam and a second light beam). As an optional implementation, one light beam is white light and the other light beam is infrared light or near-infrared light, thereby achieving an infrared blood-penetrating and fog-penetrating effect or a fluorescent imaging effect.

[0043] like Figure 2 As shown, the sensor module includes a first sensor 610 and a second sensor 620. Furthermore, the first sensor 610 is arranged corresponding to the second light passage 210, and the second sensor 620 is arranged corresponding to the third light passage 500. In this way, the first light emitted from the second light passage 210 can be detected as an optical signal by the first sensor 610, and the second light emitted from the third light passage 500 can be detected as an optical signal by the second sensor 620. Since the central axis of the third light passage 500 is arranged at an angle to the central axis of the second light passage 210, two sensors can be used to realize multi-directional collection of optical signals.

[0044] Optionally, both the first sensor 610 and the second sensor 620 may be CMOS (Complementary Metal-Oxide-Semiconductor) sensors, which are smaller in size, thereby making the external size of the camera structure 10 smaller.

[0045] When assembling the camera structure 10 with a spectroscopic element in the above-mentioned embodiment, one side of the spectroscopic element 300 can be first installed in the first mounting groove 120 of the mounting seat 100, and then the fixing seat 200 is connected to the mounting seat 100, so that the other side of the spectroscopic element 300 is installed in the second mounting groove 220 of the fixing seat 200, and then the spectroscopic element 300 is completely installed in the mounting cavity 400 formed by connecting the first mounting groove 120 and the second mounting groove 220, and then the first sensor 610 is installed corresponding to the second light channel 210, and the second sensor 620 is installed corresponding to the third light channel 500, so that the modular design of each component can be realized, and the assembly is simple and convenient, and the assembly difficulty is low.

[0046] Specifically, the light beam emitted by the lens module passes through the first light channel 110 and is emitted to the beam splitter 300. The beam splitter 300 splits the light beam into a first light beam and a second light beam with different emission directions. The first light beam can be detected as an optical signal by the first sensor 610, and the second light beam can be detected as an optical signal by the second sensor 620, thereby realizing multi-directional collection of optical signals. One of the first light beam and the second light beam is white light, and the other is infrared light or near-infrared light, achieving infrared blood-penetrating and fog-penetrating effects and fluorescent imaging effects.

[0047] Optionally, the first sensor 610 is plugged into and matched with the second light passage 210 to ensure stability and convenience of assembly of the first sensor 610 .

[0048] like Figure 2As shown, in one embodiment, a first guide portion 211 is provided on a side wall of the second light passage 210 that is away from the second mounting groove 220, and the first guide portion 211 is guided and matched with the first sensor 610. In this way, the first guide portion 211 can guide the assembly between the first sensor 610 and the second light passage 210, thereby improving the assembly accuracy and reducing the assembly difficulty.

[0049] The first guide portion 211 may be a guide inclined surface or a guide curved surface.

[0050] Optionally, the second sensor 620 is plugged into and matched with the third light passage 500 to ensure the stability and convenience of assembling the second sensor 620 .

[0051] like Figure 4 As shown, in one embodiment, the side wall of the third light passage 500 surrounded by the fixing seat 200 is provided with a second guide portion 230, and the second guide portion 230 is guided and matched with the second sensor 620. In this way, the second guide portion 230 can guide the assembly between the second sensor 620 and the third light passage 500, thereby improving the assembly accuracy and reducing the assembly difficulty.

[0052] The second guide portion 230 may be a guide inclined surface or a guide curved surface.

[0053] like Figure 2 As shown, in addition, the camera structure 10 with a light splitting element further includes a protective member 700. The protective member 700 is disposed in the first light-through channel 110, so that the light splitting element 300 located in the mounting cavity 400 is isolated from the outside by the protective member 700 to prevent the outside from interfering with the light splitting element 300. Moreover, the protective member 700 is provided with a light-transmitting portion corresponding to the light splitting element 300, so that the light beam can normally pass through the first light-through channel 110 and be emitted to the light splitting element 300 without causing any influence or interference.

[0054] The protective member 700 may be in a sheet-like structure, and may be packaged in the first light passage 110 by bonding or other methods. The light-transmitting portion may be made of a light-transmitting material, for example, the entire protective member 700 is light-transmitting glass.

[0055] The angle between the central axis of the third light passage 500 and the central axis of the second light passage 210 can be flexibly adjusted according to actual processing conditions or usage requirements.

[0056] like Figure 2As shown, in one embodiment, the third light passage 500 is located at the bottom side of the fixing base 200, so that the second light is emitted from the bottom side of the fixing base 200, and the central axis of the third light passage 500 is perpendicular to the central axis of the second light passage 210. In this way, the light splitting element 300 divides the light beam into a first light beam and a second light beam that are perpendicular to each other, which can avoid interference or interference between the first light beam and the second light beam, and also makes the arrangement directions of the first sensor 610 and the second sensor 620 perpendicular to each other, which is convenient for the layout of the first sensor 610 and the second sensor 620, simplifies the installation space, and is conducive to miniaturization design.

[0057] Of course, in other embodiments, the central axis of the third light passage 500 and the central axis of the second light passage 210 may also be at other angles.

[0058] like Figure 2 As shown, in addition, the camera structure 10 with a light splitting element further includes a housing 800, the housing 800 is provided with a mounting channel, the mounting seat 100 is partially disposed in the mounting channel and is sealed with the housing 800. In this way, the lens module can be connected and assembled with the portion of the mounting seat 100 protruding from the mounting channel, and the sealing cooperation between the mounting seat 100 and the housing 800 can prevent foreign objects from entering the mounting channel and causing interference and influence on the internal components.

[0059] Furthermore, the fixing base 200, the light splitting element 300 and the sensor module are all installed in the installation channel.

[0060] It should be noted that the camera structure 10 also includes components such as a key module installed on the housing 800. Since these components may belong to the prior art, they will not be described in detail here.

[0061] The sealing fit can be achieved by injecting filling material or the like.

[0062] like Figure 2 As shown, optionally, the camera structure 10 with a spectroscopic element further includes a sealing ring 900, and the sealing ring 900 is disposed between the housing 800 and the mounting seat 100 so that the portion of the mounting seat 100 located in the mounting cavity 400 is sealed and matched with the housing 800. In this way, when the mounting seat 100 and the housing 800 are packaged, the gap between the mounting seat 100 and the housing 800 is filled by extrusion and deformation between the sealing ring 900, the mounting seat 100 and the housing 800, thereby achieving a good sealing effect. Moreover, the packaging can be achieved by simply installing the sealing ring 900 in the corresponding annular groove, which is simple and convenient. Among them, corresponding annular grooves can be opened at corresponding positions on the mounting seat 100 and / or the housing 800.

[0063] like Figure 2 As shown, in one embodiment, the camera structure 10 with a light splitting element further includes a shielding sleeve 1000, which is sleeved on the outside of the fixing seat 200, and the sensor module is arranged in the shielding sleeve 1000. In this way, the shielding sleeve 1000 can shield external signals, thereby preventing external signals from interfering with or affecting the signal collection and transmission of the sensor module, thereby ensuring the accuracy of the collection results.

[0064] The shielding sleeve 1000 may be made of a material with shielding properties such as metal.

[0065] like Figure 2 As shown, further, the shielding sleeve 1000 is provided with a bending portion 1100 at one end facing the mounting seat 100, and the bending portion 1100 is in conflict with the mounting seat 100. In this way, when the shielding sleeve 1000 is sleeved on the outer side of the fixing seat 200, the shielding sleeve 1000 can be pushed along the axial direction of the fixing seat 200 until the bending portion 1100 conflicts with the mounting seat 100 and cannot be pushed, and it can be determined that the shielding sleeve 1000 is installed in place, thereby improving the assembly accuracy and reducing the assembly difficulty.

[0066] The bending portion 1100 may be in the form of a flange or a flanging, and the bending portion 1100 may be integrally formed with the shielding sleeve 1000 or may be formed separately.

[0067] It should be noted that "some body" or "some part" can be a part of the corresponding "component", that is, "some body" or "some part" can be integrally formed with the "other parts of the component"; it can also be an independent component that can be separated from the "other parts of the component", that is, "some body" or "some part" can be manufactured independently and then combined with the "other parts of the component" into a whole.

As long as it contains the above-mentioned features and has the same function, it should be understood as an equivalent technical solution of this application.

[0068] It should be noted that the components included in the "unit", "assembly", "mechanism" and "device" of this application can also be flexibly combined, that is, modular production can be carried out according to actual needs to facilitate modular assembly.

As long as the above components are included and have the same functions, it should be understood that it is an equivalent technical solution of this application.
