[0002] An endoscope is a medical device that can be inserted into the body cavity and organ cavity for direct observation, diagnosis, and treatment. With the continuous development of technology, more and more optical imaging solutions are applied to endoscopes, such as polarized light imaging, infrared imaging, etc., which requires different sensors to receive corresponding optical signals. At present, some endoscopes divide the light beam of the optical lens into two paths of light by setting a beam splitter prism or other beam splitting elements in the camera structure and emit them to two sensors for optical signal detection. However, when the beam splitter prism is assembled, due to the influence of processing errors, it is easy to have problems of unstable assembly or inability to assemble. Utility Model Content

[0009] The technical solution is further described below:

[0010] In one embodiment, the interference element is threadedly connected to the mounting seat, so that the interference element can move relative to the mounting seat along the axial direction of the light passage to interfere with the light splitting element.

[0013] In one embodiment, the seat body is further provided with a supporting portion, which is arranged opposite to the interference portion and cooperates with the circumferential side wall of the light splitting portion. The extension height of the supporting portion relative to the sleeve body matches the difference between the outer diameter of the light guiding portion and the outer diameter of the light splitting portion.

[0014] In one embodiment, the diffractive camera structure further includes a first sensor element and a second sensor element, wherein the first sensor element is arranged at a light exit side corresponding to the first light hole to detect an optical signal of the first light, and the second sensor element is arranged at a light exit side corresponding to the second light hole to detect an optical signal of the second light.

[0015] In one of the embodiments, the light-splitting camera structure further includes a shielding sleeve, which is disposed on the outside of the sleeve body, and the first sensor element and the second sensor element are both disposed in the shielding sleeve.

Moreover, after the splitting element is stably and reliably assembled, the splitting element can split the light beam incident into the light passage into a first light beam and a second light beam, so that the first light beam is accurately emitted to the first light hole, and the second light beam is accurately emitted to the second light hole, so as to avoid the splitting element moving relative to the mounting seat, resulting in the light beam being unable to accurately emit to the corresponding light hole and affecting the collection of optical signals. At the same time, the modular design of the mounting seat, the splitting element and the abutment element can be realized, which reduces the difficulty of assembly and facilitates installation and assembly.

DETAILED DESCRIPTION

[0028] 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.

[0029] like Figure 1 As shown, in one embodiment, an endoscopic device is provided, which includes an optical lens (not shown) and a diffractive camera structure (not labeled). The optical lens can inject a light beam into the diffractive camera structure to achieve optical path connectivity.

[0030] It should be noted that the optical lens may include components such as an optical adapter, which may be existing devices and will not be described in detail here.

[0031] In a traditional camera structure capable of splitting light, the splitter element 300 is encapsulated in a mounting cavity, which is affected by processing errors and assembly errors. When the mounting cavity of the splitter element 300 is larger, the splitter element 300 may be unstable in assembly. When the mounting cavity of the splitter element 300 is smaller, the splitter element 300 may be unable to be assembled.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, a camera structure capable of splitting light is provided, including a mounting base 100 , an abutting element 200 and a splitting element 300 .

[0033] like Figures 1 to 3As shown, the mounting base 100 is provided with a light passage 110 extending in the axial direction, and the peripheral side wall of the mounting base 100 is provided with a first light hole 120 connected to the light passage 110, so that the central axis of the light passage 110 is arranged at an angle with the central axis of the first light hole 120, for example, vertically arranged. In addition, the inner side wall of the light passage 110 is provided with a resistance portion 130.

[0034] Optionally, the peripheral side wall of the mounting seat 100 may be a bottom side wall, an upper side wall, a proximal side wall or a distal side wall, and in this embodiment, the bottom side wall is preferred.

[0035] Optionally, the abutment portion 130 is in the form of an abutment protrusion, which extends radially along the light passage 110 , and the abutment protrusion does not affect the normal transmission of the light beam along the axial direction of the mounting seat 100 .

[0036] The optical lens may be connected to one side of the mounting base 100 by means of a snap connection or a screw connection, and the optical lens may inject a light beam into the light passage 110 along the axial direction of the light passage 110 .

[0037] like Figure 1 and Figure 2 As shown, the interference element 200 is disposed in the light passage 110. Furthermore, the interference element 200 is movably connected to the mounting seat 100, and the interference element 200 can reciprocate relative to the mounting seat 100 along the axial direction of the light passage 110. Moreover, the interference element 200 is provided with a second light hole 210 connected to the light passage 110, so that light can pass through the second light hole 210.

[0038] Optionally, a central axis of the second light through hole 210 overlaps with a central axial line of the light through channel 110 .

[0039] The resisting element 200 may be in a ring-shaped structure. The resisting element 200 may be in the form of an annular locking ring.

[0040] like Figure 1 and Figure 2 As shown, the beam splitter element 300 is disposed in the light passage 110. Furthermore, the beam splitter element 300 is located between the interfering element 200 and the interfering portion 130. The beam splitter element 300 is in interfering cooperation with the interfering portion 130 and the interfering element 200 on opposite sides of the axial direction of the light passage 110, respectively. For example, the interfering portion 130 is located on the left side of the beam splitter element 300 and is in interfering cooperation with the left side of the beam splitter element 300. The interfering element 200 is located on the right side of the beam splitter element 300 and can be moved relative to the mounting seat 100 to be in interfering cooperation with the right side of the beam splitter element 300. Furthermore, the beam splitter element 300 is used to split the light beam incident into the light passage 110 into a first light beam (such as Figure 1 and Figure 2A) and the second light (as shown in Figure 1 and Figure 2 As shown in FIG. 1B , the first light is emitted to the first light through hole 120 , and the second light is emitted to the second light through hole 210 .

[0041] Optionally, under the spectroscopic effect of the spectroscopic element 300, the light beam can be divided into two mutually perpendicular light beams (a first light beam and a second light beam), one of which is white light and the other is infrared light or near-infrared light, thereby achieving infrared blood-penetrating and fog-penetrating effects and fluorescent imaging effects.

[0042] The light splitting element 300 may be a light splitting prism or other device having light splitting function.

[0043] When assembling the spectroscopic element 300 of the spectroscopic camera structure of the above-mentioned embodiment, it is only necessary to place the spectroscopic element 300 in the light-through channel 110 of the mounting seat 100 so that one side of the spectroscopic element 300 is in contact with the interference portion 130, and then the interference element 200 is movably connected to the mounting seat 100 from the side away from the interference portion 130. By adjusting the position of the interference element 200 relative to the mounting seat 100, the interference element 200 is moved along the axial direction of the light-through channel 110 toward the direction close to the spectroscopic element 300 until it is in contact with the other side of the spectroscopic element 300, and then the spectroscopic element 300 is stably and reliably installed in the light-through channel 110 without the problem of unstable assembly or inability to assemble. Furthermore, after the spectroscopic element 300 is stably and reliably assembled, the spectroscopic element 300 can split the light beam incident into the light passage 110 into a first light beam and a second light beam, so that the first light beam is accurately emitted to the first light hole 120, and the second light beam is accurately emitted to the second light hole 210, thereby preventing the spectroscopic element 300 from moving relative to the mounting base 100, causing the light beam (the first light beam or the second light beam) to be unable to accurately emit to the corresponding light hole (the first light hole 120 or the second light hole 210), thereby affecting the collection of optical signals. At the same time, the modular design of the mounting base 100, the spectroscopic element 300, and the interference element 200 can be realized, reducing the difficulty of assembly and facilitating installation and assembly.

[0044] The movable connection between the abutment element 200 and the mounting seat 100 can be achieved by plug-in fitting or threaded connection, as long as the abutment element 200 can reciprocate axially relative to the mounting seat 100 along the light passage 110 .

[0045] In one embodiment, the interference element 200 is threadedly connected to the mounting seat 100, so that the interference element 200 can move relative to the mounting seat 100 along the axial direction of the light passage 110 until it interferes with the light splitting element 300. In this way, the threaded connection method allows the interference element 200 to move relative to the mounting seat 100 by at least one pitch, and the position of the interference element 200 relative to the mounting seat 100 is adjusted more accurately, so that the interference element 200 can apply a suitable interference force to the light splitting element 300, ensuring that the light splitting element 300 is not damaged by an excessively large interference force, nor is it moved relative to the mounting seat 100 by an excessively small interference force.

[0046] Specifically, the outer wall of the interference element 200 is provided with an external thread, and the inner wall of the light-through channel 110 is provided with an internal thread. The threaded connection between the light-through external thread and the internal thread enables the interference element 200 to reciprocate axially along the light-through channel 110 relative to the mounting seat 100.

[0047] like Figure 1 As shown, in addition, the camera structure capable of splitting light further includes a housing 800, and the mounting seat 100 is partially disposed in the housing 800 and is sealed with the housing 800 by means of a light-transmitting sealing ring or the like, so as to prevent foreign matter from entering the housing 800 and interfering with or affecting the operation of the internal components. Furthermore, the portion of the mounting seat 100 protruding from the housing 800 can be connected to the optical lens by means of a snap connection or a screw connection or the like.

[0048] like Figures 1 to 3As shown, in one embodiment, the mounting seat 100 includes a seat body 140 and a sleeve body 150 connected to each other. The outer diameter of the sleeve body 150 is smaller than the outer diameter of the seat body 140, so as to facilitate the assembly and connection of the mounting seat 100 and the housing 800. The sleeve body 150 is arranged on the light-emitting side of the seat body 140, that is, the light beam entering the light-passing channel 110 first passes through the seat body 140 and then passes through the sleeve body 150. In addition, the seat body 140 is provided with a first communication cavity 141 and a resistance part 130, and the sleeve body 150 is provided with a second communication cavity 151 and a first light-passing hole 120 connected with the second communication cavity 151, and the inner diameter of the second communication cavity 151 is larger than the inner diameter of the first communication cavity 141. In addition, the first communication cavity 141 and the second communication cavity 151 are connected to each other to form the light-passing channel 110, and the resistance element 200 is arranged in the second communication cavity 151 and is movably connected with the sleeve body 150. In this way, when assembling the spectrometer element 300, the spectrometer element 300 is inserted from the second connecting cavity 151 so that one side of the spectrometer element 300 is in contact with the interference portion 130, and then the interference element 200 is moved from the second connecting cavity 151 along the axial direction of the light-transmitting channel 110 toward the spectrometer element 300 until it is in contact with the other side of the spectrometer element 300, thereby stably and reliably installing the spectrometer element 300 in the light-transmitting channel 110, and there will be no problems with unstable assembly or inability to assemble.

[0049] Specifically, the base 140 is partially disposed in the housing 800 and sealed with the housing 800 by means of a light-transmitting sealing ring, and the sleeve 150 is completely disposed in the housing 800. The light beam emitted by the optical lens first enters the first connecting cavity 141 and then enters the second connecting cavity 151.

[0050] Optionally, the seat body 140 and the sleeve body 150 are integrally formed to save processing costs.

[0051] like Figure 1 , Figure 2 and Figure 4As shown, further, the light splitting element 300 includes a light splitting part 310 and a light guiding part 320 connected to each other, and the light guiding part 320 is arranged on the light emitting side of the light splitting part 310, that is, the light beam entering the light passage 110 first passes through the light splitting part 310 and then passes through the light guiding part 320. Among them, the outer diameter of the light guiding part 320 is larger than the outer diameter of the light splitting part 310, and the side of the light splitting part 310 away from the light guiding part 320 is arranged in the first connecting cavity 141 and abuts against the abutting part 130, and the outer side wall of the light splitting part 310 close to the light guiding part 320 is arranged with a relative interval with the first light through hole 120. The light guiding part 320 abuts against the circumferential side wall of the second connecting cavity 151 and abuts against the abutting element 200. In this way, the abutting portion 130 abuts against the light splitting portion 310, and the abutting element 200 moves along the axial direction of the light passage 110 toward the light guide portion 320 until it abuts against the light guide portion 320, thereby stably and reliably installing the light splitting element 300 in the light passage 110, without the problem of unstable assembly or inability to assemble. In addition, the light splitting portion 310 splits the light beam incident into the light passage 110 into a first light beam and a second light beam emitted in two different directions, the first light beam is emitted to the first light hole 120, and the second light beam passes through the light guide portion 320 and then is emitted to the second light hole 210 of the abutting element 200. Moreover, since the outer diameter of the light-guiding portion 320 is larger than the outer diameter of the light-splitting portion 310, and the inner diameter of the first connecting cavity 141 is smaller than the inner diameter of the second connecting cavity 151, when assembling the light-splitting element 300, only one end of the light-splitting portion 310 can be inserted into the second connecting cavity 151 first until the side of the light-splitting portion 310 away from the light-guiding portion 320 abuts against the interference portion 130. It is impossible to insert one end of the light-guiding portion 320 into the second connecting cavity 151 first and abut against the interference portion 130, which can play a role in fool-proof installation and ensure the accuracy of positioning installation.

[0052] Optionally, the light guide portion 320 and the light splitter portion 310 are integrally formed. The light guide portion 320 is cylindrical, and the light splitter portion 310 is semi-cylindrical.

[0053] like Figure 1 and Figure 2 As shown, further, the seat body 140 is further provided with a support portion 160, which is arranged opposite to the abutment portion 130 and cooperates with the circumferential side wall of the light splitter 310. In this way, the support portion 160 and the abutment portion 130 are used to limit the circumferential side wall of the light splitter 310, so that the radial movement of the light splitter 310 can be limited to achieve radial limitation. Combined with the axial limitation of the light splitter element 300 by the abutment portion 130 and the abutment element 200, it is ensured that the light splitter element 300 is stably and reliably installed in the light passage 110. In addition, the extension height of the support portion 160 relative to the sleeve body 150 (such as Figure 2H) matches the difference between the outer diameter of the light guide part 320 and the outer diameter of the light splitting part 310, so that the circumferential limiting effect of the light splitting element 300 is better, and the installation of the light splitting element 300 can also be positioned. In addition, the support part 160 and the abutment part 130 form a bayonet structure for pre-positioning the light splitting element 300, which improves the overall structural strength of the mounting seat 100, and then the abutment element 200 is used to finally install and fix the light splitting element 300, which improves the assembly accuracy and reduces the assembly difficulty.

[0054] The support portion 160 may be in the form of a support platform, and the support portion 160 may achieve surface contact with the beam splitter element 300 , thereby achieving a better circumferential limiting effect on the beam splitter element 300 .

[0055] like Figure 2 As shown, in addition, the camera structure capable of splitting light further includes a first sensor element 400 and a second sensor element 500. The first sensor element 400 is arranged at the light exit side corresponding to the first light hole 120 to detect the optical signal of the first light, and the second sensor element 500 is arranged at the light exit side corresponding to the second light hole 210 to detect the optical signal of the second light. In this way, the first sensor element 400 and the second sensor element 500 can be used to realize multi-directional collection of optical signals, thereby achieving the infrared blood-penetrating and fog-penetrating effects.

[0056] Among them, the first sensor element 400 can be installed at the first light hole 120 by plugging or the like, and further, the first sensor element 400 can be connected to the mounting base 100 by screwing or bonding or the like to achieve a more stable and reliable connection; the second sensor element 500 can be installed at the second light hole 210 by plugging or the like, and further, the second sensor element 500 can be connected to the mounting base 100 by screwing or bonding or the like to achieve a more stable and reliable connection.

[0057] Optionally, the first sensor element 400 and the second sensor element 500 may both be CMOS (Complementary Metal-Oxide-Semiconductor) sensors, which are smaller in size, thereby making the external size of the camera structure smaller.

[0058] like Figure 1 As shown, further, the camera structure capable of splitting light further includes a shielding sleeve 600, which is sleeved on the outer side of the sleeve body 150, and the first sensor element 400 and the second sensor element 500 are both arranged in the shielding sleeve 600. In this way, the shielding sleeve 600 can shield external signals, thereby preventing external signals from interfering with or affecting the signal collection and transmission of the first sensor element 400 and the second sensor element 500, thereby ensuring the accuracy of the collection results.

[0059] The shielding sleeve 600 may be made of a material with shielding properties such as metal.

[0060] like Figure 1 As shown, further, a bending portion 610 is provided at one end of the shielding sleeve 600 facing the seat body 140, and the bending portion 610 is in contact with the seat body 140. In this way, when the shielding sleeve 600 is sleeved on the outer side of the sleeve body 150, the shielding sleeve 600 can be pushed along the axial direction of the sleeve body 150 until the bending portion 610 contacts the seat body 140 and cannot be pushed, and it can be determined that the shielding sleeve 600 is installed in place, thereby improving the assembly accuracy and reducing the assembly difficulty.

[0061] like Figure 1 and Figure 2 As shown, in one embodiment, the camera structure capable of splitting light further includes a protective member 700. The protective member 700 is disposed in the light passage 110 and is located on the light incident side of the light splitting element 300. In this way, the light splitting element 300 located in the light passage 110 is isolated from the outside by the protective member 700 to prevent the outside from interfering with the light splitting element 300. In addition, 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 light-transmitting portion and be emitted to the light splitting element 300 without causing any influence or interference.

[0062] 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.

[0068] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0069] It should be noted that when an element is referred to as being "fixed on", "set on", "fixed on" or "installed on" another element, it can be directly on the other element or there can be a central element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there can be a central element at the same time. Further, when an element is considered to be "fixed transmission connected" to another element, the two can be fixed in a detachable connection manner or in a non-detachable connection, as long as power transmission can be achieved, such as socketing, snap-on, one-piece molding fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0070] It should also be understood that when explaining the connection relationship or positional relationship of elements, although not explicitly described, the connection relationship and positional relationship are interpreted as including an error range, which should be within the acceptable deviation range of a specific value determined by those skilled in the art. For example, "approximately", "approximately" or "substantially" may mean within one or more standard deviations, which are not limited here.

[0071] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
