[0002] The permanent structure of the existing medical endoscope system includes a cold light source, an image processor, a mirror body and a trolley. The cold light source mainly provides lighting for the system, the image processor mainly performs image acquisition and image processing, the mirror body is the operating functional body between the cold light source and the inspection object, and is also the front end of image acquisition. The trolley is the carrier of the cold light source, processor and display and the keyboard operating console.

[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0059] The core of the present invention is to provide an endoscope system in which a cold light source and an image processor are integrated into one body to ensure the convenience of operation and maintenance of the whole machine. The circuit board of the image processor is set to be double-layered to reduce the size of the image processor, making it small and lightweight for easy transportation.

[0060] Please refer to Figures 1 to 12 The present application provides an endoscope system, which mainly includes a housing 700, a cold light source module 100, an image processing module 200, a power supply module 300, and the like.

[0061] The housing 700 is a container having an inner cavity. The cold light source module 100 and the image processing module 200 are both disposed in the housing 700 .

[0062] The image processing module 200 includes at least two circuit boards, which are stacked with a gap in the stacking direction. The cold light source module 100 is disposed on the side of the circuit board.

[0063] The circuit board may be a main control circuit board in the endoscope system, or a control circuit board of any device in the endoscope system.

[0064] Optionally, both circuit boards are horizontally arranged relative to the bottom surface of the housing 700, including the two circuit boards being parallel to the bottom surface, or having a small inclination angle with the bottom surface, which should be less than 10 degrees. Compared with the vertical placement of the circuit boards, horizontal placement is more stable.

[0065] "Two circuit boards are stacked" means that their projections onto their bottom surfaces overlap, thus achieving vertical overlap. "A gap" between them means that they are not positioned flush against each other, leaving a gap for arranging electronic components or enabling airflow. The cold light source module 100 is positioned on the side of the circuit board. Specifically, the cold light source module 100 can be positioned at the edge of the stacked circuit board. For example, if several circuit boards are stacked longitudinally, the cold light source module 100 is positioned on one side of the circuit board in the transverse direction. Because the circuit boards are stacked longitudinally, the longitudinal space is utilized, making their longitudinal height more compatible with the cold light source module 100, thereby fully utilizing the longitudinal space. The cold light source module 100 and the circuit board are arranged horizontally side by side or spaced apart, which can improve stability and facilitate maintenance operations. Stacking the two circuit boards one above the other increases the vertical space occupied. Horizontally arranging the circuit board and the cold light source module 100 reduces the vertical space occupied by both, achieving efficient space utilization. Alternatively, the circuit boards may be arranged vertically, with several circuit boards arranged in sequence along the horizontal direction, with the cold light source module 100 positioned on one side of the circuit board in the horizontal direction. Alternatively, the cold light source module 100 may be positioned on one side of the circuit board in the longitudinal direction. The horizontal or vertical arrangement of the circuit boards, as well as the stacking height and width, may depend on the height and width of the cold light source module 100 and its positional relationship with the circuit boards. Alternatively, the positional relationship between the cold light source module 100 and the circuit boards may depend on the stacking height and width of the several circuit boards, and the two may be matched to facilitate space utilization.

[0066] In the present application, the cold light source module 100 and the image processing module 200 are respectively integrated modules. The height of the stacking space for the circuit boards can be designed and determined according to the height of the cold light source module 100, thereby fully utilizing the longitudinal space inside the housing 700 and improving the efficiency of the assembly process of the entire machine, greatly optimizing production efficiency. Moreover, since the two are integrated into a whole, it is convenient to integrate structural redundancy, achieve an overall lightweight design, and facilitate maintenance and transportation.

[0067] Alternatively, optionally, the above-mentioned circuit boards may also be arranged vertically, that is, perpendicular to the horizontal direction, and the two circuit boards are stacked in sequence along the horizontal direction with a gap therebetween.

[0068] The above two circuit boards have various application types and may include an image acquisition circuit board 21 for processing images and a main control circuit board 22. The image acquisition circuit board 21 is connected to a mirror body for acquiring images, and image acquisition can be achieved when the mirror body is operated. The image acquisition circuit board 21 is connected to the mirror body to acquire images from the mirror body and process the acquired images.

[0069] The main control circuit board 22 is the controller of the endoscope system, which connects various functional modules, human-computer interaction mechanisms or interfaces, obtains data from each module and obtains human-computer interaction instructions, thereby realizing control and data output according to the instructions and data.

[0070] The image acquisition circuit board 21 can be connected to a mirror device for image acquisition to directly obtain images and can be used to process images.

[0071] In this embodiment, the image acquisition circuit board 21 and the main control circuit board 22 are placed in two layers, the circuit board arrangement is required, and it conforms to the common height setting of the cold light source module 100. On the other hand, considering that the image processing module 200 is an integrated setting, the two circuit boards are arranged separately to achieve functional independence and integrity, which can realize fast and accurate partition maintenance.

[0072] Preferably, the image acquisition circuit board 21 is located below the main control circuit board 22 , and the area of ​​the image acquisition circuit board 21 is larger than that of the main control circuit board 22 .

[0073] It should be noted that the above-mentioned area refers to the board area on the circuit board that can be used to set circuit elements and modules. The area of ​​the image acquisition circuit board 21 is larger than the area of ​​the main control circuit board 22, which means that the image acquisition circuit board 21 has a larger area for setting circuit elements and modules than the main control circuit board 22, and the image acquisition circuit board 21 can be set with more elements and modules.

[0074] When the two are arranged in an upper and lower layer, considering that the image acquisition circuit board 21 has many functional components and requires a larger PCB area, placing it in the lower layer facilitates structural stability and allows for easier viewing of more components and connectors from the top or side, facilitating installation and maintenance. At the same time, since other modules are located at the bottom of the housing 700, the larger circuit board is located at the bottom, facilitating connection with other modules. Optionally, the two circuit boards can be provided with connectors and fixtures separately, or they can be fixedly connected and provided with unified connectors and fixtures.

[0075] Based on any of the above embodiments, the image acquisition circuit board 21 and the main control circuit board 22 are connected in circuit, the main control circuit board 22 is connected to the power module 300, and the image acquisition circuit board 21 is provided with a connector for external output of the circuit.

[0076] The main control circuit board 22 obtains electrical energy through the power module 300 and transmits power to the image acquisition circuit board 21 through circuit connection with the image acquisition circuit board 21. The connector set on the image acquisition circuit board 21 can be used to realize signal output between the image acquisition circuit board 21 and the main control circuit board 22.

[0077] In this embodiment, the connector is located on the lower layer of the image acquisition circuit board 21, assigning the external output functions of both circuit boards to the image acquisition circuit board 21. This lower-layer arrangement provides a more stable connector position, avoids top-heavy behavior, and ensures the stability of the circuit boards. Alternatively, if the connector is located on the upper layer of the main control circuit board 22, it needs to be fixed to the side wall of the housing 700 to avoid adding weight to the main control circuit board 22.

[0078] In the above embodiment, the main control circuit board 22 and the image acquisition circuit board 21 are stacked with a gap, including a partial overlapping area between the two or at least one of them is completely located in the overlapping area. Such a staggered arrangement can effectively avoid the position of the connector on the lower circuit board, avoiding the inconvenience of plugging and unplugging.

[0079] Specifically, a first side edge of the main control circuit board 22 is aligned with a first side edge of the image acquisition circuit board 21 in the vertical direction, and the remaining three side edges of the image acquisition circuit board 21 all protrude from corresponding side edges of the corresponding main control circuit board 22 .

[0080] In other words, the projection of the main control circuit board 22 onto the bottom surface is completely located within the image acquisition circuit board 21 and is located at one edge of the image acquisition circuit board 21. The two first side edges can be aligned and connected to the side edges of the housing 700 to align the two circuit boards. The remaining three side edges of the image acquisition circuit board 21 are located outside the projection of the main control circuit board 22 and can be used to arrange circuit board components.

[0081] Optionally, one side of the image acquisition circuit board 21 protrudes from the main control circuit board 22 by at least 20 mm, which can facilitate the plugging and unplugging of the external connector.

[0082] Optionally, the endoscope system also includes a core circuit board 23 for storing the UI interface and images. The image acquisition circuit board 21 is circuit-connected to the core circuit board 23. The core circuit board 23 is arranged parallel to the image acquisition circuit board 21 and is located on one of the other three sides of the image acquisition circuit board 21.

[0083] Optionally, the image acquisition circuit board 21 and the core circuit board 23 provided in the present application can be fixed to the adapter 26 by bolts, and the adapter 26 is fixed on the studs of the bottom plate of the shell 700. It should be noted that there is a preset distance between the adapter 26 and the bottom plate of the shell 700 to provide airflow heat dissipation for the circuit board.

[0084] In any of the above embodiments, the main control circuit board 22 is located above the core components on the image acquisition circuit board 21, and the image acquisition circuit board 21 is provided with a shielding cover 25 surrounding the core components for shielding signals, and the shielding cover 25 is located between the main control circuit board 22 and the image acquisition circuit board 21.

[0085] The shielding cover 25 surrounds and encloses the overlapping area between the main control circuit board 22 and the image acquisition circuit board 21. The shielding cover 25 can be fixedly connected to or in contact with each of the main control circuit board 22 and the image acquisition circuit board 21. Core components are located within this overlapping area, on the image acquisition circuit board 21. In this embodiment, the shielding cover 25 shields this area from external interference, effectively providing shielding protection for the core components of the underlying image acquisition circuit board 21 within a defined space.

[0086] Optionally, when the number of main control circuit boards 22 is not unique, a corresponding number of shielding covers 25 may be provided, each corresponding to the core components at different positions on the image acquisition circuit board 21 .

[0087] The distance between the upper and lower circuit boards can be at least 21.5 mm, preferably 60 mm, to facilitate the setting of the shielding cover 25. A power supply module 300 is provided on the side of the image processing module 200 (other modules can also be provided). The distance between the power supply module 300 and the lower image processing module 200 (optionally 10 mm) is smaller than the distance with the upper main control circuit board 22 (optionally 31.5 mm).

[0088] In the above embodiment, core components typically have high heat dissipation requirements. Therefore, heat dissipation holes are provided in the shielding cover 25, and board cooling fans 27 are provided at the heat dissipation holes to dissipate heat from the core components. The shielding cover 25 can have two heat dissipation holes, one of which is provided with a fan for air drainage, and the other heat dissipation hole is connected to the outside to achieve air outflow; or the shielding cover 25 can have multiple heat dissipation holes on its surface, and the board cooling fan 27 is provided on the shielding cover 25, and is not limited to the direction of airflow; specifically, the shielding cover 25 has heat dissipation holes on three sides, with the heat dissipation holes on one side for air intake and the heat dissipation holes on the other two sides for air exhaust.

[0089] Alternatively, the main control circuit board 22 and the image acquisition circuit board 21 are positioned and connected via spacer posts 24, or both are connected within the housing 700. It should be noted that the space formed by the spacer posts 24 and the two circuit boards is the space enclosed by the shielding cover 25, and the spacer posts 24 stabilize the position of the two circuit boards. Optionally, the main control circuit board 22 is secured to the spacer posts 24 via bolts and secured to the side panels of the housing 700 via connectors.

[0090] For the cold light source module 100 provided by the above-mentioned endoscope system, the present application provides a specific implementation method, in which the cold light source module 100 includes at least an LED-white light device 12, an LED-UV light device 11, a filter assembly 13, a converging lens assembly 14, a light guide portion 15, and an optical path base plate 17.

[0091] The optical path bottom plate 17 can be set on the bottom plate of the housing 700, and a filter assembly 13 is provided in the middle of the optical path bottom plate 17 for realizing reflection and transmission of light.

[0092] The optical path base plate 17 is a rectangular structure. The LED-white light device 12 and the LED-UV light device 11 are light generating devices for generating white light and UV light, and the two are respectively arranged on the side of the optical path base plate 17. The converging lens assembly 14 is also arranged on the side of the optical path base plate 17.

[0093] It should be noted that the LED-white light device 12 , the LED-UV light device 11 and the converging lens assembly 14 can be arranged at different side positions of the optical path base plate 17 .

[0094] Since the optical path base plate 17 is a rectangular plate, it has four edges, i.e., four sides. The LED-white light device 12 and the LED-UV light device 11 can be respectively arranged on two adjacent sides. Preferably, the converging lens assembly 14 can be arranged on another side of the optical path base plate 17, i.e., different from the two sides where the LED-white light device 12 and the LED-UV light device 11 are arranged. In this way, the converging lens assembly 14, the LED-white light device 12, and the LED-UV light device 11 are distributed at different positions on the optical path base plate 17 to avoid interference.

[0095] Optionally, the converging lens assembly 14 , the filter assembly 13 , and the LED-white light device 12 are arranged along a straight line.

[0096] The converging lens assembly 14 converges the light beams before coupling, converging them at a location within the light guide 15. The lens body is inserted into the light guide 15, coupling the light beams into the optical fibers within the lens body. The LED-white light device 12 and the LED-UV light device 11 are each connected to a filter assembly 13, which reflects and transmits the light beams emitted by the filter assembly 13 before directing them toward the converging lens assembly 14.

[0097] Specifically, the LED-UV light device 11 is fixed on the optical path base plate 17 through a support frame, and the LED-white light device 12 is fixed on a side surface of the optical path base plate 17 through a support frame.

[0098] The converging lens assembly 14 is arranged on the support frame of the optical path base plate 17. The converging lens assembly 14 includes a lens seat arranged on the support frame. The lens seat is provided with a lens. The lens seat can adjust the relative position relationship through the relative movement of its own external thread and the internal thread of the support frame, thereby adjusting the converging state of the light beam.

[0099] The light beam converged by the converging lens assembly 14 converges on the light guiding portion 15 . The light guiding portion 15 is used to connect to the mirror body and guide the converged light beam into the mirror body.

[0100] Optionally, a light guide heat dissipation component 16 is further included to dissipate heat for the light guide 15 . The light guide heat dissipation component 16 may be a fan and / or heat dissipation fins.

[0101] Optionally, a light path cover 18 is provided outside the filter assembly 13 .

[0102] Optionally, the LED-white light device 12, the LED-UV light device 11, and the light guide 15 are all provided with a heat dissipation device. The heat dissipation device includes a light source fan 19 provided on each component and / or heat dissipation fins provided on each component.

[0103] Based on any of the above embodiments, the housing 700 includes an upper shell 71 and a lower shell 72 .

[0104] A front panel 75 and a tail panel 74 are fixedly provided on the front and rear sides of the lower shell 72 respectively. The front panel 75 is provided with a positioning clamping portion.

[0105] The upper shell 71 is an inverted U-shaped shell, which is slidably arranged on the lower shell 72. The upper shell 71 is provided with a pressing tongue 73 that cooperates with the positioning clamping part. The U-shaped shell includes a connecting plate part located in the middle and side panels located on both sides of the connecting plate part. The three can be formed as one piece. When the upper shell 71 slides to the position where the pressing tongue 73 is clamped with the positioning clamping part, the side panels of the upper shell 71 cover the side of the area between the front panel 75 and the tail panel 74.

[0106] The lower shell 72, front panel 75, and tail panel 74 form a U-shaped plate structure. This U-shaped plate structure is snap-fitted with the upper shell 71 to form a closed box. The U-shaped plate structure and the upper shell 71 can slide relative to each other to open and close the housing 700. The U-shaped plate structure forms an open groove, which facilitates the installation and maintenance of modules when the upper shell 71 is open.

[0107] The sliding structure facilitates system repair and maintenance, but to address stability issues during the sliding process, a support portion is provided between the front panel 75 and the rear panel 74. The upper shell 71 is supported on the support portion during its sliding to any position. It should be noted that the sliding of the upper shell 71 to any position includes both the movement and the stationary state at any position.

[0108] The support portion can keep the upper shell 71 at a constant height, avoid interference or scratches with components and cables in the housing 700 during sliding, and prevent the upper shell 71 from falling into the lower shell 72 during sliding.

[0109] Specifically, the support portion includes a tie rod 76, which has a step on one side near the rear panel 74. When the upper housing 71 slides to a position where the tongue 73 engages the step, the area between the front panel 75 and the rear panel 74 is exposed. The area between the front panel 75 and the rear panel 74 is used to house the cold light source module 100 and the image processing module 200. Exposing this area indicates that the housing 700 is in an open state.

[0110] It should be noted that the tie rod 76 is a rigid structure used to support the upper shell 71. The tie rod 76 is fixed to the front panel 75 and the tail plate 74 by bolts or other means, providing support and sliding guidance for the upper shell 71. A step is provided on the side near the tail plate 74 so that when the upper shell 71 slides toward the tail plate 74, the upper shell 71's pressing tongue engages with the step to prevent it from sliding.

[0111] Optionally, the support portion (tensioning rod 76 ) may be provided in the middle of the lower shell 72 or on both sides of the lower shell 72 .

[0112] It should be noted that the upper shell 71 is only used for sliding to open or close the shell 700. In the above embodiment, the bottom plate of the shell 700 is the lower shell 72. Fixing structures such as circuit boards on the side plates of the shell 700 refers to fixing them on the tail plate 74 of the lower shell 72.

[0114] The power module 300 includes a box structure, and heat dissipation holes are provided on the surface of the box.

[0115] In this embodiment, a driving plate heat dissipation module 600 is further included for dissipating heat for the driving plate. The driving plate heat dissipation module 600 includes a guide cover 61 , a heat dissipation fan 62 and a support member 63 .

Each part may generate heat, and a number of corresponding heat dissipation fans are also provided in the shell 700 to form airflow.

[0121] Specifically, considering that the heat of the power module 300 may be the highest, a fan is set in the power module 300 to extract its internal heat from the inside of the power module 300 to the outside; the light source fan 19 is used to guide the heat in the corresponding light device (including the LED-UV light device 11, the LED white light device 12 and other light-emitting devices); the cooling fan 62 of the drive board heat dissipation module 600 is used to guide the airflow in the shell 700 to the inside of the guide cover 61, and discharged to the outside of the shell 700 through the tail plate heat dissipation hole 771 of the tail plate 74.

[0122] In the present application, each heat dissipation fan can be fixed to the installation position by screws, and a rubber flat washer is provided between the fan and the installation position to reduce noise.

[0126] The air pump control key is connected to the air pump module 400, and the air pump module 400 is arranged in the housing.

[0127] When the power button is triggered, the power module 300 starts up and prepares to supply power to each module. The control buttons on the front panel 75 are used to control each module.

[0128] When the light source control key is triggered, the cold light source module 100 is started, and the light beam type and the like can be adjusted through the function adjustment key.

[0129] When the air pump control key is triggered, the air pump module 400 starts. The air pump module 400 is provided with a tympanic membrane machine for outputting airflow. The airflow can adjust the pressure of different levels and can be used to cooperate with the mirror for auxiliary inspection.

[0130] Optionally, the structure on the front panel module 500 needs to cooperate with the functional settings inside the endoscope system, and each module that needs to be independently controlled can achieve human-computer interaction by setting corresponding operation keys, buttons, voice interaction devices, touch screens, etc. on the front panel module 500.

[0131] The endoscope system provided in the present application integrates the cold light source module 100 and the image processing module 200 into one, and realizes structural superposition by arranging the circuit board of the image processing module 200, thereby saving space and solving the problem of excessive weight and difficulty in carrying.
