Description

Technical Field

[0001] This application relates to the field of medical devices, and more particularly to an endoscope host. Background Technology

[0002] Endoscopes have wide applications in medicine, and endoscope main units come in two types: integrated and separate. Integrated endoscope main units combine the motherboard and lighting device into a single device, offering high integration. However, their overall space is limited, and the internal functional components are relatively large. When some components (such as the motherboard) malfunction, many parts need to be removed for maintenance, making the product inconvenient for the customer to maintain. Therefore, how to easily disassemble the internal components of integrated endoscope main units is a problem that urgently needs to be solved. Utility Model Content

[0003] This application provides an endoscope host, including a back plate with a first sub-plate and a second sub-plate. By detachably connecting the second sub-plate to the first sub-plate and closing the opening of the back plate, some parts of the endoscope host, such as the motherboard, can be disassembled and installed along the length direction through the opening without touching other parts in the thickness direction, which facilitates the disassembly and assembly of internal parts of the endoscope host.

[0004] In a first aspect, embodiments of this application propose an endoscope host, including a housing, a back plate, a substrate, a light-emitting device, and a main board. The housing, substrate, and back plate together form a cavity. The main board and the light-emitting device are located inside the cavity. The light-emitting device covers the protrusion of the main board in the thickness direction. The back plate includes a first sub-plate and a second sub-plate. The first sub-plate is integrally formed with the housing. The second sub-plate is detachably connected to the first sub-plate and closes the opening of the back plate. The opening is used for detaching and installing the main board in the length direction.

[0005] This embodiment of the application incorporates a backplate comprising a first sub-plate and a second sub-plate within the endoscope host. The second sub-plate is detachably connected to the first sub-plate and closes the opening of the backplate. When the mainboard needs to be removed from the cavity, the second sub-plate is removed from the first sub-plate to open the opening. The mainboard can then be easily removed from the cavity simply by pulling it out through the opening. This eliminates the need to disturb other components in the thickness direction of the endoscope host, such as light-emitting devices, thus avoiding disturbance to these precision parts and facilitating the disassembly and assembly of the internal components of the endoscope host.

[0006] In one possible implementation, the endoscope main unit further includes a mounting plate disposed on the second sub-board, with the mounting plate, main board, and base plate stacked sequentially. By placing the mounting plate on the second sub-board, when the main board needs to be removed from the cavity, the mounting plate can be removed simultaneously from the first sub-board, thus avoiding interference with the disassembly and assembly of the main board and facilitating the disassembly and assembly of the internal components of the endoscope main unit.

[0007] In one possible implementation, the endoscope host also includes a wiring harness with two terminals, which are connected to the mounting plate and the main board respectively. When the second sub-board is removed from the first sub-board, the mounting plate can be pulled out without disturbing the main board by disconnecting one terminal from the main board, thereby avoiding disturbance to the main board and other components, and facilitating the subsequent disassembly and assembly of internal parts of the endoscope host.

[0008] In one possible implementation, the mounting plate has multiple protruding interfaces that pass through multiple through holes in the second sub-board. By providing multiple through holes on the second sub-board and having multiple interfaces pass through them, the data reception and transmission requirements of the mounting plate and the main board can be met, while the second sub-board isolates the various components inside the cavity from the outside, thus protecting the internal parts of the endoscope host. When the second sub-board is removed from the first sub-board, the multiple interfaces of the mounting plate can pass through the multiple through holes of the second sub-board, and the second sub-board will not have additional contact with the mounting plate, thereby avoiding disturbance to the main board and other components, and facilitating the subsequent disassembly and assembly of the internal parts of the endoscope host.

[0009] In one possible implementation, the through-hole is a first through-hole, and the second daughter board also has a plurality of second through-holes arranged sequentially with the first through-hole along the thickness direction. The interface is a first interface, and the motherboard is provided with a plurality of second interfaces, which pass through the plurality of second through-holes. By setting a plurality of second through-holes on the second daughter board and having a plurality of second interfaces pass through the plurality of second through-holes, the data reception and transmission requirements between the motherboard and the outside world can be met, while the various components inside the cavity are isolated from the outside world by the second daughter board, thereby protecting the internal components of the endoscope host. When the second daughter board is removed from the first daughter board, the plurality of second interfaces of the motherboard can pass through the plurality of second through-holes of the second daughter board respectively, and the second daughter board will not make additional contact with the motherboard, thereby avoiding disturbance to the motherboard and other components, and facilitating the subsequent disassembly and assembly of the internal components of the endoscope host.

[0010] In one possible implementation, the first sub-plate has a first threaded hole, and the second sub-plate has a second threaded hole. The second sub-plate is threadedly connected to the first sub-plate, which makes the connection between the second sub-plate and the first sub-plate stable, and the second sub-plate is easy to remove from the first sub-plate, which facilitates the subsequent disassembly and assembly of internal parts of the endoscope host.

[0011] In one possible implementation, the endoscope host also includes three fans, and the first sub-board has three air outlets, with the three fans corresponding to the three air outlets. By corresponding the three fans to the three air outlets, the fans will not interfere with the second sub-board, mounting plate, and mainboard as they move in and out of the cavity along the length of the endoscope host. This achieves efficient heat dissipation for the endoscope host while facilitating the disassembly and assembly of its internal components.

[0012] In one possible implementation, the endoscope host also includes a power supply and a filter electrically connected to the motherboard, with the power supply and filter located on the side of the motherboard away from the light-emitting device. By placing the power supply and filter on the side of the motherboard away from the light-emitting device, the paths for the motherboard, mounting plate, and second daughter board to enter and exit the cavity through the opening remain unobstructed, thereby preventing the power supply and filter from interfering with the disassembly and assembly of other components such as the motherboard, mounting plate, and second daughter board, and facilitating the disassembly and assembly of the internal parts of the endoscope host.

[0013] In one possible implementation, the endoscope host further includes a partition plate detachably connected to the substrate, at least partially covering the main body of the motherboard in the thickness direction. The partition plate can be used to separate the high-voltage and low-voltage electrical components of the motherboard, ensuring normal operation of the motherboard while simplifying the internal structure of the endoscope host and facilitating the creation of an integrated endoscope host with good ventilation and heat dissipation. By covering the main body in the thickness direction with the partition plate, the above functions can be achieved while avoiding interference with the path of the motherboard, mounting plate, and second sub-board entering and exiting the cavity along the second direction through the opening, thus facilitating the assembly and disassembly of the internal components of the endoscope host.

[0014] In one possible implementation, along the length of the endoscope host, an isolation plate, a main board, and a second daughter board are arranged sequentially. The isolation plate can be located on the side of the main board away from the second daughter board. While ensuring that the isolation plate separates the high-voltage and low-voltage electrical components of the main board, it also prevents the isolation plate from affecting the disassembly process of the main board along the length of the endoscope host from the opening, thus facilitating the disassembly and assembly of the internal components of the endoscope host.

Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0027] An endoscope is a diagnostic instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. The endoscope probe can enter the stomach through the mouth or other natural orifices, allowing visualization of lesions invisible to X-rays, greatly aiding in the development of optimal treatment plans. Endoscope main units come in two types: integrated and separate. Integrated endoscope main units combine the motherboard and lighting device into a single device, offering high integration. However, their compact size and larger internal components mean that maintenance requires disassembling numerous parts when components (such as the motherboard) malfunction, making maintenance inconvenient for customers. Therefore, facilitating the disassembly of internal components is a pressing issue that needs to be addressed.

[0028] Figure 1 This is a schematic diagram of the structure of the endoscope host 100 provided in the embodiments of this application. Figure 2 This is a schematic diagram of the internal structure of the endoscope host 100 provided in the embodiments of this application, combined with... Figure 1 and Figure 2 As shown, the endoscope host 100 includes a housing 2, a base plate 3, a back plate 4, a light-emitting device 5, and a main board 6.

[0029] Combination Figure 1 and Figure 2 As shown, the housing 2 may include a front housing 21, which extends along the width direction of the endoscope host 100. The front housing 21 may be provided with a light outlet 211, which allows light emitted by the light-emitting device 5 to pass through. The front housing 21 may also be provided with the display screen, and the light outlet 211 and the display screen are arranged sequentially along the width direction of the endoscope host 100. The display screen may be a touch screen, allowing users to directly input control commands through the display screen to achieve human-computer interaction. For example, when the user inputs a corresponding control command, the display screen may display menu switching or pop up parameter setting windows, allowing the user to further set parameters and ultimately control various working processes of the endoscope host 100 through the display screen. Schematic, the width direction of the endoscope host 100 may be the first direction shown in the attached figure, the thickness direction of the endoscope host 100 may be the third direction shown in the attached figure, and the length direction of the endoscope host 100 may be the second direction shown in the attached figure.

[0030] Combination Figure 1 and Figure 2As shown, the side of the substrate 3 facing the housing 2 can be used to support the main board 6 and the light-emitting device 5. The housing 2 can be used to cover the substrate 3, that is, the housing 2, the substrate 3, and the back plate 4 can be used to form a cavity 11, and the main board 6 and the light-emitting device 5 can both be located inside the cavity 11. The main board 6 can have a main body 61 and a protrusion 62. The protrusion 62 and the main body 61 are respectively laid in different areas of the substrate 3, and the protrusion 62 and the main body 61 can be located on the same plane. The protrusion 62 can be the part of the main board 6 that protrudes towards the light-emitting device 5. Schematic, the protrusion 62 can be regarded as an additional part extending from the main body 61 towards the light-emitting device 5, and the light-emitting device 5 covers the protrusion 62 in the thickness direction of the endoscope host 100, which is beneficial to utilize the accommodating space of the cavity 11 along the thickness direction of the endoscope host 100, so that the internal parts of the endoscope host 100 are arranged more compactly and orderly.

[0031] Combination Figure 1 and Figure 2 As shown, the backplate 4 may include a first sub-plate 41 and a second sub-plate 42. The first sub-plate 41 can be integrally formed with the housing 2, so that the backplate 4 and the housing 2 have reliable connection strength. The second sub-plate 42 is detachably connected to the first sub-plate 41 and closes the opening 43 of the backplate 4. The length of the opening 43 is greater than the dimension of the main board 6 along the width direction of the endoscope host 100, that is, the length of the opening 43 is greater than the sum of the widths of the main body 61 and the protrusion 62, so that the opening 43 can be used to remove and install the main board 6 from the length direction of the endoscope host 100. When it is necessary to remove the main board 6 from the cavity 11, the second sub-plate 42 is removed from the first sub-plate 41 to open the opening 43. At this time, the main board 6 can be removed from the cavity 11 simply by pulling it out of the opening 43. This makes the disassembly and assembly operation without touching other parts in the thickness direction of the endoscope host 100, such as the light-emitting device 5, avoiding disturbance to these precision parts and facilitating the disassembly and assembly of the internal parts of the endoscope host 100.

[0032] Combination Figure 1 and Figure 2 As shown, in one possible implementation, the endoscope host 100 further includes a mounting plate 7 disposed on the second sub-board 42. The mounting plate 7 can cover part of the main body 61 of the main board 6, that is, the mounting plate 7, the main board 6, and the substrate 3 can be stacked sequentially along the thickness direction of the endoscope host 100. The mounting plate 7 can be used to install functional components such as circuit boards and electrical interfaces to ensure that the main board 6 executes various operating commands. By disposing of the mounting plate 7 on the second sub-board 42, when the main board 6 needs to be removed from the cavity 11, the mounting plate 7 can also be removed at the same time as the second sub-board 42 is removed from the first sub-board 41, thereby avoiding any impact on the disassembly and assembly of the main board 6 and facilitating the disassembly and assembly of the internal parts of the endoscope host 100.

[0033] Figure 3 A top view of the internal structure of the endoscope host 100 provided in this embodiment of the application. Figure 4 This is an exploded view of the endoscope host 100 provided in the embodiments of this application, combined with Figure 1 , Figure 3 and Figure 4 As shown, in one possible implementation, the endoscope host 100 may further include a wiring harness 8 with two terminals 81, which can be connected to the main board 6 and the mounting plate 7 respectively via the two terminals 81. Both terminals 81 are detachably connected to the main board 6 and the mounting plate 7. The wiring harness 8 can be used to transmit electronic data between the main board 6 and the mounting plate 7, which facilitates the main board 6 to quickly execute operating commands. When the second sub-board 42 is removed from the first sub-board 41, the mounting plate 7 can be removed without disturbing the main board 6 by disconnecting one terminal 81 from the main board 6, thereby avoiding disturbance to the main board 6 and other components, and facilitating the subsequent disassembly and assembly of internal parts of the endoscope host 100.

[0034] Figure 5 This is a rear view of the endoscope host 100 provided in the embodiments of this application, combined with... Figure 1 , Figure 4 and Figure 5 As shown, in one possible implementation, the mounting plate 7 has multiple protruding interfaces 71, which pass through multiple through holes 421 of the second sub-plate 42. The interfaces 71 can be used to connect to external data ports to meet the data reception and transmission requirements of the mounting plate 7 and the motherboard 6. By providing multiple through holes 421 on the second sub-plate 42 and having multiple interfaces 71 pass through them, the data reception and transmission requirements of the mounting plate 7 and the motherboard 6 can be met, while the second sub-plate 42 isolates the various components inside the cavity 11 from the outside, thus protecting the internal parts of the endoscope host 100. When the second sub-plate 42 is removed from the first sub-plate 41, the multiple interfaces 71 of the mounting plate 7 can pass through the multiple through holes 421 of the second sub-plate 42 respectively, and the second sub-plate 42 will not have additional contact with the mounting plate 7, thereby avoiding disturbance to the motherboard 6 and other components, and facilitating the subsequent disassembly and assembly of the internal parts of the endoscope host 100.

[0035] Combination Figure 1 , Figure 4 and Figure 5As shown, in one possible implementation, the through-hole 421 in the above embodiment is a first through-hole 421. The second sub-board 42 also has a plurality of second through-holes 422 arranged sequentially along the thickness direction with the first through-hole 421. The plurality of second through-holes 422 can be arranged sequentially along the width direction of the endoscope host 100. The interface 71 in the above embodiment is a first interface 71. The motherboard 6 can also be provided with a plurality of second interfaces 63, which can be arranged sequentially along the width direction of the endoscope host 100. The plurality of second interfaces 63 can penetrate the plurality of second through-holes 422, that is, the plurality of second interfaces 63 can correspond one-to-one with the plurality of second through-holes 422. Schematic, the number of second interfaces 63 can be equal to the number of second through-holes 422. The second interfaces 63 can be used to connect to external data ports to meet the data reception and transmission requirements of the motherboard 6. By setting multiple second through holes 422 on the second daughter board 42 and passing multiple second interfaces 63 through the multiple second through holes 422, the data reception and transmission requirements of the motherboard 6 to the outside world can be met, while the various components inside the cavity 11 are isolated from the outside world by the second daughter board 42, so as to protect the internal parts of the endoscope host 100. When the second daughter board 42 is removed from the first daughter board 41, the multiple second interfaces 63 of the motherboard 6 can pass through the multiple second through holes 422 of the second daughter board 42 respectively. The second daughter board 42 will not make additional contact with the motherboard 6, thereby avoiding disturbance to the motherboard 6 and other components, and facilitating the subsequent disassembly and assembly of the internal parts of the endoscope host 100.

[0036] Combination Figure 1 , Figure 4 and Figure 5 As shown, in one possible implementation, the first sub-plate 41 may have a first threaded hole 411, and the second sub-plate 42 may have a second threaded hole 423. The second sub-plate 42 can be threadedly connected to the first sub-plate 41 through the cooperation of the second threaded hole 423 and the first threaded hole 411, so that the connection between the second sub-plate 42 and the first sub-plate 41 is stable, and the second sub-plate 42 can be easily removed from the first sub-plate 41, which facilitates the subsequent disassembly and assembly of the internal parts of the endoscope host 100.

[0037] Combination Figure 1 , Figure 2 and Figure 4As shown, in one possible implementation, the endoscope host 100 may further include three fans 9, all of which can be mounted on the first sub-board 41, i.e., all fans 9 are positioned relative to the second sub-board 42, mounting plate 7, and main board 6 along the thickness direction of the endoscope host 100. The first sub-board 41 may also have three air outlets 412, and the three fans 9 and the three air outlets 412 can be respectively positioned correspondingly. Two fans 9 can be positioned relative to the light-emitting device 5 to dissipate the heat generated by the light-emitting device 5 through the two oppositely positioned air outlets 412. The other fan 9 can be positioned relative to the main board 6 to dissipate the heat generated by the main board 6 through the other oppositely positioned air outlet 412. By correspondingly positioning the three fans 9 and the three air outlets 412, the fans 9 will not interfere with the second sub-board 42, mounting plate 7, and main board 6 as they move in and out of the cavity 11 along the length direction of the endoscope host 100. This achieves efficient heat dissipation for the endoscope host 100 while facilitating the disassembly and assembly of the internal components of the endoscope host 100.

[0038] Combination Figure 1 and Figure 3 As shown, in one possible implementation, the endoscope host 100 may further include a power supply 10 and a filter 12 electrically connected to the motherboard 6. Both the power supply 10 and the filter 12 may be located on the side of the motherboard 6 away from the light-emitting device 5. The filter 12 can be used to suppress noise and high-frequency harmonics generated by the switching power supply 10, thereby reducing the leakage current of the power supply 10 and better providing power to the motherboard 6. By placing the power supply 10 and the filter 12 on the side of the motherboard 6 away from the light-emitting device 5, the paths for the motherboard 6, mounting plate 7, and second sub-board 42 to enter and exit the cavity 11 through the opening 43 remain unobstructed. This avoids interference from the power supply 10 and the filter 12 on the disassembly and assembly of other components such as the motherboard 6, mounting plate 7, and second sub-board 42, facilitating the disassembly and assembly of internal parts of the endoscope host 100.

[0039] Combination Figure 1 and Figure 3As shown, in one possible implementation, the endoscope host 100 may further include an isolation plate 13 detachably connected to the substrate 3, at least a portion of the isolation plate 13 covering the main body 61 of the motherboard 6 in the thickness direction. The isolation plate 13 is stacked with both the motherboard 6 and the substrate 3, i.e., a portion of the isolation plate 13 is laid on the substrate 3, and another portion is laid on the main body 61. The isolation plate 13 is located between the front shell 21 and the motherboard 6, with a gap between the isolation plate 13 and the front shell 21. Multiple air inlets are disposed in this gap, i.e., multiple air inlets are located between the front shell 21 and the isolation plate 13. The isolation plate 13 can be used to separate the high-voltage and low-voltage electrical components of the motherboard 6, ensuring the normal operation of the motherboard 6 while simplifying the internal structure of the endoscope host 100, thus facilitating the realization of an integrated endoscope host 100 with good ventilation and heat dissipation pathways. By covering the main body 61 with the partition plate 13 in the thickness direction, the above-mentioned functions can be achieved while avoiding interference with the path of the main board 6, the mounting plate 7 and the second sub-board 42 entering and exiting the cavity 11 through the opening 43 in the second direction, which facilitates the disassembly and assembly of the internal parts of the endoscope host 100.

[0040] Combination Figure 1 , Figure 2 and Figure 3 As shown, in one possible implementation, along the length of the endoscope host 100, the isolation plate 13, the main board 6, and the second daughter board 42 can be arranged sequentially. The isolation plate 13 can be located on the side of the main board 6 away from the second daughter board 42. While ensuring that the isolation plate 13 separates the high-voltage power supply part and the low-voltage power supply part of the main board 6, it avoids the isolation plate 13 affecting the process of disassembling the main board 6 from the opening 43 along the second direction, thus facilitating the disassembly and assembly of the internal parts of the endoscope host 100.

[0041] Combination Figure 1 and Figure 2 As shown, the endoscope host 100 may further include a baffle 14 located between the light-emitting device 5 and the main body 61 of the motherboard 6, the baffle 14 being perpendicular to the first direction. The baffle 14 can be used to electrically isolate the light-emitting device 5 from the main body 61 of the motherboard 6 to avoid current crosstalk between the light-emitting device 5 and the main body 61. The baffle 14 can also be used to support the light-emitting device 5, so that the light-emitting device 5 can be detachably mounted on the substrate 3, which helps to reduce the internal structural complexity of the endoscope host 100 and realize an integrated endoscope host 100 with good ventilation and heat dissipation path.

[0042] Combination Figure 1 , Figure 2 and Figure 3As shown, the endoscope host 100 may also include an air pump module 15, which can be used to deliver gas and liquid. During the use of the endoscope, the endoscope probe needs to be inserted into the human body. The human body contains folds in the intestines, gastrointestinal fluid, or other objects that can easily obstruct the endoscope probe, thus affecting the imaging effect. The air pump module 15 provides liquid and gas to the endoscope probe, thereby achieving the purpose of flushing the endoscope probe and clearing the intestines, keeping the endoscope probe clean and gently pushing open the intestines, which is beneficial for imaging by the endoscope host 100. The air pump module 15 is detachably connected to the base plate 3 via a platform with four pins, meaning the air pump module 15 is suspended relative to the base plate 3. The air pump module 15 has multiple through holes at one end near the substrate 3, which allows cold air from outside the endoscope host 100 to enter through the multiple through holes and pass through the gap between the air pump module 15 and the substrate 3 to enter the heat dissipation path to remove the heat from the motherboard 6. This helps to efficiently dissipate the heat generated by the motherboard 6 and ensure the working efficiency of the endoscope host 100.
