Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a dual-lens capsule endoscope and its support and housing axial positioning structure. Background Technology

[0002] In the field of capsule endoscopy technology, dual-lens capsule endoscopes, as an advanced medical examination device, are widely used because they can provide more comprehensive images of the digestive tract. Their design typically includes a capsule shell containing an optical imaging system, electronic components, and a power supply. To achieve dual-lens imaging, both ends of the capsule shell are open to allow for the separate installation of the front and rear optical covers.

[0003] During the assembly of a dual-lens capsule endoscope, because both ends of the capsule shell are open structures, after assembling the optical front cover at one end, the capsule needs to be flipped over to assemble the optical rear cover at the other end. However, this flipping operation can easily cause the core component (capsule core) inside the capsule to fall out of the shell. This phenomenon not only increases the difficulty of assembly but may also lead to component damage during the assembly process, thereby affecting production efficiency and product quality. Utility Model Content

[0004] The purpose of this application is to provide an axial positioning structure for the support and shell of a dual-lens capsule endoscope. Axial positioning is achieved through the cooperation between the capsule core support and the capsule shell, effectively solving the problem of internal components easily detaching during the assembly of the dual-lens capsule endoscope due to the open structure of the shell, thus improving assembly stability and production efficiency. Another purpose of this application is to provide a dual-lens capsule endoscope.

[0005] To achieve the above objectives, this application provides an axial positioning structure for the support and housing of a dual-lens capsule endoscope, comprising:

[0006] The capsule shell has an internal cavity, and both ends of the capsule shell have openings that communicate with the internal cavity.

[0007] A capsule core support is located in the inner cavity of the capsule. The capsule core support is used to install an endoscope system. The capsule core support cooperates with the capsule shell to achieve axial positioning of the capsule core support relative to the capsule shell.

[0008] In some embodiments, at least one of the capsule core support and the capsule shell is provided with a first mating structure, through which the capsule core support and the capsule shell are mated.

[0009] In some embodiments, the first mating structure includes a mating block disposed on the capsule core support, the mating block being located on the side of the capsule core support facing the capsule shell, and the mating block being interference-fitted or transition-fitted with the capsule shell.

[0010] In some embodiments, the first mating structure further includes an elastic arm connected to the mating block and fixed to the capsule core support.

[0011] In some embodiments, the capsule core support, the elastic arm, and the mating block are integrally molded.

[0012] In some embodiments, there are multiple elastic arms and mating blocks, and multiple sets of elastic arms and mating blocks are symmetrically arranged on the periphery of the capsule core support.

[0013] In some embodiments, the capsule core scaffold includes:

[0014] The first annular beam is provided with a first circuit board mounting position and a second circuit board mounting position;

[0015] The second annular beam is equipped with a third circuit board slot and a first mating structure;

[0016] A support beam connects the first annular beam and the second annular beam.

[0017] In some embodiments, both the first annular beam and the second annular beam are provided with cable tray notches, which are used to avoid flexible cables connected to the circuit board.

[0018] In some embodiments, the capsule shell is provided with a limiting structure located on the side of the capsule shell facing the capsule core support. The limiting structure cooperates with a pair of adjacent support beams to achieve circumferential positioning of the capsule core support relative to the capsule shell.

[0019] This application also provides a dual-lens capsule endoscope, including the aforementioned bracket and housing axial positioning structure.

[0020] Compared with the above-mentioned background technology, the axial positioning structure of the support and shell of the dual-lens capsule endoscope provided in this application mainly includes a capsule shell and a capsule core support. The capsule shell has a capsule cavity inside, and both ends of the capsule shell are provided with openings communicating with the capsule cavity. The capsule core support is located in the capsule cavity and is used to install the endoscope system. The capsule core support cooperates with the capsule shell to achieve axial positioning of the capsule core support relative to the capsule shell.

[0021] In the design of the dual-lens capsule endoscope, both ends of its outer shell are open structures. This open structure presents a problem during assembly: after assembling the optical components at one end, when the capsule needs to be flipped to assemble the components at the other end, the capsule core inside is prone to detaching from the outer shell. This phenomenon not only increases the difficulty of assembly but may also lead to component damage, thereby affecting production efficiency and product quality.

[0022] To address this issue, this application provides an axial positioning structure for the support and shell of a dual-lens capsule endoscope. The core of this structure lies in achieving axial positioning through the cooperation between the capsule core support and the capsule shell. Specifically, the capsule shell has an internal cavity with openings at both ends communicating with the internal cavity for mounting optical components. The capsule core support is located within the internal cavity and is used to mount the endoscope system, achieving axial positioning through its cooperation with the capsule shell.

[0023] During assembly, the axial positioning function of the capsule core support plays a crucial role. Because both ends of the capsule shell are open, in traditional designs the capsule core easily slips out during flipping. However, the axial positioning structure of this application ensures the capsule core remains in the correct position throughout assembly through a tight fit between the support and the inner wall of the shell. Even when the capsule is flipped, the capsule core will not detach from the shell, effectively solving the problem of internal components easily falling off due to the open shell structure. Furthermore, the introduction of this axial positioning structure makes the assembly process more stable and reliable, reducing the need for reassembly due to component detachment, and significantly improving assembly stability and production efficiency.

[0024] Based on the above structural and process descriptions, it can be seen that the axial positioning structure of the support and shell of the dual-lens capsule endoscope has at least the following beneficial effects: The axial positioning structure of the support and shell of the dual-lens capsule endoscope achieves axial positioning through the cooperation between the capsule core support and the capsule shell, effectively solving the problem that internal components are easy to fall off during the assembly of the dual-lens capsule endoscope due to the open structure of the shell, thus improving the stability of assembly and production efficiency.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Please refer to Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the axial positioning structure of the bracket and housing of the dual-lens capsule endoscope provided in an embodiment of this application. Figure 2 This is a perspective view of the axial positioning structure of the bracket and housing of the dual-lens capsule endoscope provided in an embodiment of this application.

[0039] In a first specific embodiment, the axial positioning structure of the support and shell of the dual-lens capsule endoscope provided in this application mainly includes the capsule shell 1 and the capsule core support 2.

[0040] The capsule shell 1 is a hollow structure with open ends. The capsule shell 1 has an inner cavity 101 inside, and both ends of the capsule shell 1 are provided with openings 102 that communicate with the inner cavity 101.

[0041] The capsule core support 2 is located in the capsule cavity 101. The capsule core support 2 is used to install the endoscope system, such as circuit board, battery, etc. The capsule core support 2 cooperates with the capsule shell 1 to achieve axial positioning of the capsule core support 2 relative to the capsule shell 1.

[0042] In the design of the dual-lens capsule endoscope, both ends of its outer shell 1 are open structures. This open structure presents a problem during assembly: after assembling one end's optical components, such as the lampshade or front cover, and then flipping the capsule to assemble the other end's components, such as the lampshade or rear cover, the capsule core inside is prone to detaching from the outer shell 1. This phenomenon not only increases the difficulty of assembly but may also lead to component damage, thereby affecting production efficiency and product quality.

[0043] To address this issue, this application provides an axial positioning structure for the support and outer shell of a dual-lens capsule endoscope. The core of this structure lies in achieving axial positioning through the cooperation between the capsule core support 2 and the capsule outer shell 1. Specifically, the capsule outer shell 1 has an internal capsule cavity 101, with openings 102 at both ends communicating with the internal capsule cavity 101 for mounting optical components. The capsule core support 2 is located within the internal capsule cavity 101, used to mount the endoscope system, and achieves axial positioning through its cooperation with the capsule outer shell 1.

[0044] During assembly, the axial positioning function of the capsule core support 2 plays a crucial role. Because both ends of the capsule shell 1 are open structures, in traditional designs, the capsule core easily slips out of the opening 102 during flipping. However, the axial positioning structure of this application, through the tight fit between the support 2 and the inner wall of the shell 1, ensures that the capsule core remains in the correct position throughout the assembly process. Even when the capsule is flipped, the capsule core will not detach from the shell 1, effectively solving the problem of internal components easily detaching due to the open structure of the shell 1. Furthermore, the introduction of this axial positioning structure makes the assembly process more stable and reliable, reducing the need for reassembly due to component detachment, and significantly improving assembly stability and production efficiency.

[0045] Based on the above structural and process descriptions, it can be seen that the axial positioning structure of the bracket and shell of the dual-lens capsule endoscope has at least the following beneficial effects: The axial positioning structure of the bracket and shell of the dual-lens capsule endoscope achieves axial positioning through the cooperation of the capsule core bracket 2 and the capsule shell 1, which effectively solves the problem that internal components are easy to fall off during the assembly of the dual-lens capsule endoscope due to the open structure of the shell 1, and improves the stability of assembly and production efficiency.

[0046] In some embodiments, at least one of the capsule core support 2 and the capsule shell 1 is provided with a first mating structure 3, through which the capsule core support 2 and the capsule shell 1 are mated.

[0047] In this embodiment, the engagement between the capsule core support 2 and the capsule shell 1 is achieved through a first engagement structure 3. The core of this design is to ensure that the capsule core support 2 can achieve stable axial positioning within the capsule shell 1. The specific location of the first engagement structure 3 is flexible; it can be located on the capsule core support 2, on the capsule shell 1, or even on both. This embodiment does not limit this. This design flexibility provides more options for practical applications, allowing the optimal location to be selected based on specific structural requirements and assembly processes.

[0048] The first mating structure 3 also has diverse structural forms. For example, when mating and positioning are achieved using friction, the first mating structure 3 can be designed as a structure with protrusions or textures. Protrusions can be small protrusions evenly distributed on the surface of the capsule core support 2, generating sufficient friction to achieve axial positioning. Textures can be various regular or irregular surface treatments, such as stripes or grids, which increase the roughness of the contact surface to enhance friction and thus achieve stable mating.

[0049] Besides frictional contact, the first mating structure 3 can also employ magnetic contact. For example, magnetic materials or magnets can be placed on the capsule core support 2 or the capsule shell 1, achieving a tight fit and axial positioning between the two through magnetic attraction. The advantage of this method is that it allows for rapid assembly, and the strength of the magnetic fit can be adjusted by selecting different magnetic materials and magnet sizes to meet various application requirements.

[0050] A snap-fit ​​connection is also a possible form of the first mating structure 3. A snap-fit ​​connection typically includes one or more hooks and corresponding slots. The hooks can be located on the capsule core support 2, while the slots are located on the inner wall of the capsule shell 1, or vice versa. Through the engagement of the hooks and slots, a secure connection and axial positioning between the capsule core support 2 and the capsule shell 1 are achieved. The advantages of a snap-fit ​​connection are its simple structure, ease of assembly, and ability to achieve high positioning accuracy.

[0051] Please refer to Figure 3 , Figure 3 An exploded view of the bracket and housing axial positioning structure of the dual-lens capsule endoscope provided in the embodiments of this application.

[0052] In some cases, the first mating structure 3 is disposed on the capsule core support 2, which is easier to process and less costly than the method of disposing it on the capsule shell 1.

[0053] Please refer to Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the capsule core scaffold provided in an embodiment of this application. Figure 5 This is a schematic diagram of the capsule core scaffold provided in an embodiment of this application from another perspective.

[0054] In some embodiments, the first mating structure 3 includes a mating block 31 disposed on the capsule core support 2. The mating block 31 is located on the side of the capsule core support 2 facing the capsule shell 1, and the mating block 31 is interference-fitted or transition-fitted with the capsule shell 1.

[0055] In this embodiment, the first mating structure 3 achieves an interference fit or transition fit with the inner wall of the capsule shell 1, thereby ensuring that the capsule core support 2 is stably axially positioned within the capsule shell 1.

[0056] This design, through the tight fit between the mating block 31 and the capsule shell 1, effectively prevents the capsule core support 2 from shifting or falling off during assembly and use. The choice between an interference fit or a transition fit can be determined based on actual assembly requirements and precision specifications. An interference fit provides a tighter connection and is suitable for applications requiring higher stability and reliability; while a transition fit, while ensuring a certain level of fitting precision, allows for a degree of assembly flexibility, facilitating assembly and disassembly.

[0057] By incorporating a mating block 31 on the capsule core support 2, this design not only simplifies the structure but also reduces the complexity of processing and assembly. The design of the mating block 31 makes the fit between the capsule core support 2 and the capsule shell 1 more precise and reliable, further improving the overall performance and assembly efficiency of the dual-lens capsule endoscope.

[0058] In some embodiments, the first mating structure 3 further includes an elastic arm 32, which is connected to the mating block 31 and is fixed to the capsule core support 2.

[0059] In this embodiment, the first mating structure 3 includes not only the mating block 31, but also an elastic arm 32 connected thereto. The mating block 31 is located on the side of the capsule core support 2 facing the capsule shell 1, while the elastic arm 32 is fixed to the capsule core support 2, providing the necessary support and elastic force for the mating block 31.

[0060] The size of the mating block 31, i.e., its contact area with the capsule shell 1, directly affects the magnitude of the frictional force between them. A larger contact area provides greater friction, thereby enhancing the axial positioning stability between the capsule core support 2 and the capsule shell 1. The length of the elastic arm 32 determines the pressure it applies to the mating block 31. The longer the elastic arm 32, the stronger its elastic deformation capability, and the greater the pressure it can apply to the mating block 31, thus increasing the frictional force between the mating block 31 and the capsule shell 1.

[0061] By rationally designing the size of the mating block 31 and the length of the elastic arm 32, the axial positioning friction force when the capsule shell 1 and the capsule core support 2 mate can be precisely controlled. This design not only ensures that the capsule core support 2 is stably fixed inside the capsule shell 1 during assembly, preventing displacement or detachment during flipping or vibration, but also allows for flexible operation by appropriately reducing pressure or changing the contact area when disassembly or adjustment is needed. This flexible friction force control mechanism makes the assembly and maintenance of the dual-lens capsule endoscope more efficient and reliable, while also improving the overall performance and service life of the product.

[0062] In some embodiments, the capsule core support 2, the elastic arm 32, and the mating block 31 are designed as a single piece.

[0063] In this embodiment, this design approach has significant advantages, mainly in the following aspects:

[0064] The one-piece molding design allows the capsule core support 2, elastic arm 32, and mating block 31 to be processed and molded as a single unit during manufacturing. This not only reduces the number of parts and the complexity of assembly, but also improves the overall integrity and stability of the structure. Since there are no additional connection points, the one-piece molding design effectively avoids structural instability caused by loosening or failure of connections.

[0065] In terms of functionality, the one-piece design ensures a tight fit between the elastic arm 32 and the mating block 31 and the capsule core support 2. The elastic arm 32 provides stable elastic support for the mating block 31, ensuring that it can generate sufficient pressure when mating with the capsule shell 1, thereby achieving reliable axial positioning. At the same time, this design also makes the contact between the mating block 31 and the capsule shell 1 more uniform, further enhancing the stability of friction.

[0066] From a processing and manufacturing perspective, the unibody design simplifies the production process and reduces production costs. Through processes such as injection molding, the capsule core support 2, elastic arm 32, and mating block 31 can be manufactured in a single molding process, reducing subsequent assembly steps and labor costs. Furthermore, the unibody design also improves product manufacturing efficiency and shortens the production cycle, thus demonstrating greater advantages in large-scale production.

[0067] In summary, the capsule core support 2, the elastic arm 32, and the mating block 31 adopt an integrated molding design, which not only improves the stability of the structure and the reliability of the function, but also simplifies the production process, reduces production costs, and enhances the overall performance and market competitiveness of the product.

[0068] In some embodiments, there are multiple elastic arms 32 and mating blocks 31, and multiple sets of elastic arms 32 and mating blocks 31 are symmetrically arranged on the periphery of the capsule core support 2.

[0069] In this embodiment, this design is equivalent to having multiple first mating structures 3, thereby enhancing the axial positioning capability between the capsule core support 2 and the capsule shell 1.

[0070] Specifically, the multiple symmetrically arranged elastic arms 32 and mating blocks 31 provide more stable support and positioning. Due to the symmetrical distribution, the force borne by each set of elastic arms 32 and mating blocks 31 is more even, avoiding structural deformation or displacement caused by uneven force distribution. This symmetrical layout not only improves the stability of the structure but also enhances the reliability and durability of the entire dual-lens capsule endoscope during use.

[0071] The symmetrically arranged elastic arms 32 and mating blocks 31 ensure that the capsule core support 2 remains centered within the capsule shell 1, reducing wobbling or wear caused by eccentric torque. This design significantly improves product lifespan and reduces the risk of failure due to structural instability in practical applications.

[0072] Furthermore, the design of multiple sets of flexible arms 32 and mating blocks 31 provides greater redundancy. Even if one set experiences minor wear or damage, another set can still provide sufficient support and positioning functions, ensuring the normal operation of the equipment. This redundancy design further enhances the product's safety and reliability, making it more suitable for applications such as medical devices that require extremely high precision and stability.

[0073] In some cases, such as Figure 4 As shown, there are two elastic arms 32 and two mating blocks 31, and the two sets of elastic arms 32 and mating blocks 31 are symmetrically arranged on the periphery of the capsule core support 2.

[0074] In some embodiments, the capsule core scaffold 2 includes:

[0075] The first annular beam 21 is provided with a first circuit board slot 211 and a second circuit board slot 212;

[0076] The second annular beam 22 is provided with a third circuit board slot 221 and a first mating structure 3;

[0077] Support beam 23 connects the first annular beam 21 and the second annular beam 22.

[0078] In this embodiment, the capsule core support 2 is designed to include a first annular beam 21, a second annular beam 22, and a support beam 23. The first annular beam 21 is provided with a first circuit board slot 211 and a second circuit board slot 212 for mounting the first and second circuit boards; the second annular beam 22 is provided with a third circuit board slot 221 and a first mating structure 3 for mounting the third circuit board; the support beam 23 connects the first annular beam 21 and the second annular beam 22 to ensure the structural stability of the entire support.

[0079] The capsule shell 1 is capsule-shaped, and its internal capsule cavity 101 has a specific cross-sectional shape. To match the shape of the capsule cavity 101, both the first annular beam 21 and the second annular beam 22 are designed as annular structures, with shapes that fit the cross-sectional shape of the capsule cavity 101. This design not only improves space utilization but also ensures the stable installation of the capsule core support 2 within the capsule shell 1, reducing wobbling or displacement caused by shape mismatch.

[0080] The circuit board holders are a key structure for mounting the circuit boards. On the first annular beam 21, the first circuit board holder 211 and the second circuit board holder 212 are used to fix the first and second circuit boards, respectively, ensuring their stable installation on the capsule core support 2. The third circuit board holder 221 on the second annular beam 22 is used to mount the third circuit board. Through this design, the capsule core support 2 can effectively support and fix multiple circuit boards, meeting the complex circuit requirements of the dual-lens capsule endoscope.

[0081] Furthermore, the first mating structure 3 is mounted on the second annular beam 22 to achieve axial positioning between the capsule core support 2 and the capsule shell 1. This design not only optimizes the spatial layout but also improves the convenience and reliability of assembly. By integrating the circuit board holder and the first mating structure 3 onto the capsule core support 2, the entire dual-lens capsule endoscope has a more compact structure and a more efficient assembly process.

[0082] In some embodiments, both the first annular beam 21 and the second annular beam 22 are provided with cable routing notches. The cable routing notch of the first annular beam 21 is the first cable routing notch 213, and the cable routing notch of the second annular beam 22 is the second cable routing notch 222. The cable routing notches are used to avoid flexible cables connected to the circuit board.

[0083] In this embodiment, the design of these ribbon cable notches is intended to avoid the flexible ribbon cable connected to the circuit board, ensuring that the flexible ribbon cable will not be damaged by large-angle bending during the connection process, thereby ensuring the reliability of the connection between the flexible ribbon cable and the circuit board.

[0084] Flexible ribbon cables are essential components for connecting circuit boards, typically used to achieve electrical connections between boards within a limited space. Due to their flexibility, they require appropriate pathways during connection to avoid excessive bending or twisting. Notches in the ribbon cable design provide the necessary passageways, allowing the cable to pass smoothly through them, thus reducing the risk of signal transmission interruption or damage caused by excessive bending angles.

[0085] The first cable notch 213 on the first annular beam 21 and the second cable notch 222 on the second annular beam 22 not only provide physical clearance for the flexible cable but also optimize the layout of the entire capsule core support 2. This design allows the flexible cable to be smoothly connected to various circuit boards without interfering with other components. In this way, the cable notch design not only improves the service life of the flexible cable but also enhances the reliability and stability of the entire dual-lens capsule endoscope.

[0086] Furthermore, the design of the ribbon cable notches also takes into account the ease of assembly and maintenance. During assembly, flexible ribbon cables can be easily arranged and connected through these notches, reducing assembly time and complexity. When maintaining or replacing circuit boards, the ribbon cable notches also provide convenient access, allowing flexible ribbon cables to be easily rearranged or adjusted without causing unnecessary interference to other components.

[0087] In some cases, the first annular beam 21 and the second annular beam 22 are spaced apart, and the support beam 23 is distributed circumferentially along the first annular beam 21 and the second annular beam 22, forming a hollow structure of the capsule core support 2, and the battery is installed inside the capsule core support 2.

[0088] Please refer to Figure 6 , Figure 6 This is a positioning diagram of the axial positioning structure of the bracket and housing of the dual-lens capsule endoscope provided in the embodiments of this application.

[0089] In some embodiments, the capsule shell 1 is provided with a limiting structure 11, which is located on the side of the capsule shell 1 facing the capsule core support 2. The limiting structure 11 cooperates with a pair of adjacent support beams 23 to achieve circumferential positioning of the capsule core support 2 relative to the capsule shell 1.

[0090] In this embodiment, this design ensures that during the insertion of the capsule core support 2 into the capsule shell 1, the capsule core support 2 can only be advanced in a specific direction and cannot rotate. Specifically, the insertion of the capsule core support 2 must be carried out with a pair of adjacent support beams 23 engaged in the limiting structure 11. Only in this way can the capsule core support 2 be correctly pushed into the capsule shell 1.

[0091] Through the cooperation of the limiting structure 11 and the supporting beam 23, the position of the capsule core support 2 within the capsule shell 1 is precisely defined, thereby achieving circumferential positioning. This circumferential positioning, combined with the axial positioning achieved by the first mating structure 3, forms a dual positioning mechanism. Axial positioning ensures the longitudinal stability of the capsule core support 2 within the capsule shell 1, while circumferential positioning prevents the capsule core support 2 from rotating or shifting laterally. This dual positioning mechanism not only improves the installation accuracy of the capsule core support 2 within the capsule shell 1 but also enhances the structural stability and reliability of the entire dual-lens capsule endoscope.

[0092] In practical applications, this dual positioning mechanism effectively prevents the capsule core support 2 from shifting or rotating due to external forces during assembly and use, thus ensuring the normal operation of the endoscope system. Furthermore, this design improves the efficiency and accuracy of the assembly process, reducing the risk of failure due to positional deviations. Through precise axial and circumferential positioning, the capsule core support 2 stably supports key components of the endoscope system, such as circuit boards and optical parts, thereby guaranteeing the high performance and high reliability of the dual-lens capsule endoscope.

[0093] This application also provides a dual-lens capsule endoscope, including the aforementioned bracket and housing axial positioning structure.
