Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an endoscope system and its fluid supply and fixation structure. Background Technology

[0002] Endoscopic systems play a vital role in modern medical diagnosis and treatment, providing doctors with direct visualization of lesions through internal surgical procedures. A fluid supply device is an indispensable component of any endoscopic system, primarily used to provide irrigation fluid to clean the lens or assist in surgical operations. To ensure the stability and reliability of the fluid supply device, it is typically equipped with a specialized fixing structure to securely mount it onto the endoscopic system. However, existing fluid supply fixing structures face several technical challenges during long-term use.

[0003] In traditional endoscopic systems, the fluid supply device is typically secured to the outer casing using screws or clips. While this method provides initial stability, frequent installation and removal, along with prolonged exposure to water vapor and liquids, can cause the device to loosen during use. Once loosened, the fluid supply device may shift or detach during surgery, affecting the endoscope's proper function and potentially posing a safety hazard to the patient. Utility Model Content

[0004] The purpose of this application is to provide a fluid supply fixing structure for an endoscope system, which achieves a firm fixation and stable installation of the fluid supply device, effectively solving the problem of instability of the fluid supply device caused by loose fixing structure in the prior art, and improving the reliability and safety of the endoscope system during use. Another purpose of this application is to provide an endoscope system.

[0005] To achieve the above objectives, this application provides a fluid supply and fixation structure for an endoscope system, comprising:

[0006] The housing has a mounting hole and a mating groove, wherein the mating groove is located on the side of the mounting hole facing the interior of the housing;

[0007] The connector has a container fixing position and a connecting hole. The connector is located outside the housing, and the connecting hole is oriented towards the mounting hole.

[0008] The fastener has a connecting body and a fixing body connected together. The connecting body passes through the mounting hole and connects with the mounting hole. The fixing body and the mating groove are engaged in the axial direction of the mounting hole.

[0009] In some embodiments, the connector includes:

[0010] A pair of mounting posts, each provided with the connecting hole, are spaced apart;

[0011] A connecting plate, one end of which is away from the housing is connected to a pair of mounting posts, and the connecting plate and the pair of mounting posts form the container fixing position.

[0012] In some embodiments, the liquid supply fixing structure further includes a guide member disposed on the connector and located in the container fixing position.

[0013] In some embodiments, the connector includes a connecting plate; the guide includes a guide rib, the guide rib being disposed on the side of the connecting plate facing the housing, and the extending direction of the guide rib being consistent with the installation direction of the liquid supply device.

[0014] In some embodiments, the liquid supply fixing structure further includes a positioning member, which is disposed on the connector and cooperates with the housing.

[0015] In some embodiments, the connector includes a mounting post; the positioning element includes at least two positioning pins, which are disposed on the side of the mounting post facing the housing and are symmetrical about the center of the connector.

[0016] In some embodiments, the connection hole is a blind hole; and / or,

[0017] The connector is threadedly connected to the connecting hole.

[0018] In some embodiments, the connector includes a connecting plate; the connecting plate is provided with a magnetic attraction portion located on the side of the connecting plate facing the housing.

[0019] In some embodiments, the contact surface between the fixing body and the mating groove is provided with anti-slip texture; and / or,

[0020] The liquid supply fixing structure also includes an elastic element, which is disposed between the fixing body and the mating groove.

[0021] This application also provides an endoscope system, including a liquid supply device and the aforementioned liquid supply fixation structure.

[0022] Compared to the aforementioned background technology, the liquid supply and fixing structure of the endoscope system provided in this application mainly includes a housing, a connector, and a fastener. The housing is provided with a mounting hole and a mating groove, with the mating groove located on the side of the mounting hole facing the inside of the housing. The connector is provided with a container fixing position and a connecting hole, with the connector located on the outside of the housing and the connecting hole facing the mounting hole. The fastener is provided with a connected connecting body and a fixing body, with the connecting body passing through the mounting hole and connecting to the connecting hole, and the fixing body and the mating groove mating in the axial direction of the mounting hole.

[0023] The fluid supply and fixing structure of the endoscope system provided in this application mainly includes a housing, a connector, and fasteners. The housing, as a basic support component, has mounting holes and mating grooves. The mating grooves are located on the side of the mounting holes facing inwards from the housing, providing internal space and a positioning reference for fixing the fasteners. The connectors are located outside the housing and have container fixing positions and connecting holes for fixing the fluid supply device. They are connected to the connector body of the fasteners through the connecting holes. The fasteners, through their connector bodies, pass through the mounting holes of the housing and connect with the connecting holes of the connectors. Simultaneously, their fixing bodies mate axially with the mating grooves of the housing within the mounting holes, forming a stable fixing relationship.

[0024] This structural design optimizes the stress and layout of the connectors, achieving a secure and stable installation of the liquid supply device. The connectors, located outside the housing, directly bear the weight and external forces of the liquid supply device, while their axial restraint from the housing is achieved through fasteners within mating grooves inside the housing. This "outer and inner" combination design allows the connectors to transfer external forces to the mating grooves inside the housing when under stress, effectively dispersing and offsetting the loosening effect of the liquid supply device on the connectors. Therefore, the fit between the fastener's connecting body and the connecting hole ensures a tight connection between the connector and the housing, while the axial fit between the fixing body and the mating groove further restricts the movement of the fasteners, enhancing the overall structural stability. This combined internal and external fixing method significantly improves the liquid supply device's resistance to loosening during use, effectively solving the problem of instability caused by loose fixing structures in existing technologies.

[0025] Based on the above structural and process descriptions, it can be seen that the fluid supply fixing structure of this endoscope system has at least the following beneficial effects: This fluid supply fixing structure achieves a firm fixation and stable installation of the fluid supply device, effectively solving the problem of instability of the fluid supply device caused by loose fixing structure in the prior art, and improving the reliability and safety of the endoscope system during use.

[0046] 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.

[0047] 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.

[0048] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the fluid supply and fixation structure of the endoscope system provided in an embodiment of this application. Figure 2 A schematic diagram of the fluid supply and fixation structure and fluid supply device of the endoscope system provided in the embodiments of this application.

[0049] This application provides a liquid supply fixing structure 10 for an endoscope system 100, which is mainly used to fix the liquid supply device 20.

[0050] Please refer to Figure 3 and Figure 4 , Figure 3 This is a cross-sectional view of the housing, connector, and fastener provided in an embodiment of this application. Figure 4 A cross-sectional view of the housing, connector, and fastener provided in an embodiment of this application from another perspective.

[0051] In one embodiment, the liquid supply fixing structure 10 provided in this application mainly includes a housing 1, a connector 2, and a fastener 3. The housing 1 is provided with a mounting hole 101 and a mating groove 102, with the mating groove 102 located on the side of the mounting hole 101 facing the inside of the housing 1. The connector 2 is provided with a container fixing position 201 and a connecting hole 202, with the connector 2 located outside the housing 1 and the connecting hole 202 facing the mounting hole 101. The fastener 3 is provided with a connecting body 301 and a fixing body 302 connected together. The connecting body 301 passes through the mounting hole 101 and connects to the connecting hole 202, while the fixing body 302 and the mating groove 102 are engaged axially in the mounting hole 101.

[0052] In existing technologies, the fluid supply device 20 of an endoscope system 100 is typically fixed to the housing using simple screws or clips. This conventional fixing method is prone to loosening during long-term use due to frequent loading and unloading operations and the corrosive effects of moisture and liquids. This can cause the fluid supply device 20 to shift position or even fall off during surgery, severely affecting the normal use of the endoscope system 100 and potentially posing a safety hazard to the patient. To address this problem, this application proposes an innovative fluid supply fixing structure 10.

[0053] The fluid supply and fixing structure 10 of the endoscope system 100 provided in this application mainly includes a housing 1, a connector 2, and a fastener 3. The housing 1, as a basic support component, has a mounting hole 101 and a mating groove 102. The mating groove 102 is located on the side of the mounting hole 101 facing inwards from the housing 1, providing internal space and a positioning reference for fixing the fastener 3. The connector 2 is located outside the housing 1, and has a container fixing position 201 and a connecting hole 202 for fixing the fluid supply device 20. It is connected to the connector body 301 of the fastener 3 through the connecting hole 202. The fastener 3 passes through the mounting hole 101 of the housing 1 via its connector body 301 and connects to the connecting hole 202 of the connector 2. Simultaneously, its fixing body 302 mates with the mating groove 102 of the housing 1 axially in the mounting hole 101, forming a stable fixing relationship.

[0054] This structural design optimizes the force and layout of the connector 2, achieving a secure fixation and stable installation of the liquid supply device 20. The connector 2, located outside the housing 1, directly bears the weight and external forces of the liquid supply device 20, while its axial restraint with the housing 1 is achieved through the fastener 3 within the mating groove 102 inside the housing 1. This "one outside, one inside" combination design allows the connector 2 to transfer external forces to the mating groove 102 inside the housing 1 when under stress, effectively dispersing and offsetting the loosening effect of the liquid supply device 20 on the connector 2. Therefore, the fit between the connecting body 301 and the connecting hole 202 of the fastener 3 ensures a tight connection between the connector 2 and the housing 1, while the axial fit between the fixing body 302 and the mating groove 102 further restricts the movement of the fastener 3, enhancing the overall structural stability. This combined internal and external fixing method balances the torques at the internal and external positions, significantly improving the anti-loosening ability of the liquid supply device 20 during use and effectively solving the problem of instability of the liquid supply device 20 caused by loose fixing structures in existing technologies.

[0055] Based on the above structural and process descriptions, it can be seen that the liquid supply fixing structure 10 of the endoscope system 100 has at least the following beneficial effects: the liquid supply fixing structure 10 achieves a firm fixation and stable installation of the liquid supply device 20, effectively solving the problem of instability of the liquid supply device 20 caused by loose fixing structure in the prior art, and improving the reliability and safety of the endoscope system 100 during use.

[0056] It should be noted that this embodiment does not limit the fixing method of the liquid supply fixing structure 10 and the liquid supply device 20. Typically, the container fixing position 201 of the connector 2 is used to fix the liquid supply device 20. The liquid supply device 20 referred to here can be simply the container itself, or it can be a combination of the container and auxiliary components that facilitate fixing the container in the container fixing position 201. The fixing method of the liquid supply device 20 in the container fixing position 201 can be a snap-fit ​​installation, for example, the liquid supply device 20 is snapped into the container fixing position 201 from top to bottom, or it can be other methods, not limited to wire harness fixing, snap-fit ​​fixing, adhesive bonding, or even simple support fixing, all of which should be within the scope of this embodiment. Because the core of this embodiment is to solve the problem of loosening of the fastener 3, the fixing method of the connector 2 and the liquid supply device 20 does not directly affect the solution to the loosening problem.

[0057] In some embodiments, the connector 301 is threadedly connected to the connector hole 202.

[0058] In this embodiment, the fastener 3 and the connector 2 are fixed by a threaded connection between the connector 301 and the connector hole 202. Specifically, the connector 301 has an external thread, while the connector hole 202 of the connector 2 has a matching internal thread. This threaded connection allows the fastener 3 to be firmly attached to the connector 2, thereby providing a stable fixing foundation for the liquid supply device.

[0059] The fastener 3's connector 301, which is screwed in from inside the housing 1, cleverly utilizes the structural features of an internal and external combination. The connector 2, located outside the housing 1, directly bears the weight of the liquid supply device and external forces. When the liquid supply device applies pressure to the connector 2 due to its own weight or external forces, the connector 2 experiences a downward force, and the threaded connection of the fastener 3 produces an interlocking effect due to this pressure. Specifically, the pressure from the liquid supply device causes the threads of the connector 301 to mesh more tightly with the internal threads of the connecting hole 202, further enhancing the stability of the connection.

[0060] This threaded connection design not only improves the connection's robustness but also effectively prevents loosening caused by external forces or vibrations. Since the fastener 3 is screwed in from inside the housing 1, the direction of its threaded connection is consistent with the direction of pressure applied by the liquid supply device, making the connector 301 more stable under stress and preventing easy loosening. This design fully utilizes the structural advantages of the internal and external combination, transforming the pressure from the liquid supply device into a factor that enhances connection stability, thereby further improving the reliability of the liquid supply fixing structure.

[0061] In some embodiments, the connection hole 202 is a blind hole.

[0062] In this embodiment, the connecting hole 202 is designed as a blind hole. This structural feature allows the fastener 3 to be screwed into the connector 2 from inside the housing 1 when it is fixedly connected to the connector 2, but it will not penetrate the connector 2; instead, it will be hidden inside it. This design not only achieves a firm connection between the fastener 3 and the connector 2, but also brings significant advantages in appearance and durability.

[0063] Because the connecting hole 202 is a blind hole, the fastener 3 will not be exposed on the outside of the connector 2 after installation. This means that the appearance of the connector 2 remains neat, without protruding parts or exposed threads, thus improving the overall aesthetics. This design is particularly suitable for medical devices with high aesthetic requirements, such as endoscope systems, as it ensures a clean and professional appearance of the device surface.

[0064] Furthermore, the design of concealing fastener 3 within connector 2 significantly enhances durability. In practical use, fastener 3 is not affected by external environmental factors such as liquid corrosion, impact, or friction due to its exposure, thereby reducing the risk of damage caused by external forces. This design effectively avoids scratches or damage that may occur to fastener 3 due to its exposure, further extending the service life of the liquid supply fixing structure.

[0065] Please refer to Figure 5 , Figure 5 This is a schematic diagram of a connector provided in an embodiment of this application.

[0066] In some embodiments, the connector 2 includes: a pair of mounting posts 203, each having a connecting hole 202, the pair of mounting posts 203 being spaced apart; and a connecting plate 204, one end of the connecting plate 204 away from the housing 1 being connected to the pair of mounting posts 203, the connecting plate 204 and the pair of mounting posts 203 forming a container fixing position 201.

[0067] In this embodiment, a pair of mounting posts 203 provide two independent connection points for the fastener 3. This dual-point support design forms a stable support structure at both ends of the container fixing position 201.

[0068] By employing a pair of mounting posts 203 as support points, the connector 2 provides a more stable foundation for the liquid supply device 20. This dual-point support structure, similar to a frame, effectively distributes the weight and external forces of the liquid supply device 20, avoiding the instability and loosening risks that may arise from single-point support. The connecting plate 204 further enhances the overall structural stability while providing a clear fixed position for the liquid supply device 20.

[0069] This design not only improves the structural strength of the connector 2, but also provides greater reliability for the fixation of the liquid supply device 20. In practical use, the liquid supply device 20 can be installed in the container fixing position 201 in various ways, and the dual-point support design ensures its stability under various operating conditions, thus providing strong support for the normal operation of the endoscope system.

[0070] In some cases, the liquid supply device 20 is suspended on the liquid supply fixing structure 10 by a snap-fit ​​installation. Optionally, the liquid supply device 20 is provided with a hook 7 with a flange at the upper end. The lower end of the hook 7 is inserted between the connecting plate 204 and a pair of mounting posts 203, so that while the connecting plate 204 is in contact with the side of the hook 7, the upper edge of the connecting plate 204 supports the flange of the hook 7.

[0071] Please refer to Figure 6 , Figure 6 This is a schematic diagram of the connector provided in an embodiment of this application from another perspective.

[0072] In some embodiments, the liquid supply fixing structure 10 further includes a guide 4, which is disposed on the connector 2 and located in the container fixing position 201.

[0073] In this embodiment, the main function of the guide 4 is to provide precise guidance for the installation process of the liquid supply device 20, ensuring that the liquid supply device 20 can be installed correctly and smoothly. When the liquid supply device 20 is installed using a snap-fit ​​method, the guide 4 can restrict the installation direction of the liquid supply device 20, so that it is accurately installed into the container fixing position 201 along a preset path.

[0074] Specifically, the guide component 4 not only guides the installation process but also further enhances the stability of the fluid supply device 20 after installation. By limiting the shaking of the fluid supply device 20 within the container fixing position 201, the guide component 4 effectively solves the problem of shaking caused by external forces or improper operation. This design is particularly important in practical use because the endoscopic system needs to maintain a high degree of stability and precision during surgery, and any shaking may affect the smooth progress of the operation.

[0075] Please refer to Figure 7 , Figure 7 This is a schematic diagram of the connector and liquid supply device provided in the embodiments of this application.

[0076] In some embodiments, the connector 2 includes a connecting plate 204; the guide 4 includes a guide rib 401, which is disposed on the side of the connecting plate 204 facing the housing 1, and the extending direction of the guide rib 401 is consistent with the installation direction of the liquid supply device 20.

[0077] In this embodiment, this design layout enables the guide rib 401 to play a key guiding role during the installation of the liquid supply device 20, especially when the liquid supply device 20 is installed using a snap-fit ​​method.

[0078] Specifically, the extension direction of the guide rib 401 should be consistent with the installation direction of the liquid supply device 20. The design of the guide rib 401 not only provides directional guidance during installation, but also further enhances the stability of the liquid supply device 20 after installation. For example, the guide rib 401 is used to cooperate with the guide groove 71 on the hook 7 of the liquid supply device 20. The guide groove 71 extends to the lower end of the hook 7. Therefore, when the hook 7 is inserted into the container fixing position 201, the guide groove 71 can be inserted into the guide rib 401 from its lower end opening, and move down along the guide rib 401 until the hook 7 abuts against the upper edge of the connecting plate 204, or the top wall of the guide groove 71 abuts against the top of the guide rib 401, or both abut against each other at the same time, so as to support the liquid supply device 20. Specifically, the width of the guide rib 401 is similar to the width of the limiting groove, thus effectively limiting the swaying of the hook 7 within the container fixing position 201, improving the stability of the liquid supply device 20 installation, and effectively solving the problem of swaying of the liquid supply device 20 caused by external forces or improper operation. This structural design enables the liquid supply device 20 to maintain high stability during use, avoiding the impact of swaying on the normal operation of the endoscope system.

[0079] Furthermore, the tight fit between the connecting plate 204 and the hook 7, as well as the support provided by the connecting plate 204 for the flange of the hook 7, further enhances the fixing strength of the liquid supply device 20 in the container fixing position 201. This design not only ensures the stability of the liquid supply device 20 after installation, but also improves the convenience and accuracy of installation through the guiding effect of the guide rib 401. Therefore, this embodiment optimizes the installation and fixing process of the liquid supply device 20 by combining the guide rib 401 with the connecting plate 204, significantly improving the overall performance and reliability of the liquid supply fixing structure 10.

[0080] In other embodiments, the guide 4 may also cooperate with a portion of the outer wall of the liquid supply device 20 for guidance, such as cooperating with the outer wall surface of the hook of the liquid supply device 20 for guidance, in which case the liquid supply device 20 does not need to be provided with the above-mentioned guide groove 71.

[0081] In some embodiments, the connector 2 includes a connecting plate 204; the connecting plate 204 is provided with a magnetic attraction part 2041, which is located on the side of the connecting plate 204 facing the housing 1.

[0082] In this embodiment, the structural design of the connector 2 is further optimized, specifically including a connecting plate 204, and a magnetic suction part 2041 is provided on the side of the connecting plate 204 facing the housing 1. The magnetic suction part 2041 can be made of magnetic material, and its main function is to attract the hook 7 on the liquid supply device 20 by magnetic force, thereby enhancing the fixing effect of the connecting plate 204 on the liquid supply device 20.

[0083] Specifically, the hook 7 of the liquid supply device 20 is made of a metal material that can be attracted by the magnetic attraction part 2041. When the liquid supply device 20 is inserted into the container fixing position 201 via a snap-fit ​​installation, the lower end of the hook 7 is inserted between the connecting plate 204 and a pair of mounting posts 203. At this time, the magnetic attraction part 2041 interacts with the hook 7, generating a magnetic attraction. This magnetic attraction not only helps the hook 7 to be accurately inserted and positioned, but also further enhances the bonding strength between the hook 7 and the connecting plate 204 after installation.

[0084] The design of the magnetic suction part 2041 significantly improves the fixing effect of the connecting plate 204 on the liquid supply device 20. On the one hand, the magnetic attraction ensures that the hook 7 is more stable during insertion, reducing shaking or misalignment caused by improper operation; on the other hand, after installation, the magnetic force can continue to act on the hook 7, further enhancing its tightness with the connecting plate 204, thereby improving the stability of the liquid supply device 20 in the container fixing position 201.

[0085] In some embodiments, the liquid supply fixing structure 10 further includes a positioning member 5, which is disposed on the connecting member 2 and cooperates with the housing 1.

[0086] In this embodiment, the liquid supply fixing structure 10 is further optimized by adding a positioning element 5. The positioning element 5 is set on the connector 2 and cooperates with the housing 1. Its core function is to accurately position the connector 2 to the correct position before the connector 2 is fixed to the housing 1 by the fastener 3.

[0087] During actual assembly, connector 2 needs to be precisely aligned with housing 1 to ensure that subsequent fasteners 3 can be installed smoothly and achieve a stable fixing effect. The design of positioning component 5 is precisely to solve this problem. By cooperating with housing 1, positioning component 5 can provide an initial positioning reference for connector 2, ensuring that connector 2 will not shift or misalign during installation.

[0088] Specifically, the positioning element 5 functions similarly to a "pre-fixing" device. Before the fastener 3 fully secures the connector 2, the positioning element 5, through its cooperation with the housing 1, holds the connector 2 in a relatively stable state. This pre-positioning function not only improves assembly efficiency but also reduces subsequent problems caused by installation errors, such as difficulty in installing the fastener 3 or a loose fit between the connector 2 and the housing 1.

[0089] Furthermore, the design of the positioning element 5 enhances the reliability and stability of the entire liquid supply fixing structure 10. By ensuring the precise position of the connector 2 during installation, the positioning element 5 provides a better fixing foundation for the fastener 3, further preventing loosening or shaking caused by inaccurate positioning of the connector 2.

[0090] In some embodiments, the connector 2 includes a mounting post 203; the positioning member 5 includes a positioning pin 501, which is located on the side of the mounting post 203 facing the housing 1.

[0091] In this embodiment, the structure of the connector 2 is further refined, specifically including a mounting post 203. Meanwhile, the positioning element 5 is specifically in the form of a positioning pin 501, and the positioning pin 501 is located on the side of the mounting post 203 facing the housing 1. This design achieves precise positioning of the connector 2 through the interlocking fit between the positioning pin 501 and the positioning hole on the housing 1.

[0092] Specifically, the function of the locating pin 501 is to fix the connector 2 in an accurate position before it is installed onto the housing 1. The housing 1 has a locating hole corresponding to the locating pin 501. When the connector 2 approaches the housing 1, the locating pin 501 inserts into the locating hole of the housing 1, forming a concave-convex fit. This fit ensures that the connector 2 will not shift or misalign during installation, providing a precise reference for the subsequent installation of the fastener 3.

[0093] By engaging the locating pin 501 with the locating hole in the housing 1, the connector 2 can be quickly and accurately aligned during installation. This design not only improves assembly efficiency but also reduces subsequent problems caused by installation errors, such as difficulty in installing the fastener 3 or loose fit between the connector 2 and the housing 1. Furthermore, the concave-convex fit of the locating pin 501 enhances the stability and reliability of the entire liquid supply fixing structure 10, ensuring that the connector 2 remains stable during installation and will not shift due to external forces.

[0094] In some embodiments, the positioning member 5 includes at least two positioning pins 501, which are located on the side of the mounting post 203 facing the housing 1 and are symmetrical about the center of the connector 2. By engaging at least two positioning pins 501 and being centrally symmetrical about the center of the connector 2, multi-directional precise positioning can be achieved. That is, the connector 2 will not translate or rotate relative to the housing 1 during installation, thereby improving positioning accuracy and thus improving the installation accuracy of the liquid supply device 20.

[0095] In some embodiments, the contact surface between the fixing body 302 and the mating groove 102 is provided with anti-slip texture.

[0096] In this embodiment, to further enhance the stability and reliability of the liquid supply fixing structure 10, anti-slip textures are provided on the contact surfaces of the fixing body 302 and the mating groove 102. Specifically, the surface of the mating groove 102 is provided with a first anti-slip texture 1021, while the surface of the fixing body 302 is provided with a second anti-slip texture 3021. This design effectively prevents the fastener 3 from loosening due to external forces during use by increasing the friction of the contact surfaces.

[0097] When the fixing body 302 of the fastener 3 is inserted into the mating groove 102 of the housing 1, the first anti-slip texture 1021 and the second anti-slip texture 3021 engage with each other, forming a high-friction contact state. This high-friction state not only effectively resists the axial and circumferential movement of the fastener 3 caused by the weight of the liquid supply device 20 or external forces, but also maintains a stable fixing effect during long-term use. Even in environments with frequent loading and unloading operations or exposure to moisture, the anti-slip texture design significantly reduces the risk of loosening.

[0098] Furthermore, by providing anti-slip textures on the fixing body 302 and the mating groove 102 respectively, this design also optimizes the contact area and pressure distribution between the fastener 3 and the housing 1. The cooperation between the first anti-slip texture 1021 and the second anti-slip texture 3021 can better disperse external forces and reduce local stress concentration, thereby extending the service life of the fastener 3 and the housing 1.

[0099] Please refer to Figure 8 , Figure 8 This is a schematic diagram of the housing, connector, and elastic element provided in the embodiments of this application.

[0100] In some embodiments, the liquid supply fixing structure 10 further includes an elastic element 6, which is disposed between the fixing body 302 and the mating groove 102.

[0101] In this embodiment, the liquid supply fixing structure 10 is further optimized by introducing the design of the elastic element 6. The elastic element 6 is disposed between the fixing body 302 and the mating groove 102, and its main function is to provide additional elastic support and buffering function for the connection between the fastener 3 and the housing 1.

[0102] Specifically, the presence of the elastic element 6 effectively addresses dimensional changes and stress concentration caused by temperature variations, mechanical vibrations, or external impacts. In actual use, the endoscope system may be subjected to various external forces, such as collisions during surgical procedures or vibrations during equipment movement. These external forces may cause slight loosening or displacement of the connection between the fastener 3 and the housing 1. By providing the elastic element 6 between the fixing body 302 and the mating groove 102, its elastic properties can be used to absorb and buffer these external forces, thereby maintaining a stable contact between the fastener 3 and the housing 1 and reducing the risk of loosening.

[0103] Furthermore, the elastic element 6 can also compensate for component deformation or wear caused by long-term use or environmental factors (such as temperature changes). For example, in high or low temperature environments, the thermal expansion and contraction of materials may cause changes in the fit clearance between the fastener 3 and the housing 1. The elastic deformation capability of the elastic element 6 can adapt to such dimensional changes, ensuring that the fixing body 302 and the mating groove 102 always maintain a tight contact, thereby maintaining the stability and reliability of the liquid supply fixing structure 10.

[0104] In some cases, the mounting hole 101 and the mating groove 102 are designed to form a special structural relationship. Specifically, the mounting hole 101 and the mating groove 102 are connected to form a complete hole structure. In this design, the mounting hole 101 can be regarded as the through part of the hole structure leading to one end of the connector 2, while the mating groove 102 is the flared part at the other end of the hole structure. This structural design allows the fastener 3 to smoothly pass through the mounting hole 101 and engage with the mating groove 102, thereby achieving the fixation of the connector 2.

[0105] Specifically, the flared portion of the mating groove 102 is tapered, with its larger diameter end facing inwards from the housing 1. This tapered design provides a unique mating method for the fixing body 302 of the fastener 3. Specifically, the fixing body 302 fits tightly against the tapered surface of the mating groove 102 on the side facing the mounting hole 101, which is also the location of the elastic element 6. This tight fit not only enhances the contact area between the fastener 3 and the housing 1, but also, through the guiding effect of the tapered surface, allows the fastener 3 to enter the mating groove 102 more stably during installation and achieve precise positioning.

[0106] As an optional design, the fixing body 302 is preferably flush with the inner wall surface of the housing 1 on the side opposite to the mounting hole 101. This design ensures that the outer surface of the fastener 3 is aligned with the inner wall surface of the housing 1 after installation, thus avoiding interference problems that may be caused by the fastener 3 protruding. At the same time, this flush design further enhances the aesthetics and integrity of the entire liquid supply fixing structure 10.

[0107] Through this special hole structure design, the mounting hole 101 and the mating groove 102 not only achieve stable installation of the fastener 3, but also further improve the stability and reliability of the liquid supply fixing structure 10 through the tight fit between the tapered mating groove 102 and the fixing body 302. This design not only optimizes the installation process of the fastener 3, but also provides a more stable fixing foundation for the liquid supply device 20, ensuring that it can maintain a good working condition during use.

[0108] Please refer to Figure 9 , Figure 9This is a schematic diagram of an endoscope system provided in an embodiment of this application.

[0109] This application also provides an endoscope system 100, including a liquid supply device 20 and any of the above-described liquid supply fixing structures 10.

[0110] The endoscope system 100 includes the above-mentioned liquid supply and fixation structure 10 and should have the beneficial effects of the above-mentioned liquid supply and fixation structure 10, which will not be described in detail here.

[0111] In some embodiments, the liquid supply device 20 includes a hook 7 that engages with the container fixing position 201 to attach to the liquid supply fixing structure 10.

[0112] In some embodiments, the connector 2 has a guide 4 on its inner wall facing the container fixing position 201, and the liquid supply device 20 has a guide groove 71 that cooperates with the guide 4. That is, by providing the guide groove 71, it avoids being positioned relative to the guide 4 when the liquid supply device 20 is inserted into the container fixing position 201. For example, the guide groove 71 is formed in the hook 7, that is, when the hook 7 is inserted into the container fixing position 201, the guide groove 71 can avoid being positioned relative to the guide 4 and cooperate with it for guidance.

[0113] In some cases, the housing 1 in the liquid supply fixing structure 10 can be the chassis of the main unit of the endoscope system 100, or it can be the chassis of the light source of the endoscope system 100. In particular, the liquid supply device 20 is fixed to the side of the chassis, that is, the left or right side of the housing 1. Optionally, the liquid supply device 20 is a water bottle.
