[0002] An endoscope system is a commonly used medical device that allows direct access to human cavities for examination, providing doctors with comprehensive diagnostic information. An endoscope system includes an endoscope and a camera. The endoscope is inserted into the cavity to transmit light into and receive light from the cavity. The endoscope is also connected to the camera, which captures video or images based on the light received from the cavity by the endoscope. The endoscope system also includes a camera control unit, which processes the video or images captured by the camera and displays or stores the processed data.
[0003] In related technologies, an endoscope and a camera are connected via an optical coupler, which releasably couples the endoscope to the camera. The optical coupler may include optical components for focusing light received from the endoscope onto an imaging sensor assembly in the camera. To provide this focusing capability, the coupler may include one or more optical components, such as one or more lenses or prisms, which may be movable relative to the camera, endoscope, or both to change the focal length.
[0004] In related technologies, the mounting base for optical couplers includes a lens barrel for mounting optical components and a base for mounting clamps. Typically, the lens barrel and base are separate components, connected by threads. However, the inventors have discovered that optical couplers in related technologies suffer from sealing issues, and assembly errors exist between the lens barrel and the base, affecting the reliability of the optical coupler. Therefore, providing an optical coupler with good sealing performance and minimal assembly errors is a technical problem urgently needing to be solved by those skilled in the art.

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0028] In the various embodiments of this application, "near end" and "far end" refer to the distance of each component from the user in the usage environment. The end closer to the user is designated as the "near end", and the end farther from the user is designated as the "far end".
[0029] In related technologies, the lens barrel for mounting optical components and the base for mounting clamps are separate components. They are connected by threads, but gaps may exist at the joint, resulting in insufficient sealing. In addition, optical couplers are valuable instruments that need to be reused. During sterilization, the sterilization medium can easily enter the lens barrel, causing damage to the optical components inside. Furthermore, optical couplers are precision instruments, and the assembly of the separate lens barrel and base may have errors. The cumulative effect of multiple errors on the entire optical coupler will result in a large overall assembly error, reduced coaxiality of the optical components, and affected image quality.
[0030] To this end, this application provides a mounting base in which a first mounting body for mounting optical components and a second mounting body for mounting clamp components are integrally formed. This reduces the number of steps required to assemble the first and second mounting bodies when assembling the optical coupler, eliminates potential sealing issues at the connection between the first and second mounting bodies, and also eliminates assembly errors between the first and second mounting bodies.
[0031] The following is in conjunction with the appendix Figures 1 to 8The mounting base, optical coupler, and endoscope system provided in this application will be described in detail through specific embodiments and application scenarios.
[0032] The first aspect of this embodiment describes the mounting base in detail.
[0033] The mounting base in this embodiment is used in an optical coupler. The optical coupler is a device that connects an endoscope and a camera, used to achieve signal transmission between the endoscope and the camera. The optical coupler is particularly used to connect the eyepiece cover 600 of the endoscope. Specifically, the distal end of the endoscope is inserted into the cavity to be inspected, and the proximal end of the endoscope is connected to the camera via the optical coupler.
[0034] The mounting base in this embodiment includes a first mounting base 110 and a second mounting base 120, as follows: Figures 6-8 As shown. The first mounting body 110 and the second mounting body 120 have mounting chambers 130 that communicate with each other. The mounting chambers 130 are used to accommodate the optical assembly 200, such as... Figures 6-8 As shown. For example, the optical assembly 200 includes a first lens 210, a second lens 220, a third lens 230, and a fourth lens 240. The first lens 210 is mounted within the mounting chamber 130 of the second mounting base 120, and the second lens 220, third lens 230, and fourth lens 240 are mounted within the mounting chamber 130 of the first mounting base 110, as shown. Figure 5 As shown. The first lens 210, the second lens 220, the third lens 230, and the fourth lens 240 are one or more of lenses, prisms, etc. For example, the second lens 220, the third lens 230, and the fourth lens 240 can move back and forth along the axis of the mounting base to adjust the image size.
[0035] In some embodiments, an inner cylinder 111 is installed inside the mounting chamber 130 of the first mounting base 110, such as... Figure 3 As shown. Multiple first guide grooves 111a are provided on the wall surface of the inner cylinder 111. The first guide grooves 111a are inclined grooves. First locking posts 221 are provided on both sides of the second lens 220, second locking posts 231 are provided on both sides of the third lens 230, and third locking posts 241 are provided on both sides of the fourth lens 240. The first locking posts 221, second locking posts 231, and third locking posts 241 are engaged within the first guide grooves 111a, as shown. Figure 3 and Figure 5 As shown.
[0036] In some embodiments, a second guide groove 112 is also provided on the wall surface of the first mounting base 110, such as... Figures 5-8As shown. The second guide groove 112 is an arc-shaped groove distributed along the circumferential direction of the wall of the first mounting base 110. A fourth locking post 410 is provided on the knob 400. The fourth locking post 410 is locked into the second guide groove 112, and at the same time, the fourth locking post 410 is also fixedly connected to the inner cylinder 111, as shown. Figure 5 As shown ( Figure 5 exist Figure 3 Based on this, the inner cylinder 111 is hidden. When the knob 400 is turned, the fourth locking pin 410 slides in the second guide groove 112; at the same time, the fourth locking pin 410 can drive the inner cylinder 111 to rotate; through the rotation of the inner cylinder 111, the first locking pin 221, the second locking pin 231 and / or the third locking pin 241 can slide in the first guide groove 111a, thereby adjusting the distance between each lens to adjust the image size.
[0037] In some embodiments, the second mounting base 120 is also used to mount the clamp assembly 300, such as Figure 3 As shown. Exemplarily, the second mounting base 120 is further provided with a housing 123, which is disposed outside the clamp assembly 300, such as... Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown. Figure 1 and Figure 2 As shown, the clamp assembly 300 can be used to clamp the eyepiece cover 600 at the proximal end of the endoscope, so that the eyepiece cover 600 can be snapped onto the optical coupler or removed, thereby realizing the coupling or separation of the endoscope and the camera.
[0038] In some embodiments, the first mounting base 110 and the second mounting base 120 are an integral structure, such as... Figures 6-8 As shown. Figures 6-8 As shown, the second mounting base 120 is located at the end of the first mounting base 110. The second mounting base 120 and the first mounting base 110 are an integral structure, that is, the second mounting base 120 and the first mounting base 110 are a single, inseparable unit. For example, the second mounting base 120 and the first mounting base 110 can be integrally molded by injection molding or other methods.
[0039] In this embodiment, the mounting base has an integral structure where the first mounting body 110 for mounting the optical component 200 and the second mounting body 120 for mounting the clamp assembly 300 are integrated. Compared to a structure where the lens barrel and clamp are separate, the mounting base of this embodiment can reduce the steps of assembling the first mounting body 110 and the second mounting body 120 when assembling the optical coupler. It can also eliminate the sealing problems at the connection between the first mounting body 110 and the second mounting body 120, and eliminate the assembly errors between the first mounting body 110 and the second mounting body 120.
[0040] As can be seen, the mounting base of this embodiment, when used for optical couplers, can improve the sealing performance of the optical coupler and the coaxiality of the optical component 200, and can also simplify the assembly steps of the optical coupler. It can solve the technical problems of sealing hazards and large assembly errors in optical couplers in related technologies.
[0041] In addition, when the mounting base of this embodiment is used for an optical coupler, the first mounting body 110 and the second mounting body 120 are an integral structure, which can improve the integration and compactness of the optical coupler.
[0042] In some embodiments, the connection between the first mounting body 110 and the second mounting body 120 has a reinforcing structure 140, such as... Figure 4 and Figure 8 As shown. In this embodiment, the mounting base, through the reinforcement structure 140, can improve the strength of the connection between the first mounting body 110 and the second mounting body 120, thereby improving the damage resistance of the mounting base.
[0043] In some embodiments, the reinforcing structure 140 is an integral structure with the first mounting base 110 and / or the second mounting base 120. For example, the reinforcing structure 140 and the first mounting base 110 and / or the second mounting base 120 can be integrally molded using methods such as injection molding. In this embodiment, the mounting base, with its reinforcing structure 140 and the first mounting base 110 and / or the second mounting base 120 being an integral structure, improves the damage resistance of the mounting base without requiring additional installation steps for the optical coupler.
[0044] In some embodiments, the inner diameter and / or outer diameter of the first mounting body 110 is smaller than the inner diameter and / or outer diameter of the second mounting body 120, and the first mounting body 110 and the second mounting body 120 are connected by a connecting portion, which is formed as a reinforcing structure 140, such as... Figure 4 and Figure 8 As shown. Figure 8 As shown, the inner and outer diameters of the first mounting base 110 are smaller than those of the second mounting base 120, so that the inner and outer wall surfaces of the first mounting base 110 and the second mounting base 120 are not on the same plane. When the first mounting base 110 and the second mounting base 120 are connected by the connecting part, a bending structure is formed between the first mounting base 110, the connecting part and the second mounting base 120, thereby improving the damage resistance of the mounting base.
[0045] In some embodiments, the thickness of the connecting portion is greater than the thickness of the first mounting base 110 or the second mounting base 120; and / or the height of the connecting portion between the first mounting base 110 and the second mounting base 120 is greater than the thickness of the first mounting base 110 or the second mounting base 120. This ensures the strength of the connection between the first mounting base 110 and the second mounting base 120.
[0046] Not limited to this, a reinforcing rib can be provided at the connection between the first mounting base 110 and the second mounting base 120. The strength of the connection between the first mounting base 110 and the second mounting base 120 can also be improved by the reinforcing rib, thereby improving the damage resistance of the mounting base.
[0047] In some embodiments, the second mounting base 120 is provided with an air hole 121, which is used to communicate the mounting chamber 130 on the second mounting base 120 with the outside. Figures 3-8 As shown. The vent 121 prevents the first lens 210 located inside the second mounting base 120 from fogging.
[0048] For example, a plurality of air holes 121 are provided along the circumferential direction of the second mounting base 120, and a fixing part 124 is provided between two adjacent air holes 121, such as... Figure 6 and Figure 7 As shown. The fixing part 124 can further enhance the strength of the mounting base.
[0049] In some embodiments, the vent 121 is located on the side of the second mounting base 120 near the reinforcing structure 140. The presence of the vent 121 reduces the strength of the mounting base. By placing the vent 121 on the side of the second mounting base 120 near the reinforcing structure 140, the reduced strength can be compensated for by the reinforcing structure 140.
[0050] In some embodiments, the mounting base further includes a stop 150, such as Figure 4 and Figure 8 As shown. A stop 150 is provided at the reinforcing structure 140, and a sealing cavity 160 is formed between the stop 150 and the knob 400 of the optical coupler. The sealing cavity 160 is used to install the sealing element 500. Figure 4 and Figure 8 A schematic diagram is shown showing the stop portion 150 located at the connecting portion. In this embodiment, the mounting base, through the provision of the stop portion 150, can block the seal 500 to enhance its sealing effect. Furthermore, the stop portion 150 is located at the reinforcing structure 140, thereby increasing the strength of the reinforcing structure 140. Correspondingly, the reinforcing structure 140 also enhances the strength of the stop portion 150, further ensuring the sealing effect of the seal 500.
[0051] In some embodiments, the stop portion 150 is also connected to the fixing portion 124, such as... Figure 6 As shown. This further enhances the strength of the stop portion 150 and the fixing portion 124, improving their damage resistance.
[0052] In some embodiments, the projection of the stop portion 150 is located at the reinforcing structure 140 along the radial direction of the first mounting body 110 and / or the second mounting body 120, such as... Figure 4 and Figure 8 As shown. Figure 4 and Figure 8 The stop portion 150 extends from the edge of the connecting portion in a direction away from the mounting chamber 130, so that the stop portion 150 and the connecting portion at least partially overlap in the radial direction of the first mounting body 110 and / or the second mounting body 120. This not only enhances the strength of both but also prevents the mounting base from being too long in the axial direction.
[0053] In some embodiments, the stop portion 150 is a closed annular sheet structure, and the stop portion 150 and the reinforcing structure 140 are an integral structure, such as... Figure 6 As shown. In this embodiment, the mounting base is provided with a stop portion 150 in the entire circumferential direction of the reinforcing structure 140, which can ensure the reliability of the stop portion 150 in blocking the seal 500; in addition, the stop portion 150 and the reinforcing structure 140 are an integral structure, which enhances the strength of the stop portion 150 and the reinforcing structure 140 without the need for additional installation steps of the optical coupler.
[0054] In some embodiments, the inner wall of the second mounting base 120 is provided with a groove 122, and the groove 122 is located on the second mounting base 120 near the end of the reinforcing structure 140, such as... Figure 4 and Figure 8 As shown. For example, the groove 122 can also be a relief groove. The groove 122 is beneficial for the machining and forming of the second mounting body 120 and also for the release of stress on the mounting base. On the other hand, the setting of the groove 122 reduces the strength of the second mounting body 120. By setting the groove 122 on the end of the second mounting body 120 near the reinforcing structure 140, the increased strength at the reinforcing structure 140 can compensate for the reduced strength of the second mounting body 120 caused by the groove 122, so that the strength of the second mounting body 120 is not affected.
[0055] The second aspect of this embodiment describes the optical coupler in detail.
[0056] The optical coupler of this embodiment includes a mounting base 100, an optical component 200, a clamping assembly 300, and a knob 400. The optical component 200 and the clamping assembly 300 are mounted on the mounting base 100. The knob 400 is rotatably mounted on the mounting base 100 and is used to control the position of the optical component 200, such as... Figures 1-5 As shown. The mounting base 100 is the mounting base for any of the technical solutions in the first aspect of this embodiment. The structures of the optical component 200, the clamp component 300, and the knob 400 can be the same as those in the prior art, and will not be described again here.
[0057] The optical coupler of this embodiment has a mounting base for any of the technical solutions in this embodiment, which can improve the sealing performance of the optical coupler and the coaxiality of the optical component 200, and also simplify the assembly steps of the optical coupler.
[0058] The third aspect of this embodiment provides a detailed description of the endoscope system.
[0059] The endoscope system of this embodiment includes an endoscope, a camera, and an optical coupler. The optical coupler is used to detachably couple the endoscope to the camera. The optical coupler is the optical coupler of any of the technical solutions in the second aspect of this embodiment. The structure of the endoscope and the camera can be the same as that of the prior art, and will not be described again here. For example, the endoscope is a rigid endoscope, and the optical coupler is used to snap the eyepiece cover 600 of the endoscope, thereby coupling the endoscope to the camera.
[0060] The endoscope system of this embodiment has an optical coupler according to any of the technical solutions in this embodiment, thereby improving the performance of the endoscope system of this embodiment.
