DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme of the utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope protected by the utility model.

[0029] The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or chronological sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second" and the like are generally of a kind, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0030] In the embodiments of the present application, "proximal end" and "distal end" refer to the relative position of each component to the user in the use environment, wherein the end closer to the user is designated as "proximal end", and the end farther away from the user is designated as "distal end".

[0031] The optical coupler in the related art sets an inclined sliding groove on the shell, and the clamp assembly includes a plurality of clamping pieces, the fixed end of the clamping piece is mounted on the base, and the clamping end is slidingly arranged in the inclined groove. By rotating the shell, the clamping end of the clamping piece can be driven to move in the radial direction of the base through the circumferential movement of the inclined sliding groove, so as to realize the fixing or dismounting of the eyepiece. The optical coupler of this structure, the clamping end of the clamping piece only has radial movement during clamping, and only the clamping effect on the eyepiece can be achieved, lacking the effect of assisting the centering of the eyepiece.

[0032] To this end, the application provides an auxiliary eyepiece centering clamping mechanism, which can drive the eyepiece cover to produce a slight rotation through the radial movement and circumferential movement of the clamping piece to achieve the effect of auxiliary eyepiece centering.

[0033] The application will be described in detail below with reference to the accompanying drawings Figures 1 to 9 The auxiliary eyepiece centering clamping mechanism, the optical coupler and the endoscope system provided by the application will be described in detail below with reference to specific embodiments and application scenarios.

[0034] The first aspect of the embodiment describes the auxiliary eyepiece centering clamping mechanism in detail.

[0035] The auxiliary eyepiece centering clamping mechanism of the embodiment is used in the optical coupler. The structure of the optical coupler is shown in Figure 1 and Figure 2 . The optical coupler is a device for connecting the endoscope and the camera and is used to realize signal transmission between the endoscope and the camera. Specifically, the distal end of the endoscope is used to be inserted into the cavity to be detected, and the proximal end of the endoscope is connected to the camera through the optical coupler. The clamping mechanism is used to clamp the endoscope to realize stable connection between the endoscope and the camera. The clamping mechanism is particularly used to clamp the eyepiece cover 300 of the endoscope to realize the connection between the endoscope and the camera, as shown in Figure 1 .

[0036] The auxiliary eyepiece centering clamping mechanism of the embodiment includes a mounting base 110. The mounting base 110 is used to provide a mounting basis for the remaining components. For example, the mounting base 110 is used to provide a mounting basis for the clamp assembly, the housing 130 and the driving assembly 140, as shown in Figure 2 and Figure 3 . In some embodiments, the mounting base 110 is provided with a guide groove 111, which is a straight linear groove. As shown in Figure 7 , the guide groove 111 of the embodiment is a straight linear groove, which means that the path of the guide groove 111 from one end to the other end is a straight line, and the distance of the guide groove 111 from the inner wall of the mounting base 110 is different from one end to the other end.

[0037] The auxiliary eyepiece centering clamping mechanism of the embodiment also includes a clamp assembly. The clamp assembly is used to clamp the eyepiece cover 300. In some embodiments, the clamp assembly includes at least two clamps 121. For example, the clamp assembly includes three clamps 121, which are distributed along the circumferential direction of the mounting base 110, so that the circumferential direction of the eyepiece cover 300 can be clamped by the three clamps 121, as shown in Figure 3 .

[0038] As shown in Figure 3As shown, the clamp 121 has two ends, one of which is a clamping end 1211, and the clamping ends 1211 of a plurality of clamps 121 are collectively used to clamp the ocular cover 300; the other is a fixed end 1212, and the fixed end 1212 is used to fix the clamp 121. In some embodiments, the clamping end 1211 is slidably mounted in the guide groove 111. The clamp assembly is further provided with a shell 130, and the fixed end 1212 is fixedly connected with the shell 130.

[0039] The ocular centering and clamping mechanism of the embodiment further includes a driving assembly 140, as shown. Figure 3 The driving assembly 140 is used to drive the clamp assembly to act. In some embodiments, the driving assembly 140 is arranged on the mounting base 110, and the driving assembly 140 is used to drive the shell 130 to rotate, so that the clamp 121 can be driven to rotate through the rotation of the shell 130, so that the clamp assembly has an open state and a closed state.

[0040] For example, when the driving assembly 140 drives the shell 130 to rotate in a first direction, the clamping end 1211 of the clamp 121 moves towards the center of the mounting base 110, so that the operation of clamping the ocular cover 300 can be realized; on the contrary, when the driving assembly 140 drives the shell 130 to rotate in a second direction, the clamping end 1211 of the clamp 121 moves away from the center of the mounting base 110, so that the ocular cover 300 can be disassembled. The second direction is opposite to the first direction. For example, the first direction is counterclockwise as shown, and the second direction is clockwise as shown. Figure 3 Figure 3

[0041] The ocular centering and clamping mechanism of the embodiment can drive the shell 130 to rotate through the driving assembly 140, so that the clamp 121 can be driven to rotate in the circumferential direction through the rotation of the shell 130. Taking the fixed ocular cover 300 as an example, in the process of rotating in the circumferential direction, the clamping end 1211 of the clamp 121 can also be driven to move in the radial direction through the cooperation of the clamping end 1211 and the guide groove 111, so that not only the ocular cover 300 can be clamped through the movement of the clamp 121 in the radial direction, but also the ocular cover 300 can be driven to rotate through the movement of the clamp 121 in the circumferential direction and the radial direction, so as to realize the effect of centering the ocular cover 300, and solve the problem that the optical coupler in the related art cannot realize the auxiliary ocular centering.

[0042] ​​In addition, the guide groove 111 is a straight inclined groove, which is beneficial to drive the clamping end 1211 to move along the radial direction when the housing 130 drives the clamp 121 to rotate along the circumferential direction. Moreover, the inclined groove is straight, which is beneficial to reduce the sliding resistance of the clamping end 1211 in the guide groove 111, so as to be easy to operate when exerting force on the driving assembly 140, without the need of too large force to drive the housing 130 to rotate.

[0043] In some embodiments, the clamping end 1211 is provided with a first protruding column 1213, which is installed in the guide groove 111, as shown in Figure 3 and Figure 8 Preferably, the outer diameter of the first protruding column 1213 is less than or equal to the opening width of the guide groove 111, so that the first protruding column 1213 is easy to slide in the guide groove 111, and the sliding resistance of the first protruding column 1213 in the guide groove 111 is reduced.

[0044] In some embodiments, the guide groove 111 has a first end and a second end. The first end is the position of the first protruding column 1213 in the guide groove 111 when the clamp assembly is in the open state, and the second end is the position of the first protruding column 1213 in the guide groove 111 when the clamp assembly is in the closed state. The distance between the guide groove 111 and the inner wall of the mounting base 110 gradually decreases from the first end to the second end, so that the clamping end 1211 can be driven to move along the radial direction by the guide groove 111 when the clamp 121 rotates along the circumferential direction.

[0045] It should be noted that the first end and the second end do not necessarily refer to the end positions of the guide groove 111, but can also be any positions in the guide groove 111.

[0046] In some embodiments, one of the fixed end 1212 and the housing 130 is provided with a second protruding column 1214, and the other one is provided with a mounting hole 131, and the second protruding column 1214 is fixedly installed in the mounting hole 131. For example, the second protruding column 1214 is in interference fit with the mounting hole 131, so as to realize the fixed connection between the housing 130 and the clamp 121. Figure 4 A schematic view of the housing 130 provided with the mounting hole 131 is shown, Figure 8 and a schematic view of the fixed end 1212 provided with the second protruding column 1214 is shown.

[0047] In some embodiments, the mounting base 110 has a mounting cavity 112 penetrating along the axial direction, as shown in Figure 7As shown. The mounting chamber 112 is used for accommodating the optical assembly, and the mounting base 110 is an integral structure, and the guide groove 111 is located on the end face of the mounting base 110. The mounting base 110 can be used not only for mounting the clamp assembly, but also for mounting the optical assembly, and the part of the mounting base 110 for mounting the clamp assembly and the part for mounting the optical assembly are an integral structure, as shown. Figure 7 For example, the mounting base 110 can be integrally formed by injection molding or the like.

[0048] The clamp mechanism of the embodiment, the mounting base 110 is an integral structure, which can reduce the steps of matching the part for mounting the clamp assembly and the part for mounting the optical assembly when assembling the optical coupler, and eliminate the assembly error; at the same time, it can also eliminate the sealing hidden danger existing at the connection between the part for mounting the clamp assembly and the part for mounting the optical assembly; in addition, it can also improve the integration and compactness of the optical coupler.

[0049] Not limited to this, the mounting base 110 can also be a split structure. The mounting base 110 includes a seat body for mounting the clamp assembly and a lens barrel for mounting the optical assembly. The seat body and the lens barrel are connected by threads.

[0050] In some embodiments, the driving assembly 140 includes a sliding block 141 and a first knob 142, as shown in Figure 3 、 Figure 5 and Figure 9 . The sliding block 141 is slidably mounted on the mounting base 110, and the sliding block 141 is also fixedly connected with the housing 130. For example, the sliding block 141 is fixedly connected with the housing 130 through the fixing piece 132, as shown in Figure 6 . The first knob 142 is fixedly connected with the sliding block 141, and the first knob 142 is used to drive the sliding block 141 to slide. For example, the first knob 142 is cylindrical, and the first knob 142 and the sliding block 141 are connected by thread cooperation. When force is applied to the first knob 142, the first knob 142 can drive the sliding block 141 to move, so that the movement of the sliding block 141 can drive the housing 130 to move, and then drive the clamp 121 to rotate.

[0051] In some embodiments, the driving assembly 140 further includes an elastic piece 143, as shown in Figure 3 、 Figure 5 and Figure 6 . The elastic piece 143 is located at the end of the sliding block 141, and based on the sliding of the sliding block 141, the elastic piece 143 can be elastically deformed. For example, the elastic piece 143 is a spring. The elastic deformation of the elastic piece 143 can be from the natural state to the compressed state, or from the natural state to the stretched state, which is not limited here.

[0052] Taking the elastic element 143 located in front of the slider 141 in the sliding direction as an example, when no force is applied to the first switch 142, the elastic element 143 is in its natural state. By pressing the slider 141, the elastic element 143 can be compressed. Conversely, when the force applied to the first switch 142 is released, the restoring force of the elastic element 143 can be applied to the slider 141, causing the slider 141 to return to its original position.

[0053] In some embodiments, the elastic element 143 and the first toggle switch 142 are located at the same end of the slider 141, making the distance between the first toggle switch 142 and the elastic element 143 smaller. This facilitates the transmission of the force applied to the first toggle switch 142 to the elastic element 143, thereby improving the responsiveness of the elastic element 143. Figure 6 As shown, when the elastic element 143 is located at the front end of the slider 141, the first dial 142 is fixed on the end of the slider 141 near the elastic element 143.

[0054] In some embodiments, the housing 130 is also provided with a limiting groove 133, such as Figure 2 As shown. The drive assembly 140 also includes a second toggle switch 144, which is located within the limiting groove 133 and is also fixedly connected to the mounting base 110, as shown. Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown. By cooperating with the second dial 144 and the limiting groove 133, the displacement of the outer shell 130 in the circumferential direction of the mounting base 110 can be limited, thereby limiting the displacement of the slider 141 in the circumferential direction of the mounting base 110.

[0055] In some embodiments, the mounting base 110 is provided with a mounting groove 113, and the slider 141 and the elastic element 143 are installed in the mounting groove 113, such as... Figure 3 , Figure 5 and Figure 6 As shown. The end of the slider 141 furthest from the elastic element 143 has a gap 1131 between it and the sidewall of the mounting groove 113, as... Figure 6 As shown. For example, the arc length of the mounting groove 113 is greater than the sum of the arc length of the slider 141 and the initial length of the elastic member 143, so that when one end of the elastic member 143 abuts against the inner wall of one side of the mounting groove 113, a gap 1131 can be formed between the other end of the slider 141 and the inner wall of the other side of the mounting groove 113, as shown. Figure 6 As shown. The initial state of the elastic element 143 can be either a natural state or a compressed state.

[0056] The clamping mechanism of the embodiment has a gap 1131 between the end of the sliding block 141 away from the elastic member 143 and the side wall of the mounting groove 113. When the sliding block 141 and the elastic member 143 are placed in the mounting groove 113, the gap 1131 can provide a space for the sliding block 141, and after the sliding block 141 is moved to the gap 1131, the installation space of the elastic member 143 can be increased, so that the sliding block 141 does not cause extrusion to the elastic member 143 or the extrusion force caused by the sliding block 141 to the elastic member 143 is small, so that the elastic member 143 is not easy to fall out during installation.

[0057] The second aspect of the embodiment is used to describe the optical coupler in detail.

[0058] The optical coupler of the embodiment includes a clamping mechanism. The clamping mechanism is the auxiliary eyepiece centering clamping mechanism of any one of the first aspect of the embodiment.

[0059] The optical coupler of the embodiment further includes an optical mechanism. The optical mechanism is arranged on the mounting base 110 of the clamping mechanism. For example, the optical mechanism includes an optical assembly arranged in the mounting base 110 and a knob assembly 200 sleeved outside the mounting base 110, as shown in Figures 1 to 3 、 Figure 5 and Figure 6 The structures of the optical assembly and the knob assembly 200 can be the same as those of the prior art, and will not be described here.

[0060] The optical coupler of the embodiment has the auxiliary eyepiece centering clamping mechanism of any one of the first aspect of the embodiment, and when the endoscope is connected to the camera through the optical coupler, the centering effect of the eyepiece and the camera can be improved.

[0061] The third aspect of the embodiment is used to describe the endoscope system in detail.

[0062] The endoscope system of the 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 one of the second aspect of the embodiment. The structures of the endoscope and the camera can be the same as those of the prior art, and will not be described here. For example, the endoscope is a rigid scope.

[0063] The endoscope system of the embodiment has the optical coupler of any one of the first aspect of the embodiment, and when the endoscope is connected to the camera through the optical coupler, the centering effect of the eyepiece and the camera can be improved.

[0064] It should be noted that, in this document, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the presence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0065] Further, it is to be understood that the scope of the methods and apparatus of the present embodiments are not limited by the order of execution of the functions, as described in the examples, but can include performing the functions in other orders, or substantially concurrently, or in reverse order, such as described in the examples, and can also include adding, omitting, or combining various steps, and the like.
