Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a clamping mechanism, an optical coupler, and an endoscope system. Background Technology

[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, the endoscope and camera are connected via an optical coupler, which releasably couples the endoscope to the camera. Specifically, the end of the optical coupler is equipped with a clamping assembly, which includes multiple openable and closable clamps. When the clamps are closed, they hold the endoscope in place to maintain a reliable connection between the endoscope and the camera; when the clamps are open, the endoscope can be removed. Furthermore, the opening and closing of the clamps is controlled by a toggle switch and a spring, with the toggle switch fixedly mounted on the housing or clamp base.

[0004] However, the inventors discovered that in related optical couplers (such as Chinese Patent CN217181341U), the toggle switch is block-shaped, specifically resembling a trapezoidal block structure, with its width on the side closer to the outer shell being greater than the width on the side farther from the outer shell. When fixing the toggle switch to the outer shell or clamp holder, screws are typically screwed in from inside the shell. This requires first aligning the toggle switch with the mounting holes on the shell or clamp holder, and then screwing the screws into the mounting holes. This installation process is not only cumbersome, but also presents challenges due to limited space and operational difficulty when screwing the screws in from inside the shell. Therefore, providing an optical coupler with a simple assembly process is a technical problem urgently needing to be solved by those skilled in the art. Utility Model Content

[0005] This utility model discloses a clamping mechanism, an optical coupler, and an endoscope system to solve the technical problems of cumbersome installation and difficult operation of the clamping components of optical couplers in related technologies.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] The first aspect of this utility model provides a clamping mechanism.

[0008] The present invention discloses a clamping mechanism for an optical coupler. The clamping mechanism includes: a mounting base for providing a mounting foundation; a clamp assembly including clamps slidably mounted on the mounting base and having an open and closed state; and a drive assembly including a slider and a first knob. The slider is slidably mounted on the mounting base and fixedly connected to the clamp assembly. The first knob drives the slider to slide, and its end has a first screw threadedly connected to the slider. The circumferential surface of the first knob is arc-shaped.

[0009] A second aspect of this invention provides an optical coupler.

[0010] The optical coupler of this utility model includes a clamping mechanism, which is the clamping mechanism described in any of the technical solutions of this utility model.

[0011] The third aspect of this invention provides an endoscope system.

[0012] The endoscope system of this utility model includes an endoscope, a camera, and an optical coupler. The optical coupler is the optical coupler described in any of the technical solutions of this utility model. The optical coupler is used to detachably couple the endoscope to the camera.

[0013] The technical solution adopted in this utility model can achieve the following beneficial effects:

[0014] Firstly, the clamping mechanism of this utility model includes a first dial for driving the clamp to slide, which is threadedly connected to the slider via a first screw at its end. When assembling the first dial, the first screw can be directly installed into the mounting hole on the slider, requiring only one operation. Compared with the existing technology which requires at least two steps for installation, this simplifies the installation process.

[0015] Secondly, in the clamping mechanism of this utility model, the first knob can be mounted on the slider from the outside of the mounting base, and its operating space is not restricted, making it easy to operate.

[0016] Thirdly, in the clamping mechanism of this utility model, the circumferential surface of the first knob is arc-shaped, so that the shape of the first knob is not affected by the tightness of the first screw. That is, the shape of the first knob is the same regardless of the depth to which the first screw is screwed in, so as not to affect the operator's feel of turning it, and it is also aesthetically pleasing. At the same time, the circumferential surface of the first knob is arc-shaped, which can accommodate more contact postures of the fingers. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] 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.

[0031] 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".

[0032] In related technologies, optical couplers use a block-shaped knob, specifically a trapezoidal block structure, with the width of the side closer to the housing being greater than the width of the side farther from the housing. When fixing the knob to the housing or clamp base, screws are usually screwed in from inside the housing to secure it. First, the knob needs to be aligned with the mounting holes on the housing or clamp base, and then the screws are screwed into the mounting holes. This installation process is not only cumbersome, but also difficult to operate due to the limited space when screwing the screws in from inside the housing.

[0033] Furthermore, the inventors considered integrating a screw structure into the toggle switch. This would allow for direct installation from outside the housing or clamp, simply screwing the switch into the mounting hole on the housing or clamp. However, because the switch is a block structure, it's difficult to ensure that the switch's surface is parallel to the end face of the housing or clamp after installation. This not only affects the operator's feel when turning the switch but also the overall aesthetics of the optical coupler.

[0034] To address this, this application provides a clamping mechanism. The end of the lever of the clamping mechanism has a screw, and the lever is threadedly connected to the carrier through the screw, which simplifies the installation process and reduces the installation difficulty. At the same time, the circumferential surface of the lever is arc-shaped, so that the shape of the lever is not affected by the tightness of the screw, and it can also accommodate more contact postures of the fingers.

[0035] The following is in conjunction with the appendix Figures 1 to 10 The clamping mechanism, optical coupler, and endoscope system provided in this application will be described in detail through specific embodiments and application scenarios.

[0036] The first aspect of this embodiment describes the clamping mechanism in detail.

[0037] The clamping mechanism in this embodiment is used in an optical coupler. The structure of the optical coupler is as follows: Figures 1-3 As shown. The optical coupler is a device that connects the endoscope and the camera, used to achieve signal transmission between the endoscope and the camera. 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. The clamping mechanism is used to clamp the endoscope to achieve a stable connection between the endoscope and the camera. The clamping mechanism is particularly used to clamp the eyepiece cover 300 of the endoscope to achieve the connection between the endoscope and the camera, such as... Figure 1 As shown.

[0038] The clamping mechanism in this embodiment includes a mounting base 110, a clamp assembly, and a drive assembly 130, such as Figures 4-6 As shown. Mounting base 110 provides a mounting base for the clamp assembly and drive assembly 130. That is, the clamp assembly and drive assembly 130 can be mounted on mounting base 110, as... Figures 4-6 As shown.

[0039] The clamp assembly includes clamps 121, which are slidably disposed on the mounting base 110 and have open and closed states. For example, there are at least two clamps 121, which are disposed on the end face of the mounting base 110 and are distributed along the circumferential direction of the mounting base 110 to form a ring structure. Figure 4 As shown. For example, by sliding the clamp 121, the size of the annular structure can be increased. At this time, the clamp 121 is in the open state, and the eyepiece cover 300 can be installed in the annular structure. Conversely, when the clamp 121 slides in the opposite direction, the clamp 121 resets, and the size of the annular structure shrinks to the initial size, so that the eyepiece cover 300 can be clamped by the annular structure formed by the clamp 121.

[0040] For example, such as Figure 4As shown, when clamp 121 slides clockwise, clamp 121 is in the open state; when clamp 121 slides counterclockwise, clamp 121 is in the closed state.

[0041] Not limited to this, the clamp assembly can also be in the open state initially.

[0042] The drive assembly 130 includes a slider 131 and a first toggle switch 132, such as Figures 4-6 As shown, slider 131 is slidably mounted on mounting base 110. Slider 131 is fixedly connected to clamp assembly, and first knob 132 is used to drive slider 131 to slide. Exemplarily, slider 131 is fixedly connected to clamp assembly via housing 122. When force is applied to first knob 132, slider 131 can be driven to slide, and the sliding of slider 131 can drive clamp assembly to slide, thereby allowing clamp assembly to switch between open and closed states. The force applied to first knob 132 can be the operator's pushing force and / or the restoring force of elastic components.

[0043] In some embodiments, the end of the first toggle switch 132 has a first screw 1321, which is threadedly connected to the slider 131, such as... Figure 6 and Figure 7 As shown. For example, the first screw 1321 is integrated into the end of the first dial 132, that is, the first dial 132 and the first screw 1321 are a single unit, as shown. Figure 6 and Figure 7 As shown. For example, as... Figure 10 As shown, the slider 131 has a first mounting hole 1313, and the first mounting hole 1313 has a threaded structure. The surface of the first screw 1321 has a threaded structure that matches the threaded structure (not shown in the figure). By screwing the first screw 1321 into the first mounting hole 1313, the first screw 1321 and the first mounting hole 1313 can be threadedly connected.

[0044] The threaded structure on the outer surface of the first screw 1321 and the threaded structure inside the first mounting hole 1313 are common threaded structures in the prior art, and are not shown in the figure.

[0045] In this embodiment, the clamping mechanism has a first dial 132 that is threadedly connected to the slider 131 via a first screw 1321 at its end. When assembling the first dial 132, the first screw 1321 can be directly installed into the first mounting hole 1313 on the slider 131, requiring only one step. Compared to the existing technology which requires at least two steps for installation, this simplifies the installation process. In addition, the first dial 132 can be installed onto the slider 131 from outside the mounting base 110, so its operating space is unrestricted and it is easy to operate.

[0046] In some embodiments, the circumferential surface of the first toggle switch 132 is curved, such as... Figures 1-7 As shown. Exemplarily, the first dial 132 has a cylindrical arc surface, making it operable in all directions. Compared to the block-shaped dials in the prior art, it can accommodate more finger contact postures. In the clamping mechanism of this embodiment, the circumferential surface of the first dial 132 is arc-shaped, which also makes the shape of the first dial 132 unaffected by the tightness of the first screw 1321. That is, the shape of the first dial 132 remains the same regardless of the depth to which the first screw 1321 is screwed in, thus not affecting the operator's feel when turning the dial, and also providing an aesthetically pleasing appearance.

[0047] In this embodiment, the first dial 132 is cylindrical. This can mean that the main body of the first dial 132 is cylindrical, and its end can be hemispherical or other structures. Figures 1-5 As shown.

[0048] In some embodiments, when the first toggle switch 132 is cylindrical and the outer diameter of the first screw 1321 is smaller than the outer diameter of the first toggle switch 132, the size of the first mounting hole 1313 opened on the slider 131 is smaller, which can reduce the impact on the strength of the slider 131. See also Figures 1-3 The first dial 132 is also surrounded by a housing 122. The first dial 132 passes through the housing 122. The outer diameter of the first screw 1321 is small, which makes the hole opened on the housing 122 smaller, which can reduce the impact on the strength of the housing 122 and also help improve the aesthetics.

[0049] In some embodiments, the drive assembly 130 further includes an elastic element 133, such as Figures 4-6 As shown. The elastic element 133 is located at the end of the slider 131. Based on the sliding of the slider 131, the elastic element 133 undergoes elastic deformation. For example, the elastic deformation of the elastic element 133 can be from a natural state to a compressed state or from a natural state to a stretched state, and there is no limitation here.

[0050] like Figure 6 As shown, when the elastic element 133 is in front of the sliding direction of the slider 131, by applying force to the first dial 132, the slider 131 can be driven to slide in the direction of the elastic element 133. The slider 131 can apply pressure to the elastic element 133, thereby making the elastic element 133 in a compressed state.

[0051] As can be seen, when the elastic element 133 is located behind the sliding direction of the slider 131, by applying force to the first dial 132, the slider 131 can be driven to slide in a direction away from the elastic element 133. The slider 131 can apply a pulling force to the elastic element 133, thereby making the elastic element 133 in a stretched state.

[0052] For example, the elastic element 133 is a spring. Taking the elastic element 133 located in front of the slider 131 in the sliding direction as an example, when no force is applied to the first switch 132, the elastic element 133 is in its natural state. By pressing the slider 131, the elastic element 133 can be compressed; or when no force is applied to the first switch 132, the elastic element 133 is already compressed. By pressing the slider 131, the degree of compression of the elastic element 133 can be increased. Conversely, when the force applied to the first switch 132 is released, the restoring force of the elastic element 133 can be used to apply force to the slider 131, causing the slider 131 to return to its original position.

[0053] In some embodiments, the slider 131 has a first end 1311 and a second end 1312, the first end 1311 being the end closer to the elastic member 133, and the second end 1312 being the end farther from the elastic member 133, and the first knob 132 is fixed at the first end 1311, such as... Figure 6 and Figure 10 As shown. The first knob 132 is fixed at the first end 1311, so that the distance between the first knob 132 and the elastic member 133 is small, which makes it easier to transmit the force applied to the first knob 132 to the elastic member 133, thereby improving the response sensitivity of the elastic member 133.

[0054] In some embodiments, the mounting base 110 is provided with a mounting groove 111, and the slider 131 and the elastic element 133 are installed in the mounting groove 111, such as... Figures 4-6 , Figure 8 As shown. Placing the slider 131 and the elastic element 133 in the mounting groove 111 can enhance the compactness of the clamping mechanism, reduce its size, and improve its aesthetics.

[0055] In some embodiments, a gap 1111 exists between the second end 1312 of the slider 131 and the sidewall of the mounting groove 111, such as... Figure 6 As shown. For example, the arc length of the mounting groove 111 is greater than the sum of the arc length of the slider 131 and the initial length of the elastic member 133, so that when one end of the elastic member 133 abuts against the inner wall of one side of the mounting groove 111, a gap 1111 can be formed between the second end 1312 of the slider 131 and the inner wall of the other side of the mounting groove 111, as shown. Figure 6 As shown. The initial state of the elastic element 133 can be either a natural state or a compressed state. The gap 1111 is a gap with a preset arc length. For example, the arc length is 10~30°.

[0056] The inventors discovered during their research that when the slider 131 and the elastic element 133 are placed into the mounting groove 111, if the arc length of the mounting groove 111 is too small, for example, if the arc length of the mounting groove 111 and the arc length of the slider 131 are the same as the sum of the initial length of the elastic element 133, there may be a risk that the elastic element 133 will be squeezed out of the mounting groove 111, which increases the difficulty of installation.

[0057] In this embodiment, the clamping mechanism has a pre-reserved gap 1111 between the second end 1312 of the slider 131 and the side wall of the mounting groove 111. When the slider 131 and the elastic member 133 are placed into the mounting groove 111, the gap 1111 provides clearance space for the slider 131. After the slider 131 is moved into the gap 1111, the installation space of the elastic member 133 can be increased. The slider 131 does not cause compression on the elastic member 133 or the compression force on the elastic member 133 is very small, making it difficult for the elastic member 133 to fall out during installation. Furthermore, after the slider 131 and the elastic member 133 are placed into the mounting groove 111, the housing 122 is then covered over the clamping assembly and enclosed in the mounting groove 111. Finally, the slider 131 is moved to the mounting position and fixed.

[0058] In some embodiments, the clamp assembly further includes a housing 122 that covers the clamp 121 and is fixedly connected to the slider 131, such as... Figures 1-3 As shown. The housing 122 is also fixedly connected to one end of the clamp 121. The mounting base 110 is provided with a sliding groove 112, and the other end of the clamp 121 is slidably disposed in the sliding groove 112, as shown. Figure 4 , Figure 5 and Figure 8 As shown. Figure 4 , Figure 7 and Figure 9 As shown, one end of the clamp 121 has a first protrusion 1211, which protrudes from the upper surface of the clamp 121. The housing 122 has a fixing hole 1222, and the first protrusion 1211 is installed in the fixing hole 1222, thus fixing one end of the clamp 121 to the housing 122. Figure 4 and Figure 9 As shown, the other end of the clamp 121 has a second protrusion 1212, which protrudes from the lower surface of the clamp 121 and is movably engaged within the slide groove 112. Figure 5 and Figure 8 As shown, the slide 112 is an inclined groove. For example, the distance between the slide 112 and the inner wall of the mounting base 110 gradually increases from one end to the other, thereby forming the slide 112 as an inclined groove.

[0059] For example, when the clamp assembly is initially in a closed state, the clamping mechanism of this embodiment can drive the slider 131 to slide by applying force to the first dial 132. The sliding of the slider 131 can drive the housing 122 to slide. Since the housing 122 is also fixedly connected to one end of the clamp 121, the clamp 121 can be driven to slide by the housing 122. Specifically, the other end of the clamp 121 slides along the slide groove 112, thereby switching the clamp assembly from a closed state to an open state. Conversely, when the force applied to the first dial 132 is released, the slider 131 slides in the opposite direction under the action of the elastic member 133, thereby switching the clamp assembly from an open state to a closed state.

[0060] In some embodiments, the housing 122 and the slider 131 are connected by a fastener 123, such as Figure 6 As shown. For example, the fixing member 123 is a fixing bolt. The fixing member 123 is located at the second end 1312 of the slider 131, and the first toggle button 132 is symmetrically distributed with the fixing member 123 at the first end 1311 and the second end 1312 of the slider 131, as shown. Figure 6 As shown. That is, the distance between the first knob 132 and the first end 1311 is the same as the distance between the fixing member 123 and the second end 1312. The first knob 132 and the fixing member 123 are symmetrically distributed at the first end 1311 and the second end 1312 of the slider 131, which can make the slider 131 uniformly subjected to force.

[0061] like Figure 10 As shown, the second end 1312 of the slider 131 is provided with a second mounting hole 1314, which is used to install the fastener 123.

[0062] In some embodiments, the housing 122 is further provided with a limiting groove 1221, and the drive assembly 130 further includes a second toggle 134, which is located within the limiting groove 1221. The second toggle 134 is also fixedly connected to the mounting base 110, such as... Figures 3-7 As shown. By cooperating with the second dial 134 and the limiting groove 1221, the displacement of the housing 122 in the circumferential direction of the mounting base 110 can be limited, thereby limiting the displacement of the slider 131 in the circumferential direction of the mounting base 110.

[0063] In some embodiments, the structure of the second toggle 134 is the same as that of the first toggle 132. Specifically, the end of the second toggle 134 has a second screw 1341, which is threadedly connected to the mounting base 110, such as... Figure 6 and Figure 7As shown. Exemplarily, the second screw 1341 is integrated into the end of the second dial 134, meaning the second dial 134 and the second screw 1341 are a single unit. Exemplarily, the mounting base 110 has a third mounting hole 113, which has a threaded structure (a common threaded structure in the prior art, not shown in the figure). The surface of the second screw 1341 has a threaded structure matching this threaded structure (not shown in the figure). By screwing the second screw 1341 into the third mounting hole 113, a threaded connection between the second screw 1341 and the third mounting hole 113 can be achieved. Figures 6-8 As shown.

[0064] In this embodiment, the clamping mechanism has a second dial 134 that is threadedly connected to the mounting base 110 via a second screw 1341 at its end. When assembling the second dial 134, the second screw 1341 can be directly installed into the third mounting hole 113 on the mounting base 110, requiring only one step and making the installation process simple. In addition, the second dial 134 can be installed on the mounting base 110 from the outside, and its operating space is not restricted, making it easy to operate.

[0065] In some embodiments, the circumferential surface of the second toggle 134 is curved, such as... Figures 1-7 As shown. Exemplarily, when the first knob 132 is turned, the second knob 134 can serve as a fulcrum, thereby facilitating one-handed operation of the first knob 132. In the clamping mechanism of this embodiment, the second knob 134 is a cylindrical arc surface, which makes the second knob 134 suitable for operation in all directions; moreover, the circumferential surface of the second knob 134 is arc surface, which also makes the shape of the second knob 134 unaffected by the tightness of the second screw 1341, and also has an aesthetic appeal.

[0066] The second aspect of this embodiment describes the optical coupler in detail.

[0067] The optical coupler of this embodiment includes a clamping mechanism. The clamping mechanism is the clamping mechanism of any of the technical solutions in the first aspect of this embodiment.

[0068] The optical coupler of this embodiment also includes an optical mechanism. Exemplarily, the optical mechanism includes a lens barrel 210, optical components mounted within the lens barrel 210, and a knob assembly 220 sleeved outside the lens barrel 210, such as... Figures 1-5 , Figure 6 As shown. Preferably, the mounting base 110 and the lens barrel 210 in the clamping mechanism can be an integral structure, such as... Figure 8 As shown.

[0069] In some embodiments, the mounting base 110 and the lens barrel 210 may also be separate structures. When the mounting base 110 and the lens barrel 210 are separate structures, the mounting base 110 and the lens barrel 210 can be detachably connected by a threaded structure. The structure of the lens barrel 210, the optical components, and the knob assembly 220 can be the same as in the prior art, and will not be described in detail here.

[0070] The optical coupler of this embodiment has a clamping mechanism according to any of the technical solutions in this embodiment, which makes the optical coupler of this embodiment easy to install and easy to operate; at the same time, the optical coupler can also adapt to more contact postures of the fingers.

[0071] The third aspect of this embodiment provides a detailed description of the endoscope system.

[0072] 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.
