Detailed Implementation
[0030] 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.
[0031] 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.
[0032] 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".
[0033] In related optical couplers, a spiral groove is formed on the side wall of the inner sleeve, and multiple lenses are slidably installed within the spiral groove, allowing for lens position adjustment through the sliding of the lenses within the spiral groove. To ensure the sealing of the inner core, an outer sleeve is also provided outside the inner sleeve, with connecting seats at the ends of both the inner and outer sleeves. However, the inventors discovered that this fitting method not only creates potential sealing issues between the ends of the inner and outer sleeves and the connecting seats, but also between the side walls of the inner and outer sleeves, resulting in insufficient sealing performance of the inner core and making it unsuitable for high-pressure, high-temperature sterilization environments.
[0034] This application applies to inner cores for high-temperature sterilization. By forming the optical component into a side-wall sealed structure, when the outer sleeve and the optical component are fitted together, the potential sealing problem between the side wall of the optical component and the outer sleeve can be avoided, thereby helping to improve the sealing performance of the inner core.
[0035] The following is in conjunction with the appendix Figures 1 to 11 The present application provides a detailed description of the inner core, optical coupler, and endoscope system suitable for high-temperature sterilization through specific embodiments and application scenarios.
[0036] The first aspect of this embodiment describes in detail an inner core suitable for high-temperature sterilization.
[0037] This embodiment applies to high-temperature sterilized inner cores and is used for optical couplers. The optical coupler connects the endoscope and camera to enable signal transmission between them. One end of the optical coupler connects to the endoscope's eyepiece cover 400, and the other end connects to the camera. Figure 6 A schematic diagram of the optical coupler engaging with the eyepiece cover 400 is shown. 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 a camera via the optical coupler. The structure of the endoscope may be existing technology and is not shown here.
[0038] This embodiment applies to inner cores subjected to high-temperature sterilization, including optical components 130, such as... Figure 2 As shown. The optical component 130 has at least a sidewall-sealed structure. In this embodiment, the optical component 130 has at least a sidewall-sealed structure, that is, the sidewall of the optical component 130 is an integral structure, or the sidewall of the optical component 130 does not have openings or gaps that penetrate the wall surface, which could easily cause air or liquid leakage.
[0039] In some embodiments, the optical component 130 includes a plurality of optical lenses 131, such as Figure 4 As shown. The optical lens 131 is one or more of a lens, prism, etc. The optical lenses 131 are distributed along the axial direction of the inner core, and at least one of the multiple optical lenses 131 can move along the axial direction of the inner core to adjust the image size and / or sharpness.
[0040] The optical assembly 130 also includes a second sleeve 132, which has a spiral groove 1321. The optical lens 131 is slidably mounted in the spiral groove 1321. Figure 4 As shown. For example, the spiral groove 1321 extends through the wall of the second sleeve 132. By sliding in the spiral groove 1321, the optical lens 131 can move along the axial direction of the inner core, thereby adjusting the image size and / or sharpness.
[0041] The optical assembly 130 also includes a third sleeve 133, which is fitted over the second sleeve 132, thus forming the optical assembly 130 with a sidewall-sealed structure, such as... Figure 4 As shown. For example, the sidewall of the third sleeve 133 is an integral structure. When the third sleeve 133 is sleeved outside the second sleeve 132, the spiral groove 1321 can be blocked, thereby making the optical component 130 form a sidewall sealed structure.
[0042] Not limited to this, the optical assembly 130 may also exclude the third sleeve 133. For example, the spiral groove 1321 is located on the inner wall surface of the second sleeve 132, and the depth of the spiral groove 1321 is less than the wall thickness of the second sleeve 132, thereby enabling the optical assembly 130 to be formed as a sidewall-sealed structure.
[0043] This embodiment is applicable to inner cores subjected to high-temperature sterilization, and also includes a first sleeve 110 and a connecting seat 120, such as... Figure 1 , Figure 2 and Figure 4 As shown. The first sleeve 110 has an internally hollow structure, and the optical component 130 is installed inside the first sleeve 110. The connecting seat 120 is located at the ends of the first sleeve 110 and the optical component 130, and maintains a sealed connection between the connecting seat 120 and the first sleeve 110 and the optical component 130. In some embodiments, the first sleeve 110 also has a side-wall sealed structure, and the connecting seat 120 is an integral structure, thereby minimizing the connection gaps in the inner core. Figure 1 A schematic diagram of the overall structure of the inner core is shown.
[0044] This embodiment is applicable to the inner core for high-temperature sterilization. Since the optical component 130 has at least a sealed sidewall, when the first sleeve 110 is engaged with the optical component 130, the sealing risk between the sidewall of the optical component 130 and the first sleeve 110 can be avoided. The inner core structure of this embodiment can reduce the sealing risk between the optical component 130 and the first sleeve 110 and the connecting seat 120, thereby helping to improve the sealing performance of the inner core, so that the inner core of this embodiment can meet the requirements of high-temperature sterilization.
[0045] In some embodiments, when the optical component 130 is installed inside the first sleeve 110, the first sleeve 110 and the third sleeve 133 are misaligned at the end that mates with the connecting seat 120, such as... Figure 2 and Figure 3 As shown. For example, at one end that mates with the connecting seat 120, the first sleeve 110 protrudes beyond the end of the third sleeve 133. For example, at one end that mates with the connecting seat 120, the third sleeve 133 protrudes beyond the end of the first sleeve 110, as shown. Figure 2 and Figure 3 As shown.
[0046] This embodiment is applicable to the inner core that is sterilized at high temperature. At the end that mates with the connecting seat 120, the first sleeve 110 and the third sleeve 133 are misaligned, so that a bent sealing path is formed between the end of the connecting seat 120 and the end of the first sleeve 110 and the end of the optical component 130, thereby improving the sealing performance between the end of the connecting seat 120 and the end of the first sleeve 110 and the end of the optical component 130, so as to further improve the sealing performance of the inner core.
[0047] In some embodiments, when the connecting seat 120 is located at the end of the first sleeve 110 and the optical component 130, the connecting seat 120 is sealed to the first sleeve 110 and the third sleeve 133 through one or more of the following methods: bonding, abutment, interference fit, and sealing ring fit. The portion of the connecting seat 120 that contacts the first sleeve 110 and the third sleeve 133 is sealed through one or more of the following methods: bonding, abutment, interference fit, and sealing ring fit. This enhances the stability and sealing of the connection between the connecting seat 120 and the first sleeve 110 and the third sleeve 133.
[0048] In some embodiments, a connecting component is further provided between the optical component 130 and the connector 120. Connecting the optical component 130 and the connector 120 via the connecting component further enhances the stability of the connection between them. For example, the connecting component is located inside the inner core, that is, on the surfaces of the optical component 130 and the connector 120 facing each other, thus ensuring that the connecting component does not affect the sealing performance of the inner core.
[0049] In some embodiments, the connection assembly includes a connecting pin 141 and a mounting hole 142, such as Figure 2 and Figure 5 As shown. A connecting pin 141 is located on one of the optical assembly 130 and the connector 120, and a mounting hole 142 is located on the other of the optical assembly 130 and the connector 120, and the mounting hole 142 is used to mount the connecting pin 141. Exemplarily, the connecting pin 141 or the mounting hole 142 may be located on the second sleeve 132 of the optical assembly 130 or on the third sleeve 133 of the optical assembly 130. Figure 2 and Figure 5 The diagrams show the connecting pin 141 located on the third sleeve 133 and the mounting hole 142 located on the connecting seat 120.
[0050] In some embodiments, when the connecting pin 141 is located on the connecting seat 120, the depth to which the connecting pin 141 is inserted into the connecting seat 120 is less than the wall thickness of the connecting seat 120. This allows the connecting pin 141 to be located inside the inner core, preventing the opening in the connecting seat 120 from being created due to the installation of the connecting pin 141, thus ensuring that the connecting pin 141 does not affect the sealing performance of the inner core. Similarly, when the mounting hole 142 is located on the connecting seat 120, the depth of the mounting hole 142 is less than the wall thickness of the connecting seat 120. That is, the mounting hole 142 is located on the inner surface of the connecting seat 120, and the mounting hole 142 does not penetrate the wall of the connecting seat 120, thus ensuring that the mounting hole 142 does not affect the sealing performance of the inner core.
[0051] In some embodiments, the outer wall of the first sleeve 110 is provided with a first protruding edge 111, and the outer wall of the connecting seat 120 is provided with a second protruding edge 121, such as... Figure 2 and Figure 3 As shown. The first protruding edge 111 can also be called the first folded edge, and the second protruding edge 121 can also be called the second folded edge. When the connecting seat 120 is located at the end of the first sleeve 110 and the optical component 130, the side wall of the connecting seat 120 is in contact with the outer wall of the first sleeve 110 and the optical component 130, and the first protruding edge 111 and the second protruding edge 121 abut against each other, as shown. Figure 2 and Figure 3 As shown. The side wall of the connecting seat 120 is in contact with the outer wall of the first sleeve 110 and the optical component 130. This can be achieved by the side wall of the connecting seat 120 directly contacting and abutting against the outer wall of the first sleeve 110 and the optical component 130, or by using an intermediate connector to achieve the contact between the side wall of the connecting seat 120 and the outer wall of the first sleeve 110 and the optical component 130.
[0052] This embodiment is applicable to the inner core that is sterilized at high temperature. The side wall of the connecting seat 120 is in contact with the outer wall of the first sleeve 110 and the optical component 130, and the first protruding edge 111 and the second protruding edge 121 abut against each other. Through the abutment of the first protruding edge 111 and the second protruding edge 121, a bent sealing path is formed between the connecting seat 120 and the first sleeve 110 and the optical component 130, thereby improving the sealing performance between the connecting seat 120 and the first sleeve 110 and the optical component 130, so as to further improve the sealing performance of the inner core.
[0053] On the other hand, this embodiment is applicable to inner cores that are sterilized at high temperatures. By abutting the first protruding edge 111 and the second protruding edge 121, the contact area between the connecting seat 120 and the first sleeve 110 can be increased. When the connecting seat 120 and the first sleeve 110 are pre-tightly fitted together, the sealing performance between the connecting seat 120 and the first sleeve 110 can be further improved.
[0054] Thirdly, this embodiment is applicable to the inner core of high-temperature sterilization. When the first protruding edge 111 and the second protruding edge 121 abut against each other, the first protruding edge 111 and the second protruding edge 121 can produce slight elastic deformation, thereby making the first protruding edge 111 and the second protruding edge 121 fit more tightly, and also improving the sealing performance between the connecting seat 120 and the first sleeve 110.
[0055] In some embodiments, the first sleeve 110 and / or the connecting seat 120 are provided with a groove 122 for installing the seal 500, such as... Figure 3 As shown. When the inner core is fitted with the adjustment assembly, the sealing between the inner core and the adjustment assembly can be enhanced by the seal 500 provided in the groove 122, thereby further improving the sealing performance of the optical coupler.
[0056] The second aspect of this embodiment describes the optical coupler in detail.
[0057] The optical coupler in this embodiment includes an inner core 100, such as... Figure 8 As shown. The inner core is an inner core suitable for high-temperature sterilization according to any of the technical solutions in the first aspect of this embodiment.
[0058] The optical coupler of this embodiment also includes an adjustment component. The adjustment component is rotatably mounted on the inner core 100 and is used to adjust the position of the optical lens 131 in the inner core 100 along the axial direction of the inner core, thereby adjusting the image size and / or sharpness. For example, the number of adjustment components may be one or two.
[0059] For example, the adjustment assembly includes an adjustment ring 210, a first magnetic drive module 220, and a second magnetic drive module 230, such as... Figure 2 , Figures 5-9 As shown. The first magnetic drive module 220 is sleeved on the third sleeve 133, and the second magnetic drive module 230 is sleeved on the first sleeve 110, as follows. Figure 2 and Figure 9 As shown. The principle of adjusting the optical lens 131 by means of magnetic drive is the same as that of the prior art, and will not be described in detail here.
[0060] The optical coupler in this embodiment also includes a clamp assembly 300, such as Figures 5-9 As shown. The clamp assembly 300 is fixedly connected to the end of the inner core 100. The clamp assembly 300 is used to engage the eyepiece cover 400 of the endoscope to couple the endoscope and the camera, as shown. Figure 1 As shown.
[0061] like Figure 8 As shown, the adjustment assembly is also sealed to the inner core 100 and the clamp assembly 300 via a seal 500, which further enhances the sealing performance of the optical coupler.
[0062] For example, the clamp assembly 300 includes a plurality of openable and closable clamps 310, such as Figure 10 and Figure 11 As shown. By opening the clamps 310, the eyepiece cover 400 can be installed within the space formed by the multiple clamps 310, and then closing the clamps 310 can fix the eyepiece cover 400; or by opening the clamps 310, the eyepiece cover 400 can be removed from the clamp assembly 300. The specific structure of the clamps 310 is existing technology and will not be described in detail here.
[0063] The optical coupler of this embodiment has an inner core suitable for high-temperature sterilization according to any of the technical solutions in the first aspect of this embodiment, which improves the sealing performance of the optical coupler and makes it suitable for high-temperature sterilization.
[0064] The third aspect of this embodiment provides a detailed description of the endoscope system.
[0065] 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 400 of the endoscope, thereby coupling the endoscope to the camera.
[0066] The endoscope system of this embodiment has an optical coupler according to any of the technical solutions in the second aspect of this embodiment, which improves the sealing performance of the endoscope system and makes it suitable for high-temperature sterilization.
