Description

Plug-in assembly and endoscope system Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a plug-in assembly and an endoscope system. Background Art

[0002] Endoscopes are commonly used medical devices that allow direct access to the body's natural cavities and are increasingly used in diagnostic examinations, minimally invasive surgery, and other areas. Endoscopes typically consist of an insertion portion for insertion into the human body, a handle for controlling operations, and a host device for analyzing and / or displaying the internal environment of the body's natural cavities. These three components work together to allow for internal visualization, lesion detection, and treatment.

[0003] In some cases where coordinated operations are required or spare handles need to be prepared, two or more endoscope handles may need to be connected to the host to ensure smooth and safe operation. For this purpose, the host usually has multiple interfaces for the handles to be plugged in. Since different types of endoscopes have different first terminal modules in their handle connectors, in order to adapt to different endoscopes, the second terminal modules in the multiple interfaces of the host are also different. In the related art, when different models of endoscopes are plugged into the host, the interfaces are difficult to identify, and the handle connectors need to be tried one by one with the host interface, which results in low plug-in efficiency.

DETAILED DESCRIPTION

[0032] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be described in detail below. Obviously, the embodiments described are only some of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other implementation methods obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0033] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0034] In each embodiment of the present application, "proximal end" and "distal end" refer to the position of each component relative to the user in the use environment, wherein the end closer to the user is designated as the "proximal end" and the end farther from the user is designated as the "distal end".

[0035] In the related art, the main unit usually has multiple interfaces for the handle to be plugged in. Different types of endoscopes have different first terminal modules in the handle connectors. In order to adapt to different endoscopes, the second terminal modules in the multiple interfaces of the main unit are also different. Because the second terminal modules are located inside the main unit housing and the interfaces have the same appearance, it is difficult for the operator to directly observe whether each interface is compatible with the handle connector by looking at the interface appearance during plugging. The operator can only try to match the handle connector with the main unit interface one by one. On the other hand, during the plugging process, the connector needs to be rotated to achieve circumferential positioning of the connector and the interface, which is cumbersome, increases the operator's workload, and reduces the plugging efficiency.

[0036] To this end, the present application provides a plug-in assembly, which provides an identification part on the shell of the connector and the interface, and can identify different models of connectors and interfaces based on the identification part, thereby improving the plug-in efficiency; further, the identification part can also realize the alignment of the connector and the interface in the circumferential direction, which not only further improves the plug-in efficiency of the connector and the interface, but also compared with setting two groups of identification parts to respectively realize the matching identification of the connector and the interface and the circumferential alignment identification of the connector and the interface, the present application can realize two functions through one group of identification parts, and also helps to simplify the structure of the plug-in assembly.

[0037] The following describes in detail the plug-in assembly and endoscope system provided in the embodiments of the present application through specific embodiments and their application scenarios with reference to Figures 1 to 9.

[0038] The first aspect of this embodiment provides a detailed description of the plug-in assembly.

[0039] The plug assembly of this embodiment is applied to an endoscope system, specifically, to connect an endoscope handle to an all-in-one device 300. The plug assembly of this embodiment is particularly suitable for situations where multiple endoscope handles need to be plugged into the all-in-one device 300.

[0040] The plug-in assembly of this embodiment includes a connector 110 and an interface 120, as shown in Figures 1 to 6. The connector 110 is located on the distal end of the handle's adapter cable 210 or on the housing 310 of the all-in-one device 300, and the interface 120 is located on the other of the adapter cable 210 and the housing 310. By plugging the connector 110 and the interface 120 together, the endoscope handle and the all-in-one device can be connected, thereby enabling data transmission. Figures 1, 5, and 6 show schematic diagrams of the connector 110 being located on the distal end of the handle's adapter cable 210, and Figures 1 to 3 show schematic diagrams of the interface 120 being located on the housing 310 of the all-in-one device 300.

[0041] The connector 110 includes a first housing 111 and a first terminal module 112. The first housing 111 protects the first terminal module 112, as shown in Figures 5 and 6. The connector 110 is available in at least two models, each with a different first terminal module 112. This means that the plug assembly has connectors 110 with at least two different first terminal modules 112. Each model of connector 110 can have one, two, or more. Figures 1 and 5 illustrate a schematic diagram of a connector 110 with two of each model.

[0042] The interface 120 includes a second housing 121 and a second terminal module 122. The second housing 121 protects the second terminal module 122, as shown in Figure 4. The interface 120 is available in at least two models, each with a different second terminal module 122. This means that the plug assembly has at least two different types of interfaces 120 with different second terminal modules 122. Each model of interface 120 can have one, two, or more. Figures 1 to 4 illustrate a model with two interfaces 120.

[0043] Preferably, at least two types of connectors 110 have at least two types of first identification portions 110a, which are disposed on the first housing 111, as shown in Figures 1 and 5. That is, each connector 110 has a first identification portion 110a disposed on the first housing 111, and connectors 110 with different first terminal modules 112 have different first identification portions 110a, as shown in Figures 1 and 5. Specifically, connectors 110 with two types of first terminal modules 112 have two corresponding types of first identification portions 110a; connectors 110 with three types of first terminal modules 112 have three corresponding types of first identification portions 110a.

[0044] Preferably, at least two types of interfaces 120 have at least two types of second identification portions 120a, which are disposed on the housing 310, as shown in Figures 1 to 4. That is, each interface 120 corresponds to a second identification portion 120a, and interfaces 120 with different second terminal modules 122 have different second identification portions 120a, as shown in Figures 1 to 4. Specifically, an interface 120 with two types of second terminal modules 122 has two corresponding types of second identification portions 120a; an interface 120 with three types of second terminal modules 122 has three corresponding types of second identification portions 120a.

[0045] More preferably, the type of the second identification portion 120a matches that of the first identification portion 110a, which facilitates quick identification of the second identification portion 120a that matches the first identification portion 110a, thereby quickly identifying the interface 120 that matches the connector 110. For example, when the first identification portion 110a is a graphic, the second identification portion 120a is also a graphic, as shown in Figures 1 to 5; when the first identification portion 110a is a number, the second identification portion 120a is also a number, as shown in Figures 7 to 9.

[0046] According to an optional embodiment, the first identification portion 110a and the second identification portion 120a are at least two types of the graphics. For example, as shown in Figures 1 to 5, the first identification portion 110a includes two types: an arrow and a triangle. Correspondingly, the second identification portion 120a also includes two types: an arrow and a triangle. The connector 110 with an arrow identification can be mated with the interface 120 with an arrow identification, and the connector 110 with a triangle identification can be mated with the interface 120 with a triangle identification.

[0047] According to another optional embodiment, the first identification portion 110a and the second identification portion 120a are at least two types of numbers. For example, as shown in Figures 7 to 9, the first identification portion 110a includes three types of numbers "1", "2", and "3". Correspondingly, the second identification portion 120a also includes three types of numbers "1", "2", and "3". The connector 110 with the number "1" identification can be matched and plugged with the interface 120 with the number "1", the connector 110 with the number "2" identification can be matched and plugged with the interface 120 with the number "2", and the connector 110 with the number "3" identification can be matched and plugged with the interface 120 with the number "3".

[0048] According to another optional embodiment, the first identification portion 110a and the second identification portion 120a are at least two types of graphics and numbers. For example, the first identification portion 110a includes two types of arrows and the number "1". Correspondingly, the second identification portion 120a also includes two types of arrows and the number "1". The connector 110 with the arrow mark can be mated with the interface 120 with the arrow mark, and the connector 110 with the number "1" can be mated with the interface 120 with the number "1".

[0049] In the plug-in assembly of this embodiment, when the connector 110 and the interface 120 are plugged into each other and circumferentially aligned, the first identification portion 110a is located at a position aligned with the second identification portion 120a, so that based on the matching and alignment of the first identification portion 110a and the second identification portion 120a, the connector 110 and the interface 120 can be plugged into each other and circumferentially aligned, as shown in Figure 1 or Figure 7.

[0050] That is, the first identification portion 110a and the second identification portion 120a of this embodiment have at least the following two functions: one is to determine whether the connector 110 can be plugged into the interface 120 by matching the first identification portion 110a with the second identification portion 120a (such as arrows matching arrows, triangles matching triangles); the second is that when the first identification portion 110a on the connector 110 matches the second identification portion 120a on the interface 120, it is also possible to determine whether the connector 110 and the interface 120 are aligned in the circumferential direction by whether the first identification portion 110a on the connector 110 and the second identification portion 120a on the interface 120 are aligned.

[0051] The plug-in assembly of this embodiment can identify different types of connectors 110 and interfaces 120 through the first identification portion 110a and the second identification portion 120a, and can also achieve circumferential alignment of the connector 110 and the interface 120 through the first identification portion 110a and the second identification portion 120a.

[0052] Since the first identification portion 110a and the second identification portion 120a are respectively arranged on the first shell 111 and the second shell 121, they have the advantage of being easy to identify, which can improve the plug-in efficiency and solve the technical problem of the endoscope system in the related art that the connector 110 and the interface 120 are difficult to identify.

[0053] On the other hand, in the plug-in assembly of this embodiment, the first identification portion 110a and the second identification portion 120a not only realize the identification of different types of connectors 110 and interfaces 120, but also have the function of realizing the alignment of the connector 110 and the interface 120 in the circumferential direction. Not only can the connector 110 and the interface 120 be quickly plugged in, but also compared to setting two groups of identification portions to respectively realize the matching identification of the connector 110 and the interface 120 and the circumferential alignment identification of the connector 110 and the interface 120, the present application can realize two functions through one group of identification portions, and also helps to simplify the structure of the plug-in assembly.

[0054] According to an optional embodiment, the first identification portion 110a and the first housing 111 are integrally formed, that is, the first identification portion 110a and the first housing 111 are integrally molded, thereby simplifying the production process of the connector 110. Without limitation, the first identification portion 110a can also be fixed to the surface of the first housing 111. For example, the first identification portion 110a can be fixed to the surface of the first housing 111 by gluing, printing, or other methods.

[0055] According to an optional embodiment, the second identification portion 120a and the second housing 121 are integrally formed, that is, the second identification portion 120a and the second housing 121 are integrally molded, thereby simplifying the production process of the interface 120. Without limitation, the second identification portion 120a can also be fixed to the surface of the second housing 121. For example, the second identification portion 120a can be fixed to the surface of the second housing 121 by gluing, printing, or other methods.

[0056] According to an optional embodiment, the connector 110 further includes a first positioning portion 113, which is disposed on the first housing 111, as shown in FIG5 . Specifically, the first positioning portion 113 is located on the portion of the first housing 111 that plugs into the interface 120. The interface 120 further includes a second positioning portion 123, which is disposed on the inner wall of the second housing 121, as shown in FIG4 . Specifically, the second positioning portion 123 is located on the portion of the second housing 121 that plugs into the connector 110.

[0057] Preferably, the first positioning portion 113 is a projection or a groove, and the second positioning portion 123 is the other of the projection or the groove, and the shape of the projection matches the shape of the groove. FIG5 shows a schematic diagram of the first positioning portion 113 being a projection, and FIG4 shows a schematic diagram of the second positioning portion 123 being a groove. More preferably, the first positioning portion 113 extends along the axial direction of the connector 110, and the second positioning portion 123 extends along the axial direction of the interface 120, thereby enhancing the stability of the circumferential positioning of the connector 110 and the interface 120. Exemplarily, both the projection and the groove are elongated square structures, and the projection can be snapped into the groove, as shown in FIG4 and FIG5.

[0058] The plug-in assembly of the preferred technical solution of this embodiment can fix the connector 110 and the interface 120 in the circumferential direction through the snap connection between the first positioning portion 113 and the second positioning portion 123, thereby achieving preliminary fixation of the connector 110 and the interface 120.

[0059] Preferably, the number of first positioning portions 113 is at least two, and at least two first positioning portions 113 are distributed along the circumferential direction of the first shell 111; the number of second positioning portions 123 is at least two, and at least two second positioning portions 123 are distributed along the circumferential direction of the second shell 121, thereby ensuring the reliability of the circumferential positioning of the existing joint 110 and the interface 120.

[0060] According to an optional embodiment, the first identification portion 110a is provided on the upper surface of the first housing 111, and the central axis of the first identification portion 110a is aligned with the central axis of the first positioning portion 113, as shown in Figure 5. Specifically, after the connector 110 and the interface 120 are plugged into and mated, the first identification portion 110a is located in the upper portion of the first housing 111. At the same time, when the first identification portion 110a and the first positioning portion 113 are in the same plane, the central axes thereof coincide with each other. When the first identification portion 110a and the first positioning portion 113 are in different planes, the central axes thereof are parallel to each other and coincide with each other in the vertical direction, as shown in Figure 5.

[0061] Similarly, the second identification portion 120a is provided on the upper surface of the housing 310, and the central axis of the second identification portion 120a is aligned with the central axis of the second positioning portion 123, as shown in Figure 4. Specifically, the central axis of the second identification portion 120a is parallel to the central axis of the second positioning portion 123, and the two coincide with each other in the vertical direction, as shown in Figure 4.

[0062] Without limitation, the second identification portion 120 a may also be provided on the front side of the housing 310 (the side where the interface 120 is provided), in which case the central axis of the second identification portion 120 a and the central axis of the second positioning portion 123 are perpendicular to each other.

[0063] The plug assembly of the preferred technical solution of this embodiment aligns the central axis of the first identification portion 110a with the central axis of the first positioning portion 113, and the central axis of the second identification portion 120a with the central axis of the second positioning portion 123. When the operator plugs the connector 110 into the interface 120, the alignment of the first identification portion 110a with the second identification portion 120a ensures that the first positioning portion 113 is aligned with the second positioning portion 123, thereby achieving circumferential positioning of the connector 110 and the interface 120. This alignment method has the advantage of being easy to identify because the first identification portion 110a and the second identification portion 120a are located outside the first shell 111 and the second shell 121, respectively. It also reduces the number of rotational alignment steps when plugging the connector 110 and the interface 120, further improving the plugging efficiency of the two.

[0064] According to an optional embodiment, the connector 110 also includes a first fixing portion 114, which is arranged on the first shell 111, and the interface 120 also includes a second fixing portion 124, which is arranged on the inner wall of the second shell 121, and based on the clamping connection between the first fixing portion 114 and the second fixing portion 124, the connector 110 is fixedly connected to the interface 120, as shown in Figures 4 and 5.

[0065] 4 and 5 only illustrate schematic diagrams in which one connector 110 is provided with the first fixing portion 114 and one interface 120 is provided with the second fixing portion 124. It is understood that corresponding first fixing portions 114 may also be provided on the remaining two connectors 110, and corresponding second fixing portions 124 may also be provided on the remaining two interfaces 120.

[0066] Illustratively, the first fixing portion 114 is one of a slot and a buckle, and the second fixing portion 124 is the other of the slot and the buckle, and the buckle can be snapped into the slot. FIG5 shows a schematic diagram of a buckle provided on the connector 110, and FIG4 shows a schematic diagram of a slot provided on the interface 120.

[0067] In the plug-in assembly of the preferred technical solution of this embodiment, the clamping connection between the first fixing portion 114 and the second fixing portion 124 can not only further achieve the circumferential limitation of the connector 110 and the interface 120, but also achieve the axial limitation of the connector 110 and the interface 120, thereby fixing the connector 110 in the interface 120.

[0068] According to an optional embodiment, the connector 110 further includes an anti-slip portion 115, which is provided on the first housing 111, as shown in FIG5 . Exemplarily, the anti-slip portion 115 is a convex strip disposed along the circumference of the first housing 111, as shown in FIG5 . When the connector 110 is plugged into the interface 120, the operator can grip the anti-slip portion 115 to facilitate application of force.

[0069] The second aspect of this embodiment describes the endoscope system in detail.

[0070] The endoscope system of this embodiment includes an endoscope assembly and an all-in-one device 300. The endoscope assembly and the all-in-one device 300 are connected via a plug-in assembly, which can be any of the plug-in assembly described in any of the technical solutions of this embodiment. The endoscope assembly includes an endoscope handle and an insert (the structures of the endoscope handle and insert are not shown in the figure and can be existing structures). The all-in-one device 300 includes a housing 310 and a circuit board located within the housing 310. The remaining structures of the endoscope assembly and the all-in-one device 300 are similar to those of the prior art and will not be further described here.

[0071] The endoscope system of this embodiment has a plug-in component of any one of the technical solutions in this embodiment. When multiple endoscope components need to be connected to the all-in-one device 300, it is easy to identify the interface corresponding to the endoscope connector, which can realize quick plug-in of the connector and the interface and simplify the structure of the plug-in component.

[0072] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.
