Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a button assembly, a handle, and an endoscope. Background Technology

[0002] An endoscope is a commonly used medical device that can directly enter human cavities for examination, providing doctors with comprehensive diagnostic information. An endoscope typically includes: an insertion part for insertion into the body, a handle for controlling the bending of the insertion part's tip, and a display device for showing the internal environment of the body's natural cavities. Through the coordination of these three parts, an endoscope can achieve visualization of the human body's interior, exploration of lesions, and treatment.

[0003] Endoscope handles are typically equipped with buttons to send commands to the endoscope's camera module or light source by pressing the button. In related technologies, there are two methods for installing buttons: (1) clamping the button between two housings by fitting the housings together. This assembly method requires constructing a support structure inside the housing for mounting the tactile switch and circuit board, which not only increases the housing processing cost but also makes the button assembly process cumbersome. (2) setting mounting holes on the housing and fixing the button in the mounting holes with screws or other fasteners. The prior art with publication number CN221555518U provides a button structure in which the button consists of a button base and a button cap, with screws connecting the PCB board, housing, and button base. This structure not only results in a complex button structure but also presents a cumbersome assembly process. Utility Model Content

[0004] This utility model discloses a button assembly, a handle, and an endoscope to solve the technical problems of complex button structure and cumbersome assembly process in related technologies.

[0005] To solve the above problems, the present invention adopts the following technical solution: The present invention discloses a button assembly for use in an endoscope. The button assembly includes a button, the button including a button body and a limiting part. The limiting part is located at the distal end of the button body and extends radially outward along the button body. The endoscope housing is provided with a first mounting hole, the button body passing through the first mounting hole, and the limiting part overlapping and limiting the button with the distal end face of the first mounting hole or the inner wall of the housing.

[0006] The handle of this utility model includes a housing and a button assembly, wherein the button assembly is the button assembly described in any one of this utility model; the housing also has a first mounting hole for mounting the button of the button assembly, and an accommodating space is formed inside the housing for accommodating the button assembly.

[0007] The endoscope of this utility model includes a handle and an insertion part, wherein the handle is the handle described in any of the technical solutions of this utility model, and the handle is connected to the insertion part.

[0008] The technical solution adopted in this utility model can achieve the following beneficial effects: This utility model discloses a button assembly. The button includes a button body and a limiting part. When the button is installed in a first mounting hole, the button body passes through the first mounting hole, and the limiting part overlaps with the distal end face of the first mounting hole or the inner wall of the housing. This overlap between the limiting part and the distal end face of the first mounting hole or the inner wall of the housing limits the button body, preventing it from falling out of the first mounting hole, thus achieving initial installation and positioning of the button. Compared to existing button assemblies, this utility model's button assembly not only has a simple button structure but also a simple assembly process. Only one step is needed to achieve the anti-detachment installation of the button on the housing, solving the technical problems of complex button structures and cumbersome assembly procedures in related technologies.

Detailed Implementation

[0012] 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.

[0013] 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.

[0014] 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".

[0015] The button in the related technology includes a button base and a button cap. The button cap is mounted on top of the button base, and screws are used to connect the three components: the PCB board, the housing, and the button base. To secure the button base, it is typically made of a rigid material; to enable the pressing function, the button cap is typically made of a soft material. Button assembly requires not only installing the button base onto the housing but also attaching the button cap to the top of the button base, resulting in a complex button structure and cumbersome assembly process.

[0016] Therefore, this application provides a button assembly. The button assembly includes a button body and a limiting part. After the button body is installed in a first mounting hole on the housing, the limiting part overlaps with the distal end face of the first mounting hole or the inner wall of the housing. This overlap between the limiting part and the distal end face of the first mounting hole or the inner wall of the housing limits the button's position, preventing it from falling out of the first mounting hole. In other words, the button assembly of this application not only has a simple button structure but also a simple assembly process, requiring only one step to achieve the anti-detachment installation of the button on the housing.

[0017] The following is in conjunction with the appendix Figures 1 to 10 The button assembly, handle, and endoscope provided in this application will be described in detail through specific embodiments and application scenarios.

[0018] The button assembly of this embodiment is used in an endoscope, particularly in an endoscope handle. The endoscope handle includes a housing 210, within which a receiving space 213 is formed. The receiving space 213 is used to accommodate structures such as traction wheels, traction ropes, and instrument tubes. Figure 1 and Figure 2 As shown. Not limited to this, the housing 210 also includes a button assembly, a suction valve, a lever, and other structures.

[0019] The button component in this embodiment includes a button 110, such as... Figure 1 Button 110 is a pressure-receiving component. By applying force to button 110, a switch can be triggered to send a command to the endoscope's camera module or light source, etc. Preferably, button 110 includes a button body 111 and a limiting part 112, such as... Figure 8 and Figure 9 As shown. The button body 111 is the main force-bearing component, and the limiting part 112 is used to limit the button and prevent the button 110 from falling off. For example, the button body 111 and the limiting part 112 are an integral structure, as shown... Figure 8 and Figure 9 As shown. When assembling button 110, it is not necessary to assemble button body 111 and limit part 112.

[0020] In some embodiments, the limiting portion 112 is located at the distal end of the button body 111, and the limiting portion 112 extends radially outward along the button body 111, such as... Figure 8 and Figure 9 As shown. Figure 8 As shown, the limiting part 112 forms an outwardly flanged structure at the distal end of the button body 111. The endoscope housing 210 is provided with a first mounting hole 211, such as... Figures 2-4 As shown. For example, the first mounting hole 211 penetrates the housing 210, as... Figures 2-4As shown. For example, the distal end face of the first mounting hole 211 is flush with the inner surface of the housing 210. For example, the distal end face of the first mounting hole 211 protrudes from the inner surface of the housing 210, as shown. Figures 2-4 As shown.

[0021] For example, when the distal end face of the first mounting hole 211 protrudes from the inner surface of the housing 210, the button body 111 passes through the first mounting hole 211, and the limiting part 112 overlaps and limits the movement with the distal end face of the first mounting hole 211, such as... Figures 5-6 As shown. For example, when the distal end face of the first mounting hole 211 is flush with the inner surface of the housing 210, the button body 111 passes through the first mounting hole 211, and at this time the limiting part 112 can also overlap and limit the movement with the inner wall of the housing 210.

[0022] In this embodiment, the button assembly uses the overlap between the limiting part 112 and the distal end face of the first mounting hole 211 or the inner wall of the housing 210 to limit the button body 111, preventing the button body 111 from falling out of the first mounting hole 211, thereby achieving initial installation and positioning of the button 110. Specifically, in the radial direction of the housing 210, the limiting part 112 is used to limit the button body 111.

[0023] The button assembly of this embodiment not only has a simple button 110 structure, but also a simple assembly step. The button 110 can be installed on the housing 210 in one step to prevent it from falling off, which solves the technical problems of complex button 110 structure and cumbersome assembly process in related technologies.

[0024] In this embodiment of the button assembly, the distal end of the button 110 is further provided with a switch portion 120, such as... Figure 7 As shown. The switch unit 120 is used to send commands to the endoscope's camera module or light source, etc. When the button body 111 is subjected to force and moves radially along the housing 210, the button body 111 can abut against the switch unit 120. The abutment of the button body 111 against the switch unit 120 can trigger the switch unit 120 to send commands to the endoscope's camera module or light source, etc.

[0025] In this embodiment, the button assembly has a switch part 120 at the far end of the button 110. This not only allows the button body 111 to contact the switch part 120 by applying force to the button body 111, but also allows the switch part 120 to further limit the button 110 from being dislodged.

[0026] In some embodiments, the switching unit 120 includes a switch 121 and a circuit board 122, such as Figure 10As shown. Switch 121 is fixed to circuit board 122. For example, switch 121 is a tactile switch, and circuit board 122 is a PCB board. Switch 121 can be soldered or glued to circuit board 122. Preferably, when button body 111 is subjected to force and moves radially along housing 210, button body 111 can abut against switch 121, thereby triggering switch 121 to send a command to the endoscope's camera module or light source, etc. Preferably, when switch part 120 is located at the distal end of button 110, circuit board 122 abuts against limiting part 112, such as... Figure 7 As shown. This allows the limiting part 112 to be clamped between the housing 210 and the circuit board 122, thereby further limiting the button 110 by the circuit board 122 and preventing the button 110 from falling out of the first mounting hole 211.

[0027] In some embodiments, the button body 111 is provided with a receiving groove 1111, such as Figure 6 and Figure 9 As shown. When the switch part 120 is located at the distal end of the button 110, the switch 121 is located within the receiving groove 1111. The switch 121 being located within the receiving groove 1111 not only allows the button body 111 to abut against the switch 121 when the button body 111 is moved by force, but also helps to reduce the size of the button assembly and avoid the switch 121 occupying a large space within the housing 210.

[0028] In some embodiments, the housing 210 is provided with a second mounting hole 212, and the circuit board 122 is provided with a third mounting hole 1221. The circuit board 122 is fixedly connected to the housing 210 by fasteners 130 installed in the second mounting hole 212 and the third mounting hole 1221, such as... Figure 2 , Figures 5-7 , Figure 10 As shown. For example, the fastener 130 is a screw. By the locking action of the fastener 130, the circuit board 122 can be fixedly connected to the housing 210, thereby enabling the button 110 and the switch part 120 to be installed and fixed.

[0029] In some embodiments, the limiting portion 112 has at least one second mounting hole 212 at each end, and correspondingly, the circuit board 122 has at least one third mounting hole 1221 at each end, such as... Figures 5-7 , Figure 10 As shown. This enhances the stability of the connection between the circuit board 122 and the housing 210.

[0030] like Figure 6 As shown, the limiting part 112 is located between the two second mounting holes 212. In the axial direction of the housing 210, the limiting part 112 is limited by the second mounting holes 212. For example, the limiting part 112 has a notch 1122 on the side contacting the second mounting hole 212. The notch 1122 engages with the sidewall of the second mounting hole 212 for limiting cooperation, such as... Figure 6 , Figure 8 and Figure 9 As shown.

[0031] In some embodiments, the two sides of the limiting part 112 are in contact with the inner wall of the housing 210, and the limiting part 112 is limited by the housing 210 in the width direction of the housing 210.

[0032] like Figure 6 As shown, in this embodiment, after the button 110 is installed in the first mounting hole 211, the button body 111 can be limited not only by the overlap between the limiting part 112 and the inner wall of the housing 210, but also by the second mounting hole 212 in the axial direction of the housing 210 and by the housing 210 in the width direction. Thus, after the button 110 is installed in the first mounting hole 211, multiple limiting and positioning of the button 110 can be achieved in just one step.

[0033] In some embodiments, the limiting portion 112 is provided with one of a fourth mounting hole 1121 and a protrusion 2111, and the other of the fourth mounting hole 1121 and the protrusion 2111 is provided on the distal surface of the first mounting hole 211. When the button body 111 is mounted in the first mounting hole 211, the protrusion 2111 is inserted into the fourth mounting hole 1121. Figure 8 and Figure 9 As shown, the limiting part 112 is provided with a fourth mounting hole 1121; as Figure 2 and Figure 3 As shown, a protrusion 2111 is provided on the distal surface of the first mounting hole 211. When the button body 111 is installed in the first mounting hole 211, the protrusion 2111 is inserted into the fourth mounting hole 1121. However, the protrusion 2111 may also be provided on the inner wall of the housing 210.

[0034] In this embodiment, the button assembly can further position the limiting part 112 by cooperating with the protrusion 2111 and the fourth mounting hole 1121; at the same time, the cooperation between the protrusion 2111 and the fourth mounting hole 1121 can further prevent the button body 111 from falling out of the first mounting hole 211.

[0035] In some embodiments, the protrusions 2111 are located on both sides of the switch portion 120, and after the protrusions 2111 are inserted into the fourth mounting hole 1121, the protrusions 2111 protrude from the surface of the limiting portion 112, thereby limiting the switch portion 120. Specifically, the protrusions 2111 can limit the circuit board 122. However, this is not a limitation; after the protrusions 2111 are inserted into the fourth mounting hole 1121, the protrusions 2111 may also be flush with the surface of the limiting portion 112.

[0036] In some embodiments, button 110 further includes a deformable portion 113, such as Figure 8 and Figure 9 As shown. The deformation portion 113 is disposed between the button body 111 and the limiting portion 112, and in the direction from the button body 111 to the limiting portion 112, the deformation portion 113 is inclined in a direction away from the button body 111, as shown. Figure 8 As shown. For example, the button body 111, the limiting portion 112, and the deformable portion 113 are a single integrated structure. For example, the button body 111 is not easily deformed. For example, both the limiting portion 112 and the deformable portion 113 are made of soft material, thereby giving the deformable portion 113 good deformability. Soft materials include, for example, silicone, rubber, etc.

[0037] In this embodiment of the button assembly, an inclined deformation part 113 is provided between the button body 111 and the limiting part 112. When the button body 111 is subjected to force, the deformation part 113 can deform to reduce the force on the limiting part 112, thereby reducing the risk of damage at the connection between the button body 111 and the limiting part 112.

[0038] The handle in this embodiment includes a housing 210, such as... Figures 1-7 As shown. A receiving space 213 is formed within the housing 210, which is used to accommodate structures such as the traction wheel, traction rope, and instrument tube. The traction wheel, traction rope, and instrument tube are not shown in the figure. Not limited to this, the housing 210 also includes a button assembly, a suction valve, and a lever. The handle in this embodiment also includes a button assembly, which is a button assembly according to any of the technical solutions in this embodiment, such as... Figure 1 As shown. Figures 2-7 As shown, the housing 210 also has a first mounting hole 211, which is used to mount the button 110 of the button assembly, and the button assembly is accommodated in the receiving space 213.

[0039] The handle of this embodiment has a button assembly according to any of the technical solutions in this embodiment. The handle of this embodiment not only has a simple button structure, but also a simple button assembly step. The button can be installed on the housing in one step to prevent it from falling off.

[0040] The endoscope in this embodiment includes a handle and an insertion part, with the handle connected to the insertion part. The handle can be any endoscope handle according to any technical solution in this embodiment. The insertion part can be a structure in the prior art, which will not be described in detail here. The endoscope in this embodiment can be a bronchoscope, pyeloscope, esophagoscope, gastroscope, colonoscope, otoscope, rhinoscope, oral endoscope, laryngoscope, colposcope, laparoscope, arthroscope, etc. This embodiment does not specifically limit the type of endoscope.

[0041] The endoscope of this embodiment has an endoscope handle according to any of the technical solutions in this embodiment. The endoscope of this embodiment not only has a simple button structure, but also a simple button assembly step, which can achieve the anti-detachment installation of the button on the housing in just one step.

[0042] For example, the endoscope in this embodiment is a disposable endoscope. Using the endoscope handle of any of the technical solutions in this embodiment can also reduce the production cost of the endoscope.
