Description

Technical Field

[0001] This utility model relates to the field of medical instrument technology, and more specifically, to a capsule endoscope. Background Technology

[0002] A capsule endoscope is an endoscope shaped like a capsule; it is a medical instrument used to examine the human intestines.

[0003] In existing technology, capsule endoscopes mainly consist of an outer shell and a capsule core. The outer shell is formed by bonding an upper shell and a lower shell together with adhesive. The capsule core is inserted into the outer shell, and a key component is the lamp plate. The lamp plate is connected to the endoscope mount via an FPC (Flexible Printed Circuit) cable. The lamp plate springs back under the action of the FPC cable, causing the lamp plate cover, which is pressed against the lamp plate, to spring back as well. Thus, during the bonding of the upper and lower shells, external force or tooling is used to press the upper shell down to prevent the lamp plate cover from springing back and causing the upper shell to float, thus preventing the upper and lower shells from properly engaging. The above-described outer shell bonding method has the following disadvantages:

[0004] (1) The upper shell needs to be pressed with external force or tooling, which will make the shell assembly cumbersome and the production efficiency low.

[0005] (2) The upper shell is pressed by external force or tooling and is operated manually. There is human error, which leads to the upper shell and lower shell not being properly fastened, resulting in poor assembly accuracy of the shell.

[0006] (3) If the lamp cover is not fixed, the upper shell will still spring up, which will reduce the glue bonding area between the upper shell and the lower shell. The connection between the upper shell and the lower shell is not firm, and the risk of the outer shell disintegrating is high.

[0007] (4) After long-term use, the glue between the upper and lower shells is prone to failure, which will cause the capsule core to break off from the shell.

[0008] In summary, how to solve the above-mentioned shortcomings of the outer shell bonding method of capsule endoscope is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0009] In view of this, the purpose of this utility model is to provide a capsule endoscope that can solve the problem of the upper shell floating up when the outer shell is bonded due to the self-rebound of the device inside the capsule core without the need for external force or tooling.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A capsule endoscope, comprising:

[0012] The upper and lower shells are open at both ends and are glued together to form an outer shell.

[0013] The capsule core is located inside the outer shell. The upper end of the capsule core has a lamp cover for preventing the lamp panel from rebounding. The lamp cover is located at the opening end of the lower shell and is connected to the lower shell by a connecting assembly.

[0014] Preferably, the lower shell has a convex stop at its opening end, and the upper shell has a concave stop at its opening end. The convex stop and the concave stop are fitted together and bonded together with adhesive.

[0015] Preferably, the lower end of the lamp cover has an outer edge, which is located between the end faces of the concave stop and the convex stop.

[0016] Preferably, the connecting component is detachably connected between the outer edge and the protruding stop.

[0017] Preferably, the connecting component includes a first snap-fit ​​portion and a second snap-fit ​​portion, the first snap-fit ​​portion being disposed at the lower end of the outer edge, and the second snap-fit ​​portion being disposed on the side wall of the protruding stop and snap-fitting with the first snap-fit ​​portion.

[0018] Preferably, the first snap-fit ​​part is a buckle, and the second snap-fit ​​part is a slot.

[0019] Preferably, the buckle includes a lug and a locking block. The lug is located at the lower end of the outer edge along the thickness direction of the outer edge, and the locking block is located on the side of the lug facing the protruding stop, and the locking block is engaged in the locking groove.

[0020] Preferably, the lug and the locking block are an integral structure, and the integral structure is made of an elastic material.

[0021] Preferably, there are multiple connecting components, which are evenly arranged around the axis of the lamp cover.

[0022] Preferably, the upper shell is an optical material component.

[0023] The capsule endoscope provided by this utility model can be glued together at opposite ends of the upper and lower shells to form an outer shell. When the outer shells (i.e., the upper and lower shells) are glued together, the lamp cover in the capsule core is connected to the lower shell through a connecting component. Even if the lamp cover is fixedly connected to the lower shell, the lamp cover will not bounce upward due to the rebound of the lamp plate, which can avoid the phenomenon that the upper shell floats up and the upper and lower shells cannot be properly fastened.

[0024] Therefore, the capsule endoscope provided by this utility model has the following beneficial effects:

[0025] (1) The lamp cover is fixedly connected to the lower shell using a connecting component. When the outer shell is bonded, there is no need to use external force or tooling to press the upper shell, making the assembly of the outer shell simple and convenient, thereby improving production efficiency.

[0026] (2) No external force or tooling is needed to press the upper shell, and there is no human operation error. Instead, the lamp cover and the lower shell are fixed together by connecting components, which can ensure that the lamp cover will not spring up and cause the upper shell to float, thus ensuring that the upper shell and the lower shell are properly fastened and improving the assembly accuracy of the outer shell.

[0027] (3) The lamp cover is fixedly installed. The lamp cover will not bounce up and cause the upper shell to float. This can increase the glue bonding area between the upper shell and the lower shell, improve the firmness of the connection between the upper shell and the lower shell, and reduce the risk of shell disintegration.

[0028] (4) After long-term use, if the glue fails and the outer shell disintegrates, the lamp cover at the top of the capsule core will still be fixed together with the lower shell through the connecting component. Even if the capsule core and the lower shell are still connected as one, the capsule endoscope can be prevented from completely disintegrating. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] The core of this invention is to provide a capsule endoscope that can solve the problem of the upper shell floating up when the outer shell is bonded due to the self-rebound of the internal components of the capsule core without the need for external force or tooling.

[0042] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on this application. In addition, "first," "second," "third," and "fourth" are only used to describe effects and should not be construed as indicating or implying relative importance.

[0043] Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 This application provides a capsule endoscope, including an outer shell 1 and a capsule core 2. The upper shell 11 and the lower shell 12 have open ends at opposite ends and are bonded together to form the outer shell 1. The capsule core 2 is located inside the outer shell 1, and its upper end has a lamp cover 21 to prevent the lamp plate 22 from rebounding. The lamp cover 21 is located at the open end of the lower shell 12 and is connected to the lower shell 12 via a connecting assembly 3.

[0044] It should be noted that, as Figure 2 and Figure 3As shown, the lower end of the upper shell 11 is an open end, and the upper end of the lower shell 12 is an open end. Before the upper shell 11 and the lower shell 12 are fastened together, the capsule core 2 is placed in the lower shell 12 through the open end of the lower shell 12. Then, the lower end of the upper shell 11 and the upper end of the lower shell 12 are fastened together. Then, the opposite ends of the upper shell 11 and the lower shell 12 can be glued together to form an outer shell 1. The capsule core 2 is disposed inside the outer shell 1. In addition, the upper end of the capsule core 2 is the lens end, which has a lamp cover 21. The lamp cover 21 is used to fit on the lens assembly. The lower end surface of the lamp cover 21 abuts against the lamp plate 22, and the lamp cover 21 is located at the open end of the lower shell 12 to cover the components inside the capsule core 2 inside the lower shell 12.

[0045] In the capsule endoscope provided in the above embodiment, when the outer shell 1 (i.e., the upper shell 11 and the lower shell 12) is bonded, the lamp cover 21 in the capsule core 2 is connected to the lower shell 12 through the connecting component 3. Even if the lamp cover 21 is fixedly connected to the lower shell 12, the lamp cover 21 will not bounce upward due to the rebound effect of the lamp plate 22, which can avoid the phenomenon that the upper shell 11 floats up and the upper shell 11 and the lower shell 12 cannot be properly fastened.

[0046] Therefore, the capsule endoscope provided in the above embodiments has the following advantages:

[0047] First, the lamp cover 21 is fixedly connected to the lower shell 12 by the connecting component 3. When the outer shell 1 is glued, there is no need to use external force or tooling to press the upper shell 11, which makes the assembly of the outer shell 1 simple and convenient, thereby improving production efficiency.

[0048] Secondly, there is no need to use external force or tooling to press the upper shell 11, and there is no human operation error. Instead, the connecting component 3 is used to fix the lamp cover 21 and the lower shell 12 together, which can ensure that the lamp cover 21 will not spring up and cause the upper shell 11 to float up. This ensures that the upper shell 11 and the lower shell 12 are properly fastened, improving the assembly accuracy of the outer shell 1.

[0049] Third, the lamp cover 21 is fixedly installed, and the lamp cover 21 will not bounce up and cause the upper shell 11 to float. This can increase the glue bonding area between the upper shell 11 and the lower shell 12, improve the firmness of the connection between the upper shell 11 and the lower shell 12, and reduce the risk of the outer shell 1 disintegrating.

[0050] Fourth, after long-term use, if the glue fails and the outer shell 1 disintegrates, the lamp cover 21 at the upper end of the capsule core 2 will still be fixed together with the lower shell 12 through the connecting component 3. Even if the capsule core 2 and the lower shell 12 are still connected as one unit, the capsule endoscope can be prevented from completely disintegrating.

[0051] Based on the above embodiments, as a further preferred option, please refer to... Figure 2 , Figure 3 and Figure 4The lower shell 12 has a convex stop 121 at its open end, and the upper shell 11 has a concave stop 111 at its open end. The convex stop 121 and the concave stop 111 fit together and are bonded together with glue.

[0052] It should be noted that the convex stop 121 is composed of a protruding short cylinder and an end face, and the concave stop 111 is composed of a short hole and an end face. When the upper shell 11 and the lower shell 12 are fastened and bonded, the short hole of the concave stop 111 in the upper shell 11 and the short cylinder of the convex stop 121 in the lower shell 12 are tightly fitted together, and the end faces of the concave stop 111 and the convex stop 121 are tightly fitted together.

[0053] Thus, the two open ends of the upper shell 11 and the lower shell 12 are fastened with a stop structure, which not only prevents misalignment when the upper shell 11 and the lower shell 12 are fastened, but also increases the bonding area of ​​the upper shell 11 and the lower shell 12, further improving the firmness of the connection between the upper shell 11 and the lower shell 12 and reducing the risk of the outer shell 1 disintegrating.

[0054] Based on the above embodiments, as a further preferred option, please refer to... Figure 5 The lower end of the lamp cover 21 is provided with an outer edge 211, which is located between the end faces of the concave stop 111 and the convex stop 121.

[0055] Thus, when the concave stop 111 and the convex stop 121 are fastened together, their end faces press against the outer edge 211 of the lamp cover 21. After the concave stop 111 and the convex stop 121 are glued together, the lamp cover 21 can be firmly installed at the joint between the upper shell 11 and the lower shell 12. On the one hand, this can prevent the lamp cover 21 from floating after the outer shell 1 is fastened together, thereby further reducing the risk of the outer shell 1 disintegrating. On the other hand, it can prevent the lamp cover 21 from shifting and affecting the focus, thus facilitating accurate focus.

[0056] Based on the above embodiments, as a further preferred option, please refer to... Figure 6 The connecting component 3 is detachably connected between the outer edge 211 and the protruding stop 121.

[0057] Understandably, since the outer edge 211 of the lamp cover 21 presses against the end face of the protruding stop 121 of the lower shell 12, the connecting component 3 is connected between the outer edge 211 and the protruding stop 121. That is, the connecting component 3 is positioned near the pressing position of the outer edge 211 and the protruding stop 121. In this way, on the one hand, the connection between the lamp cover 21 and the protruding stop 121 can be made more secure and stable, that is, the connection between the lamp cover 21 and the lower shell 12 can be improved; on the other hand, the connecting component 3, the lower shell 12 and the lamp cover 21 can be compactly integrated into one unit to fit the small internal space of the outer shell 1.

[0058] In addition, the connecting component 3 is detachable, which allows the lamp cover 21 and the lower shell 12 to be detachably connected, making it convenient to disassemble and maintain the lamp cover 21 and the lower shell 12.

[0059] In one specific embodiment, the connecting component 3 is a bolt, a first mounting hole is provided in the thickness direction of the outer edge 211, and a second mounting hole corresponding to the first mounting hole is provided on the end face of the convex stop 121. The bolt passes through the first mounting hole and is fastened in the second mounting hole, thereby realizing a detachable connection between the lamp cover 21 and the lower shell 12.

[0060] Furthermore, in another specific embodiment, the connecting component 3 includes a first snap-fit ​​portion and a second snap-fit ​​portion. The first snap-fit ​​portion is located at the lower end of the outer edge 211, and the second snap-fit ​​portion is located on the side wall of the protruding stop 121 and snaps with the first snap-fit ​​portion.

[0061] Thus, the connecting component 3 is a snap-fit ​​structure composed of the first snap-fit ​​part and the second snap-fit ​​part. The lamp cover 21 and the lower shell 12 are connected by a snap-fit ​​structure. Compared with the installation of bolt alignment and tightening, the snap-fit ​​structure is simple and convenient to operate, making the disassembly, assembly and maintenance of the lamp cover 21 and the lower shell 12 simpler and more convenient.

[0062] It should also be noted that the first snap-fit ​​part is located at the lower end of the outer edge 211, and the second snap-fit ​​part is located on the side wall of the convex stop 121. This avoids interference between the two snap-fit ​​parts. The outer edge 211 abuts against the end faces of the concave stop 111 and the convex stop 121, so that while the upper shell 11 and the lower shell 12 press the lamp cover 21, the lamp cover 21 and the lower shell 12 are fixed together. This improves the firmness and stability of the lamp cover 21 installation and effectively prevents the components (lamp cover 21 and lamp plate 22, etc.) inside the capsule core 2 from springing back. Therefore, whether the outer shell 1 is being glued or after the outer shell 1 is assembled, the upper shell 11 will not float up due to the spring force of the lamp cover 21, thereby improving the accuracy and reliability of the assembly of the outer shell 1.

[0063] Based on the above embodiments, as a further preferred option, please refer to... Figure 3 , Figure 4 and Figure 6 The first snap-fit ​​part is a snap-fit ​​31, and the second snap-fit ​​part is a snap-fit ​​slot 32.

[0064] It is understandable that a buckle 31 is provided at the lower end of the outer edge 211, and a slot 32 is provided on the side wall of the convex stop 121 (i.e. the side wall of the short cylinder). The buckle 31 and the slot 32 are adapted to engage, so as to achieve the detachable connection between the lamp cover 21 and the lower shell 12 through the connecting component 3, while avoiding interference from the connecting component 3 to the tight fit between the short cylinder of the convex stop 121 and the short hole of the concave stop 111, and ensuring that there is a large bonding area between the upper shell 11 and the lower shell 12.

[0065] Based on the above embodiments, and considering the specific structure of the buckle 31, for further preferred embodiments, please refer to... Figure 4 The buckle 31 includes a support ear 311 and a locking block 312. The support ear 311 is located at the lower end of the outer edge 211 along the thickness direction of the outer edge 211. The locking block 312 is located on the side of the support ear 311 facing the protruding stop 121 and is engaged in the locking groove 32.

[0066] In this way, the lug 311 can effectively utilize the space under the lamp cover 21. The locking block 312 is set on the side of the lug 311 facing the protruding stop 121, which can better align and engage the locking block 312 with the locking groove 32 on the side wall of the protruding stop 121, ensuring that the locking block 312 and the locking groove 32 are engaged in place.

[0067] Based on the above embodiments, as a further preferred embodiment, the lug 311 and the locking block 312 are an integral structure, and the integral structure is made of an elastic material. That is to say, the buckle 31 structure is stable, and the elastic deformation of the buckle 31 can be used to realize the quick engagement and disengagement of the buckle 31 and the slot 32, thereby greatly improving the convenience of installation and disassembly of the lamp cover 21 and the rear shell.

[0068] Based on the above embodiments, as a further preferred embodiment, multiple connecting components 3 are provided, and the multiple connecting components 3 are evenly arranged around the axis of the lamp cover 21.

[0069] Specifically, multiple first snap-fit ​​parts are evenly arranged around the axis of the lamp cover 21 at the lower end of the outer edge 211, and multiple second snap-fit ​​parts are evenly arranged around the axis of the lamp cover 21 on the side wall of the protruding stop 121 of the rear shell, so that the multiple second snap-fit ​​parts correspond one-to-one with the multiple first snap-fit ​​parts and engage in a snap-fit ​​fit. In this arrangement, each connecting component 3 is evenly stressed, and the firmness and reliability of the connection between the lamp cover 21 and the rear shell are improved.

[0070] Based on the above embodiments, as a further preferred embodiment, the upper shell 11 is made of optical material. That is, the upper shell 11 is an optically transparent shell, equivalent to a transparent end cap, to avoid obstructing the lens field of view inside the capsule core 2 and to ensure that images can be clearly captured inside the digestive tract.

[0071] It should be noted that in this application, since there is no need to use external force or tooling to press the upper shell 11, the upper shell 11 will not have defects such as scratches, dirt, or minor deformation, thereby improving the production quality of capsule endoscopes.

[0072] In this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0073] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0074] The capsule endoscope provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
