DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0029] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the objects before and after are in an "or" relationship.

[0030] In the embodiments of the present application, "proximal end" and "distal end" refer to the relative position of each component to the user in the use environment, wherein the end closer to the user is designated as "proximal end" and the end farther from the user is designated as "distal end".

[0031] In the prior art, the installation personnel performs the following operations to install the front end assembly: installing the lighting module and its cable in the front end seat of the insertion part, installing the camera module and its cable in the insertion seat of the insertion part, and finally performing glue injection or welding operations.

[0032] As can be seen, the number of components is large, the assembly efficiency is not high, and the stability is poor. Moreover, the chamber of the front end seat suitable for installing the lighting module is small in volume, which is not convenient for threading the cable, and the strength of a single cable is lower, which has a great risk of falling off.

[0033] The present application provides a front end assembly 100, please refer to Figure 1 The front end assembly 100 is used for the endoscope 1. Further, the front end assembly 100 can be applied to the distal end of the insertion part 200 of the endoscope 1. The insertion part 200 can have a driven bending section, and the front end assembly 100 has different orientations and positions with the operation of medical personnel.

[0034] Please refer to Figure 1 and Figure 2The front-end assembly 100 can include a front-end base 110, a camera module 120, an illumination module 130, and a cable 140. The camera module 120 and the illumination module 130 are arranged in the front-end base 110, and the camera module 120 and the illumination module 130 are electrically connected with the cable 140.

[0035] Please refer to Figure 3 The front-end base 110 can be integrally injection molded, which can improve the structural strength of the front-end base 110. The front-end base 110 can provide support for the camera module 120 and the illumination module 130 to improve the reliability of the front-end assembly 100. Specifically, the front-end base 110 is provided with an illumination cavity 111 and a camera cavity 112. The size and size of the illumination cavity 111 can be adapted to the illumination module 130, and the size and size of the camera cavity 112 can be adapted to the camera module 120. Moreover, the illumination cavity 111 and the camera cavity 112 are in communication with each other. For example, the illumination cavity 111 and the camera cavity 112 can be in communication along the radial direction of the front-end base 110. Alternatively, the illumination cavity 111 and the camera cavity 112 can be in communication along a direction intersecting the radial direction of the front-end base 110. This can eliminate the partition between the cavities, reduce the restriction of the partition on the volume of the cavity, and improve the available space size of the illumination module 130 and the camera module 120.

[0036] In addition, the front-end base 110 is not limited by structures such as partitions, and the installer can simultaneously install the camera module 120 and the illumination module 130. For example, the camera module 120 and the illumination module 130 are connected in advance, and then they are placed in the front-end base 110 together. This arrangement can improve the installation efficiency of the front-end assembly 100 and avoid the installation operation of the illumination module 130 in the narrow illumination cavity 111.

[0037] Please continue to refer to Figure 1 The camera module 120 is installed in the camera cavity 112. The camera module 120 can collect image information in front of the front-end assembly 100 and transmit it back to a display device for medical staff to observe and use. Further, the camera module 120 can be in the shape of a cube, and the camera cavity 112 can also be in the shape of a cube. The size of the camera cavity 112 is slightly larger than that of the camera module 120, and the camera module 120 can be installed in the camera cavity 112.

[0038] The camera module 120 can include a camera, which can be a complementary metal oxide semiconductor (CMOS) camera or a charge coupled device (CCD) camera, etc. The present embodiment does not limit the type and size of the camera.

[0039] Please continue to refer to Figure 1The lighting module 130 is installed inside the lighting cavity 111. The lighting module 130 can illuminate the front of the front-end component 100 so that the camera module 120 can capture image information with sufficient brightness. The lighting module 130 may include LED beads, etc., and this embodiment does not limit the structure and type of the lighting module 130.

[0040] In one embodiment, the number of illumination modules 130 can be at least two, such as two, three, or even more, without limitation. Simultaneously, the front-end base 110 can be provided with at least two illumination cavities 111, with each illumination cavity 111 corresponding to an illumination module 130, and each illumination module 130 can be disposed within its corresponding illumination cavity 111. Both illumination cavities 111 are connected to the camera cavity 112, and the at least two illumination cavities 111 can be distributed around the camera cavity 112. This allows the illumination modules 130 to fully illuminate all areas of the front end of the camera module 120, eliminating blind spots in front of the front-end base 110 and improving the acquisition effect of the camera module 120.

[0041] In the embodiments of this application, please refer to Figure 1 as well as Figure 4 Both the camera module 120 and the lighting module 130 are electrically connected to the same cable 140, which extends from the proximal end of the front-end base 110. For example, the cable 140 contains multiple strands of different core wires, each capable of supplying power to both the lighting module 130 and the camera module 120. The camera module 120 and the lighting module 130 are connected to the distal end of the cable 140, while the proximal end of the cable 140 extends to the operating section of the endoscope 1 and is electrically connected to the display device. With the lighting cavity 111 and the camera cavity 112 interconnected, the cable 140 can simultaneously electrically connect and supply power to both the camera module 120 and the lighting module 130, reducing the number of cables 140 and installation steps, thus improving installation efficiency. Compared to existing multiple cables, the cable 140 of this application has higher integration and greater strength, reducing the risk of detachment and improving structural stability.

[0042] In addition, cable 140 can also be used to transmit information. In one embodiment, some of the core wires can also transmit image information from camera module 120. In another embodiment, some of the core wires can transmit control information to lighting module 130 to control the brightness and color of lighting module 130, etc.

[0043] Preferably, the instrument tube 113 and the cable 140 are led out through the same channel proximal to the front end seat 110. On the basis of the mutual communication of the cavities of the front end seat 110, this arrangement can make the installer install the instrument tube 113, the camera module 120 and the illumination module 130 at the same time, and pass the cable 140 and the instrument tube 113, which greatly reduces the installation steps of the front end assembly 100, improves the integration, can reduce the risk of falling off, and improves the structural stability.

[0044] In an embodiment, please continue to refer to Figure 4 , the cable 140 can include a cable body 142 and a circuit board 141, and the cable body 142 is electrically connected to the circuit board 141. Wherein, the cable body 142 has a plurality of different core wires, and the circuit board 141 can be electrically connected to the plurality of core wires. The circuit board 141 includes a first electrical connection part 1411 and a second electrical connection part 1412, the first electrical connection part 1411 is located in the camera cavity 112 and is electrically connected to the camera module 120, and the second electrical connection part 1412 is located in the illumination cavity 111 and is electrically connected to the illumination module 130. The first electrical connection part 1411 and the second electrical connection part 1412 are respectively located in the camera cavity 112 and the illumination cavity 111, and are respectively connected to the camera module 120 and the illumination module 130. Exemplarily, the first electrical connection part 1411 and the second electrical connection part 1412 are both provided with a connection terminal, the connection terminal can connect the camera module 120 or the illumination module 130, and the connection terminal can fix the camera module 120 or the illumination module 130, which improves the fixing effect of the camera module 120 and the illumination module 130. The circuit board 141 not only improves the integration of the camera module 120 and the illumination module 130, facilitates installation, but also greatly reduces the number of connection structures of the cable 140, simplifying the installation steps.

[0045] In addition, the circuit board 141 also improves the structural strength of the front end assembly 100. The circuit board 141 as a support structure between the camera module 120 and the illumination module 130 can effectively disperse and withstand the impact force or vibration from the outside. This not only protects the camera module 120 and the illumination module 130 from damage, but also prolongs the service life of the front end assembly 100.

[0046] Further, please continue to refer to Figure 4, the circuit board 141 can be configured as a flexible printed circuit (FPC) having bendable, foldable and other characteristics, thereby improving the flexibility of the cable 140 distribution of the front-end assembly 100. The circuit board 141 further comprises an extension arm 1413 connected between the first electrical connection portion 1411 and the second electrical connection portion 1412, and the extension arm 1413 extends into the illumination cavity 111 from the camera cavity 112. The extension arm 1413 also has a variable capability, so that it can conform to the layout requirements of different cavities in the front-end seat 110. The extension arm 1413 can reduce the limitations of the relative positions among the cable 140, the illumination module 130 and the camera module 120, thereby greatly improving the flexibility of the relative position arrangement of the camera module 120 and the illumination module 130.

[0047] It can be understood that, in the axial direction of the front-end seat 110, the extension arm 1413 extends from the proximal end to the distal end of the front-end seat 110. The extension arm 1413 can adjust the relative position of the illumination module 130 in the axial direction, so that the illumination module 130 can be arranged close to the distal end of the front-end seat 110, which can eliminate other limitations on the illumination area of the illumination module 130 and improve the illumination effect of the illumination module 130.

[0048] In the embodiments of the present application, please refer to Figure 2 The front-end seat 110 can further be provided with an instrument cavity 114 penetrating through the front-end seat 110 in the axial direction, the instrument cavity 114 is communicated with the camera cavity 112, and the instrument tube 113 is arranged in the instrument cavity 114 and extends out of the proximal end of the front-end seat 110. This can eliminate the partition plate between the instrument cavity 114 and the camera cavity 112, reduce the limitation of the partition plate on the cavity volume, and improve the available space size of the instrument tube 113 and the camera module 120. In addition, the instrument cavity 114, the camera cavity 112 and the illumination cavity 111 are communicated with each other, so that the front-end seat 110 integrates a larger space, which provides more convenience for the arrangement of the instrument tube 113 and reduces the installation space. In addition, the instrument tube 113 has a deformation capability, and the front-end seat 110 can provide space for the deformation of the instrument tube 113, so as to pass through different specifications of instruments, improve the accuracy and safety of the operation.

[0049] In the embodiments of the present application, please refer to Figure 2 and Figure 3, the camera cavity 112 and the instrument cavity 114 are open on the sides facing away from each other. Open means that the camera cavity 112 and the instrument cavity 114 are exposed to the outside in the direction away from each other. The open setting facilitates process operations such as glue injection. The installation worker can easily enter the inside of the cavity through the open port to perform the glue injection operation, ensuring that the sealing or other functional requirements are met. This open setting can reduce the installation difficulty and improve the work efficiency.

[0050] During assembly, due to the open setting of the front end seat 110, the operator can clearly see the butt joint of each component, ensuring that there is no misalignment, looseness or omission problem. This helps to discover and correct potential installation problems in time, thereby avoiding failures or reliability reduction caused by improper installation.

[0051] In an embodiment, please refer to Figure 3 , the front end seat 110 is provided with a first opening 115 and a second opening 116, both of which extend along the axial direction of the front end seat 110, the first opening 115 is radially connected to the camera cavity 112, and part of the camera module 120 is arranged at the first opening 115; the second opening 116 is radially connected to the instrument cavity 114, and part of the instrument tube 113 is arranged at the second opening 116. The first opening 115 and the second opening 116 are radially arranged along the front end seat 110, and part of the camera module 120 and the instrument tube 113 can be directly installed or embedded in the first opening 115 and the second opening 116. The camera module 120 and the instrument tube 113 not only occupy the original peripheral space of the front end seat 110, but also optimize the layout, providing greater freedom for the camera module 120 and the instrument tube 113, so that the size of the camera module 120 and the instrument tube 113 can be further improved without increasing the volume of the front end seat 110, thereby optimizing the camera performance and image quality. It also facilitates observation and operation.

[0052] In the embodiment of the present application, please continue to refer to Figure 3 , the front end seat 110 is provided with a first limiting protrusion 117 and a second limiting protrusion 118, which are arranged in the front end seat 110 and limit the movement of at least one of the camera module 120, the illumination module 130 and the instrument tube 113 in the front end seat 110, and the first limiting protrusion 117 and the second limiting protrusion 118 can provide support force for the camera module 120, the illumination module 130 and the instrument tube 113, effectively withstand the impact force or vibration from the outside, and improve the fixing effect of the camera module 120, the illumination module 130 and the instrument tube 113. In addition, the first limiting protrusion 117 and the second limiting protrusion 118 can also provide a bonding basis for them during subsequent glue injection or welding operation, to improve the gluing or welding effect.

[0053] In one embodiment, please refer to Figure 1 and Figure 3 The first limiting protrusion 117 is arranged between the instrument cavity 114 and the camera cavity 112, and can provide radial limitation for at least one of the camera module 120 and the instrument tube 113. In one case, the first limiting protrusion 117 can provide radial limitation for the instrument tube 113. Specifically, the surface of the first limiting protrusion 117 close to the instrument tube 113 is configured as a curved surface. For example, the curved surface is tangent to the radial direction of the front end seat 110. The curved surface is arranged corresponding to the instrument tube 113, and abuts against the outer tube wall of the instrument tube 113, limiting the radial movement of the instrument tube 113.

[0054] In another case, the first limiting protrusion 117 can abut against the camera module 120, and limit the radial movement of the camera module 120 along the front end seat 110, i.e. limit the movement of the camera module 120 towards the direction close to the instrument tube 113. This can provide limiting effect for the camera module 120, and improve the fixing effect of the camera module 120.

[0055] In another embodiment, please refer to Figure 1 and Figure 3 The second limiting protrusion 118 is arranged between the camera cavity 112 and the illumination cavity 111, and can limit the movement of the camera module 120 along the first direction, which intersects the radial direction of the front end seat 110. The second limiting protrusion 118 effectively restricts the movement range of the camera module 120, and can limit the movement of the camera module 120 along the first direction. This hindering effect directly limits the movement of the camera module 120 beyond the predetermined range, thereby ensuring the stability and accuracy of the camera module 120 during operation.

[0056] In another embodiment, the first limiting protrusion 117 and the second limiting protrusion 118 can cooperate with each other and act on the camera module 120 and the instrument tube 113. For example, the first limiting protrusion 117 and the second limiting protrusion 118 can limit the movement of the camera module 120 in different directions, thereby improving the limiting effect of the camera module 120, which will not be described here.

[0057] In addition, please refer to Figure 1 and Figure 3The lighting module 130 is fixed between the first limiting protrusion 117 and the second limiting protrusion 118, the first limiting protrusion 117 and the second limiting protrusion 118 can be arranged on different sides of the lighting module 130, and the first limiting protrusion 117 and the second limiting protrusion 118 can simultaneously act on different sides of the lighting module 130, so that the lighting module 130 can be relatively fixed. Further, one side of the lighting module 130 is provided with a cavity wall, and the first limiting protrusion 117 and the second limiting protrusion 118 are oppositely arranged. The cavity wall, the first limiting protrusion 117 and the second limiting protrusion 118 simultaneously act on the lighting module 130, and in addition, the camera module 120 or the instrument tube 113 can also limit the lighting module 130, which can avoid the radial movement of the lighting module 130.

[0058] To achieve the above object and other related objects, the present application provides an insertion part 200, please refer to Figure 5 The insertion part 200 comprises the aforementioned front end assembly 100. Thus, the insertion part 200 has the beneficial effects of any of the above-mentioned solutions.

[0059] To achieve the above object and other related objects, the present application provides an endoscope 1, please refer to Figure 5 The endoscope 1 comprises the aforementioned insertion part 200. Thus, the endoscope 1 has the beneficial effects of any of the above-mentioned solutions, which will not be repeated here. The endoscope 1 can be a bronchoscope, a nephroscope, an esophagoscope, a gastroscope, a colonoscope, an otoscope, a nasoscope, an oral mirror, a laryngoscope, a vaginal mirror, a laparoscope, an arthroscope, etc. The present application does not specifically limit the type of endoscope 1 and the implementation scenario of the endoscope 1 system.

[0060] The technical scheme of the utility model can achieve the following beneficial effects: the illumination cavity 111 and the camera cavity 112 of the front end seat 110 are in communication with each other, a partition plate is avoided between the illumination cavity 111 and the camera cavity 112, and the space size of the illumination cavity 111 and the camera cavity 112 is improved, the internal space of the front end seat 110 can be optimized, and then a larger illumination module and a camera module can be arranged. Moreover, the installation personnel can simultaneously install the camera module 120 and the lighting module 130. For example, the camera module 120 and the lighting module 130 are connected in advance, and then they are placed in the front end seat 110 together. The arrangement can improve the installation efficiency of the front end assembly 100, and avoid the installation operation of the lighting module 130 in the narrow illumination cavity 111.

[0061] In addition, on the basis that the illumination cavity 111 and the camera cavity 112 are in communication with each other, the cable 140 can simultaneously electrically connect the camera module 120 and the illumination module 130, and supply power or transmit signals for the camera module 120 and the illumination module 130, which can reduce the number of cables 140 and installation steps, and further improve installation efficiency. Compared with the existing multiple cables 140, the cable 140 of the present application has higher integration and greater strength, which can reduce the risk of falling off and improve structural stability.
