[0033] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely below in combination with the specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present application.

[0034] The technical solutions disclosed by the various embodiments of the present application will be described in detail below in combination with the drawings.

[0035] In order to solve the technical problem that the front-end functional devices of the endoscope are easily affected by static electricity in the related art, the present application provides an endoscope.

[0036] As shown in the figure, Figures 1-13 The endoscope disclosed by the embodiment of the present application comprises a front-end function module 100, a first circuit board 200 and a first electrostatic conduction member 300, wherein:

[0037] The front-end functional module 100 is a main functional component of the endoscope, which is arranged in the working end of the endoscope to implement lesion examination, minimally invasive surgery and other diagnostic and therapeutic means on one side of the working end of the endoscope. Optionally, the front-end functional module 100 includes a camera 110 and a light source, and of course, the specific composition of the front-end functional module 100 is not limited in the present application. It should be noted that the working end of the endoscope refers to the end portion of the endoscope that extends into the patient's body to perform work.

[0038] The front-end functional module 100 is connected with the first circuit board 200, and the first circuit board 200 can supply power to the front-end functional module 100 and realize signal interaction of the front-end functional module 100.

[0039] The first electrostatic flow guide 300 is a main component for discharging static electricity in the endoscope, which is also arranged in the working end of the endoscope to facilitate the absorption and flow guide of static electricity generated by the front-end functional module 100 also located in the working end of the endoscope. The first electrostatic flow guide 300 is connected with the first circuit board 200, and the first electrostatic flow guide 300 is grounded through the first circuit board 200. In this layout, the first electrostatic flow guide 300 can form a static electricity discharge path with the ground network of the first circuit board 200, and the static electricity is discharged through the ground network.

[0040] The first electrostatic flow guide 300 is arranged adjacent to the front-end functional module 100, which can further improve the performance of the first electrostatic flow guide 300 in absorbing static electricity. Further, the first electrostatic flow guide 300 can be arranged spaced apart from the front-end functional module 100 to avoid interference between the installation layouts of the two.

[0041] The endoscope usually includes an inner tube body 400 and an outer tube body. The inner tube body 400 can serve as a mounting base for the first circuit board 200, the front-end functional module 100 and the first electrostatic flow guide 300 to provide support. The outer tube body is sleeved on the outer periphery of the inner tube body 400, the first circuit board 200 and other components to provide protection.

[0042] At the working end of the endoscope, the inner tube body 400 can be provided with a working port 410. In this way, medical instruments such as scissors and forceps can be sent into the patient's body through the transmission channel in the inner tube body 400, and surgical operations can be performed at the working port 410. Of course, the transmission channel is also used to transport cleaning liquid, which is sprayed on the lesion site of the patient through the working port 410 to achieve cleaning.

[0043] As shown in Figure 1 and Figure 3 , the viewing direction of the front-end functional module 100 of the present application is consistent with the direction of the working port 410, so that the viewing operation can be performed in real time when the surgical operation is performed.

[0044] As can be seen from the above analysis, in the endoscope disclosed in the embodiments of the present application, the first electrostatic flow member 300 is grounded through the first circuit board 200, and the first electrostatic flow member 300 is arranged adjacent to the front-end functional module 100. Based on the principle that charges preferentially select a path with smaller impedance, the static electricity generated by the devices in the front-end functional module 100 is absorbed by the first electrostatic flow member 300 and is conducted away by the ground network on the first circuit board 200, that is, the first electrostatic flow member 300 and the ground network of the first circuit board 200 form a static electricity discharge path, and the first electrostatic flow member 300 is equivalent to increasing the area of the grounding plane in the endoscope. Therefore, the front-end functional module 100 can be effectively prevented from being interfered by static electricity, so as to optimize the quality of the image collected by the endoscope and avoid damage to the light source.

[0045] In order to facilitate the arrangement of the first electrostatic flow member 300 adjacent to the front-end functional module 100, in an optional scheme, the first circuit board 200 is a flexible board, and the first electrostatic flow member 300 is arranged adjacent to the front-end functional module 100 by at least one bending of the first circuit board 200. It should be understood that the bending can improve the structural compactness of the first circuit board 200, and in the case of substantially the same space occupation, the extension area of the first circuit board 200 after bending is greatly improved, so as to strengthen the performance of the first circuit board 200. At the same time, the static electricity discharge function realized by the first electrostatic flow member 300 according to the embodiments of the present application can effectively reduce the static electricity discharge pressure of the first circuit board 200. In this case, only one layer of ground line can be arranged on the first circuit board 200, which can also meet the static electricity discharge requirements inside the endoscope, thereby effectively reducing the thickness of the first circuit board 200 and further strengthening the flexibility of the first circuit board 200.

[0046] In the embodiments of the present application, there are various structural layout schemes inside the endoscope, which are not limited in the embodiments of the present application.

[0047] The embodiments of the present application provide a first endoscope, as shown in Figure 2 and Figure 3 The first circuit board 200 includes a board main body 210 and a first sub-board 220 connected with each other, the front-end functional module 100 is arranged at a first end of the board main body 210, the first end of the board main body 210 extends to the working end of the endoscope, the first electrostatic flow member 300 is connected with the first sub-board 220 and arranged adjacent to the first end of the board main body 210; the first sub-board 220 is parallel to the extension direction of the board main body 210, and the first sub-board 220 is bent towards the board main body 210 to be stacked with the board main body 210, so as to arrange the first electrostatic flow member 300 adjacent to the front-end functional module 100.

[0048] It should be understood that the first sub-plate 220 of such a structural layout is consistent with the extension direction of the plate body 210, and after being folded in opposite directions, the first electrostatic flow member 300 provided on the first sub-plate 220 can be closer to the extension path of the plate body 210. In addition, the first electrostatic flow member 300 is arranged adjacent to the first end of the plate body 210, and the front-end functional module 100 is arranged at the first end of the plate body 210. Therefore, the first electrostatic flow member 300 is adjacent to the front-end functional module 100 in the folded first circuit board 200, thereby smoothly absorbing static electricity.

[0049] At the same time, the first sub-plate 220 and the plate body 210 arranged in a stacked manner can improve the integration of the first circuit board 200, thereby optimizing the structural compactness inside the endoscope.

[0050] Further, as shown in Figure 2 and Figure 4 , the first electrostatic flow member 300 is folded towards the first sub-plate 220 and arranged in a stacked manner, so that the first electrostatic flow member 300 is arranged adjacent to the front-end functional module 100. In this arrangement, the first electrostatic flow member 300 is folded to be arranged in a stacked manner with the first sub-plate 220 based on the folding of the first sub-plate 220 to the extension path of the plate body 210, so that the first electrostatic flow member 300 is directly located on the extension path of the plate body 210. Obviously, the first electrostatic flow member 300 can be further adjacent to the front-end functional module 100, thereby optimizing the effect of absorbing static electricity.

[0051] At the same time, the first electrostatic flow member 300 and the first sub-plate 220 arranged in a stacked manner can further optimize the structural compactness inside the endoscope.

[0052] Further, as shown in Figures 2-4 , the first electrostatic flow member 300 is folded towards the front-end functional module 100, so that the first electrostatic flow member 300 is arranged opposite to the front-end functional module 100. Such a structural layout can further shorten the distance between the first electrostatic flow member 300 and the front-end functional module 100, thereby further improving the performance of the first electrostatic flow member 300 in absorbing static electricity.

[0053] The second endoscope provided by the embodiment of the present application is as shown in Figures 5-8As shown, the first circuit board 200 includes a main board body 210 and a first sub-board 220 connected to each other. The front-end functional module 100 is disposed at the first end of the main board body 210. The first end of the main board body 210 extends to the working end of the endoscope. The first sub-board 220 is disposed adjacent to the first end of the main board body 210. The first electrostatic conductive member 300 is connected to the first sub-board 220. The extension direction of the first sub-board 220 forms a preset angle with the extension direction of the main board body 210. The first sub-board 220 is bent relative to the main board body 210 and is disposed around the main board body 210 so that the first electrostatic conductive member 300 is disposed adjacent to the front-end functional module 100.

[0054] In this structural layout, the main body 210 is the main part of the first circuit board 200, which serves the functions of power supply and signal interaction. The first sub-board 220 is arranged around the main body 210, thereby increasing the area of ​​the first circuit board 200 and improving its performance. At the same time, the surrounding shape of the first sub-board 220 forms a closed-loop structure, which can provide better support for the first electrostatic discharge component 300.

[0055] Among them, such as Figure 6 As shown, the extension direction of the first sub-plate 220 is at a 90° angle to the extension direction of the main plate 210, which facilitates the first sub-plate 220 being arranged around the main plate 210. Of course, the specific angle between the first sub-plate 220 and the main plate 210 is not limited in this embodiment; it can also be 30°, 55°, 118°, 150°, etc., as long as the first sub-plate 220 can be arranged around the main plate 210.

[0056] Furthermore, Figures 6-8 As shown, when the first sub-board 220 is arranged around the main body 210, the first electrostatic discharge component 300 can be arranged opposite to the front-end functional module 100 to shorten the distance between the first electrostatic discharge component 300 and the front-end functional module 100, thereby improving the electrostatic discharge component 300's performance in absorbing static electricity.

[0057] This application provides a third type of endoscope, such as... Figures 9-11 As shown, the first circuit board 200 includes a board body 210 and a first sub-board 220. The front-end functional module 100 is disposed at the first end of the board body 210, and the first end of the board body 210 extends to the working end of the endoscope. The first end of the first sub-board 220 is connected to the board body 210, and the second end of the first sub-board 220 extends to be disposed adjacent to the front-end functional module 100. The first electrostatic conductive member 300 is disposed at the second end of the first sub-board 220.

[0058] In the structural layout, the plate body 210 and the first main plate are in a separated structure, so that the processing convenience of the first circuit board 200 is optimized and the processing difficulty of the first circuit board 200 is reduced. Specifically, the plate body 210 and the first sub plate 220 can be fixedly connected through welding, clamping or the like. In the case where the first sub plate 220 is connected with the plate body 210, since the second end of the first sub plate 220 extends to be adjacent to the front-end functional module 100, and the first electrostatic flow member 300 is arranged at the second end of the first sub plate 220, it is ensured that the first electrostatic flow member 300 is also adjacent to the front-end functional module 100.

[0059] Further, as shown in Figure 10 and Figure 11 , in the case where the first sub plate 220 is connected with the plate body 210, the first electrostatic flow member 300 can be arranged opposite to the front-end functional module 100, so as to shorten the distance between the first electrostatic flow member 300 and the front-end functional module 100, thereby improving the performance of the first electrostatic flow member 300 in absorbing static electricity.

[0060] Further, as shown in Figure 10 and Figure 11 , the first circuit board 200 further includes a second electrostatic flow member 201 and a third electrostatic flow member 202, the second electrostatic flow member 201 is arranged on the plate body 210, the third electrostatic flow member 202 is arranged on the first sub plate 220, and the plate body 210 and the first sub plate 220 are connected through the second electrostatic flow member 201 and the third electrostatic flow member 202.

[0061] In this arrangement, the second electrostatic flow member 201 and the third electrostatic flow member 202 can not only realize the connection relationship between the plate body 210 and the first sub plate 220, but also increase the area of the structure for absorbing static electricity in the endoscope, which is equivalent to increasing the area of the bottom contact plane in the endoscope, thereby further improving the performance of the endoscope in discharging static electricity.

[0062] In the related art, the first circuit board 200 is usually in a flat shape, and the front-end functional module 100 is arranged in the mounting surface in the flat shape, which is equivalent to being arranged along the radial direction of the endoscope. Since the mounting space in the radial direction of the endoscope is limited, the front-end functional module 100 will interfere with the outer tube body of the endoscope, which will increase the installation difficulty of the front-end functional module 100.

[0063] Based on this, in any one of the endoscopes provided in the embodiments of the present application, the first circuit board 200 can be a flexible plate, and has a mounting surface. The first circuit board is bent so that the mounting surface faces outward of the working end of the endoscope, and the front-end functional module 100 is electrically connected with the first circuit board 200 on the mounting surface.

[0064] It should be understood that, by configuring the first circuit board 200 as a flexible plate inside the endoscope, the mounting surface can be made to face outward of the working end of the endoscope by bending, and the front-end functional module 100 is electrically connected with the first circuit board 200 at the mounting surface, in this structural layout, the mounting surface where the front-end functional module 100 is located is not in the radial direction of the endoscope, but can be configured to be oriented in the axial direction of the endoscope, so that the front-end functional module 100 can be arranged along the extension direction of the first circuit board 200 to make full use of the sufficient mounting space of the endoscope in the extension direction, thereby optimizing the structural layout of the first circuit board 200 and the front-end functional module 100 and improving the overall structural compactness of the endoscope while ensuring reliable electrical connection of the front-end functional module 100.

[0065] In an optional solution, as shown in Figure 2 、 Figure 6 、 Figure 10 and Figure 12 , the first circuit board 200 includes a plate body 210, the plate body 210 includes a second sub-plate 211 at the first end thereof, the first end of the plate body 210 extends to the working end of the endoscope, and the front-end functional module 100 is arranged on the second sub-plate 211; the front-end functional module 100 includes a camera 110 and a light source, and the first circuit board 200 bends the second sub-plate 211 so that the camera 110 and the light source are both oriented outward of the working end of the endoscope.

[0066] It should be understood that, in this embodiment, the mounting surface is located on the second sub-plate 211. By bending the second sub-plate 211, the structural form of the plate body 210 can be changed, and in another aspect, this embodiment is equivalent to bending the second sub-plate 211 relative to the extension direction of the plate body 210, so that the orientation of the camera 110 and the light source arranged on the second sub-plate 211 can be changed, so that the camera 110 and the light source are oriented outward of the working end of the endoscope to facilitate image acquisition and illumination.

[0067] Of course, the specific arrangement position of the mounting surface is not limited in the embodiments of the present application, for example, it can also be arranged on the first sub-plate 220 in the foregoing embodiments, or other sub-structures of the first circuit board 200.

[0068] Further, as shown in Figure 12As shown, the number of light sources can be two, including the first light source 120 and the second light source 130, the second sub-plate 211 includes the first branch 211a and the second branch 211b which are symmetrically arranged along the extension direction of the plate body 210, the camera 110 is arranged between the first branch 211a and the second branch 211b, the first light source 120 is arranged on the first branch 211a, and the second light source 130 is arranged on the second branch 211b; the first branch 211a is bent towards the camera 110 so that the first light source 120 is arranged adjacent to the camera 110, and the second branch 211b is bent towards the camera 110 so that the second light source 130 is arranged adjacent to the camera 110.

[0069] In this structural layout, the first branch 211a and the second branch 211b are symmetric to each other, so that the first light source 120 and the second light source 130 are symmetric to each other, and the symmetric structure helps to optimize the structural layout inside the endoscope and improve the structural compactness. At the same time, the first light source 120 and the second light source 130 are arranged adjacent to the camera 110, so as to ensure that the viewing area of the camera 110 has a high brightness, thereby optimizing the viewing effect of the camera 110. In addition, the first light source 120 and the second light source 130 are symmetrically arranged on both sides of the camera 110, so as to balance the light brightness in the viewing area of the camera 110.

[0070] Further, as shown, Figure 12 The endoscope includes an inner tube body 400, the inner wall of the inner tube body 400 is provided with a first avoiding groove 420 and a second avoiding groove 430, part of the first branch 211a is bent away from the camera 110 so that the first light source 120 is located in the first avoiding groove 420, and part of the second branch 211b is bent away from the camera 110 so that the second light source 130 is located in the second avoiding groove 430.

[0071] In this structural layout, the first branch 211a is bent so as to ensure that the first light source 120 is directed out of the working end of the endoscope, and the second branch 211b is bent so as to ensure that the second light source 130 is directed out of the working end of the endoscope; the first avoiding groove 420 provides a containing space for the first light source 120 and part of the first branch 211a, and the second avoiding groove 430 provides a containing space for the second light source 130 and part of the second branch 211b, thereby improving the structural compactness inside the endoscope.

[0072] In an optional scheme, the first electrostatic flow guide 300 is a plate-shaped structural member, and one side of the plate face of the first electrostatic flow guide 300 is arranged opposite to the front-end functional module 100. In this arrangement, the plate-shaped first electrostatic flow guide 300 has a larger plate face area, thereby improving the electrostatic absorption effect.

[0073] In an optional solution, the first electrostatic flow member 300 is made of copper. Copper has a good electrostatic absorption effect. Of course, the first electrostatic flow member 300 can also be made of other materials such as aluminum.

[0074] In an optional solution, the outer surface of the first circuit board 200 is provided with a shielding film, which is arranged to avoid the front-end functional module 100 and the first electrostatic flow member 300. In this way, the shielding film can first prevent the signals transmitted on the first circuit board 200 from being disturbed, and at the same time, the shielding film is grounded, which can also achieve rapid discharge of static electricity through space coupling, thereby further reducing the negative effects of static electricity interference inside the endoscope.

[0075] In an optional solution, as shown in Figure 2 In the bending area of the first circuit board 200, at least part of the bending area is provided with a bending slot 203 arranged along the extension direction thereof. It should be understood that the bending slot 203 is a linear hollow area on the first circuit board 200, which is arranged on the extension path of the bending area, thereby improving the convenience of bending the first circuit board 200, that is, reducing the bending difficulty.

[0076] As shown in Figure 13 Based on the foregoing endoscope, the embodiment of the present application also provides an endoscope assembly, which comprises a controller 500 and the endoscope according to any one of the foregoing solutions. Thus, the endoscope assembly of the embodiment of the present application has the beneficial effects of any one of the foregoing endoscope solutions, which will not be described here.

[0077] The endoscope is electrically connected to the controller 500 at the operating end thereof, and the controller 500 can issue control instructions to the endoscope. Usually, the second end of the first circuit board 200 can be provided with a gold finger, and the endoscope can be electrically connected to the controller 500 through the gold finger.

[0078] Specifically, the controller 500 comprises a second circuit board 510 arranged inside the controller 500, and the first circuit board 200 is electrically connected to the second circuit board 510 through the gold finger at the second end thereof, so as to realize the connection between the endoscope and the controller 500. In addition, the controller 500 can also comprise a touch panel 520, which is a control and interaction member of the controller 500, and is connected to the second circuit board 510, used to issue operation instructions through actions such as pressing, clicking, and pointing on the touch panel 520, so as to realize control and interaction. The control and interaction principle of the touch panel 520 has many kinds, such as capacitive touch design and resistive touch design.
