In order to ensure that the endoscope can smoothly enter the patient's body, the size of the wound cannot be further reduced, so there is still a need for improvement. SUMMARY

[0059] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. 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 the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0060] The directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only the directions of the attached drawings. Therefore, the directional terms used are used for illustration, not for limitation of the present application. In addition, the word "connected" herein includes any direct and indirect electrical or structural connection means. Therefore, if a first device is described as connected to a second device in the text, it means that the first device can be directly electrically / structurally connected to the second device, or indirectly electrically / structurally connected to the second device through other devices or connection means.

[0061] Please refer to Figure 1 , Figure 1 is a schematic view of the appearance of a scope 1 in the embodiments of the present application. As shown in Figure 1As shown, the endoscope 1 includes an image capturing component 11, an insertion tube 12, and an operating handle 13. The image capturing component 11 is used to capture images. The operating handle 13 is for the operator to hold and provides a controller for controlling the image capturing component 11. The insertion tube 12 is connected between the operating handle 13 and the image capturing component 11. The insertion tube 12 is inserted into the patient's body so that the image capturing component 11 can capture images inside the patient's body. Preferably, in this embodiment, the insertion tube 12 may be elastic or flexible; however, the invention is not limited to this embodiment.

[0062] Please refer to the following: Figures 2 to 7 , Figure 2 and Figure 3 These are exploded views of some components of the endoscope 1 according to an embodiment of the present invention from different perspectives. Figure 4 For example, in the implementation of this invention Figure 2 The diagram shown is an enlarged view of part of the structure of endoscope 1. Figure 5 For example, in the implementation of this invention Figure 3 The diagram shown is an enlarged view of part of the structure of endoscope 1. Figure 6 and Figure 7 This is a schematic diagram of the internal structure of the endoscope 1 in an embodiment of the present invention from different viewing angles. For example... Figures 2 to 7 As shown, the image capturing assembly 11 is located on the side of the insertion tube 12 away from the operating handle 13 and includes an image sensor 111 (e.g., a complementary metal-oxide-semiconductor (CMOS) image sensor), a first circuit board 112, a second circuit board 113, and a lens group 114.

[0063] In this embodiment, the image sensor 111 includes four electrical connectors 1111, the first circuit board 112 includes four first terminals 1121, the image sensor 111 is mounted on the first circuit board 112, and each electrical connector 1111 is electrically connected to a corresponding first terminal 1121. The second circuit board 113 includes four second terminals 1131, the second circuit board 113 is attached to and perpendicular to the first circuit board 112, and each second terminal 1131 is electrically connected to a corresponding first terminal 1121, so that each second terminal 1131 is electrically connected to a corresponding electrical connector 1111 through a corresponding first terminal 1121. The multiple electrical connectors 1111 of the image sensor 111 can be electrically connected to the multiple second terminals 1131 through the multiple first terminals 1121 respectively. The layout or arrangement of the multiple electrical connectors 1111 can be the same as or different from the layout or arrangement of the second terminals 1131, that is, the image sensor 111 can have different packaging structures. Therefore, the present invention has better adaptability and facilitates modularization. The lens group 114 is assembled on the image sensor 111 and can be a fixed-focus lens group or a zoom lens group that can magnify or reduce the image.

[0064] However, the number of electrical connectors, first terminals, and second terminals in this invention is not limited to this embodiment, and the number depends on actual needs. For example, in another embodiment, the image capturing component may only have one electrical connector, one first terminal, and one second terminal that are electrically connected to each other.

[0065] Specifically, each first terminal 1121 may include a first pad 1121A and a second pad 1121B. The first pad 1121A is exposed on the first side 1122 of the first circuit board 112, and the second pad 1121B is exposed on the second side 1123 opposite to the first side 1122. The first pad 1121A and the second pad 1121B are aligned with each other. The image sensor 111 may be a surface mount device (SMD) mounted on the first side 1122 of the first circuit board 112. Each electrical connector 1111 may be a solder ball structure, which is attached to the first pad 1121A of the corresponding first terminal 1121 by soldering to establish an electrical connection between the corresponding electrical connector 1111 and the corresponding first terminal 1121. Furthermore, each second terminal 1131 may include a third pad 1131A, with two of the four third pads 1131A exposed on the third side 1132 of the second circuit board 113, and the other two exposed on the fourth side 1133 of the second circuit board 113, the fourth side 1133 of the second circuit board 113 being opposite to the third side 1132 of the second circuit board 113. Each third pad 1131A and its corresponding second pad 1121B are not in direct contact with each other. Each third pad 1131A can be vertically attached and electrically connected to its corresponding second pad 1121B by soldering, thereby establishing an electrical connection between the corresponding second terminal 1131 and its corresponding first terminal 1121. In other words, the image capturing assembly 11 may further include four first soldering structures 115, each first soldering structure 115 being connected between the corresponding second pad 1121B and the corresponding third pad 1131A.

[0066] However, the present invention is not limited to this embodiment. For example, in another embodiment, the image capturing component may only have one electrical connector, one first terminal, and one second terminal. The first terminal may have a first pad and a second pad, which may be exposed on a first side and a second side of the first circuit board, respectively, but not aligned with each other. The second terminal may have a third pad exposed on one side of the second circuit board, and the third pad directly contacts the second pad. Alternatively, in another embodiment, the second pad of the first terminal and the third pad of the second terminal may be inclined to each other and attached to each other by soldering. Alternatively, in another embodiment, the image sensor may be a surface mount device with pins or contacts, and each first terminal may include a base for mating with pins or a contact for mating with contacts. Alternatively, in another embodiment, the image sensor may be a dual-in-line package (DIP) device with pins, and each first terminal may include a socket for mating with pins.

[0067] Furthermore, such as Figures 2 to 7 As shown, in this embodiment, the image capturing component 11 further includes five cables 116 that pass through the insertion tube 12 and are electrically connected to the circuit board of the second circuit board 113 and the controller circuit board of the operating handle 13 (not shown in the figure) to provide power and signal transmission between the second circuit board 113 and the controller circuit board of the operating handle 13.

[0068] In addition, in this embodiment, the second circuit board 113 further includes five third terminals 1134, each cable 116 is electrically connected to the corresponding third terminal 1134, and each second terminal 1131 is electrically connected to the corresponding third terminal 1134, so that each electrical connector 1111 is electrically connected to the corresponding cable 116 through the corresponding first terminal 1121, the corresponding second terminal 1131 and the corresponding third terminal 1134.

[0069] Specifically, each third terminal 1134 may include a fourth pad 1134A. Two of the five fourth pads 1134A may be exposed on the third side 1132 of the second circuit board 113, and the other three of the five fourth pads 1134A may be exposed on the fourth side 1133 of the second circuit board 113. Each second terminal 1131 may be electrically connected to the corresponding third terminal 1134 through a corresponding conductive element (e.g., solder wire or copper foil) to establish an electrical connection between the corresponding second terminal 1131 and the corresponding third terminal 1134. Each cable 116 may be attached to the fourth pad 1134A of the corresponding third terminal 1134 by soldering to establish an electrical connection between the corresponding cable 116 and the corresponding third terminal 1134. That is, the image capturing component 11 may further include five separate second soldering structures 117, and each second soldering structure 117 is connected between the corresponding cable 116 and the corresponding fourth pad 1134A.

[0070] However, the number and structure of the cable and the third terminal of the present invention are not limited to this embodiment, and their ends depend on actual needs. For example, in another embodiment, the image capturing component may include only one cable and one third terminal, and the third terminal has an insertion portion formed on it to allow cable insertion.

[0071] Please see Figures 2 to 9 , Figure 8 and Figure 9 These are schematic diagrams of the second circuit board 113 according to an embodiment of the present invention from different viewing angles. Figures 2 to 9 As shown, in this embodiment, the image capturing component 11 further includes a passive electronic component 118 (e.g., a capacitor or resistor) electrically connected to the second circuit board 113.

[0072] Specifically, the passive electronic component 118 may include two first mating terminals 1181, and the second circuit board 113 may include two first auxiliary terminals 1135. Each first auxiliary terminal 1135 may include a fifth pad 1135A, which is exposed on the fourth side of the second circuit board 113. Each first mating terminal 1181 may be soldered and electrically connected to the fifth pad 1135A of the corresponding first auxiliary terminal 1135 to establish an electrical connection between the corresponding first mating terminal 1181 and the corresponding first auxiliary terminal 1135. In other words, the image capturing component 11 may further include two third soldering structures (not shown in the figures), each third soldering structure being connected between the corresponding fifth pad 1135A and the corresponding first mating terminal 1181.

[0073] However, the present invention is not limited thereto. For example, in another embodiment, the second circuit board may include only a first auxiliary terminal having a fifth pad exposed on the third side of the second circuit board, and the passive electronic component may include only a first mating terminal attached to and electrically connected to the fifth pad. Alternatively, in another embodiment, the image capturing component may not include a passive electronic component or may include two passive electronic components located on the third and fourth sides of the second circuit board, respectively.

[0074] In addition, such as Figures 2 to 9 As shown, in this embodiment, the image capturing component 11 further includes a flexible auxiliary circuit board 119 and two light emitting components 11A. The two light emitting components 11A are disposed on the flexible auxiliary circuit board 119 and are used to emit light. The flexible auxiliary circuit board 119 is attached to and electrically connected to the second circuit board 113.

[0075] Specifically, the second circuit board 113 may include two second auxiliary terminals 1136, each second auxiliary terminal 1136 may include a sixth pad 1136A, the two sixth pads 1136A may be located on the two sides of the second circuit board 113 that are opposite to each other and adjacent to the third side 1132 and the fourth side 1133 respectively, the flexible auxiliary circuit board 119 may include two second mating terminals 1191, the two second mating terminals 1191 are electrically connected to the two light emitting components 11A respectively, each second mating terminal 1191 may include a seventh pad 1191A, each seventh pad 1191A may be vertically attached to the corresponding sixth pad 1136A by soldering, that is, the image capturing component 11 may further include two fourth soldering structures 11B, each fourth soldering structure 11B is connected to the corresponding sixth pad 1136A and the corresponding seventh pad 1191A.

[0076] However, the present invention is not limited to this embodiment. For example, in another embodiment, the image capturing component may include only a flexible auxiliary circuit board and a light emitting component. Alternatively, in another embodiment, the image capturing component may not include a flexible auxiliary circuit board or a light emitting component.

[0077] Please see Figure 2 , Figure 3 , Figure 6 , Figure 7 as well as Figure 10 , Figure 10 This is a partial structural side view of the endoscope 1 according to an embodiment of the present invention. (See image below.) Figure 2 , Figure 3 , Figure 6 , Figure 7 as well as Figure 10As shown, the image capturing assembly 11 further includes two light guiding assemblies 11C, a housing 11D, a window 11E, and a mounting base 11F. The two light guiding assemblies 11C are disposed in the housing 11D and are used to guide the light emitted by the two light emitting assemblies 11A respectively. The window 11E is disposed in the housing 11D and is used to protect the internal components (such as the lens group 114 and the two light guiding assemblies 11C) to prevent damage to the internal components. In addition, the window 11E includes an objective lens 11E1 and two light guides 11E2. The objective lens 11E1 is used to receive light from the observed object. The light can pass through the objective lens 11E1 and proceed toward the lens group 114. The two light guide mirrors 11E2 are respectively connected to the two light guiding components 11C and are respectively used to receive the light from the two light guiding components 11C. The light from the two light guiding components 11C can pass through the two light guide mirrors 11E2 and proceed toward the object being observed. The mounting base 11F is slidably mounted in the housing 11D so as to drive at least the first circuit board 112, the second circuit board 113, the image sensor 111, the lens group 114, the flexible auxiliary circuit board 119, and the two light emitting components 11A to slide together with the mounting base 11F.

[0078] Specifically, in this embodiment, the flexible auxiliary circuit board 119 may include a main body 1192 and two spring arms 1193 extending from the main body 1192. Each spring arm 1193 includes a spring-like structure, which is arranged in a direction parallel to the main body 1192 and can elastically deform in the same direction to generate an elastic force in the same direction. Two light emitting components 11A are respectively disposed on the two spring arms 1193. The mounting base 11F can be bonded to the two spring arms 1193 by an adhesive (e.g., UV glue). Each spring arm 1193 is used to drive the corresponding light emitting component 11A to abut against the corresponding light guiding component 11C. A support structure 11F1 is formed on the mounting base 11F. The flexible auxiliary circuit board 119 is located between the support structure 11F1 and the second circuit board 113 and abuts against the support structure 11F1 and the second circuit board 113.

[0079] However, the present invention is not limited to this embodiment. For example, in another embodiment, the mounting base may have multiple support structures, and the housing may have only one optical guiding component.

[0080] like Figure 2 , Figure 3 , Figure 6 , Figure 7 as well as Figure 10As shown, during the assembly of the image capturing assembly 11, the mounting base 11F can be pushed and slid into the housing 11D along the sliding direction D to push against the two spring arms 1193 of the flexible auxiliary circuit board 119. This causes the first circuit board 112, the second circuit board 113, the image sensor 111, the lens assembly 114, the flexible auxiliary circuit board 119, the two light emitting components 11A, and the five cables 116 to slide together until the two light emitting components 11A respectively abut against the two light guiding components 11C. Specifically, the spring-like structure of the two spring arms 1193 is used to provide elastic force along the sliding direction D during the assembly of the image capturing assembly 11. When the two light emitting components 11A respectively abut against the two light guiding components 11C, the two light emitting components 11A can be bonded to the two light guiding components 11C respectively by an adhesive (such as UV glue). Then, by pushing against the first circuit board 112, the second circuit board 113 or the cable 116, the lens group 114 can be driven to continue sliding along the sliding direction D and abut against the window 11E. During the sliding of the lens group 114 along the sliding direction D, since the main body 1192 of the flexible auxiliary circuit board 119 can slide together with the second circuit board 113 along the sliding direction D, the spring-like structure of the two elastic arms 1193 of the flexible auxiliary circuit board 119 can elastically deform and generate elastic force to drive the two light emitting components 11A to abut against the two light guiding components 11C respectively, thereby avoiding light leakage caused by the separation of the light guiding components 11C and the light emitting components 11A. When the lens group 114 comes into contact with the window 11E, the lens group 114 can be bonded to the window 11E by an adhesive (such as UV glue).

[0081] Furthermore, it is worth noting that the image capturing component 11 can also be applied to other image capturing devices (such as microscopes).

[0082] Compared to prior art, this invention utilizes a first circuit board to mount an image sensor, and establishes an electrical connection between the second terminal of the second circuit board and the electrical connector of the image sensor through the first circuit board and a second circuit board attached to and perpendicular to the first circuit board. The second terminal of the second circuit board is electrically connected to the first terminal of the first circuit board, and the first terminal of the first circuit board is electrically connected to the electrical connector of the image sensor, so that the second terminal is electrically connected to the electrical connector through the first terminal. This arrangement saves space, thus this invention has the advantages of compact structure and small size. Furthermore, when multiple electrical connectors, multiple first terminals, and multiple second terminals are present, the multiple electrical connectors of the image sensor can be electrically connected to the multiple second terminals through the multiple first terminals respectively. The layout or arrangement of the multiple electrical connectors can be the same as or different from the layout or arrangement of the second terminals, that is, the image sensor can have different packaging structures. Therefore, this invention has better adaptability and facilitates modularization.

[0083] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be included in the scope of the present invention.
