[0043] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with 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 are within the protection scope of the present application.

[0044] The directional terms used in the following embodiments, such as up, down, left, right, front, or back, are merely for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the invention. Furthermore, the term "connection" herein includes any direct and indirect electrical or structural connection means. Therefore, if the text describes a first device connected to a second device, 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.

[0045] Please see Figure 1 , Figure 1 This is a schematic diagram of the external appearance of the endoscope device 1 according to the first embodiment of the present invention. Figure 1 As shown, the endoscopic device 1 includes an endoscopic image acquisition component 11, an insertion tube 12, and an operating handle 13. The endoscopic image acquisition component 11 is used to acquire images inside the patient's body. The operating handle 13 is for the operator to grip and provides a controller for at least controlling the endoscopic image acquisition component 11. The insertion tube 12 is connected between the operating handle 13 and the endoscopic image acquisition component 11. During operation, the insertion tube 12 is inserted into the patient's body so that the endoscopic image acquisition component 11 can acquire images of organs or tissues 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, and its design depends on actual needs.

[0046] Please see Figures 1 to 5 , Figure 2 and Figure 3 This is a partial structural diagram of the endoscopic image acquisition component 11 from different angles according to the first embodiment of the present invention. Figure 4 and Figure 5 This is an exploded view of some components of the endoscopic image acquisition component 11 from different perspectives according to the first embodiment of the present invention. Figures 1 to 5 As shown, the endoscope image acquisition assembly 11 is located at the end of the insertion tube 12 away from the operating handle 13 and includes an image sensor 111, a circuit board 112, a lens assembly 113, a mounting base 114, and a housing 115.

[0047] An image sensor 111, a circuit board 112, a lens group 113, and a mounting base 114 are disposed within a housing 115. The circuit board 112 can be electrically connected to the controller of the operating handle 13 via at least one cable (not shown in the figure). The mounting base 114 is used to position the lens group 113 and includes a base body 1141 and four first terminals 1142. The base body 1141 forms an accommodating space 1143. The four first terminals 1142 are disposed on the base body 1141. The lens group 113 is engaged with the base body 1141 and can be a fixed-focus lens group or a zoom lens group that can magnify or reduce the image. The image sensor 111 is disposed within the accommodating space 1143 and can be a complementary metal-oxide-semiconductor (CMOS) sensor. The image sensor 111 includes four second terminals 1111 that are respectively electrically connected to the four first terminals 1142.

[0048] The circuit board 112 includes a board body 1121 and four third terminals 1122. The board body 1121 is vertical and fixed to the base 1141. The four third terminals 1122 are disposed on the board body 1121 and are electrically connected to the four first terminals 1142 respectively, so that the four second terminals 1111 can be electrically connected to the four third terminals 1122 respectively through the four first terminals 1142.

[0049] However, the number of the first terminal, second terminal, and third terminal of the present invention is not limited to this embodiment. For example, in another embodiment, the endoscopic image acquisition component may include only two first terminals, two second terminals, and two third terminals.

[0050] In addition, such as Figures 2 to 4 As shown, the image capturing component 11 further includes a passive electronic component 116 (e.g., a capacitor or resistor) disposed on one side of the circuit board 112.

[0051] However, the present invention is not limited thereto. For example, in another embodiment, the image capturing component may not include passive electronic components, or may include two passive electronic components disposed on the same side of the circuit board or on opposite sides of the circuit board.

[0052] Specifically, such as Figures 2 to 5As shown, the lens group 113 is fixedly engaged with the first side 1141A of the base 1141. The accommodating space 1143 is formed on the second side 1141B of the base 1141, which is away from the lens group 113 and adjacent to the plate 1121. When the image sensor 111 is disposed in the accommodating space 1143, the image sensor 111 is located between the base 1141 and the plate 1121. The plate 1121 has a notch structure 1123. The base 1141 is engaged with the notch structure 1123. Each third terminal 1122 is adjacent to the outer edge of the notch structure 1123. The optical axis of the lens group 113 is perpendicular to the opening of the accommodating space 1143 and parallel to the circuit board 112. That is, the extension direction of the lens group 113 is parallel to the normal direction of the second side 1141B of the base 1141 and perpendicular to the normal direction of the plate 1121 of the circuit board 112.

[0053] Each first terminal 1142 includes a first portion 1142A and a second portion 1142B electrically connected to the first portion 1142A. Each first portion 1142A is disposed on the wall of the base 1141 adjacent to the accommodating space 1143 and electrically connected to the corresponding second terminal 1111. Each second portion 1142B is disposed on the wall of the base 1141 adjacent to the outer edge of the notch structure 1123 and electrically connected to the corresponding third terminal 1122.

[0054] More specifically, such as Figures 2 to 5 As shown, the second portions 1142B of two of the four first terminals 1142 are located on the first side 1141C of the base 1141 and are spaced apart and aligned with each other in a vertical direction perpendicular to the circuit board 112, while the second portions 1142B of the other two of the four first terminals 1142 are located on the second side 1141D of the base 1141 and are spaced apart and aligned with each other in a vertical direction perpendicular to the circuit board 112.

[0055] The notch structure 1123 includes a first side portion 1123A and a second side portion 1123B located on opposite sides of the circuit board 112. When the base 1141 engages with the notch structure 1123, the first side portion 1123A is adjacent to the first side 1141C of the base 1141 and is located between two second portions 1142B on the first side 1141C; the second side portion 1123B is adjacent to the second side 1141D of the base 1141 and is located between two other second portions 1142B on the second side 1141D.

[0056] Furthermore, two of the four third terminals 1122 are respectively disposed on the top and bottom sides of the first side portion 1123A, and the other two of the four third terminals 1122 are respectively disposed on the top and bottom sides of the second side portion 1123B. The projections of the two third terminals 1122 located on the top sides of the first side portion 1123A and the second side portion 1123B overlap with the projections of the two third terminals 1122 located on the bottom sides of the first side portion 1123A and the second side portion 1123B in the vertical direction.

[0057] Each third terminal 1122 is perpendicular to the second portion 1142B of the corresponding first terminal 1142, and each third terminal 1122 can be fixed and electrically connected to the second portion 1142B of the corresponding first terminal 1142 by soldering via a solder structure (not shown in the figure). Each second terminal 1111 can be a solder ball and can be electrically connected to the first portion 1142A of the corresponding first terminal 1142 by wire bonding via a solder wire 1112, that is, each second terminal 1111 is electrically connected to the corresponding third terminal 1122 through the corresponding first terminal 1142.

[0058] However, the present invention is not limited to this embodiment. For example, in another embodiment, each second terminal may be a pin or contact and may be electrically connected to a first portion of the corresponding first terminal via a solder structure. Alternatively, in another embodiment, each third terminal may be electrically connected to a second portion of the corresponding first terminal via wire bonding.

[0059] The configuration of the first embodiment described above can save space, so the present invention has the advantages of compact structure and small size.

The spacing between the two second portions 1142B” aligned with each other along the direction perpendicular to the circuit board 112” is approximately equal to the thickness of the circuit board 112”. Two of the four third terminals 1122” are spaced apart from each other on the top side of the abutment portion 1121A”, and the other two of the four third terminals 1122” are spaced apart from each other on the bottom side of the abutment portion 1121A”.

Other structures in this embodiment are similar to those in the second embodiment and will not be described further for simplicity.

[0065] Please see Figures 14 to 17 , Figure 14 and Figure 15 This is a partial structural diagram of the endoscopic image acquisition component 11”' from different viewpoints according to the fourth embodiment of the present invention.
