Technical Field
[0001] The utility model relates to a medical device, in particular to a light source side-mounted FPC module of an endoscope. Background Art
[0002] As we all know, an endoscope is a detection instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. It can enter the stomach through the mouth or other natural orifices into the body. The endoscope can be used to see lesions that cannot be displayed by X-rays, and it is widely used in the medical field.
[0003] The FPC module of an existing endoscope includes a support base, an FPC protruding laterally from the support base, a lens mounted forwardly on the support base, and an LED light mounted forwardly on the FPC. Because the FPC needs to be bent during the endoscope assembly process to accommodate the endoscope's smaller insertion portion, the bending of the FPC causes the LED light's light-emitting surface and the lens's imaging surface to face different directions. Furthermore, aligning the light-emitting and imaging surfaces by bending the FPC is extremely difficult.
[0004] Therefore, there is an urgent need for a side-mounted FPC module for an endoscope light source to overcome one or more of the above-mentioned defects. Utility Model Content

The light source is located outside the mounting portion and is fixedly connected to the mounting portion. When the light source is bent to the predetermined position following the first FPC, the light source is oriented in the same direction as the lens.

[0008] Preferably, the mounting portion is located at an end of the first FPC.
[0009] Preferably, the mounting portion is perpendicular to an end of the first FPC, and before the first FPC is bent, the orientation of the mounting portion is the same as or opposite to the orientation of the lens.
[0010] Preferably, the light source is mounted and fixed to the outer side surface of the mounting portion.
[0011] Preferably, there are two first FPCs arranged on opposite sides of the support base, and each first FPC corresponds to the light source.
[0012] Preferably, the two first FPCs arranged on opposite sides of the support seat are symmetrical to each other, the axis of the lens is located on the symmetry plane of the two first FPCs, and the lens is also staggered with the first FPC in the horizontal width direction of the first FPC.

The second FPC is arranged on the support seat adjacent to the first FPC, and the first FPC, the second FPC and the lens are electrically connected.
[0014] Preferably, the second FPC and the first FPC are both in a strip shape, and the horizontal width of the second FPC is greater than the horizontal width of the first FPC.
[0015] Preferably, the light source is an LED lamp, the shooting surface of the lens and the top surface of the support base are back to back to each other; and the first FPC is bent 90 degrees when switched to the preset position.

[0026] See also Figure 1 and Figure 3The light source side mounted FPC module 100 of the first embodiment includes a support base 10, a light source 20, a lens 40 supported by the support base 10, and a first FPC 50 protruding laterally from the support base 10. Figure 1 and Figure 3 As an example, the lens 40 is supported directly above the support base 10; obviously, according to actual needs, the position of the lens 40 on the support base 10 can also be other, so it is not used as an example. Figure 1 and Figure 3 Limits shown.
[0027] At the same time, the first FPC 50 is provided with a mounting portion 60 extending in the vertical direction of the support base 10, and the first FPC 50 can also be bent in the direction close to the lens 40 to Figure 3 The light source 20 is located outside the mounting portion 60 and is fixedly connected to the mounting portion 60. Optionally, as an example, the light source 20 is fixed to the outer side surface 61 of the mounting portion 60 by mounting, for example, by welding or gluing. The light source 20 is bent to the outside of the mounting portion 60 following the first FPC 50. Figure 3 The preset position shown is in the same direction as the lens 40, so that the shooting surface 41 of the lens 40 and the light emitting surface 21 of the light source 20 are in the same direction, so that the light source 20 provides a reliable lighting effect for the shooting of the lens 40. More specifically, as follows:
[0028] like Figure 1 and Figure 3 As shown in FIG. 1 , as an example, the shooting surface 41 of the lens 40 and the top surface 11 of the support base 10 are opposite to each other, so as to meet the need of arranging the shooting surface 41 of the lens 40 upward. In addition, the first FPC 50 is bent 90 degrees when switching to the preset position, so as to meet the need of arranging the first FPC 50 in a flat position before bending. Figure 3 In addition, when bending to Figure 3 When the preset position is shown, the position 52 of the first FPC 50 away from the mounting portion 60 is in close contact with the side surface 13 of the support base 10 (ie, close to and close to the side surface 13 of the support base 10). Figure 5 On the one hand, the support base 10 increases the support strength of the first FPC50, so that the light source 20 is more reliably suspended on the support base 10, for example but not limited to Figure 3 on the other hand, the first FPC 50 and the support base 10 are more compact, thereby making the light source side-mounted FPC module 100 of the first embodiment occupy a smaller space in the lateral direction.
[0029] like Figures 1 to 3 and Figure 5 As shown, as an example, the mounting portion 60 is located at the end 51 of the first FPC 50 to improve the utilization efficiency of the first FPC 50; Figure 1 、 Figure 3 and Figure 5 As an example, the mounting portion 60 is perpendicular to the end 51 of the first FPC 50, so that when the first FPC 50 is bent 90 degrees toward the direction close to the lens 40, the light emitting surface 21 of the light source 20 can be arranged upward. Figure 1 As an example, before the first FPC 50 is bent, the orientation of the mounting portion 60 is the same as that of the lens 40; this design allows the light source 20 to be closer to the lens 40 when following the first FPC 50 to be folded to the preset position, as shown in FIG. Figure 3 As shown, the gap between the light source 20 and the lens 40 is smaller, thereby effectively reducing the size of the light source side-mounted FPC module 100 of the first embodiment in the lateral direction (i.e., the direction parallel to the direction indicated by arrow A).
[0030] like Figures 1 to 5 As shown, as an example, the first FPC 50 is arranged on two opposite sides of the support base 10, and each first FPC 50 corresponds to a light source 20 to further increase the lighting effect; Figure 2 and Figure 4 As an example, the two first FPCs 50 arranged on opposite sides of the support base 10 are symmetrical to each other. The axis C1 of the lens 40 is located on the symmetry plane P of the two first FPCs 50. The lens 40 is also staggered relative to the first FPC 50 in the transverse direction of the first FPC 50 (see the direction indicated by arrow C and the opposite direction). This design is intended to prevent the lens 40 from being placed in the center between the two first FPCs 50. Specifically, as an example, the light source 20 is an LED lamp to achieve better energy saving. Obviously, according to actual needs, the light source 20 can also be other lamps, so this is not limited to this.
[0031] like Figures 1 to 5 As shown, as an example, the light source side-mounted FPC module 100 of the first embodiment also includes a second FPC70 for electrically connecting to an external PCB board. The second FPC70 is arranged on the support seat 10 at an adjacent edge to the first FPC50, and the first FPC50, the second FPC70 and the lens 40 are electrically connected; for example, as an example, the second FPC70 is electrically connected to the lens 40 and the first FPC50 respectively, so as to realize a way of electrically connecting the first FPC50, the second FPC70 and the lens 40, so as to facilitate the PCB board to control the lens 40 and the light source 20 with the help of the second FPC70. Specifically, as an example, the second FPC70 and the first FPC50 are both long strips, and the horizontal width W2 of the second FPC70 is larger than the horizontal width W1 of the first FPC50 to facilitate the bending operation of the first FPC50. It should be noted that, in Figure 1 and Figure 3In the example, the side where the second FPC 70 is located is the front side of the support base 10, and the side where the first FPC 50 is located is the left and right sides of the support base 50.
[0032] See also Figure 6 and Figure 7 The structure of the light source side-mounted FPC module 100 ′ of the second embodiment is substantially the same as that of the light source side-mounted FPC module 100 of the first embodiment, with the following differences:
[0033] In the light source side mounted FPC module 100' of the second embodiment, before the first FPC 50 is bent, the orientation of the mounting portion 60 is opposite to the orientation of the lens 40. In contrast, in the light source side mounted FPC module 100 of the first embodiment, before the first FPC 50 is bent, the orientation of the mounting portion 60 is the same as the orientation of the lens 40.
[0034] Therefore, after folding, the light source 20 in the light source side-mounted FPC module 100 of the first embodiment is closer to the lens 40 than the light source 20 in the light source side-mounted FPC module 100 ′ of the second embodiment.
[0035] Apart from the above differences, the other two are the same, so I will not go into details here.
[0036] Compared with the prior art, the first FPC 50 is provided with a mounting portion 60 extending in the vertical direction of the support base 10, and the light source 20 is located outside the mounting portion 60 and fixedly connected to the mounting portion 60. Figure 3 or Figure 7 When the preset position is set as shown, the light emitting surface 21 of the light source 20 and the shooting surface 41 of the lens 40 can be directed in the same direction, for example, toward Figure 3 and Figure 7 As shown above, the light emitting surface 21 of the light source 20 and the imaging surface 41 of the lens 40 are oriented toward the same direction, which facilitates operation.
[0037] It should be noted that the direction parallel to the direction indicated by arrow A is the lateral direction, which can also be regarded as the left and right direction of the support base 10, the direction indicated by arrow B is the direction from bottom to top of the support base 10, and the direction indicated by arrow C is the horizontal width direction of the first FPC50, which can also be regarded as the front and back direction of the support base 10.
[0038] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved. At the same time, what is disclosed above is only the preferred embodiment of the present invention, and of course it cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
