Existing vaginal dilators are generally used under incandescent light sources, relying on the doctor's subjective experience and vision for examinations and surgeries. Due to the low resolution and strong subjectivity of the human eye, it is easy to cause missed or misdiagnosis, or deviations in surgical operations. Summary of the invention

[0003] The purpose of the present invention is to provide a vaginal dilator, which can be used to conveniently and clearly photograph the vagina after dilating the vagina. The present invention also provides a vaginal inspection system using the vaginal dilator.

[0004] The present invention discloses a vaginal dilator, which is used to be inserted into a vagina to dilate the vagina, and comprises a first dilating body and a second dilating body connected to each other, wherein the first dilating body and the second dilating body respectively comprise a first dilating plate and a second dilating plate inserted into the vagina during operation, wherein the first dilating plate and the second dilating plate are used to relatively rotate and / or relatively move during the dilating operation to dilate the vagina, and the vaginal dilator further comprises:

[0005] a light source, disposed on the second expansion body, for irradiating the inner wall of the vagina;

[0006] a first reflector, disposed on the inner side wall of the first expansion plate, for reflecting the light reflected from the inner wall of the vagina;

[0007] A second reflector, disposed on the inner side wall of the second expansion plate, for receiving and reflecting the light reflected by the first reflector;

[0008] The camera is arranged on the first expansion body, and when in operation, the lens faces the second reflector, and is used for receiving the light reflected by the second reflector and taking pictures.

[0009] In some embodiments, the camera is located at the rear end of the first expansion plate, the first reflector is located at the front side of the camera, the second reflector is located at the rear end of the second expansion plate, and the light beam emitted by the light source is emitted from the front side of the second reflector in a direction away from the second reflector.

[0010] In some embodiments, the first expansion body also includes a handle connected to the first expansion plate and an operation window provided on the handle, the axial direction of the camera intersects with the extension direction of the first expansion plate, and the end of the camera along the axial direction of the camera does not exceed the edge of the first expansion plate.

[0011] In some embodiments, the camera is detachably connected to the first expansion body.

[0012] In some embodiments, during operation, the first expansion plate is located above the second expansion plate, an insertion slot is provided on the first expansion plate, and the camera is inserted into the insertion slot to be installed on the first expansion plate.

[0013] In some embodiments, the insertion groove is a stepped groove that matches the outer contour shape of the camera.

[0014] In some embodiments, a control device for controlling the camera is also included, and the control device is wirelessly connected to the camera.

[0015] In some embodiments, one of the first expansion body and the second expansion body is provided with a slide groove, and the other one is provided with a slider that cooperates with the slide groove and is rotatably and slidably connected relative to the slide groove.

[0028] like Figures 1 to 4 As shown, the vaginal dilator of this embodiment is used to be inserted into the vagina to dilate the vagina.

[0029] The vaginal dilator comprises a first dilating body 1 and a second dilating body 2 which are connected to each other.

[0030] The first expansion body 1 includes a first expansion plate 11, and the second expansion body 2 includes a second expansion plate 21. The first expansion plate 11 and the second expansion plate 21 are inserted into the vagina when the vaginal dilator is working. When the expansion is performed, in some embodiments, the first expansion plate 11 and the second expansion plate 21 rotate relative to each other to expand the vagina, in some embodiments, the first expansion plate 11 and the second expansion plate 21 move relative to each other to expand the vagina, and in some embodiments, the first expansion plate 11 and the second expansion plate 21 move relative to each other and rotate relative to each other to expand the vagina. In the embodiment shown in the figure, the first expansion plate 11 and the second expansion plate 21 are duckbill-shaped expansion plates.

[0031] The vaginal dilator further includes a light source 4 , a first reflector 51 , a second reflector 52 and a camera 3 .

[0032] The light source 4 is disposed on the second expansion body 2, and the light source 4 is used to illuminate the inner wall of the vagina.

[0033] The first reflector 51 is disposed on the inner wall of the first expansion plate 11 , and is used to reflect the light reflected from the inner wall of the vagina.

[0034] The second reflector 52 is disposed on the inner wall of the second expansion plate 21 , and is used to receive and reflect the light reflected by the first reflector 51 .

[0035] The camera 3 is disposed on the first expansion body 1 , and when in operation, the lens faces the second reflector 52 . The camera 3 is used to receive the light reflected by the second reflector 52 and take pictures.

[0036] When working, the vaginal dilator is first inserted into the vagina, and then the relative movement and / or relative rotation of the first dilating plate 11 and the second dilating plate are operated to open the vagina. The light source 4 emits light to illuminate the inner wall of the vagina, and the first reflector 51 reflects the light reflected from the inner wall of the vagina to the second reflector 52, and the second reflector 52 reflects the light again to the camera 3, which receives the light and forms an image.

[0037] The vaginal dilator of this embodiment can illuminate and image the vagina more clearly by providing a camera 3 and a light source 4, thereby reducing direct observation by the human eye.

[0038] In addition, by separately arranging the light source 4 and the camera 3 on different expansion bodies, and by arranging the first reflector 51 and the second reflector 52 to help the camera 3 form an image, the position and angle of the light source 4 can be set more conveniently and flexibly. When the vaginal dilator is working, the light source 4 can be more conveniently in a suitable position and angle, and the light emitted by the light source 4 can be more or all directly irradiated on the inner wall of the vagina, reducing the irradiation of the inner wall of the vagina by diffuse reflection of the light through the inner wall of the first expansion plate 11 and the second expansion plate 21 of the vaginal dilator before the light source 4 irradiates the inner wall of the vagina. Since more light from the light source 4 directly irradiates the inner wall of the vagina, the light entering the camera 3 can be made more regular, reducing the interference caused to the camera 3 when shooting, and improving the imaging quality of the camera 3.

[0039] In some embodiments, the reflective surface shapes of the first reflector 51 and the second reflector 52 may be a plane, a quadratic surface, or a free-form surface, etc. The light emitted by the light source 4 includes white light and blue-green light.

[0040] In some embodiments, Figure 2As shown, the camera 3 is located at the rear end of the first expansion plate 11, the first reflector 51 is located at the front side of the camera 3, the second reflector 52 is located at the rear end of the second expansion plate 21, and the light beam emitted by the light source 4 is emitted from the front side of the second reflector 52 in a direction away from the second reflector 52.

[0041] The front and back of this application are based on the state of the vaginal dilator when it is inserted into the vagina. When inserted into the vagina, the direction in which the vaginal dilator goes deep into the vagina is the front. Relative to the front, the direction in which the vaginal dilator leaves the vagina is the back. This embodiment is precisely because the camera and the light source are set separately, and the first reflector 51 and the second reflector 52 are set at the same time, so that the positions and angles of the first reflector 51, the second reflector 52, the light source 4 and the camera 3 are arranged as follows: Figure 2 As shown, the light beam emitted by the light source 4 can be directly emitted from the front side of the second reflector 52 to the inner wall of the vagina, which avoids the light beam of the light source 4 from irradiating the second reflector 52 as much as possible, reduces the interference of the light beam on the second reflector 52, and at the same time, can also minimize the interference with the first reflector 51. The camera 3 receives the reflected light from the second reflector 52, and minimizes other light directly entering the camera 3, which greatly improves the image quality of the camera 3. In some embodiments, the light beam emitted by the light source 4 is approximately parallel to the first reflector 51.

[0042] In some embodiments, the light source 4 also includes a battery 41 and a battery switch 42 arranged on the second expansion body 2. The battery switch 42 is an elastic sheet switch. By pressing the battery switch 42, the opening and closing states of the battery switch 42 can be switched, so that the battery 41 can be turned on or off, and the light source 4 can be illuminated or turned off.

[0043] In some embodiments, Figure 1 , Figure 2 and Figure 4 As shown, the first expansion body 1 also includes a handle 12 connected to the first expansion plate 11 and an operation window 13 provided on the handle 12. The axial direction of the camera 3 intersects with the extension direction of the first expansion plate 11, and the end of the camera 3 along the axial direction of the camera 3 does not exceed the edge of the first expansion plate 11. The operation window 13 is a cavity structure. During operation, personnel can observe the internal conditions of the vagina through the operation window 13, and can also extend some operating equipment into the vagina through the operation window for operation. In this embodiment, the end edge of the camera 3 is set not to exceed the edge of the first expansion plate 11 along the axial direction, so as not to affect the operation of the operation window 13, and provide great space and convenience for personnel to perform medical operations through the operation window 13.

[0044] In some embodiments, Figure 1 and Figure 2As shown, the camera 3 is detachably connected to the first expansion body 1. The first expansion body 1 and the second expansion body 2 of this embodiment can be used as disposable items, and the camera 3 can be reused, and the camera 3 can be used again with the replaced first expansion body 1. This embodiment can improve the reuse rate of the product while ensuring medical hygiene.

[0045] In some embodiments, Figure 2 As shown, during operation, the first expansion plate 11 is located above the second expansion plate 21, and an insertion slot 111 is provided on the first expansion plate 11. The camera 3 is inserted into the insertion slot 111 to be installed on the first expansion plate 11. In this embodiment, the insertion slot 111 is provided on the first expansion plate 11 located above, and the camera 3 can be conveniently detachably connected to the first expansion body 1 by insertion, and is stably located in the insertion slot 111 under the action of gravity.

[0046] In some embodiments, Figure 2 As shown, the insertion groove 111 is a stepped groove that matches the outer contour shape of the camera 3. Figure 2 As shown, the outer contour of the camera 3 is stepped, and the insertion groove 111 is a stepped groove that matches the outer contour of the camera 3.

[0047] In some embodiments, the vaginal dilator further includes a control device for controlling the camera 3, and the control device is wirelessly connected to the camera 3. The control device is used to control the operation of the camera 3, such as adjusting the camera 3 to take pictures, adjust the focal length, the aperture size, etc. By wirelessly controlling the camera 3, interference to the camera 3 can be reduced, making the camera 3 more stable and improving the imaging quality.

[0048] In some embodiments, Figure 2 As shown, the camera 3 also includes a light barrier protection glass window 31, which is arranged on the outside of the lens group of the camera 3 and is fixed and assembled with the lens group by UV glue.
