[0025] Embodiment

[0026] As Figures 1-5 shown, an adjustable vaginal dilator proposed by the present utility model includes a first dilating piece 1, a second dilating piece 2, and a holding handle 3. The first dilating piece 1 and the second dilating piece 2 are rotatably connected. One end of the second dilating piece 2 is fixedly connected to one end of the holding handle 3. It further includes: a plug rod 31 provided on the holding handle 3. A clamping block 33 for clamping the adjusting handle 4 is fixedly connected to the end of the plug rod 31 away from the holding handle 3. A plurality of pairs of linearly arranged tooth grooves 34 are provided on the plug rod 31. The shape of the tooth grooves 34 is to clamp the clamping plate 42 to move towards the clamping block 33. When the clamping plate 42 moves towards the holding handle 3, at this time, the clamping plate 42 will automatically open and make it easy for the adjusting handle 4 to move towards the holding handle 3; an adjusting handle 4 fixedly connected to one end of the first dilating piece 1. A first sliding hole 41 for the plug rod 31 to movably penetrate is opened on the adjusting handle 4. An adjusting mechanism for fixing the opening angle between the first dilating piece 1 and the second dilating piece 2 is provided on the surface of the adjusting handle 4 close to the holding handle 3; a second sliding hole 5 opened on the adjusting handle 4 and on the same axis as the first sliding hole 41. A pushing mechanism for pressing against the adjusting mechanism to start it is provided inside the second sliding hole 5.

[0027] Furthermore, the adjusting mechanism includes a pair of clamping plates 42 provided on the adjusting handle 4 on both sides of the first sliding hole 41. The clamping plates 42 are used to clamp the adjusting handle 4 to move away from the holding handle 3 through the telescopic slots 43, and the clamping plates 42 make the adjusting handle 4 automatically move towards the holding handle 3 after being pressed through the telescopic slots 43. Telescopic slots 43 are opened on both clamping plates 42. T-shaped clamping blocks 44 that are fixedly connected to the adjusting handle 4 and are inserted into the telescopic slots 43 are provided on the adjusting handle 4. The T-shaped clamping blocks 44 can both support the operation of the pushing spring 45 and clamp the clamping plates 42. A pushing spring 45 is provided inside the telescopic slot 43. The pushing spring 45 makes the clamping plates 42 automatically snap into the tooth grooves 34. One end of the pushing spring 45 is fixedly connected to the inner wall of the telescopic slot 43, and the other end of the pushing spring 45 is fixedly connected to the T-shaped clamping block 44.

[0028] Among them, the pushing mechanism includes a sliding rod 51 slidably connected in the second sliding hole 5. One end of the sliding rod 51 is fixedly connected with a resisting block 53, and a pair of semi-circular attaching plates 54 for clamping the surrounding plate 46 are fixedly connected to the resisting block 53. The semi-circular attaching plates 54 can cause the clamping plate 42 with the surrounding plate 46 to tilt away from the adjusting handle 4. Both ends of the clamping plate 42 close to the resisting block 53 are fixedly connected with the surrounding plate 46 that moves and opens after being resisted by the resisting block 53.

[0029] Secondly, the end of the sliding rod 51 away from the resisting block 53 is fixedly connected with a pushing block 52. A plurality of anti-slip strips arranged linearly are provided on the surface of the pushing block 52 away from the sliding rod 51. The function of the anti-slip strips is to increase the friction when the doctor manually pushes the pushing block 52 and prevent the pushing block 52 from sliding.

[0030] Furthermore, a return spring 32 is movably sleeved on the insertion rod 31. One end of the return spring 32 is fixedly connected with the holding handle 3, and the other end of the return spring 32 is fixedly connected with a spherical block that resists the clamping plate 42. The function of the spherical block is to prevent the other end of the return spring 32 from scratching the clamping plate 42.

[0031] In this embodiment, when the adjustable vaginal dilator needs to be used, as Figure 1 and Figure 2 shown, only one hand needs to hold the holding handle 3 and insert the closed ends of the first dilator blade 1 and the second dilator blade 2 into the vagina. Then, pinch the adjusting handle 4 in the direction of the holding handle 3. The adjusting handle 4 drives the first dilator blade 1 to open in the vagina, and then the opening angle between the first dilator blade 1 and the second dilator blade 2 can reach the required angle. At the same time, when the adjusting handle 4 moves towards the holding handle 3, the insertion rod 31 slides in the first sliding hole 41. When the opening angle between the first dilator blade 1 and the second dilator blade 2 stops, the clamping plate 42 is elastically pushed by the pushing spring 45, so that the clamping plate 42 is clamped into the tooth groove 34 on the insertion rod 31. Thus, it is avoided that the adjusting handle 4 moves away from the holding handle 3. Furthermore, only by stopping pressing the adjusting handle 4 in the direction of the holding handle 3, the opening angle between the first dilator blade 1 and the second dilator blade 2 can be fixed, which is simple and easy to operate.

[0032] When the opening angle between the first dilator blade 1 and the second dilator blade 2 is too large and needs to be adjusted smaller. Only need to push the pushing block 52 in the direction of the first sliding hole 41. The pushing block 52 drives the sliding rod 51 to slide in the second sliding hole 5. The end of the sliding rod 51 away from the pushing block 52 drives the resisting block 53 to resist the surrounding plate 46, so that the surrounding plate 46 drives the corresponding clamping plate 42 to disengage from the tooth groove 34 on the insertion rod 31. At this time, through the elastic thrust of the return spring 32 on the insertion rod 31, the adjusting handle 4 can drive the first dilator blade 1 to automatically move towards the second dilator blade 2 and close, so that the opening angle of the dilator in the vagina becomes smaller, which is convenient and fast.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to only the specific implementation manners. Obviously, according to the content of this specification, many modifications and variations can be made. These embodiments are selected and specifically described in this specification in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can well understand and utilize the present utility model. The present utility model is only limited by the claims and their full scope and equivalents.
