[0023] The utility model is further described below in conjunction with the accompanying drawings:
[0024] The directions described in the utility model specification, such as "up", "down", "left", "right", "front", "back", etc., are based on the directions of the drawings and are intended to facilitate the description of the relationship between the various components. They do not indicate the unique or absolute positional relationship between the various components. They are only one of the implementation methods of the utility model and are not a limitation on its implementation method.
[0025] like Figure 1 and Figure 2 As shown, a vaginal dilator includes a first clamp 1, a second clamp 2, a third clamp 3 and a fourth clamp 4, the heads of the first clamp 1, the second clamp 2, the third clamp 3 and the fourth clamp 4 are respectively provided with a first clamp 11, a second clamp 21, a third clamp 31 and a fourth clamp 41 extending forward, the tail of the first clamp 1 is provided with a handle 12 extending downward for a person to hold, the tail of the first clamp 1 is rotatably connected with the tail of the second clamp 2 so that the two can be opened and closed horizontally, a first adjusting structure 5 that can push the first clamp 1 and the second clamp 2 to open is provided between the first clamp 1 and the second clamp 2, the tail of the first clamp 1 is rotatably connected with the tail of the third clamp 3 so that the two can be opened and closed vertically, a second adjusting structure 6 that can push the first clamp 1 and the third clamp 3 to open is provided between the first clamp 1 and the third clamp 3, the tail of the second clamp 2 is rotatably connected with the tail of the fourth clamp 4 so that the two can be opened and closed vertically, and a third adjusting structure 7 that can push the second clamp 2 and the fourth clamp 4 to open is provided between the second clamp 2 and the fourth clamp 4, as shown in FIG. Figure 1As shown, the first clip 11, the second clip 21, the third clip 31, and the fourth clip 41 form a cylindrical shape when they are closed. Preferably, the head of the first clip 11, the head of the second clip 21, the head of the fourth clip 31, and the head of the fourth clip 31 are all designed to be duckbill-shaped, so that when the four clips are closed, they can be inserted into the vagina more easily and smoothly. After the four clips are inserted into the vagina, the first clamp 1 and the second clamp 2 can be adjusted by the first adjustment structure 5 to open and close, so that the first clamp 11 and the second clamp 21 can expand each other. Similarly, the first adjustment structure 5 can also be used to adjust the opening and closing of the first clamp 1 and the second clamp 21. The second adjustment structure 6 adjusts the opening and closing of the first clamp 1 and the third clamp 3, so that the first clamp 11 and the third clamp 31 expand with each other. The third adjustment structure 7 adjusts the opening and closing of the second clamp 2 and the fourth clamp 4, so that the second clamp 21 and the fourth clamp 41 expand with each other. Then, the gap between any two of the first clamp 11, the second clamp 21, the third clamp 31, and the fourth clamp 41 can be used for observation and application of medicine, and the expansion of any two adjacent clamps can be flexibly controlled, which is convenient for observing different positions on the inner wall of the vagina and applying medicine at different positions.
[0026] In detail, Figure 4 As shown, the handle 12 on the first clamp 1 is provided with an axial hole 13, and the second clamp 2 is provided with a rotating shaft 22 passing through the axial hole 13, so that the first clamp 1 and the second clamp 2 are rotatably connected.
[0027] As a preferred implementation of the first adjustment structure 5, Figure 4 and Figure 5 As shown, the first adjustment structure 5 includes a spring piece 51 arranged on the handle 12, a ratchet 52 arranged on the rotating shaft 22 and coaxial with the rotating shaft 22, and a button 53 slidably connected to the handle 12, wherein the spring piece 51 has a pawl piece 511 extending toward the ratchet 52 and capable of being stuck on the ratchet teeth of the ratchet 52, the pawl piece 511 is connected to a pressing piece 512, and one end of the button 53 abuts against the pressing piece 512. When in use, the button 53 is first pressed, thereby causing the ratchet to be engaged. The claw piece 511 is pressed and disengaged from the ratchet teeth. At this time, the first clamp 1 and the second clamp 2 can be opened by rotating the rotating shaft 22. After opening to a certain angle, the button 53 is released. At this time, the first clamp 1 and the second clamp 2 maintain the angle. When the first clamp 1 and the second clamp 2 need to be closed, only the button 53 needs to be pressed. Due to the contraction force of the inner wall of the vagina, the first clamp 1 and the second clamp 2 can be closed, thereby adjusting the opening and closing of the first clamp 1 and the second clamp 2. As a preferred embodiment, Figure 1 and Figure 4 As shown, the lower end of the rotating shaft 22 extends out from the bottom of the handle 12 , and a knob 23 for a person to hold can be provided at the lower end of the rotating shaft 22 , so that the rotating shaft 22 can be rotated by manually holding the knob 23 .
[0028] As a preferred implementation of the first adjustment structure 5, Figure 1 and Figure 3 As shown, the second adjustment structure 6 includes a first adjustment rod 61 rotatably connected to the tail of the first clamp 1, and a first adjustment hole 62 arranged at the tail of the third clamp 3 and used for the first adjustment rod 61 to pass through. The tail of the third clamp 3 is provided with a first auxiliary handle 32 that extends obliquely downward. The first adjustment hole 62 is arranged on the first auxiliary handle 32. The first adjustment rod 61 is threadedly connected with a first nut member 63. When the first nut member 63 is adjusted to be screwed in toward the first clamp 1, the first nut member 63 can abut against the third clamp 3. The first nut member 63 is threadedly connected to the first adjustment rod 61. By rotating the first nut member 63, the first nut member 63 can be axially moved on the first adjustment rod 61. By screwing in the first nut member 63, the first nut member 63 is pressed against the first auxiliary handle 32, thereby making the first clamp 1 and the third clamp 3 open to each other.
[0029] Similarly, if Figure 1 As shown, the third adjustment structure 7 adopts the same structure as the second adjustment structure 6, and the third adjustment structure 7 includes a second adjustment rod 71 rotatably connected to the tail of the second clamp 2, and a second adjustment hole 72 arranged at the tail of the fourth clamp 4 and used for the second adjustment rod 71 to pass through. The tail of the fourth clamp 4 is provided with a second auxiliary handle 42 extending obliquely downward, and the second adjustment hole 72 is arranged on the second auxiliary handle 42. The second adjustment rod 71 is threadedly connected with an adjustment second nut member 73. When the adjustment second nut member 73 is screwed in toward the second clamp 2, the second nut member 73 can abut against the fourth clamp 4. The principle is the same as that of the second adjustment structure 6.
[0030] As a preference, Figure 1 and Figure 2 As shown, the upper end of the tail of the third clamp 3 is provided with a first notch 33, and the upper end of the tail of the fourth clamp 4 is provided with a second notch 43. When the third clamp 3 and the fourth clamp 4 are closed, the first notch 33 and the second notch 43 are combined to form a semicircular notch to increase the observation space and the operation space for applying the medicine.
[0031] As a more optimal solution, the first clamping piece 11, the second clamping piece 21, the third clamping piece 31 and the fourth clamping piece 41 are all provided with hollow windows a to facilitate the drug application operation.
[0032] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
