[0031] This embodiment provides a gynecological vaginal dilator, such as Figures 1 to 3 As shown, it includes a lantern-shaped expansion component and an adjustment component, wherein:

[0032] The lantern-shaped expansion component includes a first connecting ring 11, a second connecting ring 12, a deformable connecting frame and a transparent outer film 14. The first connecting ring 11 and the second connecting ring 12 are parallel and coaxial. One end of the deformable connecting frame is connected to the first connecting ring 11, and the other end is connected to the second connecting ring 12. The transparent outer film 14 is wrapped outside the deformable connecting frame, and one end is sealed to the first connecting ring 11, and the other end is sealed to the second connecting ring 12. The adjustment component is evenly arranged between the first connecting ring 11 and the second connecting ring 12 in the circumferential direction.

[0033] The adjusting assembly includes a sleeve 21, an adjusting rod 22 and an adjusting nut 23 which are coaxially arranged with the lantern-shaped expansion assembly. The sleeve 21 is fixed at one end of the second connecting ring 12 away from the first connecting ring 11. The adjusting rod 22 penetrates the sleeve 21 and the lantern-shaped expansion assembly from the axis. The adjusting rod 22 is fixedly connected to the first connecting ring 11 and is slidingly connected to the second connecting ring 12 and cannot rotate relative to the second connecting ring 12. The adjusting nut 23 is arranged at one end of the sleeve 21 away from the second connecting ring 12. The adjusting nut 23 is threadedly connected to the adjusting rod 22. The adjusting nut 23 is rotatably connected to the sleeve 21. An injection channel 24 that penetrates the adjusting rod 22 is opened at the axial position of the adjusting rod 22.

[0034] Compared with the traditional upper and lower vaginal dilator structure, the lantern-shaped expansion component expands circumferentially as a whole, which overcomes the defect of the prior art that vaginal tissue will be squeezed in on both sides of the upper and lower vaginal dilators, so that the cervix cannot be fully exposed and is not conducive to observation. During the examination, at least a part of the lantern-shaped expansion component should be exposed at the vaginal opening, and cooperate with the transparent outer membrane 14 to facilitate the doctor to observe from the outside, and the contact area between the lantern-shaped expansion component and the vaginal wall is larger, which can effectively relieve the patient's discomfort during the examination and reduce the patient's psychological burden. The expansion degree of the lantern-shaped expansion component can be controlled by adjusting the component, and the expansion is carried out step by step, which can effectively relieve the patient's discomfort; in addition, by opening the injection channel 24 on the adjusting rod 22, the defect of the inconvenience of adding liquid medicine in the prior art can be overcome, and a dedicated channel is provided for the addition of liquid medicine, which is convenient for realizing immediate treatment after examination.

[0035] In this embodiment, a limiting member 223 is provided at the end of the adjusting rod 22 away from the first connecting ring 11, and the limiting member 223 is used to prevent the adjusting rod 22 and the adjusting nut 23 from loosening, and the injection channel 24 passes through the limiting member 223; the adjusting rod 22 is rotatably connected to the first connecting ring 11 through a first bearing, and the adjusting rod 22 includes a smooth portion 221 and a threaded portion 222, the threaded portion 222 is located at one end of the adjusting rod 22 close to the adjusting nut 23, and the smooth portion 221 is located at one end of the adjusting rod 22 close to the first adjusting ring, and the adjusting screw extends into the adjusting nut 23 and is rotatably connected to the sleeve 21 through a second bearing. After being set up in this way, when in use, first insert the first connecting ring 11 from the patient's vaginal opening, and after insertion, hold the sleeve 21 with one hand to keep it still, and rotate the adjusting nut 23 in the positive direction with the other hand. Since the adjusting nut 23 is rotationally connected with the sleeve 21, and the adjusting rod 22 is threadedly connected with the adjusting nut 23, when the adjusting nut 23 rotates forward, the adjusting rod 22 rotates outward, thereby driving the first connecting ring 11 to move toward the second connecting ring 12, so that the deformable skeleton is further compressed and expanded outward, and the transparent outer membrane 14 is stretched open to present a lantern shape for easy observation.

[0036] In this embodiment, the deformable skeleton includes 4 to 6 deformable connecting strips 13 that are evenly arranged around the adjusting rod 22. Each deformable connecting strip 13 is an arc-shaped strip convex outward. It should be noted that when the limit member 223 conflicts with the adjusting nut 23, the distance between the first connecting ring 11 and the second connecting ring 12 is the largest. At this time, the lantern is in a folded state. In the folded state, each deformable connecting strip 13 still presents a slightly convex shape, but the convex arc is smaller. The purpose of this arrangement is to ensure that the deformation direction of the deformable connecting strip 13 is correct when the first connecting ring 11 approaches the second connecting ring 12.

[0037] In this embodiment, the material of the deformable connecting strip 13 is preferably medical polyethylene, which has both certain elasticity and certain supporting capacity. The material of the transparent outer film 14 is preferably polyurethane or aerogel material, which can be thin, transparent, and elastic, meeting the design requirements of the lantern-shaped expansion component.

[0038] In this embodiment, a liquid distribution chamber 3 is fixedly provided on one side of the first connecting ring 11 away from the second connecting ring 12. The side of the liquid distribution chamber 3 away from the first connecting ring 11 is an arc surface, and a plurality of injection holes 31 are evenly arranged on the arc surface in a circumferential direction. An arc-shaped protrusion 32 facing the injection channel 24 is arranged at the top center position of the liquid distribution chamber 3. By setting up the liquid distribution chamber 3, the filling of the medicine liquid can be made more uniform. The material of the liquid distribution chamber 3 is preferably silicone or TPE, so that the surface of the liquid distribution chamber 3 can be smooth and have a certain elasticity. The end of the liquid distribution chamber 3 away from the first connecting ring 11 is the end that first extends into the patient's vaginal opening. Designing it as an arc surface can effectively alleviate the patient's discomfort.

[0039] In this embodiment, a plurality of auxiliary wrenches 231 are evenly arranged circumferentially on the side wall of the adjusting nut 23 . Such a design makes the operation of rotating the adjusting nut 23 more convenient.

[0040] In this embodiment, an injection port 242 is provided at one end of the injection channel 24 close to the limiter 223, and a pluggable plug 241 is provided on the injection port 242. When the liquid medicine does not need to be added, the plug 241 is used to block the injection port 242 to improve safety.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
