[0022] See also Figures 1 to 6 As shown, according to an embodiment of the present invention, a vaginal dilator is provided, comprising an outer cylinder body 1 and an inner cylinder body 2, wherein the outer cylinder body 1 comprises an outer sleeve 11 and a hand-holding portion 12 formed at the outer end of the outer sleeve 11, and the inner cylinder body 2 can be detachably inserted into a central through hole (not marked in the figure) of the outer sleeve 11 via the outer end of the outer sleeve 11, and the aforementioned outer end refers to the inside and outside of the vaginal dilator of the present invention relative to the examined human body when in use.

[0023] In this technical solution, after the dilator is inserted into the human vagina, its cylindrical outer sleeve 11 can form a stable and reliable support for the vaginal wall. This support process does not require manual force to open the mouth like the duckbill pliers in the prior art. That is, during the process of inserting the dilator of the present invention into the vagina and after insertion, the user does not need to control the force of opening the mouth. The user can just hold the aforementioned hand-held part 12 to control the forward and backward movement. No special training is required for use, and the operation is simple and convenient.

[0024] See Figure 2 As shown, the inner cylinder 2 in the present invention can be detachably inserted into the central through hole of the outer cylinder 1. During the insertion of the vaginal speculum, the inner cylinder 2 is assembled in the outer cylinder 1, and the two are inserted into the vagina simultaneously to ensure the smooth insertion of the vaginal speculum. When endoscopy, flushing and other operations are required, the inner cylinder 2 is pulled out from the central through hole, and the corresponding peep equipment and flushing equipment can enter the human body through the central through hole, which is very convenient.

[0025] See Figure 3As shown, in some embodiments, the outer cylinder body 1 includes a hard cylinder 101 and a soft cylinder 102 that is injection-molded and attached to the outside of the hard cylinder 101. The material of the soft cylinder 102 can be specifically silicone. In this technical solution, the soft cylinder 102 is injection-molded and attached to the outside of the hard cylinder 101. The soft cylinder 102 is made of soft materials, so that it has high skin-friendliness and good patient compliance. In a preferred embodiment, the hard cylinder 101 is injection-molded by hard glue PC, and the soft cylinder 102 is injection-molded by silicone, that is, the outer cylinder body 1 in the present invention is made by secondary molding. It can be used once, without disinfection and sterilization, which increases safety during use. It can be understood that in the process of injection molding the soft cylinder 102, the soft material can form a reliable bond with the hard cylinder 101 at the injection molding temperature.

[0026] In order to improve the bonding reliability between the soft tube 102 and the hard tube 101, an inverted structure (not shown in the figure) is provided between the soft tube 102 and the hard tube 101. It can be understood that the inverted structure is objectively formed by the soft material in liquid state entering into the groove structure formed at a local position on the outer wall surface of the hard tube 101 and solidifying.

[0027] In some embodiments, the outer contour of the soft tube 102 is similar to the shape of a male penis, which is comfortable to use and can be easily operated by doctors and patients without special training.

[0028] In some embodiments, the inner cylinder 2 includes a cylinder shell 21 and a soft layer 22 connected to the inner end surface of the cylinder shell 21. In a preferred embodiment, the soft layer 22 is made of silicone. When the inner cylinder 2 is inserted into the center through hole, the soft layer 22 protrudes from the inner end of the outer sleeve 11.

[0029] In this technical solution, by providing a soft layer 22 on the inner end of the tube shell 21, it is possible to prevent possible damage to the vagina during the insertion of the vaginal dilator, while improving the comfort of the vaginal dilator during the insertion process, and the patient has a better experience.

[0030] In some embodiments, the soft layer 22 is injection-molded onto the inner end surface of the cylindrical shell 21 , which can ensure the connection reliability between the soft layer 22 and the cylindrical shell 21 .

[0031] In some embodiments, staggered patterns are formed on the outer surface of the soft layer 22. The staggered patterns can be specifically realized by using a plurality of intersecting grooves, similar to a leather-like surface, so that the paste medicine can be easily and evenly attached to the surface, allowing doctors or patients (by themselves) to apply the medicine conveniently when using it.

[0032] In some embodiments, the vaginal dilator also includes a lighting assembly 3, and the lighting assembly 3 includes a lighting lamp 31. The lighting lamp 31 can illuminate the area corresponding to the inner end of the outer sleeve 11 when the inner cylinder 2 is moved out of the outer sleeve 11. During use, the problem of dim vision can be solved without additional lighting, further facilitating treatment.

[0033] The aforementioned lighting lamp 31 can specifically be an LED lamp bead, which has low power consumption and high brightness.

[0034] See Figure 6 As shown, the lighting assembly 3 also includes a battery mounting seat 32 and a lighting lamp mounting seat 34. The battery (specifically a button battery) is assembled on the battery mounting seat 32, and the lighting lamp 31 is installed on the lighting lamp mounting seat 34. The battery mounting seat 32 and the lighting lamp mounting seat 34 are interlocked with each other, and a conductive spring sheet 33 is clamped therebetween. The conductive spring sheet 33 realizes the electrical connection between the battery and the lighting lamp 31. When the lighting assembly 3 is not in use (not lighting), an insulating sheet is inserted between the conductive spring sheet 33 and the battery. When in use, the insulating sheet can be manually pulled out. The lighting assembly 3 also includes a back cover 35. The aforementioned battery mounting seat 32 and the lighting lamp mounting seat 34 are buckled together with the back cover 35 as a whole, so that they can be further detachably connected with the aforementioned hand-held portion 12 (such as a snap connection). It is worth emphasizing that the aforementioned back cover 35 can, on the one hand, shield the internal components of the lighting assembly 3, thereby enhancing the aesthetic appearance of the vaginal dilator. On the other hand, the thickness of the back cover 35 can be used to increase the thickness of the hand-held portion 12, thereby improving the user's hand-holding stability.

[0035] In a specific embodiment, the illuminating lamp 31 is arranged at the head position of the illuminating lamp mounting base 34, and the aforementioned battery is specifically a button battery (two 1.5V). In this way, the lighting demand can be met without an external power supply, and the use is simple and convenient.

[0036] In some embodiments, the wall of the central through hole is formed with a reflective layer, which can reflect the light emitted by the illuminating lamp 31, thereby making the inside of the vagina brighter during use. The aforementioned reflective layer can be achieved by polishing the wall of the central through hole. Of course, in some other feasible methods, it can also be achieved by separately laying a corresponding reflective film.

[0037] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention, and these improvements and variations should also be regarded as the protection scope of the present invention.
