Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an easily exposed vaginal dilator. Background Technology

[0002] During gynecological examinations or procedures, a vaginal speculum needs to be inserted into the patient's vagina to open the entire vagina, expose the cervix, and adjust its direction to facilitate the doctor's observation of the vaginal wall and cervix.

[0003] Current vaginal speculum is shaped like a two-lobed duckbill and has a fixed length. If the vagina is too deep or the cervix is ​​excessively tilted forward or backward, it is not easy to expose the cervix.

[0004] Therefore, this application proposes a vaginal dilator that is adjustable in length and easily exposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an easily accessible vaginal speculum, solving the problem of obstructed vision and impaired observation when encountering patients with excessively deep vaginas or excessively anteverted or retroverted cervixes.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an easily exposed vaginal speculum, comprising an upper leaf and a lower leaf, both of which are arc-shaped and have their inner arcs facing each other. The upper leaf and the lower leaf are rotatably connected to each other at their rear ends. The outer arc surfaces of the upper leaf and the lower leaf are slidably connected with outer layers, and the shapes of the two outer layers are respectively matched with the upper leaf and the lower leaf.

[0007] Preferably, the rear end of each of the outer layers is provided with a stalk that can pass through the upper or lower leaf, and the upper and lower leaves are provided with sleeves that cooperate with the stalk.

[0008] Preferably, the handle is provided with teeth, the sleeve is provided with a branch tube perpendicular to the length direction of the sleeve, a spring is connected inside the branch tube, and the other end of the spring is connected with a limiting tooth that cooperates with the teeth.

[0009] Preferably, a support piece is provided between the inner arc surfaces of the upper and lower blades to cover the gaps on both sides between the upper and lower blades.

[0010] Preferably, the support sheet is made of an elastic material.

[0011] Preferably, both support plates are riveted between the inner arc surfaces of the upper and lower blades.

[0012] Preferably, it also includes a rubber sleeve that can be fitted onto the outer surface of the upper and lower blades.

[0013] Preferably, the rubber sleeve is fixedly fitted onto the outside of the two outer layers.

[0014] Compared with the prior art, this utility model provides an easily exposed vaginal speculum, which has the following beneficial effects: This easily exposed vaginal speculum features a simple structure that allows for adjustable length. When encountering patients with excessively deep vaginas or cervical tilts that are excessively anteverted or retroverted, it can better expose the entire cervix, preventing obstruction of the doctor's view and thus affecting observation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please see Figure 1 The present invention provides the following technical solution: an easily exposed vaginal speculum, comprising an upper leaf 1 and a lower leaf 2, both of which are arc-shaped and have their inner arcs facing each other. The upper leaf 1 and the lower leaf 2 are rotatably connected to each other at the rear end. The outer arc surfaces of the upper leaf 1 and the lower leaf 2 are slidably connected with an outer layer 3, and the shapes of the two outer layers 3 are respectively matched with the upper leaf 1 and the lower leaf 2.

[0019] As an optional implementation of this utility model, when encountering patients with excessively deep vaginas or excessively anteverted or retroverted cervixes, the outer layer 3 can be slid to extend the length of the entire dilator in order to expose the entire cervix and avoid obstructing the doctor's view, thus affecting observation.

[0020] The above structure allows for adjustable length of the dilator in a relatively simple way. When encountering patients with excessively deep vaginas or excessively anteverted or retroverted cervixes, it can better expose the entire cervix and avoid obstructing the doctor's view, thus affecting observation.

[0021] like Figure 2 As shown, the rear end of the outer layer 3 is provided with a handle 4 that can pass through the upper leaf 1 or the lower leaf 2, and the upper leaf 1 and the lower leaf 2 are provided with a sleeve 5 that cooperates with the handle 4.

[0022] As an optional embodiment of this utility model, the handle 4 can be easily held by the doctor to adjust the extension length of the outer layer 3. Therefore, the length of the dilator can be adjusted directly when the dilator is inserted into the patient's vagina, while avoiding contact with bacteria and affecting the patient's health.

[0023] like Figure 2-3 As shown, the handle 4 is provided with teeth 41, and the sleeve 5 is provided with a branch pipe 51 perpendicular to the length direction of the sleeve 5. A spring 52 is connected inside the branch pipe 51, and the other end of the spring 52 is connected to a limiting tooth 53 that cooperates with the teeth 41.

[0024] As an optional embodiment of this utility model, when adjusting the length of the expander, the push and pull of the handle 4 can cause the teeth 41 to pop out the limiting teeth 53, ensuring that the length adjustment of the expander can be carried out normally. At the same time, after the adjustment is completed, the elasticity of the spring 52 can cause the limiting teeth 53 to act naturally between the adjacent teeth 41, thereby restricting the free movement of the handle 4. The doctor does not need to manually maintain the overall length of the expander for observation, making it more convenient for the doctor to use this expander.

[0025] Example 2: Compared to Example 1, the difference is as follows: Figure 4 As shown, a support piece 6 is riveted between the inner arc surfaces of the upper blade 1 and the lower blade 2 to cover the gaps on both sides between the upper blade 1 and the lower blade 2. The support piece 6 is made of elastic material.

[0026] As an optional embodiment of this invention, for patients with vaginal laxity, after the speculum is opened, the vaginal mucosa may squeeze in between the two leaves, obstructing the view and affecting the doctor's observation. Therefore, the elastic support piece 6 provided between the upper leaf 1 and the lower leaf 2 can prevent the vaginal mucosa from squeezing in through the gap between the upper leaf 1 and the lower leaf 2, avoiding obstruction of the doctor's view and affecting observation. The support piece 6 can be made of latex.

[0027] Example 3: Compared to Example 1, the difference is as follows: Figure 5 As shown, it also includes a rubber sleeve 7 that is fixedly fitted onto the outside of the two outer layers 3.

[0028] As an optional embodiment of this utility model, the outer layer 3 is used in conjunction with the fixing sleeve, which makes it easier to observe deep inside the vagina.

[0029] The working principle and usage of this utility model are as follows: When encountering patients with excessively deep vaginas or excessively anteverted or retroverted cervixes, the outer layer 3 can be slid to extend the length of the entire dilator in order to expose the entire cervix and avoid obstructing the doctor's view, thus affecting observation.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
