[0022] The present utility model provides a vaginal speculum. To make the purpose, technical solution and effect of the present utility model clearer and more definite, the following further describes the present utility model in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the present utility model.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, specific orientation structure and operation. Therefore, it cannot be understood as a limitation of the present utility model. In addition, "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is more than two.
[0024] Please refer to Figure 1 and Figure 2, the present utility model provides a vaginal speculum, which includes a handle and multiple sets of expansion components; the handle includes an upper handle 1 and a lower handle 2, and the upper handle 1 and the lower handle 2 are hinged; the expansion components include an upper insert 3 and a lower insert 4; the upper insert 3 is detachably connected to the upper handle 1; the lower insert 4 is detachably connected to the lower handle 2; the lengths of multiple sets of the expansion components are different. Specifically, the upper part of the lower handle 2 is inserted into the upper part of the upper handle 1 from below and is hinged to the upper part of the upper handle 1. During use, medical staff can select different specifications of expansion components to connect with the handle according to the situation of the examinee, so as to make the examination proceed smoothly. For example, for the normal population, expansion components with a shorter length are adopted, while for examinees with a higher hanging position of the cervix, when medical staff find that the length of the expansion component is not enough, another set of expansion components can be replaced to fully expose the cervix.
[0025] Please refer to Figures 2 - 4 , in an implementation manner, an observation hole 11 is provided on the upper part of the upper handle 1; the observation hole 11 penetrates through the upper part of the upper handle 1; on the side of the upper part of the upper handle 1 close to the upper insert 3, a first installation groove 12 is provided, and first insertion slots 13 are respectively provided on the left and right side walls of the first installation groove 12; the first insertion slots 13 are used to fix the upper insert 3 inserted from the rear end of the first installation groove 12. Specifically, the first installation groove 12 communicates with the observation hole 11. Through the observation hole 11, medical staff can observe the internal situation of the examinee's vagina from the outside.
[0026] Please refer to Figure 5 , in an implementation manner, a second installation groove 21 is provided on the side of the upper part of the lower handle 2 close to the lower insert 4; the second installation groove 21 penetrates through the upper part of the lower handle 2; second insertion slots 22 are respectively provided on the left and right side walls of the second installation groove 21; the second insertion slots 22 are used to fix the lower insert 4 inserted from the rear end of the second installation groove 21. Specifically, the second installation groove 21 communicates with the observation hole 11.
[0027] Please refer to Figure 5 and Figure 6 , in an implementation manner, the handle further includes two rotary dampers 5, and the two sides of the upper handle 1 and the lower handle 2 are respectively connected through the rotary dampers 5. The rotary dampers 5 are used to slow down the opening speed of the handle. During the examination, medical staff need to slowly open the expansion components through the handle to avoid causing pain and discomfort to the examinee. Due to the unstable operation level of medical staff, sometimes the opening speed of the handle may be relatively fast, which will cause discomfort to the examinee. By setting the rotary dampers 5, the opening speed of the handle can be effectively limited, thereby improving the examination comfort of the examinee.
[0028] Please refer to Figure 3 ,Figures 5 - 7 In one embodiment, the upper handle 1 includes two relatively arranged first side portions on the left and right. The first side portion includes a first inner wall 14 and a first outer wall 15. The lower handle 2 includes two relatively arranged second side portions on the left and right. The second side portion includes a second inner wall 23 and a second outer wall 24. The first inner wall 14 is arranged between the second inner wall 23 and the second outer wall 24. The rotary damper 5 is arranged between the first outer wall 15 and the second outer wall 24 and is respectively connected to the first outer wall 15 and the second outer wall 24. Specifically, the first slot 13 is arranged on the first inner wall 14, and the second slot 22 is arranged on the second inner wall 23.
[0029] Please refer to Figure 4 and Figure 5 In one embodiment, a buckle structure 6 is arranged at the lower part of the lower handle 2. The buckle structure 6 is arranged between the upper handle 1 and the lower handle 2. A strip hole 16 is arranged at the lower part of the upper handle 1. The buckle structure 6 passes through the strip hole 16. The buckle structure 6 is used to keep the pressed handle fixed. During the inspection, when the dilation assembly is opened by pressing the handle, it needs to be kept in the open state. At this time, the upper handle 1 is clamped by the buckle structure 6, so that the distance between the upper handle 1 and the lower handle 2 is kept fixed, thereby keeping the handle in the open state, and the medical staff does not need to continuously apply force to maintain it, and can release their hands to perform other operations.
[0030] Please refer to Figure 5 In one embodiment, the buckle structure 6 includes a rotating rod 61. One end of the rotating rod 61 is rotatably connected to the lower handle 2, and the other end thereof passes through the strip hole 16. A plurality of strip cards 62 are arranged in the middle of the rotating rod 61. The plurality of strip cards 62 are arranged in sequence along the length direction of the rotating rod 61. The plurality of strip cards 62 can pass through the strip hole 16. The plurality of strip cards 62 are used to fix the pressed upper handle 1 between two adjacent strip cards 62 after rotation. Specifically, the length of the strip card 62 is less than the length of the strip hole 16 and greater than the width of the strip hole 16. During the process of pressing the handle, the strip card 62 can pass through the strip hole 16. When the medical staff thinks that the opening degree is appropriate, the rotating rod 61 can be rotated. At this time, the plurality of strip cards 62 rotate with the rotating rod 61 and form a dislocation with the strip hole 16, so that the hole wall of the strip hole 16 is located between two strip cards 62 and cannot move, forming a fixation. Multiple positions are formed between the plurality of strip cards 62, so that the handle can be fixed by the buckle structure 6 when it reaches different opening degrees.
[0031] In summary, the present utility model enables medical staff to flexibly adjust the length of the vaginal speculum according to the situation of the examinee by setting a detachable handle and multiple groups of dilation assemblies, so that the cervix of the examinee can be fully exposed during the examination.
[0032] In addition, the utility model can further be provided with a rotary damper 5 to prevent the handle from opening too fast during the process, so that the examinee will experience less irritation and pain during the examination.
[0033] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solution of the utility model and its inventive concept, and all such changes or substitutions should fall within the protection scope of the appended claims of the utility model.
