Description

Technical Field

[0001] This utility model relates to the field of speculum technology, specifically to a convenient speculum. Background Technology

[0002] A speculum is used for vaginal examination. A woman's vagina is very deep. Its outer end is the labia majora and minora, and its inner end is the cervix. They are usually closed. If you want to check for lesions in the vagina and cervix, you must use a speculum to open the labia majora and minora and the vagina until the cervix and the surrounding vaginal fornix are exposed. The speculum is then withdrawn from the inside out while examining.

[0003] When using some existing speculums, the two blades of the speculum are brought together and slowly inserted into the vagina along the posterior wall of the vagina from the side, and then the two blades are opened.

[0004] Existing speculum devices have the following problems: the length of the speculum is fixed and cannot be adjusted according to the length of the patient's vagina. At the same time, the opening angle of the speculum is fixed, which is inconvenient for doctors to use and makes patients feel uncomfortable. Therefore, we propose a more convenient speculum device. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a convenient speculum. When using the speculum, it can be adjusted according to the length of the patient's vagina, and the opening angle of the speculum can be slowly adjusted, which is convenient for doctors to use and avoids making patients feel uncomfortable. It can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a convenient speculum, comprising an upper jaw plate, a lower jaw plate, a fixed handle, and an adjusting handle. The adjusting handle is fixedly connected to the tail of the upper jaw plate, and the angle between the upper jaw plate and the adjusting handle is 100-170°. The fixed handle is fixedly connected to the tail of the lower jaw plate, and the angle between the lower jaw plate and the fixed handle is 90°. The upper end of the adjusting handle is located on the outer side of the upper end of the fixed handle and forms an opening and closing structure through a rotating shaft located on the outer side of the fixed handle. An arc-shaped adjusting tooth plate is fixedly connected to the inner side of the lower part of the fixed handle. A square limiting hole is provided at the lower part of the adjusting handle. The bottom outer side of the arc-shaped adjusting tooth plate is provided with downward teeth, and one end of the arc-shaped adjusting tooth plate passes through the limiting hole. The teeth at the bottom of the arc-shaped adjusting tooth plate and the bottom edge of the limiting hole form a limiting structure that restricts the opening and closing range.

[0007] The upper jaw plate is fixedly provided with an upper duckbill head at its front end, and the lower jaw plate is movably connected to a lower duckbill head at its front end. The upper and lower duckbill heads together form a closed structure. The tail of the lower duckbill head is fixedly connected to a ball screw, and the tail of the ball screw extends to the upper part of the adjusting handle. By rotating the ball screw, the extension and retraction of the lower duckbill head can be adjusted. By adjusting the limiting position of the adjusting handle on the arc-shaped adjusting tooth plate, the opening range of the upper and lower jaw plates can be precisely adjusted.

[0008] Furthermore, the upper jaw plate has at least two side-by-side upward openings, and the lower jaw plate has at least two side-by-side downward openings at the bottom, for easy observation.

[0009] Furthermore, the upper jaw plate has an outwardly extending upper limit block at its rear end, and the lower jaw plate has an outwardly extending lower limit block at its rear end. The upper limit block and the lower limit block constitute a limiting mechanism that restricts the depth of entry into the vagina, thereby controlling the depth of the speculum entering the vagina.

[0010] Furthermore, the lower beak head and tail are provided with an extension section, which is disposed inside the lower jaw plate and forms a sliding structure with the lower jaw plate. The extension section normally overlaps with the lower jaw plate, and extends outward when the lower beak head extends.

[0011] Furthermore, a rotating nut is fixedly sleeved at the tail end of the ball screw. The nut is large in size and easy to rotate.

[0012] Furthermore, a bracket is provided on the upper part of the fixed handle, and the bracket is movably connected to the ball screw to support the ball screw.

[0013] Furthermore, both the upper and lower duckbill tips are made of solid silicone rubber, which reduces patient discomfort during use.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This easy-to-use speculum has the following advantages:

[0015] 1. The length of the speculum can be adjusted according to the vaginal length of different patients to achieve full exposure, thereby avoiding misdiagnosis and mistreatment;

[0016] 2. Furthermore, without affecting the internal opening angle, the external opening height is reduced. Traditional speculum generally has an opening height of >4 cm, while this easy-to-use speculum only needs to be opened by 3 cm to achieve the purpose of fully exposing the cervix and vaginal fornix, which can greatly reduce the patient's discomfort and pain.

[0017] 3. The addition of a window design allows for effective and maximum observation of the entire vaginal mucosa, reducing the risk of missed diagnoses: Traditional speculum does not have a window design, making it difficult to observe the vaginal mucosa and increasing the risk of missed diagnoses.

The adjusting handle 4 is fixedly connected to the tail of the upper jaw plate 1, and the angle between the upper jaw plate 1 and the adjusting handle 4 is 100-170°. For a better user experience, the angle between the upper jaw plate 1 and the adjusting handle 4 can be set to 135°. The fixed handle 3 is fixedly connected to the tail of the lower jaw plate 2, and the angle between the lower jaw plate 2 and the fixed handle 3 is 90°. The upper end of the adjusting handle 4 is mounted on the fixed handle 3. The outer side of the fixed handle 3 forms an opening and closing structure through a rotating shaft set on the outer side of the fixed handle 3. Nuts, baffles and other limiting parts are set on the outer side of the rotating shaft. An upwardly extending arc-shaped adjusting tooth plate 6 is fixedly connected to the lower inner side of the fixed handle 3. A square limiting hole 7 is set at the lower part of the adjusting handle 4. The bottom outer side of the arc-shaped adjusting tooth plate 6 is provided with downward teeth. Each tooth is equal to an adjustment position. One end of the arc-shaped adjusting tooth plate 6 passes through the limiting hole 7. The teeth at the bottom of the arc-shaped adjusting tooth plate 6 and the bottom edge of the limiting hole 7 form a limiting structure that limits the opening and closing range.

[0027] An upper duckbill head 11 is fixedly installed at the front end of the upper jaw plate 1, and a lower duckbill head 21 is movably connected to the front end of the lower jaw plate 2. The upper duckbill head 11 and the lower duckbill head 21 are closed together to form a closed structure. The tail of the lower duckbill head 21 is fixedly connected to the ball screw 5. The tail of the ball screw 5 extends to the upper part of the adjusting handle 4. By rotating the ball screw 5, the extension and retraction of the lower duckbill head 21 are adjusted. By adjusting the limiting position of the adjusting handle 4 on the arc-shaped adjusting tooth plate 6, the opening range of the upper jaw plate 1 and the lower jaw plate 2 can be precisely adjusted.

[0028] In one embodiment, the upper jaw plate 1 has at least two side-by-side upper openings 12, and the lower jaw plate 2 has at least two side-by-side lower openings 22 at its bottom, for easy observation.

[0029] In one embodiment, the upper jaw plate 1 has an outwardly extending upper limit block 13 at its rear end, and the lower jaw plate 2 has an outwardly extending lower limit block 23 at its rear end. The upper limit block 13 and the lower limit block 23 constitute a limiting mechanism that restricts the depth of entry into the vagina, thereby controlling the depth of the speculum entering the vagina.

[0030] In one embodiment, the lower duckbill head 21 is provided with an extension section at its tail. The extension section is disposed inside the lower jaw plate 2 and forms a sliding structure with the lower jaw plate 2. The extension section normally overlaps with the lower jaw plate 2, and when the lower duckbill head 21 extends, the extension section extends outward accordingly.

[0031] In one embodiment, a rotating nut 8 is fixedly sleeved at the tail end of the ball screw 5. The nut is large in size and easy to rotate.

[0032] In one embodiment, a bracket is provided on the upper part of the fixed handle 3, and the bracket is movably connected to the ball screw 5 to support the ball screw 5.

[0033] For a better user experience, both the upper duckbill tip 11 and the lower duckbill tip 21 are made of solid silicone rubber, which reduces patient discomfort during use.

[0034] The working principle of the convenient speculum provided by this utility model is as follows: When using the speculum, the upper jaw plate 1 and lower jaw plate 2 of the speculum are brought together and slowly inserted into the vagina laterally along the posterior wall of the patient's vagina. By operating the fixed handle 3 and the adjusting handle 4, the upper jaw plate 1 and lower jaw plate 2 are opened and closed through the opening and closing structure. By adjusting the limiting position of the adjusting handle 4 on the arc-shaped adjusting tooth plate 6, the opening range of the upper jaw plate 1 and lower jaw plate 2 can be precisely adjusted to reduce the patient's discomfort during the examination. When the length needs to be adjusted, the rotational motion is converted into linear motion through the ball screw 5. Rotating the ball screw 5 can adjust the extension and retraction of the lower duckbill head 21, thereby fine-tuning the length of the speculum to suit different patients.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
