Description

Technical Field

[0001] This utility model relates to the field of vaginal speculum technology, specifically to an improved gynecological vaginal speculum. Background Technology

[0002] Gynecological speculum is a commonly used medical instrument in gynecological examinations. Its design typically employs a two-piece, duckbill-shaped structure. During use, the speculum is inserted into the vagina, and then the two duckbill-shaped pieces are opened by manipulating the handle, thereby exposing the cervix and vaginal walls for easier examination by the doctor. However, existing gynecological speculum has the following problems:

[0003] 1. Dry Material: Traditional vaginal speculum are mostly made of hard plastic or metal, and their surfaces are relatively dry and lack sufficient lubrication. This can cause discomfort or pain when using the speculum, especially in cases of vaginal dryness or sensitivity.

[0004] 2. Inadequate cervical exposure: In patients with thickened or abnormally shaped vaginas, the vaginal wall can easily get squeezed into the speculum after the traditional duckbill speculum is opened, resulting in insufficient cervical exposure. This not only increases the difficulty of the examination but also affects the accuracy of the diagnosis.

[0005] 3. Difficulty in selecting the right size: Although vaginal speculum comes in various sizes to suit different patients' vaginal sizes and shapes, doctors often find it difficult to accurately estimate the size required by each patient during actual operation. This can easily result in a speculum that is too large or too small, affecting the smooth progress of the examination and the patient's comfort. Utility Model Content

[0006] (I) Purpose of the utility model

[0007] In view of this, the purpose of this utility model is to propose an improved gynecological vaginal speculum that solves the problems mentioned in the background above.

[0008] (II) Technical Solution

[0009] An improved gynecological vaginal speculum includes a mounting plate. A limiting ring is fixedly mounted on one side of the mounting plate, and a housing is fixedly mounted on one side of the limiting ring. The outer surface of the housing has multiple sets of limiting straight grooves. A turntable is movably mounted between the housing and the limiting ring. The outer surface of the turntable has multiple sets of arc-shaped grooves. A round rod is movably mounted on the inner wall of the multiple sets of arc-shaped grooves. One end of the round rod is connected to a sliding block. The sliding block is movably mounted on the inner wall of the limiting straight groove, and one end of the sliding block is connected to an expansion piece.

[0010] Preferably, the inner wall of the dilator has a cavity, and a connecting piece is movably installed in the cavity. One end of the connecting piece is connected to an adjusting piece. The cavity design allows the connecting piece to move flexibly inside the dilator. This flexibility allows the adjusting piece to be adjusted in position and length as needed, thereby better adapting to the vaginal size and shape of different patients and improving the applicability and comfort of the speculum.

[0011] Preferably, the outer surfaces of the expansion piece, connecting piece, and adjusting piece are all coated with medical-grade silicone. Medical-grade silicone is a safe, non-toxic, and biocompatible material that effectively reduces friction and irritation to the vaginal wall, thus reducing patient discomfort. Furthermore, the softness and elasticity of silicone also contribute to improved speculum comfort and protect vaginal tissue from damage.

[0012] Preferably, an operating lever is connected to one outer surface of the turntable. The operating lever provides the operator with an intuitive and easy-to-grip control point, allowing them to drive the rotation of the turntable by simply rotating the operating lever, thus simplifying the operation process and improving operational efficiency.

[0013] Preferably, the bottom end of the mounting plate is connected to a handle, which provides a stable grip point for the operator, enabling them to maintain effective control of the speculum during operation. This helps reduce operational errors and improve the accuracy of diagnosis or treatment.

[0014] Preferably, the outer surface of the grip is covered with a rubber sleeve, which increases the friction and grip comfort of the grip, so that the operator can keep their hands comfortable and reduce fatigue during long-term use.

[0015] Preferably, the front section of the adjustment piece is arc-shaped. This arc-shaped design is more ergonomic, allowing it to fit more smoothly against the vaginal wall and reducing friction and discomfort. This design also helps improve the stability and uniformity of the speculum during dilation, thereby reducing the risk of damage to vaginal tissue.

[0016] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0017] 1. This utility model utilizes a flexible stretching design of the connecting piece within the cavity of the dilator to achieve free adjustment of the dilator's length. This innovative design significantly enhances the speculum's applicability and personalized service capabilities. Regardless of the patient's body type, age, or pathological condition, operators can easily adjust the speculum to perfectly fit the patient's vaginal structure and size, ensuring the accuracy and effectiveness of diagnosis or treatment. This not only improves the precision of medical services but also significantly enhances patient comfort and acceptance.

[0018] 2. This utility model ensures the stability and accuracy of the vaginal dilation process through a precision transmission system composed of a turntable, a round rod, and a sliding block. The operator can easily drive the sliding block to move linearly within the limiting groove by simply rotating the turntable with the operating lever. This, in turn, drives the dilator and adjusting plate to perform precise linear dilation, simplifying the operation process, reducing operational difficulty, and significantly improving the controllability and safety of the dilation process.

[0025] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0026] Please see Figure 1-5 One embodiment provided by this utility model:

[0027] An improved gynecological vaginal speculum includes a mounting plate 1. A limiting ring 2 is fixedly mounted on one side of the mounting plate 1, and a housing 3 is fixedly mounted on one side of the limiting ring 2. Multiple sets of limiting straight grooves 311 are formed on the outer surface of the housing 3. A turntable 112 is movably mounted between the housing 3 and the limiting ring 2. Multiple sets of arc-shaped grooves 113 are formed on the outer surface of the turntable 112. A round rod 114 is movably mounted on the inner wall of the multiple sets of arc-shaped grooves 113. A sliding block 4 is connected to one end of the round rod 114. The sliding block 4 is movably mounted on the inner wall of the limiting straight groove 311, and an expansion piece 5 is connected to one end of the sliding block 4.

[0028] Furthermore, the inner wall of the dilator 5 has a cavity, and a connecting piece 6 is movably installed in the cavity. One end of the connecting piece 6 is connected to an adjusting piece 7. The cavity design allows the connecting piece 6 to move flexibly inside the dilator 5. This flexibility allows the adjusting piece 7 to adjust its position and length as needed, thereby better adapting to the vaginal size and shape of different patients and improving the applicability and comfort of the speculum.

[0029] Furthermore, the outer surfaces of the dilator 5, connecting piece 6, and adjusting piece 7 are all coated with medical-grade silicone. Medical-grade silicone is a safe, non-toxic, and biocompatible material that effectively reduces friction and irritation to the vaginal wall, lowering patient discomfort. In addition, the softness and elasticity of silicone also contribute to improved speculum comfort and protect vaginal tissue from damage.

[0030] Furthermore, an operating lever 111 is connected to one outer surface of the turntable 112. The operating lever 111 provides the operator with an intuitive and easy-to-grip control point, allowing them to drive the rotation of the turntable 112 by simply rotating the operating lever, which simplifies the operation process and improves the operating efficiency.

[0031] Furthermore, a handle 8 is connected to the bottom of the mounting plate 1. The handle 8 provides a stable grip point for the operator, enabling them to maintain effective control of the speculum during operation. This helps reduce operational errors and improve the accuracy of diagnosis or treatment.

[0032] Furthermore, the outer surface of the grip 8 is covered with a rubber sleeve 9, which increases the grip friction and grip comfort, allowing the operator to keep their hands comfortable and reduce fatigue during long-term use.

[0033] Furthermore, the front section of the adjustment piece 7 is arc-shaped. This arc-shaped design is more ergonomic, allowing it to fit more smoothly against the vaginal wall and reducing friction and discomfort. This design also helps improve the stability and uniformity of the speculum during dilation, thereby reducing the risk of damage to vaginal tissue.

[0034] Working Principle: First, the connecting piece 6 can be flexibly stretched within the cavity of the dilator 5, allowing the adjusting piece 7 to freely adjust its length as needed to suit different patients. When vaginal dilation is required, the operator can hold the handle 8 covered with a rubber sleeve 9 with one hand to increase stability and comfort. The other hand rotates the turntable 112 via the operating rod 111. As the turntable 112 rotates, the round rod 114 slides smoothly within the arc-shaped groove 113, further driving the movement of the sliding block 4. Under the strict constraint of the limiting straight groove 311, the sliding block 4 can only move in a straight line, ensuring the accuracy and stability of the dilation process. With the linear movement of the sliding block 4, the dilator 5 and its adjusting piece 7 expand linearly, thus achieving effective vaginal dilation. After dilation, the operator can pass through the central circular through-hole.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
