[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0020] This application provides a stepless positioning vaginal speculum, which solves the technical problems of traditional vaginal speculum that use buckles, gears or knobs, resulting in jerky adjustments, inability to achieve fine adjustments, and easy wear and tear after long-term use, leading to a decrease in locking force and the risk of accidental slippage.

[0021] See Figure 1 , Figure 5 and Figure 6 As shown in the figure, this application embodiment provides a stepless positioning vaginal dilator, which includes: a handle 1 and a slider 5. The end of the handle 1 is provided with an upper leaf 2 and a lower leaf 3 that are hinged to each other. An opening and closing wrench 4 is rotatably installed on one side of the handle 1. The opening and closing wrench 4 is fixed to the lower leaf 3. The handle 1 is fixed to the upper leaf 2. The lower leaf 3 is provided with a slide rail 31. The slider 5 is slidably disposed on the slide rail 31. The slider 5 is connected to the opening and closing wrench 4 through a connecting rod 6. When the opening and closing wrench 4 is pressed, the upper leaf 2 and the lower leaf 3 change from a closed state to an open state. When the opening and closing wrench 4 is released, the slider 5 is magnetically fixed to the slide rail 31, and the upper leaf 2 and the lower leaf 3 are locked at a set opening degree.

[0022] In this embodiment, when the opening / closing lever 4 is pressed, the lower leaf 3 rotates downward, and the upper leaf 2 and the lower leaf 3 change from a closed state to an open state. The opening / closing lever 4 drives the connecting rod 6 to move and drives the slider 5 to slide along the slide rail 31. When the opening / closing lever 4 is released, the slider 5 is magnetically fixed to the slide rail 31, and the upper leaf 2 and the lower leaf 3 are locked at a set opening degree. By using the magnetic positioning of the slider 5 and the slide rail 31, the opening degree of the upper leaf 2 and the lower leaf 3 can be accurately adjusted to avoid accidental slippage. Exemplarily, the handle 1, the upper leaf 2 and the lower leaf 3 are all made of disposable medical-grade plastic material. The slider 5 is made of permanent magnets, which are arranged in an array. The magnetic field of the slider 5 is enhanced on one side to reduce the attraction force on non-working directions. The slide rail 31 is made of magnetically conductive material, and there is a gap between the slider 5 and the slide rail 31 to prevent the slider 5 and the slide rail 31 from getting stuck due to friction. In other embodiments, both the slider 5 and the slide rail 31 are permanent magnets, and the slider 5 and the slide rail 31 have opposite magnetic properties.

[0023] In other embodiments, the main body of the slider 5 is made of a non-magnetic material, the slider 5 is provided with a mounting groove, the mounting groove is located on the side of the slider 5 near the slide rail 31, a permanent magnet is installed in the mounting groove, and the slide rail 31 is made of a magnetically conductive material.

[0024] In this embodiment, a slide rail 31 is provided on the lower leaf 3, and a slider 5 slides on the slide rail 31. The slider 5 is connected to the opening and closing wrench 4 through the connecting rod 6. When the opening and closing wrench 4 is pressed, the upper leaf 2 and the lower leaf 3 change from a closed state to an open state. When the opening and closing wrench 4 is released, the slider 5 is magnetically fixed to the slide rail 31, and the upper leaf 2 and the lower leaf 3 are locked at a set opening degree. By using the magnetic positioning of the slider 5 and the slide rail 31, the opening degree of the upper leaf 2 and the lower leaf 3 can be precisely adjusted, avoiding accidental slippage. This solves the technical problems of traditional vaginal specula devices that use buckles, gears or knobs, which have a jerky adjustment feel, cannot achieve fine adjustment, and are prone to wear and tear after long-term use, resulting in a decrease in locking force and a risk of accidental slippage.

[0025] Further, see Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, the lower leaf 3 is provided with a guide groove 32, and the slide rails 31 are provided on both sides of the guide groove 32. The slider 5 is slidably disposed between the two slide rails 31. When the opening and closing lever 4 is pressed, the connecting rod 6 drives the slider 5 to slide along the guide groove 32. When the opening and closing lever 4 is released, the slider 5 is magnetically fixed to the slide rails 31, and the upper leaf 2 and the lower leaf 3 are locked at a set opening degree.

[0026] In this embodiment, the guide groove 32 is provided inside the lower leaf 3, and the slider 5 is limited to the guide groove 32. The handle 1 is mechanically linked to the opening and closing wrench 4. When the operator presses the opening and closing wrench 4, the opening and closing wrench 4 rotates, driving the connecting rod 6 to move, and driving the slider 5 to move between the two slide rails 31. A nonlinear magnetic force is generated between the slider 5 and the slide rail 31. During the opening or closing of the upper leaf 2 and the lower leaf 3, the slider 5 and the slide rail 31 generate uniform damping, realizing the smooth stepless adjustment of the infinitely positioned vaginal dilator. When the operator stops applying force, the magnetic force between the slider 5 and the slide rail 31 cancels the pulling force. The slider 5 can form a self-locking at any position on the slide rail 31. The connecting rod 6 and the opening and closing wrench 4 provide a reliable locking torque, so that the upper leaf 2 and the lower leaf 3 are locked at a set opening degree, preventing the slider 5 from accidentally slipping off the slide rail 31 and the lower leaf 3 from rebounding.

[0027] Further, see Figure 1 and Figure 5-7 As shown, in some embodiments, the connecting rod 6 is connected to the opening and closing wrench 4 via a torsion spring. When the opening and closing wrench 4 is released, the slider 5 is magnetically fixed to the slide rail 31, and the connecting rod 6 and the torsion spring lock the upper leaf 2 and the lower leaf 3 at a set opening degree.

[0028] In this embodiment, the torsion spring is wound around the hinge of the upper leaf 2 and the lower leaf 3. One end of the torsion spring is connected to the connecting rod 6, and the other end of the torsion spring is connected to the opening and closing wrench 4. When the opening and closing wrench 4 is pressed, the opening and closing wrench 4 rotates, thereby pulling the torsion spring and driving the connecting rod 6 to move, which in turn drives the slider 5 to move between the two slide rails 31. When the opening and closing wrench 4 is released, the slider 5 is magnetically fixed to the slide rail 31. Under the magnetic force between the slider 5 and the slide rail 31, the connecting rod 6 and the torsion spring provide a dragging force for the lower leaf 3, preventing the lower leaf 3 from rebounding, and realizing the locking of the upper leaf 2 and the lower leaf 3 at a set opening degree.

[0029] Further, see Figure 1-3 and Figure 8 As shown, in some embodiments, an LED light panel 7 is provided on the inner side of the upper leaf 2, and a light guide cover 8 is provided on one side of the LED light panel 7. The light guide cover 8 is fixed to the upper leaf 2. A circuit board 9 and a battery 10 are provided inside the handle 1. The circuit board 9 is electrically connected to the battery 10 and the circuit board 9 is electrically connected to the LED light panel 7.

[0030] In this embodiment, the front end of the upper leaf 2 is hemispherical, the LED light panel 7 is embedded in the upper leaf 2, and the light guide cover 8 is placed on top of the LED light panel 7. The LED light panel 7 and the light guide cover 8 form a dome light source, and the light is evenly scattered from directly above the operating area, completely eliminating the shadows caused by the operator's body blocking the external light source, and realizing shadowless lighting.

[0031] Further, see Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, heating elements 11 are provided on the outer sides of both the upper leaf 2 and the lower leaf 3. The surface of the heating elements 11 is coated with a buffer coating 12. A temperature sensor 13 is provided on the inner side of the heating elements 11. The temperature sensor 13 is electrically connected to the circuit board 9.

[0032] In this embodiment, the heating element 11 can preheat the outer surfaces of the upper leaf 2 and the lower leaf 3 to a set temperature in a short time. The set temperature is set to 36~38℃. When the temperature of the heating element 11 is greater than 42℃, the heating element 11 automatically cuts off the power. The heat is transferred through the buffer coating 12 to eliminate the cold stimulation caused by metal or plastic materials and improve patient comfort. The thickness of the buffer coating 12 is set to 0.3~0.8 mm. Exemplarily, the set temperature of the heating element 11 is set to 37℃, and the buffer coating 12 is made of silicone.

[0033] Further, see Figure 1 , Figure 8-10 As shown, in some embodiments, the outer side of the handle 1 is provided with a switch 14 and a dimming touch strip 15 spaced apart. The switch 14 is electrically connected to the LED light panel 7 and the heating element 11, the dimming touch strip 15 is electrically connected to the switch 14, and the dimming touch strip 15 is electrically connected to the LED light panel 7.

[0034] In this embodiment, the circuit board 9 is electrically connected to the switch 14 and the dimming touch strip 15. The switch 14 is used to control the LED light panel 7 or the heating element 11 to turn on. The dimming touch strip 15 is used to adjust the brightness of the LED light panel 7. Demonstratively, a short press of the switch 14 controls the LED light panel 7 to turn on the illumination. A long press of the switch 14 controls the heating element 11 to turn on preheating. Sliding the dimming touch strip 15 controls the LED light panel 7 to brighten. The LED light panel 7 and the heating element 11 are integrated into the stepless positioning vaginal speculum. The switch 14 and the dimming touch strip 15 are located on the handle 1 for convenient centralized control and are ergonomic.

[0035] Further, see Figure 1-3 As shown, in some embodiments, the LED light panel 7 extends along the width direction of the upper leaf 2.

[0036] In this embodiment, the LED light panel 7 is arranged in a ring along the upper leaf 2, so that the light source of the LED light panel 7 is evenly diffused. The LED light panel 7 and the light guide cover 8 are combined to form a dome light source, which completely eliminates the shadows caused by the operator's body blocking the external light source and realizes shadowless lighting.

[0037] Further, see Figure 1 and Figure 2 As shown, in some embodiments, an operation channel 16 is provided on one side of the upper leaf 2, and the operation channel 16 is inclined inward from the upper end of the upper leaf 2.

[0038] In this embodiment, the operation channel 16 is provided on the side wall of the upper leaf 2. The operation channel 16 is used to access the posterior fornix region of the vagina. A special long needle is used to pass through the operation channel 16 to accurately apply medication in the vagina, avoiding vaginal contamination caused by the use of conventional cotton swabs.

[0039] Further, see Figure 1 and Figure 2 As shown, in some embodiments, the upper leaf 2 is configured as an arc shape, and the upper leaf 2 bulges upward from the hinge point with the lower leaf 3.

[0040] In this embodiment, both the upper leaf 2 and the lower leaf 3 are designed in a duckbill shape. During insertion, the upper leaf 2 adheres to the vaginal wall, distributing the expansion force evenly to the vaginal wall, avoiding local pressure that could cause pain to the patient, and improving patient comfort.

[0041] Further, see Figure 1 and Figure 2 As shown, in some embodiments, the inner surface of the lower leaf 3 is set as a plane, the outer surface of the lower leaf 3 is set as an arc surface, and the width of the lower leaf 3 gradually decreases from the hinge point with the upper leaf 2.

[0042] In this embodiment, when the infinitely positioned vaginal dilator is in the closed state, the inner surface of the lower leaf 3 and the inner surface of the upper leaf 2 are in contact, the front end of the lower leaf 3 is set to be arc-shaped, and the width of the lower leaf 3 gradually decreases from the hinge point with the upper leaf 2, thereby increasing the arrangement space on the inner side of the lower leaf 3 and providing a wider support surface for the hinge point between the lower leaf 3 and the upper leaf 2.

[0043] Before operation, the infinitely positioned vaginal speculum is disinfected. The operator holds the handle 1 and inserts the closed upper leaf 2 and lower leaf 3 into the patient's vulva. The operator briefly presses the switch 14 to turn on the lighting. The brightness of the LED light panel 7 can be adjusted as needed. Alternatively, the operator presses the switch 14 for a long press to start the preheating. Then, the operator presses the opening and closing lever 4 until the opening degree of the upper leaf 2 and lower leaf 3 reaches the set value. The operator releases the opening and closing lever 4, and the slider 5 and the slide rail 31 automatically lock the upper leaf 2 and lower leaf 3 at the set opening degree. If posterior fornix marking is required, a special long needle is inserted along the operating channel 16 to accurately complete the operation. After use, the infinitely positioned vaginal speculum is discarded.
