A circular opening is opened in the middle of the gasket 1, and a circular seat ring 101 is rotatably connected to the inner side of the circular opening. The inner diameter of the seat ring 101 is larger than the maximum width of the connecting ring 2, and the edges of the gasket 1 and the seat ring 101 both adopt an arc structure.

[0037] In this embodiment, when the vaginal speculum is in use, the gasket 1 is attached to the outside of the labia to assist in positioning the vaginal speculum. The gasket 1 is configured to be an ellipse with notches on both sides to leave space for the thigh root. The edges of the gasket 1 and the seat ring 101 both adopt an arc structure to improve comfort.

[0038] Specifically, the connecting ring 2 is an octagonal structure, and is provided with a long side 201 and a short side 202. The long side 201 and the short side 202 are arranged alternately. Four spoon-shaped blades 3 are provided, and the four spoon-shaped blades 3 are rotatably connected to the middle of the short side 202 through a connecting buckle 32. A protrusion 203 is provided on the surface of the short side 202, and the protrusion 203 is symmetrically arranged on the left and right sides of the connecting buckle 32. One end of the connecting rod 26 is vertically connected to the middle of the long side 201, and the other end of the connecting rod 26 is connected to the seat ring 101 by bolts.

[0039] In the present embodiment, the setting of the connecting ring 2 plays a combined connecting role for the spoon-shaped blades 3. Four spoon-shaped blades 3 are connected through the connecting ring 2 to form a bud structure. The opening of the four spoon-shaped blades 3 has a stretching effect on the vagina. The protrusion 203 on the surface of the short side 202 plays a limiting role on the connecting buckle 32, reducing the shaking of the connecting buckle 32. The connecting ring 2 is connected to the seat ring 101 through the connecting rod 26, which plays a combined connecting role for the gasket 1 and the connecting ring 2, thereby combining the gasket 1 and the spoon-shaped blades 3.

[0040] Specifically, the first transmission rod 21 and the second transmission rod 22 are rotatably connected inside the short side 202 and the long side 201 respectively, the bevel gears 23 on the first transmission rod 21 and the second transmission rod 22 are meshed with each other, and one side of the transmission gear 25 extends to the outside of the connecting ring 2 and is meshed with the tooth groove 24 on the inner wall of the connecting buckle 32; the spoon-shaped blade 3 is recorded as a first blade 301, a second blade 302, a third blade 303 and a fourth blade 304, and the first blade 301, the second blade 302, the third blade 303 and the fourth blade 304 are arranged clockwise, the first blade 301 is fixedly connected to the operating handle 5, and the third blade 303 is fixedly connected to the positioning handle 4, the positioning handle 4 and the operating handle 5 are both set to be L-shaped, and the positioning handle 4 and the operating handle 5 are overlapped.

[0041] In this embodiment, when a spoon-shaped blade 3 is deflected, the connecting buckle 32 rotates on the short side 202, and the transmission gear 25 is driven to rotate through the tooth groove 24 on the inner wall of the connecting buckle 32, thereby driving the first transmission rod 21 to rotate, and through the engagement of each bevel gear 23, the remaining first transmission rods 21 and second transmission rods 22 rotate accordingly, thereby driving the other three spoon-shaped blades 3 to deflect synchronously, and the first blade 301 and the third blade 303 are driven to turn outward by pinching the positioning handle 4 and the operating handle 5, thereby driving the second blade 302 and the fourth blade 304 to turn outward.

[0042] Specifically, the through slot 52 is configured to be in a strip shape, the width of the through slot 52 is greater than the diameter of the screw 41 , the screw 41 passes through the through slot 52 , the middle portion of the adjusting button 42 is spherical, and side ears are provided on both sides, and the adjusting button 42 is provided on the side of the operating handle 5 away from the positioning handle 4 .

[0043] In this embodiment, when the adjusting button 42 rotates, it slides on the screw rod 41 through the action of the thread, and the adjusting button 42 presses the operating handle 5 to move closer to the positioning handle 4, thereby driving the first blade 301 and the third blade 303 to turn outward.

[0044] Specifically, the middle portion of the elastic rod 53 is bent into a V-shape, the surface of the pad 44 is concave, and the side of the elastic rod 53 facing away from the operating handle 5 is attached to the concave portion of the pad 44 .

[0045] In the present embodiment, the two ends of the V-shaped elastic rod 53 respectively abut against the positioning handle 4 and the operating handle 5. During the process of squeezing the positioning handle 4 and the operating handle 5, the elastic rod 53 is squeezed to produce elastic deformation. After the positioning handle 4 and the operating handle 5 are released, the pressure on the elastic rod 53 disappears, and the positioning handle 4 and the operating handle 5 are elastically pushed back to their original positions by the elastic rod 53.

[0046] Specifically, a lithium battery 5501 is arranged on the inner side of the lighting fixture 55, a switch 5502 is arranged on the side, and LED lamp heads 5503 are arranged at both ends. A conical reflector is fixedly installed on the inner side of the spotlight cover 56. The lighting hose 57 is arranged based on a transparent silicone tube. One end of the lighting hose 57 is open and the other end is closed in an arc shape.

[0047] In this embodiment, the switch key 5502 is set based on a single-pole double-throw electric key switch. The switch key 5502 is electrically connected between the lithium battery 5501 and the LED lamp head 5503. The switch key 5502 controls the switch of the two LED lamp heads 5503. The LED lamp head 5503 on one side of the lighting fixture 55 is nested inside the spotlight cover 56. The spotlight cover 56 converges light to illuminate the inside of the vagina. The LED lamp head 5503 on the other side of the lighting fixture 55 is nested inside the lighting hose 57. The lighting hose 57 guides the light emitted by the LED lamp head 5503. The lighting hose 57 extends into the vagina to illuminate the deep part of the vagina.

[0048] Specifically, the inner wall of the spoon-shaped blade 3 is provided with an arc-shaped concave, and the lighting hose 57 is inlaid with a magnetic buckle.

[0049] In this embodiment, when the lighting hose 57 is inserted into the vagina, it is located on the inner side of the spoon-shaped blade 3. The lighting hose 57 is adsorbed on the concave part on the inner side of the spoon-shaped blade 3 by the magnetic buckle, thereby positioning the lighting hose 57 and preventing the lighting hose 57 from deviating inside the vagina.

[0050] When in use, the spoon-shaped blade 3 is inserted into the vagina, the gasket 1 is attached to the outside of the vagina, the positioning handle 4 and the operating handle 5 are pinched, the positioning handle 4 and the operating handle 5 are brought close to each other and squeeze the elastic rod 53, thereby driving the spoon-shaped blade 3 connected to the positioning handle 4 and the operating handle 5 to deflect outward, and the other two spoon-shaped blades 3 are driven to deflect synchronously through the transmission of the first transmission rod 21, the second transmission rod 22 and the bevel gear 23, so that the four spoon-shaped blades 3 are synchronously expanded outward to open the vagina, and the adjusting knob 42 is turned to make the adjusting knob 42 approach the positioning handle 4 and close to the operating handle 5, so as to fix the angle between the positioning handle 4 and the operating handle 5, and thus fix the expansion angle of the spoon-shaped blade 3;

[0051] When the vaginal speculum needs to be taken out, the adjusting knob 42 is rotated in the opposite direction, so that the positioning handle 4 and the operating handle 5 are reset under the action of the elastic rod 53, and the spoon-shaped blade 3 is also reset under the action of the positioning handle 4 and the operating handle 5;

[0052] During the process of examining the vagina, when it is necessary to examine the vaginal opening, the spotlight cover 56 on the lighting fixture 55 is pointed toward the vagina, and the LED lamp head 5503 on one side of the spotlight cover 56 is turned on by the switch 5502 to illuminate the vaginal opening. When it is necessary to examine the deep part of the vagina, a lighting hose 57 of a suitable length is selected according to the patient's body shape and vaginal depth and is threadedly connected to the lighting fixture 55. The lighting hose 57 on the lighting fixture 55 is extended into the interior of the vagina, and the lighting hose 57 is moved to make it adhere to the inner wall of the spoon-shaped blade 3, and the interior of the vagina is illuminated by the lighting hose 57.

[0053] In summary, the vaginal speculum is provided with a connecting ring 2 to connect four spoon-shaped blades 3. When not in use, the four spoon-shaped blades 3 are closed together to form a bud shape. During use, the four spoon-shaped blades 3 are opened synchronously to support the vagina from four directions, increase the number of supporting sites, and cooperate with the hollowing 31 on the spoon-shaped blades 3 to expand the exposed area of ​​the inner wall of the vagina on the inner side of the vaginal speculum, increase the area of ​​the part that can be observed from the vaginal speculum, and improve the convenience of observation through the vaginal speculum;

[0054] By setting the operating handle 5 to connect the hanger 54, the lighting fixture 55 is set at a position facing the inner wall of the vagina. By setting a spotlight cover 56 and a lighting hose 57 at both ends of the lighting fixture 55, the vaginal opening and the inner side of the vagina are illuminated respectively, which plays an auxiliary lighting role in vaginal treatment, improves the convenience of vaginal treatment, and meets the needs of different vaginal disease treatments.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
