[0031] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0032] like Figure 1 , 2 As shown in , 3, and 6, the embodiment of the utility model discloses a vaginal speculum dedicated to cervical treatment support, including an upper support plate 1 and a lower support plate 2, the middle part of the upper support plate 1 is hinged to the middle part of the lower support plate 2, the cross-sections of the upper support plate 1 and the lower support plate 2 are both V-shaped, the upper support plate 1 includes a first clamping plate 11 located at the bottom of the upper support plate 1, the lower support plate 2 includes a second clamping plate 21 located at the bottom of the lower support plate 2, a buckle mechanism 3 is provided between the first clamping plate 11 and the second clamping plate 21, The buckle mechanism 3 includes a card slot 31 that passes through the first card plate 11, an arc rod 32 is provided on the second card plate 21, and a serration 33 is provided on the arc rod 32. The arc rod 32 passes through the card slot 31, and the serration 33 abuts against the upper edge of the card slot 31. The serration 33 is inclined from top to bottom from the direction of the second card plate 21 to the direction of the first card plate 11, and an unlocking rod 34 is fixedly connected to the bottom surface of one end of the arc rod 32 away from the second card plate 21.

[0033] Specifically, when in use, the upper support plate 1 and the lower support plate 2 are inserted into the patient's body, and then the first clamping plate 11 and the second clamping plate 21 are operated to make the first clamping plate 11 and the second clamping plate 21 close to each other. During the process of the first clamping plate 11 and the second clamping plate 21 approaching each other, the arc rod 32 slides in the clamping groove 31, so that the saw teeth 33 are constantly in contact with the upper edge of the clamping groove 31. Due to the effect of the inclined direction of the saw teeth 33, the first clamping plate 11 and the second clamping plate 21 cannot move in opposite directions. When the upper support plate 1 and the lower support plate 2 are When the patient's vagina is stretched to the appropriate position, stop moving the first clamping plate 11 and the second clamping plate 21 closer together. At this time, under the action of the serrations 33, the opening angle of the upper support plate 1 and the lower support plate 2 is maintained. Then the operator puts the cervical support into the patient's cervix. Then the operator presses the unlocking rod 34 downward to make the arc rod 32 bend downward, so that the serrations 33 are out of contact with the upper edge of the slot 31. The upper support plate 1 and the lower support plate 2 are closer to each other under the squeezing action of the patient's body, making it convenient for the operator to remove the speculum from the patient's vagina.

[0034] By setting the buckle mechanism 3, the operator can insert the speculum into the patient's vagina with one hand. At the same time, during the operation, the serrations 33 can clamp the first clamping plate 11 and the second clamping plate 21, so that the opening angle of the upper support plate 1 and the lower support plate 2 can be maintained, and when the speculum needs to be pulled out after use, the operator can press the unlocking rod 34 downward with a finger to unlock the buckle mechanism 3, which is convenient for taking out the speculum, thereby enabling the operator to open and retract the speculum with one hand, which is convenient for inserting the treatment tray.

[0035] like Figure 3 As shown, the buckle mechanism 3 also includes an anti-error component 35, which includes a baffle 351 slidably connected to the first clamping plate 11, a spring 352 is connected between the baffle 351 and the first clamping plate 11, the baffle 351 is located on the lower side of the arc rod 32, and two limit plates 353 are symmetrically fixedly connected to the first clamping plate 11, and the baffle 351 is located between the limit plate 353 and the first clamping plate 11.

[0036] Specifically, when in use, the spring 352 is always in a compressed state. Under the elastic force of the spring 352, the baffle 351 always applies an upward force to the arc rod 32, thereby applying an upward force to the serrations 33, keeping the serrations 33 in contact with the upper edge of the slot 31; when the unlocking rod 34 moves downward, the unlocking rod 34 drives the baffle 351 to move downward through the arc rod 32, compressing the spring 352.

[0037] By setting the error-proofing member 35, the arc rod 32 applies an upward force to the sawtooth 33 to maintain the stability of the buckle mechanism 3, thereby preventing the operator from accidentally touching the unlocking rod 34, causing the speculum to retract and affecting the subsequent work.

[0038] like Figure 2 As shown, the lower support plate 2 includes an insertion section 22, the end of the insertion section 22 is fixedly connected to a peeping section 23, the second clamping plate 21 is fixedly connected to the bottom of the peeping section 23, and the inner diameter of the peeping section 23 is larger than the inner diameter of the insertion section 22.

[0039] like Figure 2 As shown, the upper support plate 1 includes an expansion section 12, the end of the expansion section 12 is fixedly connected to a hinge section 13, the first clamping plate 11 is fixedly connected to the bottom of the hinge section 13, the inner diameter of the hinge section 13 is larger than the inner diameter of the expansion section 12, and the hinge section 13 is hinged to the peeping section 23.

[0040] like Figure 1 , 2As shown, a ventilation mechanism 4 is provided between the lower support plate 2 and the upper support plate 1, and the ventilation mechanism 4 includes a ventilation hole group symmetrically arranged on the expansion section 12 and the insertion section 22, and the ventilation hole group includes ten ventilation holes 41 arranged at equal intervals along the same straight line.

[0041] Specifically, when in use, when the expansion section 12 and the insertion section 22 expand the patient's vagina, the ventilation holes 41 expose part of the patient's vaginal mucosa.

[0042] By setting the air holes 41, part of the patient's vaginal mucosa can be exposed therefrom, making the patient feel comfortable and avoiding the patient's vaginal mucosa being compressed by the stretching section 12 and the insertion section 22 for a long time when the vagina is stretched for a long time, causing discomfort to the patient.

[0043] like Figure 7 , 8 As shown, the ventilation mechanism 4 also includes an air groove 42 opened downward in the second clamping plate 21, a push plate 43 is slidably connected in the air groove 42, the bottom surface of the push plate 43 is fixedly connected to the connecting rod 44, a connecting cavity 45 is opened in the insertion section 22, the connecting cavity 45 is connected with a connecting groove, the connecting groove is connected to the air hole 41 on the insertion section 22, the connecting cavity 45 is connected to the air groove 42 through a connecting groove 46, and a return spring 47 is connected between the push plate 43 and the inner wall of the air groove 42.

[0044] Specifically, when in use, the operator pulls the connecting rod 44 downward, so that the connecting rod 44 drives the push plate 43 to move downward, and at the same time compresses the return spring 47, thereby driving the flow of gas inside the speculum through the gas groove 42, the connecting groove 46, the connecting cavity 45 and the air vent 41; then the operator releases the connecting rod 44, and the push plate 43 moves upward under the action of the return spring 47, blowing the gas in the gas groove 42 out through the air vent 41.

[0045] By providing the air permeable mechanism 4, the gas flow inside the speculum can be driven, thereby improving the patient's comfort level and preventing the patient from feeling uncomfortable.
