[0059] The following describes in detail, with reference to the accompanying drawings, an embodiment of the fixable vaginal speculum of this utility model.

[0060] Reference Figures 1 to 5 As shown, the fixable vaginal speculum provided according to the embodiment of the present invention includes an expansion component, a locking component 30, and a cleaning fluid supply component 40.

[0061] The expansion assembly includes an upper expansion member 10 and a lower expansion member 20, both of which have a 7-shaped structure, including an expansion end 11 and a handle end 21. The upper expansion member 10 and the lower expansion member 20 are movably connected, and the upper expansion member 10 can switch between a first position and a second position relative to the lower expansion member 20. When the upper expansion member 10 is switched to the first position, the expansion end 11 of the upper expansion member 10 and the expansion end 11 of the lower expansion member 20 retract towards each other. When the upper expansion member 10 is switched to the second position, the expansion end 11 of the upper expansion member 10 and the expansion end 11 of the lower expansion member 20 move away from each other.

[0062] The dilator assembly is used to open the vagina and specifically includes an upper dilator 10 and a lower dilator 20. The upper dilator 10 and the lower dilator 20 are movably connected and can be switched between a closed position and a remote position. Specifically, when they are in the closed position, the dilating ends 11 of the upper dilator 10 and the lower dilator 20 are close to each other. At this time, the distance between the dilating ends 11 of the upper dilator 10 and the lower dilator 20 is the smallest, so the dilating ends 11 of both can be inserted into the vagina by operating their handles. After insertion into the vagina, the handles 21 can be operated to switch them to the remote position. At this time, the distance between the dilating ends 11 of the upper dilator 10 and the lower dilator 20 will increase, and the vagina can be opened accordingly, thus facilitating medical staff to observe the patient's vaginal condition.

[0063] The locking component 30 is disposed on the lower expansion member 20 and is used to lock the upper expansion member 10 when the upper expansion member 10 is switched to the second position.

[0064] The locking component 30 has a locking function, which can lock the upper dilator 10 and the lower dilator 20 when they open the vagina, so that the upper dilator 10 and the lower dilator 20 remain in the corresponding open state. In this way, medical staff do not need to manually hold the application to keep it in the locked state, thereby reducing the burden on medical staff.

[0065] The cleaning fluid supply component 40 is connected to the locking component 30 and is used to deliver cleaning fluid into the vagina through the locking component 30.

[0066] In other words, the cleaning solution supply component 40 and the locking component 30 can form a passage to deliver the cleaning solution or medicine from outside the vagina to inside the vagina for rinsing or treatment, thereby greatly improving the practical performance of this application.

[0067] More specifically, in use, the upper dilator 10 and lower dilator 20 can be switched to the first position, where the dilating ends 11 of the upper dilator 10 and lower dilator 20 are closest together, allowing them to be inserted into the vagina. Then, the upper dilator 10 and lower dilator 20 can be switched to the second position, increasing the distance between their dilating ends 11, thus opening the vagina. Furthermore, the upper dilator 10 and lower dilator 20 can be locked by the locking component 30, maintaining their respective positions and supporting the vagina. Additionally, a cleaning solution or medication can be delivered into the vagina through the passage formed by the cleaning solution supply component 40 and the locking component 30 for cleaning or treatment.

[0068] According to the fixed vaginal speculum provided by this utility model, on the one hand, it can be fixed when the dilation component opens the vagina, so that the dilation component is kept in the opened position without the need for medical staff to hold it manually; on the other hand, it can also deliver cleaning fluid or medicine into the vagina to facilitate the treatment of related gynecological diseases.

[0069] Advantageously, in one embodiment of the present invention, two rotating shafts 22 are provided opposite each other at the middle position on the outer wall of the lower expansion member 20;

[0070] Two sliding holes 12 are provided opposite each other at the middle position of the upper expansion member 10. The two sliding holes 12 extend in the vertical direction and are movably connected to the two rotating shafts 22 so that the upper expansion member 10 and the lower expansion member 20 can switch between the first position and the second position.

[0071] Furthermore, when the upper expansion member 10 is switched to the first position, the handle end 21 of the upper expansion member 10 moves away from the handle end 21 of the lower expansion member 20;

[0072] When the upper expander 10 is switched to the second position, the handle end 21 of the upper expander 10 retracts into the handle end 21 of the lower expander 20, and is adapted to move up and down within the handle end 21 of the lower expander 20.

[0073] In other words, during the process of switching the upper dilator 10 from the first position to the second position, the handle end 21 of the upper dilator 10 can be pressed first, so that the handle end 21 of the upper dilator 10 is brought together with the handle end 21 of the lower dilator 20. In this way, the dilating end 11 of the upper dilator 10 and the dilating end 11 of the lower dilator 20 can be separated from each other to open the vaginal wall. Specifically, in use, when the upper dilator 10 is switched to the first position, the dilator 10 and the dilator end 11 of the lower dilator 20 are inserted into the vagina. Then, the handle end 21 of the upper dilator 10 is pressed, causing the rotating shaft 22 on the lower dilator 20 to retract onto the handle end 21 of the lower dilator 20. In this way, the dilator end 11 of the upper dilator 10 can cooperate with the dilator end 11 of the lower dilator 20 to open the vaginal wall. Furthermore, by sliding the handle end 21 of the upper dilator 10 upward along the handle end 21 of the lower dilator 20, the sliding hole 12 on the upper dilator 10 slides upward along the rotating shaft 22 on the lower dilator 20, which allows the upper dilator 10 to move upward and thus open the vaginal opening. In this way, the entire vagina can be opened. Then, by locking with the locking component 30, the dilator components can be kept in the dilated state, which is convenient for medical staff to perform a first vaginal examination.

[0074] Advantageously, in one embodiment of the present invention, the locking assembly 30 includes a vertical tube 31, a limiting stop 32, and a locking member 33; the vertical tube 31 is vertically disposed at the handle end 21 of the lower expansion member 20, and has external threads on its outer wall;

[0075] The limiting stop 32 is disposed opposite to the handle end 21 of the lower expansion member 20, and is used to limit the handle end 21 of the upper expansion member 10 within the handle end 21 of the lower expansion member 20 when the upper expansion member 10 is switched to the second position; the locking member 33 is sleeved on the outer wall of the vertical tube 31 and can move up and down along the vertical tube 31, and is used to support the handle end 21 of the upper expansion member 10, so as to fix the upper expansion member 10 in conjunction with the limiting stop 32.

[0076] Specifically, a limiting block 13 is provided on the opposite side wall of the handle end 21 of the upper dilator 10, and a push block 14 is provided on its outer wall. Thus, after inserting the upper dilator 10 and the dilating end 11 of the lower dilator 20 into the vagina and switching the upper dilator 10 to the second position, the push block 14 can be pushed upward with the thumb to move the lower dilator 20 upward to open the vagina. During the upward movement of the upper dilator 10, the limiting block 13 of the handle end 21 of the upper dilator 10 will move upward to between the two limiting edges 32 on the lower dilator 20, and will be blocked by the two limiting edges 32 and will not fall out of the handle end 21 of the lower dilator 20. At this time, the locking member 33 is rotated to move upward along the vertical tube 31 and support the handle end 21 of the upper dilator 10, so that the upper dilator 10 is kept in this position and will not move downward. Thus, the vagina can be kept in an open state for medical personnel to examine. In this embodiment, since the locking member 33 is threadedly connected to the vertical tube 31, the locking member 33 has a certain self-locking effect and will not move downward under the pressure of the upper expansion member 10. Therefore, the locking member 33 is easy to operate and has a good locking effect, which is beneficial to its use.

[0077] Advantageously, in another embodiment of the present invention, the locking member 33 is a circular ring structure.

[0078] The locking element 33 adopts a circular structure with no sharp edges, making it easy for medical staff to move it to drive it to rotate inside the lower expansion element 20 and thus adjust its position up and down.

[0079] Advantageously, in some embodiments of the present invention, the cleaning fluid supply assembly 40 includes a liquid outlet pipe 41 and a supply component 42; the vertical pipe 31 is provided with an inner channel 311, the liquid outlet pipe 41 is disposed in the expansion end 11 of the lower expansion component 20, and is provided with a first channel 411 inside, the first channel 411 being connected to the upper end of the inner channel 311.

[0080] The supply component 42 is located at the bottom of the lower expansion component 20 and is connected to the lower end of the inner channel 311 for supplying cleaning fluid.

[0081] Preferably, the liquid outlet pipe 41 is provided with a second channel 412 inside, and the vertical pipe 31 is provided with an outer channel 322 inside. The upper end of the outer channel 322 is connected to the second channel 412, and the lower end of the outer channel 322 is connected to a negative pressure extraction component.

[0082] In other words, both the vertical pipe 31 and the outlet pipe 41 are dual-channel. During use, the inner channel 311 of the vertical pipe 31 and the first channel 411 of the outlet pipe 41 can be used for the input of cleaning solution or medicine, while the outer channel 322 of the vertical pipe 31 and the second channel 412 of the outlet pipe 41 can be used for the discharge of waste liquid. In this way, the dual-channel input and discharge of waste liquid is conducive to the continuous input of clean medicine or cleaning solution.

[0083] It should be noted that the first channel 411 and the inner channel 311 need to have a small inner diameter so that the cleaning solution or medication can be sprayed into the vagina to clean or treat the patient's vagina. Furthermore, because the inner diameter of the first channel 411 is small, it also reduces the amount of waste fluid entering the first channel 411 and contaminating the passage.

[0084] Advantageously, in some other embodiments of the present invention, the handle end 21 of the lower expansion member 20 is provided with two connectors 50, one end of the two connectors 50 being connected to the inner channel 311 and the outer channel 322 respectively, and the other end of the two connectors 50 being detachably connected to the supply member 42 and the negative pressure extraction member respectively.

[0085] In other words, the supply component 42 for supplying cleaning fluid or medicine and the negative pressure extraction component for suctioning waste liquid can be detachably connected to the lower expansion component 20 via two connectors 50. This allows for disassembly and assembly according to usage requirements, which is beneficial for use. Specifically, the connectors 50 can be provided with internal threads, while the supply component 42 and the negative pressure extraction component are provided with external threads. Thus, the supply component 42 and the negative pressure extraction component can be threadedly connected to the connectors 50, which facilitates disassembly and assembly.
