Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a vaginal opening device for auxiliary cleaning in obstetrics and gynecology. Background Technology

[0002] In obstetrics and gynecology clinical diagnosis and treatment and daily care, vaginal cleaning is an important basic operation. Its core purpose is to remove secretions, residual drugs or pathogens from the vagina through precise cleaning, thereby reducing the risk of infection, assisting in the treatment of gynecological inflammation, or creating a good physiological environment for postoperative recovery. This type of operation requires first fully exposing the internal vaginal area, and then achieving targeted cleaning through professional cleaning methods. It is one of the key links to ensure the treatment effect of gynecological diseases and the reproductive health of patients.

[0003] The female vagina has a unique physiological structure, with an internal cavity and a fragile and sensitive mucosa. In addition, there are individual differences in the width and depth of the vagina among different patients, which places strict requirements on the safety and effectiveness of cleaning procedures.

[0004] The existing instruments lack precise coordination between the opening mechanism and the cleaning component. The cleaning component of some instruments is located off the central area of ​​the vagina, which makes it impossible for the cleaning solution to cover the inside of the vagina evenly, easily forming cleaning blind spots. At the same time, the adjustment of the opening range lacks a reliable limiting mechanism, making it difficult to accurately control the degree of opening according to individual patient differences. This may result in insufficient opening affecting the cleaning field of vision, or excessive opening damaging the vaginal mucosa. Summary of the Invention

[0005] The existing instruments lack precise coordination between the opening mechanism and the cleaning component. In some instruments, the cleaning component is positioned off-center from the vaginal center, resulting in the cleaning solution not being able to evenly cover the inside of the vagina, easily creating cleaning blind spots. At the same time, the adjustment of the opening range lacks a reliable limiting mechanism, making it difficult to accurately control the degree of opening according to individual patient differences. This may result in insufficient opening affecting the cleaning field of vision, or excessive opening damaging the vaginal mucosa. The purpose of this invention is to provide a vaginal opening device for auxiliary cleaning in obstetrics and gynecology.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A vaginal dilator for auxiliary cleaning in obstetrics and gynecology includes a base frame, on one side of which a dilator mechanism is provided. The dilator mechanism is used to be inserted into the patient's vagina to perform dilation.

[0008] The opening mechanism includes an adjustment plate with a limiting component, which is used to adjust the opening range of the opening mechanism; a cleaning component is provided on the other side of the base frame, which is located at the center of the base frame and is used to clean the inside of the patient's vagina.

[0009] Optionally, the spreading mechanism includes at least two movable slots formed on the base frame. A slider is slidably installed in the movable slot. A connecting plate is connected to the slider via a buffer assembly. A spreading plate is connected to the connecting plate via an adjustment assembly. A protruding post is fixedly installed on the slider. An adjustment plate is rotatably installed on the base frame. An arc-shaped groove is formed on the adjustment plate. The number of arc-shaped grooves is equal to the number of sliders and their positions correspond to each other. Each protruding post is slidably installed in the corresponding arc-shaped groove. The number of sliders is even and they are arranged symmetrically in pairs.

[0010] Optionally, a drainage groove is provided on the side of the expansion plate that contacts the patient's vaginal wall, and the drainage grooves are of several kinds and are equidistantly arranged along the length of the expansion plate.

[0011] Optionally, the buffer assembly includes a buffer groove formed on the connecting plate, one end of a buffer spring is fixedly installed in the buffer groove, the other end of the buffer spring is fixedly connected to a slider, and the slider is slidably connected to the inner wall of the buffer groove.

[0012] Optionally, the adjustment assembly includes adjustment slots formed on both sides of the expansion plate. The number of adjustment slots is several and they are evenly arranged in an array along the length direction of the expansion plate. A pair of inserts that cooperate with the adjustment slots are slidably installed on both sides of the connecting plate. The expansion plate passes through the connecting plate. A chamfer is provided at one end of the insert near the adjustment slot. A pair of return springs are fixedly installed on the insert. The other end of the return spring is fixedly connected to the connecting plate.

[0013] Optionally, the limiting component includes a lever fixedly mounted on the adjusting plate, a pin slidably mounted on the lever, a first sliding groove provided on the base frame, the lever sliding in the first sliding groove when the adjusting plate rotates, and a plurality of limiting holes cooperating with the pin provided on the base frame.

[0014] Optionally, the cleaning assembly includes a fixed rod fixedly mounted on a base frame, a positioning ring fixedly mounted on the fixed rod, a cleaning pipe whose movement mode is changed by a guide component inside the positioning ring, an annular nozzle fixedly mounted on the cleaning pipe, and an annular nozzle having an annularly arranged spray hole.

[0015] Optionally, a flow guide shroud is rotatably mounted on the annular nozzle, and the flow guide shroud has several inclined flow guide openings.

[0016] Optionally, the guide assembly includes a threaded groove formed on the cleaning pipe, a fixing plate is fixedly mounted on the positioning ring, and a threaded rod is threadedly connected to the fixing plate.

[0017] Optionally, the cleaning tube is provided with a connecting assembly, the connecting assembly including a rotating sleeve rotatably mounted on the cleaning tube, an inlet pipe fixedly connected to the rotating sleeve, the inlet pipe being connected to the cleaning tube through the rotating sleeve, a set of cavities being opened on the rotating sleeve, ball bearings being movably disposed in the cavities, the ball bearings being in rotatable contact with the wall of the cleaning tube.

[0018] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0019] In the above scheme, by setting up a spreading mechanism, when the adjusting disc rotates, the arc-shaped groove on its surface guides the protrusion on the slider. The curved trajectory of the arc-shaped groove converts the rotational motion of the adjusting disc into the sliding motion of the protrusion along the arc-shaped groove, thereby driving the slider to slide horizontally towards or away from each other in the movable groove of the base frame. The slider is connected to the connecting plate through a buffer assembly, and the connecting plate drives the spreading plate to move synchronously through the adjusting assembly. When the sliders slide away from each other, the spreading plate unfolds to both sides to spread the vaginal wall; when the sliders slide towards each other, the spreading plate retracts, facilitating the insertion or removal of the device. The smooth transmission of the arc-shaped groove and the protrusion allows for uniform movement of the spreading plate, avoiding excessive spreading speed that could cause patient discomfort. The movable groove limits the sliding direction of the slider, ensuring the precise movement trajectory of the spreading plate, avoiding excessive local compression caused by deviation, and controlling the degree of vaginal spreading.

[0020] By setting up a cleaning assembly, which uses a fixed rod and a positioning ring as the mounting base, the cleaning assembly provides support and guidance for the cleaning tube, ensuring that the cleaning tube moves along the axis of the base frame. After the cleaning tube is positioned by the guide assembly, its end ring nozzle extends into the vagina. External cleaning fluid is delivered to the ring nozzle through the cleaning tube, and then evenly sprayed out through the ring-shaped nozzle on the nozzle. The design of the ring nozzle allows the cleaning fluid to be sprayed in a ring-shaped covering pattern, which can act on all directions of the vaginal wall at the same time, avoiding cleaning blind spots.

[0040] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more comprehensive, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0041] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0042] Generally, terms can be understood at least partly from their use in context.

Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0043] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0044] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0045] like Figures 1 to 8As shown, this embodiment of the invention provides a vaginal dilatation device for gynecological and obstetric auxiliary cleaning, including a base frame 10. One end of the base frame 10 is provided with a dilatation mechanism 20, which is used to insert into the patient's vagina for dilatation. The dilatation mechanism 20 includes an adjustment plate 26 with a limiting component 50, which is used to adjust the dilatation range of the dilatation mechanism 20. A cleaning component 60 is disposed on the base frame 10 and located at the axis of the base frame 10, which is used to clean the inside of the patient's vagina.

[0046] The base frame 10 serves as the core support carrier of the entire device, providing an installation reference for the stretching mechanism 20 and the cleaning component 60, ensuring that the two are relatively fixed in position and work together. When in use, the stretching mechanism 20 is first aligned with the vaginal opening of the patient and slowly inserted into the vagina. The stretching mechanism 20 is driven by the operating adjustment plate 26 to achieve the stretching action of the vaginal wall. The limiting component 50 can limit the maximum stretching range of the stretching mechanism 20 during the stretching process to avoid damage to the vaginal mucosa due to excessive stretching.

[0047] Because the cleaning component 60 is located at the axis of the base frame 10, it can enter the vagina to rinse after the opening mechanism 20 is inserted into the vagina. After the opening mechanism 20 stably opens the vaginal wall and exposes the internal cleaning area, the cleaning component 60 delivers cleaning fluid into the vagina to complete the cleaning operation.

[0048] like Figures 1 to 5 As shown, the spreading mechanism 20 includes at least two movable slots 21 formed on the base frame 10. A slider 22 is slidably mounted within each movable slot 21. A connecting plate 23 is connected to the slider 22 via a buffer assembly 30. A spreading plate 24 is connected to the connecting plate 23 via an adjustment assembly 40. A protruding post 27 is fixedly mounted on the slider 22. The slider 22 and the connecting plate 23 are perpendicularly positioned. An adjusting disk 26 is rotatably mounted on the base frame 10. Multiple arc-shaped slots 28 are formed on the adjusting disk 26, and the protruding post 27 is slidably connected within each arc-shaped slot. The multiple arc-shaped slots 28 are evenly distributed in an array on the adjusting disk 26. In this embodiment, the number of movable slots 21 is even, and the movable slots 21 are arranged opposite each other and symmetrically.

[0049] When the adjusting disk 26 rotates, the arc-shaped groove 28 on its surface guides the protrusion 27 on the slider 22. The curved trajectory of the arc-shaped groove 28 converts the rotational motion of the adjusting disk 26 into the sliding motion of the protrusion 27 along the arc-shaped groove 28. Since the movable groove 21 and the supporting plate 24 are arranged opposite to each other, the slider 22 is driven to slide horizontally towards or away from each other in the movable groove 21 of the base frame 10. The slider 22 is connected to the connecting plate 23 through the buffer assembly 30. The connecting plate 23 then drives the supporting plate 24 to move synchronously through the adjusting assembly 40. When the slider 22 slides away from each other... When the device is in operation, the expansion plate 24 unfolds to both sides to open the vaginal wall; when the sliders 22 slide towards each other, the expansion plate 24 retracts, facilitating the insertion or removal of the device; the smooth transmission of the arc groove 28 and the protrusion 27 ensures uniform movement of the expansion plate 24, preventing discomfort to the patient caused by excessive expansion speed; the movable groove 21 limits the sliding direction of the sliders 22, ensuring accurate movement trajectory of the expansion plate 24 and preventing excessive local compression caused by deviation; the multi-stage connection structure of the sliders 22, connecting plate 23 and expansion plate 24 ensures uniform transmission of the opening force and improves the stability of the opening.

[0050] like Figures 4 to 5 As shown, a guide groove 25 is provided on the side of the expansion plate 24 that contacts the vaginal wall of the patient. There are several guide grooves 25, which are equidistantly arranged along the length of the expansion plate 24.

[0051] After the expansion plate 24 expands the vaginal wall, it fits tightly against the vaginal wall. When the cleaning fluid sprayed by the cleaning component 60 flows inside the vagina, some of the fluid tends to accumulate between the contact surface of the expansion plate 24 and the vaginal wall. The equidistant guide grooves 25 opened on the expansion plate 24 form a special fluid flow channel. The accumulated cleaning fluid can flow quickly along the guide grooves 25. On the one hand, it can flush the secretions and dirt on the surface of the vaginal wall to the outside of the vagina. On the other hand, it can avoid secondary pollution caused by the fluid staying on the contact surface for a long time.

[0052] like Figure 5As shown, the buffer assembly 30 includes a buffer groove 31 formed on the connecting plate 23. One end of a buffer spring 32 is fixedly installed in the buffer groove 31, and the other end of the buffer spring 32 is fixedly connected to the slider 22. The slider 22 is slidably connected to the inner wall of the buffer groove 31. The buffer assembly 30 achieves a buffering effect through the elastic deformation of the buffer spring 32. When the opening plate 24 contacts the vaginal wall and gradually opens, the vaginal wall will generate a reverse pressure on the opening plate 24. This pressure is transmitted to the buffer spring 32 in the buffer groove 31 through the connecting plate 23, causing the buffer spring 32 to undergo compression deformation. During the deformation process, the buffer spring 32 absorbs part of the reverse pressure, avoiding the direct rigid transmission of the opening force to the slider 22 and the adjusting plate 26. At the same time, it adjusts the pressure of the opening plate 24 on the vaginal wall through its own elastic restoring force. In addition, the sliding connection between the slider 22 and the inner wall of the buffer groove 31 ensures the stability of the movement trajectory of the connecting plate 23 during the buffering process and avoids deviation.

[0053] like Figures 5 to 6 As shown, the adjustment assembly 40 includes an adjustment groove 41 formed on the support plate 24. The number of adjustment grooves 41 is multiple and they are evenly arranged in an array along the length direction of the support plate 24 on the side wall of the support plate 24. A pair of inserts 43 corresponding to the adjustment grooves 41 are slidably installed on both sides of the connecting plate 23. A pair of chamfers are provided at one end of the insert 43 near the adjustment groove 41. A pair of return springs 42 are fixedly installed on the insert 43. The other end of the return springs 42 is fixedly connected to the connecting plate 23.

[0054] The adjustment component 40 adjusts the position of the expansion plate 24 by engaging the insertion block 43 with the adjustment groove 41, thus adapting to different vaginal depth and width requirements. When it is necessary to adjust the extension length of the expansion plate 24, the insertion block 43 is pulled to both sides. The insertion block 43 stretches the return spring 42 and slides away from the connecting plate 23, disengaging the insertion block 43 from the adjustment groove 41 on the expansion plate 24. At this time, the expansion plate 24 can be pushed to adjust its position. The expansion plate 24 is slidably connected to the bottom inner wall of the connecting plate 23, that is, the expansion plate 24 passes through the bottom of the connecting plate 23. After adjusting to the appropriate position, the insertion block 43 is released. The return spring 42 pulls the insertion block 43 back to its original position under the action of elastic restoring force. The insertion block 43 is smoothly inserted into the corresponding adjustment groove 41 through the guiding action of the guide angle, thus locking the position of the expansion plate 24. The design of the guide angle reduces the difficulty of aligning the insertion block 43 with the adjustment groove 41, making the adjustment operation smoother.

[0055] like Figures 1 to 2As shown, the limiting component 50 includes a lever 51 fixedly mounted on the adjusting plate 26, a pin 52 slidably mounted on the lever 51, and multiple limiting holes 53 on the base frame 10 that cooperate with the pin 52. The limiting component 50 fixes the rotation angle of the adjusting plate 26 by engaging the pin 52 with the limiting holes 53, thereby limiting the opening range of the opening mechanism 20. When the adjusting plate 26 is rotated and the opening plate 24 is opened to a suitable angle, the pin 52 on the lever 51 is pushed so that the pin 52 is inserted into the corresponding limiting hole 53 on the base frame 10. At this time, the adjusting plate 26 is locked and cannot continue to rotate, and the opening angle of the opening plate 24 remains stable. When it is necessary to adjust the opening angle, the pin 52 is pulled to disengage from the limiting hole 53, and the adjusting plate 26 regains its rotational freedom. The adjusting plate 26 can be rotated to adjust the opening degree. The multiple limiting holes 53 on the base frame 10 correspond to different opening angles to meet the needs of different cleaning scenarios.

[0056] like Figures 1 to 8 As shown, the cleaning assembly 60 includes a fixed rod 61 fixedly installed on the base frame 10. A positioning ring 62 is fixedly installed on the fixed rod 61. A cleaning pipe 63 with its movement mode changed by a guide assembly 70 is provided inside the positioning ring 62. An annular nozzle 64 is fixedly installed at one end of the cleaning pipe 63. The annular nozzle 64 has an annularly arranged nozzle 65.

[0057] The cleaning assembly 60 is mounted on a fixed rod 61 and a positioning ring 62. The positioning ring 62 provides support and guidance for the cleaning tube 63. The positioning ring 62 is coaxially set with the base frame 10 to ensure that the cleaning tube 63 moves along the axis of the base frame 10. After the cleaning tube 63 is adjusted in position by the guide assembly 70, the annular nozzle 64 at its end extends into the vagina. The external cleaning fluid is delivered to the annular nozzle 64 through the cleaning tube 63 and then evenly sprayed out through the annular nozzle 65 on the nozzle. The design of the annular nozzle 65 makes the cleaning fluid sprayed in an annular covering shape, which can act on all directions of the vaginal wall at the same time and avoid cleaning blind spots.

[0058] like Figure 7 As shown, a flow guide 66 is rotatably mounted on the annular nozzle 64. The flow guide 66 has several inclined flow guide openings. The flow guide 66 on the annular nozzle 64 can rotate around the nozzle. By adjusting the angle of the flow guide 66, the inclined flow guide openings on its surface can change the spray direction and angle of the cleaning fluid. When the cleaning fluid is sprayed out from the annular nozzle 65, it will hit the inner wall of the flow guide 66 and then be refracted and sprayed in a designated direction through the inclined flow guide openings. When the flow guide 66 is rotated, the inclined direction of the flow guide openings changes synchronously, which can realize multi-angle and multi-directional flushing of the cleaning fluid inside the vagina. It can both focus on cleaning specific areas and achieve comprehensive coverage cleaning.

[0059] The guide assembly 70 includes a threaded groove 71 formed on the cleaning pipe 63. A fixing plate 73 is fixedly installed on the positioning ring 62, and a threaded rod 72 is threadedly connected to the fixing plate 73. When the threaded rod 72 is not in contact with the threaded groove 71, the cleaning pipe 63 can move linearly along the axial direction to cooperate with the annular nozzle 64 to complete the cleaning. When the threaded rod 72 is rotated to enter the threaded groove 71, the cleaning pipe 63 is guided by the threaded groove 71 to rotate during the movement, which drives the annular nozzle 64 to rotate together, improving the cleaning effect and avoiding the existence of cleaning dead corners.

[0060] like Figure 8 As shown, a connecting component 80 is provided on the cleaning tube 63. The connecting component 80 includes a rotating sleeve 81 rotatably mounted on the cleaning tube 63. An inlet pipe 84 is fixedly mounted on the rotating sleeve 81 and communicates with the cleaning tube 63. A set of cavities 82 is opened on the rotating sleeve 81, and ball bearings 83 are movably arranged in the cavities 82.

[0061] The connecting component 80 is used to connect the cleaning tube 63 to the external cleaning fluid supply device, and also solves the problem of the inlet tube 84 getting tangled when the cleaning tube 63 moves axially. The rotating sleeve 81 is rotatably connected to the cleaning tube 63 through the ball bearings 83 in the cavity 82. The ball bearings 83 reduce the frictional resistance between the rotating sleeve 81 and the cleaning tube 63, allowing the rotating sleeve 81 to rotate flexibly around the cleaning tube 63. The external inlet tube 84 is fixed on the rotating sleeve 81. When the cleaning tube 63 extends or retracts axially, the rotating sleeve 81 can rotate synchronously because the cavity 82 is embedded in the wall of the cleaning tube 63, ensuring that the inlet tube 84 always remains smoothly connected and will not twist, get tangled, or fall off due to the movement of the cleaning tube 63. The cavity 82 provides installation and movement space for the ball bearings 83, ensuring smooth rolling of the ball bearings 83.

[0062] The specific workflow of the technical solution provided by this invention is as follows:

[0063] Medical staff first adjust the extension length of the spreading plate 24 according to the condition of the patient's vagina by adjusting component 40; then adjust the initial insertion depth of the cleaning tube 63 by guiding component 70; and finally connect the external cleaning fluid supply device to the cleaning tube 63 by connecting component 80.

[0064] After the patient assumes a suitable position, the medical staff holds the base frame 10, applies lubricant to the folded expansion plate 24, and slowly inserts it into the patient's vagina. They rotate the adjustment disc 26 on the base frame 10, causing the arc-shaped groove 28 on the adjustment disc 26 to slide the protrusion 27 on the slider 22, allowing the slider 22 to slide back-to-back along the movable groove 21 of the base frame 10. The slider 22, through the buffer assembly 30, causes the connecting plate 23 and the expansion plate 24 to unfold (the buffer spring 32 absorbs the reverse pressure of the vaginal wall, avoiding rigid impact). When the expansion plate 24 is opened to a suitable angle, fully exposing the clean area inside the vagina, the staff pushes the pin 52 on the lever 51, inserting it into the corresponding limiting hole 53 on the base frame 10, locking the adjustment disc 26 to ensure a stable opening angle. At this time, the guide groove 25 on the expansion plate 24 forms a liquid flow channel with the vaginal wall, preparing for subsequent cleaning fluid flow.

[0065] When the external cleaning solution supply device is activated, the cleaning solution enters the rotating sleeve 81 through the inlet pipe 84, then flows into the cleaning pipe 63, and is finally delivered to the annular nozzle 64. After the cleaning solution is sprayed out from the annular nozzle 65 on the annular nozzle 64, it hits the inner wall of the guide shroud 66 and is refracted and sprayed in all directions of the vaginal wall through the inclined guide opening on the guide shroud 66. Medical staff can rotate the guide shroud 66 to adjust the spray angle of the cleaning solution according to the cleaning needs (focusing on cleaning areas where dirt accumulates), so as to achieve all-round, no dead angle cleaning of the vaginal interior.

[0066] After cleaning, first turn off the cleaning solution supply device, pull the pin 52 of the limiting component 50 to disengage from the limiting hole 53, rotate the adjusting plate 26 in the opposite direction to make the slider 22 slide towards each other, and retract the spreading plate 24. Slowly pull the device out of the patient's vagina, and finally disassemble the connection between the connecting component 80 and the external device, and clean and disinfect the device.

[0067] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
