Description

Technical Field

[0001] The present invention relates to the technical field of gynecological examination instruments, and particularly to a vaginal dilator. Background Art

[0002] A vaginal dilator is a commonly used medical device for examining gynecological diseases. Traditional duckbill-shaped vaginal dilators mostly have a two-wing structure. In order to improve the dilation effect of the dilator without changing the doctor's usage habits, dilators with a two-wing structure have been improved to a four-wing structure on the market. For existing four-wing structure dilators, there is no linkage structure between the upper and lower wings and the left and right wings. During the operation, it is necessary to first open the upper and lower wings, and then open the left and right wings. In other words, the four wings of the dilator cannot be expanded synchronously, so it is inconvenient for doctors during use and will also cause discomfort to the examinee. Summary of the Invention

The visible module of the visible mechanism 8 is opposite to the visible area 1121, and the visible mechanism 8 observes the vagina through the visible area 1121.

[0038] See Figure 6 , the first expansion member 2 includes a first expansion portion 21, a first expansion connecting portion 22, and a first expansion driving portion 23. The number of the first expansion connecting portions 22 is two. The two first expansion connecting portions 22 connect the first expansion portion 21 and the first expansion driving portion 23, and the two first expansion connecting portions 22 are hinged to the two mounting portions 12 one by one. Pressing the first expansion driving portion 23 can drive the first expansion portion 21 to rotate. In addition, the first expansion member 2 further includes two first expansion transmission portions 24. The two first expansion transmission portions 24 are connected to the first expansion driving portion 23 and are used to drive the side expansion member 4.

[0039] The second expansion member 3 and the first expansion member 2 are arranged up and down, and the second expansion member 3 is connected to the first expansion member 2 through a first linkage mechanism 5. Driving the first expansion member 2 to rotate can drive the second expansion member 3 to rotate synchronously. Specifically, the second expansion member 3 includes a second expansion portion 31 and two second expansion connecting portions 32. The two second expansion connecting portions 32 are symmetrically arranged on the second expansion portion 31. The two second expansion connecting portions 32 are hinged to the two mounting portions 12 one by one, and at least one second expansion connecting portion 32 is connected to the adjacent first expansion connecting portion 22 through the first linkage mechanism 5. Preferably, the number of the first linkage mechanisms 5 is two groups, and the two groups of first linkage mechanisms 5 are symmetrically arranged. The two second expansion connecting portions 32 are connected to the two first expansion connecting portions 22 through the two groups of first linkage mechanisms 5. The second expansion connecting portion 32 is connected to the first expansion connecting portion 22 on the same side through the first linkage mechanism 5, improving the linkage stability between the first expansion member 2 and the second expansion member 3.

[0040] Further, seeFigure 7 , the first linkage mechanism 5 includes a first link member 51 and a second link member 52. One end of the first link member 51 is hinged to the first expansion connection portion 22, the other end of the first link member 51 is hinged to one end of the second link member 52, the other end of the second link member 52 is hinged to the second expansion connection portion 32, and the rotation connection point of the first link member 51 and the second link member 52 is movably arranged on the mounting portion 12.

[0041] Furthermore, a first linkage travel position 121 is provided on the mounting portion 12. The rotation connection point of the first link member 51 and the second link member 52 is movably arranged in the first linkage travel position 121, and the rotation connection point of the first link member 51 and the second link member 52 moves along the first linkage travel position 121. In this embodiment, the first linkage travel position 121 is an oval hole.

[0042] The two side expansion members 4 are arranged left and right and are located between the first expansion portion 21 and the second expansion portion 31. The side expansion members 4 are respectively connected to the first expansion member 2 through the second linkage mechanism 6. Driving the first expansion member 2 to rotate can drive the side expansion members 4 to rotate synchronously. Specifically, the side expansion member 4 includes a side expansion portion 41 and a side expansion connection portion 42. The side expansion connection portion 42 is connected to the side expansion portion 41 and is hinged to the mounting portion 12 on the same side. Among them, a rotating shaft 122 is respectively provided on the mounting portion 12, and the side expansion connection portion 42 is rotatably sleeved with the rotating shaft 122 on the same side. At the same time, the side expansion connection portion 42 is connected to the first expansion connection portion 22 on the same side through the second linkage mechanism 6.

[0043] Furthermore, the second linkage mechanism 6 includes a first pull rod member 61 and a second pull rod member 62. One end of the first pull rod member 61 is rotatably sleeved with the side expansion connection portion 42 on the same side. The other end of the first pull rod member 61 is rotatably connected to one end of the second pull rod member 62. The first expansion is movably arranged on the other end of the second pull rod member 62, and the second pull rod member 62 is movably arranged on the handheld member 1.

[0044] Furthermore, a guide groove 123 is provided on the mounting portion 12, and a guide bar 621 is provided on the second pull rod member 62. The guide bar 621 is movably arranged in the guide groove 123, and the guide bar 621 moves along the guide groove 123 to guide the moving direction of the second pull rod member 62.

[0045] Furthermore, support bars 124 are respectively provided on the handheld portion 11 facing the mounting portion 12. The support bars 124 are used to support the second pull rod member 62.

[0046] Further, a second linkage travel position 622 is provided at one end of the second pull rod member 62 away from the first pull rod member 61. The first expansion transmission part 24 is movably connected to the second linkage travel position 622. Through the cooperation of the first expansion transmission part 24 and the second linkage travel position 622, the first expansion member 2 drives the second pull rod member 62 to move.

[0047] Preferably, a limiting position 13 is provided between the installation part 12 and the visible section 112. One end of the second pull rod member 62 close to the first pull rod member 61 movably passes through the limiting position 13, and the end of the second pull rod member 62 away from the first pull rod member 61 cannot pass through the limiting position 13, thereby restricting the moving stroke of the second pull rod member 62 and also restricting the moving direction of the second pull rod member 62.

[0048] During specific application: Install the visual mechanism 8 in the installation cavity 113, hold the holding section 111 of the holding part 11 and press the first expansion driving part 23. Through the transmission of the first expansion connecting part 22, the first expansion part 21 rotates upward, and the first expansion connecting part 22 drives the first link member 51 and the second link member 52 to move, and then drives the second expansion connecting part 32 to rotate downward, that is, drives the second expansion part 31 to rotate downward; at the same time, when pressing the first expansion driving part 23, the first expansion transmission part 24 is driven to move, so as to drive the first pull rod member 61 and the second pull rod member 62 to move, and then drive the side expansion connecting part 42 to rotate outward, that is, drive the side expansion part 41 to rotate outward. At this time, the dilator is in the open state, and an open channel is formed between the first expansion member 2, the second expansion member 3 and the two side expansion members 4. The visual mechanism 8 can observe the vagina through the open channel. Conversely, releasing the first expansion driving part 23 can close the dilator.

[0049] In addition, the vaginal dilator further includes a locking mechanism 7, and the position of the first expansion member 2 is relatively fixed through the locking mechanism 7, and then the positions of the second expansion member 3 and the two side expansion members 4 are relatively fixed.

[0050] The locking structure includes a locking part 71 and a locking position 72. One end of the locking part 71 is provided on the hand-held part 1, the other end of the locking part 71 is suspended and passes through the locking position 72, the locking position 72 is provided on the first expansion member 2, and the locking part 71 is detachably connected to the locking position 72.

[0051] Further, locking teeth 711 are provided on the locking part 71, locking teeth 721 are provided on the locking position 72, and the locking teeth 711 are engaged with the locking teeth 721 to relatively fix the first expansion member 2. The locking part 71 is arranged along the flipping path of the first expansion member 2, and the number of the locking teeth 711 is multiple, and the multiple locking teeth 711 are arranged along the locking part 71 to realize the fixation of multiple opening angles of the dilator.

[0052] Further, a locking driving part 712 is provided on the suspended end of the locking part 71. Pushing the locking driving part 712 can bend the locking part 71 by a certain angle, separating the locking teeth 711 from the locking teeth 721, and the first expander 2 is in an active state.

[0053] In summary, the second expander of the vaginal dilator is connected to the first expander through the first linkage mechanism. At the same time, the two side expanders are connected to the first expander through the second linkage mechanism. When driving the first expander to flip, it can drive the second expander and the two side expanders to flip synchronously, and the expansion operation can be completed in one step, realizing the synchronous expansion of the four wings, greatly improving the convenience of use and reducing the discomfort of the examinee.
