Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a vaginal dilator. Background Art

[0002] Cervical disease has always been one of the most common diseases in clinical gynecology, seriously affecting women's physical health and quality of life. Taking the initiative to check regularly and seek medical treatment in time when symptoms of cervical disease appear are the keys to preventing and treating cervical disease. At present, hospitals generally use vaginal dilators to collect samples from the inner wall of the vagina or cervix of women in order to provide data for the next step of examination or treatment.

[0003] However, in the prior art, when inserting the dilator into the female vagina to observe the vaginal environment, the screw needs to be rotated so that the upper and lower leaves can be locked. However, since the screw on the existing vaginal dilator is long and faces the operating doctor, it is not convenient for the doctor to operate it during use. On the other hand, the locking of the screw can only make the expanded upper and lower leaves no longer close to each other, and cannot make them move away from each other again. At this time, once the operating doctor accidentally touches the handle, it is easy to cause the upper and lower leaves to expand again, which will cause pain to the patient and is inconvenient to use. Therefore, it is urgently needed to be improved. Utility Model Content

[0030] See also Figure 1-Figure 6 , a vaginal dilator comprising:

[0031] A lower connecting member 1 and an upper connecting member 2; wherein,

[0032] The lower connecting member 1 includes a first handle portion 101 and a lower leaf 102, and the first handle portion 101 and the lower leaf 102 are connected via a first bending member 103;

[0033] The upper connecting member 2 includes a second handle portion 201 and an upper leaf 202, and the second handle portion 201 and the upper leaf 202 are connected via a second bending member 203;

[0034] A through hole 104 is formed on the side of the first bending member 103; the second bending member 203 is sleeved on the outside of the first bending member 103, and a rotating shaft 3 is fixed on the second bending member 203, the rotating shaft 3 passes through the through hole 104 and extends to the inside of the first bending member 103, and a gear 4 is sleeved on the rotating shaft 3 located inside the first bending member 103;

[0035] A locking assembly for locking the gear 4 is disposed at one end of the first handle portion 101 facing the second handle portion 201 .

[0036] Furthermore, the locking assembly includes a screw rod 8, a connecting plate 7 and a locking block 10; the locking block 10 is provided with a locking tooth 11 meshing with the gear 4; the interior of the first handle portion 101 is a hollow structure, one end of the screw rod 8 passes through the interior of the first handle portion 101 and is connected to the first handle portion 101 by a thread, and the other end of the screw rod 8 is provided with a handle 9; the bottom of the locking block 10 is connected to the connecting plate 7, and the connecting plate 7 is provided with a clearance hole 12 for the screw rod 8 to pass through;

[0037] Because the angle between the upper connecting member 2 and the lower connecting member 1 can be adjusted under the action of the rotating shaft 3, the patient's vagina can be stretched open by rotating the two to a certain angle; when stretched to a specified size, the screw rod 8 is rotated to move toward the inside of the first handle portion 101, thereby driving the connecting plate 7 to move, and the connecting plate 7 drives the locking block 10 to move so that the locking teeth 11 on the locking block 10 can mesh with the gear 4, thereby locking the gear 4 at this time, thereby completing the angle adjustment between the upper connecting member 2 and the lower connecting member 1;

[0038] The advantage of such a design is that, by placing the screw rod 8 between the first handle portion 101 and the second handle portion 201, when the angle needs to be adjusted or locked, it is only necessary to rotate the screw rod 8 to move the locking block 10 away from or close to the gear 4. At the same time, since the gear 4 on the rotating shaft 3 is locked, the forward and backward movement distance of the entire locking block 10 does not need to be too long, that is, the screw rod 8 does not need to be too long, so that the entire locking assembly occupies a small space and is not easily touched by mistake by the operating doctor; at the same time, by locking the gear 4, a two-way locking between the upper connecting member 2 and the lower connecting member 1 can be achieved, and the locking effect is good, thereby avoiding the risk of further expansion of the patient's vagina.

[0039] Furthermore, the plug plate 6 is connected to one end of the connecting plate 7 facing the first handle portion 101, and a plug hole 5 for the plug plate 6 to pass through and slide is provided on one side of the first handle portion 101 facing the connecting plate 7;

[0040] By sliding the plug plate 6 inside the plug hole 5, the movement of the entire connecting plate 7 is made more stable, thereby ensuring the locking effect of the locking block 10 on the gear 4 and improving the use effect.

[0041] Furthermore, the top of the connecting plate 7 is also provided with friction linings 13 located on both sides of the locking block 10, and one end of the friction lining 13 facing the rotating shaft 3 is provided with an arc surface adapted to the outer wall of the rotating shaft 3;

[0042] The friction lining 13 is made of a non-slip material, such as rubber. When the locking block 10 locks the gear 4, the arc surface on the friction lining 13 will come into close contact with the outer wall of the shaft 3, thereby further braking the shaft 3 to enhance the locking effect.

[0043] Furthermore, a plurality of elastic balls 14 are arranged in a circumferential array on one end of the handle 9 facing the connecting plate 7, and the elastic balls 14 are made of silicone.

[0044] When the locking block 10 locks the gear 4 , the connecting plate 7 will be attached to the end surface of the first handle portion 101 , and the elastic ball 14 on the handle 9 will be tightly attached to the end surface of the connecting plate 7 , thereby ensuring the locking effect of the screw 8 .

[0045] Furthermore, a mounting plate 15 is provided at one end of the second handle portion 201 away from the first handle portion 101, and a connecting block 16 is provided on the top of the mounting plate 15, a ball shaft 17 is embedded on the top of the connecting block 16, and a fixing clip 18 is connected to the ball shaft 17, and a searchlight 19 is provided in the fixing clip 18;

[0046] The mounting plate 15 and the second handle portion 201 can be detachably connected by bolts, and after the searchlight 19 is clamped in the fixing clamp 18, the searchlight 19 can be adjusted to a certain angle under the action of the ball shaft 17, so that the searchlight 19 can be used to provide lighting brightness to the patient's vagina.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
