Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field especially relates to a vagina dilator. BACKGROUND

[0002] The medical vagina dilator is a kind of medical instrument for gynecological examination and treatment, mainly used for observing and examining vagina and cervix uteri. By dilating the vagina wall, doctors can clearly view the internal structure of cervix uteri and vagina, and carry out diagnosis and treatment. In clinical practice, when gynecological examination is carried out on patients with pelvic organ prolapse, the operator needs to assess the length of the anterior and posterior walls of the patient's vagina and the distance between the specific point and the hymen, and also needs to measure the length of the vagina, genital hiatus and perineal body. However, since the currently used vagina dilator has no scale display, subjective estimation method is often used to measure the length of the anterior and posterior walls of the patient's vagina, or disposable ruler is used for auxiliary measurement, which has a large error. In addition, the vagina dilator is used to expand the vaginal orifice during examination, so that the cervix uteri is fully exposed for operation. However, for some patients with excessively deep vagina, the operator needs to slightly force the vagina dilator into the patient's body to fully expose the field of view, which causes the rear end of the vagina dilator to enter the patient's vulva, resulting in poor comfort of the patient and greatly reducing the patient's use experience. At the same time, for patients with pelvic organ prolapse, the vagina wall is loose, and during gynecological examination, the vagina side wall will flow into the middle of the two blades, blocking the observation field of view. Therefore, the vagina dilator needs to be continuously rotated or repeatedly placed to complete the exposure, which causes pain to the patient.

[0003] The vagina dilator disclosed in the patent application file with publication number CN115702972A includes an upper support, a lower support, a screw rod and a nut.

DETAILED DESCRIPTION

[0024] In order to make those skilled in the art better understand the technical scheme of the utility model, the technical scheme of the utility model is further described below in combination with the drawings and examples.

[0025] Example one:

[0026] Example one provides a kind of vaginal dilator, as shown in Figure 1, it includes first blade 1, second blade 11, scale line 2, contact lubrication assembly 3, lubrication groove 301, flow guide groove 302, silica gel soft head 303, inlet 304, first connecting handle 4, second connecting handle 5, second positioning block 6, screw rod 7, fixed plate 8, movable groove 801 and first positioning block 802. Figures 1-5The vaginal dilator includes a first leaf 1 and a second leaf 11, both of which are arc-shaped structures made of medical plastic material and can be inserted into the patient's vagina, and a gap is left between the first leaf 1 and the second leaf 11 for easy viewing of the patient's vagina. The rear end of the first leaf 1 and the second leaf 11 is movably connected, so that the angle between the first leaf 1 and the second leaf 11 can be adjusted. The inner side of the first leaf 1 and the second leaf 11 is provided with a scale line 2. The front leaf and the rear leaf of the first leaf 1 and the second leaf 11 are each increased by 1cm to meet the use requirements of patients with pelvic organ prolapse or vaginal relaxation, reduce the discomfort of patients caused by insufficient exposure of the vagina, repeated opening and closing of the leaves and rotation, the length of the front leaf is 9cm, the length of the rear leaf is 8cm, and the length of the outer opening is 4.5cm. When in use, the depth of the first leaf 1 and the second leaf 11 inserted into the patient's vagina can be quickly and intuitively seen through the scale line 2 on the inner side of the first leaf 1 and the second leaf 11.

[0027] The outer side of the first leaf 1 and the second leaf 11 is provided with a contact lubricating assembly 3, the contact lubricating assembly 3 includes a plurality of lubricating grooves 301 opened on the outer side of the first leaf 1 and the second leaf 11, the plurality of lubricating grooves 301 on the first leaf 1 are in communication with each other, the plurality of lubricating grooves 301 on the second leaf 11 are also in communication with each other, and the inner side of the first leaf 1 and the second leaf 11 is provided with an injection port 304, the injection port 304 is in communication with the plurality of lubricating grooves 301 corresponding to each other, and the injection port 304 can be used to inject lubricating liquid into the plurality of lubricating grooves 301, and the lubricating liquid flows to the outer surface of the first leaf 1 and the second leaf 11 through the corresponding lubricating grooves 301, thereby reducing friction and discomfort when the first leaf 1 and the second leaf 11 are inserted and taken out, not only improving the comfort of the first leaf 1 and the second leaf 11 in use, but also helping to protect the sensitive tissues of the patient and reduce the irritation or injury caused by operation.

[0028] The contact lubricating assembly 3 further includes a plurality of flow guide grooves 302 opened in the lubricating grooves 301, and the plurality of flow guide grooves 302 are obliquely arranged, which can more effectively guide the lubricating liquid into the lubricating grooves 301 of the first leaf 1 and the second leaf 11, and ensure that the lubricating liquid is evenly distributed on the outer surface of the first leaf 1 and the second leaf 11.

[0029] The front end of the first leaf 1 and the second leaf 11 is fixedly connected with a silica gel soft head 303, and the silica gel soft head 303 is arranged in a semicircular shape, which can preferentially contact the vaginal orifice through the silica gel soft head 303 at the front end of the first leaf 1 and the second leaf 11, thereby reducing the discomfort when the first leaf 1 and the second leaf 11 are contacted, and the two semicircular silica gel soft heads 303 can more conveniently open the vaginal orifice and put the first leaf 1 and the second leaf 11.

[0030] Preferably, the width of the first blade 1 and the second blade 11 can be set to 3cm, 3.5cm, 4cm or 4.5cm. The size of the dilator can be adjusted according to the size of the genital slit in patients with pelvic organ prolapse, so as to effectively expose the vagina and cervix and prevent the vaginal sidewalls from rushing in from both sides during the dilation period and obstructing the field of vision.

[0031] The vaginal speculum in this embodiment is used for gynecological examinations of patients. When in use, the silicone soft head 303 at the front end of the first blade 1 and the second blade 11 is preferentially brought into contact with the vaginal opening of the patient, thereby reducing the discomfort when the first blade 1 and the second blade 11 come into contact. Moreover, the two semi-circular silicone soft heads 303 can make it easier to open the vaginal opening and insert the first blade 1 and the second blade 11.

[0032] Lubricant is then injected through the injection port 304. The lubricant flows through the corresponding lubrication groove 301 to the outer surfaces of the first blade 1 and the second blade 11, thereby reducing friction and discomfort when inserting and removing the first blade 1 and the second blade 11. This not only improves the comfort of using the first blade 1 and the second blade 11, but also helps protect the patient's sensitive tissues and reduces stimulation or injury caused by the operation. The oblique setting of the guide groove 302 can more effectively guide the lubricant into the lubrication groove 301 of the first blade 1 and the second blade 11, ensuring that the lubricant is evenly distributed on the outer surfaces of the first blade 1 and the second blade 11. It should be noted that in gynecological examinations that require sampling of vaginal secretions or where other lubricants may affect the examination results, lubricant should not be injected when inserting the vaginal speculum into the vagina. Lubricant should be injected through the injection port 304 after the examination or sampling is completed to facilitate the removal of the vaginal speculum.

[0033] When the vaginal speculum is inserted into the patient's vagina, the depth of insertion can be directly observed by looking at the scale lines on the inner side of the first blade 1 and the second blade 11. This helps to measure the distance between the cervix and the posterior fornix of the vagina and the hymen. The widened design of the first and second blades can increase the support of the anterior and posterior vaginal walls in patients with vaginal laxity or pelvic organ prolapse, preventing the vaginal side walls from entering. Examination and sampling can be performed through the gap between the first blade 1 and the second blade 11.

[0034] If the first blade 1 and the second blade 11 need to be separated, the second blade 11 can be squeezed inward to separate it from the first blade 1. The second blade 11 can then be taken out and used as a ruler for corresponding measurements.

[0035] Example 2:

[0036] On the basis of the first leaf 1 and the second leaf 11, in order to facilitate the adjustment of the angle between the first leaf 1 and the second leaf 11, facilitate the operation of the first leaf 1 and the second leaf 11, two first connecting handles 4 are symmetrically arranged on both sides of the rear end of the first leaf 1, and the two first connecting handles 4 form a complete structure with the first leaf 1, two second connecting handles 5 are symmetrically arranged on both sides of the rear end of the second leaf 11, and the two second connecting handles 5 form a whole structure with the second leaf 11. Two second connecting handles 5 are respectively located inside the corresponding first connecting handle 4, and each second connecting handle 5 is respectively connected with the corresponding first connecting handle 4 (specifically, a small protrusion is arranged on the second connecting handle 5, and a small groove is arranged on the first connecting handle 4, so that the first connecting handle 4 and the second connecting handle 5 are connected, and when the second connecting handle 5 is pressed inward, the first connecting handle 4 and the second connecting handle can be separated), by rotating the second connecting handle 5, the angle between the first leaf 1 and the second leaf 11 can be adjusted. A connecting assembly for angle adjustment and limiting is arranged between the first connecting handle 4 and the second connecting handle 5.

[0037] More specifically, the connecting assembly includes a second positioning block 6 fixedly arranged between the two second connecting handles 5, and a fixed sheet 8 fixedly arranged between the two first connecting handles 4, the fixed sheet 8 is provided with a movable groove 801, and the first positioning block 802 is movably connected in the movable groove 801, the first positioning block 802 can slide in the movable groove 801 and can be flipped up and down, so that when the first positioning block 6 changes the angle with the second leaf 11, the axis of the first positioning block 802 and the second positioning block 6 can be located on the same straight line. The first positioning block 802 is threadedly connected with a screw rod, and the end of the screw rod 7 away from the first positioning block 802 is also threadedly connected with the second positioning block 6.

[0038] When it is necessary to adjust the angle between the first leaf 1 and the second leaf 11, first rotate the screw rod 7 to separate the screw rod 7 from the second positioning block 6, then adjust the angle between the first leaf 1 and the second leaf 11 through the second connecting handle 5, move the position of the first positioning block 802 after the angle is adjusted, and rotate the screw rod 7 and the first positioning block 802 as a whole, rotate the screw rod 7 to threadedly connect it with the second positioning block 6, so as to limit the angle of the second connecting handle 5, and ensure that the angle between the first leaf 1 and the second leaf 11 is stable and unchanged.
