Description

Technical Field

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

[0002] A vaginal dilator, also known as a speculum, is a medical device composed of two upper and lower dilating blades and a handle. It is mainly used for routine gynecological examinations to help doctors clearly observe the conditions of the cervix and vaginal wall, facilitating the collection of samples such as cervical smears. It is used in gynecological surgeries to help expand the field of view for easy operation. In some cases, it is used for postpartum recovery to prevent vaginal adhesions and stenosis and improve the quality of life after surgery.

[0003] In the field of gynecological examinations and treatments, the vaginal dilator, as a key medical tool, mainly functions to help doctors clearly observe the conditions of the cervix and vaginal wall. However, common vaginal dilators on the market currently have some design deficiencies. When the dilator is opened inside the patient's body, due to structural limitations, it is easy for the tissues of the vaginal inner wall to fill into the dilator. This phenomenon not only hinders the doctor's direct observation of the target area but also may affect the accuracy and comprehensiveness of the examination, increasing the difficulty of diagnosis. In addition, this design defect may lead to the inability to obtain sufficient visual information in some complex cases to make accurate judgments, thus affecting the treatment effect of patients. Summary of the Invention

[0004] The purpose of the present invention is to provide a gynecological vaginal dilator to solve the problem that when the existing vaginal dilator is opened and used inside the patient's vagina, it is easy for the tissue structure of the vaginal inner wall to fill into the dilator, thus affecting the observation field of view as mentioned in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A gynecological vaginal dilator, comprising:

[0007] A mounting plate;

[0008] An adjusting mechanism, which is arranged outside the mounting plate;

[0009] A dilating mechanism, which is installed outside the mounting plate;

[0010] A pressing plate, which is sleeved outside the mounting plate;

[0011] A shielding mechanism, which is arranged on the inner side wall of the dilating mechanism. The shielding mechanism includes a mounting seat, a rotating gear, and a rack plate. The outside of the mounting seat is rotatably connected with a rotating gear, the outside of the rotating gear is engaged with a rack plate, and the outside of the rack plate is fixedly connected with a shielding plate.

[0012] Preferably, two sets of rack plates are arranged on the bottom surface of the shielding plate, two shielding plates are symmetrically arranged inside the expansion mechanism, and the shielding plate is an arc-shaped stainless steel plate.

[0013] Preferably, a mating mechanism is installed outside the pressing plate, and a rotating mechanism is installed on one side of the shielding mechanism.

[0014] Preferably, the adjusting mechanism includes an adjusting groove, a first threaded rod, and a first adjusting nut seat. The adjusting groove is opened outside the mounting plate, the first threaded rod is inserted into the adjusting groove, and the first adjusting nut seat is sleeved on the outside of the first threaded rod.

[0015] Preferably, the first adjusting nut seat is threadedly connected to the expansion mechanism, and the first adjusting nut seat is slidably connected inside the adjusting groove.

[0016] Preferably, the expansion mechanism includes a holding handle, a lower expansion piece, and an upper expansion piece. The top of the holding handle is fixedly connected to the lower expansion piece, and the upper expansion piece is arranged above the lower expansion piece.

[0017] Preferably, the mating mechanism includes a second threaded rod, a second adjusting nut seat, and a limiting collar. The second threaded rod is inserted into the pressing plate, the second adjusting nut seat is sleeved on the outside of the second threaded rod, a limiting collar is fixedly connected to one side of the second threaded rod, a limiting buckle is buckled inside the limiting collar, and a mating spring is installed on the inner wall of one side of the mounting plate.

[0018] Preferably, one side of the mating spring is fixedly connected to the inner side wall of the pressing plate. The pressing plate is elastically telescopically connected to the mounting plate through the mating spring. The second adjusting nut seat is threadedly connected to the second threaded rod. The limiting buckle is fixedly connected to the outside of one side of the mounting plate, and the limiting buckle is slidably telescopically connected inside the limiting collar.

[0019] Preferably, the rotating mechanism includes a rotating shaft, a worm, and a worm gear. The rotating shaft is fixedly connected to the inside of the pressing plate, a worm is fixedly connected to one side of the rotating shaft, a worm gear is meshed with the top of the worm, and a connecting rod is fixedly connected to one side of the worm gear.

[0020] Preferably, the connecting rod is fixedly connected to the outside of the rotating gear. The worm gear rotates synchronously with the rotating gear through the connection of the connecting rod, and the worm gear is welded to the outside of one side of the connecting rod.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) Through the rotation shaft, worm, mounting seat and rotating gear provided in the present invention, when the pressing plate is pressed, the upper expansion piece will rotate at the top of the holding handle. At this time, the rotation shaft will rotate accordingly, driving the worm to rotate together. Since the worm gear meshes with the worm, this will cause the rotating gear to start rotating. Through the meshing connection between the rack plate and the rotating gear, the shielding plate will rotate around the lower expansion piece, thereby realizing the lifting of the shielding plate. This process can effectively shield the vaginal inner wall tissue and prevent it from filling into the dilator, thus preventing the influence on the observation field of view.

[0023] (2) Through the second threaded rod, second adjusting nut seat, limiting collar and limiting buckle provided in the present invention, under the action of elastic expansion and contraction, the pressing plate and the abutting spring cooperate with each other to keep the upper expansion piece in an elastically closed state. When it is necessary to open the upper expansion piece, only need to press the pressing plate. The limiting buckle will perform telescopic adjustment inside the limiting collar, thereby realizing the opening of the upper expansion piece. When the upper expansion piece is opened to a fixed angle, by rotating the second adjusting nut seat, its position is adjusted and fixed on the second threaded rod, and then the pressing plate is abutted. In this way, when performing a vaginal examination, there is no need to continuously hold the pressing plate, effectively improving the examination efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1:

[0033] Please refer to Figures 1 - 6 As shown, a gynecological vaginal dilator includes:

[0034] Mounting plate 1;

[0035] Adjusting mechanism 2, the adjusting mechanism 2 is arranged outside the mounting plate 1;

[0036] Expanding mechanism 3, the expanding mechanism 3 is installed outside the mounting plate 1;

[0037] Pressing plate 4, the pressing plate 4 is sleeved outside the mounting plate 1;

[0038] Shielding mechanism 7, the shielding mechanism 7 is arranged on the inner side wall of the expanding mechanism 3. The shielding mechanism 7 includes a mounting seat 701, a rotating gear 702 and a rack plate 703. The outside of the mounting seat 701 is rotatably connected with the rotating gear 702. The outside of the rotating gear 702 is engaged with the rack plate 703. The outside of the rack plate 703 is fixedly connected with a shielding plate 704. Two groups of rack plates 703 are arranged on the bottom surface of the shielding plate 704. Two shielding plates 704 are symmetrically arranged inside the expanding mechanism 3. The shielding plate 704 is an arc-shaped stainless steel plate. An engaging mechanism 5 is installed outside the pressing plate 4. A rotating mechanism 6 is installed on one side of the shielding mechanism 7.

[0039] Specifically, the mounting base 701 is installed at the top of the lower expansion piece 302 and is symmetrically arranged on both sides of the lower expansion piece 302. After the connecting rod 604 rotates, it can drive the rotating gear 702 to rotate on the mounting base 701. Thus, through the meshing connection between the rotating gear 702 and the rack plate 703, the baffle 704 can be lifted to block the tissues on the inner wall of the vagina.

[0040] As can be seen from the above, when the pressing plate 4 is pressed, the upper expansion piece 303 rotates at the top of the holding handle 301. At this time, the rotating shaft 601 rotates, driving the worm 602 to rotate. Since the worm gear 603 is meshed with the worm 602, the rotating gear 702 is driven to rotate. Through the meshing connection of the rack plate 703 on the rotating gear 702, the baffle 704 rotates around the lower expansion piece 302, thereby realizing the lifting of the baffle 704, which can block the inner wall tissues of the vagina and prevent the tissue structure of the inner wall of the vagina from filling into the dilator, thus affecting the observation of the field of view.

[0041] Reference Figure 2 and Figure 4 As shown in the figure, the adjusting mechanism 2 includes an adjusting groove 201, a first threaded rod 202, and a first adjusting nut seat 203. The adjusting groove 201 is opened on the outside of the mounting plate 1. The first threaded rod 202 is inserted into the adjusting groove 201. The first adjusting nut seat 203 is sleeved on the outside of the first threaded rod 202. The first adjusting nut seat 203 is threadedly connected to the expansion mechanism 3. The first adjusting nut seat 203 is slidably connected inside the adjusting groove 201. The expansion mechanism 3 includes a holding handle 301, a lower expansion piece 302, and an upper expansion piece 303. The top of the holding handle 301 is fixedly connected to the lower expansion piece 302, and the upper expansion piece 303 is arranged above the lower expansion piece 302.

[0042] Specifically, when it is necessary to adjust the distance between the upper expansion piece 303 and the lower expansion piece 302, by rotating the first adjusting nut seat 203, the mounting plate 1 can be telescopically adjusted on the outside of the first threaded rod 202 to realize the adjustment of the distance between the upper expansion piece 303 and the lower expansion piece 302.

[0043] Embodiment 2:

[0044] Reference Figures 1 - 6As shown in the figure, the abutting mechanism 5 includes a second threaded rod 501, a second adjusting nut seat 502 and a limiting collar 503. The second threaded rod 501 is inserted into the interior of the pressing plate 4. A second adjusting nut seat 502 is sleeved on the exterior of the second threaded rod 501. A limiting collar 503 is fixedly connected to one side of the second threaded rod 501. A limiting buckle 504 is buckled inside the limiting collar 503. An abutting spring 505 is installed on the inner wall of one side of the mounting plate 1. One side of the abutting spring 505 is fixedly connected to the inner side wall of the pressing plate 4. The pressing plate 4 is elastically telescopically connected to the mounting plate 1 through the abutting spring 505. The second adjusting nut seat 502 is threadedly connected to the second threaded rod 501. The limiting buckle 504 is fixedly connected to the exterior of one side of the mounting plate 1. The limiting buckle 504 is slidably telescopically connected inside the limiting collar 503. The rotating mechanism 6 includes a rotating shaft 601, a worm 602 and a worm gear 603. The rotating shaft 601 is fixedly connected to the interior of the pressing plate 4. A worm 602 is fixedly connected to one side of the rotating shaft 601. A worm gear 603 is meshed with the top end of the worm 602. A connecting rod 604 is fixedly connected to one side of the worm gear 603. The connecting rod 604 is fixedly connected to the exterior of the rotating gear 702. The worm gear 603 rotates synchronously with the rotating gear 702 through the connection of the connecting rod 604. The worm gear 603 is welded to the exterior of one side of the connecting rod 604.

[0045] Specifically, after the pressing plate 4 rotates, it can drive the rotating shaft 601 to rotate, thereby causing the worm 602 to rotate, enabling the worm gear 603 to rotate on the exterior of the worm 602.

[0046] As can be seen from the above, through the elastic telescoping between the pressing plate 4 and the abutting spring 505, the expanding upper piece 303 can be in an elastically closed state. At this time, by pressing the pressing plate 4, the limiting buckle 504 is telescopically adjusted inside the limiting collar 503, thereby realizing the opening of the expanding upper piece 303. When the expanding upper piece 303 is opened to a fixed angle, the second adjusting nut seat 502 is rotated, enabling the second adjusting nut seat 502 to be adjusted and fixed in position on the second threaded rod 501, thereby performing an abutting operation on the pressing plate 4.
