Abstract

The utility model relates to a vaginal dilator which is in particular manufactured by the hard plastics. The utility model is characterized in that the dilating fixing structure arranged between a pressing handle and a handle is composed of a hook and a buckle; when the utility model is in use, user only needs to press the pressing handle and then the hook can slide on the inclined surface of the buckle body; the utility model can quickly enter into the buckle by means of the elasticity of the hook or the buckle so as to make the utility model open an upper dilating sheet and a lower dilating sheet for fixing; thus the operation of the vaginal dilator is quick and convenient; in addition, the vaginal dilator manufactured by the plastics is low in cost; the utility model can be popularized and used as the disposable vaginal dilator, so that the utility model can save the disinfecting expenses and the disinfecting time, but also can break off the cross infection of the disease; therefore, the utility model has the better social benefits.

Description

Dilator for vagina

The present invention relates to be used in a kind of medical treatment the vaginal dilator of operations such as gynecologial examination or artificial abortion.

Vaginal dilator by two can around bearing pin rotate be duckbilled or olecranon-like on, following expanding plate is formed, opposite side at bearing pin, last expanding plate is provided with handle, following expanding plate is provided with handle, between handle and handle, also be provided with expansion fixed structure, known expansion fixed structure is the screw pair that screw rod and nut are formed, during use, the hand-held Shou Bing And of hands palpus presses handle makes expanding plate open around the bearing pin rotation, make it move to the position location with another hands rotating nut then, because this vaginal dilator is wanted bimanualness, travelling nut is taken time again, the doctor feels that operation was both time-consuming, and is inconvenient again.

The object of the present invention is to provide a kind of operation vaginal dilator easily rapidly.

Solving key of the present invention is that the expansion fixed structure of being made up of hook and button is set, and hook should have one to have elasticity with smashing, and button is provided with the inclined-plane that slides for hook.

The accompanying drawing of this description has:

Fig. 1: single hook-type vaginal dilator structure chart;

Fig. 2: many hook-types vaginal dilator structure chart;

Fig. 3: many buttons vaginal dilator structure chart.

Below in conjunction with accompanying drawing, content of the present invention is described in further detail.

To go up the same handle of expanding plate (1) (2) respectively and descend the same handle of expanding plate (3) (4) to be designed to one And hook (6) will be set on handle (2), on handle (4), be provided with and buckle (7), and button is provided with the inclined-plane (8) that slides for hook (6), cooperation by left and right bearing pin (5) and axis hole is assembled together two members then, has just formed vaginal dilator of the present invention.When upper and lower expanding plate (1) (3) open And by hook (6) and button (7) fixing after, the doctor can check relevant position or operation such as miscarry from the inspection door between the upper and lower expanding plate (1) (3), for the ease of observation to vaginal wall, upper and lower expanding plate (1) (3) can be provided with window, makes the vaginal dilator that is specifically designed to examination per vagina.The expansion fixed structure of being made up of hook (6) and button (7) has multiple design, introduces three kinds below.

Scheme one: form expansion fixed structure by a hook (6) one buttons (7), as shown in Figure 1.Vaginal dilator rigid plastics manufacturing, hook (6) has elasticity, and (8) produce strain to hook (6) when sliding along the inclined-plane, enter button (7) then under the elastic force effect, and open upper and lower expanding plate (1) (3) is fixed.

Scheme two: the expansion fixed structure of forming by hook with fan-shaped array (6) and rubber-like button (7), as shown in Figure 2.Button (7) is located on the flexure strip (11), flexure strip (11) is supported by two bolsters (9) (10) on the handle (4), when upper and lower expanding plate (1) (3) will close up, throw off rapidly in order to make hook (6) and button (7), establish dropout spanner (12) at an end of flexure strip (11), pull dropout spanner (12) backward, dropout spanner (12) will rotate And around bolster (10) and force flexure strip (11) to do crooked deformation, thereby reach the purpose that fastener is thrown off rapidly.

Scheme three: form expansion fixed structure by a button (7) and a hook (6) that the rubber-like engrail is arranged, as shown in Figure 3.The last And of buckle (14) that button (7) is located at the band flexure strip is installed on the boss of handle (4) by bolster (15), when hook (6) along the inclined-plane (8) when sliding, the flexure strip (13) of being close to handle (4) will be out of shape under the effect of buckle (14), after slipping over inclined-plane (8), the elastic force that discharges makes button (7) enter hook (6) rapidly, finishes the expansion of upper and lower expanding plate (1) (3) and fixes; Upwards pull buckle (14) with hands, flexure strip (13) also will be out of shape, and at this moment, fastener is thrown off, and upper and lower expanding plate (1) (3) closes up, and after loosing one's grip, the elastic force of release will make buckle (14) reset.

Vaginal dilator with above-mentioned expansion fixed structure, an available hand operated, expansion is carried out synchronously with expansion is fixing, and operation is certainly rapidly convenient, and expansion is fixing safe and reliable. In addition, Said structure is particularly suitable for making with rigid plastics, the vaginal dilator cost that plastics are made is low, in light weight, easy to carry, operation is light and handy, can be used as disposable vaginal dilator promotes the use of, like this, can save sterilization expense and the disinfecting time of apparatus, especially can break off the cross infection of disease, therefore, the vaginal dilator of promoting the use of this plastics manufacturing also has good social benefit.

Claims

1, a kind of vaginal dilator, form by last expanding plate, following expanding plate, bearing pin, handle, handle and expansion fixed structure, expansion fixed structure is located at handle with between the handle, the invention is characterized in: described expansion fixed structure is made up of hook (6) and button (7), button is provided with the inclined-plane (8) that slides for hook, and should have one to have elasticity in hook (6) and the button (7).

2, vaginal dilator according to claim 1, it is characterized in that: hook (6) is fan-shaped array, button (7) is located on the flexure strip (11), and flexure strip (11) is by the supporting of two bolsters (9) (10) on the handle (4), and flexure strip (11) also is provided with dropout spanner (12).

3, vaginal dilator according to claim 1 is characterized in that: button (7) is gone up indentation at buckle (14) and is arranged, and buckle (14) is provided with flexure strip, and (13) ， And are installed on the boss of handle (4) by bolster (15).
