Abstract

The present invention relates to a vaginal dilator which is in particular manufactured by the hard plastics. The present invention 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 present invention 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 present invention can quickly enter into the buckle by means of the elasticity of the hook or the buckle so as to make the present invention 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 present invention can be popularized and used as the disposable vaginal dilator, so that the present invention can save the disinfecting expenses and the disinfecting time, but also can break off the cross infection of the disease; therefore, the present invention has the good social benefits.

Description

Vaginal dilator

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, a hands must be handed handle and press handle expanding plate is opened 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.

Solve key of the present invention and form expansion fixed structure by the hook and the button of one-sided setting, hook should have one to have elasticity with smashing, and button is provided with the inclined-plane that slides for hook.

Another solution of the present invention is by on the buckle that is arranged on the band flexure strip, and button and a hook that engrail is arranged are formed expansion fixed structure, button is provided with the inclined-plane that slides for hook, and buckle is installed in by bolster on the boss of being located at handle, and flexure strip then divides the both sides that are located at axis hole.

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 expanding plate 1 respectively and be designed to one with handle 4 with handle 2 and following expanding plate 3, and hook 6 is 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 opens, 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.By hook 6 and button 7 expansion fixed structures of forming multiple design is arranged, introduce 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 hook 68 produces strain when sliding along the inclined-plane, enters 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 6 with fan-shaped array and rubber-like button 7, as shown in Figure 2.Button 7 is located on the flexure strip 11, flexure strip 11 is by 9,10 supportings of two bolsters on the handle 4, when upper and

lower expansion

1,3 will be closed up, throw off rapidly in order to make hook 6 and button 7, open an end of 11 in elasticity and establish dropout spanner 12, pull dropout spanner 12 backward, dropout spanner 12 will rotate 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 button 7 and a hook 6 that the rubber-like engrail is arranged, as shown in Figure 3.Button 7 is located on the buckle 14 of band flexure strip 13, and be installed on the boss of being located at handle 4 by bolster 15, flexure strip was located at the both sides of axis hole in 13 minutes, when hook 6 along the inclined-plane 3 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 of release 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 convenient rapidly certainly, and expansion is fixing safe and reliable.In addition, said structure is suitable for using the rigid plastics manufacturing especially, and 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 and promotes the use of, like this, can save the 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.
