Abstract

The utility model relates to a vaginal speculum, belonging to the technical field of the medical utensils, which is composed of an upper body (1) and a lower body (2). The front parts of the upper body and the lower body totally forms duckbill device shapes. The utility model is characterized in that the middle part of the upper body (1) is provided with a strip-shaped hole (3); both sides at the lower part of the upper body are respectively provided with a positioning block (4). The middle part of the lower body (2) is provided with a right angle hole (5). One side of the right angle hole is provided with two to six tooth spaces. Both sides at the middle part of the lower body (2) are respectively provided with a lug (6). The lugs are clamped in the strip-shaped hole (3) of the upper body (1), and the lugs drive the lower body which can slide up and down. The positioning block (4) of the upper body (1) is clamped and positioned in the right angle hole (5) of the lower body (2). The utility model has the advantages of simple structure and convenient use. When in use, one hand upwards (or downwards) pushes the upper body (1), the positioning block (4) is clamped and positioned on teeth in the right angle hole (5), so as to control the opening-closing degree of the vaginal speculum.

Description

Vaginal speculum

This utility model relates to a kind of vaginal speculum, belongs to the medical apparatus technical field.

Existing vaginal speculum, the degree of its folding are cooperated by screw rod and nut and limit.Example Chinese patent " vaginal dilator " (CN2119241V), the operator must push handle on the other hand during use, on the other hand the turn nut just can make the vaginal speculum location, it is time-consuming again, very inconvenient to require great effort.

The purpose of this utility model is will provide a kind of to fix the vaginal speculum of vaginal speculum folding degree with slide block, the hole, right angle, the locating piece that have a teeth groove, and is simple in structure, easy to operate and use.

The purpose of this utility model is achieved in that vaginal speculum is made up of upper body, lower body, and upper body and lower body front portion all are duckbill, and upper body (1) middle part has bar hole, and both sides, below, upper body respectively are provided with a positioning block; The lower body middle part has the hole, right angle, on one side the hole, right angle is provided with 2--6 teeth groove, both sides, lower body middle part respectively are provided with projection, and the projection card is put in the bar hole of upper body, and projection drives lower body and can slide up and down; The locating piece card of upper body is put in the hole, right angle of lower body.

Compared with prior art, this utility model has following advantage: simple in structure, easy for operation.

Fig. 2 is the A-A cutaway view;

Fig. 3 is the B-B cutaway view;

Hole, 2--lower body 3--bar blocks 4--locating piece 5--right angle, 1--upper body 6--slide-bar

Now further specify operation principle of the present utility model in conjunction with the accompanying drawings.

As shown in Figure 1, vaginal speculum is made up of upper body (1) and lower body (2), and upper body and lower body front portion all are to be duckbill, it is characterized in that middle part, upper body (1) has bar hole (3), and respectively there is a positioning block (4) both sides, below, upper body; Lower body (2) middle part has hole, right angle (5), on one side the hole, right angle is provided with 2--6 teeth groove, both sides, lower body (2) middle part respectively are provided with projection (6); The projection card is put in the bar hole (3) of upper body (1), and projection drives lower body can slide up and down (referring to Fig. 3); The locating piece (4) of upper body (1) blocks in the hole, right angle (5) that is put in lower body (2) (referring to Fig. 2).Can only need to go up (or down) as required and push to body (1), locating piece (4) card is put on the tooth among the hole, right angle (5), control the folding degree of vaginal speculum with a hands.When on when pushing to body (1) and making the tooth of locating piece (4) above blocking in the hole, right angle (5), vaginal speculum folding degree maximum, when pushing to body (1) instantly and making locating piece (4) be stuck in the cross-drilled hole in hole, right angle (5), vaginal speculum folding degree is minimum promptly closed.
