Abstract

The utility model discloses a vaginal speculum used for exposing soft birth canal and the vaginal speculum belongs to the special equipment of the obstetric department. The utility model is composed of a pressing board installed on an n-shaped guiding column and an annular steel mold. The distance and the included angle between the pressing board and an annular steel wire can be regulated. When the utility model is in use, the included angle and the distance between the pressing board and an annular steel wire is regulated to the minimum value to make the vaginal speculum be put in the vagina. After the vaginal speculum is put in the vagina, the inclined angle and the distance can be regulated to the proper value according to the actual requirement. The utility model can sufficiently expose the soft birth canal so as to conduct various sewing operations and gynecological examination; the utility model can substitute the vagina draw hook and can substitute the existing two-lobe type vaginal speculum; the utility model has the advantages of simple structure and convenient use; the utility model can be popularized for the obstetric department in various hospitals and the department of female health protection.

Description

Multifunctional speculum for vagina

The utility model proposes a kind of vaginal speculum that is used to expose soft birth canal,, belong to the department of obstetrics and gynecology special implement so that carry out soft birth canal inspection and stitching, vagina and operations such as cervix uteri inspection, intrauterine surgical.

The wound that perineum, vagina and the cervix uteri etc. that the puerpera is caused are in process of production located carries out hemostatic suture, is the routine work that meets the survivor.Need before the hemostatic suture to expose wound, existing way is a vaginal tractor.The shortcoming of this way is: wound exposes incomplete, cause wound involutory not good, sew up difficulty, wound bleeding is many and consequence such as easy infection.

The purpose of this utility model is a kind of vaginal speculum that can comprehensively expose wound of design.This vaginal speculum not only can replace vaginal tractor, and can carry out gynecologial examination, replaces existing two-piece type vaginal speculum.

The object of the present invention is achieved like this: take the guide pillar that two rustless steels are made, the connecting rod with a rustless steel is made links to each other with the end of two guide pillars, forms a ∏ shape guide rail.Distance between guide pillar (being the width of ∏ shape guide rail) is about 5～6 centimeters.The other end at two guide pillars connects a ring like steel wire, and planar hinge is equipped with in the junction.Rely on planar hinge, the angle between the plane that plane that the shape guide rail forms and ring like steel wire form can be regulated.About 12 centimeters of the height of ring like steel wire also is equipped with a pressing plate that can move back and forth along guide pillar on ∏ shape guide rail, the pressing plate head is the garden arc.The pressing plate height is about 9 centimeters.

Using method is: (1) pushes pressing plate to ring like steel wire, and regulates the angle between ring like steel wire and ∏ shape guide pillar, makes pressing plate and ring like steel wire close as far as possible.(2) hands is taken ∏ shape guide rail, and pressing plate and ring like steel wire are sent into intravaginal.(3) regulate pressing plate and the distance of ring like steel wire and the angle of ring like steel wire and ∏ shape guide pillar, be as the criterion, fixed then with abundant exposure wound.

Advantage of the present invention is: (1) soft birth canal exposes fully, and is easy to operate, and can improve suture quality; (2) remove vaginal tractor work from.Save manpower; (3) can replace existing two-piece type vaginal speculum and carry out gynecologial examination, accomplish one-object-many-purposes.

Introduce embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is the population structure sketch map of multi-functional vaginal speculum;

Fig. 2 is a ∏ shape guide rail structure sketch map;

Fig. 3 is the pressure plate structure sketch map;

Fig. 4 is the ring like steel wire structural representation.

Referring to Fig. 1, as seen from the figure, multi-functional vaginal speculum is made up of ∏ shape guide rail (1), pressing plate (2) and ring like steel wire (3).Pressing plate (2) can move back and forth along ∏ shape guide rail (1), move to the appropriate location after, located with dog screw (6).The end of the end of ring like steel wire (3) and ∏ shape guide rail (1) is hinged with planar hinge (4), on ring like steel wire (3), with two pins (21), about respectively be fixed with a limiting plate (7), a garden arc guide groove (8) is arranged on the limiting plate (7), a stop screw (5) that is fixed on the ∏ shape guide rail (1) is arranged in the gathering sill (8), when ring like steel wire (3) when planar hinge (4) rotates, gathering sill (8) on the limiting plate (7) slides along stop screw (5), when forwarding required angle to, tighten stop screw (5), ring like steel wire (3) is promptly located.

Referring to Fig. 2, as seen from the figure, ∏ shape guide rail (1) is made up of two garden shape guide pillars (9) and a connecting rod (10), fix with screw or rivet (11) between garden shape guide pillar (9) and the connecting rod (10), be linked to be a ∏ shape structure, the free end of two garden shape guide pillars (9) respectively has two holes: hole (12) are used to lay planar hinge (4), and ∏ shape guide rail (1) and ring like steel wire (3) are hinged: screw (13) is used to lay stop screw (5).

Referring to Fig. 3, as seen from the figure, pressing plate (2) is made up of pressing plate body (14) and pressing plate seat (15), fix with the method for bonding or welding between the two, fuse, two pilot holes (16) are arranged on the pressing plate seat (15), and pilot hole (16) becomes to be slidingly matched with two garden shape guide pillars (9) on the ∏ shape guide rail (1).Other has two screws (17) to communicate with pilot hole (16), is used to lay dog screw (6).After pressing plate (2) moves to the appropriate location, located with dog screw (6).

Referring to Fig. 4, ring like steel wire (3) is made up of steel wire (18), two steel wire seats (19) and two limiting plates (7).With being threaded or boning, make it to be fixed into one between steel wire (18) and two the steel wire seats (19).Two steel wire seats (19) are gone up each and are made a call to two holes (20), are used for mounting plane hinge (4).Two limiting plates (7) become fixedly connected with rivet (21) with steel wire (18).Limiting plate (7) and the gathering sill on it (8) are the garden arc, when ring like steel wire (3) rotated, gathering sill (8) was along sliding with the stop screw (5) that is threaded with ∏ shape guide rail (1), when going to required angle, tighten dog screw (5), make ring like steel wire (3) location.

This utensil should all use rustless steel to make, in case get rusty infected patient.
