Abstract

The utility model provides a vagina automatic expander and belongs to the technical field of medical apparatus. The vagina automatic expander comprises a sleeve, a slide rod, a support spring, inverted L-shaped support rods and expansion arms. The vagina automatic expander is characterized in that the slide rod is movably arranged in the square sleeve in a sleeved mode, is matched with an inner cavity of the square sleeve, and an extrusion plate is arranged on the outer end of the slide rod. The support spring is connected between the inner end of the slide plate and the bottom of the sleeve, and limit pins are respectively fixed on the upper faces of the front side and the rear side of the inner end of the slide rod in a perpendicular mode. The two limit pins respectively penetrate through rectangle axial through holes which are symmetrically and formed in the front sleeve wall and the rear sleeve wall of the sleeve and then are exposed outside the sleeve. The inverted L-shaped support rods are symmetrically fixed on the upper side of the left end of the sleeve and the upper side of the right end of the slide rod in a perpendicular mode, and the symmetrically expansion arms are fixed on the front ends of horizontal rods of the two inverted L-shaped support rods in a perpendicular mode. The vagina automatic expander is simple in structure, simple and convenient to operate, and time-saving and labor-saving, can automatically expand the vagina in a gynecological disease examination, and reduces work amount of medical staff.

Description

Automatic vaginal dilator

Technical field: this utility model belongs to technical field of medical instruments, specifically a kind of automatic vaginal dilator.

Background technology: at present, when gynecologial examination, specula checks in the large multiplex duck-beak type clinically, this interior specula need to be pressed handle and can spy on its inner pathological changes situation, this method troublesome poeration after the expanded support arm probes into vagina, waste time and energy, increased medical worker's workload.

Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, and a kind of automatic vaginal dilator that can automatically vagina be strutted when gynecologial examination is provided.

The technical solution of the utility model is: this automatic vaginal dilator comprises sleeve, sliding bar, support spring, inverted "L" shaped support bar, expansion arm, slide in the square sleeve and be set with the sliding bar that the outer end that adapts with its inner chamber is provided with stripper plate, be connected with support spring between at the bottom of sliding bar the inner and the sleeve cylinder, vertically be fixed wtih respectively spacer pin above the both sides before and after sliding bar the inner, be exposed at the sleeve outside after two spacer pins pass respectively rectangle axially extending bore symmetrical above the barrel of sleeve front and back; Sleeve left end upside and sliding bar right-hand member upside are vertical respectively to be fixed wtih symmetrical inverted "L" shaped support bar, and the cross bar front end of two inverted "L" shaped support bars vertically is fixed wtih respectively symmetrical expansion arm.

During use, at the bottom of hands pinching pressing plate and the sleeve cylinder and make expansion arm close up rear insertion vagina, loosening sliding bar then, under the effect of support spring, expansion arm just can strut vagina automatically.

Advantage of the present utility model: simple in structure, easy and simple to handle, time saving and energy saving, when checking, gynaecopathia vagina can be expanded automatically, alleviate medical worker's workload.

Description of drawings: Fig. 1 is structure chart of the present utility model.

The specific embodiment: this utility model is described in further detail below in conjunction with Fig. 1: this automatic vaginal dilator comprises sleeve 1, sliding bar 2, support spring 3, inverted "L" shaped support bar 4, expansion arm 5, square sleeve 1 interior slip is being set with the sliding bar 2 that the outer end that adapts with its inner chamber is provided with stripper plate 6, be connected with support spring 3 between at the bottom of 1 in the inner and sleeve of sliding bar 2, vertically be fixed wtih respectively above the both sides, sliding bar 2 inner front and back and be exposed at sleeve 1 outside after 7, two spacer pins 7 of spacer pin pass respectively rectangle axially extending bore symmetrical above the sleeve 1 front and back barrel; Sleeve 1 left end upside and sliding bar 2 right-hand member the upsides respectively vertical cross bar front end that is fixed wtih symmetrical 4, two inverted "L" shaped support bars 4 of inverted "L" shaped support bar vertically are fixed wtih respectively symmetrical expansion arm 5.
