Safe instant-destruction type disposable vaginal dilator

Abstract

The invention relates to a safe instant-destruction type disposable vaginal dilator which comprises a lower dilation plate and an upper dilation plate, wherein the left and right axle pins of the upper dilation plate are in pin joint with the left and right axle holes of the lower dilation plate. The vaginal dilator is characterized in that the lower dilation plate comprises a lower wing with the left and right axle holes, a lower handle and an instant-destruction dilation regulating rod with inclined sprockets, and the instant-destruction dilation regulating rod and the lower handle are connected into a whole; the upper dilation plate comprises an upper wing with the left and right axle pins, an upper handle and a positioning slide plate; an inspection port, a notch to be penetrated by the instant-destruction dilation regulating rod and a mounting hole of the positioning slide plate are formed on the upper handle; and the positioning slide plate can be pushed upward to be buckled with the inclined sprockets on the instant-destruction dilation regulating rod passing through the notch. Compared with the prior art, the vaginal dilator has the advantages that the positioning slide plate is buckled with the inclined sprockets on the instant-destruction dilation regulating rod, and the vaginal dilator is destructed by slightly pushing backward the front end of the instant-destruction dilation regulating rod; the structure is simple, and easy to destroy; and dilation, positioning and destruction can be carried out by a single hand.

Description

technical field [0001] The invention relates to a safe and instant disposable vaginal dilator used in clinical diagnosis, treatment and operation of female reproductive system. Background technique [0002] Common vaginal dilators in medical treatment are composed of duckbill-shaped or olecranon-shaped upper and lower expansion pieces, and are connected by the shaft pins and shaft holes of the upper and lower expansion pieces, but most of them have complex fixing structures and operational difficulties. Inconvenience and other issues. There is also a single-hook or multi-hook expansion fixation structure, although the structure is simplified a lot, but this kind of structure must be operated with both hands, which brings inconvenience to the operation.

Problems solved by technology

[0002] Common vaginal dilators in medical treatment are composed of duckbill-shaped or olecranon-shaped upper and lower expansion pieces, and are connected by the shaft pins and shaft holes of the upper and lower expansion pieces, but most of them have complex fixing structures and operational difficulties. Inconvenience and other issues

There are also single-hook or multi-hook expansion and fixation structures. Although the structure is much simplified, this structure must be implemented with both hands, which brings inconvenience to the operation.

At present, there are also some vaginal dilators that can be operated with one hand. Generally, an expansion adjustment rod with oblique teeth is fixed on the handle on one side of the upper expansion piece, and it is positioned with a buckle on one side of the handle of the lower expansion piece. Although this structure can One-handed operation, but due to unilateral positioning during expansion, the upper and lower wings of the expansion piece are squeezed by the vaginal wall, and the upper wing will be deformed, which will cause pain or discomfort to the patient

In addition, the existing vaginal dilators generally do not have a self-destruct structure, even if there is a self-destruct structure, it is unreasonable or inconvenient to operate
