Disposable vaginal dilator

Abstract

The invention provides a disposable vaginal dilator. The disposable vaginal dilator comprises an upper dilation sheet and a lower dilation sheet, wherein the upper dilation sheet is hinged to the lower dilation sheet; the upper dilation sheet comprises an upper wing and a push rod, and the push rod is integrally connected with the upper wing; an inspection hole is formed in the upper dilation sheet; the lower dilation sheet comprises a lower wing, a lower handle and a positioning rod, the lower handle is integrally connected with the lower wing, and the positioning rod is fixedly arranged on the lower handle; clamping teeth I are arranged on the side surface of the push rod, and a plurality of clamping teeth II are arranged on the side surface of the positioning rod and are buckled with the clamping teeth I. The disposable vaginal dilator has the advantages that by utilizing the principle that the clamping teeth I on the push rod can only be slide along the clamping teeth II on the positioning rod in a unidirectional way, the clamping teeth I and the clamping teeth II are respectively arranged on the side surfaces, the separating and buckling are controlled by the self elasticity of the material, and the dilation and fixation can be completed by one hand; when the dilation sheet is opened, the failure to opening due to overlarge elasticity of the push rod is avoided, the error produced in the cervix uteri or vaginal disease measuring process is reduced, and the measuring accuracy of data is guaranteed.

Description

technical field [0001] The invention relates to a medical device for gynecological examination, family planning and other operations, in particular to a disposable vaginal dilator. Background technique [0002] Common vaginal dilators currently on the market 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 complicated fixing structures and difficult operation Inconvenience and other problems, or must be completed by two-handed operation, which brings inconvenience to inspection or operation. There are also some vaginal dilators that can be operated with one hand at present, most of which are equipped with toothed adjustment rods on the lower expansion sheet, and the upper expansion sheet is equipped with corresponding reverse teeth or holes. Although this structure can be operated with one hand, it has poor flexibility, and ...

Problems solved by technology

Although this structure can be operated with one hand, it has poor flexibility, and each time it is opened and closed, the collision between the locking teeth will generate vibration, which will cause discomfort to the patient

At the same time, none of the vaginal dilators currently on the market have measurement functions, s
