Disposable colpectasia apparatus

Abstract

The invention relates a medical surgical apparatus used for gynecological examination, family planning, etc., in particular to a disposable vagina dilator. The disposable vagina dilator comprises a lower dilation piece and an upper dilation piece. The lower dilation piece comprises a lower wing with a left and a right axle pins and a lower handle, and the upper dilation piece comprises an upper wing and an upper handle which is provided with a left and a right axle holes and an examination hole. The left and the right axle pins of the lower dilation piece are connected with the left and the right axle holes of the upper dilation piece by pins. The lower handle of the lower dilation piece is provided with a dilation regulation bar which is provided with inclined buckling teeth, the upper handle of the upper dilation piece is equipped with a locating buckle, and the locating buckle is locked with the inclined buckling teeth of the dilation regulation bar. The disposable vagina dilator has a simple structure that the locating buckle is locked with the inclined buckling teeth of the dilation regulation bar, thus the dilation and locating operations can be finished by one hand. A control board part is arranged on the locating buckle, when the control board part is slightly pressed, the dilation angle is changed and firmly fixed. The apparatus is not operated by two hands, thus the operation and examination time is shortened.

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 in medical treatment are composed of duckbill-shaped or olecranon-shaped upper and lower dilators, and are connected by shaft pins and shaft holes on the upper and lower dilators, but most of them have complicated fixing structures and difficult operation For problems such as inconvenience, there are also single-hook or multi-hook expansion and fixation structures.

Problems solved by technology

[0002] Common vaginal dilators in medical treatment are composed of duckbill-shaped or olecranon-shaped upper and lower dilators, and are connected by shaft pins and shaft holes on the upper and lower dilators, but most of them have complicated fixing structures and difficult operation Inconvenience and other problems, there are also single-hook or multi-hook expansion and fixation structures. Although the structure is simplified a lot, 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, the lower expansion piece is fixed with a toothed adjustment rod, and the upper expansion piece has a hole that can be engaged with the teeth. Although this structure can be operated with one hand, the Every time the opening and closing angle is adjusted, the teeth on the adjustment rod will collide with the holes of the upper expansion piece to make a sound, and at the same time, the dilator will vibrate, thus causing pain or discomfort to the patient
