Abstract

The invention relates to a vaginal dilating instrument for gynecological examination, which includes an upper dilating sheet, a lower dilating sheet and a lighting assembly. The lighting assembly includes a plastic light source box, a battery, and a light emitting diode. The light source box has two pairs of symmetrically arranged left wings and On the right side, the battery is arranged inside the light source box, and the light-emitting diodes are set out from the bottom of the light source box. The upper expansion sheet has a light source installation hole, and the shape of the light source installation hole matches the shape of the light source box. During inspection, it can illuminate the inside of the vagina for easy inspection, and the lighting assembly can be detachably installed on the expansion device. The expansion device is a one-time use product, but the lighting assembly can be used repeatedly to avoid waste. In addition, the lighting assembly The switch is associated with the handle of the expansion device. When the expansion device is in a closed state, the lighting assembly does not emit light. When the expansion sheet of the expansion device is gradually opened, the lighting assembly is activated for lighting.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a vaginal expansion device for gynecological examination. Background technique [0002] Vaginal dilation device means that when a doctor is doing a gynecological examination, he uses the dilator (usually for one-time use) to open the vaginal opening, open the front and rear walls of the vagina, and see the condition in the vagina.
