AI Technical Summary

Technical Problem

After the existing four-wing dilated structure expands the vagina, its support effect on the vagina often fails to meet expectations.

Method used

A vaginal dilator is designed, which includes an upper expansion member, a lower expansion member and a side expansion member. Through the opening action of the upper expansion member, the side expansion member is driven to open relative to each other to form a support channel, and the upper expansion member is unidirectionally restricted through the unlocking member and the locking member to maintain the stability of the support channel.

Benefits of technology

The supporting channel is formed by combining the upper expansion and the side expansion, which significantly improves the support effect of the vagina, making the support shape better, the support space regular, and suitable for gynecological examinations.

Abstract

The present invention discloses a vaginal dilator, which includes an expansion component, a side expansion component and a locking and unlocking component. The expansion component includes an upper expander and a lower expander. The upper expander is rotatably connected to the lower expander. The upper expander and the lower expander can be relatively opened or closed. The side expansion component includes two side expanders. The two side expanders are respectively rotatably connected to the lower expander and are respectively movably connected to the upper expander. The locking and unlocking component includes an unlocking component and a locking component. The unlocking component is provided at the lower expander, and the locking component is provided at the upper expander. The unlocking component and the locking component are connected. The present invention also discloses a medical device. The present application directly drives the two side expanders to open relatively to form a support channel through the opening action of the upper expander, and then the upper expander is unidirectionally restricted by the unlocking component and the locking component to maintain the stability of the support channel, thereby ensuring the support effect of the dilator on the vagina.
