Abstract

The invention discloses a four-wing vaginal dilator which comprises an upper dilation assembly, a lower dilation assembly and a side dilation assembly, the lower dilation assembly comprises a lower dilation piece, a handheld piece and a side dilation acting piece, the lower dilation piece is connected with the handheld piece, the side dilation acting piece is arranged on the side, close to the lower dilation piece, of the handheld piece, the side dilation assembly comprises a side dilation linkage piece and two side dilation pieces, the side dilation linkage piece is rotationally connected to the handheld piece, the upper dilation assembly is connected with the side dilation linkage piece, one ends of the two side dilation pieces are connected with the side dilation linkage piece, the other ends of the two side dilation pieces extend in the direction away from the side dilation linkage piece and pass through the side dilation acting piece, in the relative opening process of the upper dilation assembly and the lower dilation piece, the upper dilation assembly drives the side dilation linkage piece to rotate, the side dilation linkage piece drives the two side dilation pieces to swing and pass through the side dilation acting piece, and the side dilation acting piece acts on the two side dilation pieces and enables the two side dilation pieces to be oppositely opened. The four-wing vaginal dilator is simple in structure, low in cost and convenient to operate during medical examination.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a four-winged vaginal dilator. Background technique [0002] For the screening of gynecological diseases, medical device products for screening are constantly being innovated at home and abroad, among which improving the vaginal dilator from two wings to four wings is a relatively mainstream improvement. However, the structure of the existing four-wing vaginal dilator is relatively complicated, and the cost is relatively high. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a four-wing vaginal dilator. [0004] A four-wing vaginal dilator disclosed by the present invention includes an upward expansion component; [0005] The lower expansion assembly includes a lower expansion piece, a handpiece and a side expansion piece, the lower expansion piece is connected to the handpiece, the side expansion piece is arranged...
