Dilatable mesh stent type vaginal dilatation instrument

Abstract

The invention discloses a dilatable mesh stent type vaginal dilatation instrument. The dilatable mesh stent type vaginal dilatation instrument comprises an expanded cylindrical expansion mesh. An expansion mesh expansion structure is disposed in the expansion mesh. The dilatable mesh stent type vaginal dilatation instrument is characterized in that the expansion mesh expansion structure comprisesa central rod and a sleeve connected to the outer side of the central rod in a sleeving mode; relative movement is performed between the sleeve and the central rod; 2-4 support rods capable of expanding the expansion mesh and rotating along the joints on the central rod and the sleeve are uniformly arranged around the central rod or sleeve; the front ends of the support rods are connected with longitudinal curved plates; and the curved plates are closely attached to the inner wall of the expansion mesh without relative position change. Through the arrangement of the structure, the relative movement between the central rod and the sleeve is realized, the contraction and expansion of the support rods are driven, the contracted dilatation instrument is extended into a vagina during use, the relative movement between the central rod and the sleeve is realized to achieve the purposes of expanding the support rods and driving the expansion mesh to be expanded, and then an initial state of the central rod and the sleeve is restored after the expansion mesh is expanded, so that the central rod and the sleeve are enabled to be withdrawn from the expansion mesh.

Description

technical field [0001] The invention belongs to the technical field of auxiliary instruments for vaginal surgery, in particular to an instrument for dilating the vagina before vaginal surgery, in particular to a vaginal expansion instrument of the expandable mesh stent type. Background technique [0002] At present, with the progress of society, people are paying more and more attention to their own health, and the degree of attention to gynecological diseases has also been increased. Sometimes for some gynecological diseases, such as operations on the cervix, vaginal side wall and inside of the uterus, vaginal implants are required. In order to ensure the effective placement of each operating instrument and the clarity of the surgical field of view, before transvaginal surgery, it is necessary to expand the vagina to facilitate the operation after the insertion of various surgical instruments and to make the surgical field of view better. exposure. [0003] There are many ...
