Swirl Ring for Swirl Abortion Devices

Abstract

The swirl ring used for the rotary artificial abortion device includes a fixed tube, the fixed tube is a tubular structure, a metal rod that can pass through the fixed tube is arranged inside the fixed tube, and a metal rod made of a memory alloy is arranged at the front end of the metal rod. The fixing ring shrunk in the fixing tube, the present invention utilizes the combination of the rod, the fixing ring and the steel wire, when the operator pushes the fixing ring to the vicinity of the pregnancy tissue through the fixing tube, the user can adjust the width of the fixing ring by pulling the steel wire, Thereby expanding the outer diameter of the outer edge sweeping the arc during the rotation of the fixing ring along the central axis of the fixing tube, so that the fixing ring can be closer to the pregnancy tissue, so that the fixing ring can reach the pregnancy tissue more conveniently and use the fixing ring to move along the fixing tube The rotation of the central shaft wraps around the pregnancy tissue.

Description

technical field [0001] The invention relates to a swirl ring, more precisely a swirl ring for a swirling artificial abortion device. Background technique [0002] Publication No. CN2822539Y discloses a swirl ring for a swirling artificial abortion device. We found in application that the width of the elliptical ring structure of this swirl ring cannot be adjusted during the process of wrapping pregnancy tissue, although The elliptical ring deviates to one side, but due to the different structures of the inner wall of the individual uterus, sometimes the elliptical ring is still far away from the pregnancy tissue, so it is not easy to perform the wrapping operation. Contents of the invention [0003] The object of the present invention is to provide a swirl ring for a swirling artificial abortion device, which can combine a rod, a fixed ring and a steel wire. When the operator pushes the fixed ring to the vicinity of the pregnancy tissue through the fixed tube, the user Th...
